BackgroundAcute pain due to rib fractures causes significant in-hospital morbidity and impacts patients’ quality of life after discharge. Intraoperative transthoracic cryoneurolysis of the intercostal nerves can improve postoperative pain; however,...

Efficacy of a Multimodal Surgical Site Injection for Postoperative Pain Control in Pediatric Patients With Cerebral Palsy Undergoing Hip Reconstruction: A Randomized Controlled Trial.

One in 4 children with cerebral palsy (CP) will undergo orthopaedic surgery during their childhood. Despite its ubiquity, postoperative pain control has been poorly studied in this patient population. Moreover, poor pain management has been associated with adverse surgical outcomes. Multimodal analgesic injections have been well studied in the adult population, demonstrating safety and efficacy in reducing postoperative pain and narcotic consumption, but this modality has not been studied in pediatric patients undergoing similarly complex procedures. The objective of this study was to evaluate the efficacy of a multimodal surgical site injection for postoperative pain control following operative management of hip dysplasia in patients with CP. After obtaining IRB approval, a multicenter, randomized double-blind placebo control trial was completed. Patients below 18 years old with a diagnosis of CP who were scheduled for varus derotation osteotomy (VDRO) of the proximal femur were randomized to receive a surgical-site injection with either a combination of ropivacaine (3mg/kg), epinephrine (0.5mg), and ketorolac (0.5mg/kg) (experimental group) or normal saline (control). All included patients had identical postoperative care, including immobilization, physical therapy, and standardized, multimodal postoperative pain control. Pain scores and narcotic consumption were recorded at regular intervals and compared between groups utilizing two-tailed t test or a nonparametric Mann-Whitney test for quantitative variables and a Fischer exact test for categorical variables. Thirty-four patients were included, evenly divided between study arms. There were no significant differences in demographic variables, gross motor function classification system (GMFCS), comorbidities, preoperative radiographic parameters, or concomitant surgeries between groups. Patients in the experimental group required significantly lower narcotic medications at all postoperative time points from PACU until hospital discharge compared with controls (0.41 ± 0.42 vs. 1.87 ± 2.05 total morphine mEQ/kg, P=0.01). Similarly, patients in the experimental group were found to have significantly lower pain scores throughout their hospital stays compared with controls (1.0 ± 0.6 vs. 2.4 ± 1.1 mean pain score, P<0.001). There were no significant differences in operative time, OR time, blood transfusion requirements or hospital length of stay between groups. There were no adverse medication reactions or injection site complications in either group. In patients with CP undergoing hip reconstruction, surgical-site injection with a multimodal analgesic combination improves pain control and reduces narcotic consumption in the early postoperative period with no observed adverse effects. Local multimodal analgesic injections should be adopted as part of standard multimodal pain control in this patient population for all osseous surgeries. Level I-therapeutic.

Association Between Low-Dose Ketamine After Periacetabular and/or Femoral Osteotomy and Postoperative Opioid Requirements.

Previous studies have sought to determine the effect of inpatient ketamine therapy on postoperative pain in a variety of surgical specialties. To determine the effects of postoperative ketamine analgesia after periacetabular osteotomy (PAO) and/or derotational femoral osteotomy (DFO) on opioid requirements, pain, and discharge time. Cohort study; Level of evidence, 3. Prospective data were collected on 145 patients who underwent PAO and/or DFO by the senior author between January 2021 and December 2022. Hip arthroscopy was performed 3 to 10 days before addressing any intra-articular pathology. In 2021, patients (n = 91 procedures; control group) received a traditional postoperative multimodal pain regimen. In 2022, postoperative low-dose ketamine (0.1-1 mg/kg/h) was added to the multimodal analgesic approach until 24 hours before discharge (n = 81 procedures; ketamine group). The ketamine and control groups were matched based on procedure type. Total opioid consumption was collected using milligram morphine equivalents (MMEs) for both groups. Postoperative pain was measured using the Defense and Veterans Pain Rating Scale (DVPRS), which was analyzed as the mean score per day. Data on the mean MME and DVPRS were analyzed for up to 7 days postoperatively. Linear mixed statistical analysis was performed to determine the significance of low-dose postoperative ketamine on postoperative pain and opioid utilization. Patients who did not receive ketamine after PAO and/or DFO utilized a mean of 181 ± 335 MMEs and had a mean DVPRS score of 4.18 ± 1.63. Patients who received postoperative ketamine required a mean of 119 ± 291 MMEs and had a mean DVPRS score of 4.34 ± 1.61. The ketamine group was found to consume a significantly lower total MME dose per day (P < .001). No significant difference was found in the mean DVPRS score between the ketamine and control groups (P = .42). Also, no significant difference was found on the day of discharge (P = .79). Patients who received postoperative ketamine after PAO and/or DFO had a significant decrease in MME dose when compared with a control group of patients who did not receive ketamine. Surgeons should consider adding ketamine to their postoperative multimodal pain control protocol to decrease opioid consumption while adequately addressing postoperative pain.

Study of Efficacy of Extraosseous Local Infiltration of Multimodal Drug Cocktail for Pain Management After Total Joint Arthroplasty in Lower Limb.

Background Osteoarthritis (OA) is a chronic debilitating condition involving joints that ultimately leads to chronic pain, restricted mobility, and functional impairment of the joint. The gold standard treatment of end-stage OA is arthroplasty. Following arthroplasty surgery, patients might have excruciating pain in the postoperative period. Our study aimed to evaluate the beneficial effects of a multimodal drug cocktail in patients who underwent arthroplasty surgery concerning postoperative pain and knee range of motion during the healing period. Materials and methods In this randomised case-control study, we enrolled 32 patients, of which 16 patients had knee arthritis and underwent total knee replacement. In contrast, the other 16 patients had hip arthritis and underwent total hip replacement. Randomisation was done using simple random sampling (envelope method), and patients were divided into groups A and Baccordingly. Group A consists of a postoperative pain management modality using epidural analgesia with a top-up at a 12-hour interval. Group B consists of a postoperative pain management modality using an extraosseous multimodaldrugcocktail consisting of clonidine, cefuroxime, tramadol, bupivacaine, adrenaline, and normal saline in specific quantities. Visual analogue scale (VAS) was assessed post-surgery for walking and resting. Joint range of movement and walking distance were assessed post-surgery and compared between the two groups. Results A total of 32 patients who had OA and underwent total knee arthroplasty (TKA) and total hip arthroplasty (THA) were selected and divided into case and control groups of eight, each by simple random sampling (envelope method).The mean preop VAS scores for the epidural and cocktail groups were 7.88 ± 0.61 and 7.44 ± 0.62, respectively, with p = 0.057, which is insignificant. However, when the groups were compared based on VAS score while standing at 24, 48, and 72 hours, the standing VAS score was found to be significantly higher among subjects, given epidural analgesia with p-values of 0.001, 0.001, and 0.001 at 24, 48, and 72 hours, respectively, which is significant in our study. Also, postoperatively, at 24, 48, and 72 hours, the mean degree of movement was found to be significantly higher among subjects, given cocktail analgesia with p-values of 0.013, 0.001, and 0.001, respectively. Conclusion As a result of early postoperative pain alleviation, the current study concludes that multimodal pain control procedures, which combine more than two medications with distinct mechanisms of action, successfully increase patient satisfaction. A multimodal medication conjunction administered locally to patients resulted in improved functional outcomes, faster recovery, and better rehabilitation.

Single-shot interscalene block with liposomal bupivacaine vs. non-liposomal bupivacaine in shoulder arthroplasty

Regional anesthesia is a valuable component of multimodal pain control in total shoulder arthroplasty (TSA), and multiple interscalene block anesthetic options exist, including nonliposomal interscalene bupivacaine (NLIB) and liposomal interscalene bupivacaine (LIB). The purpose of this study was to compare pain control and opioid consumption within 48 hours postoperation in those undergoing TSA with either LIB or NLIB. This was a retrospective cohort study at a single academic medical center including consecutive patients undergoing inpatient (>23-hour hospitalization) primary anatomic or reverse TSA from 2016 to 2020 who received either LIB or an NLIB for perioperative pain control. Perioperative patient outcomes were collected including pain levels and opioid usage, as well as 30- and 90-day emergency department (ED) visits or readmissions. The primary outcome was postoperative pain and opioid use. Overall, 489 patients were included in this study (316 LIB and 173 NLIB). Pain scores at 3, 6, 12, and 48 hours postoperatively were not statistically significantly different (P>.05 for all). However, the LIB group had improved pain scores at 24 and 36 hours postoperation (P<.05 all). There was no difference in the incidence of severe postoperative pain, defined as a 9 or 10 numeric rating scale-11 score, between the 2 anesthesia groups after adjusting for preoperative pain and baseline opioid use (odds ratio 1.25, 95% confidence interval 0.57-2.74; P=.57). Overall, 99 of 316 patients receiving LIB (31.3%) did not require any postoperative opioids compared with 38 of 173 receiving NLIB (22.0%); however, this difference was not statistically significant after adjusting for prior opioid use and preoperative pain (P=.33). No statistically significant differences in postoperative total morphine equivalents or mean daily morphine equivalents consumed between the groups were found during their hospital stays (P>.05 for both). Finally, no significant differences were found in 30- and 90-day ED visits or readmission rates (all P>.05). LIB and NLIB demonstrated differences in patient-reported pain scores at 24 and 36 hours postoperation, although these did not reach clinical significance. There were no statistically significant differences in opioid consumption during the hospital stay, including opioid use, total morphine equivalents, and daily mean morphine equivalents consumed during the hospital stay. Additionally, no differences were observed in 30- and 90-day ED visits or readmission rates.

Does selective intraoperative music reduce pain following abdominal wall reconstruction? A double-blind randomized controlled trial

PurposeAlthough intraoperative music is purported to mitigate postoperative pain after some procedures, its application has never been explored in abdominal wall reconstruction (AWR). We sought to determine whether intraoperative music would decrease early postoperative pain following AWR.MethodsWe conducted a placebo-controlled, patient-, surgeon-, and assessor-blinded, randomized controlled trial at a single center between June 2022 and July 2023 including 321 adult patients undergoing open AWR with retromuscular mesh. Patients received noise-canceling headphones and were randomized 1:1 to patient-selected music or silence after induction, stratified by preoperative chronic opioid use. All patients received multimodal pain control. The primary outcome was pain (NRS-11) at 24 ± 3 h. The primary outcome was analyzed by linear regression with pre-specified covariates (chronic opioid use, hernia width, operative time, myofascial release, anxiety disorder diagnosis, and preoperative STAI-6 score).Results178 patients were randomized to music, 164 of which were analyzed. 177 were randomized to silence, 157 of which were analyzed. At 24 ± 3 h postoperatively, there was no difference in the primary outcome of NRS-11 scores (5.18 ± 2.62 vs 5.27 ± 2.46, p = 0.75). After adjusting for prespecified covariates, the difference of NRS-11 scores at 24 ± 3 h between the music and silence groups remained insignificant (p = 0.83). There was no difference in NRS-11 or STAI-6 scores at 48 ± 3 and 72 ± 3 h, intraoperative sedation, or postoperative narcotic usage.ConclusionFor patients undergoing AWR, there was no benefit of intraoperative music over routine multimodal pain control for early postoperative pain reduction.Trial registrationClinicalTrials.gov: NCT05374096.

Narcotic Consumption Analysis among Severely Injured and Advanced Aged Trauma Patients.

Multimodal pain management has been shown to be effective in treating pain in acutely injured trauma patients. Our community-based, level 1 trauma center previously published in 2022 the efficacy of implementing multimodal pain control (MMPC) protocol in our inpatient trauma population which decreased the use of opioids while maintaining similar pain control. The MMPC group had a trend toward higher age and was significantly less injured. We hypothesize MMPC will reduce opioid consumption in both the advanced aged and more severely injured trauma populations while still providing adequate pain control. Defined by the year of admission, MMPC and physician managed pain control (PMPC) were compared in both advanced age groups and between the severely injured groups. The advanced age group included patients ≥55 years old. The severely injured group included ≥18 years old with ≥15 ISS. Primary outcomes were total opioid utilization per day, calculated in morphine milliequivalents (MME), and median daily pain scores. For the severely injured population, the MMPC group showed a 3-fold decrease in opioid use (30MME/d vs 90.3MME/d, P < .001) and lower pain scores (5/10 vs 6/10, P < .001) than the PMPC group. In the advance age group, there was no significant difference between MMPC and PMPC groups in opioid use (P = .974) or pain scores (P = .553). MMPC effectively reduces opioid consumption in a severely injured patient population while simultaneously improving pain control. Advanced age trauma patients can require complex pain management solutions and future research to determine their needs is recommended.

Impacts of State-Level Opioid Review Programs on Injured Workers and Their Health Care Providers: A Qualitative Study in Washington and Ohio.

Unsafe prescribing practices have been among the central causes of improper reception of opioids, unsafe use, and overdose in the United States. Workers' compensation agencies in Washington and Ohio have implemented opioid review programs (ORPs)-a form of quality improvement based on utilization review-to curb unsafe prescribing. Evidence suggests that such regulations indeed reduce unsafe prescribing, but pharmaceutical companies and patient advocates have raised concerns about negative impacts that could also result. This study explores whether three core sets of problems have actually come to pass: (1) unmanaged pain or reduced function among patients, (2) anger or resistance to ORPs from patients or providers, and (3) damage to patient-provider relationships or clinical autonomy. In-depth semistructured interviews were conducted with 48 patients (21 from Washington, 27 from Ohio) and 32 providers (18 from Washington, 14 from Ohio) who were purposively sampled to represent a range of injury and practice types. Thematic coding was conducted with codebooks developed using both inductive and deductive approaches. The consequences of opioid regulations have been generally positive: providers report more limited prescribing and a focus on multimodal pain control; patients report satisfactory pain control and recovery alongside collaborative relationships with providers. Participants attribute these patterns to a broad environment of opioid caution; they do not generally perceive workers' compensation policies as distinctly impactful. Both patients and providers comment frequently on the difficult aspects of interacting with workers' compensation agencies; effects of these range from simple inconvenience to delays in care, unmanaged pain, and reduced potential for physical recovery. In general, the three types of feared negative impacts have not come to pass for either patients or providers. Although interacting with workers' compensation agencies involves difficulties typical of interacting with other insurers, opioid controls seem to have generally positive effects and are generally perceived of favorably.

Effect of post-operative NSAID use on rotator cuff repair outcomes

BackgroundThe impact of non-steroidal anti-inflammatory drugs (NSAIDs) on rotator cuff repair is an ongoing area of study within orthopedics, with conflicting results in current literature. Despite concerns over the deleterious effects of NSAIDs on rotator cuff healing, they are becoming an integral part of a multimodal post-operative pain control regiment. The purpose of this study was to compare post-operative patient-reported outcomes (PROs), complications rates, and retear rates of arthroscopic rotator cuff repairs in patients using ibuprofen post-operatively to those who abstained from NSAIDs for six weeks after surgery. It was hypothesized that a short course of ibuprofen post-operatively would not lead to inferior PRO scores, increased retear rates, nor increased complication rates after arthroscopic rotator cuff repair. MethodsPatients of the primary surgeon who underwent arthroscopic rotator cuff repair between 2012 and 2022 were evaluated by retrospective chart review. In May 2017 the primary surgeon changed his protocol from avoiding NSAIDs for six weeks after surgery to routinely prescribing two weeks of Ibuprofen 800 mg TID post-operatively. Patients who avoided NSAIDs for six weeks were compared to patients who were prescribed NSAIDs post-operatively. Patient demographic data, pre-operative MRI results, pre-operative and post-operative PROs were collected from the EMR. Additionally, post-operative complications and repair failures requiring reoperation within one year were evaluated. Results125 patients met inclusion criteria for this study with 36 patients in the NSAID group and 89 in the no NSAID group. When comparing improvement in PROs, the NSAID group reached MCID at one year in 83.8 % of patients and the no NSAID group reached MCID at one year in 73.9 % of patients. There was no significant difference between the groups in reaching MCID improvement at one year (p = 0.471). Five post-operative complications were reported in the no NSAID group and two in the NSAID group (5.7 % vs 5.4 %, respectively, p = 0.827). Finally, there was no significant difference in the percentage of post-operative rotator cuff repair failures requiring revision in the first year between the groups (2.3 % vs 2.7 %, p = 1.000). ConclusionThere was no difference in percent of patients improving their PRO by the MCID between the groups that used ibuprofen and the group that did not. There was also no difference in post-operative complication rates and rates of symptomatic retear requiring reoperation between the groups. This supports that a short course of NSAIDs post-operatively, specifically ibuprofen, after rotator cuff repair does not increase reoperation rates nor lead to a clinically significant decrease in PROs at one year.

Cruciate-Retaining Total Knee Arthroplasty versus Unicompartmental Knee Arthroplasty in Medial Compartmental Osteoarthritis: A Propensity Score-Matched Analysis of Early Postoperative Recovery.

Cruciate-retaining (CR) total knee arthroplasty (TKA) may provide better physiological knee kinematics, proprioception, and quadricep recovery than posterior-stabilized (PS) TKA. Therefore, we hypothesized that CR TKA with multimodal pain control may provide comparable postoperative pain and recovery as unicompartmental knee arthroplasty (UKA). This study included patients with isolated medial compartment knee osteoarthritis who underwent CR TKA and UKA. TKA and UKA patients were propensity score-matched with age and body mass index (BMI) and compared using visual analog scales (VAS) for pain scores, total amount of morphine use (TMU), knee flexion angle, straight leg raise (SLR), independent ambulation, length of hospital stay (LOS), and costs during hospitalization. After propensity score matching, 46 patients were included in the TKA and UKA groups, respectively, with no differences in demographic data. VAS at 6-72 h and TMU at 48 h after surgery were comparable between the groups. The knee flexion angle in the UKA group was significantly higher at 24 h (60.0° vs 46.6°; p<0.001) and 48 h (76.9° vs 69.1°; p = 0.021) than that in the TKA group. The SLR in the UKA group was significantly higher than that in the TKA group at 24-72 h. The UKA group ambulated significantly earlier (1.56 vs 2.13 days; p<0.001), had shorter LOS (3.68 vs 4.28 days; p<0.004) and incurred 12.43% lower costs when compared to the TKA group. Patients who underwent CR TKA with multimodal pain management did not experience more postoperative pain or morphine use than those who underwent UKA. However, UKA patients seem to experienced faster recovery and shorter LOS than CR-TKA patients during the early postoperative course. Accordingly, UKA may be considered instead of TKA for patients who are good candidates for UKA and require expedited recovery.

Fluoroscopic Guided Lumbar Erector Spinae (ESP) Field Blocks: A New Technique and Radiographic Analysis

IntroductionLumbar Erector Spinae (ESP) field blocks have become a common postoperative treatment for surgical pain. The use of long-acting medications like liposomal bupivacaine (Exparel) has become a major component of multi-modal postsurgical pain control. Traditionally ESP injections have been performed using ultrasound (U/S) guidance by an anesthesiologist. Spine surgeons have begun to utilize these liposomal injections in their procedures for post-operative pain management. Our study describes a fluoroscopic guided ESP field block technique which provides reproducible muscular coverage and pain control for spine surgery. Material and MethodsSixty patients undergoing single level lumbar fusion were treated preoperatively with bilateral fluoroscopically guided lumbar erector spinae ESP field blocks with liposomal bupivacaine. We looked at two different injection locations involving the ESP or multifidus muscle fascial planes. The injections contained Iohexal, which was used to evaluate the coverage area of the injection. The levels of coverage were recorded, and post-operative pain control was measured immediately, postoperatively, and at 24 hours. ResultsFluoroscopic field blocks at the L3-4 level were found to provide at least four levels of vertebral coverage rostral-caudally in both ESP and MF fascial planes. Pain was well controlled in both injection sites. ConclusionSurgeon-administered fluoroscopic guided ESP field blocks provided a reliable and consistent pattern of coverage with good postoperative pain control. This technique can be easily adopted by spine surgeons.

Enhancing Pain Management for Open Inguinal Hernia Repair With a Novel Long-Acting Bupivacaine Drug Device (Xaracoll®) in Multimodal Pain Control: A Quality Improvement Initiative to Reduce Post-Operative Opioid Prescribing.

Background Xaracoll® is a Food and Drug Administration (FDA) approved Type 1 Bovine collagen-based bupivacaine hydrochloride (HCl) implant developed to provide postoperative pain management for up to 24 hours after open inguinal hernia repair in adults. This retrospective review examinedthe efficacy of Xaracoll® in the management of postoperative pain compared to injectable Bupivacaine. Methods This retrospective study examines 54 patients who underwent unilateral open inguinal hernia repair by a single surgeon over three years. The control group consisted of 36 patients who received injectable Bupivacaine as the local anesthetic. Eighteen patients received the Xaracoll® drug device intra-operatively following the FDA-approved manufacturer's guidelines. Intra-operative analgesics administered and quantified by oral morphine equivalents (OME), opioid administration for pain control postoperatively, opioid prescriptions upon discharge, postoperative pain scores, and turnaround time (TAT) were compared. Results The use of Xaracoll® in inguinal hernia repair is associated with a decrease in the rate of opioid administration in the post-anesthesia care unit (PACU) (22.2% vs. 52.8%; p = 0.043). In addition, patients requiring opioids in the outpatient setting needed significantly less OME in the Xaracoll® group compared to the control group (52.50 vs. 136.15; p < .001). Conclusion This study demonstrates compelling evidence that Xaracoll® is a useful analgesia adjuvant for inguinal hernia repair, significantly reducing the need for opioids in the PACU and decreasing doses of opioid medications upon discharge.Xaracoll® is effective in minimizing postoperative pain and opioid medication dosages upon discharge as part of a multimodal approach to pain and improving patient experience. Further research is warranted to evaluate Xaracoll®'s role in pain control in the PACU and on discharge.

Early pain experiences in dairy calves on pain sensitivity later in life

In humans, early painful experiences can increase pain sensitivity later in life, but little is known regarding this phenomenon in cattle. This study assessed if a painful event early in life affects later pain sensitivity in 40-d-old calves. Holstein calves (n = 26) were randomly assigned to control or treatment conditions, blocked within sex and birth weight. At 9.5 ± 1.8 d old, treatment calves had 1 horn bud disbudded using caustic paste, whereas control calves had 1 horn sham disbudded; in both cases, multimodal pain control was provided. All calves had the contralateral horn bud disbudded using a hot iron 4 wk later, again with multimodal pain control. Mechanical nociceptive responses were assessed weekly using an algometer applied adjacent to both horn buds and on the rump, beginning 3 d before the first disbudding and ending 30 d after the second disbudding. Following the second disbudding, both groups of calves showed evidence of increased sensitivity (i.e., algometer pressure declined 3.69 ± 0.60 √N to 2.13 ± 0.70 √N) on the contralateral bud, but there was no difference between the control group and the treatment groups. An interaction between treatment and time, likely driven by treatment differences, was found on the rump when tested 5 h after the second disbudding event. These responses are not consistent with the hypothesis that an early pain experience results in increased sensitivity to later painful experiences.

Postoperative Complications Associated with Non-Steroidal Anti-Inflammatory Combinations Used Status-Post Total Hip and Knee Arthroplasty.

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in multimodal pain control following total joint arthroplasty (TJA). However, few studies have assessed the complications associated with the combinations of NSAIDs in this population despite the known risks associated with this class of medications. The Premier Healthcare Database was queried to identify adults who underwent primary total hip or knee arthroplasty from 2005-2014. The following most common inpatient combinations of NSAIDs were chosen for analysis: aspirin + celecoxib (A + C), toradol + aspirin (T + A), toradol + ibuprofen (T + I), celecoxib + ibuprofen (C + I), ibuprofen + aspirin (I + A), and toradol + celecoxib (T + C). Primary outcomes included acute kidney injury (AKI), gastrointestinal bleed, and stroke. Secondary outcomes included periprosthetic joint infection (PJI), deep vein thrombosis, and pulmonary embolism. Univariate and multivariate regression analyses were used to compare differences and address confounds. Overall, 195,833 patients were identified. After controlling for confounds, increased odds of AKI was associated with A + C (adjusted odds ratio [aOR]: 1.20, 95% confidence interval [CI]: 1.09-1.34, p < 0.001) and decreased odds was associated with T + A (aOR 0.76, 95% CI: 0.69-0.83, p < 0.001). Increased odds of stroke was associated with A + C (aOR: 1.80, 95% CI: 1.15-2.84, p = 0.011); T + I (aOR 3.48, 95% CI: 1.25-9.73, p = 0.017); and I + A (aOR 4.29, 95% CI: 1.06-17.9, p = 0.046). Increased odds of PJI was associated with C + I (aOR: 10.3, 95% CI: 1.35-78.3, p = 0.024). In the TJA patient population, NSAID pairings should be regarded as distinct entities. Our results suggest that combinations including A + C, T + I, I + A, and C + I should be used cautiously. With this knowledge, providers should consider tailoring NSAID prescriptions appropriately.

Comparison of Erector Spinae Plane Blocks Versus Multimodal Pain Management for Traumatic Rib Fractures: A Matched Cohort Study

IntroductionErector spinae plane blocks (ESPBs) are frequently utilized when treating patients with multiple rib fractures. While previous work has demonstrated the efficacy of ESPB as an adequate method of pain control, there has been no work comparing a continuous ESPB to “best practice” multimodal pain control. We hypothesize that a continuous ESPB catheter combined with a multimodal pain regimen may be associated with a decrease in opioid requirements when compared to a multimodal pain regimen alone. MethodsThis was a retrospective observational cohort study at a level 1 trauma center from September 2016 through September 2021. Inclusion criteria included patients 18 y or older with at least three unilateral rib fractures who were not mechanically ventilated during admission. The primary outcome was the total morphine equivalents utilized throughout the index admission. ResultsA total of 142 patients were included in this study, 71 in each cohort. Patients included had a mean age of 52.5 y, and 18% were female. Demographic data including injury severity score, total number of rib fractures, and length of stay were similar. While there was a trend toward a decrease in morphine equivalents in the patient cohort undergoing ESPB catheter placement, this was not found to be statistically significant (284.3 ± 244.8 versus 412.6 ± 622.2, P = 0.5). ConclusionsWhile ESPB catheters are frequently utilized for analgesia in the setting of multiple rib fractures, there was no decrease in total opioid usage when compared with patients who were managed with a multimodal pain regimen alone. Further assessment comparing ESPB catheters to best practice multimodal pain control regimens through a prospective, multicenter trial is required to further validate these findings.

Erector Spinae versus Surgically Placed Pain Catheters for Thoracic Outlet Decompression

Perioperative care after surgery for thoracic outlet syndrome (TOS) involves multimodal pain control. Pain catheters with bupivacaine infusion are a modality to minimize perioperative narcotic use. Our study aims to compare surgically placed pain catheters (SP) with erector spinae pain catheters (ESP) placed by the anesthesia pain service. Retrospective review of a prospectively maintained surgical TOS database identified patients undergoing transaxillary first rib resection (FRR) who had either SP or ESP placed for pain control. Patients were matched for age and gender. Data collected included demographics, operative details, and perioperative pain medication use. Narcotic pain medication doses were converted to milligram morphine equivalents (MME) for comparison between groups. Pain medications were collected for several time points: intraoperatively, for each post-operative day (POD), and for the entire hospital stay. Eighty-eight total patients were selected for comparison: 44 patients in the SP and ESP groups. Patients in each group did not differ with regards to age, BMI, gender, diagnosis, or comorbidities. There were no differences in preoperative narcotic use, preoperative pain score, or QuickDASH score. All patients underwent FRR. Concurrent cervical rib resection was performed in 6.8% SP and 6.8% ESP patients (p=1.00), pectoralis minor tenotomy in 34.1% SP and 29.5% ESP patients (p=0.65), and venogram in 31.8% SP and 31.8% ESP patients (p=1.00). Mean OR time was 90.0 minutes in SP and 105.3 minute in ESP cases (p=0.15). Mean length of stay was 1.9 days for SP and 1.8 days for ESP patients (p=0.56). There were no significant differences in intraoperative narcotics dosing in MME (SC: 22.1 vs ESP: 25.3, p=0.018). On POD 0, there were no differences in total narcotics dosing (MME) (SC: 112.0 vs ESP: 100.7, p=0.59), or in the use of acetaminophen, NSAIDS, or muscle relaxants. A similar trend in narcotics dosing was observed on POD 1 (SP: 58.6 vs ESP: 69.7, p=0.43), and POD 2 (SP: 23.5 vs ESP: 71.3, p=0.23). On POD 1, there was a higher percentage of SP patients taking NSAIDs (63.6% vs 40.9%, p=0.024), however, this difference was not observed on POD 2. There were no differences in acetaminophen or muscle relaxant use on POD 1 or 2. Total hospital stay MME was similar between groups (SC: 215.9 vs ESP: 250.9, p=0.23) CONCLUSION: Pain catheters with bupivacaine infusions are helpful adjuncts in postoperative pain control after FRR for TOS. This study compares SP to ESP, and demonstrates no difference in narcotics use between SP and ESP groups. SC should be used for pain control in facilities which do not have an anesthesia pain service available for ESP placement.

Adherence to Opioid Prescribing Guidelines in a Statewide Surgical Quality Improvement Collaborative

IntroductionThe opioid crisis is an ongoing crisis in the United States. Postoperative patients who receive opioid prescriptions have a 3%-7% risk of developing a chronic opioid abuse problem. This study aims to describe on-target opioid prescribing and use of multimodal pain management strategies 2 y after the implementation of a multicomponent quality improvement initiative across our statewide collaborative. MethodsFrom July 2020 to September 2021, we prospectively collected data on opioid-prescribing and multimodal strategies for 10 targeted procedures in general, gynecologic, and orthopedic surgery at three hospitals. Prescribing was on-target if a patient was prescribed ≤50 daily morphine milligram equivalents. Multimodal strategies were defined as two or more nonopioid adjuncts used within 48 h of surgery. ResultsOne thousand and eleven targeted procedures were performed with prescription data available for 993 cases. The on-target prescribing rate was 79.6% (n = 790), with general surgery 92.5% (n = 285), gynecology 84.9% (n = 331), and orthopedic surgery 59.0% (n = 174). Patients who received multimodal pain approaches were associated with interventions such as patient education, transversus abdominus plane block, and prescriptions for nonopioid analgesics at discharge. There was no evidence to support a difference in the use of multimodal pain control approaches between patients whose opioid prescribing was on-target or not (73.8% versus 77.3%, P = 0.30). At the first postoperative visit, data on continued opioid use were missing in 57.3% of patients, number of pills used was missing in 93.8%, and adequate pain control was missing in 52.8%. ConclusionsOn-target prescribing and multimodal strategies are common but vary by specialty. Additionally, postoperative pain control and opioid use are often not documented. To better match prescribing to patient needs, understanding patient-level and specialty-level opioid use is important.

Comparison of distal radius fracture plating surgery under wide-awake local anesthesia no tourniquet technique and balanced anesthesia: a retrospective cohort study

BackgroundDistal radius fractures (DRF) are frequently treated with internal fixation under general anesthesia or a brachial plexus block. Recently, the wide-awake local anesthesia with no tourniquet (WALANT) technique has been suggested as a method that results in higher patient satisfaction. This study aimed to evaluate the functional outcomes, complications, and patient-reported outcomes of DRF plating surgery under both the WALANT and balanced anesthesia (BA).MethodsNinety-three patients with DRFs who underwent open reduction and plating were included. Regarding the anesthetic technique, 38 patients received WALANT, while 55 received BA, comprised of multimodal pain control brachial plexus anesthesia with light general support. The patient's overall satisfaction in both groups and the intraoperative numerical rating scale of pain and anxiety (0–10) in the WALANT group were recorded. The peri-operative radiographic parameters were measured; the clinical outcomes, including Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, wrist mobility, and grip strength, were recorded in up to 1-year follow-up. Results presented with a mean difference and 95% confidence intervals and mean ± standard deviation.ResultsThe mean age of patients in the WALANT group was higher than in the BA group (63 ± 17 vs. 54 ± 17, P = 0.005), and there were fewer intra-articular DRF fractures in the WALANT group than in the BA group (AO type A/B/C: 30/3/5 vs. 26/10/19, P = 0.009). The reduction and plating quality were similar in both groups. The clinical outcomes at follow-up were comparable between the two groups, except the WALANT group had worse postoperative 3-month pronation (88% vs. 96%; − 8.0% [ − 15.7 to − 0.2%]) and 6-month pronation (92% vs. 100%; − 9.1% [ − 17.0 to − 1.2%]), and better postoperative 1-year flexion (94% vs. 82%; 12.0% [2.0–22.1%]). The overall satisfaction was comparable in the WALANT and BA groups (8.7 vs. 8.5; 0.2 [ − 0.8 to 1.2]). Patients in the WALANT group reported an injection pain scale of 1.7 ± 2.0, an intraoperative pain scale of 1.2 ± 1.9, and an intraoperative anxiety scale of 2.3 ± 2.8.ConclusionThe reduction quality, functional outcomes, and overall satisfaction were comparable between the WALANT and BA groups. With meticulous preoperative planning, the WALANT technique could be an alternative for DRF plating surgery in selected patients.Trial registration This retrospective study was approved by the Institutional Review Board of Kaohsiung Medical University Hospital (KMUHIRB-E(I)-20210201).

Multimodal postoperative analgesia with transdermal buprenorphine is a safe option in arthroscopic rotator cuff repair.

Arthroscopic rotator cuff repairs are associated with moderate-to-severe pain. Opioids are not the first line for postsurgical pain control due to their potential misuse and side effects. Transdermal buprenorphine represents an alternative for multimodal postoperative pain control. This was a single-centre, prospective longitudinal exploratory study of patients undergoing arthroscopic rotator cuff repairs managed with multimodal analgesia with transdermal buprenorphine. Patients were followed-up by telephone at eight time points, assessing pain levels, rescue analgesics requirement and side effects. Twenty-five patients with an average age of 63.4 ± 8.2 were included. Fourteen patients were ⩾65 years. Pain levels were similar among age groups at all time points, with no pain or mild pain (visual analogue scale 1-4) in most patients. The most frequent side effects were dizziness and somnolence. Transdermal buprenorphine provided a sustained analgesic effect after an arthroscopic rotator cuff repair during the acute postsurgical period. It showed a similar safety profile among younger and older patients.

Erector Spinae Plane Blocks for Circumferential Lumbar Spinal Fusion: Retrospective Cohort Study.

Circumferential lumbar spine fusions are extensive procedures that involve accessing the lumbar spine from multiple approaches. These surgeries often make postoperative pain control challenging, and efforts have been made to find alternative methods of analgesia that do not rely solely on opioids. The use of erector spinae plane (ESP) blocks has been found to be effective in controlling pain while decreasing narcotic requirements in patients undergoing thoracolumbar spine surgery. The purpose of this study is to evaluate the efficacy of ESP blocks for postoperative pain control and its effect on opioid consumption in patients undergoing circumferential lumbar spinal fusion. A retrospective review was performed on patients undergoing 1- or 2-level elective anterior lumbar interbody fusion with open posterior decompression and posterolateral fusion. An analysis was performed to determine the effect of ESP blocks on hospital length of stay (LOS), pain scores using the visual analog scale, and opioid consumption using morphine milligram equivalents. 144 patients were included in the cohort analysis, of whom 36 patients received a preoperative ESP block and 108 did not. Demographic data, comorbidities, and number of levels fused were equally distributed between groups. Patients who received an ESP block had shorter LOS (3.0 vs 4.0 days, P = 0.005) and lower cumulative morphine milligram equivalent in the first 48 hours after surgery (123.7 vs 141.2, P = 0.05). Visual analog scale scores did not significantly differ between patients group except for on postoperative day 4 and at 12-month follow-up. The use of ESP blocks for patients undergoing 1- or 2-level circumferential fusion via an anterior lumbar interbody fusion with concomitant posterior open procedures was associated with decreased postoperative inpatient opioid requirements and LOS. This cohort study supports the growing body of evidence that ESP blocks are a useful adjunct for multimodal pain control. 3 CLINICAL RELEVANCE: The data and results of this study provide clinical evidence supporting the use of ESP blocks in patients undergoing circumferential lumbar spine fusion procedures.
