Correlation between severity of preoperative low back pain and postoperative outcomes in lumbar disc herniation surgery: a retrospective cohort study

BACKGROUND CONTEXTLow back pain (LBP) frequently occurs in patients with lumbar disc herniation (LDH), however the extent to which discectomy ameliorates it and how preoperative LBP influences postoperative outcomes remains unclear. PURPOSETo evaluate the improvement in LBP and its impact on postoperative patient-reported outcome measures (PROMs). STUDY DESIGN/SETTINGMulticenter retrospective observational study. PATIENT SAMPLEPatients undergoing discectomy for LDH at 8 hospitals from April 2017 to March 2021. OUTCOME MEASURESData were collected on patients’ backgrounds, operative factors, and PROMs, including the Numeric Rating Scale (NRS) for pain in the low back, buttock, or leg, EuroQol 5 Dimension (EQ-5D), Oswestry Disability Index (ODI) scores, and postoperative satisfaction. METHODSPatients were categorized into mild (NRS 0–3), moderate (NRS 4–7), or severe (NRS 8–10) LBP groups. Inverse probability weighting with propensity scores was used to adjust for demographic and clinical differences between groups. Chi-square tests and one-way analysis of variance were conducted to compare background data and clinical characteristics. Additionally, multivariate logistic regression was performed to identify risk factors for less than 50% improvement in LBP. RESULTSThis study included 928 patients: 270 mild, 343 moderate, and 315 severe. After adjustment, preoperative NRS scores were significantly different across groups, with scores of 1.6 (SD 1.3), 5.6 (SD 1.0), and 8.8 (SD 0.9), respectively. Postoperative NRS scores also varied significantly, with worse outcomes observed in the severe group compared to the mild group, yet similar to the moderate group. A total of 46.8% of the mild group, 86.6% of the moderate group, and 72.9% of the severe group achieved a 50% decrease in NRS scores of LBP. Preoperative EQ-5D and ODI scores were significantly worse in the severe group compared to the mild or moderate groups, but postoperative scores were not significantly different between the severe and moderate groups. No significant differences in postoperative satisfaction were observed among the groups. Being female was a significant risk factor for less than 50% improvement in LBP (odds ratio = 1.56, p=.022). CONCLUSIONSDiscectomy significantly improved LBP in patients with LDH, including those with moderate or severe LBP. Patients with severe LBP showed similar improvements in PROMs as those with moderate LBP. Female gender emerged as a significant risk factor for less than optimal improvement in LBP.

Effect of pericapsular nerve block on the quality of recovery after shoulder arthroscopy.

Shoulder arthroscopy, a standard orthopedic procedure, often results in severe postoperative pain, leading to high opioid consumption and delayed recovery. Various analgesic methods, including peripheral nerve blocks, manage this pain. The pericapsular nerve group block is a relatively new technique whose efficacy in shoulder surgeries has yet to be extensively studied. This study aimed to assess the impact of the pericapsular nerve group block on postoperative recovery quality following shoulder arthroscopy, as measured by the Quality of Recovery-15 score. A randomized, prospective, controlled, multicenter study was conducted with 60 patients undergoing unilateral shoulder arthroscopy. Participants were allocated to either Group P (patients receiving the pericapsular nerve group block and multimodal analgesia) or Group C (patients receiving only multimodal analgesia). The primary outcome measured was the Quality of Recovery-15 score 24 hours post-surgery. Secondary outcomes included postoperative numeric rating scale scores, the requirement for rescue analgesia, time to first rescue analgesia, postoperative complications, the necessity for antiemetics, and patient satisfaction. The median Quality of Recovery-15 score was significantly higher in Group P compared to Group C (120±10 vs. 89±11; P<0.001). Additionally, Group P exhibited lower pain scores at rest and during movement, a decreased need for rescue analgesia, and an extended duration before the first rescue analgesia was required. Postoperative nausea and vomiting were less common in Group P, and patient satisfaction scores were notably higher in this group. The pericapsular nerve group block significantly enhances postoperative recovery quality, reduces pain and opioid consumption, and improves patient satisfaction without significant complications.

The effect of sacral erector spinae plane block on the quality of recovery after total hip arthroplasty: a prospective, randomized, controlled, multicenter study.

Total hip arthroplasty, commonly performed to alleviate hip pain and enhance functionality in elderly patients, requires effective postoperative pain management to reduce opioid consumption and its associated side effects. A novel regional anaesthesia technique, the sacral erector spinae plane block, has the potential to enhance the quality of postoperative recovery significantly. This prospective, randomized, controlled multicenter study investigated the effects of the sacral erector spinae plane block on recovery quality in patients undergoing total hip arthroplasty. The study comprised 50 patients, divided into Group S (patients receiving patients receiving sacral erector spinae plane block [S-ESPB]) and Group C (patients getting just multimodal analgesia). The primary outcome measured was the Quality of Recovery-15 score 24 hours post-surgery. Secondary outcomes included postoperative numerical rating scale scores (A score of 0 indicates no pain, while 10 indicates the most severe pain), total consumption of rescue analgesics, time to first rescue analgesic administration, patient satisfaction, time to first ambulation, the occurrence of complications, and the need for antiemetics. Group S had markedly higher quality of recovery-15 scores compared to Group C (Group S: median 117 percentiles [97-121]; Group C: median 89 percentiles [75-96]; P<0.001). Group S scored higher in postoperative pain, physical comfort, support, emotional state, and general quality of recovery-15 (P<0.001). Nevertheless, the physical independence category ratings were comparable across both groups (P=0.286). Sacral erector spinae plane block is a promising analgesic technique that enhances postoperative recovery and patient comfort in total hip arthroplasty.

Effectiveness of tramadol-including multimodal analgesia in spinal surgery: a single-center, retrospective cohort study

BackgroundMultimodal analgesia (MMA) is recommended for postoperative pain management; however, studies evaluating the effect of tramadol-including MMA on numerical rating scale (NRS)-based postoperative pain levels and the length of stay (LOS) in the hospital are limited. Therefore, this study aimed to compare the before and after effects of tramadol-including MMA application, and assess its effect on postoperative NRS scores and LOS.MethodsPatients who underwent spinal surgery under general anesthesia at the Rakuwakai Marutamachi Hospital in fiscal years 2020 and 2022 were included in this study. The outcomes between the pre- and post-intervention groups were compared through propensity score matching.ResultsFollowing propensity score matching, 249 patients were included in each group. MMA application significantly decreased the median LOS from 10 to 9 days (p < 0.001). Additionally, the median NRS scores exhibited a significant decrease from 4 to 3 on postoperative day (POD) 3 (p = 0.0109) and from 3 to 2 on POD 5 (p = 0.0087). Following MMA application, the number of patients receiving additional analgesics decreased significantly, from 38 to 6 (p < 0.001).ConclusionsThe introduction of tramadol-including MMA can effectively reduce postoperative pain and decrease the LOS for patients undergoing spinal surgery.

Clinical efficacy of unilateral laminotomy for bilateral decompression in the treatment of adjacent segment disease after lumbar fusion.

To assess the clinical impact of unilateral laminotomy for bilateral decompression (ULBD) in managing patients with adjacent vertebrae following lumbar fusion. A retrospective analysis was conducted on 21 patients, with a mean age of 67.4 years, who underwent ULBD for adjacent vertebra disease at our department from January 2021 to November 2023. We reviewed demographic data, surgical techniques, imaging studies, and patient-reported outcomes. The study compared Visual Analog Scale (VAS) scores, Numeric Rating Scale (NRS) scores, Japanese Orthopaedic Association (JOA) scores, Short Form-36 (SF-36) scores, and imaging outcomes before surgery, immediately post-surgery, and at 1 month, 6 months, and 12 months post-surgery. Evaluation of 21 patients with adjacent segment disease (ASD) (13 males, 8 females; mean age 67.42 years) was performed with follow-ups at various intervals post-surgery. Postoperative VAS, NRS, JOA, and SF-36 scores showed significant improvements compared to preoperative scores. Immediately after surgery, there were significant improvements in NRS score (2.76 ± 0.70 vs. 3.71 ± 0.85, P < 0.05) and JOA score (15.38 ± 1.02 vs. 9.29 ± 1.01, P < 0.05) compared to preoperative scores. Similarly, at 12 months post-surgery, significant improvements were observed in NRS score (1.52 ± 0.51 vs. 3.71 ± 0.85, P < 0.05) and JOA score (25.0 ± 1.10 vs. 9.29 ± 1.01, P < 0.05) compared to preoperative scores. The clinical satisfaction rate was 95.0% among all patients, with postoperative imaging examinations revealing a significant decompression effect. No complications were reported among the surgical patients. This study suggests that endoscopic ULBD can be a safe and effective technique for managing symptomatic ASD, providing satisfactory clinical outcomes for patients with ASD. Endoscopic ULBD may serve as an alternative treatment option for ASD with lumbar stenosis.

Assessing the Efficacy of Thoracic Erector Spinae Plane Block for Postoperative Analgesia in Lumbosacral Spine Surgery: A Prospective Quasi-experimental Study.

Background and aims Optimal postoperative care and analgesia are the key factors in the management of cases of lumbosacral spine surgery. The erector spinae plane (ESP) block is a recently evolving entity and has a dynamic role in postoperative pain management. However, its role in the management of pain in lumber spinal surgeries is still not clear, and the literature remains anecdotal. Therefore, we planned to study the efficacy of ultrasound-guided preoperative ESP block at the T12 level using levobupivacaine for perioperative analgesia in lumbosacral spine surgeries. Methods A total of 60 patients scheduled for elective or emergency lumbosacral spine surgery were divided into two groups - the GA group received standard general anesthesia (GA)and the GA+ESP group received standard general anesthesia along with ultra-sound guided ESP block at the T12 level with a bilateral injection of20 ml 0.25% levobupivacaine. Perioperative analgesia was assessed by total intra-operative fentanyl dose and frequency, intra-operative hemodynamic parameters, post-operative numeric rating scale (NRS) scores, time of first systemic rescue analgesia, tramadol usage, mobilization day, and hospital stay duration. Results Intraoperative fentanyl sparing was observed in 83% of the GA+ESP group compared to 33% in the GA group. Postoperative tramadol sparing was observed in 80% of the GA+ESP group compared to 26.7% of the GA group. Twenty-four-hour postoperative NRS scores >3/10 were observed in 20% of the GA+ ESP group compared to 73.3% of the GA group. Conclusion In this study, superior perioperative analgesia, opioid-sparing effect, and decreased requirement of postoperative rescue analgesia were observed with ESP block.

Cordotomy for pain control and opioid reduction in cancer patients: A cancer center 11-year experience

BackgroundPercutaneous lateral cervical cordotomy (PLCC) is a treatment option for predominantly nociceptive pain of oncological origin that is refractory to conservative methods, with unilateral distribution, particularly in the lower trunk or lower limbs of patients with a life expectancy of less than one year. ObjectiveThe aim of this study was to assess the analgesic efficacy and opioid utilization alteration in patients undergoing PLCC. MethodsWe retrospectively collected data from patients undergoing PLCC between 2011 and 2021 at the AC Camargo Cancer Center in São Paulo, Brazil. ResultsSixty-three patients and their respective surgical outcomes were analyzed. The mean preoperative pain intensity, as assessed by the mean numerical rating scale (NRS), was 8.4 (range: 4–10), while postoperatively, it decreased to 0.78 (range: 0–8). Lower postoperative NRS scores were observed for pain in the lower limbs and abdomen compared to the lower thorax. The mean preoperative oral morphine equivalent (OME) consumption was 231.0 mg (range: 30.0–1015.2). At 30 days postoperative, the mean consumption of OME was 120.2 mg (range: 0.0–705.0). Twelve months after surgery, the average consumption of OME was 98.3 mg (range: 0.0–396.0). ConclusionPLCC is a valuable therapeutic intervention for patients experiencing cancer pain that is unresponsive to conservative treatments. The anticipated analgesic outcomes are generally favorable, particularly in cases where the pain is localized unilaterally in the abdomen or lower body segments.

Peri-Operative Use of Ketamine Infusion versus Dexmedetomidine Infusion for Analgesia in Obese Patients Undergoing Bariatric Surgery: A Double-Blinded Three-Armed Randomized Controlled Trial

Abstract Background The development of different techniques in bariatric surgeries has required the development of novel anesthetic techniques to reduce the incidence of complications and improve post-operative patient outcomes. Ketamine and dexmedetomidine have been used for their peri-operative analgesic profiles in different studies. Methods Ninety patients were studied and randomized equally into three groups. The Ketamine group received a bolus dose (0.3 mg/kg) of ketamine over 10 min followed by an infusion (0.3 mg/kg/h). The Dexmedetomidine group received a bolus dose (0.5 mcg/kg) of dexmedetomidine over 10 min followed by an infusion (0.5 mcg/kg/h). The control group received normal saline infusion. The total morphine dose was the primary outcome, and intra-operative fentanyl requirements, time to extubation, post-operative nausea and vomiting (PONV), Numerical Rating Scale (NRS) scores, and Modified Observer’s Agitation/Sedation Scale (MOASS) scores were secondary outcomes of the study. Results The Dexmedetomidine group showed decreased intra-operative fentanyl requirements (160.000 ± 42.345 µcg), less time to extubation (3.700 ± 0.925 min), and better scores on MOASS than the other groups. Post-operative NRS scores and the morphine requirement in the Ketamine group (1.867 ± 2.921 mg) were lower than in the other groups. The Dexmedetomidine group showed the lowest scores for PONV. Conclusions The Dexmedetomidine group showed lower total fentanyl doses, a significantly shorter time to extubation, better MOASS scores, and lower PONV. The Ketamine group showed significantly lower NRS scores and morphine doses than the other two groups. Dexmedetomidine was effective on the reduction of intraoperative fentanyl requirement with early extubation, and ketamine was effective on the reduction of postoperative pain. Trial Registration This trial has been registered on clinicaltrials.gov registry (NCT04576975) since 06/10/2020.

Comparison of the effects of sciatic nerve block combined with continuted femoral nerve block or continuted adductor canal block on pain and motor function after total knee arthroplasty

To compare the effect of sciatic nerve block (SNB) combined with continuted femoral nerve block (FNB) or continuted adductor canal block (ACB) on pain and motor function after total knee arthroplasty (TKA). A total of 60 patients with TKA-treated osteoarthritis of the knee who met the selection criteria were enrolled between November 2020 and February 2021 and randomised allocated into the study group (SNB combined with continuted ACB) and the control group (SNB combined with continuted FNB), with 30 cases in each group. There was no significant difference in gender, age, body mass, height, body mass index, preoperative Hospital for Special Surgery (HSS) score, femoral tibial angle, and medial proximal tibial angle between the two groups ( P>0.05). The operation time, the initial time to the ground, the initial walking distance, and the postoperative hospital stay were recorded. At 2, 4, 6, 12, 24, and 48 hours after operation, the numerical rating scale (NRS) score was used to evaluate the rest pain around the knee joint, the quadriceps femoris muscle strength was evaluated by the freehand muscle strength method, and the knee flexion and extension angles were measured. There was no significant difference in the operation time and initial walking distance between the two groups ( P>0.05); the initial time to the ground and postoperative hospital stay of the study group were significantly shorter than those of the control group ( P<0.05). Except for the 48-hour postoperative NRS score of the study group, which was significantly lower than that of the control group ( P<0.05), there was no significant difference in the NRS scores between the two groups at the remaining time points ( P>0.05). The quadriceps femoris muscle strength from 4 to 24 hours postoperatively and the knee extension angle from 2 to 6 hours postoperatively of the study group were significantly better than those of the control group ( P<0.05); the differences in the quadriceps femoris muscle strength and knee extension and flexion angles between the two groups at the remaining time points were not significant ( P>0.05). SNB combined with either continuted ACB or continuted FNB can effectively relieve pain in patients after TKA, and compared with combined continuted FNB, combined continuted ACB has less effect on quadriceps femoris muscle strength, and patients have better recovery of knee flexion and extension mobility.

Erector spinae plane block level does not impact analgesic efficacy in enhanced recovery for lumbar spine surgery

BACKGROUND CONTEXTPostoperative pain control following spine surgery can be difficult. The Enhanced Recovery After Surgery (ERAS) programs use multimodal approaches to manage postoperative pain. While an erector spinae plane block (ESPB) is commonly utilized, the ideal distance for injection from the incision, referred to as the ES (ESPB to mid-surgical level) distance, remains undetermined. PURPOSEWe evaluated the impact of varying ES distances for ESPB on Numerical Rating Scale (NRS) measures of postoperative pain within the ERAS protocol. STUDY DESIGN/SETTINGRetrospective observational study. PATIENT SAMPLEAdult patients who underwent elective lumbar spine fusion surgery. OUTCOME MEASURESPrimary outcome measures include the comparative postoperative NRS scores across groups at immediate (T1), 24 (T2), 48 (T3), and 72 (T4) hours postsurgery. For secondary outcomes, a propensity matching analysis compared these outcomes between the ERAS and non-ERAS groups, with opioid-related recovery metrics also assessed. METHODSAll included patients were assigned to one of three ERAS groups according to the ES distance: Group 1 (G1, ES > 3 segments), Group 2 (G2, ES = 2–3 segments), and Group 3 (G3, ES<2 segments). Each patient underwent a bilateral ultrasound-guided ESPB with 60 mL of diluted ropivacaine or bupivacaine. RESULTSPatients within the ERAS cohort reported mild pain (NRS < 3), with no significant NRS variation across G1 to G3 at any time. Sixty-five patients were matched across ERAS and non-ERAS groups. The ERAS group exhibited significantly lower NRS scores from T1 to T3 than the non-ERAS group. Total morphine consumption during hospitalization was 26.7 mg for ERAS and 41.5 mg for non-ERAS patients. The ERAS group resumed water and food intake sooner and had less postoperative nausea and vomiting. CONCLUSIONSESPBs can be effectively administered at or near the mid-surgical level to the low thoracic region for lumbar spine surgeries. Given challenges with sonovisualization, a lumbar ESPB may be preferred to minimize the risk of inadvertent pleural injury.

Predictors for Failure to Respond to Erector Spinae Plane Block Following Minimally Invasive Transforaminal Lumbar Interbody Fusion.

Retrospective review of prospectively collected data. To identify the risk factors associated with failure to respond to erector spinae plane (ESP) block following minimally invasive transforaminal lumbar interbody fusion (MI-TLIF). ESP block is an emerging opioid-sparing regional anesthetic that has been shown to reduce immediate postoperative pain and opioid demand following MI-TLIF-however, not all patients who receive ESP blocks perioperatively experience a reduction in immediate postoperative pain. This was a retrospective review of consecutive patients undergoing one-level MI-TLIF who received ESP blocks by a single anesthesiologist perioperatively at a single institution. ESP blocks were administered in the OR following induction. Failure to respond to ESP block was defined as patients with a first numerical rating scale (NRS) score postsurgery of >5.7 (mean immediate postoperative NRS score of control cohort undergoing MI TLIF without ESP block). Multivariable logistic regressions were performed to identify predictors for failure to respond to ESP block. A total of 134 patients were included (mean age 60.6 yr, 43.3% females). The median and interquartile range (IQR) first pain score postsurgery was 2.5 (0.0-7.5). Forty-nine (36.6%) patients failed to respond to ESP block. In the multivariable regression analysis, several independent predictors for failure to respond to ESP block following MI TLIF were identified: female sex (OR 2.33, 95% CI 1.04-5.98, P =0.040), preoperative opioid use (OR 2.75, 95% CI 1.03-7.30, P =0.043), anxiety requiring medication (OR 3.83, 95% CI 1.27-11.49, P =0.017), and hyperlipidemia (OR 3.15, 95% CI 1.31-7.55, P =0.010). Our study identified several predictors for failure to respond to ESP block following MI TLIF, including female gender, preoperative opioid pain medication use, anxiety, and hyperlipidemia. These findings may help inform the approach to counseling patients on perioperative outcomes and pain expectations following MI-TLIF with ESP block. 3.

A new surgical method to treat intracanal lumbar disc herniation using the unilateral biportal endoscopic transforaminal approach: patient series.

Unilateral biportal endoscopic lumbar discectomy (UBELD) is a new minimally invasive spine surgery. The purpose of this study is to describe a new surgical method to treat intracanal lumbar disc herniation (LDH) using the unilateral biportal endoscopic transforaminal approach (UBE-TFA). The first 15 patients who had undergone UBELD for single-level LDH were included in this study. Operative time, intraoperative blood loss, postoperative stay, and intraoperative complications were recorded. The Oswestry Disability Index (ODI), numeric rating scale (NRS) score for leg pain, and modified MacNab criteria were assessed at 3 months postoperatively. The mean operative time was 52.0 ± 13.8 minutes. The mean intraoperative blood loss was 10.5 ± 10.2 mL. The mean postoperative stay was 1.1 ± 0.3 days. There were no complications. The postoperative mean ODI was significantly improved from 44.9 ± 14.4 to 7.7 ± 11.2 at the final follow-up (p < 0.001). There was a significant decrease in the postoperative mean NRS score for leg pain, from 6.1 ± 1.9 to 0.8 ± 1.3 at the final follow-up (p < 0.001). Based on the modified MacNab criteria, good to excellent results were obtained in 86.7% of the patients. We considered UBELD-TFA as not only one of the promising surgical methods for UBELD, but also a new surgical implementation of the TFA.

Efficacy of Gasserian Ganglion High‐Voltage, Long‐Duration Pulsed Radiofrequency Combined With Block on Acute/Subacute Zoster‐Related Trigeminal Neuralgia

Background: Trigeminal postherpetic neuralgia (TPHN) is a severe chronic pain that can lead to various socioeconomic consequences. Therefore, it is necessary to explore optimal treatment options for acute/subacute herpes zoster (HZ)–related trigeminal neuralgia and prevent the further development of TPHN. High‐voltage, long‐duration pulsed radiofrequency (HL‐PRF) of the Gasserian ganglion is a new surgical intervention used to treat PHN. A ganglion block has been reported to possess anti‐inflammatory effects and potential analgesic benefits.Methods: We included 83 patients with HZ‐related acute/subacute trigeminal neuralgia admitted from January 1, 2021, to June 1, 2023, and received Gasserian ganglion HL‐PRF combined with block. A 6‐month follow‐up was conducted, including Numerical Rating Scale (NRS) scores, Pittsburgh Sleep Quality Index (PSQI), the incidence of TPHN, the dosage of anticonvulsants and analgesics, efficacy, and adverse events.Results: All patients showed a significant decrease in postoperative NRS scores (p &lt; 0.05). The NRS scores of the acute HZ group were consistently lower than those of the subacute HZ group at different time points (p &lt; 0.01). The overall incidence of TPHN from the onset of HZ to 12 weeks is 21.68%. The incidence of TPHN in the acute phase group was 12.77%, significantly lower than the 33.33% in the subacute phase group (p = 0.024). The effective rate was 74.7% in all patients, at 3 months after the treatment. The effective rate was 82.98% in the acute phase group and 63.89% in the subacute phase group, showing a statistically significant difference (p = 0.047). The PSQI score of the acute group was consistently lower than that of the subacute group (p &lt; 0.01). The dosage of analgesics and anticonvulsants used in the acute HZ group was lower than that in the subacute group (p &lt; 0.01). All patients did not experience serious adverse reactions.Conclusions: Gasserian ganglion HL‐PRF combined with block can be an effective and safe technique to relieve the pain of acute/subacute zoster‐related trigeminal neuralgia and prevent the incidence of TPHN.

Low central sensitisation inventory score is associated with better post-operative outcomes of osteotomy around the knee.

The purpose of this study was to investigate the potential association between central sensitisation inventory (CSI) scores and post-operative patient-reported outcomes (PROs) in patients underwent osteotomy around the knee (OAK), with a CSI cut-off score specific for knee osteoarthritis. CSI scores were collected from 173 patients who underwent OAK, along with their knee injury and osteoarthritis outcome score (KOOS) and pain numeric rating scale (NRS) scores. Patients were divided into high-CSI score group and low-CSI score group with a cut-off score of 17. Multivariate linear regression was performed to test the association between CSI scores and post-operative outcomes. Pre-surgery KOOS and NRS scores and the rate of attainment of minimal clinically important difference (MCID) of KOOS scores was analysed as secondary outcomes. Low-CSI score group had significantly higher post-operative KOOS scores and lower pain NRS scores compared to the high-CSI score group (< p = 0.01) after adjusting for confounding factors. For pre-operative scores, only the KOOS-Symptom score was significantly different between the groups (64.7 ± 20.1 when CSI < 17 vs.55.1 ± 19.7 when CSI ≥ 17; p = 0.008). The low-CSI score group had significantly higher MCID achievement rates of KOOS-Pain, Symptom, and ADL than the high-CSI score group (86% vs. 68%; 74% vs. 55%; 86% vs. 67%, respectively; P < 0.05). This study established an association between post-operative CSI scores ≥ 17 and poorer outcomes following OAK, highlighting the potential value of the CSI in identifying patients in need of more comprehensive peri-operative pain management. Level III. Retrospective comparative study.

Effect of peripheral nerve block versus general anesthesia on the hemodynamics and prognosis of diabetic patients undergoing diabetic foot Surgery

BackgroundDiabetic foot ulcers (DFUs) represent a significant foot-related concern for patients with multiple co-morbidities, and surgical intervention is often employed. Notably, peripheral nerve block anesthesia (PNB) has emerged as a new approach for the surgical management of DFUs, providing sustained hemodynamic stability and superior postoperative pain control compared to general anesthesia (GEA).MethodsThe present study utilized a retrospective analysis of hospitalized patients who met the inclusion criteria for DFUs over a period of 7 years. Patients were categorized into two groups based on the type of anesthesia employed during the procedure: GEA or PNB. Extensive patient information was gathered and analyzed, such as demographics, intraoperative hemodynamic parameters, numeric rating scale (NRS) scores, and healing outcomes. The preliminary results assessed in this study were intraoperative hemodynamic stability and postoperative analgesic efficacy.ResultsDuring the study period, 117 patients received surgical therapy based on GEA, while 145 patients received PNB. Notably, the mean intraoperative blood pressure was significantly lower in the GEA group, and this difference remained statistically significant even after Bonferroni adjustment using linear mixed models. Additionally, the frequency of hypotensive episodes was higher in the GEA group (P < 0.05). Furthermore, the perioperative transfusion volume, overall intraoperative fluid input, and intraoperative bleeding volume were significantly more significant in the GEA group than in the PNB group. The postoperative pain NRS scores differed considerably between the two groups (Bonferroni corrected P < 0.01), with the GEA group exhibiting higher opioid consumption on the day of surgery and the first postoperative day when using patient-controlled intravenous analgesia (PCIA). Supplemental analgesic medication was more significant in the GEA group 24 h postoperatively. However, the two groups had no difference in hospital stay or treatment outcomes. There was no difference between the two groups regarding secondary surgery and amputation procedures. Although the 5-year mortality rate is 30.5%, no significant difference in mortality rates between the two groups was observed.ConclusionsCompared to GEA, PNB is a safe and effective alternative therapy for managing DFUs. Our findings suggest that PNB administration during surgical intervention for this condition results in more stable intraoperative hemodynamics and superior postoperative analgesic effects, despite no significant difference in overall treatment outcomes between the two groups. The two groups did not differ in re-surgery, amputation, or 5-year mortality.

Return to work status of patients under 65 years of age with osteonecrosis of the femoral head after total hip arthroplasty

ObjectiveThis aimed to evaluate the status of return to work (RTW) in patients with osteonecrosis of the femoral head (ONFH) after total hip arthroplasty (THA).MethodsThe baseline characteristics of all patients in this retrospective study were obtained from the hospital patient database. The relevant changes in patients' working conditions, as well as the numerical rating scale (NRS), Harris Hip Score (HHS), self-assessment of work ability, and Likert scale satisfaction assessment were obtained through video call follow-ups.Results118 patients (response rate: 83%) were ultimately included in this study. The average length of time for the patients to stop working preoperatively was 20.7 weeks. Ninety-four patients (24 women and 70 men) who underwent THA had RTW status, with a mean RTW time of 21.0 weeks. Men had a significantly higher proportion of final RTW and a significantly faster RTW than women. Significant differences in smoking, drinking, cardiovascular diseases, changes in working levels, variations in the types of physical work, changes in working hours, and pain symptoms were observed between the RTW and Non-RTW populations. The patients with a positive RTW status had higher postoperative HHS scores, lower postoperative NRS scores, and higher self-assessment of work ability than patients who had a negative RTW status.ConclusionUltimately, 80% of patients achieved RTW status. Drinking, sex, change in working level, variation in the type of physical work, change in working hours, post-surgery HHS score and self-assessment of work ability can serve as predictive factors for RTW.

Combined multiple regional anesthesia for microwave ablation of liver Tumors: Initial experience

ObjectiveThis study aims to assess the feasibility and safety of combined multiple regional anesthesia (CMRA) as a potential strategy to decrease pain and reliance on intravenous analgesics during and after ultrasound-guided microwave ablation (US-guided-MWA) of liver tumors. MethodsA cohort of 75 patients with a total of 99 liver tumors who underwent US-guided-MWA of liver tumors were enrolled. These patients were randomly allocated into three groups: A, B, and C. Prior to the ablation procedure, Group A patients received a combination of hepatic hilar block (HHB), Transversus abdominis plane block (TAPB), and local anesthesia (LA). Patients in Group B were administered HHB in conjunction with LA, while those in Group C received TAPB and LA. Evaluative parameters included the Numerical Rating Scale (NRS) scores, consumption of morphine, incidence of complications, and factors influencing perioperative pain. ResultsAll patients successfully underwent US-guided-MWA. The peak NRS scores for pain during ablation across the three groups were 2.36 ± 1.19, 3.28 ± 1.59, and 4.24 ± 1.42 respectively (P < 0.01), while the count of patients requiring morphine were 4/25, 8/25, and 13/25 respectively (P < 0.01). Postoperative NRS scores for the three groups at 4, 8, 12, 24, and 36-hour intervals demonstrated a pattern of initial increase followed by a decrease, with the order at each interval being: Group A < Group C < Group B. Factors associated with increased pain included larger tumor size, greater number of tumors, and longer procedure and ablation time (P < 0.05). No major complications were recorded across the three groups. ConclusionCMRA offers an effective and safe modality to manage pain during and after US-guided-MWA of liver tumors.

The AMADEUS score is not a sufficient predictor for functional outcome after autologous chondrocyte implantation (ACI) of the knee: data from the German Cartilage Registry (KnorpelRegister DGOU)

IntroductionThe AMADEUS (Area Measurement And DEpth and Underlying Structures) score has advanced to a commonly used tool for MRI-based chondral defect severity grading prior to cartilage knee surgery. It was the intention of this study to assess the AMADEUS for a potential correlation with clinical data by patient-reported outcome measures (PROMs).MethodsA total of 51 patients undergoing ACI (autologous chondrocyte implantation) between 2016 and 2022 were found eligible and retrospectively analyzed. All patients were registered in the German Cartilage Registry prior to surgery and follow-up data were collected using the Knee Osteoarthritis Outcome score (KOOS), the International Knee Documentation Committee (IKDC) Form and the numeric rating scale (NRS). Pre-operative MRI images were scored by three raters using the AMADEUS classification system, and an overall AMADEUS score was calculated which was subsequently correlated with pre- and post-operative PROMs.ResultsMean patient age was 32.67 ± 8.37 years and mean defect size area 343.04 mm2 ± 139.45 mm2. No correlative capacity of the pre- and postoperative IKDC, KOOS or NRS scores was found with the AMADEUS final score or any of its subscores. From the pre- to postoperative visit, a significant improvement of the PROMs (IKDC: 45.53 ± 21.00 vs. 59.83 ± 17.93, p = 0.04; KOOS Pain: 58.00 ± 16.70 vs. 76.06 ± 19.20, p = 0.03; KOOS ADL: 64.17 ± 18.76 vs. 82.11 ± 16.68, p < 0.01; KOOS Sports: 26.11 ± 18.52 vs. 50.56 ± 23.94, p = 0.01; KOOS QOL: 25.50 ± 14.26 ± 45.28 ± 19.03, p = 0.00) was found. Intraclass correlation coefficients showed an overall good interrater agreement for the AMADEUS total score (ICC = 0.75).ConclusionsStudy results suggest no correlative capacity of the AMADEUS with routinely used PROMs in patients undergoing ACI. Therefore, radiographically assessed cartilage defect characteristics poorly translate to pre- and postoperative patient-reported outcome data.

Nomogram for Predicting the Recurrence Rate in Selective Radiofrequency Thermocoagulation of the Trigeminal Nerve Based on Regression via Least Absolute Shrinkage and Selection Operator

BACKGROUND: Computed tomography-guided percutaneous selective radiofrequency thermocoagulation (RFT) of the trigeminal nerve is a novel, minimally invasive technique for the treatment of trigeminal neuralgia, but the high recurrence rate after surgery might pose a serious problem. OBJECTIVES: The purpose of this study was to explore the risk factors affecting the recurrence rate after RFT and to predict the recurrence rate and provide evidence for the early prediction. STUDY DESIGN: A single-center retrospective study. SETTING: This study was carried out in the Affiliated Hospital of Jiaxing University in China. METHODS: One hundred thirty-nine patients were included in this study. The cumulative survival rates according to temperature and type of pain were estimated by the Kaplan-Meier analysis. The least absolute shrinkage and selection operator Cox regression model was used to build the nomogram. Time-independent receiver operating characteristic curve analysis confirmed the signature’s predictive capacity. A calibration curve was generated to judge the accuracy of absolute risk predictions, and Brier scores were used to quantitatively evaluate the calibration. Decision curve analysis was applied to comprehensively evaluate the clinical effectiveness of the model. A multiparameter nomogram was used to analyze the scores and predict the risk of relapse. RESULTS: Three predictors were screened by multivariate Cox regression analysis. Pain grade (refit hazard ratio [HR]: 1.6807; 95% confidence interval [CI]: 1.1963-2.3613) and type of pain (HR: 6.2802; 95% CI: 3.3705-11.7021) were considered to be risk factors affecting the recurrence rate after RFT, while temperature (HR: 0.5203; 95% CI: 0.2859-0.9468) was identified as a protective factor. The recurrence rate within 2 years in 85°C group was 51.09%, while that in 95°C group was 29.79%. The nomogram exhibited good discrimination and calibration. Compared with the preoperative period, all of the patients’ postoperative Numeric Rating Scale scores (NRS-11)decreased significantly (P &lt; 0.05). The main postoperative complication was numbness, with a gradual decrease in the Barrow Neurological Institute score over time. Autonomic symptoms and decrease of masticatory muscle function were the secondary postoperative complications, and no other adverse events were observed. Overall patient satisfaction at 2 years postoperatively was 7.83 ± 1.93. LIMITATIONS: This study contains a small sample size from a single center and the conclusion of randomized controlled trials will be more convincing. CONCLUSIONS: Increasing temperature can effectively reduce the recurrence rate after RF, and the combination of atypical pain and higher NRS-11s could be a risk factor increasing the recurrence rate. The novel nomogram exhibited favorable survival stratification accuracy and shown a great potential for screening high-risk groups and evaluating the risk of recurrence rate.
