Enhanced Recovery After Surgery in Immediate DIEP Flap Breast Reconstruction: Reducing Length of Stay and Opioid Use

Background: To improve patient outcomes amid reduced healthcare resources during the COVID-19 pandemic, a single Canadian cancer center implemented an Enhanced Recovery After Surgery (ERAS) protocol for autologous DIEP flap breast reconstruction. Methods: This retrospective cohort study included 100 consecutive patients undergoing microsurgical breast reconstruction with DIEP flaps using the ERAS protocol and 100 patients using a standard protocol. Primary outcomes were the hospital length of stay and opioid use. Secondary outcomes included postoperative complications, laxative and antiemetic consumption. Results: In this study, 80% of the patients had immediate reconstruction, while the remaining patients received either delayed immediate or delayed reconstruction. Patients in the ERAS group had shorter hospital stays (2.8 vs 4.5 days; P < 0.001) and lower total opioid use (50.2 vs 136.3 mg; P < 0.001). This reduction was also observed when breaking down opiates per day of hospitalization (30.2 vs 18.2 mg; P < 0.001), and in the first 24 postoperatively hours (35.7 vs 67.6 mg; P < 0.001). The control group had a higher incidence of postoperative complications, including seroma, partial and total flap necrosis, compared to the ERAS group. However, readmission rates were similar between the two groups. Conclusion: Implementing the ERAS protocol for DIEP flap breast reconstruction can significantly reduce hospital length of stay and postoperative opioid requirements without increasing the risk of adverse events. This pattern holds true for immediate reconstructions with DIEP flaps.

Safety and efficacy of general anesthesia versus spinal anesthesia in percutaneous nephrolithotomy

Background: Percutaneous nephrolithotomy (PCNL) is the preferred treatment for the removal of large kidney stones, sized >20 mm. However, there is still an ongoing debate concerning the best anesthesia for PCNL. Aims and Objectives: The objective of this study was to assess and compare the efficacy and safety of spinal anesthesia (SA) versus general anesthesia (GA) in PCNL. Materials and Methods: A prospective randomized study included eighty-two patients who were enrolled to receive either SA or GA for PCNL. The study assessed patients’ characteristics, vital parameters, requirements for additional analgesia, and patient satisfaction. In addition, intraoperative and post-operative complications were documented. Patients’ satisfaction was also analyzed. Results: In both groups, the vital parameters were consistently maintained at safe levels during the procedures. Patients in the SA group exhibited a lower analgesia consumption on the 1st post-operative day compared to the GA group (P<0.05). Post-operative hypotension was higher in the SA group than in the GA group (17% vs. 7%). Patients in the GA group reported higher patient satisfaction scores than the SA group (mean 4.39+0.59 vs. 3.81+0.64). Conclusion: Both SA and GA are safe and effective in PCNL. SA is associated with fewer complications and reduced postoperative analgesia consumption. However, GA tends to offer higher satisfaction levels for patients. Each method of anesthesia has its own advantages and disadvantages. The final choice between general and SA should be based on the patient’s condition and surgical team preference.

Effect of Intermittent Thoracic Paravertebral Block on Postoperative Nausea and Vomiting Following Thoracoscopic Radical Resection of the Lung Cancer: A Prospective Randomized Trial.

To explore the benefits of ultrasound-guided intermittent thoracic paravertebral block (TPVB) combined with intravenous analgesia (PCIA) in alleviating postoperative nausea and vomiting (PONV) during video-assisted thoracic surgery (VATS). 120 patients with lung carcinoma undergoing VATS were included and divided into three groups: group S (single TPVB+PCIA), group I (intermittent TPVB+PCIA), and group P (PCIA). The patients' NRS scores, postoperative hydromorphone hydrochloride consumption, and intramuscular injection of bucinnazine hydrochloride were recorded. The incidence of PONV and complications were documented. Compared with the group P, both group I and group S had significantly lower static NRS scores from 1-48 hours after the operation (P <0.05), and the dynamic NRS score of group I at the 1-48 hours after the operation were significantly decreased (P <0.05). Compared with the group P, the proportion of patients with PONV in group I was significantly lower (P <0.05), while there was no significant difference in group S. Moreover, the hospitalization period of patients in group I was significantly reduced compared with the other two groups (P <0.01), and the patient satisfaction was significantly increased compared with the group P (P <0.05). Intermittent TPVB combined with PCIA can reduce the postoperative pain and the occurrence of PONV.

Comparative evaluation of continuous infusion versus programmed intermittent bolus techniques in erector spinae plane block in modified radical mastectomy - A preliminary randomised controlled trial.

Single-shot erector spinae plane block (ESPB) provides excellent analgesia in mastectomy in the immediate post-operative period but is not sufficient to maintain for prolonged duration. This study compares the efficacy of programmed intermittent bolus (PIB) versus continuous infusion (CI) techniques after ESPB by placing a catheter for mastectomy. After ethical approval and patient consent, ESPB was performed at the T4 level in 50 patients with an initial bolus of 20 mL 0.375% ropivacaine and a catheter placed 30 min before surgery. In the postoperative period, they were randomised to Group I - intermittent bolus of 20 mL 0.2% ropivacaine every 4 h for 24 h and Group C - continuous infusion of 0.2% ropivacaine at 5 mL/h for 24 h. The primary outcome was the 24-h fentanyl consumption by patient-controlled analgesia device. Data was analysed using Stata 14.0. Group I patients had reduced post-operative fentanyl consumption {mean [standard deviation (SD)]: 166 (139.17) µg vs 332 (247.96) µg, P = 0.002} and lower median NRS scores (1 h: 3 vs 5), (2 h: 3 vs 5), (4 h: 3 vs 5), (6 h: 4 vs 5) with a higher mean (SD) Quality of Recovery-15 score {134.4 (8.53) vs 127 (12.89), P = 0.020} compared to Group C, respectively. The 24-h dermatomal sensory coverage was more comprehensive in Group I compared to Group C. The PIB technique after ESPB provides decreased postoperative opioid consumption, better post-operative analgesia and quality of recovery compared to the CI technique in patients undergoing mastectomy.

Minimal important difference in postoperative morphine consumption after hip and knee arthroplasty using nausea, vomiting, sedation and dizziness as anchors.

Morphine-sparing effects are often used to evaluate non-opioid analgesic interventions. The exact effect that would warrant the implementation of these interventions in clinical practice (a minimally important difference) remains unclear. We aimed to determine this with anchor-based methods. This was a post hoc analysis of three studies investigating pain management after hip or knee arthroplasty (PANSAID [NCT02571361], DEX-2-TKA [NCT03506789] and Pain Map [NCT02340052]). The overall population was median aged 70, median ASA 2, 54% female. We examined the correlation between 0 and 24 h postoperative iv morphine equivalent consumption and the severity of nausea, vomiting, sedation and dizziness. The anchor was different severity degrees of these opioid-related adverse events. The primary outcome was the difference in morphine consumption between patients experiencing no versus only mild events. Secondary outcomes included the difference in morphine consumption between patients with mild versus moderate and moderate versus severe events. We used Hodges-Lehmann median differences, exact Wilcoxon-Mann-Whitney tests and quantile regression. The difference in iv morphine consumption was 6 mg (95% confidence interval: 4-8) between patients with no versus only mild events, 5 mg (2-8) between patients with mild versus moderate events and 0 mg (-4 to 4) between patients with moderate versus severe events. In populations comparable to this post-hoc analysis (orthopaedic surgery, median age 70 and ASA 2), we suggest a minimally important difference of 5 mg for 0-24 h postoperative iv morphine consumption.

Risk factors for prolonged length of stay after first single-level lumbar microdiscectomy

ObjectiveThe objective is to identify risk factors that potentially prolong the hospital stay in patients after undergoing first single-level open lumbar microdiscectomy.MethodsA retrospective single-centre study was conducted. Demographic data, medical records, intraoperative course, and imaging studies were analysed. The outcome measure was defined by the number of days stayed after the operation. A prolonged length of stay (LOS) stay was defined as a minimum of one additional day beyond the median hospital stay in our patient collective. Bivariate analysis and multiple stepwise regression were used to identify independent factors related to the prolonged hospital stay.ResultsTwo hundred consecutive patients who underwent first lumbar microdiscectomy between 2018 and 2022 at our clinic were included in this study. Statistical analysis of factors potentially prolonging postoperative hospital stay was done for a total of 24 factors, seven of them were significantly related to prolonged LOS in bivariate analysis. Sex (p = 0.002, median 5 vs. 4 days for females vs. males) and age (rs = 0.35, p ≤ 0.001, N = 200) were identified among the examined demographic factors. Regarding preoperative physical status, preoperative immobility reached statistical significance (p ≤ 0.001, median 5 vs. 4 days). Diabetes mellitus (p = 0.043, median 5 vs. 4 days), anticoagulation and/or antiplatelet agents (p = 0.045, median 5 vs. 4 days), and postoperative narcotic consumption (p ≤ 0.001, median 5 vs. 4 days) as comorbidities were associated with a prolonged hospital stay. Performance of nucleotomy (p = 0.023, median 5 vs. 4 days) was a significant intraoperative factor. After linear stepwise multivariable regression, only preoperative immobility (p ≤ 0.001) was identified as independent risk factors for prolonged length of postoperative hospital stay.ConclusionOur study identified preoperative immobility as a significant predictor of prolonged hospital stay, highlighting its value in preoperative assessments and as a tool to pinpoint at-risk patients. Prospective clinical trials with detailed assessment of mobility, including grading, need to be done to verify our results.

Epidural versus intravenous analgesia for pain control in kidney donors, a retrospective cohort study. Is there a kinship relationship?

Aims: Best care must be provided for live kidney donors, including postoperative pain control. Treatment options include iv intermittent analgesics, iv or epidural patient-controlled analgesia (PCA). In this study we aimed to compare these modalities with respect to their analgesic efficacy. Methods: A retrospective analysis of fifty-eight live donor nephrectomy patients operated in a 7-year-period in a university hospital performed. Investigational Review Board approval has been obtained. Data of the patients’ postoperative analgesia methods, degree of kinship with the recipient, postoperative pain scores, and rescue analgesic and antiemetic use were obtained. Correlation of postoperative pain scores with the analgesia technique was investigated, as well as with the degree of kinship of the donor and recipient. Results: Patient-controlled analgesia provided better postoperative pain control, with the epidural PCA being the best. Moderate to severe pain at 6th postoperative hour in the iv intermittent, iv PCA, and epidural PCA groups was 76, 37, and 14%, respectively. Rescue analgesic use on the day of operation was 32% and 5% in the iv intermittent and iv PCA groups respectively, with no rescue analgesic use in the epidural PCA group. Postoperative antiemetic consumption was also less with the epidural PCA (P=0.024 and P=0.027 for postoperative days 1 and 2, respectively). No correlation was detected between the pain and the degree of kinship. Conclusion: Epidural patient-controlled analgesia provides better postoperative pain control after live donor nephrectomy, compared with intravenous intermittent or patient-controlled analgesia. Postoperative pain scores were not related to the degree of kinship.

Improved Recovery after Vestibular Schwannoma Excision with Intratympanic Gentamicin Prehabilitation.

Translabyrinthine excision of a vestibular schwannoma is associated with acute vestibular failure. Preoperative intratympanic gentamicin (ITG) injections can improve objective balance function after surgery but its clinical benefits remain to be established. Adult patients undergoing translabyrinthine removal of a vestibular schwannoma between January 2014 and February 2018 underwent preoperative vestibular function testing. Patients were divided in to 3 groups, those with vestibular function (VF) who received ITG injections, those with VF but did not receive ITG and those with no VF. Groups were compared according to degree of vertigo, length of stay, time to unassisted mobilization, and postoperative anti-emetic consumption. Forty six patients had ITG injections (Group 1), 7 had residual VF but refused treatment (Group 2), 21 had no VF (Group 3). Group 1 had a significant improvement in vertigo over time whereas groups 2 and 3 did not. There was a statistically significant 70% decrease in time to independent mobilization between Group 1 and other groups and a 19% decrease in length of stay in Group 1 compared to other groups although this did not reach statistical significance. Two patients had injection-related complications. Group 1 used less anti-emetics than other groups but this was not statistically significant. Preoperative intratympanic gentamicin injection with vestibular rehabilitation exercises is associated with less postoperative vertigo and earlier postoperative mobilization. There was reduced duration of hospitalization and decreased consumption of anti-emetic but not significantly so possibly because of low numbers of patients in the no treatment group. 2 Laryngoscope, 134:3316-3322, 2024.

Efficacy of Oral Nefopam on Multimodal Analgesia in Total Knee Arthroplasty: A Prospective, Double-Blind, Placebo-Controlled, Randomized Trial

BackgroundMultimodal analgesia is central to pain management after total knee arthroplasty (TKA). This study aimed to evaluate the efficacy of adding oral nefopam to multimodal analgesia for post-TKA pain management. MethodsIn this prospective, double-blind, placebo-controlled, randomized trial, 100 patients who underwent TKA at our hospital were randomized to either the nefopam or the control group. After surgery, patients in the nefopam group received 200 mg of celecoxib, 150 mg of pregabalin, and 40 mg of nefopam twice daily to control postoperative pain. Patients in the control group received 200 mg of celecoxib, 150 mg of pregabalin, and a placebo. Oxycodone hydrochloride (10 mg) was used as the rescue analgesic. If the pain remained poorly controlled, 10 mg of morphine hydrochloride was injected subcutaneously as a secondary rescue analgesic. The primary outcome was the postoperative consumption of oxycodone and morphine as rescue analgesics. Secondary outcomes were postoperative pain assessed using the visual analogue scale (VAS), functional recovery assessed by the range of knee motion and ambulation distance, time until hospital discharge, indicators of liver function, and complication rates. ResultsPatients in the nefopam group had significantly lower postoperative oxycodone and morphine consumption within 24 hours after surgery and during hospitalization, lower VAS pain scores at rest and during motion within 24 h after surgery, better functional recovery on postoperative days 1 and 2, and a shorter hospital stay. However, the absolute reduction in 0 to 24 h opioid consumption, VAS pain scores, and knee range of motion did not exceed the reported minimal clinically important difference. Both groups had similar indicators of liver function and complication rates. ConclusionsAdding oral nefopam to multimodal analgesia resulted in statistically significant improvements in opioid consumption, VAS pain scores, and functional recovery. However, the amount of improvement may not be clinically important.

The Efficacy of Continuous Serratus Anterior and Erector Spinae Plane Blocks vs Intercostal Nerve Block in Uniportal-Vats Surgery: A Propensity-Matched Prospective Trial.

To evaluate the analgesic efficacy of continuous erector spinae plane block(c-ESPB) and serratus anterior plane block(c-SAPB) versus the intercostal nerve block (ICNB) in Uniportal-VATS in terms of pain control, drug consumption, and complications. Ninety-three consecutive patients, undergone one of the three peripheral nerve blocks after Uniportal-VATS, were prospectively enrolled. A 1:1 propensity score matching was used to minimize bias. C-ESPB and c-SAPB groups had no difference in morphine request upon awakening compared to ICNB. A higher VAS-score was recorded in c-ESPB compared to ICNB in the first 12 h after surgery. A significantly lower consumption of paracetamol in II postoperative day (p.o.d.) and tramadol in I and II p.o.d. was recorded in the c-ESPB group compared to the ICNB group. A higher dynamic VAS score was recorded at 24 h and 48 h in the ICNB group compared to the c-SAPB. No difference was found in safety, VAS-score and drug consumption between c-ESPB and c-SAPB at any given time, except for a higher tramadol request in c-SAPB in II p.o.d. C-ESPB and c-SAPB appear to have the same safety and analgesic efficacy when compared between them and to ICNB in Uniportal-VATS approach. C-ESPB showed a delayed onset of analgesic effect and a lower postoperative drug consumption compared to ICNB.

Efficacy of ultrasound-guided erector spinae plane block on analgesia and quality of recovery after minimally invasive direct coronary artery bypass surgery: protocol for a randomized controlled trial

BackgroundMinimally invasive direct coronary artery bypass (MIDCAB) surgery offers an effective option for coronary artery disease (CAD) patients with the avoidance of median sternotomy and fast postoperative recovery. However, MIDCAB is still associated with significant postoperative pain which may lead to delayed recovery. The erector spinae plane block (ESPB) is a superficial fascial plane block. There have not been randomized controlled trials evaluating the effects of ESPB on analgesia and patient recovery following MIDCAB surgery. We therefore designed a double-blind prospective randomized placebo-controlled trial, aiming to prove the hypothesis that ESPB reduces postoperative pain scores in patients undergoing MIDCAB surgery.MethodsThe study protocol has been reviewed and approved by the Ethical Review Committee of Peking University People’s Hospital. Sixty adult patients of either sex scheduled for MIDCAB surgery under general anesthesia (GA) will be included. Patients will be randomly allocated to receive either a preoperative single-shot ESPB with 30 mL of ropivacaine 0.5% (ESPB group) or normal saline 0.9% (control group). The primary outcomes are the difference between the two groups in numeric rating scale (NRS) scores at rest at different time points (6, 12, 18, 24, 48 h) after surgery. The secondary outcomes include NRS scores on deep inspiration within 48 h, postoperative hydromorphone consumption, and quality of patient recovery at 24 h and 48 h, using the Quality of Recovery-15 (QoR-15) scale. The other outcomes include intraoperative fentanyl requirements, the need for additional postoperative rescue analgesics, time to tracheal extubation and chest tube removal after surgery, incidence of postoperative nausea and vomiting (PONV) and postoperative cognitive dysfunction (POCD), intensive care unit (ICU) length of stay (LOS), hospital discharge time, and 30-day mortality. Adverse events will be also evaluated.DiscussionThis is a novel randomized controlled study evaluating a preoperative ultrasound-guided single-shot unilateral ESPB on analgesia and quality of patient recovery in MIDCAB surgery. The results of this study will characterize the degree of acute postoperative pain and clinical outcomes following MIDCAB. Our study may help optimizing analgesia regimen selection and improving patient comfort in this specific population.Trial registrationThe study was prospectively registered with the Chinese Clinical Trial Registry (trial identifier: ChiCTR2100052810).

Bilateral ultrasound-guided quadratus lumborum block versus bilateral transversus abdominis plane block for postoperative analgesia after cesarean section

Background For mothers caring for newborns, adequate pain control after cesarean section is critical, as is early ambulation to prevent thromboembolism and chronic abdominal and pelvic pain. Aim The primary goal of the research is to compare the effectiveness of ultrasound-guided quadratus lumborum block (QLB) versus transversus abdominis plane (TAP) block for postoperative analgesia and opioid consumption after a cesarean section. The secondary goal of the research is to assess the time required for each technique and postoperative complications and patient satisfaction in each group. Patients and methods Current research occurred in Elshatby University Hospital on 40 American Society of Anesthesiologists I or II studied cases with a gestation of at least 37 weeks (according to sample size calculation) scheduled for elective cesarean section. Results Comparing the time of analgesia between the two groups was longer in the QLB1 group than the control group (P≤0.001). The total amount of rescue analgesia (nalbuphine) consumption ranged between 0 and 6 mg with a mean value of 0.60±1.85 mg/24 h in the QLB1 group, and between 0 and 12 mg with a mean value of 8.40±5.30 mg/24 h in TAP block group. The total amount of postoperative nalbuphine consumption was greater in the TAP block group compared with the QLB1 group (P&lt;0.001). Patient satisfaction with pain control has been assessed on four-point scale like: excellent, good, fair and poor. Comparison between the two groups showed significantly better patient satisfaction in QLB1 group compared with the TAP block group where the P value was 0.016. Conclusion From the present research, the following can be concluded: ultrasound-guided QLB is a more influential method than TAP block for postoperative analgesia in studied cases undergoing cesarean section as it is more effective in reducing both somatic and visceral pain. Ultrasound-guided QLB is associated with a decrease in total opioid consumption, longer time of analgesia and greater studied case satisfaction.

Effect of 5% lidocaine-medicated plaster in preventing chronic postsurgical pain after knee replacement: protocol for a randomized double-blind placebo-controlled trial.

With an aging population, knee arthroplasty is increasingly common; however, chronic postsurgical pain (CPSP) affects up to 30% of patients. This study aims to evaluate the efficacy of 5% lidocaine-medicated plaster (LP5) in preventing CPSP among patients undergoing knee arthroplasty. This is a dual-center, randomized, double-blind, placebo-controlled trial involving 128 adult patients scheduled for knee arthroplasty. Participants will be randomly assigned, stratified by center, to either the LP5 group or the placebo group (n = 64 per group). The LP5 or placebo group will apply the patch 1day before surgery and on postoperative days 1-3, with multimodal analgesia administered postoperatively. Multimodal analgesia will include intraoperative flurbiprofen axetil and postoperative patient-controlled sufentanil. The primary outcome is the pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at 3 months postoperatively. Secondary outcomes will include WOMAC stiffness, function, and total scales; Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale; 36-Item Short Form Health Survey (SF-36); postoperative pain scores; Visual Analog Scale (VAS) sleep scores; postoperative sufentanil consumption; need for rescue analgesia; length of Post-Anesthesia Care Unit (PACU) stay; length of hospital stay; and 90-day mortality. Safety outcomes will include assessments of hypotension, hypertension, bradycardia, tachycardia, arrhythmia, interventions for haemodynamic events, headache, dizziness, nausea, vomiting, local skin allergy, wound infection, and toxic reaction. Data will be analyzed following a modified intention-to-treat approach. This study aims to provide high-quality evidence for the efficacy and safety of LP5 in preventing CPSP in patients undergoing knee arthroplasty.

Analgesic and hemodynamic effects of intravenous magnesium sulfate infusion versus lidocaine infusion in patients undergoing thyroid surgery for toxic goiter resection: a randomized controlled study

Background Anesthesia for toxic goiter resection is challenging as manipulation of the thyroid gland and inadequate postoperative pain control could lead to hemodynamic instability due to stress and a neurohormonal response. Both magnesium sulfate and lidocaine are known for their analgesic effects and decreasing stress response. Herein, we compared the previous two medications regarding intraoperative hemodynamics and postoperative analgesia. Patients and methods 57 patients who underwent toxic goiter resection were enrolled in this prospective randomized trial (group M received magnesium sulfate, group L received lidocaine, and group C received normal saline). Intraoperative hemodynamics and postoperative analgesic profiles were assessed. Results Both injection groups expressed significantly lower pain scores compared with control group at Post anaesthesia care unit (PACU) and one-hour postoperative. Postoperative fentanyl consumption was significantly lower, and the time to first analgesic request was significantly prolonged in Magnesium and Lidocaine groups than in the control group. The previous beneficial effects were more prominent in the Magnesium Group compared with the Lidocaine Group. There was no significant difference in mean arterial pressure (MAP) and heart rate (HR) among the three study groups at the baseline, after the end of infusion, and after induction. Nonetheless, there was a significant rise in mean arterial pressure and heart rate values in the control group compared with the Magnesium and Lidocaine Groups with intubation and during the first hour of surgery. Conclusion Both magnesium sulfate and lidocaine have beneficial hemodynamic stabilizing and analgesic effects in patients undergoing thyroid surgery for toxic goiter, with a slight superiority for magnesium.

The Effect of Preoperative Gabapentin on the Duration of Spinal Anaesthesia in Patients Undergoing Lower Limb Surgery: A Randomized Controlled Clinical Trial

Background: In the present study, we aim to examine oral gabapentin efficacy as an adjuvant to spinal anesthesia. Methods: This prospective, clinical, randomized trial included subjects between 20 and 60 years undergoing lower limb surgeries categorized into two cohorts. Group (G) received gabapentin (900 mg) in two divided doses prior to spinal anesthesia; (300 mg 10 hrs prior to spinal anesthesia induction as well as 600 mg 2 hrs before spinal anesthesia). In contrast, the control Group (C) received only spinal anesthesia. The onset, as well as the duration of spinal anesthesia, were the primary outcome, while the secondary outcome was the postoperative nalbuphine consumed. Results: A total of 60 cases were evenly categorized into two cohorts. Both groups demonstrated no differences regarding motor and sensory block onset and duration. The group receiving preoperative gabapentin had a significant decrease in postoperative nalbuphine consumption with a mean of 20.8±9.4 mg compared to the control group, which showed an increased consumption of 28.9±10.4 mg with a p-value of 0.006. Further analysis of the Visual Analog Score (VAS) in both groups revealed that the decrease in total nalbuphine consumption was found at (8 and 10 hrs) postoperatively, with p values of 0.016 and 0009, respectively. Conclusion: Gabapentin administration (900 mg) within 10 hrs of surgery in two subdivided doses prior to spinal anesthesia had no effect on onset and duration of spinal anesthesia but had a delayed beneficial postoperative analgesic effect. Clinical Trial Registration Number: This trial was registered at ClinicalTrials.gov (NCT05659810, URL: https://clinicaltrials.gov/ct2/show/NCT05659810in 21st December 2022.

Comparison of Erector Spinae Plane Block and Pectointercostal Facial Plane Block for Enhanced Recovery After Sternotomy in Adult Cardiac Surgery

This study aimed to investigate and compare the effects of the pectointercostal fascial plane block (PIFPB) and the erector spinae plane block (ESPB) on enhancing the recovery of patients who undergo cardiac surgery. A randomized, controlled, double-blinded study. The operating rooms and intensive care units of university hospitals. One hundred patients who were American Society of Anesthesiologists class II to III aged 18-to-70 years scheduled for elective cardiac surgery. Patients were randomly assigned to undergo either ultrasound-guided bilateral PIFPB or ESPB. Patients shared comparable baseline characteristics. Time to extubation, the primary outcome, did not demonstrate a statistically significant difference between the groups, with median (95% confidence interval) values of 115 (90-120) minutes and 110 (100-120) minutes, respectively (p = 0.875). The ESPB group had a statistically significant reduced pain score postoperatively. The median (IQR) values of postoperative fentanyl consumption were statistically significantly lower in the ESPB group than in the PIFPB group (p < 0.001): 4 (4-5) versus 9 (9-11) µg/kg, respectively. In the ESPB group, the first analgesia request was given 4 hours later than in the PIFPB group (p < 0.001). Additionally, 12 (24%) patients in the PIFPB group reported nonsternal wound chest pain, compared with none in the ESPB group. The median intensive care unit length of stay for both groups was 3 days (p = 0.428). Erector spinae plane block and PIFPB were found to equally affect recovery after cardiac surgery, with comparable extubation times and intensive care unit length of stay.

'We're outside the norm again because of the thing that allowed us to be inside the norm': An interpretative phenomenological analysis of the experience of developing an alcohol use disorder after bariatric surgery.

Studies indicate that bariatric surgery is associated with an increased risk of alcohol use disorder (AUD). It is considered some patients develop the disorder after surgery, without having antecedents of preoperative alcohol problems. This qualitative study aimed to explore the experiences of people who developed AUD postoperatively and understand how they make sense of the onset of this disorder. A semi-directed interview was carried out with eight adults who had undergone bariatric surgery and developed AUD de novo postoperatively. Data were analysed using interpretative phenomenological analysis. Four superordinate themes emerged: (1) 'losing control over drinking and self after surgery'; (2) 'feelings of guilt, shame and loss contrasted with perceptions of still being lucky'; (3) 'trying to make sense of the onset of AUD'; and (4) 'retrospective evaluation of bariatric surgery and preoperative information'. These themes indicated loss of control was a central aspect of participant's experiences of postoperative alcohol consumption. AUD was associated with negative emotions and cognitions, but several participants still considered themselves lucky. All tried to make sense of this disorder's onset; many felt they would not have developed AUD if they had not undergone surgery. The onset of AUD influenced their current perceptions and feelings about surgery and the preoperative information regarding AUD risks. Taken together, these results provide insight into the subjective experience of suffering from new-onset AUD post-surgery. However, more studies are necessary to gain a better understanding of the physical and psychological implications of postoperative AUD.

The effect of tourniquet use on postoperative opioid consumption after ankle fracture surgery- a retrospective cohort study.

A pneumatic tourniquet is often used during ankle fracture surgery to reduce bleeding and enhance the visibility of the surgical field. Tourniquet use causes both mechanical and ischemic pain. The main purpose of this study was to evaluate the effect of tourniquet time on postoperative opioid consumption after ankle fracture surgery. We retrospectively reviewed the files of 586 adult patients with surgically treated ankle fractures during the years 2014-2016. We evaluated post hoc the effect of tourniquet time on postoperative opioid consumption during the first 24 h after surgery. The patients were divided into quartiles by the tourniquet time (4-43 min; 44-58 min; 59-82 min; and≥83 min). Multivariable linear regression analysis was used to evaluate the results. Tourniquets were used in 486 patients. The use of a tourniquet was associated with an increase in the total postoperative opioid consumption by 5.1 mg (95 % CI 1.6-8.5; p=0.004) during the first 24 postoperative hours. The tourniquet time over 83 min was associated with an increase in the mean postoperative oxycodone consumption by 5.4 mg (95 % CI 1.2 to 9.7; p=0.012) compared to patients with tourniquet time of 4-43 min. The use of a tourniquet and prolonged tourniquet time were associated with higher postoperative opioid consumption during the 24h postoperative follow-up after surgical ankle fracture fixation. The need for ethical approval and informed consent was waived by the Institutional Review Board of Northern Ostrobothnia Health District because of the retrospective nature of the study.

Ultrasound guided erector spinae plane block versus intrathecal morphine for analgesia following major hepatopancreaticobiliary surgery

ABSTRACT Background Intrathecal morphine (ITM) has been evidenced to provide efficient analgesia for hepatopancreaticobiliary surgery (HPB) in the postoperative period. Despite its benefits, ITM carries certain risks, such as pruritus, postoperative nausea and vomiting, and of utmost importance, the possibility of delayed respiratory depression. We conducted this study to compare the effectiveness of bilateral erector spinae plane block (ESPB) and ITM for analgesia following major HPB surgery. Our hypothesis was that bilateral ESPB would lead to a significant reduction in opioid consumption within the first 24 hours following surgery, with a lower incidence of side effects. Methods Forty patients with scheduled major HPB surgery were randomly allocated to receive either bilateral ESPB (n = 20) or ITM (n = 20) before general anesthesia induction. The primary outcome was cumulative postoperative nalbuphine consumption in the first 24 hours. Results Cumulative nalbuphine consumption at 24 hours after surgery was significantly lower in the ITM group compared to ESPB (3.05 ± 0.38 versus 6.56 ± 0.88 respectively). However, the ESPB group demonstrated effective pain control as indicated by pain scores of ≤2 at rest and ≤3 when coughing throughout all measured time points. Moreover, ESPB significantly reduced the incidence of postoperative nausea, vomiting (p = 0.03), and pruritus (p = 0.003) within the first 24 hours postoperatively compared to ITM. Conclusions Although bilateral ESPB resulted in higher opioid consumption than ITM in the first 24 hours after major HPB surgery, the adverse effects were less with minimal or no risk of hemodynamic instability.
