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.

The Analgesic Efficacy of Erector Spinae Plane Block in Ankle and Foot Surgery: A Randomized Controlled Study

Background: During ankle and foot surgeries, we often use different regional analgesic modalities to reduce patient pain during and after orthopaedic and surgical operations. The purpose of this research was to examine the effectiveness of erector spinae plane (ESP) block for postoperative pain management after ankle and foot surgeries. Methods: Sixty patients, aged 18 to 65, with ASA physical status I, participated in a randomized controlled clinical experiment. Patients were divided into two groups (E and C) at random, with group (E) receiving ESP block and group (C) receiving a placebo. The patients' medical histories were evaluated, and they were all examined and tested. Results: Observations At 2, 4, 12 & 24 hours postoperatively, the ESP group had substantially lower visual analogue scale (VAS) ratings in contrast to the control group. The total quantity of fentanyl and pethidine given during, and after surgeries were both considerably lower in the Erector group in comparison with the control group. Total nonsteroidal anti-inflammatory medication usage did not vary significantly among the 2 groups, however. Conclusions: ESP is safe & effective technique in decreasing pain and providing adequate analgesic effect in ankle and foot ssurgeries. Trial Registration: This study was prospectively registered on https://clinicaltrials.gov/ under the NCT05708742 number (principal investigator: Mohamed Ahmed Hamed), registration date: 24/01/ 2023.

Retrospective case-control non-inferiority analysis of ultrasound-guided erector spinae plane block in dogs undergoing mini-hemilaminectomy for intervertebral disc disease.

Veterinary medicine has seen significant advancements in locoregional anaesthesia and pain management, including the emergence of the erector spinae plane (ESP) block. However, limited clinical evidence exists on its efficacy and safety. This study compares ultrasound-guided ESP block (ESP group) with an intraoperative intravenous ketamine infusion analgesic protocol (CRI group) in dogs undergoing thoracolumbar mini-hemilaminectomy, focusing on intraoperative opioid consumption, cardiovascular response to surgical stimulation (CR), postoperative pain scores (PS), and postoperative opioid consumption. Retrospective, case-control, non-inferiority study conducted in a single centre. Data collected included demographics, bupivacaine dose, ESP block operator, intraoperative recorded variables (haemodynamic variables, CR, complications, rescue analgesia), pre- and postoperative analgesia, 24-hour PS and opioid administration, first food intake post-extubation and postoperative complications. Univariate and multiple regression analyses were applied. One-hundred dogs were included, 75 in the ESP group and 25 in the CRI group. Univariate analysis revealed no significant differences between treatment groups in terms of CR, PS, postoperative rescue analgesia, intraoperative and postoperative opioid consumption, or time to first meal intake. However, the multivariate regression analysis indicated that dogs receiving ketamine infusion had higher CR suspected to be nociception-related (p = 0.036), and higher postoperative opioid consumption (p = 0.013). Our study suggests that ultrasound-guided ESP block is as effective as intraoperative ketamine infusion providing perioperative analgesia in dogs undergoing thoracolumbar mini-hemilaminectomy for intervertebral disc disease. ESP group showed significantly lower CR suspected to be nociception-related intraoperatively and lower postoperative opioid consumption within the initial 24 hours.

The impact of erector spinae plane (ESP) block on neurophysiological monitoring in patients undergoing scoliosis repair

ABSTRACT Background Preventive analgesia is designed to ensure perioperative pain control. The erector spinae plane (ESP) block may abolish the neuroendocrine stress response and augments controlled hypotensive anesthesia. But to what extent does it interfere with spinal cord function. Methods The patient’s population is divided into Group N (control) and Group E (ESP Group). A baseline for the amplitude and/or latency of either somatosensory evoked potentials (SSEPs) or motor evoked potentials (MEPs) were collected (30 min after induction of anesthesia and after full reverse of muscle relaxant before performing ESP block) in group E, the change from the baseline was recorded as a percent decrease. The total dose of anesthetics, the adjuvant analgesics and the postoperative complications were recorded. Results The change in the latency and the amplitude of SSEPs and MEPs among the two groups showed a non-significant change from the baseline. The intra-operative fentanyl consumption was significantly lower in group E than in C. The mean was 21.5 ± 25 vs 178.2 ± 46 mg respectively. The total doses of propofol and dexmedetomidine were lower in group E than in C. 18% of the patients in group E requested a rescue analgesic at a median of 70 (65) min postoperatively vs 55% of those in group C that requested analgesics earlier at a median 16(6) min. Conclusion The ESP block can be safely used without interfering with the monitoring of the somatosensory and MEPs during complex spinal surgery.

Efficacy of bilateral erector spinae block for intraoperative and post-operative analgesia in lumbar decompression surgeries: A prospective randomized controlled trial

Background: Lumbar surgery is known to cause severe pain in the post-operative period. Modalities to reduce pain in the perioperative period include opioids, non-steroidal anti-inflammatory drugs, neuraxial blocks, and erector spinae block (ESB). Aims and Objectives: In this study, we aimed to evaluate whether ESB could reduce perioperative pain, opioid consumption, and muscle relaxant consumption. Materials and Methods: Fifty patients scheduled for lumbar decompression spine surgery were randomly allocated to two groups, the erector spinae plane (ESP) group (n=25) and the control group multimodal analgesia group (n=25). Intraoperative hemodynamics, muscle relaxant requirement, opioid consumption post-operative visual analog score, and rescue analgesia were evaluated. Results: Compared with the control group, heart rate (91.24±14.86 and 90.20±14.26) (77.12±11.96 and 77.44±11.96) arterial blood pressures (87.12±8.45 mmHg) (85.25±7.25) (78.73±5.56 and 79.64±5.95) were higher during surgical incision and 1st-time interval than in ESP group, respectively. The visual analog scale scores were higher in the control group than in the ESP group during all measurements of time. The requirement for rescue analgesia was more in the control group compared to the ESP group. Post-operative analgesia lasted for 15–18 h. Conclusion: Ultrasound-guided ESP block is a simple and safe technique which provides effective intraoperative, and post-operative analgesia and patient satisfaction with reduced opioid and muscle relaxant consumption.

Comparison of midpoint transverse process to pleura (MTP) block and erector spinae plane block (ESP) for postoperative analgesia in modified radical mastectomy patients: A double-blinded, randomized control trial.

Modified radical mastectomy (MRM) is associated with moderate severity of postoperative pain. Besides intravenous (IV) analgesics, various nerve blocks are being described for pain relief of MRM patients. We compared erector spinae plane (ESP) block with midpoint transverse process to pleura (MTP) block in these patients for postoperative analgesia. After receiving ethical committee approval from the institutional ethics committee (AIIMS, Jodhpur) and written informed consent from study participants, 66 patients who were assigned American Society of Anesthesiologists (ASA) physical status I and II, aged 18-75 years, and were scheduled to undergo MRM were enrolled and randomly allocated into two groups. Unilateral block was given before surgery at T3 or T4 level and with 15 ml of 0.5% ropivacaine in both the groups. Infusion of 0.5% ropivacaine (Neon laboratories limited, Mumbai, India) and 0.2% ropivacaine at a rate of 5 ml/h was maintained intraoperatively and postoperatively, respectively. Pain was assessed using the Visual Analogue Scale (VAS) for the next 24 hours. The total number of patients needing rescue analgesia, the total amount of rescue analgesics consumed in the next 24 hours, and patient satisfaction score were also compared between groups. Demographics and baseline vitals were comparable in the groups. On comparing VAS scores in both the groups during rest and movement at different time intervals, there was no difference in pain scores during the initial two hours. From the third hour, there was a statistically significant difference (P < 0.001) in pain VAS scores in both groups. The ESP group had lower VAS scores compared to the MTP group when followed for the next 24 hours. There was a statistically significant difference in patient satisfaction. ESP block is more efficacious when compared to MTP block for postoperative analgesia in MRM patients.

Erector spinae plane block reduces opioid consumption and improves incentive spirometry volume after cardiac surgery: A retrospective cohort study.

Effective postoperative pain management is vital in cardiac surgery to prevent opioid dependency and respiratory complications. Previous studies on the erector spinae plane (ESP) block have focused on single-shot applications or immediate postoperative outcomes. This study evaluates the efficacy of continuous ESP block vs conventional care in reducing opioid consumption and enhancing respiratory function recovery postcardiac surgery over 72 hours. A retrospective study at a tertiary hospital (January 2021-July 2022) included 262 elective cardiac surgery patients. Fifty-three received a preoperative ESP block, matched 1:1 with a control group (n = 53). The ESP group received 0.5% ropivacaine intraoperatively and 0.16% ropivacaine every 4 hours postoperatively. Outcomes measured were cumulative oral morphine equivalent (OME) dose within 72 hours postextubation, daily maximum numerical rating scale (NRS) ≥3, incentive spirometry volume, and %baseline performance, stratified by surgery type (sternotomy or thoracotomy). Significant OME reduction was observed in the ESP group (sternotomy: median decrease of 113 mg, 95% CI: 60-157.5 mg, p < 0.001; thoracotomy: 172.5 mg, 95% CI: 45-285 mg, p = 0.010). The ESP group also had a lower risk of daily maximum NRS ≥3 (adjusted OR sternotomy: 0.22, p < 0.001; thoracotomy: 0.07, p < 0.001), a higher incentive spirometry volumes (sternotomy: mean increase of 149 mL, p = 0.019; thoracotomy: 521 mL, p = 0.017), and enhanced spirometry %baseline (sternotomy: mean increase of 11.5%, p = 0.014; thoracotomy: 26.5%, p < 0.001). Continuous ESP block was associated with a reduction of postoperative opioid requirements, lower instances of pain scores ≥3, and improve incentive spirometry performance following cardiac surgery. These benefits appear particularly prominent in thoracotomy patients. Further prospective studies with larger sample size are required to validate these findings.

Efficacy of Bilateral Erector Spinae Block in Patients Undergoing Posterior Spine Fusion Surgeries: A Comparative Randomised Controlled Trial.

Introduction During spine surgeries, various levels of tissue injury can result in varying hemodynamic responses and significant postoperative pain. Perioperative pain management is essential to controlling hemodynamic responses and postoperative pain management. Erector spinae plane (ESP) blocks can help alleviate this pain by blocking the dorsal rami of the spinal nerve. This study aims to evaluate the efficacy of ESP by assessing the perioperative opioid requirement, hemodynamic parameters, and visual analogue score (VAS) during the postoperative period. Methods In this study, 56 patients underwent elective posterior spine fusion surgeries under conventional anaesthesia and were allocated into two groups: 28 patients were included in the conventional group (Group C) and 28 patients in the ESP group (Group E). Group C patients received 20 ml of 0.9% sodium chloride (NaCl) on each side, and Group E patients received 20 ml of 0.25% bupivacaine + 4 mg dexamethasone on each side under ultrasound sonography guidance. Postoperative pain was assessed using the VAS score. The hemodynamic parameters during the intraoperative period, the time for the first opioid analgesia requirement until 24 hours in the postoperative period, and the amount of cumulative opioid consumption during the perioperative period were observed. Results Postoperative VAS was lower in Group E (P < 0.001). There were significant differences in hemodynamic parameters: heart rate (P < 0.045), systolic blood pressure (P < 0.002), diastolic blood pressure (P < 0.003), and mean arterial pressure (P < 0.002) at the time of incision in Group E. Intraoperative opioid requirements at the time of incision (P < 0.036), 60th minutes (P < 0.023), 120th minutes (P < 0.023), and postoperative opioid requirements at the first hour (P < 0.001), sixth hour (P < 0.004), 14th hour (P < 0.025), 20th hour (P < 0.009), and 24th hour (P < 0.025) had lower opioid requirements in Group E than Group C. Conclusion ESP block is a more site-specific dorsal rami block with a better perioperative hemodynamic profile, a part of multimodal analgesia intraoperatively, and excellent postoperative analgesia with fewer postoperative opioid requirements in multilevel spine fusion surgeries.

Ultrasound-guided erector spinae plane block versus port site infiltration for postoperative pain and quality of recovery in adult patients undergoing laparoscopic cholecystectomy: An assessor-blinded randomised controlled trial.

Pain following laparoscopic cholecystectomy (LC) is common and results in poor quality of recovery. Our study aimed to compare the analgesic efficacy of port site local infiltration, novel erector spinae plane (ESP) block, and standard regimen in patients undergoing LC and its impact on functional recovery. After ethical approval and registering the trial, we randomly allocated 105 adult patients undergoing LC to three groups: Group I (n = 35), received multimodal analgesia; Group II (n = 35), received pre-incisional port site infiltration with 20 ml of 0.375% bupivacaine; and Group III (n = 35), preoperative bilateral ESP block with 20 ml of 0.375% bupivacaine bilaterally was administered. Pain severity, fentanyl consumption, and time to first rescue analgesia were recorded over 24 h. Quality of recovery (QoR-15) was assessed at baseline and 24 h postoperatively. Pain in the first 6 h was lowest in the ESP group (P < 0.001). Although static pain in the infiltration group was comparable with that in the ESP group after 6 h (P > 0.05), dynamic pain was better in the ESP group till 20 h postoperatively (P < 0.05). Fentanyl consumption was significantly lower in the ESP group (P < 0.001). Global and sub-dimensional QoR-15 scores were significantly higher only in the ESP group at 24 h compared to the other two groups (P < 0.001). The infiltration group did better than the control group in terms of total opioid requirement (P < 0.001) and Visual Analogue Scale (VAS) score after 6 h (P < 0.001). ESP block provided lower postoperative pain scores with opioid-sparing and better quality of recovery in patients undergoing LC.

Lomber mikrodiskektomi ameliyatı geçiren hastalarda alt torasik erektör spina bloğunun postoperatif ağrı yönetimine etkisi

Purpose: Lumbar disk hernia is very common reason for spinal surgery and usually treats with surgical interventions. The primary aim of this randomized controlled study was to determine the effect of low thoracic ultrasound guided erector spinae plane (ESP) block on postoperative pain management in lumbar microdiscectomy surgery.&#x0D; Materials and Methods: Totally 42 adults scheduled for elective lumbar microdiscectomy surgery and assigned into two groups as Group ESP and Group Control. Anesthesia was induced with propofol 2mg/kg, rocuronium 0.6 mg/kg, fentanil 2µg/kg and maintained with total intravenous anesthesia (propofol 4-8 mg/kg/h and remifentanil 0.03-0.05 µg/kg/min), N2O/O2 mixture %60/40 for all patients. When patients were positioned at prone, ESP or sham block performed bilaterally. ESP performed with bupivacain 0.5% 15 mL+lidocain 2% 5 mL in ESP group and saline 20 mL for sham group at the T10 level of spine. The postoperative analgesia provided with morphine 0.1 mg/kg intravenously and diclofenac Na 75 mg intramuscularly at last 30 minutes of surgery for all patients. Postoperative visual analog scale (VAS) scores, meperidine requirements and patients’ satisfaction were recorded. &#x0D; Results: There were significant differences between Group ESP and Group Control in meperidine requirement, VAS scores at rest and leg movement and patients’ satisfaction. Time to first analgesic need was median 62.5 min (interquartile range 5-180) in Group ESP and median 7.50 min (interquartile range 5-10) in Group Control.&#x0D; Conclusion: ESP can significantly reduce postoperative pain scores (VAS at rest and leg movement), meperidine requirement and can provide better patients’ satisfaction, postoperatively.

Ultrasound-guided erector spinae plane block compared to serratus anterior muscle block for postoperative analgesia in modified radical mastectomy surgeries: A randomized control trial.

The present study was undertaken to compare the analgesic efficacy of erector spinae plane (ESP) block with serratus anterior muscle (SAM) block in patients undergoing modified radical mastectomy (MRM). We hypothesized that ESP block would provide better postoperative pain relief than SAM block following MRM. Eighty American Society of Anaesthesiologists (ASA) I-II adult females, scheduled for MRM, were randomly allocated to receive either ultrasound-guided ipsilateral single-shot ESP or SAM block after induction in the respective planes, using 20 ml of 0.25% ropivacaine. Both the groups received postoperative intravenous patient-controlled analgesia (IV-PCA) (morphine) for 24 h. The primary outcome was to assess pain severity using a visual analogue scale (VAS) score. Postoperative 24-h opioid consumption, time to first opioid analgesia, hemodynamic variables, total dose of antiemetics, and safety profile of both the blocks were also evaluated. Data analysis was carried out using Statistical Package for the Social Sciences version 21.0 (SPSS Inc. Chicago, Illinois, USA). VAS scores were lower in the ESP block group, at rest and on movement, and the difference was statistically significant (p < 0.05). Postoperative morphine consumption was also significantly less in patients receiving ESP block as compared to SAM block (3.13 ± 1.44 mg vs 4.33 ± 1.69 mg; P = 0.001). The time to first analgesia request was significantly prolonged in the ESP group as compared to the SAM group (9.58 ± 4.11 h vs 6.46 ± 2.95 h; P = 0.001). No major side effects were observed in any of the study groups. ESP block provides better analgesia as compared to SAM block after MRM. CTRI/2019/03/018067.

Pre-operative erector spinae plane block should be considered a viable option for laparoscopic colectomies.

The Erector Spinae Plane (ESP) block is a recent development in the field of regional anaesthesia and has been increasingly explored for abdominal surgeries to reduce opioid use and improve pain control. Colorectal cancer is the commonest cancer in multi-ethnic Singapore and requires surgery for curative treatment. ESP is a promising alternative in colorectal surgeries, but few studies have evaluated its efficacy in such surgeries. Therefore, this study aims to evaluate the use of ESP blocks in laparoscopic colorectal surgeries to establish its safety and efficacy in this field. A prospective two-armed interventional cohort study comparing T8-T10 ESP blocks with conventional multimodal intravenous analgesia for laparoscopic colectomies was conducted in a single institution in Singapore. The decision for doing an ESP block versus conventional multimodal intravenous analgesia was made by a consensus between the attending surgeon and anesthesiologist. Outcomes measured were total intra-operative opioid consumption, post-operative pain control and patient outcome. Post-operative pain control was measured by pain score, analgesia use, and amount of opioids consumed. Patient outcome was determined by presence of ileus. A total of 146 patients were included, of which 30 patients received an ESP block. Overall, the ESP group had a significantly lower median opioid usage both intra-operatively and post-operatively (p = 0.031). Fewer patients required patient-controlled analgesia and rescue analgesia post-operatively for pain control (p < 0.001) amongst the ESP group. Pain scores were similar and post-operative ileus was absent in both groups. Multivariate analysis found that the ESP block had an independent effect on reducing intra-opioid consumption (p = 0.014). Multivariate analysis of post-operative opioid use and pain scores did not yield statistically significant results. The ESP block was an effective alternative regional anaesthesia for colorectal surgery that reduced intra-operative and post-operative opioid use while attaining satisfactory pain control.

Robot-assisted radical prostatectomy: comparison of subarachnoid analgesia, erector spine plane block, and intravenous analgesia for postoperative pain management.

Laparoscopic and robotic prostatectomy allows a higher precision and a magnified view of the surgical field but it did not show to be characterized by a lower pain compared to open surgery so the management of postoperative pain still remains an important issue. We enrolled 60 patients randomized in 1:1:1 ratio into three groups: group SUB: treated with a lumbar subarachnoid injection of 10.5 mg ropivacaine, 30 μg clonidine, 2 μg/kg morphine, and 0.03 μg/kg sufentanil; groups ESP: treated with a bilateral erector spinae plane (ESP) block with 30 μg clonidine, 4 mg dexamethasone, 100 mg ropivacaine; group IV: treated with 10 mg morphine intramuscular 30 minutes before the end of the surgery and a postoperative iv continuous infusion of 0.625 mg/hr morphine in the first 48 hours after the intervention. Numeric rating scale score in the first 12 hours after intervention was significantly lower in SUB group compared to both IV group and ESP group with a maximum difference at 3 hours after intervention (0.14±0.35 vs 2.05±1.10, P <0.001 and 0.14±0.35 vs 1.15±0.93, P <0.001, respectively). Intraoperative supplemental doses of sufentanil were not required by SUB group, whereas IV and ESP groups required an additional dose of 24±10.7 μg and 7.5±5.5 μg, respectively (P <0.001). Subarachnoid analgesia is an effective strategy to manage postoperative pain in robot-assisted radical prostatectomy; it allows to reduce both intraoperative and postoperative opioid consumption and the amount of inhalation anesthetics compared to intravenous analgesia. ESP block might be an effective alternative in patients with contraindications to subarachnoid analgesia.

Regional Analgesia for Laparoscopic Cholecystectomy Using Ultrasound-guided Quadratus Lumborum Block or Erector Spinae Block: A Randomized Controlled Trial

BACKGROUND: Postoperative pain increases the incidence of venous thrombosis and respiratory complications, prevents early postoperative ambulation, and prolongs hospital stay. Fascial plane injections such as erector spinae plane (ESP) block and quadratus lumborum (QL) blocks are popular methods for postoperative pain control and reducing opioid consumption. OBJECTIVES: We aimed to evaluate the analgesic effects of ultrasound-guided ESP versus QL block during laparoscopic cholecystectomy for the reduction of pain and analgesic consumption. STUDY DESIGN: Prospective, double-blind, single-center, randomized controlled clinical trial. SETTING: Minia University Hospital, Minia Governorate, Egypt. METHODS: Patients scheduled for laparoscopic cholecystectomy from April 2019 through December 2019 were randomly allocated into 3 groups. After induction of general anesthesia, Group A received an ESP block, group B received a QL block, and group C didn’t receive any block (control). The main outcome was the time to the first analgesic request. Secondary outcomes were the pain intensity measured by the Visual Analog Scale at one, 2, 4, 6, 8, 12, 16, 20, and 24 hours postoperatively at rest and cough. The total analgesic requirement during the first 24 postoperative hours, hemodynamics, and any complications were recorded. RESULTS: Sixty patients scheduled for elective laparoscopic cholecystectomy were enrolled; the clinical and demographic data were similar in the 3 groups. Groups A and B had lower VAS scores at cough than Group C in the first postoperative 2 hours. Compared to Group C, a higher score was reported at 8, 12, and 16 hours in Group A, and at 8 and 16 hours in Group B. Group B had a higher score at 4 hours than Group A. At rest, Group C showed higher scores than Groups A and B in the first 2 hours, while higher scores were noted at 16 hours in Group A and 12 hours in Group B. Time to first request of analgesia was significantly prolonged in Group A than in Groups B and C (P &lt; 0.001). Our study showed that Groups A and B had lower postoperative analgesic requirements than Group C (P &lt; 0.05). LIMITATIONS: This study had a small number of patients enrolled. CONCLUSIONS: Both ESP and QL blocks effectively reduced VAS scores at both cough and rest. There was a decreased total consumption of analgesics in the first postoperative 24 hours with a longer duration of analgesia, which lasted 16 hours in the ESP group and 12 hours in the QL group.

Efficacy of ultrasound-guided erector spinae plane block &lt;i&gt;versus&lt;/i&gt; transversus abdominis plane block for intraoperative and postoperative pain control in total laparoscopic hysterectomy: results of the ARTEMIDE randomised controlled trial

Laparoscopic hysterectomy (LH), one of the most common surgeries among women, results in moderate-to-severe postoperative pain. The use of the transversus abdominis plane (TAP) block for pain management in LH has been evaluated but with conflicting results. The erector spinae plane (ESP) block has emerged as an effective and safe technique for relieving visceral pain. This study aimed to compare the analgesic efficacy of posterior TAP block versus ESP block following LH. We conducted a prospective, randomised, multicentre study. Seventy-six patients (American Society of Anesthesiologists I–III) scheduled for elective LH were included in the final analysis. The interventions performed were posterior TAP block (TAP group) and ESP block at T8 (ESP group). We adopted numerical rating scale (NRS) scores for pain at different time points, intraoperative remifentanil need, rescue analgesic requirements, incidence of postoperative nausea and vomiting in the first 36 postoperative hours, and days of hospitalisation as criteria of evaluetion. At nearly all time points, NRS scores did not significantly differ between the TAP and ESP groups. The TAP group had higher NRS scores for pain in the immediate postoperative period (p=0.008). The need for intraoperative remifentanil was higher in the TAP group (p=0.0018). When needed, remifentanil was infused at slower maximum infusion rates in the ESP group than in the TAP group (mean±SD: 0.02±0.04 vs. 0.04±0.05, respectively; p=0.006). The total rescue analgesic requirements in the first 36 postoperative hours did not significantly differ between the two groups. We conclude that following LH, the posterior TAP and ESP blocks can achieve similar levels of pain management.

Randomized comparison between transversus abdominis and erector spinae blocks in cesarean section

Introduction: Transversus abdominis plane (TAP) block provides somatic analgesia postoperatively in cesarean sections, however erector spinae plane (ESP) block has shown to provide both somatic and visceral analgesia.&#x0D; Objective: To compare the efficacy of TAP and ESP blocks for pain control after cesarean section under spinal anesthesia.&#x0D; Methods: In a double-blind superiority trial, pregnant patients undergoing cesarean section were randomized into either bilateral TAP or ESP block groups. Primary outcome was total consumption of patient-controlled analgesia (PCA) tramadol in the first 24 hours. Secondary outcomes included time required for first rescue analgesia, post-surgery visual analog score (VAS) for pain, patient satisfaction, and adverse effects.&#x0D; Results: 50 pregnant patients were randomized into TAP and ESP blocks. There was no difference in the amount of PCA tramadol within the first 24 hours between both groups [100mg (63,125) in TAP group vs 75mg (38,100) ESP group]. Pain score at rest and on movement and patient satisfaction were comparable in both groups, with no difference in adverse effects. There was a slight difference in the median time for first rescue analgesia [210min (135,315) in TAP group and 270min (225,405) ESP group] (p=0.03).&#x0D; Conclusion: TAP and ESP blocks provide similar analgesia with comparable consumption of tramadol in the first 24 hours post-cesarean section and no difference in pain scores at rest/on movement.

Prospective comparative analysis of intraoperative and postoperative anesthetic and analgesic effect of ultrasound-guided pectoral with serratus anterior plane block versus thoracic paravertebral versus erector spinae blocks in breast oncosurgeries

Abstract Aims and Objectives: Different regional anesthetic techniques have been described and are frequently used in breast cancer surgeries to provide efficient pain management and reduce the use of opioids. This study’s main goal was to use pain scores to compare the postoperative analgesic effectiveness of pectoral nerve (PECS 1) block with serratus anterior plane (SAP) block, thoracic paravertebral (TPV) block, and erector spinae plane (ESP) block. Comparing the needs for intraoperative analgesia and postoperative anesthesia was one of the secondary goals. Methods: After institutional ethical committee approval and after prospectively registering this trial with the Clinical Trials Registry of India, 25 patients were randomized and enrolled in each group (Group 1 – PECS 1 and SAP block, Group 2 – TPV group, and Group 3 – ESP group). Standard general anesthesia was administered to all the patients and the blocks, as per randomization were performed before anesthesia induction. Results: The demographic characteristics, intraoperative opioid and sevoflurane consumption, and requirement of rescue analgesia were comparable between the three groups. Pain scores at 0 and 6 h were significantly less in the TPV group when compared to the ESP group and PECS 1 with the SAP group (P = 0.005 and P = 0.006, respectively). Pain scores at 12 and 24 h were comparable between three groups. Conclusion: TPV block provides significantly better pain scores at 0 and 6 h, with comparable pain scores at 12 and 24 h, compared to PECS 1 with SAP block and ESP block with comparable adverse events.

Ultrasound-guided modified pectoral plane (PECS II) block versus erector spinae plane (ESP) block for perioperative analgesia of surgical treatment of gynecomastia

BackgroundNerve block reduces anesthetics requirement, allows faster recovery, and reduces postoperative pain. The modified pectoral plane block (PECS II) and the erector spinae plane block (ESP) have been proposed for nerve block in men undergoing breast surgery for gynecomastia.This study aimed to compare the efficacy of PECS II and ESP for perioperative analgesia in men undergoing surgical treatment of gynecomastia.We conducted a randomized clinical trial on 46 males (with ASA I and II, age range from 18 to 25 years) undergoing surgical gynecomastia treatment in a tertiary medical center. Patients were randomly allocated to receive nerve blocks with either PECS II or ESP in addition to the general anesthesia. The postoperative opioid requirement, analgesic doses, pain intensity on the VAS score, hemodynamic parameters throughout the operation, and complications were recorded and compared for both groups.ResultsPECS II group had more favorable outcomes compared to the ESP group, evident by the significantly less total morphine consumption in 24 h (6.09 vs. 14.26 mg, P ≤ 0.001) and the significantly higher effective analgesic time (6.57 vs. 4.91 h, P ≤ 0.001). In addition, there were no intraoperative or postoperative complications recorded in both groups.ConclusionsFor men undergoing elective surgical treatment of gynecomastia, the ultrasound-guided modified PECS II is superior to the ESP in terms of opioid requirement, analgesic doses, and pain intensity.

The quality of recovery after erector spinae plane block in patients undergoing breast surgery: a randomized controlled trial

BackgroundThe erector spinae plane (ESP) block has recently been shown to effectively alleviate postoperative pain and reduce opioid consumption in breast surgery patients. However, data are still limited concerning the quality of recovery in patients following this procedure.MethodsThis study was a randomized controlled trial (RCT) performed in a university hospital. We randomly allocated patients to one of three groups: ESP, SHAM, and control (CON). Procedures in the ESP and SHAM blocks were performed ipsilaterally with 0.375% ropivacaine or 0.9% saline (0.4 mL/kg). Our primary outcome was the assessment of the patient’s improvement with quality-of-recovery 40 (QoR-40) a day after surgery. Other outcome assessments included postoperative pain evaluation on the visual analog scale (VAS), 24-hour opioid consumption with patient-controlled analgesia (PCA), time to the first opioid demand, and global satisfaction with perioperative treatment.ResultsOverall, patients in the ESP group had improved QoR-40 compared to the CON group, 186 [177–193] vs. 175 [165–183] (medians and interquartile ranges). Pain severity was significantly higher in the CON group compared to the ESP group at hours 2 (38 [23–53] vs. 20 [7–32]) and 4 (30 [18–51] vs. 19 [7–25]). Moreover, we observed lower oxycodone consumption after 24 hours with the PCA pump between the ESP (4 [2–8] mg) and the CON (9.5 [5–19]) groups. Patients in the CON group used PCA sooner than those in the ESP group. Participants in the ESP group were more satisfied with treatment than those in the CON group. We found no statistical difference between SHAM and the other groups.ConclusionsCompared to the CON group, the ESP block improved the quality of recovery, alleviated pain intensity, and lowered opioid consumption in patients undergoing breast surgery. However, we did not observe this superiority in comparison with the SHAM group.Trial registrationNCT04726878.
