Transforming care: Optimizing ERAS pathway in breast cancer surgery with latissimus dorsi flap.

This study aims to establish, execute, and assess the effectiveness of a perioperative enhanced recovery after surgery (ERAS) clinical care pathway in breast reconstruction patients with LD flap breast cancer treatment. The goal is to improve early recovery outcomes, reduce hospitalization time, and enhance patient satisfaction by implementing a standardized approach to postoperative care. This study was conducted at the University of Malaya Medical Center. The outcomes of 21 breast cancer patients who underwent autologous reconstructive breast surgery with the latissimus dorsi (LD) flap within six months before the implementation of the ERAS pathway (pre-ERAS) were compared with 26 patients who underwent the same surgery with the ultrasound-guided erector spinae plane (ESP) block for the (ERAS protocol implementation) cohort. The study was conducted from November 2019 to October 2020. The length of hospital stay, amount of analgesic usage, and incidence of postoperative nausea vomiting (PONV) were recorded. The implementation of the ERAS clinical care pathway resulted in shorter hospital stays compared with the preceding care. On average, ERAS patients were mostly discharged on Day 2 post-surgery, whereas pre-ERAS patients were mostly discharged on Day 7. ERAS patients had a lower incidence of PONV from Days 1 to 5, starting with 88.5% not experiencing the condition on Days 1 and 2 and increasing to 100% on Day 5. All pre-ERAS patients experienced PONV in the first 5days post-surgery. Fewer ERAS patients required antiemetics post-surgery (88.5%) compared with pre-ERAS patients (42.9%). The implementation of the ERAS protocol as part of clinical care in autologous reconstructive breast surgery with the LD flap can improve recovery by shortening hospital stay, decreasing the use of analgesia, and alleviating PONV.

Comparative efficacy of ultrasound-guided erector spinae plane block versus wound infiltration for postoperative analgesia in instrumented lumbar spinal surgeries

ObjectiveThis study compared the efficacy of ultrasound-guided erector spinae plane block (ESPB) and wound infiltration (WI) for postoperative analgesia in patients who underwent lumbar spinal surgery with instrumentation.MethodsIn this randomized controlled trial, 80 patients were divided into two groups: ESPB (n = 40) and WI (n = 40). Postoperative pain intensity was assessed via the visual analog scale (VAS) at multiple time points within 24 h. Additionally, opioid consumption, time to first rescue analgesia, incidence of postoperative nausea and vomiting (PONV), and patient satisfaction were evaluated.ResultsBoth ESPB and WI provided effective postoperative pain management, with no significant differences in VAS scores. However, the ESPB group demonstrated a significantly longer duration of analgesia, a shorter time to first rescue analgesia, and lower total tramadol consumption (50 ± 60 mg vs. 100 ± 75 mg; p = 0.010) than did the WI group. Furthermore, a trend toward reduced PONV incidence was observed in the ESPB group, likely due to its opioid-sparing effect.ConclusionWhile both ESPB and WI provided effective postoperative pain management, ESPB demonstrated a distinct advantage by offering a longer duration of analgesia and significantly reducing opioid consumption. These findings suggest that ESPB is more effective than WI for postoperative analgesia in lumbar spinal surgeries, providing prolonged pain relief and improving patient outcomes. Further studies are warranted to explore its long-term benefits and cost-effectiveness.Trial RegistrationClinicalTrials.govPRS: NCT06567964 Date: 08/21/2024 Retrospectively registered.

Postoperative analgesic effectiveness of ultrasound-guided bilateral erector spinae plane block vs. rectus sheath block for midline abdominal surgery in a low- and middle-income country: a randomised controlled trial.

The use of erector spinae plane block and rectus sheath block for postoperative analgesia in midline abdominal procedures is becoming more common. However, the most effective and appropriate method remains unclear. We aimed to compare the postoperative analgesic effecacy of ultrasound-guided bilateral erector spinae plane blocks with rectus sheath blocks for midline abdominal surgery in a low- and middle-income country. We allocated randomly 72 patients aged 18-65 y undergoing midline abdominal surgery to an erector spinae plane block (n = 36) or a rectus sheath block (n = 36) utilising a prospective, parallel study design. Patients, care providers and outcome assessors were blinded to the interventions. The primary outcome measures were total postoperative analgesia consumption, postoperative pain severity and time to first rescue analgesic administration. Secondary outcomes included the incidence of postoperative complications and adverse events. Of 78 patients assessed for eligibility, six were excluded, leaving 72 for analysis. Patients allocated to erector spinae plane block had a lower mean (SD) postoperative opioid consumption compared with those allocated to rectus sheath block (3.5 (8.7) morphine milligram equivalents vs. 8.2 (2.8) morphine milligram equivalents, respectively; p = 0.003). Time to first analgesic request was greater in patients allocated to erector spinae plane block compared with those allocated to rectus sheath block (mean (95%CI) 16 (13-17) h vs. 12 (11-13) h, respectively; p < 0.001). There were no block-related complications in either group. Erector spinae plane blocks are more effective than rectus sheath blocks for the management of postoperative pain following midline abdominal surgery. Integration of erector spinae plane blocks into multimodal opioid-sparing analgesic strategies after midline abdominal surgeries may promote enhanced patient recovery in low-and middle-income countries.

Ultrasound-guided erector spinae plane block in radical cystectomy: a randomized controlled study

Background &amp; Objectives: Radical cystectomy (RC) is usually performed under general anesthesia, with the management of postoperative pain being a big challenge. Various approaches have been tried, including epidural analgesia, or regional nerve blocks in addition to the intravenous patient-controlled analgesia (IV-PCA). We compared the efficacy and safety of bilateral single-injection erector spinae plane block (ESPB) with IV-PCA administered morphine to manage postoperative pain following RC. Methodology: This prospective randomized controlled clinical study was performed on 60 participants ranging in age from 21 to 65 years, both sexes, BMI 20-40 kg/m2, ASA physical status II-III, planned for elective RC. Participants were randomized into two equal groups. Group ESPB received ultrasound-guided single shot ESPB at T10 with 20 mL bupivacaine 0.25% bilaterally; IV morphine 3 mg bolus was used as rescue analgesia when the Numeric Rating Scale (NRS) pain score was ≥ 4. Group C (control group) received IV-PCA by morphine 3 mg IV when NRS pain score was ≥ 4 and repeated 1/2 mg if still pain score was recorded ≥ 4 for 15 min. Pain was measured on NRS at 2 , 4 , 8, and 12 h as well as the postoperative heart rate (HR) and mean arterial blood pressure (MAP). Complications were noted, Results: Time to first analgesic request was substantially prolonged in Group ESPB compared to Group C (P &lt; 0.001). Total postoperative consumption of morphine in 1st 48 h and postoperative nausea and vomiting were substantially reduced in Group ESPB compared to Group C (P &lt; 0.05). NRS pain scores, postoperative HR and MAP measurements were substantially reduced at 2, 4, 8, and 12 h in Group ESPB than Group C (P &lt; 0.05). Bradycardia and hypotension varied insignificantly different between both groups. Respiratory depression and urinary retention did not occur in any patient in both groups. Conclusions: Compared with IV-PCA administered morphine, bilateral single-injection ESPB was associated with better hemodynamics and analgesic properties, as observed by lower pain scores, less postoperative opioid consumption, and longer time to first analgesic request with good safety profile after radical cystectomy.

Bilateral Ultrasound-Guided Erector Spinae Plane Block for Management of Acute Postoperative Surgical Pain After Pediatric Cardiac Surgeries Through a Midline Sternotomy.

Ultrasound (US) guided erector spinae plane block (ESPB) is a safe and effective technique in providing perioperative pain management in pediatrics with a high success rate. Was to compare the efficacy of bilateral ultrasound-guided erector spinae plane block for management of acute postoperative surgical pain after pediatric cardiac surgeries through a midline sternotomy. One hundred patients aged 4-12 years were randomly assigned into two groups, both groups received general anesthesia followed by bilateral sham erector spinae plane block at the level of T6 transverse process using 0.4 ml/kg normal saline on each side in the control group (group C) or bilateral ultrasound-guided erector spinae plane block at the level of T6 transverse process using 0.4 ml/kg ropivacaine 0.2% with a maximum dose of 2 mg/kg mixed with adrenaline 2 mcg/ml in erector spinae plane block group (group E). The postoperative pain scores were evaluated immediately post-extubation, at 1 hour, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 hours after extubation, total consumption of intraoperative fentanyl and time to first rescue analgesic administration were also recorded. There was a statistically high significant delay in the group E (314.72 ± 45.94) compared with the group C (36.7 ± 7.22) as regards to the mean (SD) of the time of the rescue analgesia (P < 0.001) (with 95% CI), moreover; the number of rescue analgesic was significantly higher in the group C compared with the group E (P < 0.001) (with 95% CI) and the mean (SD) of total intraoperative and postoperative levels fentanyl requirements in the group C were significantly higher compared with the group E (6.47 ± 0.98 and 5.09 ± 0.83) (with 95% CI) in group C versus (4.69 ± 0.71 and 2.31 ± 0.66) (with 95% CI) in group E respectively (P < 0.001) (with 95% CI). Ultrasound-guided bilateral ESPB with ropivacaine and adrenaline delays the postoperative need of analgesia and reduces postoperative fentanyl consumption at 24 h in pediatric patients undergoing cardiac surgery through midline sternotomy.

Ultrasound-Guided Erector Spinae Plane Block in Elderly Patients Undergoing Total Hip Arthroplasty (THA): A Triple-blind, Randomized, Controlled Trial

BACKGROUNDTotal hip arthroplasty (THA) induces postoperative pain in elderly individuals. The erector spinae plane block (ESPB) is a novel analgesic approach for postoperative pain control. This randomized controlled trial evaluated the effectiveness of ultrasound-guided ESPB with ropivacaine in reducing pain in elderly patients undergoing THA METHODSPatients aged 60 to 80 years who had an American society of Aneshesiologists (ASA) physical status I to III were eligible for this study. There were 50 patients who were randomized into two groups: the ESPB group receiving ultrasound-guided ESPB with ropivacaine, and the control group receiving ESPB with normal saline. All patients underwent general anesthesia, and the mean arterial pressure (MAP), heart rate (HR), intraoperative opioid consumption, numerical rating scale (NRS) scores, and postoperative adverse reactions were recorded throughout the perioperative period. RESULTSA significant reduction in NRS scores was observed in the ESPB group compared to the control group at various time points, including in the recovery room and at 12 and 24 hours postoperatively (P < 0.05). When the observation period was extended to 48 hours, no significant difference in NRS scores was noted between the two groups (P > 0.05). No significant differences in MAP and HR were found between the two groups, but the ESPB group showed lower coefficients of variation (CV) for both MAP and HR. Moreover, the ESPB group demonstrated a significantly lower total remifentanil consumption than the control group. There was no significant difference in complications between these two groups (P < 0.05). CONCLUSIONSUltrasound-guided ESPB enhances the perioperative stability of mean arterial pressure and heart rate, providing effective analgesia within the initial 24 hours post-surgery, thereby reducing opioid requirements and improving overall postoperative recovery quality for elderly THA patients.

Bilateral ultrasound-guided erector spinae plane block for postoperative analgesia in paediatric idiopathic scoliosis patients undergoing posterior spine fusion surgery: a randomized controlled trial.

Major spinal surgery causes severe pain. We examined the ability of erector spinae plane block (ESPB) to alleviate pain after posterior spinal fusion (PSF) in paediatric scoliosis patients. Seventy-two patients who underwent PSF were randomized into a preoperative ultrasound-guided ESPB group or a no-block control group. The composite primary outcome was the area under the curve (AUC) of the numerical rating scale (NRS) score in the first 24h after surgery and the number of parent-controlled intravenous analgesia (PCIA) boluses administered 24h after surgery. The secondary outcomes included the NRS score, opioid consumption, rescue analgesia, adverse events, and quality of recovery. The AUC-NRS at rest was 62 (13) in the ESPB group and 89 (13) in the control group (P < 0.001). There were 15 (5) 24-h PCIA boluses administered in the ESPB group and 30 (7) in the control group (P < 0.001). Compared with those in the control group, the NRS scores at rest were lower in the ESPB group at 0, 3, 6, and 9h postoperatively, and the NRS scores during movement were lower in the ESPB group at 0, 3, 6, 9 and 12h postoperatively. The ESPB group showed a lower need for PCIA than did the control group at 0-6, 6-12, 12-18 and 1-24h postoperatively. In the ESPB group, fewer patients required rescue analgesics, and patients exhibited a higher quality of recovery. Preoperative ESPB improves postoperative analgesia in paediatric scoliosis patients who underwent PSF. ChiCTR2300074505. August 8, 2023.

Comparison of ultrasound-guided continuous erector spinae plane block versus continuous paravertebral block for postoperative analgesia in patients undergoing proximal femur surgeries.

Proximal femur fracture surgeries have become increasingly prevalent, presenting unique challenges for postoperative pain management due to patient demographics and comorbidities. Erector spinae plane block (ESPB) has emerged as a relatively safe alternative to paravertebral block (PVB). Our aim was to compare ultrasound-guided continuous ESPB with continuous PVB for postoperative analgesia in patients undergoing proximal femur surgeries under spinal anesthesia. A prospective randomized interventional study was conducted on 60 patients between 18 and 60 years of age undergoing proximal femur surgeries under spinal anesthesia with American Society of Anesthesiologists physical status I and II between January 2019 and April 2020. Patients were randomly assigned to receive either ultrasound-guided continuous ESPB (Group E, n = 30) or ultrasound-guided continuous PVB (Group P, n = 30) using a computer-generated randomization table. The mean maximum visual analog scale (VAS) score, VAS score in the first 24 h, the time of rescue analgesia, and total requirement of rescue analgesia were assessed. The maximum VAS score within the first 24 h was numerically higher in Group P but statistically insignificant (p-value 0.279). VAS scores at 0, 1, 2, 6, and 18 h postoperatively were comparable in both groups. However, at the 24-h mark, the VAS score between Group E and Group P was statistically significant (p-value 0.018) but not clinically relevant. The mean paracetamol and tramadol requirements were comparable between the two groups. Continuous ESPB is as effective as continuous PVB for postoperative analgesia in proximal femur surgeries. The enhanced safety profile of erector spinae block underscores its significance in postoperative pain management.

Simulation tools in ultrasound-guided regional anesthesia: developing a simple, inexpensive erector spinae plane (ESP) block teaching model.

The erector spinae plane (ESP) block is an increasingly utilized regional block in the emergency department, representing one effective alternative or adjunct to opioid analgesia in patients presenting with rib fractures. While there is growing interest, its widespread adoption faces hurdles, such as a lack of appropriate training resources. Gelatin-based phantoms to simulate human anatomy have been widely used to facilitate ultrasound-guided procedures, although no such model for the ESP block has yet been defined in the literature. To address this gap, we sought to design and assemble an inexpensive, simple to build, reusable phantom to simulate the sonographic anatomy of the posterior thoracic wall and serve as a task trainer for an ultrasound-guided ESP block. This novel phantom model reproduces an ultrasonographic fascial plane using a gelatin medium and 3D-printed thoracic spine with ribs allowing for needle guidance and hydrodissection.

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.

Comparison of the Efficacy Between Ultrasound-Guided Paravertebral Block and Erector Spinae Block for Postoperative Analgesia in Percutaneous Nephrolithotomy Using Levobupivacaine: A Prospective and Randomized Study.

Introduction Various techniques have been developed in the current era of regional anesthesia practice. With the advent of ultrasound, the visualization of needle and pleura in real time enables a better outcome with negligible adverse events. This study was designed to compare the efficacy between ultrasound-guided erector spinae plane block (ESPB) and paravertebral block (PVB) in percutaneous nephrolithotomy (PCNL) for the duration of postoperative analgesia with levobupivacaine, a local anesthetic with higher lipid solubility, making it more potent and resulting in a longer duration of action. Methods This prospective randomized single-blinded study enrolled 50 patients of ASA grades I and II, aged between 20 and 60 years, who were scheduled for PCNL under general anesthesia. Patients were divided into two groups of 25 each: group ESPB andgroup PVB, and 25 mL of 0.25% levobupivacaine was administered to both groups. They were primarily evaluated for the duration of postoperative analgesia. Total rescue analgesic requirements, hemodynamic parameters, and any adverse effects were also assessed. Results Both ESPB and PVB provided a significant duration of analgesia postoperatively. Demographic characteristics in both groups were comparable. The duration of postoperative analgesia in group ESPB was 746 ± 58.6 minutes when compared to group PVB, which is 768 ± 68.6 minutes (p = 0.08). Intravenous (IV) paracetamol was used as a rescue analgesic. The doses used were also comparable in both groups, with the visual analog score (VAS) being high after around 12 hours of surgery. The total rescue analgesic requirement was similar in both groups (group ESPB, 2.0 ± 1.6; group PVB, 2.2 ± 1.4; p = 0.51). There were no significant hemodynamic or other adverse effects in either group. Conclusion We conclude that both ESPBand PVB using isobariclevobupivacaine 0.25% as a local anesthetic are equally efficacious in providing effective postoperative analgesia in patients undergoing PCNL under generalanesthesia.

Comparison of Continuous Thoracic Epidural Analgesia Versus Bilateral Erector Spinae Plane Block for Pain Management in Coronary Bypass Surgery.

Background Effective pain control is vital for patients undergoing heart surgery. Utilizing a multimodal approach to analgesia is essential, as poor pain management can result in hemodynamic and systemic complications. This study aimed to compare perioperative pain management techniques in patients undergoing coronary artery bypass grafting (CABG), specifically evaluating continuous thoracic epidural analgesia and ultrasound-guided bilateral erector spinae block. Methods This randomized comparative study was conducted at a tertiary care centreover a period of six months, with approval from the institute's ethics committee. A total of 24 patients undergoing CABG under general anesthesia participated in the study. They were randomly assigned to either the continuous thoracic epidural analgesia (TEA) group (Group A) or the ultrasound-guided bilateral erector spinae plane (ESP) block group (Group B) using a simple randomization method. The study assessed intraoperative intravenous opioid requirements for maintaining stable hemodynamics, as well as postoperative resting and coughing Visual Analog Scale (VAS) scores and peak inspiratory spirometry. Results Twelve patients from each group completed the study, with comparable demographics (age, gender). Both groups exhibited similar resting and coughing VAS scores at 0, 3, 6, and 12 hours postoperatively (p > 0.05). However, at 24, 36, and 48 hours, Group A had significantly higher VAS scores compared to Group B (p < 0.05). Group A maintained an overall mean VAS score of 4 or less during rest and coughing. Peak inspiratory spirometry results were consistent between both groups (p > 0.05). Conclusion The ultrasound-guided bilateral erector spinae block provided pain control comparable to thoracic epidural analgesia, making it a viable alternative for perioperative pain management. This is particularly beneficial for CABG patients where early postoperative anticoagulant therapy is crucial for graft patency. Effective pain management also contributes to faster recovery in coronary artery bypass grafting.

Comparison of efficacy of ultrasound-guided erector spinae plane block versus thoracolumbar interfascial plane block in patients undergoing lumbar spine surgeries: A systematic review and trial sequential meta-analysis.

Existing literature does not establish the superiority of the erector spinae plane (ESP) block or the thoracolumbar interfascial plane (TLIP) block in pain relief and reducing opioid consumption in lumbar spine surgeries. This systematic review and meta-analysis was aimed to discern their relative efficacy and safety. This meta-analysis included randomised controlled trials (RCTs) comparing ESP and TLIP blocks in lumbar spine surgeries. The primary outcome was 24-h opioid consumption, and secondary outcomes were visual analogue scale (VAS) scores at 1 h and 24 h and various complications. PubMed, Central Register of Controlled Trials, SCOPUS, EMBASE databases and cross-references were electronically searched. Two authors extracted data independently, cross-checked, and analysed them using RevMan 5.4. Binary outcomes were reported as odds ratios (OR), while continuous outcomes were presented as standardised mean differences (SMDs) accompanied by 95% confidence intervals (95% CIs). Among 1107 articles, six RCTs (492 patients) were finally included. The ESP block demonstrated lower 24-h opioid consumption compared to TLIP [SMD -0.32 (95% CI: -0.50, -0.14); P < 0.001, I 2 = 83%]. At 1 and 24 h, ESPB yielded significantly lower VAS scores compared to TLIP [1 h: SMD -0.38 (95% CI: -0.57, -0.18); P < 0.001, I 2 = 83%; 24 h: SMD -0.57 (95% CI: -0.76, -0.37); P < 0.001, I 2 = 73%]. No significant difference was noted in adverse events. In comparison to the TLIP block, the ESP block has significantly lower 24-h opioid consumption and VAS scores at 1 and 24 h in patients undergoing lumbar spine surgery.

Ultrasound-guided subcostal transversus abdominis plane block versus erector spinae plane block for post-operative pain after percutaneous nephrolithotomy: A comparative observational study

In India, about 12% of the population has kidney stones, and out of these about 50% may end up with some kidney function loss or renal damage percutaneous nephrolithotomy (PCNL) is accepted as the procedure of choice for large or complex renal stones. Significant post-operative pain can occur after PCNL in first 24 hours due to distension in the renal capsule and pelvicalyceal system. The study aim was to compare the efficacy of ultrasonography guided subcostal transversus abdominis plane block with erector spinae plane block in PCNL. This observational study included 67 consecutive cases (16-65 years, ASA grade I-II) divided into 2 groups. Group A (n=33) received subcostal transversus abdominis plane (SCTAP) block and Group B (n=34) received erector spinae plane block (ESPB). Post operative pain in terms of pain scores, opioid consumption, requirement of rescue analgesic in first 24 hours was noted. Quality of recovery and any adverse events were also noted. Post-operative opioid consumption was significantly less in ESPB group (34.41 ± 27.32 mcg), compared to SCTAP Group (270.91 ± 121.41 mcg). Group B patients had better post operative quality of recovery compared to Group A patients. VAS pain scores at almost all time-points were lower in the ESPB group. ESPB provided effective postoperative analgesia and reduced fentanyl consumption postoperatively compared to SCTAP block.

The erector spinae plane block vs. usual care for treatment of mechanical back pain in the emergency department: a pilot study.

The ultrasound-guided erector spinae plane block (ESPB), traditionally utilized for thoracic regional pain control, has been reported as an effective analgesic option for mechanical back pain, renal colic, and rib fractures in the emergency department (ED). This pilot study aims to compare the effectiveness of the ESPB to usual analgesic treatment for patients presenting to the ED with mechanical back pain. A prospective, single-blind randomized controlled trial was conducted at a Canadian community hospital from March 2020 to December 2022. Adult patients presenting to the ED with mechanical back pain of at least 7 out of 10 on the Numeric Pain Rating Scale (NPRS) were randomized to receive either the ESPB or usual care. The primary outcome was the difference in NPRS score reduction at ED discharge. Secondary outcomes included ED length of stay, ED opiate use, follow-up NPRS and Brief Pain Inventory (BPI) scores, back pain-related return ED visits, and ongoing opiate use. A total of 30 patients were enrolled, with 19 randomized to the ESPB cohort and 11 to the usual care cohort. The mean NPRS reduction at ED discharge was significantly higher in the ESPB group compared to the usual care group (5.4 vs. 2.2), with a difference of 3.2 (95% confidence interval 1.4-5.1). ED opiate use was lower in the ESPB group. The ESPB also resulted in a significant reduction in ED length of stay (160min vs. 235min). There were no reported adverse effects related to the research interventions. This pilot study suggests that the ESPB may be an effective opioid-sparing analgesic option for patients presenting to the ED with mechanical back pain. NCT05982483.

Effect of Bilateral Erector Spinae Plane Block versus Fentanyl Infusion on Postoperative Recovery in Cardiac Surgeries via Median Sternotomy: A Randomized Controlled Trial

ObjectivesThe effect of ultrasound-guided Erector Spinae Plane block (ESPB) on the time to extubation is unclear. This study aimed to assess the effect of ultrasound-guided bilateral ESPB on the time to extubation in patients who had cardiac surgery through midline sternotomy. DesignRandomized controlled trial. SettingCairo university hospital and national heart institute, Egypt. ParticipantsPatients aged from 18-70 years old who underwent cardiac surgery procedure through midline sternotomy. InterventionsRecruited patients were randomized to receive either preoperative single shot ultrasound guided bilateral ESPB or fentanyl infusion. MeasurementsThe primary outcome was the time to extubation. other outcomes included: total perioperative fentanyl consumption, pain score using the numerical rating score (NRS), length of ICU stay and incidence of perioperative complications. Main resultsTwo hundred and nineteen patients were available for final analysis. In the ESPB group, the mean time of extubation was significantly shorter (159.5 ± 109.5) minutes, compared to the control group (303.2 ± 95.9) minutes, mean difference (95% CI): -143.7(-171.1, -116.3) minutes, p= 0.0001. Ultrafast track (immediate postoperative) extubation was achieved in 23 (21.1%) patients in ESPB group compared to one patient (0.9%) in the control group. The ICU stay was significantly reduced in the ESPB group (47.2 2 ± 13.3) hours compared to the control group (78.9 ± 25.2) hours, p= 0.0001. There was significant reduction in NRS in ESPB group than control group for up to 24 hours postoperatively, p =0.001. ConclusionAmong adult patients undergoing cardiac surgery through medline sternotomy, the extubation time was halved in patients who received single shot bilateral erector spinae plane block compared to patients who received fentanyl infusion.

The effect of bilateral ultrasound-guided erector spinae plane block on postoperative pain control in idiopathic scoliosis patients undergoing posterior spine fusion surgery: study protocol of a randomized controlled trial

BackgroundPosterior spinal fusion (PSF) for the correction of idiopathic scoliosis is associated with severe postoperative pain. Erector spinae plane block (ESPB) has been proposed to provide analgesia and reduce opioid consumption. We aimed to investigate the effect of bilateral ultrasound-guided single-shot ESPB on postoperative analgesia in pediatric patients undergoing PSF.MethodsThis double-blinded, randomized controlled trial will enroll 74 AIS patients undergoing elective PSF. Participants will be assigned to the ESPB group or control group at a 1:1 ratio. Patients in the ESPB group will receive ultrasound-guided bilateral ESPB preoperatively, and patients in the control group received sham ESPB using normal saline. The primary joint endpoints are the area under the curve (AUC) of numerical rating scale (NRS) score and opioid consumption in postoperative 24 h. The secondary endpoints are numerical rating scale (NRS) score and opioid consumption at postoperative 0.5, 3, 6, 9, 12, 24, 36, and 48 h, rescue analgesia, recovery outcomes, and adverse events.DiscussionAt present, studies investigating the effect of ESPB on pediatric patients are still needed. This study focuses on the effect of ESPB on pediatric patients undergoing PSF on postoperative pain control and intends to provide a new strategy of multimodal analgesia management for major spine surgery.Trial registrationChinese Clinical Trial Registry ChiCTR2300074505.
