The impact of ultrasound-guided bilateral rectus sheath block in patients undergoing cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy - a retrospective study

Effect of Rectus Sheath Block on Postoperative Quality of Recovery After Transabdominal Midline Gynecological Surgery: A Randomized Controlled Trial

Introduction

Rectus sheath block is an emerging technique that provide effective perioperative analgesia and is related to lower perioperative opioid consumption and decrease opioid-related adverse effects. The present research is designed to explore the effect of rectus sheath block on recovery quality in patients following transabdominal midline gynecological surgery.

Methods

Ninety female patients following elective transabdominal midline gynecological surgery were enrolled. Patients were randomized to group R (n = 45) which receive preoperative ultrasound-guided RSB with 0.4% ropivacaine or group C which is control group (n = 45). The primary outcome was the quality of recovery on the first postoperative day. The quality of recovery was assessed by the 40-item Quality of Recovery questionnaire (QoR-40). Secondary outcomes included the intraoperative opioid consumption, time to first flatus and time to first discharging from bed, postoperative nausea and vomiting, and patient satisfaction.

Results

The patients in two groups had comparable baseline characteristics. Postoperative global QoR-40 scores were significantly better in group R than in group C (165.0[159.5-170.0] vs 155.0[150.0-157.0], respectively; median difference 12[95% confidence interval: 8-15, P<0.001]). Preoperative RSB reduced intraoperative opioid consumption, reduced the time to first flatus, time to first discharging from bed and the post anaesthesia care unit discharge time. Furthermore, group R showed greater patient satisfaction.

Conclusion

A single preoperative administration of RSB with ropivacaine improved the quality of recovery in patients following transabdominal midline gynecological surgery.

Analgesic efficacy of erector spinae plane block in patients undergoing major gynecologic surgery: A randomized controlled study

STUDY OBJECTIVE

To investigate the analgesic efficacy of erector spinae plane block (ESPB) in major gynecologic surgery, expressed as cumulative opioid consumption 24 h after surgery.

DESIGN

A single-center, patient-assessor blinded, randomized controlled study.

SETTING

Samsung medical center (tertiary university hospital), between February 2022 to January 2023.

PATIENTS

Eighty-eight females undergoing major surgery with long midline incision for gynecologic malignancy.

INTERVENTIONS

Patients were randomly assigned to receive standard systemic analgesia (Control group) or ESPB (ESPB group). ESPB was performed bilaterally at the level of the 9th thoracic vertebra with a mixture of 20 mL of 0.5% ropivacaine and 100 μg of epinephrine.

MEASUREMENTS

The primary outcome was cumulative opioid consumption at 24 h postoperatively. Secondary outcomes included opioid consumption and pain severity during the 72 h after surgery. The variables regarding postoperative recovery and patient-centered outcomes were compared.

MAIN RESULTS

The mean cumulative opioid consumption 24 h after surgery was 35.8 mg in the ESPB group, which was not significantly different from 41.4 mg in the control group (mean difference, 5.5 mg; 95% CI -1.7 to 12.8 mg; P = 0.128). However, patient satisfaction regarding analgesia was significantly higher in the ESPB group compared with the control group at 24 h postoperative (median difference, -1; 95% CI -3 to 0; P = 0.038). There were no significant differences in the variables associated with postoperative recovery.

CONCLUSION

ESPB did not reduce opioid consumption during the 24 h postoperative but attenuated pain intensity during the early period after surgery.

Erector Spinae Plane Catheters for Analgesia for Cytoreduction Surgery With Hyperthermic Intraperitoneal Chemotherapy: A Case Series

Cytoreduction surgery with hyperthermic intraperitoneal chemotherapy is a complex and painful procedure that can cause postoperative hypotension and coagulopathy. Epidural analgesia may worsen hypotension and is contraindicated in the setting of coagulopathy. While alternative regional techniques are being explored, the use of erector spinae plane blocks has not been reported. We present a case series of 6 patients who had erector spinae plane catheters for cytoreduction surgery with hyperthermic intraperitoneal chemotherapy. They remained stable intraoperatively and had adequate pain control postoperatively. Erector spinae plane catheters may be a suitable alternative for epidural analgesia for these patients.
