Ultrasound guided rhomboid intercostal block: A pilot study to assess its analgesic efficacy in paediatric patients undergoing video-assisted thoracoscopy surgery

Addition of Local Anesthetic Epidural Infusion Catheter to Intravenous Opioid Analgesia for Postoperative Pain Control in Children Undergoing Video Assisted Thoracoscopic Surgery (VATS)

PURPOSE

Postoperative analgesia following minimally invasive video assisted thoracoscopic surgery (VATS) in pediatric patients may involve intravenous opioid analgesics and continuous local anesthetic infusions via an epidural infusion catheter. The use of epidural catheters may avoid systemic side effects of intravenous opioids in this vulnerable population.

DESIGN

Our primary aim was to compare total morphine equivalents (MEQ) required, and pain scores between local anesthetic epidural infusion catheters combined with intravenous opioids, versus intravenous opioids alone in pediatric patients following VATS procedure.

METHODS

Following Institutional Review Board approval, we performed a retrospective chart review of children (ages 1 month to 18 years) who underwent VATS procedure for noncardiac thoracic surgery. Based on the postoperative analgesic technique used, the study population was divided into two groups that is, epidural group and nonepidural group. Both groups received intravenous systemic opioids. The primary outcome variables were total MEQ required and pain scores in the perioperative period.

FINDINGS

Ninety-two patients were included in the study. Of these, 22 patients belonged to the epidural group versus 70 patients to the nonepidural group. There was no statistical difference in MEQ requirements or pain scores between the groups intraoperatively (P = .304), in the postanesthesia care unit (P = .166), or at postoperative time intervals of 24 hours (P = .805) and 48 hours (P = .844). The presence of infection or empyema was a significant factor for the avoidance of epidural placement by providers (P = .003).

CONCLUSIONS

There was no significant difference in the perioperative MEQ or postoperative pain scores between the epidural catheter group and the nonepidural group. More research is necessary to determine if this could be due to epidural catheter malposition and/or inadequate dermatomal coverage of surgical chest tubes.

Efficacy and safety of rhomboid intercostal block for analgesia in breast surgery and thoracoscopic surgery: a meta-analysis

BACKGROUND

Rhomboid intercostal block (RIB) is a new regional anesthesia technique that provides postoperative analgesia for breast surgery and thoracoscopic surgery. The published papers are not yet fully integrated and do not adequately address the impact and safety of the RIB on postoperative pain.

METHODS

The PubMed, Web of Science and Embase were searched from 2016 to 2021 for all available randomized controlled trials (RCTs) that evaluated the analgesic efficacy and safety of RIB after thoracic surgery and breast surgery. Random and fixed-effects meta-analytical models were used where indicated, and between-study heterogeneity was assessed. The primary outcome was Postoperative Numerical Rating Scale (NRS) scores of patients at rest recorded 0-1, 6-8, 24 h after surgery. The secondary outcomes included rate of postoperative nausea and vomiting (PONV), postoperative fentanyl consumption and presence of complications of the block.

RESULTS

From 81 records identified, four studies met our inclusion criteria, including 216 patients (RIB:108 patients; no block: 108 patients). In the primary outcome, RIB group showed significantly lower postoperative NRS at rest at first 0-1 h and 6-8 h (weighted mean difference [WMD] = -1.55; 95% confidence internal [CI] = -2.92 to -0.19; p < 0.05), (WMD = -0. 69; 95% CI = -1.29 to -0. 09; p < 0. 05). And there was no significant difference between groups in NRS at rest at 24 h (WMD = -0.78; 95% CI = -1.64 to -0.08; p = 0.77). Also, RIB group showed significantly lower postoperative NRS of breast surgery and thoracoscopic surgery at 0-1 h (WMD = -3.00; 95% CI = -3.13 to -2.87; p < 0.01), (WMD = -1.08; 95% CI = -1.98 to -0.18; p < 0.05). In the secondary outcome, the analysis also showed RIB group had significant lower of POVN rates (summary relative risk (RR) = 0.212;95%CI = 0.10 to 0.45; p < 0. 01) and the postoperative consumption of fentanyl (WMD = -57.52;95%CI = -106.03 to -9.02; p < 0. 05).

CONCLUSION

This review shows that RIB was more effective in controlling acute pain after breast surgery and thoracoscopic surgery than general analgesia. And it is a trend that RIB may be a kind of effective and safe nerve bock technology and it requires further studies.

Serratus Anterior Plane Block in Pediatric Patients Undergoing Thoracic Surgeries: A Randomized Controlled Trial

OBJECTIVE(S)

This study was designed to evaluate the efficacy and safety of serratus anterior plane block (SAPB) as an analgesic technique for thoracotomies in pediatric patients.

DESIGN

Double-blinded randomized controlled trial.

SETTING

A single-center study at Aboelrish Pediatric Hospital, one tertiary hospital of Cairo University Hospitals.

PARTICIPANTS

Seventy pediatric patients aged six months-to-three years scheduled for thoracotomies.

INTERVENTIONS

Patients were randomized into two groups, group SF and group F. Group SF received an ultrasound-guided SAPB (n = 35), whereas group F (n = 35) did not. All groups received an intraoperative fentanyl infusion (at 0.5 μg/kg /h).

MEASUREMENTS

The primary outcome was the total dose of postoperatively administrated fentanyl in the first 24 hours. The secondary outcomes included the total dose of intraoperative additional fentanyl boluses; time of the first postoperative rescue analgesia; and postoperative Face, Legs, Activity, Cry, Consolability scale (FLACC) score values.

MAIN RESULTS

The main results of this study showed that the administrated fentanyl in the 24 hours postoperatively was significantly lower in SF group than in F group (p value ˂ 0.001). In addition, significant decreases of the postoperative FLACC pain score (p value ˂ 0.001), reduction of intraoperative fentanyl consumption (p value ˂ 0.001), and delay of the first rescue analgesia (p value ˂ 0.001) were recorded in SF group in relation to F group without significant complications in both groups.

CONCLUSIONS

Serratus anterior plane block can provide a safe, effective, and easy-to-perform regional technique for children undergoing thoracotomies.
