Erector spinae plane block for complete surgical anaesthesia and postoperative analgesia for breast surgeries: A prospective feasibility study of 30 cases.

BACKGROUND AND AIMS

Several regional anaesthesia techniques have been described for carcinoma of the breast surgeries in the past but all of them failed to provide adequate surgical anaesthesia and are associated with multiple complications, thus limiting their use. This prospective study was designed to assess the efficacy of erector spinae plane (ESP) block to provide complete surgical anaesthesia without general anaesthesia (GA) and postoperative analgesia in patients undergoing modified radical mastectomy (MRM) surgery.

METHODS

Thirty females of the American Society of Anaesthesiologists physical status I, II or III scheduled for MRM were included in the study to receive unilateral ultrasound-guided ESP block preoperatively (25 ml of 0.5% bupivacaine with dexamethasone 8 mg on the operating side). The primary objective of the study was to evaluate the efficacy of ESP block to provide complete surgical anaesthesia in terms of total number of cases converted to GA.

RESULTS

Our study shows that ultrasound-guided single-shot ESP block provided complete surgical anaesthesia in all the patients within an average of 31.50 minutes and an average long-lasting postoperative analgesia of 41.73 hours following MRM.

CONCLUSION

Our study proves that ESP block is a novel, predictable, secure, and safe option for carcinoma of the breast surgery. Thus, ESP block would surely provide a clinical advantage in these population group.
