Comparison of Perioperative Analgesia between Pecs Block and Erector Spinae Block in Patients Undergoing Modified Radical Mastectomy
Abstract: Background: Breast cancer is one of the common malignancies among women and surgical resection of the tumor with axillary clearance is one of the main modalities of treatment. Various regional analgesic techniques have been described to provide analgesia after breast surgery. Pectoral plane (PECS) block is one of them in which drug is deposited in the interfascial plane among pectoralis major/minor and serratus anterior muscles. Erector spinae plane (ESP) block is a relatively novel analgesic technique in which drug is deposited beneath erector spinae muscle. Objective: To assess the onset of analgesia, extent of sensory block, intraoperative analgesic efficacy and duration of analgesia between ultrasound guided ESP block and PECS block in patients undergoing MRM and to assess the 24hour opioid requirement postoperatively in the two study groups. Methods: A total of 60 patients belonging to ASA PS I and II undergoing MRM were prospectively allocated to two groups -group E and group P. Group E (n=30) received ultrasound guided ESP block with 30ml 0.2% ropivacaine with 0.5μg/kg dexmedetomidine and group P received ultrasound guided PECS block with 30ml 0.2% ropivacaine with 0.5μg/kg dexmedetomidine, 30 minutes before induction of anesthesia. General anesthesia was administered in a standardized manner. Both groups received Tramadol 50mg IV as rescue analgesic postoperatively based on NRS pain scores. Intraoperative hemodynamics and postoperative 24 hour tramadol requirement, NRS pain scores and duration of analgesia were recorded and compared. Results: The onset of analgesia was faster in PECS block, with better dermatomal spread to T2 (22 patients in PECS block v/s 15 patients in ESP block) and increased duration of analgesia for PECS block. The postoperative 24- hour opioid requirement and pain scores were also significantly lower in patients receiving PECS block. Conclusion: Among the two regional analgesic techniques observed, PECS block has better analgesic efficacy in comparison with thoracic ESP block as evident from better pain scores and lesser postoperative opioid requirement.
