Objective: To compare the post-operative analgesic efficacy of ultrasound-guided pectoralis type II (PECS II) block versus erector spinae (ESP) block in patients undergoing modified radical mastectomy (MRM) for breast cancer.
Study Design: Prospective observational study
Place and Duration of Study: Anesthesia Department of Combined Military Hospital, Rawalpindi, Pakistan, from Jun to Dec 2022.
Methodology: The patients were divided into the pectoralis type II block (Group PECS II) (n=25) and erector spinae block group (Group ESP) (n=25). Primary variables measured were mean time to first rescue analgesia, mean dose of nalbuphine required for control of pain in the next 24 hours, and mean HDU stay. Secondary parameters observed were patient satisfaction on the Likert scale 24 hours after the procedure and incidence of complications between both groups.
Results: Time to first rescue analgesia was longer in the PECS-II group at 355.84±12.64 minutes versus 242.32±10.83 minutes in the ESP group (p<0.001). Subsequently, the total analgesia requirement was also considerably decreased in the PECS-II group with 4.64±0.63 mg in 24 hours versus 8.08±0.90 mg in 24 hours in the ESP group (p<0.001). Mean HDU stay was also statistically significant and was less in the PECS-II versus ESP group, with a mean stay of 27.40±2.21 hours versus 30.60±5.14 hours (p=0.002).
Conclusion: The PECS-II block provides superior analgesia with a favorable adverse effect profile, providing excellent pain relief and patient satisfaction.
