The primary objective of the study is to determine whether there is an association between post‑CS patient’s PACU pain score and need for first rescue analgesia on intraoperative factors while using technique of anaesthesia [general anaesthesia (GA) or regional anaesthesia (RA)], intraoperative use of different types of intravenous (IV) opioids, surgical time, type of incision and patient grading using American Society of Anaesthesiologists (ASA). The PACU parameters for data collection included NRS at time zero, then at 30, 45 and 60 min and time to first rescue analgesia and time taken to reach the score of <4 after rescue analgesia and occurrence of any side effects. This study showed that in patients undergoing CS under RA, the need for rescue analgesia was less compared to patients operated under GA in the initial 30 min in PACU. In addition, patients who were operated under GA and received IV morphine as intraoperative analgesia had better pain scores compared to patients receiving nalbuphine or tramadol.
