Abstract

Objective: To compare efficacy of intravenous paracetamol and fentanyl for intra-operative and post-operative analgesia in patients undergoing rigid hysteroscopy.
Method: The prospective randomised control trial was conducted at Aga Khan University Hospital, Karachi, from October 2016 to June 2017, and comprised patients aged 18-65 years with American Society of Anesthesiologists grade I or II undergoing hysteroscopy who were randomised into paracetamol group P and fentanyl group F. Anaesthesia induction technique was standardised and analgesia in group P was paracetamol 15mg/Kg administered 15-30 minutes pre-surgery, and in group F, it was fentanyl 2mcg/kg administered at induction of anaesthesia. Intra-operative pain was assessed by changes in heart rate, systolic, diastolic and mean arterial blood pressure, and post-operative pain was assessed using the visual analogue scale. Data was analysed using SPSS 19.
Results: Of the 60 patients, there were 30(50%) in each of the two groups. Baseline parameters were similar in the groups except for age differences (p<0.011). In group P, mean systolic blood pressure at 10,15, 20, 25 and 30 minutes, mean diastolic blood pressure at 20, 25 minutes, and mean arterial blood pressure at 20 minutes were statistically significant (p<0.05) compared to group F. The mean heart rate was not significant between the groups (p>0.05). Post-operative pain scores were similar at 0, 15 and 30 minutes (p>0.05). Rescue analgesia was needed in 3(10%) patients in each group on arrival in the recovery room.
Conclusions: Intravenous paracetamol offered analgesic efficacy similar to fentanyl for rigid hysteroscopy in ambulatory surgery.
