A Comparison of Mean Time to Request for First Analgesia Post-Operatively in Functional Endoscopic Sinus Surgeries (Fess) by Using Pre-Emptive Paracetamol Versus Intraoperative Paracetamol

Abstract

Objective: To compare mean time required to request for first analgesia post-operatively in functional endoscopic sinus surgeries (FESS) by using pre-emptive paracetamol versus intra-operative paracetamol. Study Design: Comparative Observational Study. Sampling Technique: Non probable, consecutive sampling Place & Duartion: This Study was conducted in the Department of Anesthesiology, Sindh employee’s social security hospital landhi Karachi, From June, 2018 to January, 2019. Materials and Methods: In this study 64 patients of both genders included. 36 patients were male and 28 were females. They were aged between 18 and 70 years. This study was conducted from June, 2018 to January, 2019. Patients were distributed into two different groups, Group-1 (pre-emptive paracetamol) and Group-2 (intra-operative paracetamol). 32 patients were included in each group. In Group-1 (pre-emptive paracetamol), patients received 1 Gm. I/V paracetamol, 15 minutes prior to induction of general anesthesia and in Group-2 (intra-operative paracetamol), patients received 1gm. I/V paracetamol just before removal of endotracheal tube. Post-operatively patients were observed in Post-Anesthesia Care Unit (PACU) with standard monitoring. Time for first request for analgesia in minutes was noted. Result: SPSS 16 version used for statistical analysis. Chi squire test applied. Mean age of in pre-emptive paracetamol group (group-1) was 51.53 + 18.90 years and mean age of patients in intra-operative paracetamol group, was 50.43 + 19.10 years (p-value 0.819). Mean weight of patients in pre-emptive paracetamol was 66.65 + 10.74 kg and mean weight of the patients in intra-operative paracetamol was 67.71 + 10.78 kg. (P-value was 0.694). ASA status 1 was found in 36 (56.30%) patients and ASA status II was found in 28 (43.80%) patients. Mean time required for first analgesia in pre-emptive paracetamol group was 192.90 + 8.70 minutes and mean time required for first analgesia in intra-operative paracetamol group was 163.93 + 13.57 minutes and p-value found < 0.001 (significant). Conclusion: Significant variance was observed in the mean time required to request for first analgesia post-operatively in functional endoscopic sinus surgeries (FESS) by using pre-emptive paracetamol versus intra-operative paracetamol. Keywords: pre-emptive versus intraoperative paracetamol, functional endoscopic sinus surgeries, time required to request for first analgesia post-operatively.
