Effect of Intra-Operative Intravenous Crystalloid Infusion on PostOperative Nausea and Vomiting after Diagnostic Gynaecological Laparoscopy- Comparison of 30 mL/Kg & 15 mL/Kg

Abstract

BACKGROUND Laparoscopic procedures have the advantages of minimal incision, early recovery, lesser post-operative pain and early ambulation. However, they are associated with an increased incidence of post-operative nausea and vomiting (PONV), which is all the more frequent in gynaecological laparoscopic surgeries. In our study, we have evaluated the effectiveness of intra-operative intravenous crystalloid infusion on post-operative nausea and vomiting after diagnostic gynaecological laparoscopy. METHODS Informed consent was obtained and patients were randomly divided into two groups. Group 1 received 30 mL/Kg intravenous crystalloid infusion intra operatively and group 2 received 15 mL/Kg intravenous crystalloid infusion. Incidence of nausea, incidence of emesis (retching or vomiting), the amount of rescue antiemetic used, and the haemodynamic parameters were noted in the postoperative period for 12 hours for both the groups. RESULTS Incidence of PONV was much more in group 2 in 0, 1, 2, 3, 4, 6 hours post operatively and rescue antiemetic use was much more in group 2 in total 12 hours post-operative period. There was no statistically significant difference in hemodynamic parameters between Group 1 and Group 2. CONCLUSIONS Intra-operative administration of 30 mL/Kg of crystalloid infusion significantly reduces the incidence of PONV and rescue antiemetic use compared to 15 mL/Kg crystalloid infusion in diagnostic gynaecological laparoscopy. So, it can be used as a non-pharmacological method for prophylaxis of PONV.
