Effect of preoperative hydration on postoperative nausea and vomiting

ABSTRACT

This study was carried out on 80 patients scheduled for laparoscopic gynaecological or surgical operations. Our aim was to assess the effect of preoperative hydration on the incidence of postoperative nausea and vomiting after laparoscopic surgery. Our patients were scheduled into two groups [40 patients each] according to the volume of preoperative fluid infused. In the control group, patients received 2ml/kg Lactated Ringer solution, where in the high infusion group, patients received 20ml/kg Lactated Ringer solution 30 min before induction of anaesthesia in the preoperative area. In the postoperative period, the episodes of nausea and vomiting were recorded during stay in the recovery room, 2h later, and after 24h. Also the number of patients who required anti-emetics or the occurrence of any adverse effects [thirst and drowsiness] was recorded. Our results showed a less incidence of postoperative nausea, vomiting and adverse effects in the high infusion group compared to the control group. We concluded that supplemental preoperative fluid load reduce the incidence of postoperative adverse clinical outcome such as nausea, vomiting, thirst, and drowsiness
