BackgroundThe purpose of this study was to evaluate the effect of two different volume of crystalloid given intraoperatively on postoperative nausea and vomiting (PONV).Materials And MethodsEighty adult patients of either sex belonging to ASA I and II class undergoing elective surgeries under general anesthesia for 1-2 h were studied in this prospective, randomized double blinded study. First group (group L) (n=40) received normal saline 4 mL/kg and second group (group H) (n=40) received 10 mL/kg of normal saline. This was in excess of the fasting requirement of the patients. No propofol or antiemetic drugs were given. PONV was evaluated by verbal descriptive score (VDS) [0 = none, 1 = mild, 2 = moderate, 3 = severe, and 4 = unbearable]. Ondansetron (4 mg i.v.) was given if VDS score was 3 or more.ResultsThe median immediate PONV score was 2 and 1 in group L and H, respectively. The median 2 h PONV score in group L was 3 and in group H was 1. The median 6 h PONV score in group L was 3 and in group H was 1. The 24 h median postoperative PONV score was 1 and 0 in group L and H, respectively. In all these period of time the differences were statistically significant. The incidence of vomiting was more in group L [72.5% (29/40)] than in group H [30% (12/40)]. This was statistically significant (P=0.0003).ConclusionFrom the current study it was concluded that patients who received larger volume of crystalloid intraoperatively have lesser incidence of PONV.
