Comparison of intraperitoneal versus intravenous dexamethasone on postoperative nausea and vomiting after gynecological laparoscopy: a randomized clinical trial.

ABSTRACT: BACKGROUND:Postoperative nausea and vomiting (PONV) is a common complication following laparascopic surgery. This study compared the effect of intraperitoneal versus intravenous dexamethasone for reducing PONV after gynecological laparoscopic surgeries. METHODS:Eighty adult female patients, American Society of Anesthesiologists physical status I-II, scheduled for gynecological laparoscopic surgery were randomized to receive 8 mg dexamethasone intravenously (IV) (n = 40) or intraperitoneally (IP) (n = 40). The primary outcome was the PONV incidence during the first 24 h after laparoscopy. Secondary outcomes included visual analogue scale (VAS) pain scores, total rescue analgesic consumption during the first 24 h postoperatively, the need for rescue antiemetic drugs, and the incidence of complications that may accompany these medications. RESULTS:Eleven women (27.5%) in the IV group, versus only 3 (7.5%) women in the IP group, experienced nausea during the first 24 h postlaparoscopy (P = 0.037). However, 5 patients (12.5%) in the IV group, versus only 2 patients (5.0%) in the IP group, experienced vomiting (P = 0.424). No statistically significant differences were seen in the severity of nausea or the need for rescue antiemetics. The IV group had a higher rate of side-effects than the IP group (27.5% vs. 7.5%, P = 0.037). Headache and dizziness were common side effects in the IV dexamethasone group. The groups did not differ significantly in terms of mean VAS score for pain and total meperidine consumption during the first 24 h postoperatively. CONCLUSIONS:Intraperitoneal dexamethasone at a dose of 8 mg at the end of gynecological laparoscopy reduces the incidence of postoperative nausea.

Project description:Objectives To determine whether preoperative dexamethasone reduces postoperative vomiting in patients undergoing elective bowel surgery and whether it is associated with other measurable benefits during recovery from surgery, including quicker return to oral diet and reduced length of stay.Design Pragmatic two arm parallel group randomised trial with blinded postoperative care and outcome assessment.Setting 45 UK hospitals.Participants 1350 patients aged 18 or over undergoing elective open or laparoscopic bowel surgery for malignant or benign pathology.Interventions Addition of a single dose of 8 mg intravenous dexamethasone at induction of anaesthesia compared with standard care.Main outcome measures Primary outcome: reported vomiting within 24 hours reported by patient or clinician.Secondary outcomesvomiting with 72 and 120 hours reported by patient or clinician; use of antiemetics and postoperative nausea and vomiting at 24, 72, and 120 hours rated by patient; fatigue and quality of life at 120 hours or discharge and at 30 days; time to return to fluid and food intake; length of hospital stay; adverse events.Results 1350 participants were recruited and randomly allocated to additional dexamethasone (n=674) or standard care (n=676) at induction of anaesthesia. Vomiting within 24 hours of surgery occurred in 172 (25.5%) participants in the dexamethasone arm and 223 (33.0%) allocated standard care (number needed to treat (NNT) 13, 95% confidence interval 5 to 22; P=0.003). Additional postoperative antiemetics were given (on demand) to 265 (39.3%) participants allocated dexamethasone and 351 (51.9%) allocated standard care (NNT 8, 5 to 11; P<0.001). Reduction in on demand antiemetics remained up to 72 hours. There was no increase in complications.Conclusions Addition of a single dose of 8 mg intravenous dexamethasone at induction of anaesthesia significantly reduces both the incidence of postoperative nausea and vomiting at 24 hours and the need for rescue antiemetics for up to 72 hours in patients undergoing large and small bowel surgery, with no increase in adverse events.Trial registration EudraCT (2010-022894-32) and ISRCTN (ISRCTN21973627).

Project description:Postoperative nausea and vomiting (PONV) is one of the most common adverse outcomes after strabismus surgery. The primary outcome of this prospective, randomized, double-blind study was to compare the incidences of nausea or vomiting, and patient satisfaction of ondansetron and ramosetron after strabismus surgery under general anesthesia. The secondary outcome was to investigate whether the number of involved extraocular muscles (EOMs) in strabismus surgery was related to PONV.One hundred and five patients (aged 18-60 years) undergoing strabismus surgery were allocated randomly to one of the three groups: placebo, ondansetron, or ramosetron. Patients received 2 ml placebo, 4 mg ondansetron, or 0.3 mg ramosetron at the end of surgery. Each of the three groups was subdivided into two subgroups according to the number of EOMs involved in the surgery: subgroup S, single-muscle correction; subgroup M, multiple-muscle correction. The incidences of nausea or vomiting, and patient satisfaction at 2, 24 and 48 h after surgery were analyzed as primary outcome. With regard to subgroups S and M in the placebo, ondansetron and ramosetron groups, incidences of nausea or vomiting, and patient satisfaction at 2, 24 and 48 h after surgery were analyzed as seconadary outcome.The incidence of nausea was significantly lower in the ramosetron group at 2 h (9.4 %) than in the placebo (45.2 %) and ondansetron (34.7 %) groups (P < 0.05). The incidence of nausea was also significantly lower in the ramosetron group at 24 h than in the other groups (P < 0.05). Patients in the ramosetron group were more satisfied at 2 h (8.11 ± 0.98) and 24 h (8.50 ± 0.67) after surgery than those in the other groups (P < 0.05). With regard to subgroups S and M in the placebo, ondansetron and ramosetron groups, there were no significant differences in either the incidence of nausea or patient satisfaction.Ramosetron has superior antiemetic activity to ondansetron in adult strabismus surgery patients. The number of EOMs involved in strabismus surgery was not related to the incidence of PONV.Clinical Research Information Service (CRiS) Identifier: KCT0000688 .
