[Comparison of palonosetron-dexamethasone and ondansetron-dexamethasone for prevention of postoperative nausea and vomiting in middle ear surgery: a randomized clinical trial]

Impact of body weight-based dosing of palonosetron and ondansetron on postoperative nausea and vomiting following laparoscopic sleeve gastrectomy: a randomized, double-blind study

BACKGROUND

Postoperative nausea and vomiting (PONV) is a frequent adverse effect following laparoscopic sleeve gastrectomy. Palonosetron with a standard dosing (75 μg) schedule has been questioned due to its low efficiency in obese patients. This study aimed to investigate the effectiveness and safety of the body weight-based dosing of palonosetron in managing PONV following laparoscopic sleeve gastrectomy.

METHODS

A single-center, prospective, double-blinded randomized study was conducted between August 2021 and December 2021. Patients who underwent laparoscopic sleeve gastrectomy were prospectively recruited in the study. One hundred patients were randomly divided into palonosetron (Group P) and ondansetron (Group O). The demographic and clinical variables were recorded. The primary outcome of the study was the incidence of PONV between the two groups during the hospitalization. The secondary outcomes were the number of rescue anti-emetic and analgesic medications and the Functional Living Index-Emesis scores.

RESULTS

There were 50 patients in each group (Group P and Group O). There were significant differences in the scores of POVN, nausea, and vomiting favoring Group P. In Group P, the rate of patients using rescue anti-emetics was significantly lower. The incidence of complete response and proportion of patients with higher Functional Living Index-Emesis scores were significantly higher in patients using palonosetron.

CONCLUSIONS

The use of palonosetron significantly reduced the incidence of PONV following laparoscopic sleeve gastrectomy. There was a significant improvement in the scores of Functional Living Index-Emesis in patients using palonosetron.

Effect of Palonosetron on Physical Symptoms of Surgical Patients: A Systematic Review and Meta-Analysis

Background. Postoperative nausea and vomiting (PONV) is a typical and unpleasant physical symptom that occurs in patients after surgery, and it may be one of the most challenging elements of the recovery process. PONV can be caused by a variety of factors, including surgery itself, anesthesia, or medications. Palonosetron is a medication that is now licensed by the Food and Drug Administration for the treatment of this ailment. The efficacy of palonosetron in reducing physical symptoms in patients following surgery was investigated in this meta-analysis and comprehensive review. Methods. Following a quick search of databases such as CENTRAL, EMBASE, CINAHL, Google Scholar, the Science quotation index’s Web site, the United States clinical trial check-in, the United Kingdom clinical trial check-in, the New Zealand clinical trial check-in, and the Australia check-in, as well as outlines of major anesthesia meetings held in the previous five years, we were able to get a good start on our research. Growing adults who had surgery and were given other drugs were compared to individuals who did get palonosetron in randomized controlled trials. Results. A total of 8324 participants were recruited in 10 different clinical studies. It has been shown that palonosetron may significantly reduce the 24-hour PONV incidence and 95% confidence interval (CI) 0.41–0.86. When comparing the 6-hour and 48-hour time periods, the incidences of experiencing PONV were neither statistically different (RR: 0.82, 95% confidence interval: 0.61–1.09) or considerably different (RR: 0.60, 95% confidence interval: 0.33–1.10). Following in a similar vein, there was no significant difference between the groups in the occurrence of PONV after 48 hours (RR: 0.82, 95 percent CI: 0.59–1.14). The most often reported side effects of the medicine were headaches and dizziness, which were the most common. Regardless of the drug used, the difference in adverse reactions was not statistically significant. Conclusion. When it comes to the prevention of early PONV, it has been shown that palonosetron is more effective than other medications. Palonosetron, on the other hand, has been demonstrated to be more effective than other medications in preventing vomiting after laparoscopic surgery.
