Total Intravenous Anesthesia (TIVA) Versus Inhalational Anesthesia at The End of Laparoscopic Obstetric Surgery Regarding Postoperative Nausea and Vomiting

Обзор

Postoperative nausea and vomiting (PONV) remain among the most common and distressing complications after general anaesthesia, with important consequences for patient comfort, satisfaction, recovery trajectories, and length of stay following surgery. The incidence of PONV is especially high after laparoscopic and gynaecological procedures due to patient- and procedure-related risk factors, making effective prevention and management a priority in perioperative care \[5,8\]. Anaesthetic technique is a recognized, modifiable determinant of PONV. Numerous clinical trials and randomized studies have demonstrated that the choice between propofol-based total intravenous anaesthesia (TIVA) and volatile inhalational maintenance can materially influence PONV incidence. Propofol-based TIVA has been repeatedly associated with lower rates of early and overall PONV compared with volatile agents in diverse surgical populations, supporting its role as an antiemetic strategy in addition to pharmacologic prophylaxis \[1,2,4,9\]. Trials specifically conducted in gynaecological and laparoscopic surgical populations report consistent reductions in nausea and vomiting with propofol maintenance compared with isoflurane or other volatile agents. These procedure-specific data are directly relevant to studies in gynecological laparoscopy, where baseline PONV risk is elevated and where anesthetic technique may yield a clinically meaningful reduction in patient morbidity \[5,8,9\]. Meta-analyses and systematic reviews pooling randomized controlled trials provide higher-level evidence that TIVA reduces the relative risk of PONV compared with volatile anaesthesia. Trial-sequential and pooled analyses estimate a clinically important risk reduction favoring TIVA, although effect sizes vary with study populations, prophylactic antiemetic regimens, and outcome time windows; these syntheses underpin the rationale for a targeted randomized comparison in the gynecological laparoscopic setting \[2,4,10\].
