What this trial studies

This interventional trial compares preoperative dexamethasone palmitate with standard dexamethasone in adults undergoing elective minimally invasive endoscopic (laparoscopic or thoracoscopic) surgery under general anesthesia. Participants aged 18–65 who meet inclusion criteria will receive one of the study drugs before surgery and be followed for PONV outcomes and adverse events in the immediate postoperative period, with the primary outcome measured within 24 hours. The protocol excludes patients with recent systemic glucocorticoid use, severe organ disease, uncontrolled diabetes, pregnancy, or known allergy to dexamethasone. Safety and incidence of nausea and vomiting will be recorded to determine whether the palmitate formulation provides a longer antiemetic effect or fewer side effects than standard dexamethasone.

Who should consider this trial

Good fit: Ideal candidates are adults 18–65 scheduled for elective laparoscopic or thoracoscopic surgery under general anesthesia who can give informed consent and do not have recent systemic steroid use or severe comorbidities.

Not a fit: Patients with a dexamethasone allergy, recent systemic glucocorticoid use, uncontrolled diabetes, severe heart/liver/kidney disease, pregnancy, or breastfeeding are unlikely to participate or benefit.

Why it matters

Potential benefit: If successful, this could reduce the frequency and duration of postoperative nausea and vomiting using a longer-acting steroid with potentially fewer side effects.

How similar studies have performed: Dexamethasone is commonly used for PONV prevention and the palmitate formulation has shown longer anti-inflammatory effects in other settings, but clinical evidence specifically for PONV is limited.
