Dexamethasone Palmitate for PONV After Craniotomy

Registration Number
NCT06988124
Lead Sponsor
Beijing Tiantan Hospital
Brief Summary

Dexamethasone is almost one of the most commonly used drugs for postoperative nausea and vomiting (PONV) prevention. However, PONV is still a complex problem to be solved; for example, even with preoperative dexamethasone administration, there are still some patients undergoing craniotomy still experience PONV within 24 hours postoperatively. Compared to dexamethasone, dexamethasone palmitate has a long-lasting anti-inflammatory effect, 2-5 times that of traditional water-soluble dexamethasone, with fewer adverse effects. This trial aims to assess the effect and safety of preoperative dexamethasone palmitate on PONV after craniotomy.

Primary Outcome Measures
NameTimeMethod
The incidence of PONVWithin the first 24 hours postoperatively

PONV will be defined as any nausea, emetic episodes (vomiting or retching), or both. Nausea is defined as an unpleasant sensation with an urge to vomit. Vomiting is defined as the physical event of forcefully expelling gastric contents through the mouth. Retching refers to the forced movement of gastrointestinal contents without actual expulsion of vomitus.

Secondary Outcome Measures
NameTimeMethod
The VAS scaleAt 6 hours, 24 hours, 48 hours, and 72 hours postoperatively

The VAS scale (0 = no pain to 10 = maximum pain)

Postoperative length of stay (LOS)Within 1 month postoperatively

Postoperative length of stay (LOS)

Safety outcomesWithin 1 month postoperatively

Such as hypotension, bradycardia, hypertension, tachycardia, et al.

The Incidence of PONVAt 6 hours, 48 hours, and 72 hours postoperatively

PONV will be defined as any nausea, emetic episodes (vomiting or retching), or both. Nausea is defined as an unpleasant sensation with an urge to vomit. Vomiting is defined as the physical event of forcefully expelling gastric contents through the mouth. Retching refers to the forced movement of gastrointestinal contents without actual expulsion of vomitus.

Incidence of postoperative nausea (PON) and postoperative vomiting (POV)At 6 hours, 24 hours, 48 hours, and 72 hours postoperatively

Incidence of postoperative nausea (PON) and postoperative vomiting (POV)

The number of vomiting or retching episodesWithin 6 hours, 24 hours, 48 hours, and 72 hours postoperatively

The number of vomiting or retching episodes

The severity of PONVAt 6 hours, 24 hours, 48 hours, and 72 hours postoperatively

The severity of PONV will be measured using the simplified PONV impact scoring system. The simplified PONV impact scoring system evaluates the nausea impact subscale and vomiting frequency score. Nausea impact subscale scoring will be rated by visual analogue scales (VAS) (0 = no impact to 10 = maximum impact). The VAS scores will be converted to 0-3 points via predefined thresholds. The Vomiting Frequency Score is categorized as follows: 0 for no episodes, 1 for 1-2 episodes, 2 for 3-5 episodes, and 3 for 6 or more episodes. The total score is calculated as the sum of the VAS-derived nausea impact score and the vomiting frequency score

Participant satisfaction with PONV managementAt 6 hours, 24 hours, 48 hours, and 72 hours postoperatively

Participant satisfaction will be also rated by visual analogue scales (VAS) (0 = very dissatisfied to 10 = most satisfied imaginable).

The use of rescue antiemetic drugsDuring the 0-24 hours, 24-48 hours, and 48-72 hours postoperatively

The use of rescue antiemetic drugs

The quality of postoperative recovery (QoR)At 24 and 48 hours postoperatively, discharge, and 1 month postoperatively

The quality of postoperative recovery (QoR) will be assessed by the 15-item quality of recovery scoring system \[QoR-15\]
