Dexamethasone Palmitate for PONV After Craniotomy
- Conditions
- Postoperative Nausea and Vomiting
- Interventions
- 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
Name Time Method The incidence of PONV Within 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
Name Time Method The VAS scale At 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 outcomes Within 1 month postoperatively Such as hypotension, bradycardia, hypertension, tachycardia, et al.
The Incidence of PONV At 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 episodes Within 6 hours, 24 hours, 48 hours, and 72 hours postoperatively The number of vomiting or retching episodes
The severity of PONV At 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 management At 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 drugs During 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 \[QoR-15\]
