Study summary

The objective of the study is to examine the effect of the addition of intravenous dexamethasone 1.5 hours prior to induction of anesthesia on the post-operative opioid consumption, pain scores, fatigue, and recovery in patients undergoing gynecological surgery with laparotomy under general anesthesia.

This is a dose finding study with two different doses (0.1 mg/kg vs. 0.2 mg/kg) of dexamethasone to find out the optimal efficacious dose of dexamethasone with minimal side effects.

Dexamethasone has anti-inflammatory, immunomodulatory, and analgesic effects; and is superior to placebo in providing post-operative pain control, lower analgesic consumption, prevention of postoperative nausea and vomiting, lesser post-operative fatigue, and better recovery profile. No dose response study has been done. The investigators hypothesize that a higher dose of dexamethasone may have an incremental beneficial effect.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 17, 2013, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
