An RCT: use of oxytocin drip during hysteroscopic endometrial resection and its effect on operative blood loss and glycine deficit

What Was Tested

Researchers studied Oxytocin in the context of endometriosis in this randomized controlled trial publication.

To estimate the influence of oxytocin infusion on operative blood loss and glycine deficit during hysteroscopic transcervical endometrial resection (TCRE) for abnormal uterine bleeding (AUB).

Who Took Part

By PubMed's age tags, the people studied were adults, women only.

Forty-eight women with abnormal uterine bleeding that was unresponsive to conservative medical management were randomly assigned to undergo hysteroscopic TCRE with either oxytocin infusion (group A) or saline (group B).

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Oxytocin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Neither the participants nor the staff measuring them knew who was on Oxytocin, so expectations could not easily colour the readings.

A placebo (an inactive look-alike) gave the Oxytocin group a baseline to be compared against.

Prospective, randomized, placebo-controlled study (Canadian Task Force classification I).

Intravenous Ringer's lactate solution was used during surgery.

In group B, one ampoule of saline solution was added to the Ringer's solution and run at a similar rate.

The amount of distension medium used, fluid deficit, blood levels of albumin and ethanol, hematocrit, hemoglobin, changes in serum sodium levels (Na+), and central venous pressure were compared between the groups.
