Analgesic Potentials of Preoperative Oral Pregabalin, Intravenous Magnesium Sulfate, and their Combination in Acute Postthoracotomy Pain.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

The objective of this study was to investigate the effects of the preoperative combination of oral Pregabalin and intravenous (IV) magnesium sulfate as analgesic adjuvants in postthoracotomy pain.

Who Took Part

By PubMed's age tags, the people studied were children, both men and women.

One hundred twenty patients with American Society of Anesthesiologists physical status II were allocated randomly into 1 of 4 groups.

In the first 24 hours postoperatively, total morphine consumption, the Visual Analog Scale (0 to 10)-used as a pain measurement tool-and postoperative nausea and vomiting were assessed.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Blinding on both sides kept the participants and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

All medications were given 1 hour before surgery in all groups.

What Was Measured

PubMed files the paper under topics including Administration, Intravenous, Analgesia, Patient-Controlled, Analgesics, Magnesium Sulfate, Morphine, Postoperative Pain and Postoperative Nausea and Vomiting.
