The Effect of Various Anesthetic . Techniques on the Thyroid Hormones

Abstract

The thyroid gland is considered to be a "stress organ", which leads one to expect a reaction to the surgical trauma. Furthermore, the thyroid is a possible target organ for the effects and side effects of anesthetics and their metabolites.

So, this gland is important to the anesthetist and must be known the changes accompanying with usage of different anesthetic techniques of general anesthesia.

The aim of the present study is to find out the effect of different anesthetic techniques on the release and metabolism of the thyroid hormones and any hemodynamic changes accompanying these changes.

In this study, six different types of general anesthesia will be examined in separate groups, each of 20 adult male patients who arc undergoing surgery for hernia repair.

Group I: This group of patients received a combination of fentanyl and midazolam.

Group II: This group of patients received a combination of ketamine and midazolam.

Group III: This group of patients received propofol.
