Evaluation of Plasma Catecholamine Concentration During Surgery

July 28, 2009 updated by: Kliniken Essen-Mitte

Evaluation of Stress Hormone Concentration During the Resection of Pheochromocytoma. Comparison of Surgeon - Anesthesiologist - Patient

Stress during surgery leads to significant increase in plasma catecholamine concentrations in surgeons, anesthesiologists, and patients.

Study Overview

Status

Unknown

Conditions

Detailed Description

Hypothesis: Resection of pheochromocytomas can lead to more than normal stress in surgeons and because of abrupt hemodynamic changes in patients as well in anesthesiologists. Measurements of catecholamine concentrations at baseline, prior to surgery during and after surgery, are to be performed to test this hypothesis.
