Study Design

Observational model cohort
Time perspective prospective
To detect the degree of intraoperative stress, venous blod will be drawn from one surgeon during 8 pheochromocytoma resections.
To detect the degree of intraoperative stress, venous blood will be drawn from one anesthesiologist during 8 pheochromocytoma resections.
Venous blood will be drawn from 8 patients with pheochromocytoma during tumor resection.

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: Patients with pheochromocytoma (Older than 18 years) - Exclusion Criteria: Patients younger than 18 years. Conservative treatment. -

Additional Information

Official title Evaluation of Stress Hormone Concentration During the Resection of Pheochromocytoma. Comparison of Surgeon - Anesthesiologist - Patient
Principal investigator Harald Groeben, M.D.
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.
