About

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

Full 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.

Enrollment: 8 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Inclusion Criteria: Patients with pheochromocytoma (Older than 18 years) -

Exclusion Criteria: Patients younger than 18 years. Conservative treatment.

Trial design

8 participants in 3 patient groups

Surgeon

Description:

To detect the degree of intraoperative stress, venous blod will be drawn from one surgeon during 8 pheochromocytoma resections.

Anesthesiologist

Description:

To detect the degree of intraoperative stress, venous blood will be drawn from one anesthesiologist during 8 pheochromocytoma resections.

Patients with pheochromocytoma

Description:

Venous blood will be drawn from 8 patients with pheochromocytoma during tumor resection.
