Cardiovascular responses to pulmonary artery catheterization

Abstract

This study compares prospectively the cardiovascular and catecholamine responses to central venous and pulmonary artery catheterization before and after induction of general anaesthesia. Twenty patients for elective coronary artery surgery were randomized into two groups. One group had central venous and pulmonary artery catheterization performed awake using local anaesthesia. The other group had these catheters inserted following induction of general anesthaesia. In all patients heart rate, arterial blood pressure, ST segment analysis and epinephrine and norepinephrine

Pulmonary Artery Catheter Placement for Elective Coronary Artery Bypass Grafting: Before or After Anesthetic Induction?

“…In a study comparing placement of a PAC in a small group of anesthetized versus sedated patients undergoing elective cardiac surgery, O'Connor et al (10) showed no significant differences in hemodynamics and no differences in the stress response to PAC placement between groups. Our study showed that there was no difference in percentage change of MAP during PAC placement between groups.…”
