[Noninvasive hemodynamic (bioimpedance) evaluation during short anesthesia with propofol]
Minerva Anestesiologica
|January 1, 1989
Summary
Propofol anesthesia significantly reduced cardiac output and blood pressure in patients undergoing urologic procedures. Heart rate, however, remained stable during the monitored period.
Area of Science:
- Anesthesiology
- Cardiovascular Physiology
Context:
- Propofol is a common anesthetic agent.
- Minor urologic procedures require careful hemodynamic monitoring.
Purpose:
- To evaluate the hemodynamic effects of propofol (3 mg/kg) during anesthetic management.
- To assess changes in cardiac output, blood pressure, and myocardial function.
Summary:
- Noninvasive thoracic electrical bioimpedance was used to monitor 10 patients.
- Significant decreases in cardiac output, cardiac index, systolic and diastolic blood pressures, and EVI/TFI were observed within 10 minutes.
- Heart rate remained unchanged throughout the observation period.
Impact:
- Provides crucial data on propofol's cardiovascular impact in this patient population.
- Informs anesthetic management strategies for urologic procedures.
- Highlights the need for vigilant hemodynamic monitoring during propofol administration.
