Arterial pressure studies during carotid angiography
British Journal of Anaesthesia
|February 1, 1977
Summary
Carotid angiography under general anesthesia rarely caused significant arterial pressure changes in 92 patients. This stability may be due to patient selection, lighter anesthesia with ventilation, and safer contrast agents.
Area of Science:
- Cardiovascular medicine
- Anesthesiology
- Radiology
Background:
- Carotid angiography is an important diagnostic procedure.
- General anesthesia can affect arterial pressure during angiography.
- Previous contrast agents like Diodone (urodione) had toxicity concerns.
Purpose of the Study:
- To evaluate arterial pressure changes during carotid angiography under general anesthesia.
- To identify factors influencing hemodynamic stability during the procedure.
Main Methods:
- Study included 92 patients undergoing carotid angiography.
- General anesthesia was administered.
- Arterial pressure was monitored.
- Controlled ventilation was employed in some cases.
Main Results:
- Marked changes in arterial pressure were infrequent in the study population.
- Factors potentially contributing to stability included patient selection, lighter anesthesia levels, and use of less toxic contrast media.
Conclusions:
- Carotid angiography under general anesthesia can be hemodynamically stable.
- Careful patient selection, optimized anesthesia, and modern contrast agents contribute to safety.
