简要总结
Maternal hypotension during C section has been reported due to aortocaval compression (ACC) by full term uterus in supine position. This study aimed at reporting the effect of left tilt on maternal hemodynamics.
详细描述
C-section is usually done in either general anesthesia or regional (epidural or spinal) anesthesia. The choice lies with the mother. In spinal anesthesia the anaesthetic agent is injected into the subarachnoid space. Hypotension in supine position that is associated with full term gravid uterus has been explained by compression of inferior venacava (IVF) and aorta. This aortocaval compression (ACC) can also cause hypotension during C- section after spinal block.
The aim of our study was to study the effect of left tilt on systolic (SBP) and diastolic blood pressure (DBP), heart rate and the frequency of phenylephrine used to maintain the blood pressure in normal range.
