Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Supine group

Spinal anaesthesia was administered in sitting position and then supine position was maintained.

No interventions assigned to this group

Left tilt group

Spinal anesthesia was administered in sitting position was then maintained on supine position until full anesthetic effect (motor and sensory loss) and then table was tilted 15 degrees to the left.

No interventions assigned to this group
