About this trial
The goal of this observational study is to reveal the relation between carotid flow changes and post-spinal hypotension in pregnant women between the ages of 20-40. The main question it aims to answer is:
Do the carotid flow blood flow measurements and corrected flow time change before and after spinal anaesthesia related to postspinal hypotension? Participants are already receiving spinal anaesthesia to receive a caesarean section. As part of their regular anaesthesia management protocol, they will answer questions about anaesthesia management. The participants will only examined by ultrasound twice.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
"Uncomplicated term pregnant women aged 20-40 years classified as ASA 1-2.
Disqualifiers
Those diagnosed with preeclampsia or eclampsia or with systolic blood pressure above 160

Case-control
Time perspective
Prospective
Treatments tested in this trial
carotid ultrasound
Other interventionThe investigator will perform a carotid ultrasound just 2 cm before the carotid bulb and measure the corrected flow time and flow using Doppler and pulse wave analysis. The corrected carotid flow time will be calculated according to Bazett's equation.

Trial outcomes
Primary outcomes

postspinal hypotension
Hypotension is defined as (1) a decrease in systolic blood pressure \>30% or a decrease in mean arterial pressure (MAP) \>20% from baseline, or (2) systolic blood pressure \<90 mmHg or MAP \<65 mmHg.
