Carotid Flow Measurements in Pregnant Women
Evaluation of the Effectiveness of Carotid Flow Measurements in Predicting Post-Spinal Hypotension in Pregnant Women
Haseki Training and Research Hospital

OBSERVATIONAL
Conditions
Summary
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
Inclusion Criteria1
- "Uncomplicated term pregnant women aged 20-40 years classified as ASA 1-2.
Exclusion Criteria11
- Those diagnosed with preeclampsia or eclampsia or with systolic blood pressure above 160

- Individuals with contraindications for spinal anesthesia
- Individuals with Ba MI over 40
- Those with a gestational age under 36 weeks or over 41 weeks
- Individuals with chronic kidney insufficiency (GRF under 60)
- Those with carotid stenosis or a history of previous cerebrovascular events
- Patients with placental anomalies
- Those initially planned for expected delivery but later switched to cesarean after being taken to trauma.
- Patients were taken to the operating room with an emergency cesarean decision
- In case of failed spinal anaesthesia, those who switched to general anaesthesia before delivery

Interventions
The 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.
