What this Trial Is About
This research aims to compare blood pressure measurements taken on the ankle with those taken on the arm in pregnant women undergoing elective cesarean delivery under spinal anesthesia. The main goal is to see if the mean arterial pressure (MAP) readings from the ankle are similar to the standard arm measurements, especially five minutes after birth when skin-to-skin contact is encouraged. This observational study includes women at 35 weeks or more of pregnancy scheduled for cesarean delivery. Participants will have two non-invasive blood pressure cuffs placed simultaneously: one on the arm and one on the ankle. Measurements will be taken before neuraxial anesthesia in the waiting room, five minutes after spinal anesthesia, and five minutes after birth. The study also evaluates maternal comfort and ease of holding the newborn with each cuff by asking four yes/no questions after surgery. During the study, researchers will collect blood pressure data at these key times along with demographics and newborn information. Maternal comfort regarding the blood pressure cuffs and the ability to hold the baby skin-to-skin will be assessed. Data will be analyzed to compare blood pressure readings and understand any differences. Participation involves standard care with added ankle blood pressure monitoring and lasts from enrollment through the end of the surgery.

1 visit (in-person) before surgery for consent and eligibility confirmation
Monitoring During Elective Cesarean Delivery
Duration - On the day of surgery, during the cesarean delivery
Participants have blood pressure measured simultaneously on the arm and ankle before neuraxial anesthesia, five minutes after neuraxial anesthesia, and five minutes after birth to compare measurements and assess maternal comfort with each cuff.
1 visit (in-person) on the day of surgery including measurements before anesthesia, after anesthesia, and post-birth
