This observational study focuses on pregnant women undergoing elective cesarean delivery under spinal anesthesia. Its purpose is to compare mean arterial pressure MAP measurements taken with a blood pressure cuff on the ankle to those taken on the upper arm. The goal is to see if the ankle measurement is similar to the arm measurement, which could help improve comfort and the ability to hold the newborn skin-to-skin after birth. Participants will have blood pressure cuffs placed on both their arm and ankle. Blood pressure will be measured simultaneously at several points before entering the operating room, five minutes after spinal anesthesia, and five minutes after birth. The study also assesses maternal comfort and ease of skin-to-skin contact with each cuff through postoperative yesno questions. Additional blood pressure measurements will be taken at 10, 15, and 20 minutes after birth. Throughout the study, researchers will collect demographic information, blood pressure data, newborn health scores, and maternal comfort responses. Data will be analyzed to compare the differences between ankle and arm measurements. Participants will be monitored for any possible side effects such as bruising or skin damage. The study expects no direct benefit to participants and will last approximately 12 months.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Duration of elective cesarean delivery and recovery
Participants will have blood pressure cuffs placed on the arm and ankle. Blood pressure measurements will be taken simultaneously before surgery, after spinal anesthesia, and after birth. Maternal comfort and skin-to-skin contact ease will also be assessed through postoperative questions.
