How pregnancy weight gain affects spinal anesthesia during a planned cesarean

Effect of Gestational Weight Gain on Regional Anesthesia in Cesarean Patients

Observational Elazıg Fethi Sekin Sehir Hastanesi · NCT07326644

This project will see if the amount of weight a pregnant person gains changes how spinal anesthesia works for women having an elective C-section.

What this trial studies

This is a prospective, observational, non-interventional study conducted at Fethi Sekin City Hospital in Elâzığ, Turkey. Pregnant women scheduled for elective cesarean delivery under spinal anesthesia will be enrolled and grouped by gestational weight gain according to the 2009 IOM guidelines. Study staff will record spinal block characteristics, intraoperative hemodynamic responses (such as blood pressure and heart rate), and routine perioperative outcomes using standard clinical care data. No extra procedures, medications, or interventions beyond routine care will be performed.

Who should consider this trial

Good fit: Pregnant women aged 18–45 with a single, term pregnancy scheduled for elective cesarean under spinal anesthesia who have documented pre-pregnancy and pre-delivery weights are ideal candidates.

Not a fit: People with preeclampsia, diabetes, multiple pregnancy, preterm delivery, morbid obesity (BMI ≥45), fetal anomalies, or who require conversion to general anesthesia were excluded and are unlikely to benefit from these results.

Why it matters

Potential benefit: If successful, the findings could help anesthesiologists personalize spinal anesthesia planning and monitoring based on how much weight a patient gained during pregnancy to improve safety and comfort.

How similar studies have performed: Prior research indicates maternal BMI and body habitus can affect spinal block spread and blood pressure responses, but direct evidence specifically linking IOM gestational weight gain categories to cesarean spinal anesthesia characteristics is limited.
