First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 2 times
Summary
This study looks at how weight gain during pregnancy affects spinal anesthesia in planned C-sections. Researchers will watch 200 pregnant women and record how the anesthesia works and how their bodies respond. No extra treatments or procedures are given—only routine care. The goal is to learn if weight gain changes anesthesia needs or side effects.

Who is studied
The study population consists of pregnant women aged 18 to 45 years who are scheduled for elective cesarean delivery under regional (spinal) anesthesia. All participants will be followed prospectively, and no additional intervention beyond routine clinical care will be performed. Gestational weight gain will be calculated using pre-pregnancy and pre-delivery weight records and classified according to the Institute of Medicine (IOM) 2009 guidelines.
