Ultrasound Guided Versus Land-mark Method for Spinal Anesthesia in Super Obesity Parturients

Obesity, Morbid Clinical Trial

Official title: Comparison of Ultrasound and Anatomical Landmark Method in Spinal Anesthesia for Elective Cesarean Section in Super Obese Parturients With BMI ≥ 50 kg/m2. A Randomized Controlled Trial

Status Recruiting

Clinical Trial Summary

This study will investigate whether an ultrasound-assisted technique is better than a classical land-mark technique to facilitate spinal anesthesia in the sitting position in super obese pregnant women with BMI ≥ 50 who will undergo elective cesarean section.

The primary objective of this study is the rate of successful dural puncture at the first attempt. It was assumed that ultrasound could facilitate neuraxial blockade in super obese (BMI ≥ 50 kg/m2), pregnant women, according to the Who classification, whose topographic anatomy is difficult.

Clinical Trial Description

Spinal anesthesia is the most commonly used anesthesia method for elective cesarean deliveries. Anesthesiologists may struggle to determine the poorly palpable surface landmarks in super obese (BMI ≥ 50 kg/m2) pregnant women.

The manual palpation technique, preferred in neuraxial anesthesia, may be very difficult in super obese pregnant women due to difficulty identifying bone landmarks. Neuraxial ultrasound examination before spinal anesthesia may help spinal anesthesia performance and decrease the number of attempts in obese parturients.

This study will be a single-center, prospective, randomized, double-blinded trial in a university hospital. Patients scheduled for elective cesarean will be screened for enrollment in the study. The anesthetist administering spinal anesthesia and evaluating the data were blind to the distribution of patient groups. Ultrasonographic examinations were performed by a single investigator trained in this technique who performed more than 60 ultrasound-guided neuraxial blocks. ;
