Ultrasonography Versus Palpation for Spinal Anesthesia in Obese Parturients Undergoing Cesarean Delivery
In Brief
A clinical study evaluating Lumbar Spinal Ultrasonography, Sham Ultrasound Procedure, and 4 other interventions for Anesthesia, Spinal and 2 related conditions. Completed, enrolled 280 participants across 1 site.
Detailed Summary
The study will compare between preprocedural ultrasonography and the conventional palpation technique for spinal anesthesia in obese parturients undergoing elective cesarean delivery
Study Details
Timeline
Interventions
Ultrasonography of the lumbar spines using an 8-2 MHz curved array transducer. Identification of the intervertebral space with the best image. Marking the patient's skin with horizontal and vertical lines over the L3-L4 and L2-L3 intervertebral spaces.
Moving the ultrasound probe on the patient's back with the machine in the freeze position.
Conventional palpation of the anatomical landmarks. The line crossing the iliac crests (Tuffier line) is assumed to cross the spine at L4 spinous process or L3-L4 intervertebral space. Identification of the widest intervertebral space. Marking the patient's skin with horizontal and vertical lines over the L3-L4 and L2-L3 intervertebral spaces.
Spinal anesthesia using a 25- or 22-gauge spinal needle
Bupivacaine 12.5 mg (2.5 mL 0.5%) will be administered in the subarachnoid space
Fentanyl 15 μg will be administered in the subarachnoid space
