Ultrasonography Versus Palpation for Spinal Anesthesia in Obese Parturients Undergoing Cesarean Delivery

Ultrasonography Versus Palpation for Spinal Anesthesia in Obese Parturients Undergoing Cesarean Delivery

The study will compare between preprocedural ultrasonography and the conventional palpation technique for spinal anesthesia in obese parturients undergoing elective cesarean delivery

This randomized, controlled, double-blind study will be conducted on ASA physical status II-III obese parturients with full-term singleton pregnancy undergoing elective cesarean delivery under spinal anesthesia. The study subjects will be assigned to 2 equal groups. In the ultrasonography group, lumbar spinal ultrasonography will be performed before administration of spinal anesthesia. In the palpation group, conventional palpation of the anatomical landmarks will be performed.

Inclusion Criteria:

• American Society of Anesthesiologists physical status II-III parturients
• Full term singleton pregnancy
• Body mass index ≥ 35 Kg/m2

Exclusion Criteria:

• Age < 19 years
• Women presenting in labor
• Contraindications to neuraxial anesthesia (Coagulopathy, increased intracranial pressure, or local skin infection)
