Transversalis Fascia Plane Block Versus Intrathecal Dexmedetomidine in Patients Undergoing Cesarean Section

Cesarean section (CS) is a commonly performed major surgical procedure that results in substantial postoperative pain and patient dissatisfaction. Spinal anesthesia is commonly used in CS surgery. However, it may be associated with several side effects, particularly hypotension. Dexmedetomidine is an α2 adrenergic receptor agonist that has an analgesic effect. Ultrasound-guided interfascial plane blocks are often used in multimodal analgesia regimens. Local anaesthetic injection into the transversalis fascia plane (TFP) anesthetizes the proximal branches of T12 and L1 which targeted in the plane between the transversus abdominis muscle and the transversalis fascia.
