Landmark Versus Ultrasongraphy Guided Spinal Anesthesia in Lower Abdominal Surgeries in Cancer Patients: a Randomized Controlled Trial

Spinal anesthesia is a commonly employed technique for lower abdominal surgeries, providing effective anesthesia and analgesia with minimal systemic effects. In cancer patients undergoing such procedures, careful consideration of anesthetic techniques is crucial, given their often-compromised physiological state and the need to minimize postoperative complications. Two approaches to administering spinal anesthesia are Ultrasound (US)-guided and the traditional landmark-based technique. the aim of the study :To evaluate the efficacy, safety and feasibility of US-guided spinal anesthesia versus the landmark-based technique in cancer patients undergoing lower abdominal surgery.
