Modified Saddle Block vs Spinal Anesthesia for TURP

Comparison of Modified Saddle Block With Spinal Anesthesia Among Patients Undergoing Transurethral Resection of Prostate Cancer; A Randomized Control Trial at a Tertiary Care Hospital

Source: ClinicalTrials.gov · Last updated 25 Sept 2026

Brief summary (registry, in English)

After obtaining informed consent, eligible patients will be enrolled in the study. Standard monitoring will be applied in the operating room and baseline blood pressure and heart rate will be recorded. Participants will be randomly assigned to receive either spinal anesthesia or a modified saddle block using hyperbaric bupivacaine administered in the lower back. The position of the patient after injection will differ according to the assigned anesthetic technique. The level of numbness produced by the anesthesia will be assessed, and patients with inadequate anesthesia will be excluded. Blood pressure and heart rate will be monitored regularly during surgery. Any significant decrease in blood pressure will be treated with intravenous phenylephrine. Any need to change to general anesthesia during the procedure will also be recorded.
