Spinal Versus General Anesthesia on Coagulation and Fibrinolysis During Transurethral Resection of the Prostate
Effects of Spinal Versus General Anesthesia on Coagulation and Fibrinolysis in Patients Undergoing Transurethral Resection of the Prostate: A Prospective Randomized Study
調査の概要
詳細な説明
Transurethral resection of the prostate (TURP) is one of the most commonly performed surgical procedures for benign prostatic hyperplasia. Surgical trauma activates both coagulation and fibrinolytic pathways, and prostate tissue possesses unique fibrinolytic properties due to its high concentration of plasminogen activators. The anesthetic technique may modify perioperative hemostasis through its effects on the neuroendocrine stress response.
The purpose of this prospective randomized study is to compare spinal anesthesia and general anesthesia with respect to perioperative and early postoperative changes in coagulation and fibrinolysis. Venous blood samples are obtained before surgery and at 1 and 24 hours after surgery for measurement of prothrombin time, activated partial thromboplastin time, international normalized ratio, fibrinogen concentration, and D-dimer levels.

実験的:spinal anesthesia
Participants received spinal anesthesia with hyperbaric bupivacaine for elective bipolar transurethral resection of the prostate (TURP).
|
Spinal anesthesia was performed at the L4-L5 interspace using 12.5 mg of hyperbaric bupivacaine for elective bipolar transurethral resection of the prostate (TURP).
Standard intraoperative monitoring and perioperative management were applied.

アクティブコンパレータ:general anesthesia
Participants received standardized general anesthesia for elective bipolar transurethral resection of the prostate (TURP).
|
General anesthesia was induced with intravenous propofol, fentanyl, and rocuronium, and maintained with sevoflurane.
Standard intraoperative monitoring and perioperative management were applied during elective bipolar transurethral resection of the prostate (TURP).
