Study type
Interventional
Description of intervention(s) / exposure
Fifty adult male patients who were planned to undergo a transurethral prostate resection (TURP) under regional anesthesia due to benign prostate hypertrophy were included in the study with informed consent obtained from each patient. This is a prospective, randomized, and double-blind study including cases with Caudal Block (group C) or Saddle Block (GroupS) for TURP.
Group S 5% 10 mg levobupivacaine and 25micrograms fentanyl were administered to the subarachnoid space by L4-5 interspace once only for the Saddle Block. The patient was held in the sitting position with the aid of an assistant for 5-7 minutes to allow the Saddle Block to develop.
Intervention code [1] 287314 0
Treatment: Drugs
Comparator / control treatment
In caudal anesthesia group (Group C, n=25), patients were turned into a left lateral decubitus position with knees pulled up to the abdomen at 90 degrees. Following the identification of sacral corns and sacral hiatus, the site of injection was infiltrated with 2 ml of 1% lidocaine. A 7 cm long 25 G needle was introduced at an angle of 45 degrees at the vertical axis to the skin, sacrococcygeal membrane was penetrated and typically was felt that it entered a space, then the needle position was brought to a 30 degree angle to the skin and was advanced to the epidural space for 4-5 cm. After no blood was seen with aspiration, 14 ml 0.5% levobupivacaine and 25 micrograms fentanyl were injected into the epidural space in a rate of 0.5 ml/sec. The patients were placed in a neutral supine position. The patient was made to wait until a block at the T10 level was obtained. Before placing the patients into a lithotomy position, sensorial block levels were evaluated with a pinprick test. Motor block was evaluated with the Bromage scale. All these anesthetics were administered to sacral epidural space (Caudal space) once only.

Outcomes
Primary outcome [1] 289772 0
Total requirement of analgesics in the first 24 hours of the postoperative period comparison between patients administered with a Saddle Block and patients administered with Caudal Anaesthesia
Timepoint [1] 289772 0
Motor block was evaluated bromage scale after just we performed the block and at 1, 3, 5, 7, 10, 15, and 20 minutes after the block was performed Mean arterial pressure (MAP), heart rate (HR), and levels of oxygen saturation (SPO2) were recorded in every 5 minutes in the preoperative, intraoperative and early postoperative periods. Patient satisfaction was evaluated using a scale in which the patients responded to the question. comfort score, age, body mass index, and duration of the operation were recorded. After the operation finished the satisfaction scores of patients were evaluated.
Secondary outcome [1] 303214 0
the efficacy of Saddle Block and Caudal Block on the patient comfort and postoperative analgesic consumption
Timepoint [1] 303214 0
first need of analgesic drugs and the amount of analgesics consumed in the first 24 hours were recorded. Patients were followed-up on for side effects during the time period until the sensorial blockage effects of the regional anesthesia faded such as hypotension (MAP<60 mmHg), bradycardia (HR<50/min), nausea, vomiting, irritability and shivering, headache, back pain, leg pain, weakness, and urinary and fecal incontinence until discharge from the hospital
