Single-injection Ultrasound-guided Erector Spinae Plane Block for Postoperative Analgesia in Patients Undergoing Open Radical Prostatectomy: A Prospective Randomized Sham-controlled Trial
Single-injection Ultrasound-guided Erector Spinae Plane Block for Postoperative Analgesia in Patients Undergoing Open Radical Prostatectomy: A Prospective Randomized Sham-controlled Trial
In the proposed study, a bilateral erector spinae plane (ESP) block [10 ml 1%lidocaine + 10 ml 0.5 % bupivacaine vs normal saline (NS)] will be performed preoperatively to patients undergoing open radical prostatectomy. Analgesic efficacy will be assessed on the numeric rating scale (NRS) along with intra- and 24 h post-operative narcotic consumption.
It has been reported that the ESP block produces effective postoperative analgesia for abdominal surgeries by relieving both somatic and visceral pain. In the present study, the investigators presume that an ESP block will decrease narcotic consumption and NRS values both intraoperatively and during the first 24 postoperative hours.
Patients will be divided into two groups:
Group LB (Lidocaine-Bupivacaine): A bilateral ESP block will be performed preoperatively (10 ml 1%lidocaine + 10 ml 0.5% bupivacaine). In addition, IV morphine patient-controlled analgesia (PCA) will be applied postoperatively for 24 hours.
Group S: A bilateral ESP block will be performed preoperatively (20 ml NS).In addition, IV morphine-PCA will be applied postoperatively for 24 hours.
Inclusion Criteria: AmericanSociety of Anesthesiologists (ASA) I-III patients between the ages of 18 and 65 who are scheduled for elective open radical prostatectomy.
