Study Objective:
The aim of this study was to evaluate the effect of ultrasound-guided erector spinae plane (ESP) block on postoperative pain in radical prostatectomy, which leads to both visceral and somatic pain.
Design:
Prospective, randomized, placebo controlled, double-blinded.
Setting:
University hospital.
Patients:
A total of ASA I-III, 50 patients aged 18-65 who were scheduled for elective open radical prostatectomy surgery.
Interventions:
Patients were randomly allocated to receive an ultrasound-guided ESP block, with either local anesthetic (10 mL of 1% lidocaine +10 mL of 0.5% bupivacaine) or placebo bilaterally.
Measurements:
The primary outcome was morphine consumption in the first 24 h after surgery. The secondary outcomes were NRS pain scores at rest and coughing, intraoperative remifentanil consumption and need for rescue analgesic during the first 24 h after surgery.
Main Results:
Both NRS scores for post-anesthesia care unit and NRSrest scores for 1st hours were lower in Group ESPB (p < 0.001 and p = 0.033, respectively). Cumulative morphine consumption at 24 h post-surgery was similar between the groups (p = 0.447). Rescue analgesic requirement was higher in the placebo injection group than in the ESPB group at the 1st postoperative hour (p = 0.002).
Conclusions:
In open radical prostatectomies, except for the first hour, ESP block is ineffective for pain scores and on morphine consumption compared to the placebo injection group in the postoperative period.
