Abstract

Background:Corrective surgery for scoliosis is extensive. Intraoperative neuromonitoring techniques are essential including the most basic “wake-up test” which is simple old technique and can be used if the recent evoked potentials are not available. Erector Spinae Plane block ESPB may facilitate the test by making the patient easily arousable and increasing patient comfort. Methods:Twenty-eight adolescents [Age 10-18 years] were randomly included into one of two equal groups. The Block group received intraoperative bilateral single injection ESPB 0.5 ml/kg of bupivacaine 0.25% after induction. The Control group received intraoperative intravenous fentanyl only and postoperative baseline morphine infusion.We assessed the duration of the wake-up test. Results: The Block group had shorter duration in the Wake-up test than the Control group. [minutes as median (quartiles); Block: 20 (16,25); Control: 25 (20,30), P value 0.046]. Conclusion: ESBP is simple and can facilitate the wake-up test by decreasing opioid consumption, so the patient is rapidly aroused and his response to motor requests will be reliable in addition to being aware without pain.
