Postoperative pain after spinal surgery in the paediatric population.

Abstract

Postoperative pain is a major aftereffect of surgery. Especially severe occurs after extensive operations within the spine. The goal of the study was to investigate the laboratory predictive factors of intensive postoperative pain in children undergoing extensive surgery Patients and methods: We recruited 41 children, age median 13 years (IQR:10-15 years) undergoing extensive spine surgery. The subjects were divided into two groups based on the intensity of postoperative pain measured using the 10-point numerical rating scale (NRS), visual analog scale (VAS) or faces pain scale-revised (FPS-R). Patients with a score of 5 or higher were included in the study group and those with NRS of less than 5 were included in the control group. We collected detailed clinical and laboratory data before, during and after surgery. The highest intensity of pain was observed in the first 6 hours after surgery. The postoperative pain was associated with a higher drop in hemoglobin concentration and hematocrit level in peri-operative period (p=0.006 and p=0.019 respectively) as well as higher changes in mean arterial pressure during surgery. Additionally, we found that children with intensive pain had higher total protein concentration after surgery. We reported that the drop in hemoglobin and hematocrit level, fluctuation in mean arterial pressure as well as total protein concentration could be useful prognostic factors of early postoperative pain. < p > < /p >.
