Pain Management Strategies and Adverse Effects of Opioids in Patients with Neurotrauma with Acute and Chronic Pain.

Pain is prevalent and a major source of disability after a traumatic brain injury (TBI) and a spinal cord injury (SCI). With a view of reducing the pain burden in neurotrauma, this study aimed to describe the use of pain management strategies and the adverse effects of opioids in patients with TBI and SCI. We collected data at hospital discharge (T1) and at 3 months post-injury (T2). A total of 70 patients, including 49 with TBI and 21 with SCI, with a mean age of 56 years (±21.1, ±17.9) were included. Almost a third of participants with TBI (33%) and SCI (29%) had a moderate average pain intensity at T1, and most experienced mild average pain intensity at T2. At T1, 80% of participants used opioids, whereas at T2, 26% of participants with TBI and 53% of those with SCI did. The main co-analgesic used was acetaminophen, with 78% and 17% for participants with TBI and 81% and 40% for participants with SCI at T1 and T2. The most common non-pharmacological strategy in participants with TBI was rest at T1 (45%) and T2 (32%), and comfortable positioning in participants with SCI at both timepoints (81% and 53%). The two most frequent adverse effects of opioids in both populations at T1 and T2 were drowsiness (35% vs. 43%; 10% vs. 13%) and constipation (27% vs. 38%; 7% vs. 20%). Opioids remain the most widely used pain management strategy in neurotrauma. Promoting a judicious use of opioids, combined with other strategies, could help patients with neurotrauma achieve adequate and safe pain relief.
