The relationship of early pain scores and posttraumatic stress disorder in burned soldiers.
Early acute pain after injury has been linked to long-term patient outcomes, including the development of posttraumatic stress disorder (PTSD). Several studies have identified a negative correlation between early anesthetic/analgesic usage and subsequent development of PTSD. This retrospective study examined the relationship between early acute pain and severity of PTSD symptoms in soldiers with burn injuries. Of the soldiers injured in Overseas Contingency Operations who had pain scores recorded at admission to the Emergency Department, 113 had burn injuries. Of those transferred to the military burn center, 47 were screened for PTSD using the PTSD checklist-military (PCL-M) survey at least 1 month after injury. Soldiers with mild, moderate, and severe pain scores had similar Injury Severity Scores and TBSA burned (P = .339 and .570, respectively). However, there were significant differences in PCL-M scores between the mild and severe pain groups (P = .017). The pain levels positively correlated with the PCL-M score (rho = 0.41, P = .004) but not with injury severity markers (Injury Severity Score and TBSA). These data suggest that early acute pain may be related to increased PCL-M score and PTSD symptoms. The intensity of pain was not related to the injury severity, and these data also show no association between pain intensity and physiological measures, including blood pressure and heart rate. However, this is a small sample size, and many other factors likely influence PTSD development. Further study is necessary to explore the relationship between early acute pain and subsequent development of PTSD symptoms.
