title: Morphine for Intravenous Patient-Controlled Analgesia May Inhibit Delirium Tremens: A Case Report and Literature Review.
abstract: Alcoholism is common among trauma patients and often lacks the appropriate monitoring. Alcohol withdrawal syndrome (AWS), including delirium tremens (DT), can be associated with significant postoperative morbidity and mortality. However, appropriate acute pain management may protect against delirium; the administration of intravenous patient-controlled analgesia (IV - PCA) may not only alleviate pain, but also reduce the incidence of post-operative delirium. IV-PCA is widely used today; however, little attention has been paid to its influence on the development of AWS or DT post-surgery. Here we present a case in which the administration of IV-PCA may have delayed the onset of DT that interfered with postoperative care and the initiation of psychiatric consultation. The literature was reviewed to determine the potential mechanisms behind the effects of IV-PCA on the onset of AWS or DT.IV-PCA may delay the onset of DT. It is imperative to take into consideration trauma patients' psychiatric history including answers to questions on alcoholism, so that when an IV-PCA is administered and then discontinued, adequate interventions to prevent further morbidity associated with AWS and DT can be initiated in sufficient time.
