Pain management in the pediatric intensive care unit

Abstract

Critically ill pediatric patients are frequently exposed to acute, established, and chronic pain as a result of their disease processes or intensive care therapies. Despite the availability of many drugs and techniques for providing analgesia, these painful conditions are not adequately treated in a large proportion of children. This article reviews some of the reasons for provision of adequate analgesia and sedation, describes the various classes of drugs commonly used in the pediatric intensive care unit, and lists the techniques and indications for regional and topical anesthesia as well as specific clinical applications for adjuvant analgesic agents. Analgesic approaches that do not have an established record of safety and efficacy in pediatric patients are not reviewed. We propose that adequate and early analgesic interventions will minimize patient's discomfort, maintain metabolic homeostasis, and improve a patient's tolerance of intensive care unit therapies and nursing interventions. Adequate analgesia can be provided to even the sickest child using the drugs, techniques, and novel approaches reviewed.
