Cold-water submersion results in rapidly induced hypothermia. The body's physiologic response to this insult is, in some ways, similar to that of controlled hypothermia employed in the hospital setting, with the time sequencing being greatly enhanced. The application of hypothermic techniques employed with extracorporeal heat exchange on cardiopulmonary bypass to those of cold-water submersion requires careful differentiation, especially during rewarming phases. ⋯ A child who appears asystolic, apneic, and with absence of central nervous system activity after cold-water submersion, requiring intensive resuscitative efforts, may have a favorable outcome. This does not absolutely suggest a devastating outcome as we have seen in those children "frozen alive," who are hypothermic but have been effectively resuscitated, rehabilitated, and allowed to return to normal life activities. Although combined intensive and rehabilitative efforts of the medical team are essential in the care of these children, foremost in our minds should be prevention of these accidents.

Pathophysiology of near-drowning and treatment of the child with a submersion incident.
The overall prognosis for children who have had a submersion incident is directly related to several variables including length of submersion, initial neurologic evaluation, time to first breath, initial pH, and others. Resuscitation after near drowning is unsuccessful in terms of death and neurologic deficit in 30% of those children who present to our institution. ⋯ Therefore, skilled attempts at resuscitation and management are mandatory. The understanding of the sequence of events that occur during the drowning process and the pathophysiologic consequence make it possible for health care personnel to provide aggressive therapeutic interventions that will enhance the likelihood of a normal recovery.

The continued investigation and ultimate understanding of the pathophysiologic response to thermal injury and resuscitation will potentially open new avenues of fluid management. The ultimate goal of any resuscitation regimen is the preservation of organ perfusion and function. Assurance of a smooth and adequate burn resuscitation in combination with advances in wound care and coverage, inhalation injury management, and nutritional support will continue to improve the outcome of the thermally injured patient.

In the last decade, nurses and physicians have increasingly recognized the importance of eliminating postoperative pain in speeding a patient's recovery after surgery. In an effort to improve postoperative pain management, many regional anesthetic techniques have been continued from the operating room to the recovery room, and into the intensive care and medical-surgical units. The methods have been shown to be superior to traditional modes of postoperative pain relief. ⋯ To provide optimum care, nurses must be well-versed in the different regional techniques employed and the drugs used with these techniques. They must recognize complications attributable to these procedures and the toxic potential of the local anesthetics and narcotics. Early detection of these complications is essential.

This article has discussed the phenomena of postoperative delirium in the PACU. Common causes have been reviewed and treatment strategies have been presented. Postoperative delirium is a challenging patient care problem that can jeopardize postoperative recovery. The critical care nurse who is astute to the possible causes of postoperative delirium and to treatments and interventions required will help to minimize the morbidity associated with postoperative delirium.
