Neonatal septic shock has significant morbidity and mortality with current therapeutic measures. At Children's National Medical Center, from June 1984 to October 1986, 10 of 100 patients treated with venoarterial extracorporeal membrane oxygenation (ECMO) had a documented diagnosis of septic shock. All of these infants fulfilled criteria consistent with 80% mortality using conventional intensive medical management. ⋯ The septic neonates were also at higher risk for intracranial hemorrhage than the other infants treated with ECMO (40% v 26%). The necessity for prolonged intubation after ECMO for patients with septic shock suggests that this condition may be associated with additional structural damage not seen with meconium aspiration syndrome or respiratory distress syndrome. Nevertheless, for neonatal patients with septic shock unresponsive to conventional medical management, ECMO must be considered a viable alternative treatment.

Comparative Study
Hyponatraemia and intracellular water in sepsis: an experimental comparison of the effect of fluid replacement with either 0.9% saline or 5% dextrose.
Hyponatraemia associated with sepsis is known to have an increased morbidity and mortality. The cause of this phenomenon is unknown, but may be related to dilution of the extracellular space with retained exogenous fluid. Fluid and ion redistribution across the cell membrane of striated muscle was investigated in an animal sepsis model and compared with sham controls. ⋯ These animals at the same time had significantly reduced extracellular and increased intracellular volumes compared with controls and the septic animals that received saline replacement. It is concluded that the hyponatraemia and plasma hypoosmolality that occurs in these animals is caused by a combination of intracellular shift of sodium and water, and dilution of the extracellular space, probably on the basis of physiological antidiuretic hormone (ADH) secretion. Dextrose (and by implication 4% dextrose/0.18% saline) is inappropriate, potentially dangerous, and should be avoided in these circumstances.

To investigate the prevalence of myocardial contusion associated with blunt chest trauma in the pediatric age group, all patients admitted to our institution during a 6-month period with blunt thoracic trauma severe enough to produce a pulmonary contusion or rib fracture were prospectively evaluated. Cardiac evaluation was undertaken, including a multiple-gated acquisition (MUGA) cardiac scan, serial electrocardiograms (ECG), and serum creatine phosphokinase (CPK) and CPK isoenzymes. Seven patients, ranging in age from 2 1/2 to 18 years, with rib fractures or pulmonary contusion by chest roentgenograph were identified. ⋯ This limited series suggests that cardiac contusion may occur frequently in pediatric patients who have suffered from blunt thoracic trauma significant enough to result in pulmonary contusion. An MUGA scan provides a rapid, noninvasive assessment of cardiac damage in this setting. Further studies will be required to determine the clinical significance and long-term consequences of traumatic myocardial damage in the pediatric population.

Comparative Study Clinical Trial Controlled Clinical Trial
Postoperative analgesia in children: a prospective study in intermittent intramuscular injection versus continuous intravenous infusion of morphine.
Few advancements in postoperative pain control in children have been made despite longstanding inadequacies in conventional intramuscular analgesic regimens. While overestimating narcotic complication rates, physicians often underestimate efficacious doses, nurses are reluctant to give injections, and many children in pain shy away from shots. This study prospectively focuses on the safety, efficacy, and complication rate of intermittent intramuscular (IM) versus continuous intravenous infusion (IV) of morphine sulfate (MS) in 46 nonventilated children following major chest, abdominal, or orthopedic surgical procedures. ⋯ Nurse assessment of pain correlated well with the patient and parent assessments (Pearson correlation coefficients greater than 0.6). Not only did IV infusion give better pain relief than IM injections, but there were no major complications such as respiratory depression. Minor complications in this study (nausea, urinary retention, drowsiness, vomiting, hallucinations, lightheadedness, and prolonged ileus) were not significantly different between IM and IV groups.(ABSTRACT TRUNCATED AT 250 WORDS)

An increase in the awareness of the problem of gunshot fatalities in children has occurred nationwide over the last year. Unintentional firearm deaths are more common among children and young adults. These deaths may be addressed by preventive measures beyond those available for pediatric firearm suicide and homicide. ⋯ Thirty-nine self-inflicted wounds and two shotgun blasts in the line of fire accounted for the remaining deaths. The most common anatomical injury and ultimate cause of death was cranial central nervous system (CNS) (62%), followed by chest/mediastinum (20%), abdomen (10%), and other (8%). A child who has sustained a firearm injury is more likely to know the perpetrator, be killed in the home by a readily available unsecured firearm, and die from severe head injury.
