Clinical predictors of severe head trauma in children.

We reviewed the medical records of 55 patients who underwent a cranial computed tomographic (CT) scan for acute head trauma. The severity of head trauma was classified according to objective clinical findings as severe in 44 patients, moderate in three, and mild in eight. Thirty-seven patients (84%) with severe head trauma had a brain injury identified on CT scan. Six patients with severe head trauma had a Glasgow Coma Scale score of 12 or greater and an abnormal CT scan. All patients with mild or moderate head trauma had normal CT scans. Severe head trauma, as defined in this study, accurately identified all patients with abnormal CT scan findings. We conclude that a classification based on objective clinical findings accurately identifies the severity of head trauma. This is particularly important in evaluating patients with a Glasgow Coma Scale score of 12 or greater. A prospective study including larger numbers of patients is needed to further evaluate such a classification.

Pediatric intraosseous infusions: impact on vascular access time.

A 1-year retrospective chart review was performed to evaluate the effect of intraosseous infusions (IO) on the time required to establish vascular access in pediatric patients requiring immediate vascular access for resuscitation. Eighty-one patients were identified, including 29 pulseless and non-breathing and 52 noncardiopulmonary arrest children, who required intravenous fluids or medication for resuscitation. Comparing the results with a previous review, the IO method effectively reduced the time needed to establish vascular access in the arrested group when standard techniques failed, particularly in the child less than 2 years old. The IO method was not used effectively in the non-arrest group, as evidenced by a significantly greater mean time required to establish vascular access. There were no significant complications related to the IO procedure. Nine (50%) of the patients receiving IO fluids or medication had clinical and/or laboratory evidence that these substances reached the central circulation. Early use of IO infusion in the resuscitation is recommended for not only the arrested patient, but also the critical nonarrested patient requiring immediate vascular access.

Prehospital care of the pulseless, nonbreathing pediatric patient.

The performance of life-saving procedures by prehospital care personnel was reviewed in the cases of 114 pulseless, nonbreathing pediatric patients. Children 18 months to 18 years of age had a significantly greater chance of having prehospital endotracheal intubation and vascular access established compared to children younger than 18 months of age. For all patients, witnessed arrest and initial rhythm of ventricular fibrillation were significantly associated with survival. In the younger children, endotracheal intubation also was associated significantly with survival. Nine (8%) patients survived, and only three of the survivors were without neurologic sequelae. The number of neurologically intact survivors was too small to show a statistically significant association with these factors.

Computerized tomography in hemophiliacs with head trauma.

Intracranial hemorrhage secondary to head trauma is a major cause of morbidity and mortality in patients with bleeding disorders. Indications for head computerized tomographic scanning (CT scan) on patients with bleeding disorders who sustain head trauma are not well established. We retrospectively reviewed the medical records and head CT scan results of 21 patients with bleeding disorders. Five patients had more than one episode of head trauma. The severity of head trauma per episode was classified according to objective clinical findings as minor in 12 episodes, moderate in 12, and severe in four. In three of four patients with severe head trauma, the CT scan showed evidence of intracranial hemorrhage. In this series, all 17 patients with 24 episodes of moderate or minor head trauma had normal head CT scans. We conclude that a larger prospective study is needed to further evaluate the diagnostic value of head CT scan in hemophilia patients with minor or moderate head trauma, as defined in this study.
