An assessment of morbidity in near-drowning was made from a review of emergency room and hospital records of 72 patients, ages 9 months to 20 years, who suffered near-drowning during the period January 1972 through June 1974. Fifteen patients (21% evidenced severe anoxic encephalopathy; the remainder had no detectable neurologic deficits. Hypoxemia was demonstrated in 56 patients. Severe acidosis was not present unless respiratory failure occurred. Neither electrolytes, red blood cell hemolysis, nor cardiac arrhythmias presented a problem. Respiratory complications included pulmonary edema, aspiration pneumonia, atelectasis, shock lung, pneumothorax, and pneumomediastinum. All children requiring cardiopulmonary resuscitation in the emergency room suffered anoxic encephalopathy. The occurrence of seizures, fixed and dilated pupils, flaccid extremities, and lack of response to deep pain in the emergency room had almost universal correlation with resultant severe anoxic encephalopathy, as did a submersion period of six or more minutes. The morbidity of near-drowning is significant with regard to the number of children affected and the severity of the central nervous system insult received. The statement by the American Heart Association that resuscitative efforts in children should be continued for periods longer than ten minutes needs reevaluation, since neurologic recovery did not occur in any child requiring cardiopulmonary resuscitation (CPR) in the emergency room. More importantly, new methods of cerebral resuscitation need to be developed and established. In short, medical personnel need to think in terms of cardiopulmonary cerebral resuscitation (CPCR) rather than in terms of CPR.

A 2 year-old drank from a bottle of viscous lidocaine. Coughing and choking were prompt, and seizures began within 10 to 15 seconds. Intraosseous phenobarbital 40 mg/kg stopped seizures temporarily, 30 mg/kg more plus lorazepam 20 mg/kg were needed for complete control. Suctioning of the airway revealed viscous material compatible with the drug. Bilateral hilar pneumonia ensued rapidly. The syndrome of inappropriate antidiuretic hormone secretion occurred and was countered appropriately. Intubation, performed on admission, could not be discontinued. The adult respiratory distress syndrome, characterized by a typical diffuse X-ray pattern and poor oxygenation, developed. Bilateral pneumothoraces complicated care. The patient required 14 days of extracorporeal membrane oxygenation before recovery. A lidocaine level was obtained at 4 h post-ingestion and was 0.5 micrograms/mL (2 mumol/L). The rapid onset of seizures suggests that the drug was absorbed from the pulmonary bed. This possibility is supported by the finding of viscous-lidocaine-like material in the trachea, the rapid development of aspiration pneumonia, and the development of adult respiratory distress syndrome, which has been observed in adults when lidocaine was used in the trachea for procedures.

Neurogenic pulmonary edema (NPE) is a relatively common though often subclinical complication of a variety of central nervous system insults (trauma, hemorrhage, seizures, etc.) in children and adults. The syndrome probably results from massive centrally mediated sympathetic discharge and generalized vasoconstriction, and often presents in the emergency department (ED). The symptoms are likely to be mistaken for aspiration pneumonia. Treatment consists of ventilatory support, including positive end-expiratory pressure, and aggressive measures to reduce intracranial pressure. We present four cases of NPE and review its recognition and emergent management.

We report a new case of non-familial dysautonomia. The patient was a boy with no known Jewish ancestry in whom psychomotor retardation in early infancy failed to lead to specialized evaluation. Regressive episodes of ataxia developed at the age of three and infrequent generalized seizures occurred between four and seven. Diagnosis was first considered at the age of seven after neuroparalytic keratitis developed and rapidly became bilateral. This case has remained highly unusual throughout the course since none of the commonly reported complications (swallowing disorders, aspiration pneumonia, and dysautonomic "attacks") has occurred. No life-threatening manifestations have developed. Peripheral nerve biopsy specimens showed that myelinated fibers, especially of large diameters, were abnormally scarce, and that the histogram failed to exhibit the normal bimodal aspect. Ultrastructural studies also disclosed a marked reduction in the caliber of unmyelinated fibers, whose axons were flattened or occasionally missing. No evidence of regeneration was found. The atypical clinical features in our patient are discussed.

Complex partial status epilepticus (CPSE) has rarely been reported in children. We experienced a 5-year-old girl having had an abrupt onset of complex partial seizure with a fluctuating state of consciousness and aphasia. Electroencephalogram revealed repetitive epileptiform discharges originating from bilateral temporal and parieto-occipital regions over the background of diffuse continuous slow activity. Computerized tomography of the brain showed mild atrophy without focal lesions. All the other studies including bacteriology, virology, toxicology and metabolic screening were unremarkable. Intravenous administration of diazepam was ineffective for recovery of consciousness level and cease of seizure activity. A lasting control of the status was not achieved until intravenous phenytoin and oral carbamazepine were added for one more weeks. Paroxysmal attacks of periodic apnea with subsequent hyperpneic movements occurred the fourth month after the onset of illness. She regained language on rehabilitation program. Unfortunately, the patient had recurrence four months later despite medication. Finally, she died of aspiration pneumonia and status epilepticus eleven months after the onset of the disease. Compared with the other previously documented cases of prolonged complex partial status epilepticus, this case is notable for its unusual, complicated and severe symptomatology and long duration (three more months) with poor prognosis.

We prospectively studied 56 consecutive patients with severe tricyclic antidepressant ingestion to determine the incidence of associated pulmonary complications. Among the patients meeting the entrance criteria, the mean antidepressant level was 1136 ng/ml. Other characteristics were a QRS duration of greater than or equal to 0.1 seconds in 35 (63%) and seizures in 19 (34%). Seventeen patients (30%) developed 18 abnormal chest X-ray findings which included pulmonary edema in 8 cases and aspiration pneumonia in 10. Using logistic regression, we evaluated the influence of tricyclic antidepressant level, blood pressure, QRS interval, seizures, drug co-ingestion and the use of gastric lavage vs. ipecac-induced emesis on pulmonary complications. For patients with pulmonary edema, the only significantly associated factor was hypotension on emergency department presentation. For aspiration pneumonia, no significant associations were found. Co-ingestion of another drug had no apparent influence on the development of pulmonary abnormalities. Our findings suggest that pulmonary edema and aspiration pneumonia are frequent complications of severe ingestions of tricyclic antidepressants. Pulmonary edema appears to result from hypotension or its treatment. The etiology of aspiration pneumonia is unclear. A chest X-ray should be obtained in all victims of tricyclic antidepressant overdose.

Sixty four patients who presented to the emergency department following severe acute tricyclic antidepressant (TCA) overdose (defined as an antidepressant ingestion associated with a QRS interval greater than or equal to 0.10 seconds, TCA level greater than or equal to 500 ng/mL, or grade IV coma) were prospectively evaluated to determine the incidence of hypotension and the factors associated with its development. Among these patients, the mean antidepressant level was 1,094 ng/mL. The overall frequency of admission hypotension (systolic BP less than 95 mmHg) was 34% (22 of 64 patients). Using regression analysis, systolic BP showed poor correlation with TCA level (r = -.37) and maximal QRS interval (r = -.17) following severe TCA overdose. Using multivariate analysis with a logistic regression model, the influence of BP (as well as TCA level, QRS interval, and coingestion of another drug) was evaluated on four clinical outcomes: seizures, arrhythmias, aspiration pneumonia, and pulmonary edema. The occurrence of arrhythmias and pulmonary edema was significantly associated (inversely) with hypotension (P less than .01). Seizures and aspiration pneumonia were unrelated to admission BP. These results suggest that hypotension is common after severe TCA overdose and occurs independently of TCA level and prolongation of the QRS interval. Hypotension is strongly associated with the development of arrhythmias and pulmonary edema. Seizures and aspiration pneumonia may occur regardless of initial BP.

The upper-gastrointestinal examinations of 32 patients (mean age, 11 years) with histologically proven Barrett's esophagus were reviewed to evaluate the radiologic findings in children. All patients had symptoms of chronic gastroesophageal reflux and/or esophagitis, including atypical findings such as aspiration pneumonia, seizures, and failure to thrive. Fourteen patients had other diseases that might predispose them to abnormal esophageal motility and gastroesophageal reflux. Twenty-five patients had single-contrast and seven patients had double-contrast examinations. Four patients had normal single-contrast studies; 24 had gastroesophageal reflux; 12 had strictures; 10 had esophageal ulcers; and only four had hiatal hernias. The most notable difference between the results of endoscopy and the upper-gastrointestinal studies was the rate of detection of esophageal ulcers. Ten of the patients with single-contrast studies had ulcers seen at endoscopy but not shown radiologically. No specific radiologic signs of Barrett's esophagus were found, although most of our patients had abnormal upper gastrointestinal studies.

One hundred sixty cases of self-poisoning of patients aged 15 years and older were treated on the wards of the four community hospitals of Lansing, Michigan, in 1981. Most cases (91 percent) were intentional and represented suicide attempts. The complication rate was 13.8 percent and the overdose-related mortality rate 0.6 percent. Aspiration pneumonia was the most common complication, followed by respiratory failure and seizures. No patient with a level of consciousness stage 0 or 1 in the emergency room had a major overdose-related complication with permanent sequelae, and this group represented 80 percent of the cases. One possible guideline for managing the self-poisoner is level of consciousness in the emergency room.

The anticonvulsant activity of nitrazepam (Mogadon) was studied in 31 children with various seizure patterns. Dosage ranged from 0.3 to 2.2 mg. per kg. body weight daily.Eleven of 15 children with minor motor seizures showed improvement and six obtained complete relief. Nine of 16 with miscellaneous seizures were improved, but only one was completely relieved and the other eight responded to a variable extent. In cases with more than one type of seizure, the myoclonic elements were those most often diminished, but sometimes this effect was only temporary. Side effects were transient and usually mild, consisting of drowsiness, ataxia, slurred speech and excessive secretion of mucus and saliva. However, three cases of aspiration pneumonia were encountered and may have been at least partly due to the side effects. No hematological or biochemical abnormalities were observed.The results indicate that nitrazepam is a relatively safe and effective drug in the treatment of minor motor seizures, particularly infantile spasms, and is even more useful than ACTH in this serious form of epilepsy. In older children its value is chiefly for myoclonic seizures, but the degree and duration of its effectiveness appear to be more limited.
