Fatal intracranial bleeding associated with prehospital use of epinephrine.
We present a case of paramedic misjudgment in the execution of a protocol for the treatment of allergic reaction in a case of pulmonary edema with wheezing. The sudden onset of respiratory distress, rash, and a history of a new medicine led the two paramedics on the scene to administer subcutaneous epinephrine. Subsequently, acute cardiac arrest and fatal subarachnoid hemorrhage occurred. Epinephrine has a proven role in cardiac arrest in prehospital care; however, use by paramedics in patients with suspected allergic reaction and severe hypertension should be viewed with caution.

Sertraline overdose.
OBJECTIVE: To determine the clinical presenting signs and symptoms in presumed overdoses of sertraline, a recently approved antidepressant. METHODS: A prospective study involving five western regional poison control centers was performed to evaluate the clinical manifestations of presumed sertraline ingestions (overdoses). Information about calls pertaining to sertraline ingestions was recorded on a standard data collection form. Data including subject age, sex, amount ingested, coingestants, time interval to evaluation, vital signs, presenting signs and symptoms, ECG abnormalities, treatment given, disposition, and length of stay in the ED were collected over a nine-month period. RESULTS: Of 42 ingestions reported, two were adverse reactions to normal doses and 40 were overdoses. Stated amounts of sertraline ingested ranged from 50 to 8,000 mg (mean 1,579 mg). Mean patient age was 35.3 years (range 1 to 69 years). Mean interval to presentation was 3.0 hours. Seventeen of the 40 patients ingested sertraline alone. Of this subgroup, ten had no sign or symptom. The most common abnormalties reported in isolated sertraline overdose were tremor, lethargy, and nausea. Less common findings included agitation, confusion, and vomiting. There was no significant morbidity in this subgroup of presumed isolated sertraline ingestion. Of the 23 patients who ingested other medications along with sertraline, four were asymptomatic. Benzodiazepines and alcohol were the most frequently coingested substances. Lethargy, nausea, dry mouth, and mydriasis were the most common features reported in this group. Treatment included lavage, activated charcoal, and observation. Twelve patients were admitted for 24-hour observation, none had an adverse outcome. Of the patients released from the ED, the mean length of stay was 3.9 hours. CONCLUSION: Sertraline is commonly taken in overdose with other medications or alcohol. The signs and symptoms that develop in association with an overdose of sertraline appear to be minor and of short duration.

Cardiotoxic drugs.
This article describes the cardiovascular effects and treatment of patients who have used cardiotoxic drugs. The discussion includes cocaine, methamphetamine, cyclic antidepressants, calcium channel blockers, beta-blockers, and digoxin. The authors review treatment controversies and emphasize the acute aspects of toxicity commonly seen in the emergency department.

The golden hour in heat stroke: use of iced peritoneal lavage.
A case of heat stroke is described in which the patient presented comatose with a rectal temperature exceeding 42.5 degrees C. Standard external evaporative cooling and iced gastric lavage failed to alter his temperature or mental status. Iced peritoneal lavage brought about a decrease in rectal temperature to 39.4 degrees C and significant improvement in mental status. The patient recovered uneventfully. Techniques of rapid cooling are discussed.

Massive verapamil ingestion: a report of two cases and a review of the literature.
This report describes two patients who were victims of massive verapamil ingestion and then reviews the available literature. Because verapamil blocks the slow calcium channels of the heart and blood vessels, the use of calcium as a treatment would be logical. In the two cases reported here, calcium was only transiently effective in maintaining cardiac output and blood pressure. Several other agents were then used and most were ineffective. This is similar to experience reported in the literature that suggests that no single agent is capable of reversing verapamil's negative inotropic, dromotropic, chronotropic, and vascular smooth muscle effects.

Carboxyhemoglobinemia caused by inhalation of methylene chloride.
Spray-paint inhalation, once a common and inexpensive source of drug abuse, is now rare. Newer organic solvents, such as methylene chloride, were thought to decrease the toxicity of aerosol solvents, but they carry unique toxicities of their own. Methylene chloride toxicity is difficult to diagnose, as early symptoms are similar to those associated with many intoxicants; however, a rising carboxyhemoglobin level, despite removal of the patient from the source of exposure, is pathognomonic. In dealing with industrial exposures or organic aerosol abuse, a carboxyhemoglobin level should be part of the initial diagnostic workup, and treatment with oxygen is mandatory until toxicity resolves.

The clinical spectrum of toxic shock syndrome.
Toxic shock syndrome (TSS) is a recently recognized acute multisystem illness that may recur. Epidemiologic links with menstruation and use of tampons have been identified. We report the cases of seven patients (six women and one man), 12 to 31 years old, seen over nine months, who met the criteria for TSS. Four were menstruating at onset. All had hypotension, fever, erythematous rash and distal desquamation. A prodrome of myalgias and diarrhea occurred in all patients. Clinical features of the acute illness included pharyngitis, conjunctivitis, leukocytosis and renal dysfunction (7), hepatobiliary abnormalities (6), mental confusion (6) and coagulopathy (4). In three patients, examination of cerebrospinal fluid showed abnormalities. The illness progressed in three patients to adult respiratory distress syndrome and significant cardiac dysfunction. Staphylococcus aureus was isolated from mucosal sites in six. The disease recurred in two. There were no deaths. Possible transmissibility was illustrated by two patients, a married couple, with simultaneous illnesses. Pathophysiologic features of TSS suggest a toxicogenic cause. Management consists of early recognition, vigorous fluid resuscitation, inotropic support as needed, discontinuation of tampon use and treatment with antistaphylococcal antimicrobic drugs.

Amphetamine toxicity: experience with 127 cases.
We present a retrospective study of 127 cases of amphetamine toxicity in an emergency department (ED). The most common presenting symptoms seen were agitation, hallucinations, suicidal behavior, and chest pain. Toxicologic analysis showed amphetamines are generally not mixed with other stimulants. The vast majority of patients did not require pharmacologic treatment in the ED. Thirteen patients (10%) required admission to the hospital. Toxic medical effects of amphetamine-related compounds seen in our patients are discussed.

Severe rhabdomyolysis with renal failure after intranasal cocaine use.
A case of acute renal failure due to rhabdomyolysis in a patient who used cocaine on a daily basis is presented. In contrast to many prior reports of renal failure occurring with cocaine-associated rhabdomyolysis, our patient did not use intravenous cocaine and did not have any evidence of trauma, seizure, hypotension, hyperthermia, hyperactivity, or coma. His creatine phosphokinase peaked at 448,000 U/liter. He was treated initially with forced diuresis and i.v. furosemide, but he became oliguric, developed pulmonary edema, and required hemodialysis. He recovered fully after 3 weeks of dialysis. The literature is reviewed in an attempt to delineate a rational approach to evaluating cocaine users at risk for rhabdomyolysis.
