Overdose of pentazocine (Talwin), an agonist/antagonist opioid analgesic, is relatively uncommon. Fifty-seven cases occurring over ten years are reported. Twenty-three patients (40%) had ingested only pentazocine and did not have the classic opioid toxidrome of CNS and respiratory depression with miosis. Most patients were awake, and no patient had a respiratory rate below 12/minute. Other findings included: grand mal seizures, hypertension, hypotonia, dysphoria, hallucinations, delusions, and agitation. Eleven of 23 patients received IV naloxone (0.4-2.4 mg), but only two showed improvement. Thirty-four patients (60%) had coingested pentazocine with one to five additional substances. Patients who had ingested pentazocine with alcohol, a sedative/hypnotic drug, or an antihistamine, showed increased toxicity, including apnea, deep coma, and recurrent seizures. One patient developed opioid pulmonary edema. One patient died. Three of five patients with coma and inadequate respirations responded to IV naloxone in doses of 0.4 to 1.2 mg.

Nine children, hospitalized for severe respiratory failure following scorpion envenomation, were a part of a group of 61 youngsters and infants admitted to the Pediatric Intensive Care Unit of the Soroka Medical Center, Beer-Sheva during the years 1983-87 because of scorpion venom intoxication. Four out of the nine had cardiogenic shock, three had severe systemic hypertension and one had severe airway obstruction. All nine patients had central nervous system manifestations, including lethargy, confusion and agitation (three cases), and markedly reduced level of consciousness (six cases). Hemodynamic studies performed in two patients showed 'high pressure' (cardiogenic) pulmonary edema. Seven patients recovered completely, one died and another one was left severely handicapped. Hydralazine i.v. showed a remarkable effect on the systemic blood pressure and central nervous system disturbances in addition to mechanical ventilation. Based on our own experience and previous clinical and experimental studies, the possible pathogenetic mechanisms underlying the respiratory and central nervous system dysfunction following scorpion sting are discussed.

Water intoxication from intravascular absorption of non-electrolyte irrigating fluid is a well-known and often serious complication of transurethral resection of the prostate. The amount of absorbed fluid depends on the duration of the operative procedure, the number of transected open venous sinuses and the hydrostatic pressure of the irrigating fluid. Arterial hypertension, bradycardia, mental agitation, confusion, headache, nausea, dyspnoea, convulsions and pulmonary edema are the typical syndromes. In this case, severe Angina Pectoris was the first alarming symptom.

Methyl bromide (MeBr) is used as an insecticide fumigant. Four deaths and three recent hospitalizations have resulted from exposures to MeBr in Dade County, FL. Six cases occurred during burglaries of tented houses over a nine-month period. In four lethal exposures, the symptoms of nausea, vomiting, and malaise preceded fulminant respiratory failure. Two of these also had seizures, delirium, and agitation. Serum or plasma bromide ion levels ranged from 40 to 583 mg/L. Pulmonary edema, hyaline membranes, and hemorrhagic alveolitis were present at autopsy along with varying degrees of cerebral edema. The nonlethal exposures resulted in symptoms of conjunctival irritation, headache, or nausea. Plasma bromide concentrations varied between 17.5 and 321 mg/L. Methyl bromide characteristics, use, morbidity, and mortality in Florida during the past 25 years are reviewed. Remedies for illegal entry are proposed.

This case series illustrates the use of a suction catheter to guide the passage of an endotracheal (ET) tube through the glottis, a technique modification which can be used when standard nasotracheal intubation is unsuccessful. The technique is appropriate for patients in whom airway management is urgent, but not emergent. Catheter-assisted nasotracheal intubation is useful when intubation is difficult because of excessive patient resistance to movement of the ET tube within the oropharynx. The clinical use of this technique is described for the following scenarios: overdose with obtundation, multiple trauma with agitation, and respiratory failure from pneumonia and pulmonary edema.

Post-treatment data were collected on a patient who received intravenous hydroxypropyl beta-cyclodextrin in a dose of 1.5 g/kg in 1985. Although no untoward effects were observed in this patient, rarely occurring agitation and pulmonary edema have been noted after injections into rabbits and dogs, respectively. These complications are analyzed here on the basis of symptoms and on the effects of hydroxypropyl beta-cyclodextrin on the biochemistry of a representative lipid, cholesterol, which were studied in rats. It is hypothesized that these untoward effects of parenteral hydroxypropyl beta-cyclodextrin are due to complex formation, with lipid mediators of pathological responses, of which prostaglandins are one example. These mediators normally have brief and localized functions; if hydroxypropyl beta-cyclodextrin happens to be injected when these mediator systems are activated, their influence and the responses of the organism may be increased.

Although midazolam has been proposed for the treatment of a variety of conditions such as anxiety, dyspnoea, hiccups and status epilepticus, terminal agitation is the only condition where its use is based on a reasonably large number of published clinical studies. A causal approach is generally recommended. Whenever possible, the aetiological condition (pain, fever, constipation, etc.) should be corrected. Such general measures as ensuring a peaceful, familiar environment, and the use of a night light, fluid therapy to counteract dehydration, and antipyretics for fever are beneficial. When symptomatic treatment is needed, drugs with little anticholinergic effect are to be recommended. The use of benzodiazepines as single drug treatment may exacerbate the condition. Haloperidol or risperidone (which has fewer side effects) are recommended. If the agitation is marked, a common strategy is to add lorazepam. Chlormethiazole is an alternative. Subcutaneous midazolam should be reserved for refractory cases. Attention should be paid to dosage, reduced doses being given to the elderly, patients on opioid medication, and patients with impaired liver or renal function. Overdosage may induce deep sedation, and result in carbon dioxide retention and subsequently heart failure and pulmonary oedema which may be fatal.

Seventeen patients stung by Tityus serrulatus scorpion were classified as mild (pain at the site of the sting, n = 6), moderate (local pain and one of the following manifestations: vomiting, psychomotor agitation, prostration, sweating, tachypnea, tachycardia and mild arterial hypertension, n = 10) and severe cases (equal moderate cases plus cardiac failure, pulmonary edema and shock, n = 1). Venous blood was sampled for biochemical and hematological analysis and for IL-1alpha, IL-6, IL-10, TNF-alpha, IFN-gamma and GM-CSF ELISAs at the time of hospital admission, 6 h (moderate and severe cases), and 12, 18, 36 and 72 h (severe case) later. Ten age-matched healthy volunteers were used as control. Increased serum levels of IL-1alpha was noticed in all patients, high levels of IL-6, IFN-gamma and GM-CSF were observed only in a patient with severe envenomation. Our data suggest that a systemic inflammatory response-like syndrome is triggered during severe envenomation caused by T. serrulatus sting and that release of cytokines may be involved in this response.

Acute respiratory failure is a common complication of drug abuse. It is more likely to develop in the setting of chronic lung disease or debility in those with limited respiratory reserve. Drugs may acutely precipitate respiratory failure by compromising respiratory pump function and/or by causing pulmonary pathology. Polysubstance overdoses are common, and clinicians should anticipate complications related to multiple drugs. Impairment of respiratory pump function may develop from central nervous system (CNS) depression (suppression of the medulla oblongata, stroke or seizures) or respiratory muscle fatigue (increased respiratory workload, metabolic acidosis). Drug-related respiratory pathology may result from parenchymal (aspiration-related events, pulmonary edema, hemorrhage, pneumothorax, infectious and non-infectious pneumonitides), airway (bronchospasm and hemorrhage), or pulmonary vascular insults (endovascular infections, hemorrhage, and vasoconstrictive events). Alcohol, cocaine, amphetamines, opiates, and benzodiazepines are the most commonly abused drugs that may induce events leading to acute respiratory failure. While decontamination and aggressive supportive measures are indicated, specific therapies to correct seizures, metabolic acidosis, pneumothorax, infections, bronchospasm, and agitation should be considered. Drug-related respiratory failure when due to CNS depression alone may portend well, but in patients with drug-related significant pulmonary pathology, a protracted course of illness may be anticipated.
