Background
Adolescents and young adults are frequent users of alcohol. Younger patients may be more sensitive to the effects of alcohol than their adult counterparts, and toxicity has been known to occur at lower doses. Respiratory depression is a serious adverse effect of alcohol intoxication; however, current monitoring practices may not adequately detect respiratory depression.Objective
Our objective was to determine the frequency of hypoventilation as measured by capnography among adolescents with acute alcohol intoxication. Our secondary objective was to determine if an association exists between alcohol levels and incidence of hypoventilation.Methods
This was a prospective observational pilot study of patients 14–20 years of age with acute alcohol intoxication. Blood or breath alcohol measurements were obtained on arrival. Hourly measurements of vital signs including capnography were recorded.Results
Sixty-five subjects were analyzed. Mean alcohol level was 185 mg/dL. Twenty-eight percent of subjects had episodes of hypoventilation. Episodes occurred in similar proportions on arrival and during the first 5 h of measurements. There was no difference in alcohol levels between subjects who did and did not hypoventilate (185 mg/dL vs. 186 mg/dL; 95% confidence interval −29 to 25). Oxygen desaturations occurred in 14 subjects and were associated with hypoventilation (p = 0.015).Conclusions
Hypoventilation is common among adolescents who are acutely intoxicated with alcohol. It is independent of alcohol level and occurs at a steady rate during the first several hours of intoxication. Capnography should be considered as an additional monitoring device to detect these episodes and enhance patient safety. 相似文献4.

Objective: To determine lung compliance in patients who had out-of-hospital cardiac arrests.
Methods: A prospective, observational study of patients suffering nontraumatic cardiopulmonary arrest and requiring CPR at one university hospital ED. Following termination of resuscitation efforts, lung compliance was measured. Measurements were made while inflating the lung from 250 mL to 2.000 mL (in 250-mL increments) using a calibrated supersyringe. Airway flow and pressure were measured at the endotracheal tube with a pneumotachograph and a pressure transducer. Flow and pressure signals were recorded by a respiratory monitor and used to construct pressure-volume curves for calculation of lung compliance.
Results: The 25 cardiac arrest patients (17 men, eight women) had a mean (± SD) age of 65 ± 7 years. Mean lung compliance was 0.051 ± 0.011 L/cm H2 O. Lung compliance was smaller at low lung volumes, suggesting the presence of alveolar collapse. Compliance values from 500 mL to 1,500 mL were similar. Compliance also diminished with increasing duration of CPR.
Conclusions: One previous publication suggested that lung compliance following resuscitation is 0.022 L/cm H2 O. The results of this study, using the accepted standard measurements of static lung compliance, suggest that true compliance is twice this value. This finding has important ramifications for future research on ventilation during resuscitation and current ventilation standards. 相似文献

We report a case of severe hypokalemia and flaccid muscle paralysis following a suicide attempt associating the calcium channel blocker amlodipine, the antidepressant fluoxetine and barium carbonate. Despite rapid correction of severe, life-threatening hypokalemia, areflexic quadriplegia persisted, suggesting a direct effect of barium on muscle cells. Continuous veno-venous hemodiafiltration (CVVHDF) was initiated. We determined barium concentration in the urine, plasma, and hemodiafiltrate during CVVHDF. We subsequently calculated the amounts of barium eliminated both by the CVVHDF and the kidneys. CVVHDF triples the measured barium elimination, reduced serum barium half-life by a factor of three, stabilized serum potassium levels, and rapidly improved motor strength, with complete neurological recovery within 24 h. Presentation and treatment of barium intoxication are discussed. 相似文献

A 20 year old male naval crew-member suffering from sea sickness was treated with transdermal scopolamine (TS). After 5 months of continuous treatment, he developed scopolamine intoxication followed by the appearance of recurrent classic migraine attacks. He had never suffered from headache or migraine prior to TS intoxication. The migraine attacks comprised a prodrome of apathy, bad mood and loss of appetite lasting several hours. An aura of scintillating spots, left arm numbness and paresthesias lasting several minutes was followed by a severe throbbing unilateral headache with photophobia, sonophobia and nausea. After one year of repeated follow-up examination, he continued to suffer from the attacks once every 10 to 14 days, with no identified precipitating factors. We are not aware of similar cases in the medical literature. Although it is not possible to establish TS intoxication as a causal effect of the appearance of classic migraine in our patient, the temporal association and clinical course are very supportive of this assumption. Central nervous system neurotransmitter imbalance of cardiovascular alterations may possibly be implicated. 相似文献

Background: Salicylate poisoning is a common problem with appreciable morbidity and mortality. We present a case of a patient with a large aspirin ingestion who expired despite aggressive hemodialysis (HD). Case Report: A 35-year-old man arrived at the Emergency Department 7.5 h after ingesting 400 tablets of 325-mg aspirin. He was afebrile, the respiratory rate (RR) was 30 breaths/min, heart rate (HR) 120 beats/min, blood pressure (BP) 125/76 mm Hg, and oxygen saturation 99% on room air. His salicylate concentration was 89.6 mg/dL. His initial arterial blood gas: pH 7.48, pCO2 21 mm Hg, PaO2 97 mm Hg, and bicarbonate 15.8 mmol/L. His initial serum chemistry panel was normal. He received activated charcoal and intravenous hydration with sodium bicarbonate. Two hours after arrival, salicylate concentration was 91.6 mg/dL. The patient became agitated and HD was initiated; 22 h after presentation, repeat salicylate concentration was 88.4 mg/dL and his creatinine was 3.9 mg/dL. A second run of HD was performed. After this, his temperature had risen to 39.06°C (102.3°F), BP 122/64 mm Hg, HR 168 beats/min, RR 43 breaths/min, and oxygen saturation 95% (2 L nasal cannula). His confusion increased, and he died 40 h after his ingestion. Conclusion: HD is widely advocated in managing severe salicylate intoxications, however, no consensus exists for the duration and best mode of therapy. Patients with severe salicylate poisonings may require extended durations of HD to effectively mitigate toxicity. Additional study is warranted to determine optimal therapy in severe salicylate intoxications. 相似文献

WILLAERT, W., et al. : Intoxication with Taxus Baccata: Cardiac Arrhythmias Following Yew Leaves In-gestion. The use of yew leaves (Taxus Baccata) as a means of deliberate self-harm is infrequent. The potent effect of the toxin is primarily cardiac and results in rhythm alterations and ultimately ventricular fibrillation. As there is no known antidote, and classic antiarrhythmic therapy proves to be ineffective, a prompt diagnosis is of great importance as immediate supportive action is the only valuable alternative. This case describes a 43-year-old women who attempted suicide by ingesting the leaves of Taxus Baccata. We discuss the effects and the difficulty of treatment associated with yew leaf poisoning. 相似文献
