Early recognition and administration of the specific antidote methylene blue may lead to complete recovery. A 39-year-old man ingested 100 ml of a liquid he believed to be beer. On arrival in our department he was deeply cyanosed and unconcious with a pulse of 140 and a blood pressure of 70 systolic. Endotracheal intubation and ventilation with 100% oxygen failed to improve the cyanosis and a clinical diagnosis of methaemoglobinaemia was made. Despite intravenous methylene blue he developed an asystolic cardiac arrest from which he could not be resuscitated. Subsequent analysis of the ingested fluid showed it to contain 33.5% sodium nitrite. Sodium nitrite is used in industry during the manufacture of dyes and synthetics and is also used in low concentrations as a meat preservative. There are reports of nitrite poisoning due to' its excessive use a meat preservative (Walley et al., 1987) or as a result of mistaking sodium nitrite for table salt (McQuiston 1936). Abuse of organic nitrites by ingestion or inhalation for their psychodelic and stimulant properties may also lead to methaemoglobinaemia (Shesser et al., 1981). Small doses of sodium nitrite may produce headache, vomiting, diarrhoea, flushing and cyanosis. Ingestion of more than 1 g of sodium nitrite leads to rapid cardiovascular collapse and death (Polson et al., 1969). Typically, samples of the patients blood are dark brown and confirmation of the diagnosis is obtained by measuring serum methaemoglobin levels. Treatment of nitrite poisoning consists of the administration of high concentrations of oxygen and methylene blue intravenously in a dose of 1-2mgkg-1 body weight. Methylene blue acts by promoting reduction of the oxidized haem iron back to its ferrous state (Polson et al., 1969). Nitrite poisoning and methaemoglobinaemia are rare, however awareness of this condition in the cyanosed patient unresponsive to oxygenation and early administration of methylene blue may be life saving. It is recommended that methylene blue is available in Accident and Emergency A&E units for use in such cases.","PeriodicalId":77009,"journal":{"name":"Archives of emergency medicine","volume":"10 3","pages":"260-1"},"PeriodicalIF":0.0,"publicationDate":"1993-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/emj.10.3.260","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19206097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A prospective case comparison trial was used. The study was carried out at two university affiliated community hospitals, one in the U.S.A and one in England. Subjects were consecutive patients triaged as requiring critical care services and subsequently admitted to the hospital ward (A, n = 17; E, n = 18) or the intensive/critical care unit ([ICU] A, n = 14; E, n = 24). The study time period was randomly selected 8-h shifts occurring over a 4-week period. All patients were treated by standard guidelines for critical care services at the study hospital emergency department. For all study patients mean length of stay was significantly longer for the American (233 min, 95% CI 201, 264) than the English ED (24 min, 95% CI 23, 25). American emergency physicians spent less total time providing physician services (19.2 min, 95% CI 16.8, 21.6) vs. (23 min, 95% CI 21.6, 24.4) than English emergency physicians. American emergency physicians spent less time with the patient than English emergency physicians: 12.4 min (95% CI 10.3, 14.5) vs. 17 min (95% CI 15.8, 18.2). American emergency physicians spent more time on the telephone 1.8 min (95% CI 1.4, 2.2) vs. 1.2 min (95% CI 1.1, 1.3), and in patient care discussions/order giving 1.8 min (95% CI 1.4, 2.2) vs. 1.1 min (95% CI .8, 1.4), There was no significant difference in time charting (3.2 min, 95% CI 2.8, 3.6 vs. 3.5 min, 95% CI 3.2, 3.8). Results did not vary significantly whether analysed subgroups or the whole study group. American emergency physicians provided 81% of their service during the first hour. There were delays at the American hospital until the physician saw the patient: 4.9 min (95% CI 2.5, 7.3) for patients admitted to the ICU/CVU (Cardiovascular Unit), and 9.2 min (95% CI 4.6, 13.8) for patients admitted to the ward. At the American hospital, ICU/CVU physicians provided additional physician services in the emergency department whether the patient was admitted to the ward (6.7 min, 95% CI 5.5, 7.9) or the ICU/CVU (12.1 min, 95% CI 8.8, 15.9). For patients admitted to the ICU/CVU 47% of the length of stay was spent waiting for a bed to become available after the decision to admit had been made. Emergency physicians at E provided critical care services almost continuously during a short stay in the ED. Emergency physicians at A provided services intermittently with most services during an initial period of stabilization. Further study is necessary to identify what factors contribute to these different approaches to critical care in the ED.</p>","PeriodicalId":77009,"journal":{"name":"Archives of emergency medicine","volume":"10 3","pages":"145-54"},"PeriodicalIF":0.0,"publicationDate":"1993-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/emj.10.3.145","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19206248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
