Refibrillation managed by EMT-Ds: incidence and outcome without paramedic back-up.

JOURNAL ARTICLE.

Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not (53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available.

Tricyclic antidepressant overdose: emergency department findings as predictors of clinical course.

JOURNAL ARTICLE.

There is controversy regarding the appropriate utilization of health care resources in the management of tricyclic antidepressant overdosage. Antidepressant overdose patients presenting to the emergency department (ED) are routinely admitted to intensive care units, but only a small proportion develop cardiac arrhythmias or other complications requiring such an environment. The authors reviewed the findings in 165 patients presenting to an ED with antidepressant overdose. They found that major manifestations of toxicity on ED evaluation (altered mental status, seizures, arrhythmias, and conduction defects) were commonly associated with a complicated hospital course. Patients with the isolated findings of sinus tachycardia or QTc prolongation had no complications. No patient experienced a serious toxic event without major evidence of toxicity on ED evaluation and continued evidence of toxicity during the hospital course. These data support the concept that proper ED evaluation can identify a large body of patients with trivial ingestions who may not require hospital observation.

Transconjunctival oxygen monitoring as a predictor of hypoxemia during helicopter transport.

JOURNAL ARTICLE.

As the use of helicopters for air transport of critically ill patients increases, the availability of monitoring devices for physiological parameters during flight becomes important. It has long been known that arterial PO2 (PaO2) decreases during unsupplemented, non-pressurized flight. In this study, the authors examined the use of the transconjunctival oxygen (cjO2) monitor for assessing the adequacy of arterial oxygenation during helicopter flight in four healthy volunteers. Arterial PaO2 as measured by conventional blood gas analysis was compared with cjO2 at ground level, 5,000 feet, and 10,000 feet altitude. Mean PaO2 dropped significantly from 93.5 to 81.5 to 58.5 mm Hg, respectively (P less than 0.001, analysis of variance with repeated measures). Mean cjO2 also decreased significantly from 63.8 to 52.0 to 34.8 mm Hg, respectively (P less than 0.001, analysis of variance with repeated measures). Within individual subjects, cjO2 was an accurate predictor of PaO2 (P less than 0.001, multiple regression analysis). The relationship between cjO2 and PaO2 was linear with a regression coefficient of 1.147. The authors conclude that the transconjunctival O2 monitor may be useful for monitoring the adequacy of arterial oxygenation during helicopter flight in hemodynamically stable patients. The results of study also support the use of supplemental oxygen in all patients subjected to helicopter transport.

Serum glucose changes after administration of 50% dextrose solution: pre- and in-hospital calculations.

JOURNAL ARTICLE.

A prospective clinical trial was conducted to estimate the rise in serum glucose level after an intravenous bolus of 50 ml of 50% dextrose solution (D-50) in the emergency department setting. Fifty one subjects with altered levels of consciousness were studied. Of these, 23 patients were known diabetics, and 28 were not diabetic. The change in glucose level for the total study group ranged from a low of 37 mg/dl to a high of 370 mg/dl, with a mean of 166 +/- 77 mg/dl. The mean for the diabetic and non-diabetic groups were 177 +/- 80 mg/dl and 154 +/- 75 mg/dl. These results suggest that serum glucose levels cannot be quantitatively predicted after a single intravenous bolus of D-50.

Nasogastric intubation: morbidity in an asymptomatic patient.

JOURNAL ARTICLE.

An unusual case of a misdirected nasogastric tube is described. An elderly woman was brought to an emergency department following intentional drug overdose. Initially unrecognized errant placement of a large-bore nasogastric tube resulted in tension pneumothorax, pneumonia, and subsequent death. Pertinent medical literature is reviewed, clinical considerations for the elderly patient are discussed, and suggestions for proper nasogastric tube placement are offered.

JOURNAL ARTICLE.

In the critically ill child, administration of fluids and medications via the intraosseous route often proves life-saving. The authors describe the case of a child with status epilepticus in whom phenytoin was administered via the intraosseous route, and seizure resolution and therapeutic serum levels were achieved. Intraosseous drug administration should be reserved for the rare critically ill child in whom vascular access proves impossible.

Boerhaave's syndrome: an elusive diagnosis.

JOURNAL ARTICLE.

Boerhaave's syndrome represents a diagnostic dilemma for the emergency physician. The prognosis of this truly life-threatening emergency is darkened by any significant diagnostic delay. Unfortunately, classic or expected symptoms and signs are frequently absent at presentation, a circumstance that leads to frequent misdiagnosis. Two cases of Boerhaave's syndrome with "atypical" clinical presentations are reviewed and discussed. It is clear that Boerhaave's syndrome should always be suspected in the evaluation of any sudden chest, abdominal, or back pain associated with emesis. However, emphasis should be placed on the fact that this entity may occur without emesis. The chest radiograph is the most helpful diagnostic aid. Undoubtedly, maintenance of a high degree of suspicion by the emergency physician for Boerhaave's syndrome will lead consistently to earlier diagnosis, and subsequent aggressive intervention should result in considerable reduction in rates of both morbidity and mortality.

Intraosseous infusions: a usable technique.

JOURNAL ARTICLE.

Intraosseous infusions were widely used in pediatric patients during the 1930s and 1940s. Recent reports have re-introduced this concept and confirmed its safety and ready accessability for fluid and drug administration. However, these reports have not addressed the difficulties encountered during insertion of the intraosseous needle. Spinal needles, standard metal intravenous (IV) needles, and bone marrow biopsy needles have been suggested for intraosseous infusion. These needles were tested for ease of insertion on a pediatric cadaver leg. The site for needle placement was also evaluated during the study. It was found that the 13-gauge Kormed/Jamshidi disposable bone marrow/aspiration needle was the easiest to insert and did not plug with bone or tissue during insertion. An area proximal to the medial malleolus was found to provide a stable, relatively flat, and easily penetrable location for needle placement. This method was successfully utilized in ten pediatric and five adult patients. Intraosseous needle placement is a safe, rapid method to gain access to the venous circulation. By utilizing these techniques, a stable, usable fluid line can be established in even the most dehydrated pediatric patients.

JOURNAL ARTICLE.

The case of a man who injected turpentine intravenously in an attempt to kill himself is reported. The patient developed immediate pulmonary edema and hypoxia, followed later by cellulitis at the site of injection. Although only one death to date has been attributed to this form of chemical abuse, extensive local reactions, pulmonary involvement, central nervous system depression, and febrile reactions should be anticipated, and such patients should be admitted to the hospital. Patients should be observed for local reactions and myonecrosis around the site of injection, especially as these occur 12-24 hours later.

Pulmonary edema induced by intravenous ethchlorvynol.

JOURNAL ARTICLE.

The intravenous injection of ethchlorvynol is an uncommon cause of noncardiac pulmonary edema. Two cases of intravenous ethchlorvynol-induced pulmonary edema are presented. The patients fell asleep after injecting the liquid contents of Placydil capsules (ethchlorvynol) and awoke several hours later with severe dyspnea. Arterial blood gases demonstrated marked hypoxia. Chest radiographs revealed bilateral diffuse alveolar densities. The patients' symptoms and radiographic findings resolved after several days of supportive care. Changes in the lung caused by ethchlorvynol may be the result of direct effect of the drug on the lung.

Atropine in the treatment of baclofen overdose.

JOURNAL ARTICLE.

A patient suffering baclofen overdose successfully treated with atropine is reported. Three hours after admission for ingestion of at least 300 mg baclofen as a single dose, the patient became comatose and subsequently bradycardic, hypotensive, and hypothermic. A prompt increase in heart rate and blood pressure followed administration of 1 mg of atropine sulfate. Atropine appears to be useful in treating cases of baclofen overdose complicated by bradycardia and hypotension.

Laser welding of large diameter arteries and veins.

JOURNAL ARTICLE.

Based on our preliminary studies and the results of this study, we conclude that argon laser welding of 4-8 mm internal diameter veins, arteries, and arteriovenous fistulas may have several potential advantages compared to conventional suture techniques. The benefits of laser repairs may include improved mechanical properties, and absence of the foreign body response related to sutures. Laser welding is sterile, nontactile and possibly time conserving, and the wounds heal rapidly without aneurysms or excess tissue proliferation.

JOURNAL ARTICLE.

The System 7 pump/actuator/engine combination has demonstrated biologic compatibility and physiologic effectiveness and responsiveness in five TVAS in vivo studies. The recent 75-day implant supports the feasibility of extended reliability of the system components. Postoperative system maintenance was necessary only because of the nonhermetic design of System 7. However, the ability to pump 11 l/min at 120 beats/min, synchronize at beat rates of 144 beats/min, and pump against mean arterial pressures of more than 150 mmHg while maintaining hematologic and biochemical values within physiologic range sets a very optimistic stage for System 8 hardware. A System 8 concept is shown in Figure 14. The System 8 hardware will include a thermal salt package capable of providing completely untethered circulatory support for a nominal 8-h period. Recharge will be accomplished with a transcutaneous transformer in 1 h. Thermal management problems become minimal, with an average energy input of 15.8 W (peak of 24.9 W). The human preclinical testing of System 8 will start in 1988.

However, the ability to pump 11 l/min at 120 beats/min, synchronize at beat rates of 144 beats/min, and pump against mean arterial pressures of more than 150 mmHg while maintaining hematologic and biochemical values within physiologic range sets a very optimistic stage for System 8 hardware. A System 8 concept is shown in Figure 14. The System 8 hardware will include a thermal salt package capable of providing completely untethered circulatory support for a nominal 8-h period. Recharge will be accomplished with a transcutaneous transformer in 1 h. Thermal management problems become minimal, with an average energy input of 15.8 W (peak of 24.9 W). The human preclinical testing of System 8 will start in 1988.

The motor drive has functioned for periods up to 93 days in vivo with no measurable wear. The compliance chamber volume varies by 100 cc during VAD function but does so while maintaining pressure variations below 15 mmHg. Compliance chamber volume loss of 2 to 5 cc/day is explained by gas transport through SPU. The subcutaneous sampling port provides ready access to the sealed system.

Compliance chamber volume loss of 2 to 5 cc/day is explained by gas transport through SPU. The subcutaneous sampling port provides ready access to the sealed system.

Removal of aluminum from chronic dialysis patients by administration of desferrioxamine and dialysis.

JOURNAL ARTICLE.

In order to perform quantitative in vitro and clinical studies on the removal of Al by the combined therapy of DFO administration and HD, an HPLC system for measuring DFO was established and a leaky membrane with enhanced permeability to middle molecular substances was developed. The DFO infusion caused rises in plasma Al levels (regarded as indicating the elution of accumulated Al) in patients undergoing HD. Plasma levels increased most in long-term patients and those with bone pain. Examination of Al clearances demonstrated that this increased plasma Al content passed through HD membranes at levels of more than 80 micrograms/l, and that the leaky membrane was more effective for removal of Al as well as DFO than the conventional one. Although a 1:1 complex between DFO and Al in an aqueous solution was confirmed, the formation of Al-rich complexes in vivo was suggested. It is concluded that Al-DFO complex formed in vivo can be effectively removed across the leaky membrane.
