Randomized Controlled Trial Clinical TrialFrequency of mortality and myocardial infarction during maximizing oxygen delivery: a prospective, randomized trial.
To determine the frequency of myocardial infarction and mortality during treatment that increased oxygen delivery (DO2) to > or = 600 mL/min/m2. To define the characteristics of patients achieving a high DO2 without inotropes in order to guide future studies. ⋯ The group that required catecholamines to achieve a DO2 of > or = 600 mL/min/m2 had a lower mortality rate, with no increase in the frequency of myocardial infarction. Future prospective, controlled trials examining select groups of patients (age > or = 50 yrs) may demonstrate a difference between control and treatment groups by eliminating the majority of patients who generate the high DO2 with only preload augmentation.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of different intermittent mandatory ventilation rates on oxygen consumption in premature infants recovering from respiratory distress syndrome.
Oxygen consumption at intermittent mandatory ventilation (IMV) rates of 10 and 20 breaths per minute was evaluated to determine whether a higher IMV rate in mechanically ventilated premature infants with apnea and respiratory insufficiency would reduce metabolic expenditure. Ten studies were performed in seven infants, with three infants studied twice after a trial of failed elective extubation. The mean birth weight was 952 +/- 183 kg (SD), and the mean postnatal age was 12 +/- 8 days (SD). ⋯ The oxygen consumption difference at the two IMV rates was not significantly related to dynamic lung compliance, resistance, or work of breathing. These results demonstrate that mechanically dependent premature infants without bronchopulmonary dysplasia do not have significant alteration in oxygen consumption with changes in IMV. This finding suggests that there is no potential metabolic energy balance benefit in use of moderately higher IMV rates to achieve improved growth rates in this population of infants.

Hypocarbia before surfactant therapy appears to increase bronchopulmonary dysplasia risk in infants with respiratory distress syndrome.
To determine to what extent the risk of bronchopulmonary dysplasia is affected by ventilatory management before the first dose of rescue artificial surfactant. ⋯ Ventilatory management before rescue treatment with artificial surfactant therapy that result in hypocarbia may increase the risk of bronchopulmonary dysplasia. These findings suggest that early ventilatory management should not only provide adequate oxygenation but also limit hyperventilation.

Review Case Reports
A case report of disseminated blastomycosis and adult respiratory distress syndrome.
Blastomycosis is a fungal disease endemic to the midwestern and southeastern United States. This is a case report of a 29-year-old woman who presented with weight loss, fever, fatigue, and pneumonia. ⋯ Blastomycosis is endemic to a large portion of the United States. Family physicians should consider fungal infection in the differential diagnosis of an unresolving pneumonia.

To characterize the physiologic response to, and safety of, intravenacaval membrane oxygenation and carbon dioxide removal. ⋯ Intravenacaval membrane oxygen and carbon dioxide removal can provide partial respiratory support during severe respiratory failure and permit reductions in the level of mechanical ventilator support, with an acceptable safety profile.
