Comparative StudyEffect of neuromuscular blockade on the elastic properties of the lungs, thorax, and total respiratory system in anesthetized pigs.
To evaluate the effect of neuromuscular blockade on the elastic properties of the lungs, thorax, and total respiratory system in pigs anesthetized to suppress spontaneous breathing. ⋯ Neuromuscular blockade does not alter the elastic properties of the lungs, chest wall, or total respiratory system in mechanically ventilated pigs receiving sodium pentobarbital anesthesia to suppress spontaneous breathing efforts.

Joint position statement: essential provisions for critical care in health system reform. Society of Critical Care Medicine. American Association of Critical Care Nurses.
Production of a statement defining the essential provisions of health system reform as determined by the Society of Critical Care Medicine (SCCM) and the American Association of Critical-Care Nurses (AACN). This document is the only nurse-physician joint statement to result from the 1994 health system reform debate. ⋯ SCCM and AACN agreed that health system reform should ultimately achieve universal coverage, access, control cost, and should improve the quality of care. SCCM and AACN endorsed improved access to and coverage for preventive care services. Recognizing that critical illness and injury cannot be prevented entirely, SCCM and AACN agreed that a reformed system must foster improved care of the critically ill and injured as described below.

Multicenter Study Comparative Study Clinical TrialMulticenter trial of a new thoracic electrical bioimpedance device for cardiac output estimation.
To evaluate the capacity of a new thoracic electric bioimpedance system to estimate cardiac output compared with the conventional thermodilution method. ⋯ The new bioimpedance system satisfactorily estimated cardiac output as measured by the thermodilution technique. The difference between the two estimations is more than made up for by the continuous noninvasive capability of the impedance system.

Randomized Controlled Trial Clinical TrialInfluence of pressure- and flow-triggered synchronous intermittent mandatory ventilation on inspiratory muscle work.
To determine the effect of pressure- and flow-triggered synchronous intermittent mandatory ventilation on inspiratory muscle work. ⋯ During synchronous intermittent mandatory ventilation, the method of ventilator triggering has a significant effect on the total work rate and inspiratory muscle work of the spontaneous breaths, particularly at lower machine support levels. Conversely, the method of ventilator triggering has no significant effect on inspiratory muscle work of the mandatory breaths.

Comparative StudyNeurologic outcome and heart resuscitability with closed-chest cardiopulmonary bypass after prolonged cardiac arrest times in rabbits.
To observe the influence of prolonged cardiac arrest times on neurologic outcome and heart resuscitability, using a resuscitation model with cardiopulmonary bypass in the rabbit, and to determine whether the changes in the plasma concentrations of lactate and lipoperoxide correlate with the severity of global brain ischemia. ⋯ Cardiopulmonary bypass can be used to establish a resuscitation model in rabbits. Neurologic outcome worsens progressively in proportion to the prolonged cardiac times, especially when it exceeds 10 mins. Cardiac resuscitability is still possible, even when arrest time exceeds 15 mins. Changes in plasma concentrations of lactate and lipoperoxide do not correlate with the neurologic outcome and heart resuscitability following cardiac arrest.
