摘要:

We studied the effects of no treatment, furosemide treatment, and isolated ultrafiltration on extravascular lung water (ETV1.) in mongrel dogs in whom pulmonary edema was induced with oleic acid. In all treatment groups, ETV1. was significantly elevated 90 min after oleic acid infusion. At 270 min, we found no difference between nontreatment and furosemide. There was, however, a significant difference between no treatment and ultrafiltration but not between furosemide and ultrafiltration. In spite of observations which suggest that ultrafiltration is of benefit in reducing ETVL, we could not demonstrate superiority of one therapy over another.

摘要:

Much attention has been directed to developing early therapy that might prevent or ameliorate incipient adult respiratory distress syndrome (ARDS) before respiratory failure ensues. The relationship between increased extravascular lung water (EVLW) and pulmonary microvascular pressure has been used by numerous investigators to confirm alterations in the permeability of the alveolar capillary membrane. In the present study, EVLW was measured in 40 critically ill patients by an indicator dilution technique utilizing thermal indicator alone. Injection of cold saline distinguished intravascular and extravascular compartments with a sensitivity similar to that of the thermal-dye double-indicator dilution technique but without the withdrawal of blood, dye densitometry, or the preparation of special injectate. Both absolute volumes and volume changes over time measured by the single thermal indicator method compared favorably (p< .001) to EVLW values determined simultaneously by the conventional thermal-dye double-indicator dilution technique. These results suggest that the single thermal indicator technique may help identify the earliest phase of ARDS when fluid is starting to accumulate in the lung interstitium.

摘要:

The accuracy and reproducibility of thermodilution cardiac output measurements were examined in vitro at low flows, using the Edwards cardiac output computer. For each of 18 different volumetrically measured flows between 130 and 1035 ml/min, three cardiac outputs were determined for each of four different injectate volumes (1,2,3, and 5 ml) at two different temperatures (0°C and room temperature). There was a significant (p< .001) correlation between measured flow and cardiac output for all injectate volumes at both temperatures. The slopes of the regression lines ranged between 0.97 and 1.25, and the y-intercepts were all greater than 0. Although this thermodilution technique overestimated cardiac output, it was a reproducible means of measuring cardiac output in this low-flow in vitro model.

摘要:

A computer program is presented which analyzes acid-base and respiratory variables. This program's advantages include limited data input, hand-held portability, error identification, and succinct analysis statements. It is a useful adjunct to daily care of the critically ill.

摘要:

Parenteral hyperalimentation is an important means of nutritional support for critically ill patients. Calculating the amount of additives necessary for the appropriate compounding of hyperalimentations is a tedious process with many opportunitities for error. A new computer program written in Pascal has been created to reduce pharmacy processing time. Menus and singlekeystroke entry are implemented wherever practicable. A hard-copy printout and an individualized label are generated on command. Program testing has resulted in an 88% reduction of processing time.

摘要:

A patient who received an erroneous transfusion of outdated and partly homogenized blood is reported. Although marked hemoglobinemia was present, only transient hemodynamic, pulmonary, and renal alterations were observed. Massive embolism of microaggregates and norepinephrine release might explain our findings. Dopamine (3 μg/kg min) might have beneficial effects on renal function in this pseudohemolytic transfusion reaction.

摘要:

Intubation of a 23-month-old child suffering epiglottitis was complicated by pulmonary edema progressing to the adult respiratory distress syndrome. Increased pulmonary shunt and pulmonary hypertension required high levels of positive end-expiratory pressure and prolonged mechanical ventilation to correct hypoxemia. A possible role for a cuffed endotracheal tube in epiglottitis is discussed.
