Arterial-venous carbon dioxide tension difference during severe hemorrhage and resuscitation.
To define clinically useful markers for determining the adequacy of resuscitation after hemorrhage. ⋯ These findings suggest that the adequacy of resuscitation after hemorrhage can be assessed using paired arterial and mixed venous pH and PCO2 values.

Clinical TrialIntestinal platelet trapping after traumatic and septic shock. An early sign of sepsis and multiorgan failure in critically ill patients?
Patients resuscitated after severe traumatic or septic shock were studied with reference to the behavior of radiolabeled platelets in vital organs, the occurrence of sepsis, and multiorgan failure. These findings were compared with findings of patients who had sustained severe head trauma, but had reportedly not been in shock. ⋯ The results indicate that, in patients resuscitated after severe traumatic or septic shock, increased sequestration of platelets in the intestine, as measured by external detection of radioisotope-labeled autologous platelets, may precede clinical signs of sepsis and multiorgan failure and may possibly predict the outcome.

Generation of anaphylatoxin C3a in plasma and bronchoalveolar lavage fluid in trauma patients at risk for the adult respiratory distress syndrome.
To determine the generation of anaphylatoxin C3a in plasma and bronchoalveolar lavage fluid in trauma patients at risk for the adult respiratory distress syndrome (ARDS). ⋯ The C3a of epithelial lining fluid to plasma ratio was extremely high in patients developing ARDS, but even the non-ARDS group had a ratio greater than 1, indicating that a substantial local complement activation occurs in the lung.

Influence of age on outcome of mechanically ventilated patients in an intensive care unit.
To assess the influence of age on the outcome of patients receiving prolonged mechanical ventilation. ⋯ An influence of age on the outcome of mechanically ventilated patients in the ICU could not be ascertained in this study.

Site of pressure measurement during spontaneous breathing with continuous positive airway pressure: effect on calculating imposed work of breathing.
To describe the importance of measuring pressure at the tracheal end of the endotracheal tube during spontaneous breathing with continuous positive airway pressure in order to correctly assess: a) the changes in airway pressure and b) the work imposed by the breathing apparatus. ⋯ The results indicate that pressure should be measured as close to the patient's airway as possible, i.e., at the tracheal end of the endotracheal tube, rather than using the traditional approach of measuring pressure and assessing work at the inspiratory or expiratory limbs, or "Y" piece of the breathing tubing.
