Noninvasive monitoring of end-tidal CO2 via nasal cannulas in spontaneously breathing children during the perioperative period.
To determine the correlation between end-tidal CO2 and PaCO2 values measured via nasal cannulas in spontaneously breathing children during the perioperative period. ⋯ End-tidal CO2 measurement by infrared spectroscopy provided an accurate estimation of PaCO2 in this patient population. Its use may limit the need for invasive monitoring and/or repeated arterial blood gas analysis.

Mechanisms of change in cardiac performance in infants undergoing extracorporeal membrane oxygenation.
To determine whether changes in cardiac performance observed in infants early during extracorporeal membrane oxygenation are due to the underlying disease process, the partial bypass procedure, changes in cardiac loading conditions, or due to a direct myocardial effect of hypoxia-reoxygenation. ⋯ The previously described decreases in cardiac performance during extracorporeal membrane oxygenation are not due to the underlying disease process or the bypass procedure but are due to changes in loading conditions during partial bypass.

Assessment of critical care nurses' knowledge of the pulmonary artery catheter. The Pulmonary Artery Catheter Study Group.
To assess the knowledge and understanding of the use of the pulmonary artery catheter and interpretation of data derived from it in a group of nurses attending the American Association of Critical Care Nurses' National Teaching Institute conference. ⋯ A wide variation in the understanding of the use of the pulmonary artery catheter exists among nurses using this device in the care of seriously ill patients. The results indicate that current teaching practices regarding the pulmonary artery catheter need to be reevaluated and specific credentialing policies need to be considered.

Randomized Controlled Trial Comparative Study Clinical TrialRacemic versus l-epinephrine aerosol in the treatment of postextubation laryngeal edema: results from a prospective, randomized, double-blind study.
To determine whether any advantage exists using racemic epinephrine instead of the more potent and less expensive levo(1)-epinephrine in the treatment of postextubation laryngeal edema. ⋯ These data suggest that aerosolized l-epinephrine is as effective as aerosolized racemic epinephrine in the treatment of postextubation laryngeal edema without additional adverse side effects. When dosed appropriately, l-epinephrine is a less expensive and more widely available alternative to racemic epinephrine for the treatment of postextubation laryngeal edema.
