To test or validate a previously reported model for predicting postoperative pulmonary complications (PPCs) after elective abdominal surgical procedures. ⋯ Further research is needed to assess the stability of the risk factors and test the models in differing settings and populations of patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Effectiveness of a music therapy intervention on relaxation and anxiety for patients receiving ventilatory assistance.
To test the effects of music therapy on relaxation and anxiety reduction for patients receiving ventilatory assistance. ⋯ A single music therapy session was found to be effective for decreasing anxiety and promoting relaxation, as indicated by decreases in heart rate and respiratory rate over the intervention period with this sample of patients receiving ventilatory assistance.

Randomized Controlled Trial Clinical Trial
A comparison of intravascular pressure monitoring system contamination and patient bacteremia with use of 48- and 72-hour system change intervals.
To determine the incidence of culture positivity in intravascular monitoring systems by comparing 48- versus 72-hour intervals for flush solution, stopcocks, and catheters on removal. ⋯ Our results showed that increasing the change interval to 72 hours did not increase the risk of catheter-associated infection or catheter-associated bacteremia. Chi-square analysis did not show an association between culture-positive stopcocks, the incidence of culture-positive catheter tips, entries into the system, or catheter-related bacteremia and a change interval that was increased to 72 hours. Thus, increasing the change interval to 72 hours does not increase the risk of infection.
