Many perioperative managers record operating room times (ORTs) and use average ORTs to facilitate scheduling of elective surgical procedures. A second statistic, the upper 95% prediction level (ie, 95% chance the next ORT will be less than the upper prediction level) can be calculated from previous ORTs and used in scheduling elective procedures. ⋯ Upper prediction levels can provide perioperative managers better knowledge than average ORTs to facilitate decision making during the scheduling of elective surgical procedures. This method can be used to find upper prediction levels for any desired measure of procedure duration (eg, surgeon, scheduled procedure-specific times).

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of continuously warmed i.v. fluids on intraoperative hypothermia.
The investigators examined the effect of infusing continuously warmed (ie, 37.0 degrees C [98.6 degrees F]) i.v. fluids in two groups of middle-aged female patients undergoing laparoscopic cholecystectomy procedures. They hypothesized that increasing i.v. fluid temperature during surgery would decrease patients' risk for hypothermia. ⋯ Analyses of covariance, with the first intraoperative temperature measurement treated as the covariate, revealed nonsignificant results at the P < .05 level. The results suggest that administering continuously warmed i.v. fluids intraoperatively has no significant effect on maintaining patients' body temperatures during short laparoscopic surgical procedures.
