Preoperative testing.

摘要

Three recent articles and an editorial in this journal have discussed the value of preoperative testing. Joo et al. concluded that, in agreement with current Canadian guidelines, routine preoperative chest x-rays should not be performed without risk factors. Finegan et al. demonstrated that selective test ordering by staff anesthesiologists reduced the number and cost of preoperative investigations. Finally, Yuan et al. documented marked disparities in the practice of preoperative testing by members of the Canadian Anesthesiologists, Society of patients undergoing ambulatory surgery.
