手術患者の手術室入室より手術開始までの所要時間に関与する因子 ： 1992年麻酔科管理症例の検討

Abstract

The contributing factors which related to the duration of preoperative period in the operating theater of Nara Medical University Hospital are assessed. The 3295 anesthetic records from January 1 to December 31 of 1992 were examined retrospectively. The duration from arrival at the operating room to start of surgery were classified into five groups according to consumed time at intervals of 30 minutes. As the results, average duration was 47.8±22.2 min. In the elective cases, the most frequent subjects, 1889 patients (57%), were classified to 30-60 min group. They were composed of cases in the other departments except for Department of 2nd and 3rd Surgery which were classified to 30-60 min group and the cases of Department of 2nd and 3rd Surgery were classified to 60-90 min group. In the emergency cases, 181 patients (33%) were classified to less than 30 min group. As factors of time-consumption in the preoperative period (more than 90 min), we considered various procedures such as intubation using special endobronchial tube, puncture of central vein and artery, cannulation of Swan-Ganz catheter, epidural puncture, posture change etc. To reduce the duration of the preoperative period, we should reconsider the training curriculum of unexperienced anesthesiologists and keep the teamwork between anesthesiologists, surgeons, and nurses.
