Perioperative Mortality and Risk Factors in Nakornping Hospital - ปัจจัยเสี่ยงและอุบัติการการเสียชีวิตระหว่างและหลังการให้ยาระงับความรู้สึกในโรงพยาบาลนครพิงค์

Abstract

             The overall perioperative mortality of previous studies were reported to be 18.9-28.3 per 10,000 cases. The investigation related to the quality of anesthetic services at Nakornping hospital was aimed at defining the incidence of perioperative mortality and risk factors. This analytical study reviewed retrospectively medical records of 14,676 anesthetic cases in Nakornping hospital from October 2006 to September 2007. Records on all patients who died intraoperatively or within 24 hours after anesthesia were explored focusing on the related causes and, then, classified to determine relationship with anesthesia. Patient’s data were analyzed by univariate and multivariate analysis to identify the risk factors. The incidence of 24 hrs. perioperative death was 14.3 per 10,000 anesthetics. Of the 21 deaths, patient disease- related and surgical- related were 57.1 percent and 42.8 percent respectively. The common main causes of death were hypovolemic shock (47.6%) and septic shock (38.0%). Anesthetic- related death was not found. Risk factors included ASA class and anesthetic technique. This study showed 24 hrs. perioperative death was lower than those reported by previous studies. No anesthetic -related death was found. These preliminary findings suggest that further investigation will be useful in the study of anesthesia directly or partially related death and the development of preventive strategies.

Key words: risk factors, perioperative mortality, anesthesia
