Abstract 222: Risk Factors Analysis of Unresuscitated Patients With Intraoperative Cardiac Arrest
Background: Perioperative cardiac arrest remains a lethal complication of noncardiac surgery. Immediate survival after intraoperative cardiac arrest was around 50% according to reports. We sought to analysis risk factors of the patients who were not resuscitated after intraoperative cardiac arrest in our hospital. A retrospective case analysis study of all intraoperative cardiac arrest was done to determine the cause and outcome of cardiac arrest.
Methods: Medical records of noncardiac surgery patients who experienced cardiac arrest during the intraoperative period between January 1, 2005, and December 31, 2009 were reviewed. We defined cardiac arrest as an event that required resuscitation with either closed-chest compressions or open cardiac massage.
Results: Seventeen intraoperative cardiac arrest patients were reviewed during the study period (Table 1). Immediate survival after cardiac arrest was 53% in this study. Age, gender, weight and hemodynamic status before the surgery were no difference in patients who were resuscitated or not. The risk factors of unresuscitated patients include lower preoperative hemoglobin concentration (P<0.05), higher American Society of Anesthesiologists physical status (ASA PS, P<0.05). Survival was significantly higher in patients with ASA PS of I or II compared to those with ASA PS of III or higher. Preoperative blood glucose level and ST-T changes of Electrocardiogram (ECG) were no significant difference between resuscitated and unresuscitated patients (P>0.05). The methods of anesthesia have no effects on the survival between resuscitated and unresuscitated patients (P>0.05). The time of cardiac arrest occurrence since the induction of anesthesia had no difference between resuscitated and unresuscitated patients (P>0.05).
Conclusions: Lower preoperative hemoglobin concentration and higher ASA PS are risk factors of death for the patients with intraoperative cardiac arrest.
