ASA: American Society of Anaesthesiologists. NA: not applicable. WBC: white blood count. SIRS: systemic inflammatory response syndrome. #Shock defined as systolic blood pressure of less than 100 mmHg or heart rate of more than 100 beats per minute. SIRS defined as 2 or more of the following variables: (1) fever of more than 38°C (100.4°F) or less than 36°C (96.8°F); (2) heart rate of more than 90 beats per minute; (3) respiratory rate of more than 20 breaths per minute or arterial carbon dioxide tension (PaCO2) of less than 32 mmHg; (4) abnormal white blood cell count (>12,000/µL or <4,000/µL or >10% immature forms).
