Ziser et al identified risk factors associated with perioperative complications and long term mortality in patients with cirrhosis who underwent surgery. Most of the risk factors can be identified prior to surgery. The authors are from the Mayo Clinic.
Parameters:
(1) gender
(2) Child-Pugh score

(4) cause of cirrhosis
(5) serum creatinine level
(6) chronic obstructive pulmonary disease (COPD)
(7) preoperative infection
(8) preoperative upper GI bleeding
(9) ASA physical status rating
(10) degree of surgical severity
(11) surgery on the respiratory system
(12) intraoperative hypotension
