[Comparative evaluation of methods of determining surgical risk in relation to age]
Abstract:
The authors have developed a method for the assessment of the degree of the operation risk with special reference to the clinical (nosological) age showing the functional state of the main vital systems of the organism, the degree of the main and accompanying diseases, the character and volume of the surgery. The frequency of postoperative complications and the lethality rate depending on different degrees of the operation risk were studied on the basis of 1922 case histories of surgical patients. Certain different classifications of the operation risk are compared. The authors propose a classification of the degree of the risk of surgical diseases to be compared with the operation risk.
