[Complications of anesthesia in elderly patients]

Progress in surgery and anesthesia has contributed to lowering operative risk and expanding the indications for operations in higher age groups. The goal of treatment in the elderly is to achieve the best possible degree of reducing discomfort and increasing personal independence. Methods. A brochure with a clinical study on 1,021 patients chosen at random shows the frequency of complications arising during the peri- and post-operative course in patients around 60 years of age and older. Operative areas were general and emergency surgery, vascular surgery, neurosurgery, and urology. Operations were carried out in regional or general anesthesia. Patients were divided into groups below and above age 60. Evaluation of the data was carried out according to an integrated data processing concept. This program enables quantitative and qualitative data to be combined at will, taking into consideration that evaluating criteria can be varied considerably. Results. The results demonstrate that patients over 60 have significantly more complications than patients under 60. Analysis of the influence of the factors associated with surgical risk reveals that factors related to the operation such as type, length, and extent do not increase the risk as much as the numerous accompanying illnesses in both age groups. As far more elderly patients are affected by multimorbidity, the conclusion may be drawn that the increased risk observed is not due mainly to age, but rather to the patient's condition prior to surgery. The results indicate clearly that an exact analysis of the initial condition as well as avoiding failure or malfunction of certain organs must have priority in both age groups.
