The number associated with anesthesia deaths increased again. The reason is the disproportionate increase in the number of older and multimorbid patients, as well as the growing number of previously unthinkable in medicine surgical procedures. German doctor Andre Gottschalk calculated statistics of deaths from anaesthesia in recent years.
In the 1940 o years mortality from anesthesia was equal to 6.4 out of 10,000, but with the introduction of safety standards (pulse oximetry, for example), the value decreased to 0.4 by the end of the 1980s. This figure is still loyal to DL in patients without relevant systemic diseases. However, mortality in patients with concomitant diseases increased to 0.69. In the list of such diseases include heart failure, angina, chronic renal failure, severe malignant hypertension. Such patients can go for surgery due to modern advances in medical technology, one risk for them is still higher.
Others explain the increase in mortality from anesthesia is considered to be the growth of the elderly population worldwide, in Germany alone the number of people over 65 has increased from 28.8% in 2005 to 40.9% in 2009.
