The incidence of serious hypotension must be considered a critical complication of anesthesia as far as coronary and/or cerebral risk patients are concerned. One must expect myocardial ischemia as shown by ECG changes in patients with cardio circulatory disease who suffer hypotension lasting longer than 10 min [10]. Likewise, a pressure-dependent, restricted cerebral blood flow might result in serious hypoxic brain injuries. A severe reduction in blood pressure can thus be responsible for grave sequalae [7]. One should be aware of the frequency with which hypotensive reactions occur during different anesthetic procedures in order to take the most effective preventative measures.
