Thus, it is essential to maintain the oxygen saturation within normal limits, which may necessitate giving more than the normal amount of oxygen during hypotensive anesthesia.
Hypotensive anesthesia may substantially decrease coronary blood flow.
18) All these factors result in oliguria during hypotensive anesthesia.
Since the aim of hypotensive anesthesia is to reduce blood loss and provide easily visualizes surgical field, the degree of reduction should depend on each individual patient and clinical situation.
CONTRAINDICATIONS: Contraindications to the use of hypotensive anesthesia are listed in Table 1.
Skin Necrosis: Necrosis of the skin with ulcer formation can occur after prolonged hypotensive anesthesia from pressure-induced hypoperfusion.
As a crucial prerequisite, the anesthetist conducting the hypotensive anesthesia must have a thorough knowledge of the technique that is to be performed.
