Patients (38) in whom total hip replacement was performed using a hypotensive anesthetic technique with moderate hemodilution were studied. Patients (17) operated on during normotension without hemodilution served as controls. Halothane, d-tubocurarine and pentolinium tartrate were the agents used. During the operation circulation was monitored carefully. Hypotension with hemodilution decreased the amount of the transfused blood to 1/3, compared with the normotensive group. The bloodless field during the hypotension shortened the duration of the operations. No complications attributable to the hypotensive technique occurred. The hypotensive anesthetic technique with hemodilution reduces the need for blood transfusion in major surgery. Only patients in good cardiovascular status are suitable for this technique, and careful monitoring of the circulation is mandatory during the anesthesia.
