[Clinical experiences with diazepam (Valium) - fentanyl combination anesthesia in neurosurgery. A study of circulation and oxygen consumption].

This clinical study was performed on 13 neurosurgical patients. The mean age was 56 years (range 45-70 years). After induction of anesthesia the heart rate diminished by 21.4%, the mean pressure by 12.2% in the same time decreased the cardiac output by 19.3%, the calculated total peripheral resistance increased by 13%. The oxygen uptake decreased by 16%. The advantages and contraindications of this technique in neuroanesthesia are discussed.
