[Combined loco-regional anesthesia and intravenous anesthesia with propofol (Diprivan--Zeneca)]

It is the purpose of the study to outline the superiorities of combined anesthesia in 100 patients undergoing orthopaedic (25 cases) and orthopaedic surgery (75 cases) interventions. The average duration of the operation is 90 +/- 25 min, performed under continuous peripheral (40 patients) and central (60 patients) nerve block, using Propofol against the background of continuous i.v. infusion and spontaneous ventilation. Nerve block is done according to routinely adopted techniques. The initial infusion rate for propofol (Diprivan) is 5 +/- 1.3 mg/kg/h, followed by infusional rate securing sedation II-III degree according to Ramsey's scale (mean 4 +/- 1.2 mg/kg/h). In 92 per cent of patients the sedation level is estimated as very good. In 8 per cent switching over to TIVA (total intravenous anesthesia) is necessitated because of the incomplete nerve block. No cases of hypotension or other essential secondary effects are recorded. Subjectively the anesthesiological technique is accepted as very good by most of the patients.
