[Experiences with hyperbaric bupivacaine solutions in spinal analgesia (author's transl)].
Spinalanaesthesia with hyperbaric bupivacaine (0.4%, 1.0%, 0.5%) was used in 713 patients having general surgical and urological operations. On average 19.30 +/- 1.55 mg bupivacaine was given and a spread of anaesthesia up to Th 7.21 +/- 1.55 achieved. Detailed evaluation of the 3rd group (0.5%) showed a latency period of 2.21 +/- 0.82 min and mean effective time of 4.33 +/- 0.75 h. The motor blockade was in 87% complete. The problem of the 0.5% solution with a specific gravity of 1.037 g/ml, which is in our opinion too high, was pointed out and a recommendation for a specific gravity of about 1.020 g/ml was given. Assuming proper positioning, spinal anesthesia with hyperbaric bupivacaine is a safe and simple anaesthetic method.
