[Use of a ternary mixture of local anaesthetics for peridural anaesthesia during urgent caesarean operation. Report on 125 cases].

125 caesarean operations are conducted under peridural anaesthesia with a mixture of local anaesthetics containing per milliliter: 2.5 mg of bupivacaine, 2.5 mg of etidocaine, 12.5 mg of lidocaine, and 5.10(-6) epinephrine. The dose injected is 23.37 +/- 1.98 ml, the volume necessary for blocking a metamer being 1.18 +/- 0.10 ml/segment. Satisfactory analgesia is obtained in 119 cases (95.2 p. cent), with adequate muscle relaxation in all cases. Block anaesthesia occurs after 5.81 +/- 0.67 min, last 197 +/- 62 min, and enable incision after 8.80 +/- 2.55 min with extraction of the infant after 13.72 +/- 2.85 min in 25 "extremely urgent" cases. Apgar is 8.98 +/- 1.62 after one minute and 9.68 +/- 1.31 after five minutes. These results prove that under perfect circumstances it is possible to get out the baby in about ten minutes.
