RESUMO
Laparoscopic herniorrhaphy has been criticized because of the need for general anesthesia. The endoscopic preperitoneal approach allows the use of epidural anesthesia, obviating the potential complications and side effects seen with general anesthesia. The purpose of this study was to determine the efficacy of epidural anesthesia for preperitoneal herniorrhaphy. Fifty-two patients underwent repair of a total of 80 hernias over a 6-month period. Thirty-six patients underwent their repairs with the use of epidural anesthesia with the goal of a T-4 sensory level. A tension-free prosthetic repair was performed in all patients. Seventeen patients had unilateral repairs and nineteen had bilateral repairs under epidural, while seven patients had unilateral repairs and nine patients had bilateral repairs under general anesthesia. There were no significant differences in patient demographics. All herniorrhaphies were electively performed on an outpatient basis by a single surgeon (A.L.S.) in a teaching setting. There were no significant differences for unilateral and bilateral repairs when type of anesthesia was compared. There was only one conversion from epidural to general anesthesia, secondary to poor sensory blockade first noticed during creation of the preperitoneal space (97% success rate). Seven patients receiving epidural anesthesia experienced pneumoperitoneum during the procedure. This did not effect the ability to perform the hernia repair successfully. There were no complications related to the epidural anesthetic. Endoscopic preperitoneal herniorrhaphy can be performed effectively under epidural anesthesia, obviating the need for general anesthesia.

The effectiveness and safety of etidocaine during extradural anaesthesia for Caesarean section were evaluated in 81 patients. Adequate sensory analgesia occurred in 78 patients and muscle relaxation was excellent in all patients. The combined umbilical venous-umbilical arterial/maternal venous ratio was 0.28+/-0.2 following the administration of 1% etidocaine 25 ml with adrenaline and 0.38+/-0.2 following the administration of 1% etidocaine plain 25 ml. Neurobehavioural patterns of the newborn were not affected noticeably. Etidocaine, in appropriate dose and concentration, appears to be an excellent local anaesthetic agent for Caesarean section under extradural anaesthesia.
