Hip fracture is a common pathology in elderly patients. Intercurrent diseases, mainly cardiac and respiratory, often result in significant morbidity and mortality. Anesthesia for hip fracture can be provided by general or regional techniques. The combination of a lumbar plexus and posterior sciatic nerve block represents an alternative to neuraxial technique of anaesthesia such as spinal anesthesia (4, 6). We report a case of acute toxicity resulting in the injection of local anesthetics Ropivacaine and Mepivacaine in elderly patient. An elderly woman was scheduled for surgical repair of a fractured femur neck by dynamic hip screw synthesis. Anesthesia was realized by peripheral nerve bi-block (lumbar plexus and posterior sciatic block) (7). The patient experienced seizures and dysrhythmias twenty minutes after block completion and injection of the anesthetic solution [Ropivacaine 0.75%, administered for lumbar plexus block performed via the posterior approach (WINNIE) and Mepivacaine 1.5%, administered for posterior sciatic nerve block (LABAT)]. Cardiopulmonary resuscitation was successful. All signs of toxicity disappeared after injection of midazolam and atropine, intubation and 100% oxygen ventilation. We decided to proceed with surgery. The postoperative course was uncomplicated and made a full recovery.

Hip-flexed postures enlarging the pelvic diameter are used to improve the obstetric course of labour. Although most investigations show that lateral and sitting positions do not affect the spread of epidural analgesia, the effect of recently introduced hip-flexed postures has yet to be confirmed. This prospective randomised study included 93 parturients. Ropivacaine 0.1% 12 mL plus sufentanil 0.5 micrograms/mL was administered epidurally over a period of 6 min in one of four postures: sitting, right hip-flexed left lateral position, left hip-flexed right lateral position and supine 30 degrees lateral tilt as a control group. Left and right cephalad and sacral epidural spread were measured every 2 min over a period of 30 min. Pain relief, motor blockade and maternal and fetal side effects were noted. The total epidural spread was 15+/-0.3 dermatomes and the upper level of thermo-algesic blockade T7-T8 (range T3 to T10) in all groups. There were no differences between groups in left or right total spread or upper level of epidural blockade, time to maximal block or pain relief. There was no motor block nor any maternal or fetal side effects. The power of the study (1 - beta) was 93%. We conclude that, for the three hip-flexed postures tested, position does not influence local anaesthetic spread or symmetry of thermo-algesic blockade after induction of obstetric epidural analgesia.
