Comparative Study[High-frequency jet ventilation with the HFV 970 prototype in laryngeal microsurgery: comparison of 2 injection systems].
To describe the results obtained with the use of a high frequency jet ventilation system with the HFV 970 prototype through two types of injector, an intratracheal cannula and an endotracheal tube, in 12 patients undergoing laryngoscopic microsurgery. ⋯ Our results for the efficacy of ventilation and oxygenation with the prototype HFV 970 are similar to those published for conventional high frequency jet ventilation. Using a tracheal tube assures adequate ventilation, but supposes a tendency to entrapment, whereas use of an intratracheal cannula is associated with lower ventilatory efficacy and less entrapment. Oxygenation is excellent with both systems.

Randomized Controlled Trial Clinical Trial[Efficacy of the ilioinguinal and iliohypogastric block in the treatment of the postoperative pain of inguinal herniorrhaphy].
The ileoinguinal-ileohypogastric block (IHB) improves pain control in inguinal hernioplasty. ⋯ IHB decreases pain, delaying the need for a first dose of analgesic and improving patient comfort. Its use is therefore recommended for relief of postoperative pain.

Case Reports[Pain in the lower extremities after subarachnoid block with lidocaine].
Subarachnoid block is a widely practiced anesthetic technique. With the availability of small-diameter needles and the rises in out-patient surgery, the number of procedures performed with subarachnoid block and short-term local anesthesia have increased. ⋯ We analyze the factors that might have triggered this complication and compare the two patients with 14 others described in the literature. Three points in common were found: the use of hyperbaric lidocaine, administration of the agent through small gauge needles and the performance of out-patient surgery.

Case Reports[Chronic subdural hematoma secondary to an accidental dural puncture during lumbar epidural anesthesia].
We report the case of a 54-year-old woman with cephalea of five months duration caused by a chronic subdural hematoma that appeared after epidural anesthesia and accidental dural puncture for bilateral saphenectomy. Computed tomography of the brain revealed an intracranial hematoma. After surgical evacuation, the patient's headaches resolved and she recovered fully. The appearance of cephalea after dural puncture is a relatively frequent complication of spinal anesthesia, but its persistence over time, as well as changes in its initial characteristics, should lead to a suspicion of life-threatening subdural hematoma.
