Randomized Controlled Trial Clinical Trial[Spinal anesthesia with bupivacaine for surgery of the hip in the elderly].
In 60 elderly patients, spinal anaesthesia for orthopaedic hip surgery was induced randomly with 15 mg bupivacaine 0.375% without glucose (Group I), 2.5% glucose (Group II) or 7.5% glucose (Group III), in 4 ml. The injection was made in the lateral position, and the patients turned supine immediately after. The onset, extent and duration of sensory and motor blockade, the cardiovascular effects and the quality of anaesthesia were evaluated. ⋯ It was suggested to take into account the more rapid infusion of lactated Ringer's solution (20 ml X kg-1) in Group III. Anaesthesia was satisfactory in 95% of patients in Group I and Group II, and 90% in Group III. Glucose-free bupivacaine produced a long-lasting blockade suitable for hip surgery of long duration.

Case Reports[Contracture test with ionophore A 23187 for the diagnosis of malignant hyperthermia].
The results are reported of the contracture test obtained by using the calcium ionophore A 23187 (Calcimycin) in two patients, the son (A) and the mother (B). The past history of patient A revealed the occurrence of an impending malignant hyperthermia crisis during induction of anaesthesia in 1975. ⋯ It is suggested the A 23187 contracture test be added to the contracture tests as defined by the European Malignant Hyperpyrexia Group. This test could be of great help in identifying the percentage of relatives of MHS ("malignant hyperthermia susceptible") patients found to be MHE ("malignant hyperthermia equivocal").

[Femoral nerve block as a postoperative analgesia technic in surgery of the knee].
A femoral nerve block was performed as a postoperative analgesic technique in 50 patients after knee surgery; this surgery is a very painful one. The technique used was the inguinal route, as described in the textbooks. ⋯ The average duration of analgesia was 600 min, the shortest being 300 min, the longest being 1,200 min. This technique can be recommended after surgery of the knee as safe and reliable.

Randomized Controlled Trial Comparative Study Clinical Trial[Maintenance of obstetrical analgesia by continuous perfusion into the peridural space].
Two methods of epidural analgesia were compared in two randomized groups each of 16 normal women in labour, using bolus or continuous infusion. Analgesia was provided by a mixture of bupivacaine 0.25% and fentanyl. ⋯ There was no statistical difference between the two groups concerning length of labour, number of forceps, Apgar score and patient, obstetrician and anaesthetist satisfaction score. Although continuous epidural infusion was greatly appreciated by the obstetrical team, it would seem to be of interest only when labour is long enough to require larger doses, especially when labour is induced.

Case Reports[Expiratory blockage of a Monnal S respirator caused by rupture of the capsule of a pneumatic Bennett valve].
In the recovery room, a ventilated patient suddenly developed bradycardia and severe cardiovascular collapse due to increased airway pressure. The cause of this life-threatening complication was continuous occlusion of the expiratory valve by a ruptured diaphragm in a Bennett's valve. ⋯ On expiration, the expiratory gas under pressure penetrates the ruptured capsule, maintaining the valve occluded. A small part of the expired gas escapes through the small-bore connecting tube of the diaphragm.
