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").

Case Reports[Heart arrest during general anesthesia in a child with unrecognized Duchenne's dystrophy].
A three-year old child was anaesthetized by halothane. Cardiac arrest occurred soon after the injection of suxamethonium. Signs of rhabdomyolysis associated with hyperkalemia were present. The diagnosis of Duchenne muscular dystrophy was obtained afterwards.

[Creatine phosphokinases and serum and urinary myoglobin following a procedure in prolonged knee-chest position for the treatment of spondylolisthesis].
Rhabdomyolysis following the knee-chest position was studied in 15 patients scheduled for surgery for spondylolisthesis. A comparison was made between 11 patients scheduled for orthopaedic surgery: ligamentoplasty (6 patients), total hip prosthesis (5 patients) and 11 patients scheduled for long oral surgery. The measurements carried out were blood CPK before surgery, 4, 8, 12 and 24 h after the beginning of surgery, and at days 2, 3 and 4. ⋯ In this series, rhabdomyolysis was real. CPK was not a good index of the release of haematic pigments, the only dangerous ones. A qualitative search for myoglobinuria is suggested, this being followed, or not, by alkalization to prevent acute renal failure.

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.

[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.
