[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[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.

Comparative Study[Spinal anesthesia with isobaric 0.5% bupivacaine. Effect of age].
The effects of age on the characteristics of spinal anaesthesia with plain bupivacaine were investigated in 29 adult patients (less than 50 yr : group I), and 37 older patients (greater than or equal to 80 yr : group II). Three millilitres of 0.5% solution (15 mg) were injected at the L3-L4 interspace in the lateral position; the patients were turned supine immediately afterwards. The onset, extent and duration of sensory and motor blockade, the cardiovascular effects and the quality of anaesthesia were evaluated. ⋯ Only the Bromage's degrees 2 and 1 were greater in the elderly's group. In the older group, there was a tendency to a greater decrease in systolic arterial pressure from the preanaesthetic values (-20.9% versus -13%). But moderate falls in mean and diastolic arterial pressures were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

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.
