[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.

[Brachial plexus block in children. Approach through the brachial canal].
This study included 35 children (average age: 8 years) undergoing surgery of the upper limb under brachial plexus block. The brachial plexus was approached by the brachial canal route, which is a simple, rapid and efficient way (34 were successful). ⋯ In addition, postoperative analgesia was satisfactory in all cases. In spite of large doses and volumes of lidocaine and bupivacaine used with this technique, no complication was observed.

Case Reports[Practical approach to complex acid-base disorders using a slide rule].
Diagnosis of mixed acid-base disturbances is often difficult. Nowadays it depends on biochemical and statistical interpretation, coupled with clinical data. The acid-base slide-rule is a useful tool to carry out this five step procedure, which it simplifies, giving rapidly at the patient's bed-side an objective support for the diagnosis of acid-base disturbances.
