Case Reports[Anesthesia of the brain stem after a retrobulbar block. Description of 2 cases].
The Authors report two cases of central nervous system complications after retrobulbar block. These complications have a 0.044% incidence in 4500 subsequent cases of retrobulbar blockade studied from 1981 to 1990. The Authors attribute the respiratory arrest and coma to direct access of the anesthetic to the central nervous system along the subdural space in the optic nerve sheath.

Comparative Study[Tracheal intubation: increase of arterial pressure and cerebral blood flow velocity. Effect of thiopentone and propofol].
Induction of anaesthesia in intracranial surgery, especially for vascular diseases, must minimize haemodynamic changes: blood pressure and cerebral blood flow must not be increased to a high degree. Our work compares increases in blood pressure and in the speed of cerebral blood flow during endotracheal intubation in two groups of patients, who received propofol or thiopentone for the induction of anaesthesia. ⋯ Increase in blood pressure after intubation was lower with propofol than with thiopentone in a statistically significant way. Also the increase in the speed of cerebral blood flow, measured with doppler technique, was lower when induction with propofol was used, though not statistically relevant.

One hundred and thirty three patients of both sexes were operated on for pituitary tumors with transphenoidal microsurgery. Postoperative complications are discussed.

We present one case of pulmonary edema following intravenous naloxone administration for antagonism of residual narcotic drugs. The patient was a young man without cardiopulmonary or neurologic disease. Pathogenesis results from a massive sympathetic discharge which leads to neurogenic pulmonary edema.

A new technique for regional anaesthesia for arthroscopy of the knee is presented. The method includes sciatic nerve block according to the technique proposed by Labat, through a posterior approach and the block of the femoral and lateral cutaneous nerves using a single anterior approach. Results obtained in 30 patients are presented: they include good stability of the cardiovascular and respiratory parameters, high efficiency and duration of anaesthesia resulting in a satisfactory surgical procedure.
