Randomized Controlled Trial Clinical Trial
[Laryngeal edema after extubation. Do corticosteroids play a role in its prevention?].
The role of corticosteroids in the prevention of post-extubation laryngeal oedema was evaluated in a randomized study of 276 patients under mechanical ventilation. Fifty per cent of the patients received methylprednisolone 40 mg intramuscularly and intravenously. ⋯ Thus, the incidence of laryngeal oedema was not modified by corticosteroids. Regular prescription of corticosteroids does not seem to be useful before extubation of patients intubated with large volume, low-pressure balloon tubes.

Spinal analgesia, a new method for relieving refractory cancer pain, was tested in 19 patients. A catheter was installed in the subarachnoid (17 cases) or peridural (2 cases) space and connected to a subcutaneous site of injection. ⋯ In 11 patients pain was relieved throughout the course of the malignant disease, with doses that did not exceed 6 mg in 7 patients and 10 mg in the remaining 4 patients. The most severe complications were leakage of the cerebrospinal fluid in 1 case, meningitis after 18 months of injection in 1 case and displacement of the catheter in 3 cases.

The intracranial pressure of 31 patients with bacterial meningitis, in a comatose state and with a score lower than 6 on Glasgow's scale, was monitored by means of an extradural captor in order to detect intracranial hypertension and optimize its treatment. All patients had intracranial hypertension during the first 48 hours. ⋯ Twenty (64%) of the patient survived, 15 of them without sequelae. Monitoring intracranial pressure in patients with bacterial meningitis and coma makes it possible to optimize treatment and shows that a less than 50 mmHg brain perfusion pressure is associated with a 100% death rate.

Spontaneous dissection of the extracranial internal carotid artery is uncommon and has been first described in 1959. Since then, 250 cases have been published. The authors report on 5 recent cases and on that occasion, they review the literature and discuss the different therapeutic possibilities. ⋯ The spontaneous course of such a dissection most often (80%) leads to an almost complete resolution of clinical and angiographic signs. Treatment, therefore, should essentially be based on anticoagulant and antiaggregant therapy, so as to prevent ischemic attacks or carotid thrombosis. Surgical indications should remain exceptional.
