Multicenter Study[Anesthesia and intensive care of subarachnoid hemorrhage. A survey on practice in 32 centres].
To assess the current practices in anaesthesia and intensive care in patients experiencing subarachnoid haemorrhage (SAH). ⋯ Twenty-nine French and three non French centers answered the questionnaire. In 14 centers, more than 60 SAH had been treated in the previous year. Angiography was performed under sedation with a benzodiazepine associated with an opioid (54%). Criteria for choosing an endovascular approach were the site of the aneurysm (81%), its neck size (42%) and the underlying disease (42%). Anaesthesia was induced with either propofol (60%) or thiopentone (40%) associated with an opioid and a muscle relaxant. It was maintained with either isoflurane (59%) or propofol (41%). Nitrous oxide was often associated (62%). During anaesthesia, nimodipine (84%), mannitol (69%), anticonvulsants (47%), dopamine (31%) and lidocaine (9%) were also administered. Postoperatively, nimodipine was administered for prophylaxis of vasospasm (97%) and transcranial Doppler was employed to diagnose vasospasm (50%). Other techniques of care included hypervolaemia (89%), controlled arterial hypertension (36%) and haemodilution (36%).

Multicenter Study Clinical Trial[Anaphylactoid reactions to colloid plasma substitutes: incidence, risk factors, mechanisms. A French multicenter prospective study].
Changes in transfusion behaviour induce a widespread use of colloid plasma substitutes, the range of which has recently been enlarged by the marketing of starch derivatives. The product chosen depends, at least in part, on its adverse effects, anaphylactoid reactions being a part of these. This study aimed to discover the frequency and severity of these reactions according to the type of substitute available in France, to look for possible risk factors, and determine the mechanisms involved. ⋯ To conclude, it was shown that gelatins and dextrans should be avoided in patients with a known history of drug allergy. When a reaction does occur, an allergological assessment must be carried out, as this may be due to specific antibodies. Should this prove to be the case, that particular substitute would be contraindicated for the rest of the patient's life.

Multicenter Study[Information to relatives of organ donors. Factors of consent or refusal. Results of a multicenter study].
The French law on organ harvesting in brain dead patients allows this to be done without the family's consent, but prescribes to inform the relatives. Despite this, most teams do not harvest organs if the family is strongly opposed to the procedure. Information given to the relatives is therefore a very important point in the management of the donor. ⋯ This ratio, which did not depend on the hospital, increased with the age of the donor: 66% for donors aged less than 18 years to 86% for those more than 50 years old. The aetiology of brain death was not a factor determining acceptance of the donation. The main factor was the conditions of interview: acceptance rate was the highest when there was a one hour delay between giving the information on the donor's brain death and that concerning organ donation.(ABSTRACT TRUNCATED AT 250 WORDS)

Multicenter Study Clinical TrialDrugs and other agents involved in anaphylactic shock occurring during anaesthesia. A French multicenter epidemiological inquiry.
An epidemiological inquiry was carried out in departments of anaesthesia and immunology in French University and General Hospitals, as well as among those who were already known to have an allergo-anaesthesia outpatient clinic. This inquiry aimed to find out how many patients had undergone diagnostic investigations after as well as an anaphylactoid reaction during an anaesthetic in 1990 and 1991, as well as the demographic data, the kind of assessment, the accident mechanism and the drugs involved. Twenty-one French centres replied to the questionnaire and a series of 1,585 patients tested over a two-year period was thus collected. ⋯ Among these 1,585 patients, 813 were recognized as having had a reaction of immunological origin (52%). The substances involved were identified in these 813 patients as being muscle relaxants (70%), latex (12.6%), hypnotics (3.6%), benzodiazepines (2.0%), opioids (1.7%), colloids (4.7%), and antibiotics (2.6%). Suxamethonium was responsible for 43% of the IgE-dependent reactions involving a muscle relaxant, vecuronium for 37%, pancuronium for 13%, alcuronium for 7.6%, atracurium for 6.8% and gallamine for 5.6%.(ABSTRACT TRUNCATED AT 250 WORDS)

Review Multicenter Study Clinical Trial[Anesthetics responsible for anaphylactic shock. A French multicenter study].
Combined allergological and anaesthetic consultations have been started in the last few years in eight French Teaching Hospitals so as to explore peranaesthetic anaphylactoid shocks. A survey was carried out in these centers in order to collect patients investigated with the same protocol, for the assessment of the incidence of anaphylaxis in France, as well as the involved drugs. Investigations were always carried out at least 6 to 8 weeks after the accident. ⋯ It would therefore seem mandatory to carry out after any anaphylactoid accident an assessment with sensitive and specific tests for anaphylaxis. Diagnosing anaphylaxis means that the involved drug should be used never again in that patient. Because muscle relaxants are by far the most involved drugs, anaesthetists should use them only when really required.
