[Alcoholemia and traumatology in S.A.M.U. 42].

This work was carried out over a year on all the wounded patients picked up by the S.A.M.

[Bacterial flora of 241 patients in an intensive care service].

The investigators performed an epidaemiological study of 260 patients in intensive care and identified the causal organisms by the obtaining of various specimens: tracheobronchial, urinary, blood cultures and catheter samples. By means of these specimens, they attempted to effectuate counts for each patient and the compare each month the patients definitely infected with the infections presented by the new patients. This study attempts to demonstrate the frequency of infections of the same kind when the intensive care unit consists of a single ward without separation of the patients and where the hospital staff treat all the patients in the unit in turn.

[Malignant syndrome caused by neuroleptics (3 observations)].

This study concerns 3 cases of malignant syndrome due to neuroleptics. Our aim is to clarify the nature of this syndrome and to attempt to delimit it from malignant hyperthermia. The etiology suggests that its occurence should increase with the growing use of very active neuroleptics.

[Apropos of complications following the use of methylmethacrylate. Possible prevention by betamethasone].

The aim of this study was to determine whether the prior injection of betamethasone was capable of preventing blood pressure changes and the fall in arterial pO2 when following the fixation of total hip protheses with methyl metacrylate. It involved 54 patients in whom systolic, diastolic and mean blood pressure (BP), arterial pO2, pCO2 and heart rate were noted at different times: T1, 15 minutes after the beginning of the operation; T2 and T3, one minute and five minutes after application of the cement; T4, at the end of the operation. There was no significant difference between the various measurements at times T1, T2, and T3 as far as blood pressure and heart rate were concerned.
