[Prone position and severe pneumopathy in a patient with head injuries and intracranial hypertension]. / Décubitus ventral et pneumopathie sévère chez un patient traumatisé crânien avec hypertension intracrânienne.

The treatment of hypoxaemia is one of the main goals of intensive care to patients with severe head injury. In the case reported here, the appearance of early pneumonia was accompanied by a severe deterioration of blood gases with worsening of intracranial hypertension. Prone position allowed rapid improvement of blood gases which contributed to the control of intracranial hypertension.

Does noninvasive ventilation reduce the ICU nosocomial infection risk? A prospective clinical survey.

OBJECTIVE: To observe the nosocomial infection (NI) distribution in ventilated patients of a single intensive care unit (ICU) according to the kind of control of the upper airways: noninvasive positive pressure ventilation (NPPV) versus endotracheal intubation (ETI). SETTING: ICU of a general hospital. DESIGN: Prospective clinical and epidemiologic survey. PATIENTS: In the period December 1994-March 1997, 761 patients were included who needed mechanical ventilation for more than 48 h: 129 were ventilated by NPPV (NPPV group), 607 were intubated (ETI group) and 25 required intubation after a period of NPPV (NPPV-ETI group). MEASUREMENTS AND RESULTS: The data used were prospectively collected according to the NI epidemiologic surveillance protocol of "C. CLIN Sud Est, Réa Sud Est", France. NI included a ventilator-associated pneumonia (VAP), catheter-related infection, urinary tract infection and bacteremia. Occurrence of NI was estimated by the density of incidence. Covariate-adjusted NI and VAP risk factors were assessed by the Cox model. The incidence density of total NI was lower for NPPV than for ETI (14.2 versus 30.3 per 1000 patient-days, p < 0.01). The Cox model showed that the use of noninvasive ventilation, adjusted to the severity of illness (SAPS II), reduced not only the VAP risk (hazard ratio (HR) = 4.07) but also the NI risk (HR = 1.95). CONCLUSION: The use of NPPV reduces the risk of VAP and NI, compared to ETI, irrespective of the severity of the patient's illness.

[Aortic dissection and pregnancy. Apropos of a case]. / Dissection aortique et grossesse. A propos d'une observation.

Aortic dissection is a serious disease which rarely affects young women. In this context, it occurs in nearly one out of two cases during pregnancy, usually during the third term. The authors report acute dissection of the ascending aorta (de Bakey type 2) during pregnancy for which rapid cardiothoracic surgical management as a semi-emergency resulted in a favourable outcome for mother and child.

Short- and long-term prognosis, functional outcome following ICU for elderly.

Among 1532 ICU patients we analysed 295 elderly patients (19%) aged more than 70-years-old. We determined prospectively the immediate and subsequent one-year outcome with a study of the predictive value of their ICU admission parameters. Then we followed the ICU survivors over the year after discharge (1, 6, 12 months) by quality of life questionnaires. ICU mortality was 26.7%; SAPS was the only predictor of short term mortality. On ICU discharge, 216 elderly were followed at 1, 6, 12 months; the one-year cumulative mortality was 49% from ICU discharge, majority of deaths occurring over the first month. Age, previous health status and SAPS had a predictor value of one-year mortality for ICU survivors. 103 patients were alive at one year: 88% returned to home, 72% had a relatively good functional status allowing an independent life, and 82% had the same or improved functional status.

Superior vena caval thrombosis and recurrent pericarditis caused by a bronchogenic cyst.

A 49-year-old man with a past history of multiple episodes of acute pericarditis was admitted with a recurrence of symptoms combined with the superior vena caval syndrome. A bronchogenic cyst, located beneath the carina, was discovered. At operation, the cyst was partially resected, and superior vena caval flow was restored by a Gore-Tex prosthesis. Ten months later the superior vena caval syndrome reappeared. Angiography demonstrated subtotal stenosis of the graft, which was considered to be thrombotic due to the discontinuance of oral anticoagulants. Reoperation, however, showed no thrombosis, but kinking of the graft. The folded portion of the prosthesis was resected, since when the patient has done well.
