[A Belgian surgical team at the Battle of Normandie in 1944].

During the year 1992, the main episodes of the battle of Normandy (1944) were commemorated with solemnity and dignity. The workmen of the victory, in what was called the greatest Battle of History, were essentially the American, British and Canadian troops. But, units composed of men from some European countries, particularly Frenchmen, Poles, Dutchmen and Belgians were also involved. Some of these units were engaged in action only at the beginning of August 1944, as soon as the whole peninsula of Cotentin, from Cael to Avranches, was firmly held by the Allied Forces and an offensive war through the Continent was considered. Apparently, the Allied Supreme Command had decided to preserve a reduced effective force of these units, during the most bloody phase of the battle for the conquest of a strong bridgehead. So they were kept in a position to participate in the liberation of their respective countries. In this paper, the author evokes a Belgian medical participation in the campaign of Normandy.

Etomidate infusion for laryngoscopy.

Reporting our experience with etomidate infusion in 37 cases of endoscopic examinations of the larynx, we recommend a method of general anesthesia ensuring easy examination conditions and rapid recovery. After premedication with atropine, IV Thalamonal is administered till obtention of somnolence. A dose of 0.25 mg/kg of etomidate is used for induction and an infusion at a rate of 25 mcg/kg/min for maintenance of anesthesia. Succinylcholine is used for intubation and whenever complementary muscular relaxation is required. Ventilation is ensured by the jet mixing technique with a manual injector. Fentanyl is given when reactions of tachycardia or arterial hypertension due to nociceptive stimuli are observed. The method described is safe, provides good conditions of anesthesia with complete amnesia and rapid recovery.

[Mortality in hospitalized psychiatric patients (results from a 5-year study) (author's transl)].

During 5 years we have registered mortality in 1239 chronic hospitalized psychiatric patients (609 men and 630 women) aged between 40-70 years in 6 German hospitals. We examined this patients on incidence of cardial riskfactors. The death rates were compared to the others of BRD. In this connection we found out an intensified mortality in all age groups of psychiatric patients as against to BRD average. The mortality of respiratory system diseases surpassed death rates of BRD many times better. Also psychiatric patients died by cardiovascular diseases more than expected. The death rates from ischaemic heart diseases in men were approximately twice as much than at BRD statistic. Patients who died in arteriosclerotic diseases had more often riskfactors than the other deceased. The great number of sudden and unexpected deaths was remarkable.

Studies on the effect of cyclophosphamide on Yoshida sarcoma ascites cells implanted into the colon wall of rats.

Yoshida ascites cells in doses of 10(3)X300, 500, 1500, and 3000 cells per animal were injected into the wall of the descending colon of 10 male Sprague-Dawley rats each. Doses of 10(3)X1500 cells and more per animal yielded a 100% rate of take-up of the graft. Whereas untreated control animals died medianly after 17 days, a single i.p. application of 70 mg/kg cyclophosphamide on days 8 or 10, respectively, after the tumor cell inoculation considerably prolonged the survival times. In both cases the median survival time amounted to more than 60 days. The application of the cytostatic drug 12 days after tumor cell implantation yielded only a slight increase in the median survival time (23 days). The introduction of this tumor model for screening new chemotherapeutics or combinations of chemotherapeutics to be used against colon tumors is discussed.

The risks of tracheal intubation.

Various lesions have been described as post-intubation complications: injuries, of usually minor degree, of the pharynx and larynx, oedema of the larynx, ulcerations of the pharynx and larynx with pseudomembranes and bleeding, chondromalacy of the larynx, granulomata, oesophago-tracheal fistula, stenosis of the larynx or trachea, paralysis and synechia of the vocal cords, paralysis of the tongue. Etiologic factors of these complications are mainly chemical, in relation with the material of the tube and with the sterilization agents, or mechanical due to pressure on neighbouring tissues. Post-intubation sore throat seems independent from traumatic laryngoscopy. Although intubation is meant to provide safer ventilation, interference with respiration may occur by compression of the tube or accidental obstruction from various causes. It should not be forgotten that in anesthesia cases, for which intubation is not really required, it may be advantageous to administer the anesthetic by mask.

Cerebral blood flow under enflurane anesthesia.

Cerebral blood flow was measured, under controlled conditions of stable ventilation and PaCO2, in 11 patients suffering from cerebro-vascular lesions. Comparing the results under N2O-enflurane 1% anesthesia with those under N2O-fentanyl anesthesia shows an average 8.4% decrease of blood flow. In 5 cases, a third measurement was performed under N2O-enflurane 2% anesthesia. This caused an average 8.5% complementary decrease. Whereas most inhalational anesthetic agents produce an increase of cerebral blood flow, this is not observed with enflurane, the tendency rather being towards a decrease.

Mobile intensive care unit. Present conception and realisation.

A new Mobile Intensive Care Unit has been put in use at the "Service 900" of the Ministry of Health in Belgium. Its size was decided to enable efficient treatment of one patient. The type of suspension was chosen to give the patient adequate protection against untoward effects of travelling sickness. Radio-communication with the control center and hospital is ensured. The O2 supply-system provides an autonomy of 11 hours. Besides an electric distribution of 12 V. DC, a 220 V. AC is also available.
