[Definition and realization of a microprocessor system for monitoring during artificial ventilation (author's transl)].

A medical application of a microprocessor system is presented. The definition of a system able to control the quality of the respiratory exchanges for a patient submitted to artificial ventilation is given. The measurement system is composed by two rapid analysers of CO2 and O2 (Beckman LB2 and OM 11), a flow meter devices and an airway pressure sensor (Monaghan M 700). The monitoring of the ventilation is based on the determination of FAECO2 simultaneous the determination of FECO2, FIO2, FEO2 and FAEO2 allow, with the sequential entries of the blood gaz values, to calculate: VA/V, D (a--A) CO2, D (A--a) O2, VO2, VCO2 and respiratory quotient. Now, we are working out a system composed by: a microprocessor (Intel 8080) which allows acquisition and treatment of the signals; a peripherical with a key board for the dialogue between the operator and the system; a visual display unit and a printer. Measurements are made on the patient every 13 mn during five respiratory cycles. All the stated above parameters are then computed. When there is a variation of FAECO2, an alarm is triggered, of predeterminated threshold is exceeded. This system simple, not too expensive, not invasive, has been conceived to work on one to four patients.

[Influence of the use of a video device for monitoring and visits on psychologic relations between patients, families and medical staff in an intensive care unit (author's transl)].

The use of a video device for monitoring and familial visits in a medical intensive care unit has various effects on psychologic relations between the patient, his family and the medical staff. Such a device is used since 1972 in Lille and has concerned more than 10,000 patients. On one hand, the monitoring of the patient is facilitated. His dependence to the staff is enhanced and allows a better taking of responsibility from the nurses and a good adhesion to the cares. At last, the video device gives to the patient and his family a real feeling of security during the early phase of the hospitalization. On the other hand, and particularly after this early phase, the use of a video device has deleterious effects on the psychologic relations of the patient with his family: enhancement of the psychologic regression, creation of an additional agression which jeopardizes the restoration of normal relations after attempt of suicide or prolonged artificial ventilation. This underlines the need for a real psychologic management of the video device in the reception of the families and the frequency of the relations with the medical staff.

[Rhabdomyolysis in acute intoxications (author's transl)].

During acute intoxications rhabdomyolysis appear with a great clinical polymorphism. The muscular involvement is not always evident because of its shortness and latence. Practically the problem is one of localised muscle damage, hyperkaliema or acute renal insufficiency. The serum isoenzymes of CPK levels, the presence of myoglobinuria are necessary for the diagnosis. The most serious rhabdomyolysis depend on the added injury of respiratory muscles and myocardium. Many toxic substances can involve rhabdomyolysis but the most frequent ones are sedatives, carbonic oxyde, ethanol. Only the complications are treated.

[Meadows syndrome. A case history (author's transl)].

The authors, having studied a case of Meadows syndrome, confirm that this cardiomyopathy is a specific entity in pregnancy and the puerperium. They point out the difficulties in diagnosis, as Meadows syndrome seems to be diagnosis of elimination. They point out that a paraclinical balance has to be drawn up very fully on the biological and haemodynamic planes to confirm this condition. Finally, after a short discussion about the therapy, they tackle the problem of the prognosis for life and for future childbearing in these patients, which is determined by the persistence or absence of cardiac enlargement.

[Current aspects of gas gangrene, apropos of 47 cases collected over a 3-year period (1974-1976)].

On the basis of 47 cases of gas gangrene collected over the three year period between 1974 and 1976, the authors review the circumstances surrounding its development, the clinical features and the prognosis of the disorder which remains grave despite a well-defined therapeutic protocol combining surgery, antibiotics and hyperbaric oxygen. There would appear to be a real resurgence of the disease at the present time. Post-traumatic and surgical aetiologies predominate, giving rise to two types of gangrene: clostridial gas gangrene secondary to contamined wounds, with a quasi-constant vascular element, affecting predominantly the limbs, and nonclostridrial gangrene, the increasing prevalence of which involves essentially spetic abdomino-pelvic surgery. In the light of this study, prognosis would appear to be related to the underlying terrain in which the gangrene occurs, to certain features of the clinical picture and, above all, to the possibilities of early application of the complete therapeutic protocol. Strict prophylactic measures would alone seem capable of preventign the worrying increase in the number of cases of gas gangrene.

[Determination of global diffusion of CO2 and its partial components under assisted respiration. Technical problems and practical value in respiratory resuscitation].

A study of partial CO2 ductance has been performed in patients under assisted ventilation. The authors propose methods for simultaneous measurement of paCO2, PAECO2, PECO2 and PICO2. This methodology is used in patients presenting different conditions accounting for respiratory resuscitation: barbiturate poisoning with healthy lungs, bronchial stasis, acute lung involvement, obstructive bronchopneumopathy and pulmonary embolism.

[Disorders of hemostasis during intake of lipids].

Lipid emulsions based upon soya triglycerides and widely used in parenteral nutrition. Haematological surveillance of the patients, and in particular the study of coagulation, shows slight changes in platelet adhesiveness and a transient hypercoagulability state proportional to the concentration of the lipid emulsion. Nevertheless, these findings must be interpreted with the greatest caution, inasmuch as the laboratory tests involved are technically delicate. The results obtained may be contradictory according to the protocol used. Finally, in patients receiving intensive therapy, there are multiple factors (stress, prolonge;d bedrest, hypercatabolism) which may alter coagulation quite independently of the prescription of lipids.
