Angiotensin-converting enzyme in human adult respiratory distress syndrome.

Angiotensin-converting enzyme (ACE) levels, complement activation, and intravascular coagulation were studied in 36 patients with adult respiratory distress syndrome (ARDS) (17 aseptic, 19 septic), in order to investigate the possible interrelations among ACE, immunologic data, and hematologic findings. The severity of respiratory impairment was assessed with measurements of mechanical and gas exchange functional qualities of the lung. Serial measurements of ACE could be done in 14 patients during an eight-day period. During the first 24 hours, ACE levels were always normal (38 percent) or decreased (62 percent). No difference could be found between patients with septic and aseptic ARDS. Complement activation occurred in 78 percent (28/36) and used, in most cases, the classic pathway with presence of circulating immune complexes. Criteria for intravascular coagulation were present in 58 percent (21/36). No relation between coagulation, complement, and ACE could be found except for the patients with a greater respiratory impairment, who had complement activation, intravascular coagulation, and significantly lower ACE levels. In all patients together, ACE levels had no diagnostic value for aseptic cause of ARDS and a poor prognostic value. Only intravascular coagulation was linked with a higher significant mortality and a greater functional impairment. Serial measurements showed a diphasic evolution of ACE levels, with a maximum decrease between the 72nd and 96th hours and a further normalization (seventh day). The persistence of low levels seemed to be associated with evolutive sepsis or secondary aggravation and fibrosis.

[Acute pulmonary edema in carbon monoxide poisoning. Prognostic effect].

285 patients affected by carbon monoxide poisoning were admitted in our intensive care unit over a period of two years (from july 1980 to july 1982). 18 patients had a pulmonary edema (P.E.). The occurrence of P.E. was more frequent when coma was grade 2, 3 or 4 (p less than 10(-3]. The acute physiologic score (weighting of physiologic measurements) as proposed by Knauss is higher in patients with P.E. (p less than 10(-2]. However death is never due to P.E.; about 54 patients with coma, 5 died; death is related to neurologic aggravation. Neurologic sequelae are not related to the occurrence of P.E. but to a delay in hyperbaric oxygen therapy. These date show that prognosis of carbon monoxide poisoning is related to neurological status and is not influenced by the occurrence of P.E. when correctly treated and when hyperbaric oxygen therapy is early realized.

Intravenous nitroglycerin in acute respiratory failure of patients with chronic obstructive lung disease, secondary pulmonary hypertension and cor pulmonale.

We have studied the hemodynamic effects of an intravenous single dose of nitroglycerin in 13 patients with secondary pulmonary hypertension and Cor Pulmonale, during the acute course of respiratory failure and under assisted ventilation. We observed a significant decrease in systolic, diastolic and mean pulmonary arterial pressures, and in pulmonary resistance and systolic right ventricular work index, without any change in right or left pre-loads. The systolic arterial pressure decreased slightly, without any change in cardiac index or diastolic pressure. The arterial and mixed venous oxygen contents, and the pulmonary shunting ( Qs/Qt) were unchanged. These results suggest that nitroglycerin may be a useful therapy in patients in the acute stages of pulmonary hypertension resulting from chronic lung disease and under assisted ventilation. In addition, the lack of change in cardiac index, intrapulmonary shunting and oxygen content suggests that this decrease in pulmonary resistance is not linked with any deleterious effect in oxygen transfer.

[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.
