Mendelson's syndrome is discussed with a review of the literature and presentation of 27 personal cases studies. Accidental aspiration of gastric fluid occurs primarily during anesthesia, in cranial trauma victims, and in toxic coma patients. Tissue damage is proportional to the acidity and the quantity of aspirated fluid. The initial clinical manifestations are often serious, sometimes leading to acute respiratory distress syndrom with pulmonary edema. Frequent infectious complications, often with anaerobic microbes, are deciding factors in the prognosis. Artificial ventilation with positive pressure (sometimes continuous) is often necessary. Administration of corticosteroids at high doses is likely favorable. Prophylactic administration of antibiotics is initially directed against anaerobic agents. The prevention of this serious syndrome should be a primary concern of anesthesiologists and physicians treating comatous patients.

The consequences of near-lethal smoke inhalation in dogs were studied for a 72-hour period following injury. Progressive hypoxemia and decrease in compliance developed. Severe respiratory distress and frank pulmonary edema were not encountered. Respiratory insufficiecy was related more to alterations in ventilation perfusion ratios than to alveolar destruction. These data were related to clinical observations made by others. No deterioration of lung function was seen with crystalloid overload imposed upon smoke inhalation. The presence of bacterial infection in dogs surviving beyond 24 hours appears pathogenically significant.

Due to the interstitial pulmonary edema present in neonates with idiopatic respiratory distress syndrome (IRDS), it was believed furosemide would be useful in its treatment. In newborns with this syndrome, the effect of said diuretic was studied in blood gases, oxygen alveoloarterial difference and right to left short circuit. Twenty-two infants with similar clinical and laboratory characteristics were included in the study. Out of them, 11 were given furosemide (1 mg/kg/single dosis) and the remaining cases were controls. No difference was shown between both groups in PaO2 and PaCO2 and therefore, the alveoloarterial difference of oxygen nor the right to left short circuit during 60 minutes that the study lasted were either affected even if the infants who were given furosemide showed a significantly greater urinary flow. Due to the above results, the use of furosemide is not recommended for children with IRDS to eliminate an interstitial edema.

Children who have been exposed to smoke in a confined space or who have soot or burns, however minimal, on the face should be admitted to hospital. Respiratory distress may be delayed, but if it is progressive the patient should be curarised, intubated, and mechanically ventilated. Unless ventilation continues for 48 hours, followed by 24 hours' spontaneous respiration against a positive airway pressure, stridor and pulmonary oedema may recur. An endotracheal tube small enough to allow a leak between it and the oedematous mucosa must be passed to prevent laryngeal damage and subsequent subglottic stenosis. High humidity of inspired gases keeps secretions fluid and the endotracheal tube patent. A high oxygen concentration compensates for deficient oxygen uptake and transport caused by pulmonary lesions and the presence of poisonous compounds interfering with oxygen transport. Dexamethasone to minimise cerebral oedema and antibiotics to reduce the incidence of chest infections should be given.

Ruminal administration of 3-methylindole in goats severe pulmonary edema and respiratory distress. Electron microscopic studies of lungs reveal extensive degeneration and necrosis of alveolar membranous pneumocytes and bronchiolar epithelium. The necrosis of the pneumocytes is followed by proliferation of granular pneumocytes, which repopulate the alveolar basal lamina scaffold. 3-Methylindole may also induce proliferation of smooth endoplasmic reticulum in the remaining membranous pneumocytes and nonciliated columnar cells, indicating that these two cell types are involved in the xenobiotic function of the lung. The results suggest that 3-methylindole in cigarette smoke may play an important role in the pathogenesis of small airway disease and emphysema, and that patients with severe liver diseases or portocaval shunt may be predisposed to diffuse alveolar damage by 3-methylindole produced in the intestinal tract.

The study comprised seven children between 6-12 years admitted to Hospital Infantil "Lorencita Villegas de Santos" with progressive respiratory distress attended with cyanosis consistent with pulmonary edema. In all patients there was a previous history of a sudden change in altitude from sea level to 2,600 m. Changes consistent with pulmonary edema were made evident at the X-rays studies. The electrocardiogram showed right ventricular overload. No significant changes were found at the blood picture. All patients were treated with oxygen and rest; relief was attained within 72 hours.

After successful rescue from drowning there may develop a situation which is called secondary drowning, resulting in acute respiratory distress characterized by interstitial pulmonary oedema, hypoxaemia, hypercapnia and acidosis during drowning, direct alteration of the alveolar membrane by aspirated water and particulate matters and a volume overloading by adsorption and--not seldom--inept therapy. This situation requires mechanical ventilation and forced diuresis, combined with high doses of steroids, antibiotics and digitalis. We present the case of an eleven year old patient whose clinical course demonstrate the necessity of exact clinical observation after rescue from drowning. After development of acute respiratory distress only the immediate utilization of the therapeutic modalities of an intensive care may result in a satisfactory outcome. Four months later our patient had normal pulmonary function except for a moderate reduction of compliance.

The effects of intraruminal administration of 3-methylindole (3MI; skatole) were determined in goats. The 3MI was given to 4 goats at the dose level of 0.3 g/kg of body weight, to 2 goats at 0.2 g/kg, and to 2 goats at 0.1 g/kg; 3 nontreated goats were used as controls. Clinical signs of acute progressive respiratory tract disease were seen in all treated goats. Goats given the largest dose of 3MI (0.3 g/kg) died between 5 and 11 hours after treatment; those given smaller doses (0.2 and 0.1 g/kg) died between 79 and 92 hours. Increased plasma concentrations of 3MI were detected in goats give 0.1 or 0.2 g/kg within 3 hours after administration. By 24 and 36 hours, the concentrations of 3MI in the plasma decreased to low or nondetectable amounts and remained low for the duration of the experiment. Clinical signs of respiratory distress in the goats progressed after 3MI had been cleared from the plasma. Diffuse pulmonary edema and hydrothorax were extensive in goats which died early in the course of the experimentally induced disease. In goats which died at later stages, the lungs were firm and had less watery transudate. Temporal variations in the nature of pulmonic changes were even more obvious by microscopic examination. Diffuse pulmonary edema was the predominant early change. Small foci of emphysema were apparently caused by overdistention of some clusters of alveoli. Marked septal thickening and proliferation of alveolar cells were the prominent changes in goats which died between 79 and 92 hours after treatment. Incubation of L-tryptophan with caprine ruminal fluid resulted in formation of indoleacetic acid, indole, and 3MI. Similar incubations did not convert indoleacetic acid to 3MI. Control incubations showed 3MI as a fermentation metabolite, indicating it exists in caprine ruminal fluid in vivo. Results demonstrated that goats are susceptible to intraruminal administration of 3MI. The transitory appearance of 3MI in the plasma associated with progressive respiratory tract disease was similar to observations in cattle give 3MI. Clinical signs and lesions seen at necropsy were qualitatively similar to those reported in cattle given tryptophan and indoleacetic acid.

After injection of an anti-lung -serum a respiratory distress syndrome could be produced in spontaneously-breathing guinea pigs. Reduced compliance, increased resistance and work of breathing was found. Morphological investigations showed intraalveolar and interstitial bleedings and a lung edema. Biochemically a decreased total phospholipid content could be found. Surface tension characteristics, examined with the Langmuir balance, were deteriorated. A complete restitution of surface tension parameters and total phospholipid content was obtained by administration of bromhexin metabolit Na 872.
