There appears to be a great similarity between all of the various types of Adult Respiratory Distress Syndromes (ARDS) in that they are all characterized by progressively increasing interstitial edema in the lungs and a reduced functional residual capacity. Early diagnosis is mandatory and therapy should be started as soon as there is a reasonable suspicion, based on the patient's injury or illness and the previous condition of his lungs, that acute respiratory failure is developing. Sepsis, shock, CNS or thoracic disease and trauma are important associated factors. Blood gas changes usually cannot be appreciated clinically until the respiratory problem is quite severe. Accordingly, serial blood gas analyses should be performed on any patient who has a reasonable chance of developing ARDS. We have found that changes in the estimated AaDO2 on room air are especially helpful. Any deterioration in the patient's clinical condition, blood gases or ventilatory effort should be considered as an indication for early ventilatory assistance. Control of the primary process, careful dehydration, high tidal volumes, and PEEP are the mainstays of therapy. Serial blood gases and careful observation of the patient's effective compliance are essential to determine the optimal ventilator setting and the optimal amount of PEEP. Recently intermittent mandatory ventilation (IMV) with very large amounts of PEEP have been reported to be of value. Early administration of massive steroids should be considered if the patient fails to respond promptly to correction of the underlying etiologic problem, particularly sepsis, careful progressive dehydration and optimal expansion of the alveoli, with high tidal volumes and PEEP.

A single dose of surfactant TA was given as rescue therapy to four small premature infants with severe respiratory distress syndrome requiring mechanical ventilation. Birth weights ranged from 810 to 1200 gm. The dose of 100-120 mg/kg was given at the mean age of 5 hours, with range of 3 to 7 hours. Following surfactant therapy, there was a significant improvement (p < 0.05) in a/APO2 (raising from 0.11 +/- 0.05 before treatment to 0.34 +/- 0.19 at 6 hours after treatment). There was also a significant reduction in the severity of respiratory distress syndrome at 24 hours post-therapy. One baby died of sepsis at 40 hours of life; one survived without complications. The other two cases developed severe bronchopulmonary dysplasia later. We concluded that early use of exogenous surfactant is beneficial in small premature infants with severe respiratory distress syndrome.

One hundred ten infants with congenital diaphragmatic hernia (CDH) developed life-threatening respiratory distress in the first 6 hours of life. Associated anomalies were present in 33%. Twenty-eight of 65 infants (43%) treated before 1987 (pre-extracorporeal membrane oxygenation [ECMO] era) survived after immediate CDH repair, and mechanical ventilation with or without pharmacologic support. Only two of 16 (12.5%) infants requiring a prosthetic diaphragmatic patch survived. Since 1987, 31 of 46 (67.4%) infants with birth weight, gestational age, and severity of illness similar to the pre-1987 group survived. All patients were immediately intubated and ventilated. Seven (four with lethal chromosomal anomalies) infants died before treatment, and 30 stabilized (partial pressure of carbon dioxide [PCO2] < 50; partial pressure of oxygen [PO2] > 100; pH > 7.3) and underwent delayed CDH repair at 5 to 72 hours. Fifteen did well on conventional support and survived. Fifteen infants deteriorated after operation: 11 were placed on ECMO with eight survivors, and four infants were not considered ECMO candidates. Nine babies failed to stabilize initially and were placed on ECMO before CDH repair (alveolar-arterial gradient > 600 and oxygenation index > 40), and seven survived. The overall survival rate was 80% at 3 months in this ECMO-treated group. Early mortality was due to inability to wean from ECMO (one), intracranial hemorrhage (one), liver injury (one), and pulmonary hypoplasia (one). Nine of 11 babies requiring a prosthetic patch in the post-1987 ECMO group survived (81.8%). There were three late post-ECMO deaths (3 to 18 months) of right heart failure (two) and sepsis (one). Symptomatic gastroesophageal reflux occurred in nine cases, six requiring a fundoplication in the bypass babies. Recurrent diaphragmatic hernia occurred in nine cases (five ECMO). The overall survival rate was significantly improved in the delayed repair/ECMO group (67% versus 43%; p < 0.05) and was most noticeable in infants requiring a prosthetic diaphragm (81.2% versus 12.5%; p < 0.005). These data indicate that early stabilization, delayed repair, and ECMO improve survival in high-risk CDH. Early deaths are related to pulmonary hypertension and can be reversed by ECMO.

Chest radiographs of 63 culture proven cases of neonatal septicemia were evaluated in this prospective study. Gram negative septicemia was responsible for 76.2% cases. Radiological abnormalities were observed in 27 cases (42.8%). Seven of these had no respiratory distress. The findings were right sided infiltrates (27%); hyperinflation (7.9%), bronchopneumonia (6.3%) and pneumothorax (1.6%). Increasing gestational age, late onset of illness (greater than 3 days) and presence of respiratory signs of distress had a positive correlation with presence of X-ray findings. Term newborns with respiratory distress of late onset sepsis (greater than 3 days) had significantly higher number (p less than 0.05) of abnormal radiographs. Presence of radiological abnormality neither influenced the clinical outcome nor was affected by the causative organisms. The practice of doing a chest radiograph routinely in cases of neonatal septicemia is justified irrespective of presence of respiratory signs of distress.

A 12-month-old black female with an unremarkable past medical history was admitted to the hospital with respiratory distress and fever without identified sepsis. Despite mechanical ventilation, the patient died as a result of respiratory insufficiency secondary to severe necrotizing bronchitis and bronchiolitis with pneumonia. Electrophoretic and biochemical analyses of the patient's hemoglobin showed the patient to be a double heterozygote for hemoglobin C (a beta chain variant) and hemoglobin G-Georgia (an alpha chain variant). This is the first report of this combination of hemoglobin variants.

Renal cortical necrosis, renal medullary necrosis, and combined renal cortical-medullary necrosis result from renal ischemia without vascular occlusion. Renal hypoperfusion and ischemic injury in infants have been ascribed to massive blood loss, hemolytic disease, septicemia, and severe hypoxemia. In a postmortem study we identified 82 cases among 1,638 autopsies during the 20 years between 1970 and 1989 in infants 3 months old or less at the time of death. The frequency of renal necrosis in autopsy cases increased significantly during the last 6 years of the study. The distribution of the renal lesion was cortical in 28, medullary in 23, and combined in 31. Forty infants carried diagnoses of congenital heart disease, 17 of asphyxial shock, 9 of sepsis, 3 of infectious myocarditis, 9 of major malformations, 4 of anemic shock, 1 of vascular malformation, and 1 of gastroenteritis and dehydration. A significantly higher proportion of babies with congenital heart disease had cortical involvement. Comparison of clinical characteristics revealed a significantly higher frequency of prematurity, respiratory distress syndrome, bleeding diathesis, and possibly sepsis in the children with congenital heart disease, suggesting that these factors are important in the pathogenesis of the renal lesion. Fourteen infants underwent cardiac catheterization; there was no demonstrable association between the renal lesions and the use of radiographic contrast medium. We conclude that severe congenital heart disease itself is a risk factor for life-threatening renal cortical and medullary necrosis.

The acute respiratory distress syndrome (ARDS) is a late complication in critically ill patients and its diagnosis is usually made when the syndrome is fully established. There is an increased interest in developing early markers that may help to identify ARDS in its initial stages. Calcitonin was recently reported as a useful serum marker to identify burned patients at risk for respiratory failure. We report a case with abdominal sepsis and ARDS, whose serum calcitonin level was 1000 pg/mL without other known clinical causes of hypercalcitoninemia and who died in multiorganic failure. The possible mechanisms of hypercalcitoninemia and its possible utility as marker of ARDS in critically ill patients is discussed.

A pilot study of the effect of exogenous surfactant (ES) on premature infants with respiratory distress syndrome (RDS) is reported. Each of the first 15 infants in this study received 200 mg/kg of natural surfactant (Curosurf) during the first day of life. Controls were 56 infants with RDS seen in the 15 months prior to the study. Within 5 minutes of starting ES, in all infants there was rapid and dramatic improvement in oxygenation and improvement in the average arterial/alveolar ratio of 169%. They had lower oxygen and ventilatory requirements than the control group throughout the first 5 days of life. No treated infant suffered from pulmonary air leak, while in the control group 21% developed pneumothorax and 11% had pulmonary interstitial emphysema. Mortality was 13% in the treated group as compared to 27% in the control group (p less than 0.01). There were no differences between the groups in the incidence of sepsis, patent ductus arteriosus, necrotizing enterocolitis, intraventricular hemorrhage, or bronchopulmonary dysplasia, nor were there side-effects of therapy. Dosage, timing and composition of the ideal surfactant are important questions for future studies.

A grave complication of sepsis is a respiratory distress in adult persons observed by the authors in 11.3% of the examinees. The syndrome of respiratory distress could develop in the presence of toxico-infectious (septic) shock or severe allergic immediate responses to the administration of certain drugs. The main approaches to the treatment of respiratory distress in adult septic patients turned to be glucocorticoids, heparin and recurrent sessions of hemosorption.

In a prospective study, 1156 blood specimens collected from hospitalized febrile obstetrical-gynecologic patients and neonates with suspected sepsis, were inoculated into a conventional biphasic culture medium, Castaneda S and cultures incubated aerobically. 15-24 h later the broth cultures were subcultured to specific media for detection of mycoplasmas. Genital mycoplasmas were isolated in 15 samples (taken from 8 women) and in 2 from 1 neonate. Mycoplasmas and members of the family Enterobacteriaceae were the most frequent significant bacteria isolated from adult specimens. Mycoplasma isolations were associated with either postpartum or postabortum febrile infections in women. Four of the neonates, whose mothers were infected, showed respiratory distress at birth; 1 of them had mycoplasmas in the blood. All febrile states in obstetrical or gynecological patients, and in neonates, should routinely lead to blood cultures for detection of mycoplasmas and ureaplasmas.
