“…Roentgenograms show that days, and even weeks, may elapse before the lung is completely expanded. Coryllos and Birnbaum [5] found that a pressure of 14 cm. of water was necessary to inflate the atelectatic lung of the dog.…”

Department of Obstetrics (tantl Gynncology, th1e Mirthodist ]Api.SCOl Hospital')Brooklyn, Ac,, ) rk? THE initial gcasp after birtlh is normally a vigorouis ins)ira-tory effort thalt opens, the airways and some of the alveoli of the lUngs. It is the most importan1t eveent in every life, and is quite dlistinct from subsequent respirations. Once breathing, howNever irregular and shallow, has (leveloped, effective iiieans of augmenting it are available, but there is no one generally accepted measuire for initiating the first inspiration. If this does niot occur spontaneously, the life of the child depends lIponl the measures employed.The onset of respiration is believedl to be caused by clieruiical, rather than by physical factors. An explanation of this phenomenon satisfactory for our purpose is, that immediately after delivery, the placental circulatioin is markedly impaired by the contracting, retracting uterus. This results in a (liminution of the oxygen sulpply to the baby and a. marked increase of the carbon-dioxide tension in the blood which stimulates the respiratory centre to action. We are all born in a coiiditioil of a,pnea, but it is only when this state persists for an uniedulv long period of time that there is cause for alarm. In the majority of prolonged apnoeas the conistant increase in the carbon-dioxide tenisioni, plus the mieasures einployed by the obstetrician, result in an inspiratory gasp, and apprehension is relieved. More and(l mnore often this favourable outcome is niot experienced so easily sometimes, niot at all.It is in an effort to face this problem that this paper is presented.We shall deal only with severe ca,ses of respiratory depression and asphyxia. Clinically most of them correspond to w\-ha,t is known as " a.sphyxia pallida ", which term will be frequently employed. At other times w-e shall use the word stillborn, indicating in either case a, ba.by in a, state of shock, very pale, with a relaxed mnusculature and absent superficial reflexes, who ha,s not breathed, but whose circulation persists. As far as treatment is concerned there is another class of babies: those which are so deeply narcotized anid anmesthetized as to be in serious danger. AlthoughlThe investigation was aided by a granit from the Lindredge Research Fund of the Hospital.

“…Reisman (1902), Cameron (1948) and Humphreys and Berne (1\)70) referred to this mechanism in explaining the development of unilateral oedema. That hypoxic damage to alveolar capillaries does occur in association with chronic atelectasis was demonstrated by Coryllos and Birnbaum (1929). They studied the short-term effect of ligation of the bronchus in the dog, and concluded that the blood flow into the lung was reduced in proportion to the degree of lung collapse.…”

Unilateral pulmonary oedema is a rare complication in the routine management of spontaneous pneumothorax. Previous reports have emphasized excessive negative intrapleural pressure, rapid re-expansion of the lung and bronchial obstruction as major factors in the pathogenesis. We have encountered four cases, and at least one of these factors have been absent in each case. Review of the literature, and our own experience suggests that the major factor is chronic and total lung collapse resulting in hypoxia and increased alveolar-capillary membrane permeability. Other factors which may be contributory are discussed.

“…Channels by which blood may bypass alveolar capillaries have been demonstrated in the proximal part of,the acini of the lung of man (Tobin, 1966), but it is usually assumed that the shunt of blood that occurs during anaesthesia is due to the passage of blood through collapsed areas of the lung Bendixen and Laver, 1965). Several workers (Coryllos and Birnbaum, 1929;Bjork, 1953;Bjork and Salen, 1950;Moore, 1931 ;Peters and Roos, 1952) have shown that when the lung of man or dog is made airless blood flow continues through the collapsed lung for several hours.…”
