초록
산모(産母)와 태아(胎兒)에서의 CO 배출양상(排出樣相)의 차이(差異)가 hemoglobin의 CO와의 결합력(結合力)의 차이(差異)에서 기인(起因)된 것인지의 여부(與否)를 산소분압(酸素分壓)에 따른 HbCO의 해리양상(解離樣相)으로써 규명(糾明)하고 이를 토대(土臺)로 임신부(姙娠婦) 및 영아가 CO에 중독(中毒)되었을 때의 적절(適切)한 산소치료방식(酸素治療方式)을 모색(模索)하고자 본(本) 실험(實驗)을 실시(實施)하여 다음과 같은 성적(成績)을 얻었다. 1. 성인혈(成人血)과 태아혈(胎兒血)의 total hemoglobin량(量)은 각각(各各)
Breslau's report on the two stillbirths induced by illuminating gas poisoning made many investigators explore the hazards. of carbon monoxide(CO) poisoning to pregnancy. The pregnant woman, her fetus, and the newborn infant have been identified to be particularly vulnerable to CO even in low concentration. Several factors, such as placental barrier, membrane resistance of maternal and fetal red blood cells etc., were considered to be related to the delayed elimination of CO from fetus. Slower elimination of CO from fetus than from mother was confirmed in several in vivo studies. But there are few studies which have confirmed the difference of carboxyhemoglobin (HbCO) dissociation in adult and fetal bloods. Author investigated the effects of hemoglobin itself on the elimination of CO from mother and fetus. By observing the difference of CO dissociation from adult and fetal hemoglobin at the various partial pressures of oxygen, the author tries to suggest the base of the proper treatment measure for the CO poisoning of pregnant woman and newborn infant. The results were as follows: 1. The total hemoglobin amounts of adults and fetal bloods were
