作者以40对母婴为研究对象,探讨了妊娠期间主动或被动吸烟对局部缺血后血管反应性的影响。其中10例母亲(对照组)既不吸烟也不接触香烟烟雾;20例母亲(主动吸烟组)在孕期每天至少吸10支香烟;10例母亲(被动吸烟组)接触其丈夫吸烟的烟雾,其丈夫每天吸烟10支以上。所有母亲及婴儿均健康,在妊娠、分娩及产后5天内均无并发症。在分娩后第二天,作者对受试者的局部缺血后血管反应性进行了评价。他们用氧检测器(He llige)测定受试者的皮肤氧分压(tcPO_2)。其
In this study, 40 maternal and infant subjects were used to investigate the effect of active or passive smoking on post-ischemic vascular reactivity during pregnancy. Among them, 10 mothers (control group) neither smoking nor cigarette smoke; 20 mothers (active smoking group) took at least 10 cigarettes per day during pregnancy; 10 mothers (passive smoking group) exposed their husbands smoking smoke, Husband smoking 10 or more cigarettes a day. All mothers and infants are healthy and have no complications during pregnancy, childbirth and within 5 days of delivery. On the second day after childbirth, the subject evaluated the post-ischemic vascular reactivity. They measured the subject’s skin oxygen pressure (tcPO_2) with an oxygen detector. its
