Fourteen preterm infants spent a mean of 23 hours divided into 4-hour periods with and without regular oscillations, 10 infants also being studied for control periods, before and afterwards. Electrocardiogram and impedance pneumogram were recorded continuously and analysed blindly. The waterbed, with or without oscillations, had no effect on apnoea or bradycardia when compared with control periods. Infants had appreciably more episodes of severe bradycardia while on the oscillating than on the non-oscillating waterbed.
14名早产儿平均花费23小时,分为有规律振荡和无规律振荡的4小时时间段,其中10名婴儿在前后还进行了对照期研究。连续记录心电图和阻抗呼吸图并进行盲法分析。与对照期相比,有或无振荡的水床对呼吸暂停或心动过缓均无影响。与在无振荡水床上相比,婴儿在振荡水床上时出现严重心动过缓的发作明显更多。
