Popis:	Previous reports have indicated that newborns react to maternal voice by deceleration of heart rate (HR) and respiratory rate (RR). We examined whether transcutaneously measured blood gases (TcPO2, TcPCO2) as well as HR would be altered by a recording of the mother's voice during the 1st and 2nd days after birth. Thirty healthy, appropriate-for-gestational-age (AGA) newborns (17 males, 13 females) with normal Apgar scores and various ethnicities were monitored for TcPO2, TcPCO2, and HR in a quiet room (Prestim). The newborns were then exposed to a tape of their mother's voice (65-75 dB) for 5 min while monitoring continued (STIM). An additional 5 min of monitoring without stimulation followed (POSTSTIM). TcPCO2 was significantly elevated vs. Prestim both on day 1 (STIM 1.9 ± 0.6, Poststim 2.3 ± 1.2 mmHg) and on day 2 (STIM 1.4 ± 0.5, POSTSTIM 1.4 ± 1.2 mmHg). TcP02 was not altered during STIM or POSTSTIM on either day. HR showed a decline during STIM on the 2nd day only (-4.3 ± 2.8 beats/min); however, th...
