Abstract
Nine infants of 26-29 w PMGA (BW 780-1270 g)were exposed to the mother's voice from a tape recorder via loudspeaker (at∼70 dB) 5×30′ a day between 29 and 38 w PMGA(for X 8.2 w) after conditions were stabilized. At 2 days each week the babies' behaviour (applying an A rating from 1 =quiet sleep to 6 = crying) and tcPo2 was recorded every 10″ for 1 hour, once without and once with m's voice (30′ after 30′“base line”).
Results: A and tcPo2 varied significantly during tests In 43-57 percent of “blanc” observations and with m's voice (table), but in the latter case significantly more often A level fell (Δ X-.5 points; p<.001) and tcPo2 level rose (ΔX +.4 kPa; p<.005) during stimulation. Means of 15′ periods of A and tcPo2 correlated inversely (r=-.55).
Conclusions: 1) Premature infants react to acoustic stimuli after 28 w PMGA, If hearing is unimpaired and/or stronger stimuli do not Interfere. 2) M's voice can tranquilize the baby increasingly reproducible causing a transient increase of tcPo2. 3) Recorded m's voice may serve as a substitute, if the mother cannot stay with her baby, to the benefit of both.
