This study was performed to evaluate possible physiological and behavioural changes in healthy neonates(n.) during heelstick procedures(h.p-).25 n. in room air and without severe perinatal complications (Minde s.<4)undergoing h.p. for bilirubin, glycem., ht., in the first 2 wks of life, were included in the study(G.A. wks 34±3;B.W. g.1935±580;Apgar s. 5m. 8.5±1). Behavioural states(B.S.), transcutaneous oxygen tension(Tc PO2), heart rare(H.R.)and respiratory rate(f.) were monitored 3m before and after h.p. and during h.p. that lasted from 20″ to 240″ x=132″. Data were sampled at 10″ intervals using a timer and an audiotape. Variables were compared between periods before, during and after h.p.(p.t tests).B.S. increased from 2.9±0.9 to 5.6±0.5 during h.p.(p<.001), with behavioural distress lasting after h.p..H.R. increased from 138±14 before h.p. to 168±19 during h.p.(p<.001)and remained elevate after h.p. TcPO2 did not change and f. decreased from 48±10 to 40±10 during h.p.(p<.01)but recovered rapidly after h.p. Our n. react to h.p. with fussing, crying and H.R. increasing; f. decreased briefly without impairing oxygenation.
