Background : The painful procedure of drawing blood from heel(HL) in the neonatal intensive care unit (NICU) is necessary for some diagnostic tests, but it can have negative effects on the physiological criteria of the preterm infants. The goal of this study is to compare the effect of lullaby and kangaroo care on the physiological criteria of preterm infants admitted to NICU during (HL).
Materials and Methods: This clinical trial with a crossover design was conducted on 60 preterm infants (30-36 weeks of gestation) admitted to NICU at Ali Ibn Abitaleb Hospital in Zahedan in 2019. The infants were randomly divided equally into two groups of lullaby and kangaroo care (n=30 in each group). In the former group, lullaby was played for infants through headphones for 30 min, and in the latter group, the infant was placed in the mother's arms for the same time. Physiological criteria were recorded before (0 min), during (15 min) and after the procedure (30 min). Data were analyzed using SPSS 22 software and independent T-tests and Chi square test.
Results: There was no statistically significant difference between the mean gestation age of neonates in the lullaby (32.63± 1.92) and kangaroo care (32.69± 1.92) group (p=1.000). The results of independent sample T-test showed that during the intervention, there was a difference between the mean pulse rate (P=0.015), respiration R (P=0.003) and arterial oxygen saturation percentage (P
