Influence of Keroncong Music during Implementation of Kangaroo Mother Care to Physiological Response and Nursing Length of Low Birthweight Infants

Kangaroo Mother Care (KMC) is nursing care method for low birthweight (LBW) infants. Some care interventions in neonatal intensive care unit, such as infant massage, KMC and listening to music have advantage for infant growth in form of physiological responses and reduce LBW infant-nursing length. This study aimed to determine advantage of keroncong music toward LBW infant's response during KMC and nursing length. The study design was quasi experimental using pretest and posttest using control group design. Population was mothers and LBW infants implementing KMC. Samples were 60 infants taken by purposive sampling. Inclusion criteria determined for LBW infants were having weight 1,500 - 2,499 gram, without considering pregnancy age, having ability to suckle though still weak, not suffering breathing distress. Meanwhile, exclusion criteria were infants with congenital disorder, sepsis symptoms and infants during therapy photo. Statistical test used paired t-test, independent t-test with p value < 0.05 and confidence interval (CI) 95%. After third day of treatment, LBW pulse decreased 8.13 times/minute (p value = 0.000), respiration decreased 2.36 times/minute (p value = 0.000). Nursing length mean on the treatment group was 8.57 days, while the control group was 11.87 days (p value = 0.038). Temperature result was insignificant (p value > 0.05). In conclusion, keroncong music influences on decrease of pulse, respiration during KMC and length of infant nursing.
