Premature infants are at high risk of developing neonatal jaundice due to immaturity of liver function, which results in the inability to optimally conjugate bilirubin. This study aims to determine the effectiveness of Oral Motor Stimulation (ORMS) for increasing weight gain in premature infants with neonatal jaundice. One intervention is Premature Infant Oral Motor Intervention (PIOMI).
Premature infant care was provided to premature infants at risk of neonatal jaundice in the Perinatology Ward of 'Aisyiyah Ponorogo General Hospital. PIOMI was administered to infants at 29 weeks gestation and weighing 1,500 grams daily for 15 minutes for five days. The method used was a bleeding process approach. Daily weight was measured using a Fenton chart. The progression of neonatal jaundice was assessed using the Kremer assessment..
The study results showed that the infant had mild jaundice (Kramer II), characterized by a yellow discoloration of the face and chest. In addition to the jaundice, the infant experienced weight loss of up to 12%, compared to a birth weight of 1,500 grams. At the time of assessment, the infant's respiratory status was stable, the sucking reflex was absent, and the swallowing reflex was still very weak. The infant weighed 1,320 grams. After five days of PIOMI administration, there was an improvement in sucking ability, an average weight gain of up to 80 grams per day, and a decrease in signs of jaundice to Kramer I. It can be concluded that oral motor stimulation is effective in improving sucking ability, improving nutritional status, and helping reduce the risk of neonatal jaundice in premature infants. This intervention is recommended as part of nursing measures to optimize growth and prevent complications in premature infants.
