Participants in the Gentle Touch Group received the gentle touch technique during painful procedures. The researcher warmed her hands and gently placed one hand on the infant's head and the other hand on the abdomen while maintaining the infant in a supine position inside the incubator. The gentle touch technique was initiated before the painful procedure and continued during the procedure and for a short period after completion of the procedure. The total duration of the intervention ranged from 7 to 10 minutes. The intervention was performed by the researcher under the supervision of the neonatal intensive care unit nursing staff.

Participants in the Control Group received routine neonatal care during the painful procedures without the application of the gentle touch technique.

Pain levels were assessed using the Neonatal Infant Pain Scale (NIPS), and respiratory parameters including respiratory rate and oxygen saturation were measured before, during, and after the painful procedure

Participants in the Control Group received routine neonatal care during painful procedures without applying the gentle touch technique.

The gentle touch technique was applied to preterm infants during painful procedures. A total of 60 preterm infants participated in the study. Thirty infants were assigned to the intervention group and received the gentle touch technique, while the other thirty infants were assigned to the control group and received routine neonatal care without the gentle touch intervention. The researcher gently placed one hand on the infant's head and the other hand on the abdomen while the infant remained in a supine position inside the incubator. The intervention started before the painful procedure and continued during and shortly after the procedure. The total duration of the intervention ranged from 7 to 10 minutes. The procedure was performed by the researcher under the supervision of neonatal intensive care unit nurses.

Pain level will be assessed in preterm infants during painful procedures using the Neonatal Infant Pain Scale (NIPS). The NIPS ranges from 0 to 7, where higher scores indicate greater pain intensity. The scale evaluates facial expression, crying, breathing pattern, arm and leg movements, and state of arousal to determine the level of pain.

Respiratory rate will be assessed in preterm infants during painful procedures by measuring the number of breaths per minute using standard neonatal monitoring devices available in the neonatal intensive care unit (NICU). The normal respiratory rate in preterm infants typically ranges from 40 to 60 breaths per minute. Changes in respiratory rate will be used as a physiological indicator of the infant's response to painful stimuli and to evaluate the potential calming effect of the gentle touch technique.

Oxygen saturation (SpO₂) will be continuously monitored in preterm infants during painful procedures using pulse oximetry monitoring devices available in the neonatal intensive care unit (NICU). The normal oxygen saturation range for preterm infants typically ranges between 90% and 95%. Oxygen saturation levels will be used to assess physiological responses to pain and to evaluate the potential stabilizing effect of the gentle touch technique.

Skin color changes will be observed in preterm infants during painful procedures as a clinical indicator of physiological responses to stress and pain. Normal skin color in preterm infants is typically pink, while abnormal findings may include pallor (paleness) or cyanosis (bluish discoloration), which may indicate physiological stress or instability. These observations will help evaluate the infant's response to painful stimuli and the potential soothing effect of the gentle touch technique.
