Effect of Palmar Grasp Reflex Stimulation on Physiological Parameters and Crying Time During Neonatal Bath: A Randomized Controlled Trial.

Objective: This study aimed to determine the effect of palmar grasp reflex stimulation during a neonatal bath on the physiological parameters and crying time of the newborn.

Design, Setting, And Participants: This study was designed as a parallel randomized clinical trial. Parents fully understood the study procedure at the Neonatal Intensive Care Unit in Turkey ( = 82). Both written and verbal consent was obtained from the parents. Newborns who were ineligible for tub bathing were excluded from the study. The babies in the control group were given baths according to the tub bathing standards. Babies in the experimental group were given palmar grasp reflex stimulation during the baths. The variables examined included body temperature, respiratory rate, pulse, oxygen saturation levels, and crying time. In all analyses, 0.05 was accepted as statistically significant.

Results: The heart rate of the experimental group was 5.2 beats per minute slower than the control group (χ2 = 12.272; 0.001). The respiratory rate of the experimental group was 1.3 lower per minute compared to the control group (χ2 = 43.219; 0.001). In addition, the oxygen saturation level (%) of the experimental group was 0.4 higher than the control group (χ2 = 5.793; 0.016). Crying time was higher in the control group during bathing ( 0.001).

Conclusion: The results showed that the palmar grasp reflex in newborn bathing helps to maintain the stability of physiological parameters and shortens the crying time of babies. Palmar grasp reflex stimulation is recommended in interventions that may cause stress.
