Efficacy of Skin-to-Skin Care versus Swaddling for Pain Control Associated with Vitamin K Administration in Full-Term Neonates: A Randomized Controlled Trial.

Abstract

The objective of the study was to assess the efficacy of immediate skin-to-skin care (SSC) versus swaddling in pain response to intramuscular injection of vitamin K at 30 min of birth in neonates. Healthy full-term newborns were enrolled immediately after normal vaginal delivery and randomized in two groups, SSC and swaddling. Neonatal Infant Pain Scale (NIPS) was measured before, immediately after and at 2 min after the injection. Total 100 newborns were enrolled in the study (50 in each group). The mean (SD) birth weight of newborns in the SSC and swaddling group was 2668 (256) and 2730 (348) g, respectively. NIPS was comparable between the SSC and swaddling at before [1.78 (0.58) vs. 1.96 (0.83), p = 0.21], and immediately after the injection [4.82 (0.72) vs. 5.08 (0.75), p = 0.08]. NIPS at 2 min after the injection was significantly low in the SSC group compared to the swaddling group [1.38 (0.70) vs. 2.88 (1.00), p < 0.001]. At 2 min after injection, the NIPS score was significantly lower than baseline in the SSC group (p = 0.002), while it was significantly higher in the swaddling group (p < 0.001). A significantly higher proportion of newborns had a NIPS score of more than three at 2 min after injection in the swaddling group as compared to the SSC group (22% vs. 2%, p < 0.001). Immediate SSC was more efficacious as compared to swaddling as a pain control intervention while giving vitamin K injection. The trial is registered with the Clinical Trial Registry of India with Registration number: CTRI/2020/01/022984.
