Investigating the effect of vibration on the reduction of blood sampling pain from heel (lance) in preterm neonates: a clinical trial study.
Abstract
Introduction Preterm neonates are exposed to very painful procedures during hospitalization, which non-pharmacological and pharmacological methods are used to reduce pain. Vibra- tion stimulations is performed using a vibrator to relieve pain in adults and children, but little research has been done on the sedative effect of vibration in neonates. This study was aimed to investigate the effect of vibration on pain reduction caused by blood-sampling from heel (lance) in preterm neonates hospitalized to the neonatal intensive care unit. Material and Methods This study is a randomized controlled clinical trial study in which 70 neonates with fetal age1 of 30-36 weeks were hospitalized in Ali Ibn Abi Talib Hospital (Zahedan in 1398) and blood sampling from the heel was carried out for them. The samples were selected by random blocks method and placed in two groups of intervention and con- trol. In the intervention group used from vibration by Norco Mini Vibrator massage device (North Coast Med- ical Inc, NC70209, Gilroy, California), which was placed on the middle muscle and next to the leg below knee 30 seconds before the blood sampling from the heel and the test was performed for 30 seconds.. The data collection tools included a demographic information questionnaire and a pain intensity tool of term and preterm neonates (NIPS). Data was analyzed using descriptive and inferen- tial statistics methods and SPSS 20 software. Results Of the 70 neonates who participated in this study, 62.9% were male (44) and 37.1% were female (26) and 69.4% of them had fetal age of 32-35 weeks. The mean painscore was 2.48 in the intervention group and 4.37 in the control group. There was a statistically significant differ- ence between the mean score of pain intensity in the con- trol and intervention groups (p = 001). Conclusion The use of vibration is an effective technique in reducing neonatal pain, which should be considered by nurses and health centers staff compared to routine cares (non-nutri- tive sucking, oral sucrose, hug care) when performing in- vasive procedures on neonates.
