Correlation Between he Ratio Pipp-R and Nips and Inter-Rater Reliability to Evaluate Pain During the Procedure Suction in Newborn Premature
Abstract Objectives:To verify the Correlation between the Neonatal Infant Pain Scale (NIPS) and Premature Infant Pain Profile – Revised (PIPP-R), the internal consistency of each scale, and assess the reliability between evaluators in the assessment of pain during the aspiration procedure in premature newborns. Methods: an observational, prospective study. Participated in the study, 50 infants who met the following criteria for inclusion: Newborn (NB) preterm (GA> 26 weeks and <36 weeks and five days) with low birth weight (<2500 g), hemodynamically stable, with minimal sedation or without sedation or mechanical ventilation in CPAP or catheter nose of O2 or the air environment that needed to perform the procedure of vacuum in the period of hospitalization. The evaluation of the newborns occurred during three different aspiration procedures; aspiration 1 (no intervention), aspiration 2 (use of gentle touch), and aspiration 3 (use of sucrose). They have applied two evaluation instruments, NIPS and PIPP-R. that Cronbach's alpha determined the internal consistency, reliability between evaluators by the coefficient of Correlation intraclass, validity competitor by Spearman test. Results: Internal Consistency was high for NIPS (r= 0.824) and moderate for PIPP-R (0.655). Reliability between raters was high respectively in the three conditions 0.991; 0.987; 0.993 on the NIPS scale and 0.997; 0.986; 0.977 on the PIPP-R scale. One observed concurrent validity Only in the first aspiration. Conclusion: the NIPS seems to have a better utility clinic than PIPP-R; however, the two scales showed good reliability among the evaluators, and internal consistency, being a good choice for evaluation of pain during the procedure of aspiration.
