Based on the characteristics of scales, one cannot choose a single one as the most appropriate scale, as this choice will depend on gestational age, type of painful stimulus and the environment in which the infant is inserted. It is suggested the use of multidimensional or one-dimensional scales; however, they must be reliable and validated.

OBJECTIVE: to analyze the total Premature Infant Pain Profile scores of premature infants undergoing arterial puncture during music and 25% glucose interventions, and to assess their association with neonatal and therapeutic variables. METHOD: a randomized clinical trial with 80 premature infants; 24 in the Experimental Group 1 (music), 33 in the Experimental Group 2 (music and 25% glucose), 23 in the Positive Control Group (25% glucose). All premature infants were videotaped and a lullaby was played for ten minutes before puncture in Experimental Groups 1 and 2; 25% glucose administered in Experimental Group 2 and the Positive Control Group two minutes before puncture. RESULTS: 60.0% of premature infants had moderate or maximum pain; pain scores and intervention groups were not statistically significant. Statistically significant variables: Experimental Group 1: head and chest circumference, Apgar scores, corrected gestational age; Experimental Group 2: chest circumference, Apgar scores, oxygen therapy; Positive Control group: birth weight, head circumference. CONCLUSION: neonatal variables are associated with pain in premature infants. Brazilian Registry of Clinical Trials: UTN: U1111-1123-4821.

OBJECTIVE: To analyze studies on methods used to assess pain in newborns. DATA SOURCES: Integrative review study of articles published from 2001 to 2012, carried out in the following databases: Scopus, PubMed, CINAHL, LILACS and Cochrane. The sample consisted of 13 articles with level of evidence 5. DATA SYNTHESIS: 29 pain assessment scales in newborns, including 13 one-dimensional and 16 multidimensional, that assess acute and prolonged pain in preterm and full-term infants were available in scientific publications. CONCLUSION: Based on the characteristics of scales, one cannot choose a single one as the most appropriate scale, as this choice will depend on gestational age, type of painful stimulus and the environment in which the infant is inserted. It is suggested the use of multidimensional or one-dimensional scales; however, they must be reliable and validated.

Objective: to compare the pain response of preterm newborns submitted to arterial puncture who received musical intervention with those who received 25% glucose intervention. Methods: randomized, double-blind clinical trial; the sample consisted of 48 videos of preterm infants of the experimental group (music, n= 6), who listened to music for 10 minutes, and the control group (25% glucose, n=22), who received 25% glucose two minutes before puncture. The pain was evaluated by the Neonatal Facial Coding System at moments: Baseline, Treatment, Painful, Recovery 1 and Recovery 2. Results: there were similarities between groups at the moments Baseline, Recovery 1 and 2. A statistically significant difference was observed at the moment Treatment (p=0.014), Painful (p=0.029) for the control group. Conclusion: 25% glucose differed from music when comparing the pain response in the Treatment and Painful moments. Brazilian Registry of Clinical Trials:Objetivo: comparar resposta de dor de recém-nascidos pré-termo submetidos à punção arterial que receberam intervenção musical com os que receberam intervenção de glicose 25%. Métodos: ensaio clínico randomizado, duplo cego, amostra de 48 vídeos de prematuros dos grupos, Experimental (música, n=26), ouviu música por 10 minutos e; Controle (glicose 25%, n=22), recebeu glicose 25% dois minutos antes da punção. A dor foi avaliada pela Neonatal Facial Coding System nos momentos: Basal, Tratamento, Doloroso, Recuperação 1 e Recuperação 2. Resultados: houve semelhanças entre grupos nos momentos Basal, Recuperação 1 e 2. Constatou-se diferença estatisticamente significante no momento Tratamento (p=0,014), Doloroso (p=0,029) para grupo Controle. Conclusão: glicose 25% diferiu da música ao se comparar a resposta de dor nos momentos Tratamento e Doloroso. Registro Brasileiro de Ensaio Clínico: UTN: U1111-1123-4821.

Objetivo: avaliar a progressão do cateter central de inserção periférica em região hemiclavicular direita, através da veia basílica e cefálica direita, em recém-nascidos. Métodos: pesquisa quase experimental, realizada em unidade neonatal. Amostra de 64 inserções de cateteres, em 58 recém-nascidos. A intervenção consistiu em manobra de elevação, protração e abaixamento do ombro, aplicada após não progressão do cateter, em região hemiclavicular, na punção direta em região cubital, em veia basílica ou cefálica direita. Resultados: das 64 inserções, progrediram sem manobra 28(43,7%); em mais da metade, aplicou-se manobra, obtendo-se 28(77,8%) progressões, sendo que 15(41,7%) progrediram após elevação, 12(57,1%) após protração e 1(11,1%) abaixamento do ombro, destes que progrediram, 21(75%) estavam em posição central. Verificou-se significância estatística (p<0,05) entre progressão com manobra e veia cefálica, progressão sem manobra e veia basílica. Conclusão: a intervenção facilitou progressão do cateter, principalmente por veia cefálica.
