The primary objective was to evaluate the effectiveness of breastfeeding or supplemental breast milk in reducing procedural pain in neonates. The secondary objective was to conduct subgroup analyses based on the type of control intervention, gestational age and the amount of supplemental breast milk given.
We searched CENTRAL, MEDLINE, Embase, CINAHL and trial registries (ICTRP, ISRCTN and
clinicaltrials.gov) in August 2022; searches were limited from 2011 forwards. We checked the reference lists of included studies and relevant systematic reviews.
We assessed the methodological quality of the trials using the information provided in the studies and by personal communication with the authors. We extracted data on relevant outcomes, estimated the effect size and reported this as a mean difference (MD). We used the GRADE approach to assess the certainty of evidence.
Of the 66 included studies, 36 evaluated breastfeeding, 29 evaluated supplemental breast milk and one study compared them against each other. The procedures conducted in the studies were: heel lance (39), venipuncture (11), intramuscular vaccination (nine), eye examination for retinopathy of prematurity (four), suctioning (four) and adhesive tape removal as procedure (one). We noted marked heterogeneity in the control interventions and pain assessment measures amongst the studies. Since many studies included multiple arms with breastfeeding/supplemental breast milk as the main comparator, we were not able to synthesise all interventions together. Individual interventions are compared to breastfeeding/supplemental breast milk and reported. The numbers of studies/participants presented with the findings are not taken from pooled analyses (as is usual in Cochrane Reviews), but are the overall totals in each comparison.
El uso y la enseanza del modelo PICO estn muy extendidos en el mbito de la atencin sanitaria basada en la evidencia para formular preguntas y estrategias de bsqueda y para caracterizar estudios o metanlisis clnicos. PICO son las siglas en ingls de cuatro posibles componentes de una pregunta de investigacin: paciente, poblacin o problema; intervencin; comparacin; desenlace (outcome).
