Abstract
Objective

To investigate the effect of lanolin on nipple pain and trauma in breastfeeding after application of a health education.

Method

Randomized controlled clinical trial, with two arms, open, with 66 participants during prenatal care in the primary health care network in Goiania – Goias, Brazil. Participants were randomized (1:1) using computer generated numbers in both experimental group (EG) and control group (CG). The EG received lanolin and health education on breastfeeding at two different times with clinical demonstration using cloth didactic breast and illustrative album as the intervention, while the CG received standard health education. Health education was carried out by the same researchers in both groups. Measurement of pain, nipple trauma, and breastfeeding technique occurred on postpartum day eight. The analysis included descriptive statistics and inferential analysis by means chi-square or Fisher test, and Student's t-test, significance level set at 0.05.

Results

A majority of the participants experienced no nipple trauma (59.1%) in both groups, and 60.6% of women experienced pain. In both groups, women showed favorable breastfeeding behaviors, except in the condition of the breasts. There were no significant differences between groups in pain prevention (p=0.61), nipple lesions (p=0.21), and breastfeeding technique (p>0.05).

Conclusion

It is not clear whether the intervention, lanolin combined with health education, has a positive effect on the prevention of nipple pain and trauma. Further research is needed to elucidate this question.

Resumen
Objetivo

Investigar el efecto de la lanolina sobre el dolor y el traumatismo de los pezones en la lactancia después de la aplicación de educación para la salud.

Método

Ensayo clínico controlado aleatorizado, con 2 brazos, sin cegamiento, con 66 participantes durante la atención prenatal en la red básica de salud en Goiânia-Goiás, Brasil. Las participantes fueron aleatorizadas (1:1) utilizando números generados por computadora en el grupo experimental (EG) y en el grupo de control (CG). El EG recibió lanolina y educación para la salud sobre lactancia materna en 2 momentos diferentes, con demostración clínica y álbum ilustrativo como intervención, mientras que el CG recibió educación para la salud estándar. La educación para la salud fue realizada por los mismos investigadores en ambos grupos. El dolor, la lesión del pezón y la lactancia se midieron en el octavo día posparto. El análisis incluyó estadística descriptiva y análisis inferencial mediante la prueba de Chi-cuadrado o Fisher y la prueba de la t de Student, con un nivel de significación de 0,05.

Resultados

La mayoría de las participantes no experimentaron lesiones en el pezón (59,1%) en ambos grupos, y el 60,6% de las mujeres experimentaron dolor. En ambos grupos, las mujeres mostraron comportamientos favorables a la lactancia materna, excepto en la condición de los senos. No hubo diferencias significativas entre los grupos en la prevención del dolor (p=0,61), lesiones de los pezones (p=0,21) y la técnica de lactancia (p>0,05).

Conclusión

No está claro si la intervención de lanolina combinada con educación para la salud, tiene un efecto positivo en la prevención del dolor y el traumatismo en los pezones. Se necesitan más investigaciones para dilucidar esta cuestión.
