Adesão às boas práticas obstétricas: construção da assistência qualificada em maternidades-escolas / Adhesión a las buenas prácticas obstétricas: creación de asistencia cualificada en las maternidades escuelas / Adherence to good obstetric practices: building qualified assistance in maternity schools

Objetivo analisar a frequência da realização das boas práticas obstétricas em maternidades-escolas. Método trata-se de estudo descritivo, retrospectivo e documental, de abordagem quantitativa, que analisou 428 prontuários. Resultados 90,91% das parturientes possuíam acompanhante, 81,82% alimentou-se, 82,50% pariu em posição verticalizada e 83,12% teve contato pele a pele. O clampeamento precoce apresentou-se em 28,90%, e 44,17% usaram ocitocina sintética. Foram observados a amniotomia (15,00%), o uso do partograma (37,50%) e aplicação de métodos não farmacológicos para alívio da dor (43,18%). Conclusão nas maternidades-escolas analisadas, a frequência da realização das boas práticas obstétricas ocorria de forma mais criteriosa em alguns casos, mas ainda seria necessária adequação da assistência.

Resultados 90,91% de las mujeres en parto tuvieron acompañante, 81,82% fueron alimentadas, 82,50% tuvieron un parto en posición vertical, y 83,12% tuvieron contacto piel a piel.

Conclusión en las maternidades escuelas analizadas, la frecuencia de las buenas prácticas obstétricas era más juiciosa en algunos casos, pero aun así sería necesario ajustar la atención.

Objective to analyze the frequency of good obstetric practices in maternity schools. Method this is a descriptive, retrospective and documental study of a quantitative approach, which analyzed 428 medical records. Results 90.91% of the women in labor had a companion, 81.82% had been fed, 82.50% had childbirth in vertical position and 83.12% had skin to skin contact. Early clamping was present in 28.90%, and 44.17% used synthetic oxytocin. It was observed the amniotomy (15.00%), the use of the partograph (37.50%) and the application of non-pharmacological methods for pain relief (43.18%). Conclusion in the maternity schools analyzed, the frequency of good obstetric practices occurred more criteriously in some cases, but it would still be necessary to adjust the assistance.

Immunohistochemical response in rats of beta-tricalcium phosphate (TCP) with or without BMP-2 in the production of collagen matrix critical defects.

This study aimed to assess the biological response of BMP-2 (bone morphogenetic protein-2) in supplementation with ß-tricalcium phosphate (TCP) as a carrier in the bone healing of surgical defects in rats' calvaria. A critical-size defect (5mm in diameter) was filled with ß-TCP alone or added with that plus 5mg of BMP-2 at 5, 15, and 30 postoperative days. Histomorphometric and immunohistochemical (osteocalcin, collagen type I, and metalloproteinase-9) analysis was performed to assess the features of bone healing. Histological behavior and collagen type I labeling showed increased formation of the collagen matrix, leading to a higher percentage of newly formed bone and biomaterial for tissue and more total mineralization of pure TCP when compared to the other groups. The supplementation with BMP-2 promoted faster TCP remodeling; however, there was no statistically significant difference for the bone formed in both groups (P>0.05). Collagen-matrix formation and new bone formation reached maximum levels when the defects were filled with pure TCP, even exceeding the levels from BMP-2 supplementation.
