ABSTRACT
Natural, biocompatible, and biodegradable composite nanofibers made of Aloe vera extract, pullulan, chitosan, and citric acid were successfully produced via Forcespinning® technology. The addition of Aloe vera extract at different weight percent loadings was investigated. The morphology, thermal properties, physical properties, and water absorption of the nanofibers were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The developed nanofiber membranes exhibited good water absorption capabilities, synergistic antibacterial activity against Escherichia coli, and promoted cell attachment and growth. Its porous and high surface area structure make it a potential candidate for wound dressing applications due to its ability to absorb excessive blood and exudates, as well as provide protection from infection while maintaining good thermal stability.

Resumen OBJETIVO Revisar la experiencia con el traje antichoque no neumático y su integración a los protocolos de atención médica de la paciente con hemorragia obstétrica. MÉTODO Estudio retrospectivo consistente en la búsqueda de artículos en español e inglés que aluden a la hemorragia obstétrica y al traje antichoque no neumático indizados en las bases de datos de PubMed, Cocharne, Embase, Ebsco y Lilacs que reunieran los siguientes requisitos: contenter los términos relacionados: traje antichoque no neumático, non-pneumatic anti-shock garment, hemorragia posparto, postpartum haemorrhage, hemorragia obstétrica, obstetric haemorrhage, choque hipovolémico, hipovolemic shock. CONCLUSIONES La hemorragia obstétrica sigue siendo una de las principales causas de morbilidad y mortalidad materna. La innovación e integración de fármacos y tecnologías, acompañadas de la acumulación de experiencia son decisivas en la resolución de las complicaciones maternas. Está ampliamente demostrada la efectividad y seguridad del traje antichoque no neumático en el tratamiento de la hemorragia obstétrica; sin embargo, hoy día poco se ha utilizado en México.
Abstract OBJECTIVE Conduct a review of the results of the NASG/TANN and its integration into the management of obstetric hemorrhage protocols. Disseminate knowledge of its effectiveness, characteristics, indications, and appropriate use through continuing medical education activities. METHOD Research was conducted on the existence of items that meet the following requirements: Reviewed both English and spanish terms associated with the non-pneumatic anti-shock suit (NASG/TANN). Postpartum Hemorrhage (PPH). Hemorragia postparto. Obstetric hemorrhage (HO). Hemorragia obstétrica. Hypovolemic shock, Choque hipovolémico, whether published in English or Spanish, with reference to human patients. Analysed all the items found in Spanish and English in the following search engines: PubMed, Cocharne, Embase, Ebsco, and Lilacs; and all that reveal a relation between obstetric hemorrhage and the non-pneumatic anti-shock costume. None has been published in a Mexican journal. CONCLUSIONS Obstetric hemorrhage continues to be one of the leading causes of morbidity and mortality. Innovation and integration of drugs and technology, accompanied by the acquisition of proficiency in their use, have been and are fundamental to the management of maternal complications. There is enough scientific evidence to demonstrate the effectiveness and safety of the non-pneumatic anti-shock garment in the management of obstetric hemorrhage; unfortunately, up to the present, little has been implemented in Mexico.
