Upper surgical field for cesarean section intervention with neonatal transfer

UndeterminedES3049869B2Upper abdominal surgeryFull Term Neonate
The upper surgical field for cesarean section intervention with neonatal transfer aims to eliminate the current limitations of the "humanized cesarean" by creating a circuit for direct transfer of the newborn to its mother within the surgical field and without altering asepsis. This internal communication is achieved by means of a sterile main drape with a fenestration in its caudal portion that continues perpendicularly with a transfer module located over the maternal thorax, a non-sterile area, with an integrated closure system. Additionally, the main drape has a secondary drape designed to seal the fenestration. This surgical field allows for maintaining sterility during neonatal transfer, optimizes delayed clamping of the umbilical cord, ensures the preservation of heat and continuous visualization of the newborn, achieves immediate skin-to-skin contact, and increases maternal participation in welcoming the newborn.
