The nursing points included planning the bed unit well and selecting a cultivation box with a large spatial area to maintain the stable body temperature of the twins,ensuring proper identification through careful labeling,using appropriate props for position management to reduce the incidence of head deformities,arranging the position of the non-operative twin according to examination requirements,implementing prevention measures to avoid infection related to the conjoined anatomy,evaluating the physiological status of the twins and providing individualized care,accurately measuring the weight of the conjoined twins to provide a basis for nutritional and medication strategies. The separation surgery was successfully performed on day 41 of hospitalization,and newborn A was discharged smoothly on the 8th day after surgery,and newborn B was discharged from the hospital on the 41st day after surgery.
