Application and nursing of ANH in combination with autologous blood transfusion in cesarean section delivery

Abstract

Objective To summarize the nursing cooperation in 28 cases of placenta praevia or dangerous cesarean section delivery in which acute normovolemic hemodilution (ANH) in combination with autologous blood transfusion were applied. Methods Before the surgery, autologous blood were collected from 28 cases with smooth anesthesia of ASA class Ⅰ-Ⅱ parturients post general anesthesia, accompanying rapid intravenous infusion of the equivalent colloid solution.The vital sighs and fetal heart of parturients were comprehensive monitored during the collection procedure. When the blood loss reached to 400-600 ml or the hemoglobin (Hb) were below 80 g/L during the late phase of surgery, autologous blood was transfused to parturients. Results All 28 cases safely wentthrough the operative period with the mean operation time (69.00±18.81) min, mean blood loss (988.00±382.65) ml and mean autologous blood transfusion (387.00±122.07) ml, respectively. Meanwhile, there were no adverse reactions of parturients during the process of collection and transfusion of autologous blood. Furthermore, the mean 1, 5 min Apgar score of newborn children ranged from 7 to 10. Conclusions ANH in combination with autologous blood transfusion, serving as an effective measure for blood conservation, plays a important role in dealing with postpartum hemorrhage and was not harmful to parturients or fetuses.ANH in combination with autologous blood transfusion, as a safe and efficient blood transfusion mode, attenuated the current shortage of blood for clinical use to a great extent.
