The application of blood recovery in adult cardiac valve replacement surgery / 重庆医学

ABSTRACT

Objective To investigate the clinical value of blood recovery in the heart valve replacement surgery of adults. Methods Selected 556 patients accepted cardiac valve replacement surgery from May 2008 to April 2012 in our hospital,and divid-ed into control group(278 cases)and observation group(278 cases)according to the way of intraoperative blood transfusion patients in observation group underwent autologous blood recovery and patients in control group underwent without autologous blood recov-ery,the clinical parameters were observed and statistically analyzed.Results The differences of blood routine after 24 h(such as he-moglobin,hematocrit,platelets,etc.)and blood gas analysis(such as pH,potassium ions,lactic acid,etc.)between two groups were not significantly different,which is statistically insignificant(P >0.05);the postoperative chest drainage of patients in observation group was not significantly different from that of patients in control group,which was statistically insignificant(P >0.05);the a-mount of banked blood in observation group(263.83 ± 19.23)mL was significantly lower than that in control group(615.24 ± 20.34)mL,the difference between two groups was statistically significant(P <0.05).Conclusion In heart valve replacement sur-gery of adults,blood recovery can effectively add blood volume,reduce autologous blood loss,and significantly reduce the amount of banked blood input,which is worthy of promotion.
