A comparative study of crystalloid solution mixed with colloidal solutions and pure crystal solution as extracorporeal circulation priming solution in adult simple heart valve replacement with cardiopulmonary bypass / 中国医师杂志

ABSTRACT

Objective To investigate physiological changes in peri extracorporeal circulation period of patients who underwent cardiac valve replacement surgeries with crystalloid solution mixed with colloidal solutions and pure crystal solution as extracorporeal circulation priming solution, and explore the clinical value and practicability of crystalloid solution as the sole extracorporeal circulation priming solution.Methods A retrospective analysis was performed in 130 patients who underwent cardiac valve replacement surgeries.Pure lactated Ringer's solution liquid and Lactated Ringer's solution mixed with Voluven as the extracorporeal circulation priming solution were used.We respectively compared hematocrit at different time points, postoperative blood routine, liver and kidney function, blood coagulation index, duration of intensive care and trachea cannula in two groups.Results There were no significant differences in ages, preoperative blood routine, kidney function, blood coagulation function, duration of operation, clamping time, bypass time, intensive care, postoperative blood routine, kidney function, blood coagulation function and hematocrit at different time points in two groups (P ＞0.05).However, the hospital day of group which used crystalloid solution as extracorporeal circulation priming solution was significant shorter compared to group which used lactated Ringer's solution mixed with Voluven (P ＜ 0.05).Alanine aminotransferase of group which used crystalloid solution as extracorporeal circulation priming solution was significant higher compared to group which used lactated Ringer's solution mixed with Voluven (P ＜0.01).Conclusions Crystalloid solution as extracorporeal circulation priming solution is safe and economy in cardiopulmonary bypass.Pure crystalloid solution as the sole extracorporeal circulation priming solution can be safely used on patients (New York Heart Association class Ⅱ-Ⅲ) who have normal liver and kidney function before the operation of adult heart valve replacement with cardiopulmonary bypass.
