Abstract:
Objective To investigate the influence factors on length of ICU stay in cardiac rupture patients after surgical repair.Methods A retrospective study was conducted and enrolled survived cardiac rupture patients admitted to ICU of Wuxi People's Hospital from January 2009 to January 2017.Clinical data of patients were recorded including age,causes,complications,blood transfusion,duration of mechanical ventilation,duration of vasoactive agent employment,and length of ICU stay.At the same time,the laboratory findings were documented including hemoglobin(Hb),hematocrit (Hot),serum creatinine,blood lactic acid and creatine kinase muscle b(CK-MB).Patients were divided into two groups according to length of ICU stay(A group ＞3 d,B group ≤ 3 d).Data were analyzed using SPSS20.0 and MedCalc software.Pearson correlation test and ROC curve were taken to analyze the predicting factors for the prognosis.Results Twenty-two patients were referred to ICU after operation and survived.The length of ICU stay varied from 2 to 12 d.The statistical analysis showed the levels of Hb and Hct in group A were lower than those in group B (P＜0.05);the levels of CK-MB and lactic acid in group A were higher than those in group B (P＜0.05);and larger volume of blood transfusion (P=0.002),higher complications (P=0.024),longer duration of mechanical ventilation (P=0.001) and longer duration of vasopressor application (P=0.003) were found in group A.Pearson correlation test showed Hb and Hct had negative correlation with duration of mechanical ventilation,duration of vasoactive agent application and length of ICU stay (P＜0.05),whereas the CK-MB and lactic acid had positive correlation with duration of mechanical ventilation,duration of vasoactive agent employment and length of ICU stay (P＜0.05).ROC curve showed lactic acid,Hct,and CK-MB all had significance in prediction of prolonged ICU stay,and there were no statistically significant differences in areas under the curve(AUC) among these three biomarkers (P＞0.05).With the employment of ROC curve,the optimal cut-off points of three biomarkers for clinical diagnosis were lactic acid ≥ 3.4 mmol/L,Hct ≤ 39％,CK-MB ≥ 58 U/L.Conclusion Hb,Hct,lactic acid,CK-MB,blood transfusion,complications,duration of mechanical ventilation,duration of vasoactive agent employment were factors influencing on length of ICU stay in cardiac rupture patients after operations.The levels of lactic acid,Hct,and CK-MB had significance in prediction of prolonged ICU stay.
