Objective The intracardiac electrocardiogram (ecg) positioning technology in the clinical appli -cation of PICC catheter tip to locate effect were discussed .Methods 115 cases of our department in October 2013-2014 December PICC placement of patients admitted to the study .All patients completed according to uniform pro -cedures catheter, and the use of intracardiac electrocardiogram positioning technology in the catheterization process PICC catheter tip positioning, again catheter positioning X -ray film.Results Intracardiac electrocardiogram PICC tip into the superior vena cava sensitivity of 93.03%, and the situation is a total of seven cases no P wave changes , the rest of the patient P or T wave changes .X -ray showed 108 cases of catheter tip is located on the within the vena cava, and two cases in the subclavian vein (intravenously to two cases of circular motion , resulting in a circular mo-tion intravenous catheter insufficient length , which does not reach the superior vena cava ), and two cases in the inter-nal jugular vein, three cases in the brachial vein .Conclusion PICC catheter tip positioning taking intracardiac elec -trocardiogram positioning technology , with high sensitivity and specificity , which can be clinical application .

Objective To compare the impact on the results tested with arterial blood gas analysis and peripheral blood with glucose meter for critical patients in ICU in different temperature states. Methods The samples of venous biochemical test, blood arterial blood gas analysis and peripheral blood of 196 cases of critical patients in ICU were collected synchronously, and measure the D-value, correlation and bias adjustment factor of glucose blood tested with a synchronous fasting blood glucose test and venous/biochemical analyzer in different temperature states and different blood glucose groups, and the results of blood glucose test were analyzed. Results In normal temperature state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 3.31%(5/151), while the pairwise comparison showed there was both statistical signifcance between hypoglycemia group and target group (χ2=38.469), hyperglycemia group and target group (χ2=15.504) when choosing a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). In high temperatures state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 0. There was both statistical significance between hypoglycemia group and target group (χ2=18.187), hypoglycemia group and hyperglycemia group (χ2=12.857) when choose a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). Conclusions In high temperatures state, a synchronous fasting blood glucose test can not reflect the true value of blood glucose for critical patients.
