ABSTRACT
Objective To predict the length of peripherally inserted central venous catheters(PICC) with electronic chest radiograph scale measurement techniques, and observe its clinical effect. Methods A total of 185 breast cancer patients from October 2012 to December 2013 who were treated by PICC combined with MST guided by ultrasonic technology were as control group. A total of 192 breast cancer patients from January to November 2014 were as observation group. Control group adopted from the puncture point to right sternoclavicular joints impreaaion nip down again to the third floor of PICC in vitro measurement method. Observation group used to right sternoclavicular joints from the puncture point plus right sternoclavicular joints to subcarinal 1 vertebral body length, right sternoclavicular joints to subcarinal 1 vertebral body length measurement by electronic chest radiograph scale technology directly measured from the electronic chest radiographs. The accuracy rates and complications between the two measurement methods were compared. Results The accuracy rate in observation group was 97.92%(188/192), which was higher than that in control group (68.11%,126/185 ),and there was significant differencek,χ2=60.15, P<0.01. The complication rate in observation group was 6.77%(13/192), which was lower than that in control group (20.54%, 38/185) ,and there was significant difference,χ2=9.58, P<0.01. Conclusions The electronic chest radiograph scale measurement techniques could effectively improve the accuracy of PICC catheter placed, improve the quality of venipuncture, decrease the complications .
ABSTRACT
Objective To discuss effect of urine specimen placed length on red blood cells detection. Methods Selected 400 cases of blood in the urine specimen from January 2012 to January 2013 as research objects who were analyzed by the current physical composition analyzer urine UF-100. Effect of different placed time on source of hematuria differ-ential sensitivity, RBC and the parameters results were compared. Results Sensitivity identification of the source of hematuria of specimen placed within 15 min, 2 hours, 4 hours were 94.97%(189/199),88.94%(177/199),83.42%(166/199). RBC,RBC-p70Fsc,RBC-Fsc-Dw and Non-lysed RBC%of variants placed 2 h and 4 h showed significant differences compared with placed placed 15 min(P<0.05); RBC-p70Fsc and Non-lysed RBC% of mixed type placed 2 h and 4 h showed significant difference compared with placed 15 min(P<0.05); RBC-Fsc-Dw of isotypy placed 2 h and 4 h showed significant difference compared with placed 15 min(P<0.05). Conclusion When evaluate the RBC in the urine,if possible,the best use of fresh urine and finish within 2 hours for detecting to avoid misdiagnose.
