ABSTRACT
Objective:To explore the application and nursing of chest radiograph combined with body surface measurement in measuring the length of PICC intubation in tumor patients.Methods:Totally 60 cases of malignant tumor patients in our hospital from March 2019 to January 2020 were selected and randomly divided into two groups by the method of random number table. 30 cases in the control group were given PICC catheterization by conventional body surface measurement; 30 cases in the observation group were given PICC catheterization combined with chest imaging data. After the intervention, the precise position of PICC catheter, indwelling time, complications, nursing satisfaction rate and quality of life were compared between the two groups.Results:After the intervention, the accurate placement rate, adjustment ratio and indwelling time of the observation group were 100.00% (30/30), 0, (146.35±21.74) d, which were significantly better than 83.33% (25/30), 16.67% (5/30) and (118.44±17.36) d of the control group, the difference was statistically significant ( tvalue was 5.495, χ 2values were 4.286, 5.455, all P<0.05); after intervention the complication rate, nursing satisfaction rate, and quality of life score in the observation group were 3.33% (1/30), 99.67% (29/30), (91.35±8.58) points, which were significantly better than the control group's 26.67% (8/30), 80.00% (24/30), (83.57±7.36) points, the difference was statistically significant ( χ 2values were 6.405, 4.043, tvalue was 3.775, P<0.05 or 0.01). Conclusion:Chest imaging data combined with body surface measurement methods combined with comprehensive care can significantly improve the accuracy of PICC catheter placement in cancer patients, reduce catheter adjustment and the deviation of actual length from the ideal length, extend the indwelling time, reduce complications, and improve patients Care satisfaction rate and quality of life.
ABSTRACT
Objective To design pedometer shoes through wireless transmission step calculation.Methods The transmitting terminals in the soles acquired the pressure signals,and then the signals were transmitted to the SCM after conversion,amplification and comparison.AT89S52 SCM was used for step calculation and then the results were sent to the receiver through nRF905.Results The receiver had three modes,such as the step-calculation mode with the time and step calculation result displayed,the running mode with the distance displayed and the function of stopwatch,and the prompt mode with the distance and consumed power displayed.Conclusion The wireless embedded pedometer shoes are multifunctional,easy to operate and reliable.
