ABSTRACT
Objective A comparability analysis was performed between the various parameters of the self-developed dry-type blood cell analyzer with the reference instrument (Sysmex XT-1800i).Methods In line with the evaluation program of blood cells issued by ICSH,the detection results,six parameters as HCT,Hb,GRAN (granulocytes),LM (lymphatic and monocytes),WBC and PLT,were compared between the two instruments.Some indexes of the subject instrument such as precision,comparability,outlier points,bias,etc.were analyzed and compared so as to calculate the equation of linear regression and the expected bias intervals.Results The intra and inter CV of the subject instrument about six parameters were respectively less than 5％ and 6％,so it showed that the instrument had good precision.Correlation analysis showed that the classification results of HCT,Hb,GRAN and WBC had a good correlation (r =0.991,0.972,0.986,0.975,P ＜0.01),while that of LM and PLT were slightly lower (r =0.952,0.942,P ＜0.01) ; As to the medical decision level,HCT values were 14％ and 70％,WBC 0.5 × 109/L and 3 ×109/L,and PLT 10 × 109/L,50 × 109/L and 100 × 109/L,and the acceptable bias of these values all fell in the confidence intervals; the values of the rest items were slightly higher than the high value of the confidence interval of expected bias.Conclusions The subject instrument produces the same results in the test of its parameters as the reference instrument Sysmex XT-1800i and therefore the two instruments are comparable.The subject instrument is particularly suitable for field rapid detection.
ABSTRACT
Objective The observation of curative effect and nursing for micro-penetration heating treating wound arms and legs fracture after the operation. Methods 76 cases of the patients suffered from wound arms and legs fracture are divided into 38 cases as the observation group and 38 cases the comparison group at random. The comparison group is treated by normal method only and the observation group is started to be treated by micro-penetration heating treating device for the ray based on the normal method only the second day after operation. Results The observation group is superior to the comparison group in pain situation, wounded infection rate and coalescence time totally (P<0.05). Conclusion The micro-penetration heating treatment can relieve the pain of wound bone fracture to prevent from wounded infection, coalescence to shorten the time of patients' treatment in hospital so that it has a very consequence for it to relieve press from the psychology and finance.
ABSTRACT
Objectives To investigate the effect of bladder function and behavior change training on urinary retention after epidural anesthesia and the method to decrease it. Methods 265 patients receiv-ing operation under epidural anesthesia were divided into two groups, the experimental group (132 cases) and the control group (133 cases). The experimental group was further divided into 3 groups: one to two days of training, 3 to 4 days of training and above 5 days of training preoperation. The experimental group carried out bladder function and behavior change training, but the control group never undertook any train-ing. After operation the data were analyzed. Results The incidence of urinary retention was significantly different between the experimental group and the control group (P<0.01);The time length of the training before operation aorrelated with incidence of urinary retention(P<0.05). Conclusions Bladder function and behavior change training contributed to decrease urinary retention after epidural anesthesia.The training time and incidence of urinary retention showed inverse proportion. This could decrease the opportunity of suffering from urethral catheterization and urinary tract infection.
