医生督导留取和送检痰细菌培养标本结果分析

目的探讨目前医院痰培养标本留取和送检过程中存在的问题。方法将2011年2月～2012年2月收住安阳地区医院呼吸与危重症医学科的152例肺炎患者随机分为2组。医生督导组80例,采用医生督导下留取及送检痰细菌培养标本;对照组72例无医生督导由护士自行留取及送检标本。通过观察痰细菌培养结果阳性率来评价医生督导正确留取及送检痰标本的重要意义。结果 152例患者中,医生督导组送检80例标本,41例培养阳性,阳性率51.25%;对照组送检72例标本,23例培养阳性,阳性率31.94%。两组比较,?2=5.794,医生督导组较对照组差异显著,具有统计学意义(P<0.05)。结论 医生督导下留取及送检痰培养标本能大大提高痰培养阳性率。

Objective To explore the problems of preserving and submitting sputum samples for bacterial cultivation at present in hospital. Methods 152 cases of pneumonia which Hospitalized in the department of breath and critical medicine of Anyang district hospital from February 2011 to February 2012 were randomly divided into two groups.There are 80 patients in the first group, whose sputum samples were preserved and submitted by doctor＇s direction;In another group, 72 cases＇ sputum samples were preserved and submitted by nurse,no doctor＇ direction. To evaluate the important significance of preserving and submitting sputum samples by doctor＇s direction though observing the difference of positive rate. Results In the doctor＇S direction group,Send 80 samples of sputum, 41 cases were positive,and the positive rate is 51.25%; in the other group, send 72 cases, 23 cases were positive,and the positive rate is 31.94%. Two groups of comparisons, through the Chi-square test, x2=5.794 （P 〈 0.05）, there is a remarkable differences between the doctor＇s direction group and the control group. Conclusion Though doctor＇S direction in preserving and submitting the samples of sputum,can improve the positive rate of bacterial cultivation.
