RESUMO
Objective:To investigate the effect of Yinertong antibacterial fluid combined with Yintshu antibacterial gel on puncture wound infection in pleural catheter drainage.Methods:A total of 80 patients who underwent pleural catheter drainage in Gulou Hospital Affiliated to Medical College of Nanjing University from January 2018 to December 2019 were enrolled. They were divided into the control group and the experimental group by random digits table method, with 40 cases each. The control group was given alcohol disinfection and traditional iodophor. The experimental group was given Yinerong antibacterial fluid combined with Yintshu antibacterial gel. The infection of puncture wound, degree of edema, incidence of catheter displacement, colonization rate of catheter pathogens, pain, and nursing satisfaction were observed and compared between the two groups.Results:The wound infection rate was 15% (6/40) in the control group, and 0(0/40) in the experimental group, the difference was statistically significant ( χ2=4.50, P<0.05). There was no significant difference in colonization rate of catheter pathogens between the two groups ( P>0.05). There were 28, 6, 4 and 2 cases of no edema, mild, moderate and severe edema in the control group and 38, 1, 1 and 0 cases in the experimental group, the difference was statistically significant ( Z=8.19, P<0.05). There was no significant difference in the scores of Visual Analogue Scale (VAS) of immediate pain of puncture between the two groups ( P>0.05). The score of VAS after 24 hours of puncture and at the time of extubation was (3.10 ± 1.34), (1.50 ± 1.36) points in the experimental group, and (3.83 ± 1.28), (2.38 ± 1.28) points in the control group, the differences were statistically significant ( t=2.48, 2.97, both P<0.05). The satisfaction rate after discharge was 97.5% (39/40) in the experimental group, and 80.0% (32/40) in the control group, the difference was statistically significant ( χ2=8.31, P<0.05). Conclusions:The combined application of Yinertong antibacterial fluid and Yintshu antibacterial gel can significantly reduce the wound infection rate of pleural catheter drainage, reduce wound edema and pain, and improve patients′ satisfaction with nursing work, which is worthy of popularization and application.
RESUMO
Purpose To investigate the value of low dose CT combined with iterative model reconstruction (IMR) technique for evaluation of both breast lesion and pulmonary metastasis in patients with breast cancer,and compare the effects of IMR,hybrid iterative reconstruction (HIR) and filtered back projection (FBP) techniques on image quality.Materials and Methods Twenty-one patients with solitary tumor confirmed by mammography and/or ultrasonography at Navy General Hospital from January to May in 2016 were enrolled,and the related breast imaging reporting and data system reached to level 4 and above.All patients underwent dynamic contrast-enhanced CT with different tube current for breast (scanning 6 times within 6 minutes) and chest scans;the conventional tube current (61 mAs) was used at the 2 minutes phase after injection,and the low tube current (10 mAs) was used at the other 5 phases.CT images were reconstructed with FBP,HIR and IMR techniques,respectively.The images of breast lesions and chest in 2 minutes scans were evaluated objectively and subjectively.Results The mean effective radiation dose was (2.15 ± 0.39) mSv.The images of 3 reconstruction techniques at the 2 minutes phase were compared,and the IMR images showed the lowest image noise and the optimal contrast to noise ratio (P＜0.05).The images quality of 3 kinds of reconstruction techniques was acceptable,of which IMR was better than HIR and FBP (P＜0.05).Conclusion Low dose CT scan combined with IMR technique can remain low radiation with dose of 2 mSv,while maintaining good image quality,which can be used for preoperative evaluation of both breast lesion and pulmonary metastasis in patients with breast cancer.
