ABSTRACT
Objective: To evaluate the action of 2% lidocaine on the culture results of bronchial fluid in patients suspected of having lower respiratory tract infections
Study Design: Cross-sectional analytical study
Place and Duration of Study: Shahid Sadoughi Hospital, Yazd, Iran, from November 2014 to November 2015
Methodology: Patients suspected of lower respiratory tract infections referred to bronchoscopy unit of the Hospital were included. Those with incomplete questionnaire and bronchoscopy contraindication were excluded. Bronchial fluid was aspirated before and after local application of 2% lidocaine and cultured, according to the suspected clinical diagnosis. Finally, statistical analysis was performed using SPSS software, version 17.0. For statistical comparisons, McNemar's test was used. Level of significance was kept at p <0.05
Results: The mean age of the study population was 51.83 +/- 15.93 with a range of 25 - 80 years. Out of 130 patients, 60 patients had positive culture results. Nineteen [31.7%] cases had positive culture for tuberculosis and 41 [63.3%] cases had positive results for other bacteria before intervention that did not change after using 2% lidocaine [p=1]. In 70 [53.84%] cases, results were negative before and after use of 2% lidocaine
Conclusion: No significant difference was found between culture results before and after the use of lidocaine. Therefore, lidocaine can be used during bronchoscopy to increase patient tolerance
ABSTRACT
Objective: Although computer technologies are now widely used in medicine, little is known about its use among medical students in Iran
The aim of this study was to determine the competence and access to computer and internet among the medical students
Methods: In this descriptive study, medical students of Shahid Sadoughi University of Medical Science, Yazd, Iran from the fifth years were asked to answer a questionnaire during a time-tabled lecture slot
The chi-square test was used to compare the frequency of computer and internet use between the two genders, and the level of statistical significance for all test was set at 0.05
Results: All the students have a personal computer and internet access
There were no statistically significant differences between men and women for the computer and internet access, use wireless device to access internet, having laptop and e-mail address and the difficulties encountered using internet
The main reason for less utilization of internet was slow speed of data transfer
Conclusions: Because of the wide range of computer skills and internet information among medical students in our institution, a single computer and internet course for all students would not be useful nor would it be accepted
