Clinical study of improved painless management with fiberoptic bronchoscopy

Objective To explore the effect and safety of diazepam plus tramadol intravenous combined lidocaine surface anesthesia in patients under going painless fiberoptic bronchoscopy. Methods 200 patients were separated randomly into two groups:lidocaine surface anaesthesia group (group A)and lidocaine surface anaesthesia combined diazepam plus tramadol intravenous group (group B). Patients' heart rate (HR), breathe rate, blood pressure (BP) and oxygen saturation (SpO2) before and during the operation were observed. Their cough, pain, feeble, dizziness, suffoduring the operation were counted. Then all patients were asked about the operation experience. Results Compared to the data, the mean HR and BP before and during the operation be showed significant increased in group A ( P ＜0. 001) and not in group B ( P ＞0.05). Mean SpO2 during the operation decreased significantly in group A, only 51. 7% of the patients agreed to accept the next one,and no significant difference showed in group B. There were more bad memory after the operation in group A. Nevertheless, 90% of the patients in group B were willing to accept another operation ( P ＜ 0. 001). Conclusions Lidocaine surface anaesthesia plus tramadol and diazepam in painless fiberoptic bronchoscopy is safe and effective. Key words: Bronchoscopy ; Painless;  Lidocaine;  Tramadol and diazepam
