OBJECTIVE: To design the dosage regimen of aminophylline using reported pharmacokinetic parameters (mean group value). METHODS: The calculation of oral maintain dose, the infusion rate of intravenous drip maintain dose and the loading dose of intravenous drip were introduced. RESULTS: Different dose were required for different pathophysiological conditions insteading of aminophylline 200 mg three times a day (p.o.) for every patient. CONCLUSION: It is recommended that all hospitals which are unable to determine plasma concentration should design dosage regime of aminophylline using pharmacokinetic parameters.

OBJECTIVE: To explore the feasibility and safety of analgesia fiber bronchoscopy assisted by midazolam and fentanyl citrate. METHODS: A contrastive study was performed between analgesia bronchoscopy group(group A,n=58) and conventional bronchoscopy group (group B,n=57). RESULTS: 100% of patients in group A completed the examinations safely; 3.5% of patients in group B had to stop the check due to excessive pain. Group A was better than group B in the following aspects: better anaesthetic effects that made physicians perform better targeted examination(P

0.05),respectively.CONCLUSION:Intravenous drip combined with oral administration of Amoxicillin/Clavulanate Potassium can replace intravenous dip of Amoxicillin/Clavulanate Potassium bid.For those ?-Lactams drugs with short t1/2,the unreasonable intravenous drip of which qd can be replaced by the intravenous drip combined with N-time oral administration or with N-time intramuscular injection.
