Abstract:
Aim To optimize the traditional method of right catheterization in rats and establish a rapid , stable and reliable method of the right heart catheter guided intubation to measure pulmonary artery pressure. Methods Nighty male wistar rats were used to optimize the method of detection of pulmonary arte-rial pressure. Three catheter namely PE50, PU I, and PU II were used for choosing the best intubation. The new technology of right catheterization was established and used for the research of pulmonary arterial hypertension. Results The PU I catheter was obviously better than PE50 and PU II catheter in the success rate and measurement time ( P <0. 05 ) . The method of right heart catheter guided intubation was significantly superior to the traditional right heart direct intubation (P<0. 05 or P<0. 01). After improving the right catheterization, the detection of hemo-dynamic indexes in PAH-model rat was successful with regular pressure curve and reliable experimental data. Conclusions The right heart catheter guided intubation method has a high suc-cess rate and it can detect the pulmonary artery pressure quick-ly, easily, and can help other researchers to complete experi-ment as efficiently as possible.
