Introduction To investigate the perioperative anesthesia management of percutaneous pulmonary valve implantation (PPVI). Methods Clinical data of 6 patients undergoing PPVI operation were retrospectively analyzed in children's heart center of Henan Provincial People's Hospital from December 2017 to January 2020, including 3 males and 3 females with mean age (16.3±5.4) years,weight 41.2±12.3Kg. All patients received endotracheal intubation under general anesthesia. Systolic blood pressure (SBP) and diastolic blood pressure (DBP),heart rate(HR),central venous pressure(CVP),pulse oxygen saturation(SPO2) were recorded before anesthesia induction (T1),after anesthesia induction (T2),before surgery (T3),before percutaneous pulmonary valve implantation (T4),during percutaneous pulmonary valve implantation (T5),after percutaneous pulmonary valve implantation (T6) and out of the operating room (T7). Right ventricular systolic (SRVP) and right ventricular diastolic (DRVP), pulmonary artery systolic (SPAP) and diastolic (DPAP) were recorded before T4 and after T6. Intraoperative complications were recorded. The time of tracheal catheter removal was recorded. The time of stay in ICU and the time of discharge was recorded. Results Compared with T1,T2,T3,T4,T6,T7,SBP,DBP,HR and SPO2 was significantly reduced at T5 (P Discussion Tracheal intubation general anesthesia is suitable for percutaneous PPVI surgery. Hemodynamic monitoring should be strengthened during pulmonary valve implantation to maintain circulatory stability.
