• Status: Not yet recruiting
• Trial end date: 2025-01-01
• Target enrollment: 0
• Participant gender: All

Summary

This study is a parallel group, single blind, randomized controlled trial. Patients with pulmonary hypertension who met the inclusion criteria and planned to undergo elective cardiac surgery under cardiopulmonary bypass from July 1, 2022 to December 1, 2024 in the Department of cardiac surgery of the First Affiliated Hospital of Shandong First Medical University were selected. After removing the aortic blocking forceps, the experimental group immediately injected the test drug (pituitrin 0.04u/ (kg · h)) intravenously, The control group was immediately injected with the corresponding dose of normal saline by intravenous pump. The main outcome was the composite endpoint of all-cause mortality 30 days after operation or common complications after cardiac surgery (stroke, requiring mechanical ventilation for more than 48 hours, deep sternal wound infection, cardiac reoperation, extracorporeal membrane oxygenation, atrial fibrillation or acute renal injury).
