Efficacy and Safety of High-Flow Nasal Cannula Versus Noninvasive Ventilation for Pulmonary Arterial Hypertension-Associated Acute Respiratory Failure

Sponsor: The First People's Hospital of Neijiang

View on ClinicalTrials.gov

Summary

This is a single center, retrospective, propensity score matching cohort study that explores the efficacy and safety of high flow nasal cannula and non-invasive ventilation in the treatment of acute respiratory failure associated with pulmonary arterial hypertension, stratified by the severity of right ventricular dysfunction. The study will compare two groups: high flow nasal cannula (HFNC) and non-invasive ventilation (NIV). Main objective: heart function parameters (e.g. TAPSE and RVSP) Secondary objectives: respiratory support success rate (defined as the avoidance of endotracheal introduction or death duration hospitalization), respiratory support duration, length of intensive care unit (ICU) stay, length of hospital stay, and in-hospital mortality. This study addresses whether NIV or HFNC should be prioritized for the treatment of acute respiratory failure associated with pulmonary arterial hypertension in patients with severe right ventricular dysfunction who require high flow nasal cannula and non-invasive ventilation. This study is of great significance as it is based on a patient stratification method of right ventricular dysfunction severity to evaluate the effectiveness of HFNC treatment and NIV in PH related ARF patients.

Interventions

DEVICE

HFNC treatment

HFNC treatment HFNC therapy. The initial flow rate of 50-60 L/min was subsequently adjusted to maintain an oxygen saturation (SpO2) ≥92%. The FiO2 was titrated to maintain the PaO2 between 60 and 80 mmHg.

DEVICE

NIV treatment

NIV treatment A Mindray SV300 ventilator (Mindray Medical International Limited, Shenzhen, China) was used to deliver NIV via an oronasal mask. The initial inspiratory positive airway pressure (IPAP) was 12-15 cmH2O and adjusted later to achieve a tidal volume of 6-8 mL/kg of predicted body weight and a respiratory rate of \<30 breaths/min. The expiratory positive airway pressure (EPAP) was established at 5-8 cmH2O. Additional-ly, FiO2 was titrated to maintain a PaO2 between 60 and 80 mmHg.
