Summary

Proning manoeuvre as an early treatment for acute severe hypoxic respiratory failure has been implemented recently during the COVID-19 pandemic. This method was proposed more than fifty years ago to improve gas exchange : Proning Severe ARDS (PROSEVA) trial, however, was the milestone which demonstrated mortality benefit in patients with severe ARDS. Nevertheless, few analysis were performed on the effects of the prone position after lung transplantion (LT). The aim of the study is therefore to relate LT primary graft dysfunction (PGD) pathophysiology, which occurs in postoperative setting, to prone-positioning effects on ventilation-perfusion matching, improved lung compliance and clinical outcomes of impairedorgan patients.

Conditions

  • Lung Transplant
  • Primary Graft Dysfunction

Interventions

PROCEDURE

Supine positioning

According to our local protocol, until December 2021, all patients developing PGD \>1 after LT were monitored in supine position for at least 24 hours, aiming at optimizing mechanical ventilation settings and right ventricular function, before considering PP. Only in case of radiological worsening or reduction in PaO2/FiO2 ratio patients were turned prone, generally between 24 and 48 hours after the diagnosis ('late PP' group), otherwise they were maintained supine ('supine' group).

PROCEDURE

Early pronation

According to our local protocol, starting from January 2022, all patients developing PGD \>1 after LT were monitored in supine position for at least 24 hours, aiming at optimizing mechanical ventilation settings and right ventricular function, before considering PP. Only in case of radiological worsening or reduction in PaO2/FiO2 ratio patients were turned prone, generally between 24 and 48 hours after the diagnosis ('late PP' group), otherwise they were maintained supine ('supine' group).

PROCEDURE

Late pronation

According to our local protocol, until December 2021, all patients developing PGD \>1 after LT were monitored in supine position for at least 24 hours, aiming at optimizing mechanical ventilation settings and right ventricular function, before considering PP. Only in case of radiological worsening or reduction in PaO2/FiO2 ratio patients were turned prone, generally between 24 and 48 hours after the diagnosis ('late PP' group), otherwise they were maintained supine ('supine' group).
