Pulmonary Vasodilator and Inodilator Drugs in Cardiac Surgery: A Systematic Review With Bayesian Network Meta-Analysis

J Cardiothorac Vasc AnesthPublished Systematic review and Bayesian network meta-analysis of randomised trials

Authors' conclusion

Inhaled prostacyclin was the only pharmacologic intervention whose use is supported by a statistically discernible improvement in mortality in the perioperative cardiac surgery setting as treatment of pulmonary hypertension.

Study context

Population
Adults with pulmonary hypertension undergoing elective cardiac surgery (perioperative setting)
Participants
1,879 adults · 28 studies
Comparison
Inodilators and pulmonary vasodilators vs placebo or standard care
Outcome
In-hospital mortality

Pooled result

As reported in the abstract

In-hospital mortality (10 studies, 855 patients, 12 interventions)
  • Only inhaled prostacyclin showed a statistically discernible improvement in mortality
  • Inhaled prostacyclin vs Placebo or standard care: CrI 1.26 × 10-17 - 0.7
  • CrI

Further pooled results

ICU LOS

Inhaled prostacyclin and nitric oxide associated with reduced ICU stay

Ventilation duration, stage 3 AKI, cardiogenic shock requiring mechanical support, change in mean pulmonary artery pressure

No intervention reached a statistically evident difference vs usual care or placebo
