Abstract:

Objective

To analysis of nitroglycerin on acute respiratory distress syndrome (ARDS) patients with low tidal volume ventilation strategies + pulmonary reexpansion after cardiopulmonary function, inflammatory factors and immune function.

Methods

From September 2015 to May 2019, 98 patients with ARDS were randomly divided intoNitroglycerin group 50 cases and control group 48 cases. All patients were treated with small tidal volume ventilation strategy and pulmonary revascularization. The Nitroglycerin group was treated with intravenous nitroglycerin injection. The cardiopulmonary function, inflammatory factors and immune function associated indexes in the two groups were detected before treatment, 6 h and 24 h after treatment.

Results

6 h and 24 h after treatment, the left ventricular ejection fraction and cardiac index (CI) were significantly higher than those before treatment, serum N-terminal B type brain natriuretic peptide (NT-proBNP) levels were significantly lower than those before treatment, and the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and FEV1/FVC were significantly higher than those before treatment (P<0.05). 6 h after treatment, there were no significant differences in cardiopulmonary function indexes between the two groups (P>0.05). 24 h after treatment, the improvement of cardiopulmonary function in theNitroglycerin group was more significant than that in the control group (P<0.05). 6 h and 24 h after treatment, the levels of serum C reactive protein (CRP), procalcitonin (PCT) and interleukin-6 (IL-6) were significantly lower while the levels of CD3+ , CD4+ and CD4+ /CD8+ were significantly higher than those before treatment (P<0.05). 6 h and 24 h after treatment, the levels of CRP, PCT and IL-6 in theNitroglycerin group were significantly lower while the levels of CD3+ , CD4+ and CD4+ /CD8+ were significantly higher than those in the control group (P<0.05).

Conclusion

Nitroglycerin combined with low tidal volume ventilation and lung recruitment maneuver in the treatment of ARDS can play a better role in protecting the cardiopulmonary function. The regimen can effectively relieve the inflammatory reactions and enhance immune function.
