The control group were given conventional treatment while the study group was additionally treated with naloxone. Before and after the study, their serum levels of CK, CK-MB, cTnI were compared between the two groups. The following parameters (days in hospital, duration time of ventilation, oxygenation function (PaO2、OI and a/APO2), cure rate) alse compared between the two groups.Results The serum level of CK, CK-MB, cTnI in the study group were obviously lower than the control group. The oxygenation function of the study group was superior to the control group (P< 0.05). The ventilation function of the study group was better than the control group except PEEP. After treatment, the days in hospital, the duration time of ventilation and the oxygen days were better than the control group (P< 0.05). There was no significant statistical difference between the two groups in the cure rate.Conclusion Naloxone can protect myocardial and improve the effectiveness on the conventional treatment in the NRDS."/>
