Abstract:
Objective To study l-arginine aerosolized inhalation's protective effect on pulmonary ventilation of the pulmonary-arterial-hypertension patients during the early stage after pulmonary lobectomy,and its preventive effect on reducing postoperative complications.Methods 54 cases of pulmonary lobectomy patients with preoperative plumonary arterial hypertension were divided into two groups randomly-Group A was given L-arginine aerosolized inhalation within 4 h after the operation;Group B was given the same dose of aerosolized inhalation of physiological saline as contrast(other postoperative medication being the same with Group A).Compare the two groups of patients in terms of oxygenation index(PaO2/FiO2),alveolararterial oxygen difference(PA-aO2),nitric oxide(NO) concentration,ultrasonic cardiogram,mechanical ventilation duration,ICU duration,occurances of hemodvnamic disturbance and arrhythmia,and differences in postoperative hospital stay.Results The oxgenation index and the content of NO in plasma of Group A were higher than that of Group B(P ＜0.001);the alveolar-arterial oxygen difference and the postoperative pulmonary arterial pressure detected by UCG of Group A were lower than that of Group B(P ＜ 0.001);the postoperative mechanical ventilation duration,ICU duration,occurances of hemodynamic disturbance and arrhythmia of Group A were all lower than that of Croup B(P ＜ 0.05).Conclusion The postoperative l-arginine aerosolized inhalation during the early stage after pulmonary lobectomy has positive effect on the lung protection of the pulmonary-arterial-hypertension patients and it can reduce the perioperative complications and postoperative hospital stay of such patients.
