Abstract:
Objective To explore the changes in cardiac index and oxygenation index in sepsis piglets after nitric oxide (NO) gas inhalation. Methods A piglet model of sepsis was induced by intravenous infusion of Gram-negative bacterial endotoxin (LPS), then the piglets were randomly divided into two groups. NO group (n=8) was administered with inhaled nitric oxide of 80ppm via volume control (VC) mechanical ventilation for one hour, while the control group (n = 4) received mechanical ventilation with VC and was observed for one hour to assess the stability of the model. The parameters of oxygenation and hemodynamics were measured by PICCO and arterial blood gas analysis every fifteen minutes for one hour. Results Injection of endotoxin induced a stable pig model of sepsis. PH, HCO3-, arterial oxygen pressure (PaO2), mean arterial pressure (MAP) and cardiac index in this model were significantly lower the baseline values (P < 0.01). Arterial oxygen pressure and cardiac index were significantly higher in N0 group than in the control group (P<0.01). Heart rate (HR), central venous pressure (CVP), global end-diastolic volume index (GEDI) and intrathoracic blood volume index (ITBI) did not significantly differ between NO group and the control group. Conclusions Inhalation of nitric oxide gas can significantly improve oxygenation and cardiac function in piglets with sepsis.
