Effect of Different Depths of Neuromuscular Blockade on Respiratory Mechanics in Patients With Moderate-severe Acute Respiratory Distress Syndrome

The initial bolus dose of cisatracurium injection is 0.05-0.1mg/kg, followed by a continuous infusion of 1ug/kg/min of cisatracurium, with data on vital signs, respiratory mechanics, TOF response, etc. recorded after a 15-minute wait. The maintenance infusion dose of cisatracurium is then gradually increased in a gradient of 0.5ug/kg/min, with data collection after a 15-minute wait after each increase. If the patient\'s spontaneous breathing completely disappears, the infusion dose of cisatracurium will no longer be increased, and the titration will end.
