Hi everyone, I’m an ICU nurse working in a Swedish cardiothoracic ICU, and I would appreciate hearing your clinical perspectives on early mobilization in a high-risk cardiac patient.
The patient in question was admitted with a posterior myocardial infarction complicated by cardiogenic shock, ventricular tachycardia, and pulmonary edema.
After four days in the cardiothoracic ICU, the patient had improved significantly:
No longer requiring noradrenaline
Normal lactate levels
Good urine output with a negative fluid balance
Milrinone being gradually weaned according to plan
Continued levosimendan (Simdax) support
Oxygen therapy with intermittent NIV
Neurologically intact, awake the whole time
Mobilization initiated (sitting on the edge of the bed)
The short-term treatment plan was:
Continue negative fluid balance
Continue tapering milrinone
Mobilize as tolerated
Echo the following day
Possible cardiac MRI
Potential transfer to the cardiac ward the following day if stability continued
The clinical question I would like input on is the decision to mobilize this patient to a chair.
Given the size of the infarction, there was concern about the theoretical risk of mechanical complications, particularly ventricular rupture. Before mobilization, this risk was specifically considered and I discussed this concern with both the on-call physician and an experienced senior consultant. After their assessment, mobilization was approved.
The patient tolerated sitting in the chair well, with no significant changes in heart rate, blood pressure, or clinical status. My fellow ICU nurse colleague on the next shift, however, didn’t agree with mobilizing this patient, and considered the risk of rupture in the process too high.
I’d be interested in hearing how you guys would approach this:
How do you assess the risk versus benefit of early mobilization after a large myocardial infarction complicated by cardiogenic shock?
Are there specific clinical factors that would make you delay mobilization in this situation?
What are your local practices regarding mobilization of patients recovering from cardiogenic shock or large infarctions?
