Re: Duration of stay in hospitals, days weeks months?
While I can't speak specifically to H1N1 and ECMO treatment LOS since we haven't had one yet, I can tell you about a few of our respiratory ECMO patients from past years.
It's correct that each ECMO patient has 2 nurses or a nurse/RT or a nurse/perfusionist 24/7. The bedside nurse does all the nursing care, which can be considerable in a heavily-sedated, intubated, ventilated patient with garden hoses sprouting from their neck or groin. The ECLS specialist monitors the pump and circuit, anticoagulation, blood gases, and a number of other parameters, as well as runs CRRT if needed. Remember that there will be litres of blood circulating under high pressure through the circuit outside the patient's body
every minute. Air leaks, blood leaks, fibrin deposits, clots, intrathoracic pressure changes, all these and more are the ECLS specialist's gig. If something goes wrong with the circuit, such as massive air entrainment or burst tubing, power failure or pump failure, the ECLS specialist repairs the system while the bedside nurse (and usually half of the staff on the unit as well) care for the patient. Repairing the circuit usually means taking the patient off ECMO so we try to make sure the actual stop time is as brief as possible. And with any long run, there will be the inevitable complete circuit change.
Cardiac ECMO is often only a few days' duration while the heart recovers from whatever caused it to fail or until a transplant occurs. (We are currently supporting an infant with a very complex constellation of cardiac defects who has been on for more than 6 weeks, but that's the exception for us.) Pulmonary ECMO is generally a lot longer process because the lungs recover much more slowly.
One of our respiratory kiddos had both adenovirus and RSV and was on ECMO for 8 weeks before we discontinued treatment and she died. That's
8 weeks in the ICU with two staff at the bedside 24/7 for 56 days. Another similar patient ran 5 1/2 weeks before her coagulopathy caused a massive bleed into her head and we discontinued treatment and she died. Other kids, one with severe asthma (who has been on ECMO twice now), have required upwards of two weeks, and our longest run with an intact survival was 12 weeks. WEEKS. And that's just the run time. After they're successfully decannulated, they may need ICU for several days to weeks in ICU for the other systems to recover enough to allow a ward transfer. LOS may run to months. One of our cardiac kiddies who went on to transplant was admitted to the ICU in November, went on ECMO after Christmas, was on 12 days, was transplanted in January, went to the ward in March and home in April. 5 months.
Do these examples make it a little clearer?
