New Study: CPAP Improves Cardiac Surgery Outcomes

WEDNESDAY, May 6 (HealthDay News) -- A few hours of postoperative treatment with continuous positive airway pressure (CPAP) may help improve outcomes in patients who've had heart surgery, finds a new study.

CPAP is commonly used to treat sleep apnea.

The study, published in the May issue of Chest, included 232 cardiac surgery patients who received standard postoperative treatment -- including 10 minutes of CPAP every four hours -- and 236 patients who received prophylactic CPAP for at least six hours after surgery.

The German researchers found that patients who received the prophylactic CPAP showed significantly improved arterial oxygenation without altered heart rate or mean arterial blood pressure.

These patients also experienced fewer pulmonary complications -- including hypoxemia, pneumonia and reintubation rates -- as well as a lower rate of readmission to the intensive care unit, the study authors found.

The findings suggest that CPAP may be a useful tool to prevent postoperative pulmonary complications in patients recovering from cardiac surgery, the researchers concluded.

The results are not too unexpected, since the vast majority of patients with heart disease will have some degree of obstructive sleep apnea.
but Dr. Park, maybe I misunderstand what's being said here, but the new thing that appears to be coming across in this study is that CPAP can be beneficial to people who do not necessarily have sleep apnea, in this case a representative sample of cardiac surgery patients, no?
Do we have any proof that they did not have apnea. I can see where it would be beneficial. Just don't think the study gives us enough info on the patient. I am wondering if the surgery itself might cause some central apnea due to the significant trauma on the heart.
I took my xPAP w/me when I had my last colonoscopy. They didn't use it when I was wheeled into recovery. I raised some holy h*ll about that before I left the facility. They were informed and well aware that I had COPD, that I had OSA, that my xPAP was set up and ready to go including the bleed in for the 02. Yet I was left unobserved on the monitor and then the monitor and 02 removed and left to sleep the rest of the sedative off unobserved w/o my xPAP. My mistake in sending my "driver" out to do some shopping instead of just sitting around waiting and being there to see that I was put on my xPAP.
