Filter by:The purpose of this study is to determine whether breathing high levels of oxygen during surgery affects oxygen levels after surgery. The second purpose of this study is to determine whether giving positive end expiratory pressure PEEP and high oxygen together affects patients oxygen levels after surgery.
Despite the lack of trials proving the efficacy of DNase in non cystic fibrosis patients, it is currently heavily used in this population. In fact, per evidence of barcode scanning via Meditech computer system at OU Medical Center 93% of the DNase prescribed in 2005 was for non Cystic fibrosis patients with an estimated yearly cost of $341,968.15.In vitro studies showed that the effect of Dnase was minimal on sputum viscosity when compared to Hypertonic saline . Furthermore recent studies on hypertonic saline in cystic fibrosis patients showed that it is an inexpensive and safe therapy when preceded by a bronchodilator in patients with cystic fibrosis. We hereby propose a prospective randomized trial to compare the efficacy of hypertonic saline, DNase, vs. normal saline in the treatment of atelectasis in non cystic fibrosis, mechanically ventilated patient.
Pregnancy promotes respiratory system's restrictive component. This study observes the generation of atelectasis during labor.
CT-PET image fusion has the potential to differentiate 'tumor' from 'atelectasis' much better than the CT-scan in patients with non-small cell lung cancer who also have atelectasis. This however has never been validated on a histological level. In this study patients with non small cell lung cancer and atelectasis who are eligible for surgery undergo a CT-scan and a PET-scan prior to surgery. The resection specimen will be compared to the preoperative imaging.
