Study To Compare The Effect Of Supine Lying Position Along With Mobilization Over Half Lying Position Head Up 45 Degree In Patients Following Open Heart Surgery

Effect of body positioning on lung volumes and capacities have been well established over past three decades with supine lying being the least physiological and standing the most physiological position. This study with same subject cross over design aims to compare the effect of supine lying position along with mobilization over half lying position in subjects following open heart surgery in relation to heart rate, blood pressure, partial pressure of oxygen and carbon dioxide. 30 subjects who underwent open heart surgery between 15 January 2005 to 30 January 2006 were studied.12 patient out of 30 patients studied underwent mitral valve replacement,7 patients underwent coronary artery bypass grafting ,3 patients underwent aortic valve replacement ,2 patients have undergone left atrial myxoma excision ,3 patients have undergone ventricular septal closure and 1 each have undergone atrial septal defect closure,left atrial clot excision and repair of tetralogy of fallot .Significant changes were observed between HLrr with Serr (p < .005) while non significant changes were observed in other compared variables. The overall result of this study indicate that the half lying position (Hi) is equally effective as supine lying with mobilization. Thus the null hypothesis is accepted.
