Objective To investigate the effects of different postures on vital signs of patients with endotracheal tube after heart operations and to ensure the implementation of posture nursing care in the patients.Methods Thirty-five patients with endotracheal tube for over 24 hours after heart operation were made to assume semi-reclining position, left or right side-lying position for 1 hour respective and supine position for 1 hour at morning and evening. The HR, SBP, SaO_2 and comfort for different positions were observed and compared. Results There were no significant differences in HR and SBP among the three different postures (P0.05 for all). SaO_2 with semi-reclining and side-lying position at 0 and 30th min was higher than that of supine position (P0.05 for all). The patients with semi-reclining and lateral position had lower level of discomfort, including wound pain, chest tightness, and nervousness, compared with those with supine position. Conclusion Posture change has no negative effects on the vital signs of the patients with endotracheal tube after heart operation and it can promote oxygenation of lung and increase the level of comfort of the patients.
