BACKGROUND AND OBJECTIVES: Longitudinal, prospective, randomized, blinded Trial to assess the influence of pleural drain (non-toxic PVC) site of insertion on lung function and postoperative pain of patients undergoing coronary artery bypass grafting in the first three days post-surgery and immediately after chest tube removal.
METHOD: Thirty six patients scheduled for elective myocardial revascularization with cardiopulmonary bypass (CPB) were randomly allocated into two groups: SX group (subxiphoid) and IC group (intercostal drain). Spirometry, arterial blood gases, and pain tests were recorded.
RESULTS: Thirty one patients were selected, 16 in SX group and 15 in IC group. Postoperative (PO) spirometric values were higher in SX than in IC group (p<0.05), showing less influence of pleural drain location on breathing. PaO(2) on the second PO increased significantly in SX group compared with IC group (p<0.0188). The intensity of pain before and after spirometry was lower in SX group than in IC group (p<0.005). Spirometric values were significantly increased in both groups after chest tube removal.
CONCLUSION: Drain with insertion in the subxiphoid region causes less change in lung function and discomfort, allowing better recovery of respiratory parameters.
