VIEIRA, Irinea Beatriz Carvalho Ozelami; VIEIRA, Fabiano F.; ABRAO, João  e  GASTALDI, Ada Clarice. Influence of pleural drain insertion in lung function of patients undergoing coronary artery bypass grafting. Rev. Bras. Anestesiol. [online]. 2012, vol.62, n.5, pp.702-708.

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. PaO2 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.
