OBJECTIVE: To evaluate respiratory muscle strength, oxygenation and chest pain in patients undergoing off-pump coronary artery bypass (OPCAB) using internal thoracic artery grafts comparing pleural drain insertion site at the subxyphoid region versus the lateral region. METHODS:Forty patients were randomized into two groups in accordance with the pleural drain site. Group II (n = 19) -pleural drain exteriorized in the intercostal space; group (SI) (n = 21) chest tube exteriorized at the subxyphoid region. All patients underwent assessment of respiratory muscle strength (inspiratory and expiratory) on the pre, 1, 3 and 5 postoperative days (POD). Arterial blood gas analysis was collected on the pre and POD1. The chest pain sensation was measured 1, 3 and 5 POD. RESULTS: A significant decrease in respiratory muscle strength (inspiratory and expiratory) was seen in both groups until POD5 (P <0.05). When compared, the difference between groups remained significant with greater decrease in the II (P <0.05). The blood arterial oxygenation fell in both groups (P <0.05), but the oxygenation was lower in the II (P <0.05). Referred chest pain was higher 1, 3 and 5 POD in the II group (P <0.05). The orotracheal intubation time and postoperative length of hospital stay were higher in the II group (P <0.05). CONCLUSION: Patients submitted to subxyphoid pleural drainage showed less decrease in respiratory muscle strength, better preservation of blood oxygenation and reduced thoracic pain compared to patients with intercostal drain on early OPCAB postoperative.
