ABSTRACT

The study was done to determine the effect of different types of drain to postoperative effusion and pain on patients who enderwent coronary artery bypass grafting (CABG).

50 patients data were evaluated prospectively. Standart drain was placed into 7-8th intercostal area (Group 1). L drain was placed into pleural area (Group 2). Demographic data, drainage amounts were written from hospital documents. Postoperative phericardial and pleural effusion was determined by echocardiography and chest x-ray. Verbal Rating Scale was used to dedicate pain score. Data were analyzed by T test.

Groups demographic data were similar. Drainage was 652.0±328.3 ml (Group 1), 620.0 ± 169.5 ml (p=0.04) in Group 2. Pain score before taking of drain was 2.0±2.6 (Group 1), 1.0±1.6 (p=0.01) in Group 2, after taking of drain was 4.7±3.0 (Group 1), 2.1±2.0 (p=0.05) in Group 2. Fifteen day mean phericardial effusion was 0.2±0.4 cm (Group 1), 0.1±0.3 (p=0.05) in Group 2. There was no difference between other parameters.

Using both types of drain seems to be safe but L drain is more comfortable because of less pain.
