Abstract

Background: The pulmonary function test (PFT) was described the first time by Hutchinson in 1846 and was used by Tifno 100 years later. The respiratory function of patients who undergo cardiac surgery is affected by such factors as STERNOTOMY, release and ligation of the internal mammary artery, and mechanical ventilation. We sought to assess this impact on RESPIRATORY MECHANICS.Materials and Methods: This randomized, prospective study evaluated 110 patients who underwent elective coronary bypass graft surgery (CABG). The patient were trained for the PFT, and the test was performed once before surgery and subsequently one and three months postoperatively. The prospective PFT results of each patient were compared with the preoperative onehence obviating the need for matching. A t-test was employed to evaluate the results.Results: Our study population comprised 110 (75 men and 35 women) at a mean age of 58.14 kg. CARDIOPULMONARY BYPASS was performed in 108 patients, at an average time of 80.32 minutes. In all patients, in addition to the internal mammary artery, the saphenous vein was also used. The force expiratory volume in the first second, tidal volume, and vital capacity were assessed preoperatively and at one and three months postoperatively. Eighty-nine patients referred for the first follow-up visit and 29 patients referred for the second follow-up vist.Two patients died and were, therefore, excluded from the study. All the criteria of RESPIRATORY MECHANICS showed a considerable decrease one month after surgery compared with those before surgery. However, the criteria became closer to those before surgeries at the second follow-up visit. The changes were more significant in the male patients compared to the female ones.Discussiom: Our findings, in line with many other related studies, show that STERNOTOMY and ligation of the internal mammary artery to not have long-term effects on respiratory function and mechanics.
