Abstract

BACKGROUND Post cardiac surgery routine chest radiographs (CXRs), ordered without any clinical and laboratory indications, is a standard obligatory practice in many cardiothoracic centers. Routine CXRs incur cost, manpower, and radiation. The objective of this study is to assess early outcome in off-pump coronary artery bypass (OPCAB) patients with postoperative routine versus clinically indicated CXR protocols. MATERIALS AND METHODS This study is a randomized clinical trial conducted on 231 OPCAB candidates in Afshar Cardiac Center, Yazd, Iran. Patients were categorized into two groups. All 118 patients in group A had routine postoperative CXRs. The 113 patients in group B were selectively exposed to CXR only on clinical indications. All patients were postoperatively followed up for 30 days. Data gathered from both groups were statistically analyzed. RESULTS Routine postoperative CXRs obtained in 118 OPCAB group A candidates showed abnormal findings in 20 patients that did not require new intervention. One month follow-up of these patients showed no complications. In 113 OPCAB candidates of group B, 7 on-demand CXRs were obtained on clinical evaluation that required added intervention. In a 1-month follow-up of this group, five patients presented with symptomatic complaints. On re-examination, none needed readmission, intervention, or paraclinical evaluation. No complications were observed due to CXR elimination. CONCLUSION The study suggests that postoperative CXR selected on clinical grounds in place of routine CXR does not change early postoperative outcome of OPCAB procedure.
