ObjectivesSurgical stress and pain affect the respiratory condition of patients and can cause complications that affect morbidity and mortality in cardiac surgeries. The authors studied the effect of thoracic epidural analgesia (TEA) versus traditional intravenous analgesia on postoperative respiratory mechanics in cardiac surgery.DesignRetrospective, observational study.SettingSingle, university hospital.ParticipantsPatients undergoing cardiac surgery.InterventionsComparing the postoperative respiratory effects of TEA with bupivacaine or intravenous analgesia with tramadol or paracetamol or dexmedetomidine.Measurements And Main ResultsA total of 1,369 patients were screened, and 1,280 patients were enrolled in the study. Postoperative sedation and analgesia level, extubation times, respiratory complications, lengths of intensive care and hospital stay, morbidity, and mortality were compared. Additional sedative and analgesic drug requirement in the TEA group (25.3% and 60.1% respectively) were significantly lower than the intravenous group (41.4% and 71.8%, respectively; p < 0.001 and p < 0.05, respectively). Extubation time in the TEA group also was significantly lower than the intravenous group (p < 0.01). Respiratory complication and hospital stay in the TEA group were lower than intravenous group (p < 0.05).ConclusionsTEA provided better postoperative respiratory condition via better sedative analgesia in cardiac surgery.Copyright © 2020 Elsevier Inc.
