Objective: To evaluate associations between post-operative complications in patients who survive surgery and in-hospital deaths and lengths of hospital stays of patients who undergo coronary artery bypass graft surgery
Methods: Patients who underwent coronary artery bypass graft surgery and survived the operating theater were randomly selected. Information on complications and hospital lengths of stay until hospital discharge or death were retrospectively collected based on medical records and declarations of death. These aspects were estimated according to the presence of complications, frequency of complications, mortality, relative risk and attributable population risk.
Background: Risk stratification models are used to assess the risk of death in surgery.
Objective: To conduct a critical analysis of the EuroSCORE logistic model (ES) application in 2,692 patients undergoing Coronary Artery Bypass Grafting (CABG) in four public hospitals in the Rio de Janeiro Municipality, from 1999 through to December 2003.
Methods: Random samples of 150 medical records for surviving and deceased patients were selected at four public hospitals in the City of Rio de Janeiro.
Objective: To estimate in-hospital mortality and prevalence of complications of percutaneous transluminal coronary angioplasty (PTCA) in public hospitals.
Methods: Data for 2,913 PTCA were obtained from the Brazilian National Health System (SUS) Hospital Authorization Database in the city of Rio de Janeiro, Southeastern Brazil, between 1999 and 2003. After simple random sampling and data weighting, 529 medical records of patients undergoing PTCA, including all deaths, in four public hospitals (federal and state university, and federal and state reference hospitals) were studied.
Objective: To report initial experience with myocardial revascularization surgery (MRS) performed on patients who were totally awake and without an endotracheal tube.
Methods: Between January 1994 and May 2001, 272 patients underwent MRS without extracorporeal circulation. In 24, the operations were performed without the use of an endotracheal tube and with the patients totally awake and breathing normally.
