Arterial blood gas (ABG) analysis is useful in evaluation of the clinical condition of critically ill patients; however, arterial puncture or insertion of an arterial catheter may cause many complications. This study evaluated whether pH, partial pressure of carbon dioxide (PCO2) and bicarbonate (HCO3-) values of venous blood gas (VBG) could accurately predict their ABG analogs for patients with acute respiratory failure treated by mechanical ventilation in an intensive care unit (ICU). ⋯ Venous blood gas can accurately predict the ABG values of pH, PCO2 and HCO3- for patients with acute respiratory failure being treated with mechanical ventilation.

Comparative Study
Comparison of outcome of off-pump coronary artery bypass surgery and conventional coronary artery bypass surgery.
Off-pump coronary artery bypass grafting (CABG) [OPCAB] is preferred to conventional CABG with cardiopulmonary bypass (CPB) for many specific subgroups, such as elderly patients and high-risk patients. Whether OPCAB should be the first choice of surgical procedure for a wider range of coronary artery disease patient subgroups remains controversial. The purpose of this study was to compare the clinical results of OPCAB and CPB in our hospital. ⋯ Use of OPCAB in CABG operation was associated with improved in-hospital outcome and similar follow-up outcome compared to CPB. No subgroup had a worse outcome with OPCAB.
