The hemodynamic and respiratory effects of continuous negative and control-mode cuirass ventilation in recently extubated cardiac surgery patients: Part 2.
Negative-pressure ventilation (NPV) by external cuirass (RTX; Deminax Medical Instruments Limited, London, UK) in intubated patients after cardiac surgery improves hemodynamics measured by pulmonary artery catheter (PAC)-based methods with increased cardiac output (CO) and stroke volume (SV) without changing the heart rate (HR). The less-invasive pressure recording analytical method (PRAM) (MostCare; Vytech Health srl, Padova, Italy) allows radial artery monitoring of CO, SV, SV variation, and cardiac cycle efficiency (CCE). The authors investigated the hypothesis that NPV improves PRAM-based hemodynamics and arterial blood gas analysis in extubated cardiac surgery patients. ⋯ Extubated sedated cardiac surgery patients comfortably tolerated NPV with unchanged HR. SV and pH increased.

Effect of body mass index on early morbidity and mortality after isolated coronary artery bypass graft surgery.
Obesity is a risk factor for morbidity after isolated coronary artery bypass grafting. This study aimed to analyze the sole effect of body mass index (BMI) on early morbidity and mortality in patients after isolated coronary artery bypass grafting. ⋯ Underweight patients with a BMI <20 kg/m(2) are at increased risk of postoperative complications and mortality compared with normal-weight or overweight subjects.
