Swan-Ganz catheterization is an important technique for monitoring perioperative and postoperative cardiac pressures during open heart surgery. However, although a rare condition, resistance may be encountered while removing the catheter postoperatively and its removal must be accomplished through surgery. ⋯ When performing open heart surgery, the surgeon should not leave the Swan-Ganz catheter in the suture while closing the right or left atriotomy or during venous cannulation. In addition, the catheter should be moved after suturing to ensure that there is no entrapment.

Low systemic vascular resistance after cardiopulmonary bypass: incidence, etiology, and clinical importance.
Low systemic vascular resistance during and immediately after cardiac surgery in which cardiopulmonary bypass is utilized is a well-known phenomenon, characterized as vasoplegia, which appears with an incidence ranging between 5% and 15%. The etiology is not completely elucidated and the clinical importance remains speculative. ⋯ The occurrence of low systemic vascular resistance following cardiopulmonary bypass is as high as 21.8%. The etiology of this clinical condition is most probably multifactorial. Mortality is not affected by vasoplegia, but there is a trend to higher morbidity and prolonged stay in the ICU.

Fast-track recovery after coronary artery bypass surgery has influenced patient care positively. Predicting patients who fall off track and require prolonged (> or =7 days) hospitalization remains uncertain. The Parsonnet risk assessment score is effective in predicting length of stay, but is limited by inaccurate subdivision of risk categories. We simplified the Parsonnet risk scale to better identify patients eligible for fast-track recovery. ⋯ A simplified Parsonnet risk scale (three categories) is an effective tool in identifying factors limiting fast-track recovery. Low- and intermediate-risk patients represent the majority (82%) and respond well to fast-track methods. High-risk patients (18%) are limited by a greater percentage of female patients, reoperative CABG, and the very elderly, resulting in fast-track failure. Strategies to improve recovery in high-risk patients may include evolving off-pump techniques.
