BACKGROUND: Primary graft dysfunction (PGD) is one of the most common causes of early death after orthotopic heart transplantation. Mechanical circulatory support devices are required for severe forms of PGD. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) and temporary ventricular assist device (VAD) support have both been reported to be useful for severe PGD. METHODS: Between January 2007 and December 2015, 597 patients received a heart transplant at our center...

Objectives Pulmonary dysfunction is a recognized postoperative complication that may be linked to use of cardiopulmonary bypass. The off-pump technique of coronary artery bypass aims to avoid some of the complications that may be related to cardiopulmonary bypass. In this study, we compared the influence of on-pump or off-pump coronary artery bypass on pulmonary gas exchange following routine surgery. Methods Fifty patients (mean age 60.4 ± 8.4 years) with no preexisting lung disease and good left ventricular function undergoing primary coronary artery bypass grafting were prospectively randomized to undergo surgery with or without cardiopulmonary bypass...

Malignant Hyperthermia (MH) is a life-threatening biochemical process of hypermetabolism brought about in susceptible individuals by a triggering drug or event. Type A aortic dissections are surgical emergencies requiring cardiopulmonary bypass and frequently deep hypothermic circulatory arrest. We present a case of suspected MH in a patient undergoing emergent repair of a type A aortic dissection. Upon arrival at our institution, the patient had multiple signs of MH. However, no known triggering agent had been administered...

The objective of the current study was to investigate effects of sevoflurane on cardiopulmonary function in patients undergoing coronary artery bypass grafting (CABG). In this study, 60 cases of patients with coronary heart disease (CHD) were selected and randomly divided into the sevoflurane group (group S) and the control group C (group C) with 30 cases in each group. The two groups received intravenous anesthesia. The patients of group C were only given oxygen mask and physiological saline to keep vein open; while the patients of group S were administered with 1% sevoflurane immediately after the beginning of cardiopulmonary bypass (CPB) until the end of the treatment...

BACKGROUND: As 6% hydroxyethyl starch (HES) 130/0.40 or 130/0.42 can originate from different vegetable sources, they might have different clinical effects. The purpose of this prospective, randomized, double-blind controlled trial was to compare two balanced tetrastarch solutions, one maize-derived and one potato-derived, on perioperative blood loss in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). METHODS: We randomly assigned 118 patients undergoing elective cardiac surgery into two groups, to receive either a maize- or a potato-derived HES solution...

The difficult airway (DA) is a common problem encountered in patients undergoing cardiac surgery. However, the challenge is not only just establishment of airway but also maintaining a definitive airway for the safe conduct of cardiopulmonary bypass from initiation to weaning after surgical correction or palliation, de-airing of cardiac chambers. This review describes the management of the DA in a cardiac theater environment. The primary aims are recognition of DA both anatomical and physiological, necessary preparations for (and management of) difficult intubation and extubation...

BACKGROUND: Serum lactate and base deficit have been shown to be a predictor of morbidity and mortality in critically ill patients. Poor preoperative oxygenation appears to be one of the significant factors that affects early mortality in tetralogy of Fallot (TOF). There is little published literature evaluating the utility of serum lactate, base excess (BE), and oxygen partial pressure (PO 2 ) as simple, widely available, prognostic markers in patients undergoing surgical repair of TOF...

INTRODUCTION: Cardiopulmonary bypass (CPB) can cause stress response that increases levels of cytokine and catecholamine in plasma, resulting in hyperglycemia. In adults, it has been demonstrated that remifentanil infusion during CPB could prevent increases of cytokine, catecholamine, and blood glucose levels, but such effects of remifentanil in children have not been elucidated. AIM: In this study, we investigated the preventive effects of remifentanil on blood glucose and lactate levels during CPB in children...

INTRODUCTION: While off pump coronary artery bypass surgery is practiced with an intention to reduce the morbidity associated with cardiopulmonary bypass, the resultant 'hypercoagulability' needs to be addressed. Complications such as cavitary thrombus possibly due to the hyper coagulability after off pump coronary artery bypass surgery have been described. Many clinicians use higher doses of heparin - up to 5 mg/kg in order to thwart this fear. Overall, there appears to be no consensus on the dose of heparin in off pump coronary artery bypass surgeries...
