Whereas heparin is the most widely used intravenous anticoagulant in the US for the treatment of thromboembolic disease and is a seminal adjunct to many clinical procedures, its use can cause serious adverse events. Heparin-induced thrombocytopenia (HIT) has emerged as one of the most frequently seen complications of heparin therapy and can be a life-threatening immunohematological challenge for patients requiring cardiopulmonary bypass (CPB) with obligatory heparin exposure. Unfortunately, lack of convenient monitoring techniques and the presence of HIT and other comorbidities in the complex patient frequently limits or precludes the use of most alternatives to heparin anticoagulation during CPB. This case report describes the successful use of the celite activated clotting time and high-dose thrombin time, while using the direct thrombin inhibitor Argatroban as an alternative to heparin anticoagulation during CPB in a high-risk patient presenting with type II HIT, end-stage renal failure, and ischemic cardiomyopathy with ventricular fibrillatory arrest.

We reviewed our experience to determine the role of endoscopic airway stents in children with tracheobronchial obstruction. ⋯ Tracheobronchial stenting in children is only rarely needed and often undertaken in dire circumstances. The procedure has led to significant symptomatic benefit in dyspneic children and has enabled ventilator-dependent children to be extubated. Medium-term outlook after stenting with self-expanding metal stents for vascular compression of the airway is encouraging. The long-term outcome remains uncertain, however, and is ultimately influenced by the underlying disease.

Randomized Controlled Trial Comparative Study Clinical Trial
Blood loss in infants and children for open heart operations: albumin 5% versus fresh-frozen plasma in the prime.
Infants and children undergoing cardiopulmonary bypass become substantially hemodiluted secondary to the volume used to prime the oxygenator. Fresh-frozen plasma has been included in the prime to lessen dilution of clotting factors and correspondingly minimize blood loss and transfusions. ⋯ Substitution of albumin 5% for fresh-frozen plasma in the prime of acyanotic patients weighing 10 kg or less who undergo noncomplex operations requiring cardiopulmonary bypass significantly reduces perioperative transfusions without increasing blood loss. Further investigation is needed to determine whether increased blood loss is associated with increased transfusions when albumin 5% is substituted for fresh-frozen plasma in the prime of infants and children who are cyanotic or undergoing complex operations.

Clinical Trial Controlled Clinical Trial
Cognitive changes with coronary artery disease: a prospective study of coronary artery bypass graft patients and nonsurgical controls.
Cognitive impairment after coronary artery bypass grafting (CABG) is well recognized, but previous investigations have been limited by lack of an appropriate control group. We compared changes in cognitive performance at 3 and 12 months after CABG with those in a control group of patients with comparable risk factors for coronary artery disease (CAD) who had not undergone surgery. ⋯ The prospective longitudinal neuropsychological performance of patients with CABG did not differ from that of comparable nonsurgical control subjects with CAD at 3 months or 1 year after base line examination. This suggests that the previously reported cognitive decline during the early postoperative period after CABG is transient and reversible. Continued follow-up will determine whether a specific "late decline" occurs in CABG patients but not in nonsurgical control subjects with similar risk factors for cardiovascular and cerebrovascular disease.

Randomized Controlled Trial Comparative Study Clinical Trial
Suction versus water seal after thoracoscopy for primary spontaneous pneumothorax: prospective randomized study.
The objectives of the study were to review our experience of video-assisted thoracoscopic apical pleurectomy and to evaluate whether suction or water seal is superior in the postoperative treatment of primary spontaneous pneumothorax. ⋯ Video-assisted thoracoscopic apical pleurectomy is effective and safe for treating primary spontaneous pneumothorax. Placing chest tubes on water seal after a brief period of suction shortens the duration of chest tube placement and hence the hospital stay.
