Rapid Loss of Hemoglobin Compound May Deter Oxygen Delivery
ISSUE: AUGUST 2010 In an effort to better understand the increased risk from red blood cell transfusions for organ failure, heart attack, stroke and even death, North Carolina researchers have found that reduced levels of S-nitrosylated hemoglobin (SNO-Hb) may be a significant factor.

Cryospray Against Airway Tumors Leads to Unexpected Complications
ISSUE: AUGUST 2010 Spray cryotherapy with liquid nitrogen has been used effectively for ablating esophageal tumors. Some facilities even perform the technique in an outpatient setting under sedation. However, spray cryotherapy for treating advanced airway lesions—when other treatment options are limited—is more recent, and few reports of its effectiveness have been published (J Thorac Cardiovasc Surg 2010;139:781-782).

Preventive Strategy To Reverse Cerebral Desaturation Includes Algorithm
ISSUE: JULY 2010 Serious complications can develop after surgery in patients who experience prolonged episodes of decreased oxygen to the brain during their procedures. And almost half of patients undergoing complex cardiac surgery experience a significant decline in cerebral oxygen saturation. However, according to a recent study, the use of near-infrared reflectance spectroscopy and an interventional algorithm pioneered by Montreal clinicians reverses almost 90% of these cases.
