Reduced inotropic support after aprotinin therapy during pediatric cardiac operations.
BACKGROUND Several reports indicate that aprotinin treatment before and during cardiopulmonary bypass (CPB) might have a protective effect on the myocardium. We evaluated the hemodynamic effects of perioperative aprotinin treatment. METHODS We conducted a randomized, double-blind, placebo-controlled trial in 34 infants (mean age, 2.5 years) who had cardiac operations. Half of the patients rec...
متن کاملCARDIAC ELECTRICAL DYSFUNCTION IN ACUTE BRAIN LESIONS
This study briefly reviews the heart abnormalities in diverse intracranial pathologies, including strokes, spontaneous and traumatic subarachnoid hemorrhage and intracranial hemorrhage, and presents the results of a one-year prospective study of heart abnormalities in patients with moderate to severe head injuries and subarachnoid hemorrhage. Different abnormalities such as: QT -interval, T...
متن کاملRelationship between cardiac troponin I (cTnI) release during cardiac operations and myocardial cell death
The awareness of the diagnostic difficulty and the documented high mortality risk of perioperative myocardial infarction (PMI) has led to the wide use of work up to rule out PMI after major noncardiac operations. This has caused stable postoperative patients to be kept in monitored hospital beds for extended periods of time and to be subjected to additional tests. We hypothesized that the morta...
متن کاملCerebral hyperperfusion during surgical resection of high-flow arteriovenous malformations.
Cerebral hemodynamics were evaluated in 16 patients with arteriovenous malformations (AVMs) using intraoperative thermogradient or laser Doppler flowmeter. The postexcision/preexcision blood flow ratio was determined. Two of seven patients with large AVMs (> or = 4 cm) developed a postoperative hematoma. Their flow ratios were larger than 1.9. In 4 patients with large AVMs, their blood flow rat...
متن کاملCardiac operations in cirrhotic patients.
It is well recognized that morbidity and mortality rates after cardiac operations with cardiopulmonary bypass in patients with cirrhosis are significantly higher than those in the general cardiac surgical population. Several contributing factors peculiar to cirrhosis, such as compromised nutritional status, increased susceptibility to infections, and impaired coagulopathy, may be responsible fo...
