some otolaryngologists administer topical phenylephrine for bleeding control in adenoidectomy surgery. absorption of this drug from surgical site can lead to increase in blood pressure due to vasoconstriction and then bradycardia related to baroreceptore reflex.  our case was an intraoperative arrest of a 9-yrs-old girl related to administration of topical phenylephrine during adenoidectomy how...

it is a great pleasure to receive two valuable comments about our article regarding sudden cardiac death (scd) in young athletes from two well known experts working in the field of preparticipation evaluation and prevention of sports injuries. we, as authors, generally agree with both authors' comments. however, some considerations should be re-emphasized here. .....

background: cardiovascular disease is an important non-obstetric cause of maternal and fetal /neonatal morbidity and mortality during pregnancy. for a pregnant woman with cardiac disease, the potential inability of the maternal cardiovascular system to contend with normal pregnancy-induced physiologic changes may produce deleterious effects on both mother and fetus. to determine the most freque...

background: information regarding serum biochemicalprofile can reflect cardiovascular performance in animals.although studies have evaluated the inter-relationship amongcardiovascular biomarkers in animals and human beings, thereare no reports of such a probable relationship in camelids.objectives: the aim of the present study was to provide dataon the correlations among cardiovascular biomarke...

conclusions this case highlights the potential severity of h1n1 infections and the utility of considering cardiac tamponade in patients presenting with influenza symptoms and circulatory collapse. case presentation we describe a case of a young female with no prior cardiovascular history who presents with a pericardial effusion and shock secondary to cardiac tamponade from pericarditis due to h...

materials and methods in a double blind randomized trial study, 100 patients undergoing elective cardiac surgery were randomized to using heparinized (n = 50) or non-heparinized (normal) saline flush (n = 50) to maintain patency of arterial catheter after operation. indwelling arterial catheters were checked daily for acceptable arterial waveform for three days as primary outcome measures. resu...

conclusions comparing the serum lactate level before operation and 24 hours after the operation showed that the number of received blood units had a significant effect on serum lactate. we found no significant effect for blood storage duration; however, the number of given blood units was more significant. patients and methods in a cross-sectional study, 228 patients referred to three hospitals...
