BACKGROUND Profound bradycardia during eye surgery is potentially serious event. In clinical practice this Oculocardiac Reflex (OCR) is most often encountered during squint surgery. The objective of this study was to assess the occurrence of OCR and prove the effect of anticholinergic premedication (atropine) to prevent OCR. METHODS This study comprises of sixty patients (age 2-30 years) oper...

A new multipurpose flow-directed pulmonary arterial catheter has been developed and evaluated in 30 patients with acute cardiopulmonary dysfunction. The catheter permits monitoring of the bipolar atrial electrogram, pulmonary arterial or wedge pressure, central venous pressure, and cardiac output, plus atrial pacing. The standard Swan-Ganz thermistor-equipped catheter was modified to incorporat...

Chemical warfare agents were demolished by US soldiers at Khamisiyah, Iraq, in March 1991. The authors investigated postwar morbidity for Gulf War veterans, contrasting those who may have been exposed to low gaseous levels of nerve agents and those unlikely to have been exposed. Cox regression modeling was performed for hospitalizations from all causes and hospitalizations from diagnoses within...

\s=b\This study was designed to evaluate the impact of antihypertensive therapy on cardiac dysrhythmias in 13 hypertensive patients who received calcium entry blockers and in 10 hypertensive patients who received hydrochlorothiazide. Mean arterial pressure fell to a similar extent in both treatment groups; however, left ventricular mass index decreased (from 102\m=+-\4to 95\m=+-\2 g/m2) only in...

Electrical cardiac pacing for the management of bradyarrhythmias was first described in 1952, and permanent transvenous pacing devices were introduced into clinical practice in the early 1960s. The first devices for endocardial defibrillation were implanted in surviving victims of sudden cardiac death in 1980. Implanted electrical devices for the management of cardiac dysrhythmias have changed ...

Racemic propranolol has been shown to be an effective antidysrhythmic agent in many circumstances (Frieden, 1967; Gettes and Surawicz, 1967; Gibson and Sowton, 1969), including the management of ventricular fibrillation following infarction (Sloman, Robinson, and McLean, 1965). Its depressant effects on myocardial function (Bay, Lund-Larsen, Lorentsen, and Sivertssen, 1967) limit its use in ser...

BACKGROUND The full extent of cardiovascular morbidity in inflammatory bowel disease is not well understood. OBJECTIVE To comprehensively study the association of different cardiovascular diseases in hospitalized patients with inflammatory bowel disease (IBD) using a large database. METHODS We used the Nationwide Inpatient Sample (NIS) database to perform a cross-sectional study. The study ...

Compromised cardiovascular performance, occurrence of serious cardiac dysrhythmias, cardiac atrophy, orthostatic intolerance, reduced aerobic capacity, operational impacts of regular physical exercise, and space radiation are risks of space flight to the cardiovascular system identified in the 2007 NASA Human Integrated Research Program. An evidence-based approach to identify the research prior...

Allergic rhinitis (AR) is a very common disease, occurring in approximately 10% of children and up to 20% of adolescents. It is often underdiagnosed and its importance as a cause of morbidity is also underestimated, especially in asthmatic children. It has been estimated that 75% of asthmatic children suffer from AR, and its prevalence has increased during the last years, due to changes in envi...
