conclusions music therapy is a safe, simple, inexpensive, and non-invasive nursing intervention, which can significantly alleviate patients’ anxiety during coronary angioplasty. patients and methods this was a randomized controlled trial, conducted in the catheterization laboratory unit of baqiyatallah hospital, in tehran, iran. a sample of 64 patients, who were planned to undergo coronary angi...

a b s t r a c t a 36-year-old male patient with posttraumatic cervical cord damage and resultant quadriparesis, demonstrated hypotension and periods of bradycardia. for most of his two-month stay in the intensive care unit (icu), he was dependent on dopamine support to maintain hemodynamic stability. keeping in mind evidence from the literature, that electrostimulation of acupoints neiguan (pc ...

OBJECTIVE The aim of this study was to (1) observe the extent to which hemodynamic and glucose measurements change in patients submitted to a dental procedure with and without a local anesthetic and a vasoconstrictor (LAVA; 2% mepivacaine with adrenaline 1100,000) and (2) correlate those parameters with the patients' anxiety levels. METHOD This was an unblinded, random, prospective, and obser...

Impedance Cardiography (ICG) is a noninvasive technique for monitoring stroke volume, cardiac output and other hemodynamic parameters, which is based on sensing the change of thoracic electrical impedance caused by blood volume change in aorta during the cardiac cycle. Motion artifact and respiratory artifact can lead to baseline drift in ICG signal, particularly during or after exercise, which...

Pirbuterol hydrochloride, an orally effective beta-adrenergic agonist, improves hemodynamic abnormalities in patients with congestive heart failure, but its effects on myocardial oxygen consumption (MVO2) and coronary blood flow have not been characterized. We studied the effects of 20-30 mg of oral pirbuterol on myocardial metabolic and hemodynamic parameters in 12 patients (six with coronary ...

Flushing hemodynamic catheters is essential to maintain patency and therefore ensure accurate hemodynamic measurements, arterial blood sampling, and cardiac output determinations. Patency of hemodynamic catheters has been maintained for decades in critical care settings with pressurized infusions of heparinized saline to prevent clots from forming around or within catheters. Recently, the use o...
