BACKGROUND AND PURPOSE Epinephrine administration during cardiopulmonary resuscitation increases cerebral blood flow by increasing arterial pressure. We tested whether potential beta-adrenergic effects of epinephrine directly influence cerebral blood flow and oxygen consumption independently of raising perfusion pressure. METHODS Four groups of seven anesthetized dogs were subjected to 8 minu...

BACKGROUND There are two competing theories of the mechanism of blood flow during cardiopulmonary resuscitation. The "cardiac pump" theory postulates that blood flows because the heart is squeezed between the sternum and the spine. The "thoracic pump" theory postulates that blood flows from the thorax because intrathoracic pressure exceeds extrathoracic vascular pressure and that flow is restri...

The cardiopulmonary resuscitation (CPR) persists as the best practice to maintain cerebral and coronary perfusion after cardiac arrest. Due to the chest compressions and ventilation maneuvers during resuscitation, there are common complications reported. Abdominal organs injuries occur in approximately 30% of patients, although studies show that they are under diagnosticated. The aim of this ar...

results according to the studies reviewed, induction of mild hypothermia in patients after cardiopulmonary resuscitation would lead to increased survival and better neurological outcome; however, studies on the complications of hypothermia or different methods of inducing hypothermia were limited and needed to be studied further. conclusions this study provides strategic issues concerning the i...

conclusions an insufficient formal education in cpr was registered for all groups, reflecting the lack of familiarity with new cpr methods. a team education, involving doctors and nurses may improve familiarity with cpr and patient outcomes. results the only difference between groups was regarding the male and female ratio, with more male surgeons (45, 55, and 11, p < 0.001). all doctors consid...

OBJECTIVES To evaluate the knowledge of basic life-support and training experience in cardiopulmonary resuscitation among the public in Hong Kong and to identify areas for improvement in public education. DESIGN Telephone interview using a structured multiple-choice questionnaire. SETTING Random cross-section of the Hong Kong public, from mid-March to May 2002. PARTICIPANTS Men and women ...
