Mild therapeutic hypothermia after cardiac arrest has become standard in post-resuscitation care in many hospitals as it is recommended by current guidelines
Some authors report that both b1-adrenoceptors and aadrenoceptors increase their sensitivity to catecholamines during hypothermia [18,20,21,22] as b1-adrenoceptor activity was potentiated by low temperature, and they claim the existence of hypothermia-induced supersensitivity and increased agonist activity for b1-adrenoceptors

Introduction

A1 Update on therapeutic temperature management Gregor Broessner1*, Marlene Fischer, Gerrit Schubert, Bernhard Metzler, Erich Schmutzhard1 1Department of Neurology, Medical University, Innsbruck, Austria; 2Department of Neurosurgery, Medical University, Innsbruck, Austria; 3Department of Cardiology, Medical University, Innsbruck, Austria Critical Care 2012, 16(Suppl 2):A1It is a pleasure to announce the 2nd Innsbruck Hypothermia Symposium. It could be shown that hypothermia may lead to increased rate of infections, hypotension, shivering, disturbances in blood clotting, rewarming injuries and significant changes in pharmacokinetics and pharmacodynamics possibly limiting outcome effects of the treated patients [4,5,6,7,8]. Aggressive treatment of fever in the ICU without risk elevation through the side effects of therapeutic hypothermia led to the concept of controlled prophylactic normothermia This concept is based upon strict control of body core temperature with a target of 36.5°C beginning as early as possible with the goal of complete fever prevention. All planned measures to reduce reperfusion damage before revascularization should preferably be applied in a very short time
