Anesthesiology and Intensive Care

    What is new in 2017 STEMI Guidelines. BMS = bare metal stent; DES = drug eluting stent; IRA = infarct related artery; i.v. = intravenous; LDL = low-density lipoprotein; PCI = percutaneous coronary intervention; SaO2 = arterial oxygen saturation; STEMI = ST-elevation myocardial infarction; TNK-tPA = Tenecteplase tissue plasminogen activator.

1.  Patients with dehydration, hypovolemia or who have impaired renal  function are at increased risk for decreasing renal function or renal  failure.

     Serum marker sensitivity relative to the time of onset of chest pain in the patient with acute myocardial infarction (AMI):

         The muscarinic antagonists compete with neurally released acetylcholine ( ACh )   for access to muscarinic cholinoceptors and block  ACh’s  effects. The results are faster heart rate, sedation,  and dry mouth. With the exception of the quaternary  ammonium compounds that do not readily cross the  blood-brain barrier and have few actions on the CNS,  there is no significant specificity of action among these drugs; they block all muscarinic effects with equal efficacy, although there are some quantitative differences in effect.
