Anesthesiology and Intensive Care

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.

              Pain is often the patient’s presenting symptom.  It can provide useful clinical information and it is your responsibility to use this information to help the patient and alleviate suffering.     Manage pain wherever you see patients (emergency, operating room and on the ward) and anticipate their needs for pain management after surgery and discharge.  Do not unnecessarily delay the treatment of pain; for example, do not transport a patient without analgesia simply so that the next practitioner can appreciate how much pain the patient is experiencing.
