Definition
30mg cortisol by body equals 5-7.5 mg of predinsone |

a pt on more than 20mg/day of predinson for more than 3 weeks can cause adrenal insufficiency that lasts up to one year after the cessation of the steroids. |
|
|
Term
MAOI and surgery..what to know? |

MAOI have long half life of 3 weeks. If you discontinue them three weeks in advance you place patient at high risk of suicide and depression. So just continue MAOI and tailor anesthesia plan for this. |

|
|
Term
Describe physiology of diastolic dysfunction and what causes it |
|
Definition
Diastolic dysfunction occurs when your left ventricle is stiff / possible from hypertrophy and can no longer relax as easily during distole. As a result there is decrease compliance and when blood passively enters the ventricle it meets higher resistance. Therefore there is more pressure during diastole, hence why we call this increase filling pressures. Overall the period known as diastole is in dysfunction becasue the heart cannot relax normally and allow blood to passively flow normally.
Diastolic dysfuction is normally caused by disease that force the left ventricle to get bigger which eventually leads to a dysfunction in diastole. The LV gets bigger when theres incrase Afterload from stenotic valves, or HTN. |

It does not have side effects of salivation and it preserves spontaneous breathing. Once induction parameters are met, give your paralytic and then intubate |

what are the four main objectives of maintenance of anesthesia |
|
Definition
1. amnesia 2. analgesia 3. skeletal muscle relaxation 4. control of SNS to noxious stimulation |

what are three types of neuraxial regional anesthetic |
|
Definition
1. spinal 2. epidural 3. caudal |
|
|
Term
why is spinal better than epidural? What are the disadvantages of spinals |
|
Definition
Advantage of spinal: 1. takes less time to perform 2. produces more rapid onset and better quality of effect 3. is associated with less pain during surgery
Disadvantages: 1. postspinal headache 2. risks of intrathecal in arachnoid space. |
