<fentanyl (Sublimaze)
sufentanil (Sufenta)
meperidine (Demerol)
morphinen sulfate (Statex)>
<How are opioids used as adjuncts to general anesthesia?>
<reduced dosages are used for older clients, clients with a circulatory problem (ex: heart failure) and debilitated clients)>
<What are the effects of opiods as adjuncts to general anesthesia?>
<*provides pain relief AFTER
surgery
*DEPRESSES RESPIRATION>
<What is the potency relationship between Fentanyl and Morphine?>
<Fentanyl is 75 to 125 times more potent than Morphine>
<Define balanced anesthesia?>
<a combination of IV drugs and inhalation agents used to obtain specific effects>
<What is balanced anesthesia used for?> (haamr)
<to provide:
amnesia
analgesia
hypnosis
muscle relaxation
reduced reflexes with
minimal disturbance of
physiologic function>
<When is balanced anesthesia most advantageous?>
<provides safe and controlled anesthetic delivery, especially for older and high-risk clients>
<What are some balanced anesthesia combinations?>
<*thiopental for induction
*nitrous oxide for amnesia
*morphine for analgesia
*pancuronium for muscle
relaxation>
<What systems are affected by general anesthesia?>
<cardiac
GI
kidney
muscles
respiratory
skin: incision>
<Undesirable outcomes of surgery include?>
<*bleeding
*fluid and electrolytes are
out of balance which is due
to large amounts of IV
fluids
*inflammation process>
<How does positioning put the patient at risk perioperatively?>
<*Poor body positioning puts patient at risk for pressure ulcer formation.
*Good body positioning can prevent obstruction of circulation, respiration, and nerve conduction.>
<Common surgical positions include?>
< dorsal recum. (mostcommon)
*jackknife
*lateral
*lithotomy (mostcommon)
*prone (mostcommon)
*supine
*trendelenburg>
How is padding used when positioning patients for surgery?
Circulating nurse pads, coordintes transfer to OR bed, assessing skin integrity, and adds extra padding as needed.
Factors influencing TIMING of repositioning of patient by circulating nurse on OR table?
age and size
anesthetic delivery
pain on movement if client
conscious
surgical site
Factors influencing ACTUAL position of repositioning of patient by circulating nurse
include?
age, size, and weight
any pulmonary, skeletal, or
muscular limitations, such
as arthritis, joint
replacements, or emphysema
specific procedure being
performed
surgeon's request
<Surgical patient's skin can be impaired. Nursing interventions for this include?>
(3 at skin level
1 at body level)
<*plastic adhesive drape
*skin closures, sutures,
staples, nonabsorbable
sutures
*insertion of drains
*application of dressing
*transfer of client from the
operating room table to a
stretcher>
Define absorbable sutures?
*digested over time by body enzymes
*catgut, plain gut and chromic gut are types of natural absorbable sutures
*natural and synthetic absorbable sutures are absorbed in about 2 weeks
