17
Q
PROCEDURES
OPTHALMIC
-duration
-blood loss
-outpt or inpt
-blocks & for what
-drugs
-atropine for...
A
  • short
  • minimal
  • retrobulbar / peribulbar - anesthesia/ akenesia
  • outpatient
  • fentanyl, midazolam, propofol
  • to treat oculocardiac reflex
18
Q
PROCEDURES
OPTHALMIC
-why thorough pre-op necessary
-why explain plan to pt
-which drug should be used in caution in ederly patients
-bed position
-what drug is needed for block placement
-why LESS IS MORE
A
  • ederly pts w/ significant med history
  • to avoid intra-op anxiety w/ minimal sedation
  • midazolam
  • 90 degress so ensure efficient airway before sedation & draping
  • propofol bolus
  • no movement tolerated & therefore less sedation = more pt awareness = prevention of involuntary movements
19
Q
PROCEDURES
OPTHALMIC
PRECAUTIONS (3)
-explain OCR
-avoid\_\_ since may take 4 hrs
-why need to treat hypoxia early
A
  • caused by traction on extraocular muscles or putting pressure on eyeball
  • consists of trigeminal afferent and vagal efferent pathway
  • present as bradyc, vent ectopy, sinus arrest
  • Tx=stop or atropine (10mcg/kg)
  • excess of fluid to prevent bladder distention
  • b/c there will be decrease in lung reserve due to decreased tidal volumes under sedation
20
Q
PROCEDURES
ORTHOPEDIC
-sedation done in conjunction with ...
-drugs used
-if block adequate then use...
-if block inadequate then use...
-what is best kinds of agents for manipulation (closed reductions) & how give them
A
  • regional/local blocks
  • fentanyl, midazolam, propofol
  • propofol drip at low doses
  • narcotics
  • small boluses fo short acting agents
21
Q
PROCEDURES
ORTHOPEDIC
PRECAUTIONS
-what consider when release tournaquet
-what side effects monitor
-what need to continually check
-what need to have all equipment ready for
A
  • tournaquet pain and effect of lactic acid release
  • blocks (phrenic nerve block, high spinal)
  • position of pt, esp during fracture reductions where pulling & manipulation
  • GA
22
Q
PROCEDURES
GENERAL SURGERY / ENDOSCOPY
-how long
-what need to provide for pt
-drugs
-what need to do prior to administration of sedation
A
  • short - so need short acting agents
  • pt comfort while minimizing pt mvment
  • fentanyl, midazolam, propofol(drip)
  • pt in position
23
Q
PROCEDURES
GENERAL SURGERY / ENDOSCOPY
PRECAUTIONS
-what are pts at high risk for
-why need thorough medical history
-what about GYN procedures
-what need to have all equipment ready for
A
  • aspiration during endoscopy due to underlying disease & insulflation of air/fluids into stomach
  • pts receiving a G/J tube or would debridement often have a complicated / acute / long-term health hisotry & may be taking other synergistic meds
  • will be sedated in same manner but may require narcotics
  • GA
24
Q
PROCEDURES
PLASTICS
-drugs
-what need to secure
-what kind of pre-op info need from pt
A
  • fentanyl, midazolam, propofol

Q
PROCEDURES
PLASTICS
PRECAUTIONS
-ensure good candidate for... b/c...
-what kind of agents use & why
-why consider using anti-emetics

  • MAC b/c access to face/airway may be very limited including post-op care
  • short acting meds b/c procedure may be short
  • to avoid strain on sutures during vomiting
26
Q
PROCEDURES
MRI/CT SCAN

-what may need to be repeated if procedure is interrupted
A
  • midazolam, propofol (drip)
  • anxiety & comfort during lengthy CT scans/nosie of MRI
  • safe & efficient airway
  • secure safe & efficient airway
27
Q
PROCEDURES
MRI/CT SCAN
PRECAUTIONS
-tubing
-monitors
-equipment ready for
A

28
Q
PROCEDURES
ENT
-drugs

-equipment ready if 
-why need extra bolus of meds
-why coach pt to cough
-why suction during procedure
-why consider antiemetics
A
  • fentanyl, midazolam, propofol
  • airway
  • difficult airway
  • more than one direct laryngoscopy may be peformed by surgeons
  • possible post-op blood in airway
  • to avoid aspiration if heavily sedated
  • blood swallowed may cause N/V
29
Q
PROCEDURES
PAIN
-drugs
-what need to note during med history
-why need to consult with surgeon
- why need pt in position necessary for procedure prior to sedation
A
  • fentanyl, midazolam, propofol
  • when last took pain meds, dose, & next dose
  • if pt needs to give verbal feedback during procedure
  • to ensure comfort & relief of position associated pain
30
