Anesthesia and Cancer Flashcards

1
Q

What does cancer result from?

A
  • Accumulation of genetic mutations that causes dysregulation of cellular proliferation (alteration in DNA structure)
    • inherited traits
    • mutaiton of normal gene into an oncogene
    • inactivation of tumor suppressor gene (p53)
  • Fundamental cellular event in malignancy: alteration in DNA structure
  • immune surveillance destroys many malignant cells
    • HIV/immunosuppressant disrupt protective mechanism
  • Most cancers produce solid tumors

A
  • Sx- take out organs like whipple
  • high dose chemo instilled in abd for one hour
  • causes lots of tumor lysis and electolye disturbances
75
Q

Anesthesia management during endoscopy?

A
  • Sedation
  • GA- TIVA (propofol)<– if pt can’t respond to name, general anesthesia
    • natural airway- NC- 2/Chin lift
76
Q

Anesthesia concerns during laparoscopic procedures>

A
  • General ETT ?RSI?
  • Regional- epidural
  • Hypovolemia–> avoid drugs which cause hypotension and/or decrease doses
  • avoid N2O
  • Drugs that are protein bound –> lower doses if low protein lab value
  • anemia, lower MAC
  • Avoid metoclopramide wiht obstruciton - contraindication
77
Q

Anesthesia managment for laparotomy?

A
  • General? RSI? <– full stomach, opioid slowing stomach
  • Regional- epidrual
  • hypovolemia–> avoid drugs which cause hypotension
  • avoid n2o- distention of bowel
  • drugs that are protein bound–> lower doses if low protein
  • anemia, lower MAC
  • Avoid metoclopramide
  • laparotomy- muscle relaxation needed for retractors
    • utilize multimodal!!
  • blood transfusion during sx resection of colorectal cancers is associated with decrease in length of patient survivial

Q

What are some various procedures that can be performed for prostate ca?

A
  • Laparotomy- radical prostatectomy
    • lap or robotic
      • minimally invasive prostatectomy
  • cystoscopy-transurethral resection (TURP)
    • laser
  • Radiation therapy
    • external beam
    • implantation of radioactive seeds
79
Q

ANesthesia concerns for prostate ca surgery?

A
  • Surgery vs radiation rx
  • hormone therapy- for metaststic type
  • resistance to rx–> bone pain
  • chemotherapy- cyclophosphamide, 5FU, Cisplatin, doxorubicin- alone or in combo
  • High dose prednisone- subjective improvement
  • positioning: lateral, sometime steep t-berg
    • cognizant of pt eyes and vent changes
      • lots of blodo loss possible
  • when robot docked, pt needs to be completely paralyzed
80
Q

Anesthesia management for TURP?

A
  • General
  • Regional
    • epdiural
    • spinal
  • TURP- systemic absorption of irrigation fluid–> volume overload
    • not as big of concern now that we don’t use glycine
  • DIlutional hyponatremia a concern
  • regional anesthesia- allows assessment of neuro when hyponatremia is concern
  • Laser
    • general
    • eye prection, fire risk
    • regional
      • epidural
      • spinal
81
Q

Concerns for head/neck cancer sx?

A
  • Possibility of distorted airway anatomy
  • review imaging studies and develop plan
  • dysphagia–> increased risk for aspiration
  • ENT surgeon at bedside during induction
    • esp if airway concern
  • positioning- sometimes patients far away, need stellar IV
82
Q

Anesthesia management for diagnosit suspension laryngoscopy/scope

A
  • Fiberoptic rigid scope
    • general TIVA w ETT (large size)
    • jet ventilation
    • arms tucked
83
Q

Anesthesia management for neck dissection?

A
  • General
    • hold NDMR for nerve preservation
  • Radical neck disection
    • general with ETT (maybe awake, maybe trach at beginning)
    • Aline, 2 large bore IV, T&C, hold NDMR
  • General with ETT- oral vs nasal depends on sx exposure
    • impaired ROM and mouth opening- fiberoptic
      • dyspnea-upright positioning
      • tracheal compression concern- avoid NMV
    • Airway may be inaccessible during case
    • concern with ETT compression- use armored tube
    • trachea- tube connections/access to pull ETT and reconnect
84
Q

Postop consideraiton for head/neck surgery?

A
  • prevent PONV
    • must provide reassurance that measure will be taken to attempt to contorl PONV
  • Treatment PONV
    • anti emetics
    • anesthetic technique
    • adjuncts
