Q

Once in Operating Room, how to prepare for Anesthesia?

A

●Apply monitors (BP, O2 sat, EKG leads, temp strip)
● Anesthesia induction (General Anesthesia) - Amnesia, Analgesia, Muscle relaxation, and Sedation
● O2 mask
● IV Drug Administration
- Opioids - “Pretreatment” Agents
- Fentanyl
● Anesthetic agonist: Decreases HTN response during intubation

What is Malignant Hyperthermia?

A

A pharmacogenetic disorder of skeletal muscle that presents as a hypermetabolic response to potent volatile anesthetic gases

Q

Anesthesia Induction

A
  • Preparation 10 mins before
  • Preoxygenation 5 mins before intubation
  • Pretreatment 3 mins before induction
  • Paralysis with agent
  • Protection 30 seconds after induction
  • Placement of ET Tube 45 seconds after induction
  • Post-intubation Management 60 seconds after intubation
17
Q

what 3 things can help with ET intubation if it is a difficult airway?

A
  • Application of cricoid pressure
  • Fiberoptic laryngoscope
  • GlideScope
18
Q

Once Endotracheal tube is inserted, what are the next steps?

A
  • Inflate bulb on tube to secure airway
  • Connect to O2
  • Confirm placement of tube by auscultation of lungs/condensation in the tube
  • Tape in place
19
Q

complications of ET intubation

A
  • Damage to teeth, soft tissue of mouth/pharynx, lips
  • Tachycardia, BP irregularities
  • Laryngospasm on extubating
20
Q

Types of Intraoperative Anesthesia is Dependant on several factors:

A
  1. patient’s medical history,
  2. the surgical procedure that is to be performed,
  3. the preference of the surgeon and anesthesiologist, and
  4. the patient’s first choice.
21
Q

4 Types of Anesthesia

A
  1. General Anesthesia
  2. Conscious Sedation or Monitored Anesthesia Care (MAC)
  3. Regional Blocks
  4. Local anesthesia
22
Q
  • Monitored, without intubation
  • Medications Commonly Used: Propofol, Fentanyl, Versed
  • Common with Endoscopies
    which type of anesthesia
A

Monitored Anesthesia Care (MAC) or Conscious Sedation

23
Q
  • Common with invasive surgeries of the extremities, or below the waist pelvic surgery (C-section, bladder sling)
  • Common Medications - Lidocaine, Bupivacaine
    what type of anesthesia
A

Spinal and Epidural

24
Q

how to inject for Spinal anesthesia

A
  • Lumbar Level (L3-L4)
  • Enter subarachnoid space, inject anesthetic into CSF
25
how to inject for epidural anesthesia
* Any point in vertebral column * Inject anesthetic into epidural space
26
Proper Positioning for spinal ansthesia
* Lateral Decubitus * Sitting, bending forward
27
SE of spinal anesthesia
* HA * Most Serious - Cauda Equina Syndrome * Hypotension, Sedation, Respiratory Depression, Infection (Abscess)
28
which has less potential SE, spinal or epidural anesthesia?
Epidural - Less potential for side effects still has Hypotension, Sedation, Respiratory Depression, Infection (Abscess)
29
CI for spinal/epidural anesthesia
Back abnormalities and infections
30
agents for local anesthesia
Lidocaine (with/without Epinephrine), Bupivacaine
31
Should not use Epinephrine local anesthesia on where of the body
distal end points Penis, nose, fingers and toes
32
how to prepare/inject for local anesthesia
1. Skin cleaned and prepped first 1. Inject Deep & Superficial around surgical site 1. Use caution not to inject into vasculature
33
local anesthesia is common for what types of procedures
1. Common for minor skin procedures 1. Commonly used to control postoperative incisional pain 1. Digital Blocks
34
How to Prevent injury to patient when positioning a pt
Provide padding with towels or gel pads Heels, elbows, wrists, under knees, neck
35
why avoid malpositioning of arms and legs
Can result in nerve injury - ie - brachial plexus or ulnar nerve injury
36
how to position pt for surgery
* Proper positioning for surgical procedure * Prevent injury to patient * Avoid malpositioning of arms and legs * During operation, avoid leaning on patient * Cover exposed body parts not in the operative field with warm blankets - May use bear hugger. * Apply ground pads to skin out of the operative field
37
what preparation must be performed using sterile technique (Performed by circulating OR-RN)
Skin Prep
38
what solutions to use for skin prep
Chlorhexidine Betadine Hibiclens Alcohol Multiple Application Methods: Sponges, Stick Applicator
39
Proper Way to Gown and Glove
1. Remove jewelry (rings, bracelets, dangling earrings) - Remember: Fingernails short, nail polish without chips (No acrylic) 2. Put on protective equipment - Haircover and facial hair/sideburn cover - Shoe Covers - Mask - Eyewear 3. Gather all supplies in OR - Gown, Gloves - Open using sterile technique 1. Scrub 1. Enter OR 1. Dry off with sterile towel 1. Don sterile gown + gloves
