Lecture 2: Intraoperative procedures Flashcards
What is the universal protocol for pre-op marking?
- Verify pt name, DOB, and procedure
- Mark operative site with a signature (not an X)
- Time out in OR prior to beginning procedure
How long is an H&P good for (in regards to surgery)?
30 days
I wrote this in so its not actually on the slides lol just 5
What occurs day of surgery in Pre-op?
- Check in
- Holding room to chart and check
- Anesthesiologist confirms surgery and anesthesia type
- Surgeon marks surgery site via universal protocol
What occurs in the operating room initially?
- Apply monitors
- Anesthesia induction
- O2 mask
- IV Drugs (opiods as “pre-treatment” agents)
- Anesthetic agonist (decreases HTN response during intubation)
What are the anesthesia induction agents? and their side effects
- Propofol (diprivan) = rapid onset, pain at injection site
- Ketamine = CNS effects, hallucincations
Propofol=makes your Pressure FOll…get it??? foll,…drops BP (enochs trick)
Ketamine makes u KraZYyY (also enochs)
What is the MC muscle relaxant/neuromuscular blocker/paralytic for anesthesia?
Succinylcholine, except if you have malignant hyperthermia
Can cause postop myalgia
Which anesthetic is usually used in children?
isoflurane
This is an inhaled anesthetic
What is malignant hyperthermia?
- Pharmacogenetic disorder of skeletal muscle, as a hypermetabolic response to anesthesia.
- Characterized by hyperthermia, tachycardia, tachypnea, increased O2 consumption, cyanosis, cardiac dysrhythmias, metabolic acidosis, respiratory acidosis, muscle rigidity
Cannot use Succ or fluranes if a patient has this response!
How is malignant hyperthermia treated?
- Dantrolene (prevent release of calcium)
- O2
- Body cooling/fluids
- Supportive care
If personal/FHx, flushing of anesthesia machine is done prior.
What 4 signs suggest malignant hyperthermia?
- Unexplained tachycardia
- Increased end tital CO2
- Increased body temp (above 38.8C)
- Masseter rigidity
What two agents can someone with malignant hyperthermia not use for anesthesia?
- No inhaled anesthesia gases (-Fluranes)
- No depolarizing muscle relaxants (Succinylcholine)
Describe the process of anesthesia induction.
- Preparation
- Preoxygenation 5 mins prior
- Pretreatment 3 mins prior
- Paralysis
- Protection 30 after
- Placement of ET tube 45s after
- Post-intubation management 60s after
What can be done if an airway is difficult?
- Cricoid pressure
- Fiberoptic laryngoscope
- GlideScope
How is intubation placement confirmed?
Auscultation/condensation in tube
What are the 4 types of anesthesia?
- Conscious sedation/MAC
- Regional
- General
- Combined regional & general
