Name, concentration, date, time, & initials
DAMITS Airway
Laryngoscope handles & blades x2 each MAC & Miller *Check/replace lightbulbs or batteries Water-soluble lubricant Tongue blade 4x4s Various size oral/nasal airways x2 Soft bite block Appropriate patient size ETT 7.0/7.5/8.0 LMAs 3/4/5 Check cuff - 10cc syringe to inflate Stylet Face mask AMBU bag Video laryngoscope (back-up airway) Bougie or adjuncts Difficult airway & malignant hyperthermia carts
Machine/Monitors/Masks
Anesthesia gas machine check EKG, BP cuff, Pox, ETCO2 Peripheral nerve stimulator Set appropriate alarms Calibration Appropriate size mask - Simple face mask, non-rebreather, or NC Transport tank w/ O2
DAMITS IV
Alcohol, tourniquet, catheter, tape/tegaderm Stopcock(s) Lidocaine syringe IV fluids & warmer Arterial line - Pressure bag Blood tubing Place 2nd IV after induction Verify IV patent & easily accessible
Tape/Tubes/Temp
Wipe machine down prior to placing tape on surface Pre-tear tape w/ tab (easier to find edge) - Eyes - Secure ETT/LMA *Ask preceptor tape preferences OG/NG Temp probe - esophageal (core) or skin Bair hugger
SUCTION
ON HIGH @ HOB
DAMITS Other
Clamps Stethoscope- precordial Peripheral nerve stimulator Bair hugger & fluid warmer Eye protection/face shield Laryngotracheal topicalization anesthesia LTA BIS (bispectral index) monitor Wire cutters
Induction
Attach monitors SUCTION Pre-oxygenate/de-nitrogenate Time out Fentanyl & Lidocaine Sweep monitors Place nerve stimulator Adjust bed height Fit for anesthesia Ensure everything w/in reach Induction medications Confirm unconscious - check lash reflex Baseline TOF Paralytic (standard) Bag-mask ventilate Tape eyes Re-check TOF INTUBATE
Adequate Ventilation S/S
Bilateral breath sounds
Chest rise & fall
Fogging/condensation in mask or ETT
Continuous ETCO2
After Intubation
Verify placement Check appropriate ventilator settings Switch to vent mode ↓flows Turn on anesthetic gas Secure the airway Re-position Place temp probe & OG tube Additional IV or A-line Admin antibiotics
RSI
Full stomach Violated NPO guidelines Obesity Pregnant >14wks Cirrhosis ↑abdominal pressure GERD, bowel obstruction, gastroparesis Do NOT mask-ventilate Apply cricoid pressure as induction agent admin & maintain until ETT placement confirmed
Failure to Emerge
Residual NMB
Excessive opioid or benzo (reversal agent)
Intraop CVA
Pre-existing pathophysiologic condition - CNS disorder, hepatic insufficiency, ETOH ingestion
Electrolyte abnormalities
Acidosis
Hypothermia
MAC
Monitored Anesthesia Care
Patient spontaneously breathes & able to protect own airway
NO muscle relaxant
Monitoring & supplies set up for general anesthesia
Always prepare for advanced airway management
*Consider positioning - ease to manipulate, access, & control airway
Difficult airway in inaccessible position not appropriate
VIGILENCE
MAC Drugs
Versed
Opioids - Fentanyl, Remifentanil, Alfentanil, Morphine → respiratory depression
Propofol (sedative-hypnotic)
Ketorolac, Ketamine, Clonidine, Dexmedetomidine
Potential MACs
Pacemaker insertion Burr hole Simple GYN Cataract Hernia Urological Skin & breast Arthroscopic
MAC Failure
Inadequate local anesthetic
Painful position
Uncooperative patient - pediatrics or psych
Paradoxical sedation effects
Stages of Anesthesia
- Analgesia & amnesia
- Delirium & excitation
- Surgical anesthesia (plane 2)
- Overdose (medullary depression)
