Immunocompromised: Airway Management and Endotracheal Intubation
Immunocompromised adaptation of: Securing the patient airway for ventilation, with adaptations for the lunar medical environment and limited post-procedure monitoring.
Indications
Respiratory failure, cardiac arrest, severe altered consciousness (GCS <8), airway protection, surgical anesthesia.
Contraindications
No absolute contraindications in life-threatening emergency. Relative: suspected cervical spine injury (perform with inline stabilization).
Equipment Required
Standard Equipment
Laryngoscope (direct or video), ETT (range of sizes), stylet, 10mL syringe, CO2 detector, BVM, oxygen, suction, securing tape.
Lunar Medical Bay Substitutions
Standard plus: Video laryngoscope highly preferred in lunar context (better visualization, less reliance on patient positioning that is difficult in 1/6g). Backup King LT or LMA (rescue airway for failed intubation). Surgical airway kit (cricothyrotomy). Portable capnography for continuous CO2 monitoring. Ventilator for ongoing management.
Procedure Steps
Pre-oxygenate 3 min. RSI medications (succinylcholine + etomidate or ketamine). Cricoid pressure. Direct laryngoscopy — visualize cords. Tube between cords. Inflate cuff. Confirm with CO2 detector, bilateral breath sounds, CXR.
Lunar Technique Modifications (1/6 Gravity)
POSITIONING: In 1/6g, patient will need to be strapped to a flat surface for intubation — free-floating patients cannot be intubated safely. Supine position with neck slightly extended. Assistant stabilizes head. Video laryngoscope preferred as it does not require perfect sniffing position. Cricothyrotomy kit immediately available for failed airway.
Telemedicine Guidance Points
Contact Earth Medical Relay (+1.3s delay) at these critical decision points:
Consult for elective intubation planning. Immediate contact if >2 failed attempts. Consult on ventilator management parameters.
Training Requirements
Medical officers: airway management certification. Annual simulation training. Surgical airway drills.
Possible Complications
Failed intubation, esophageal intubation, right mainstem bronchus intubation, pneumothorax.
