Laryngoscopy in space travel.

F E LeJeune

    The Annals of Otology, Rhinology, and Laryngology
    |November 1, 1979
    PubMed
    Summary

    Astronauts may need laryngoscopy during long space missions. A modified laryngoscope and coaxial technique are proposed to help inexperienced users perform this procedure in microgravity.

    The Laryngoscope·1997

    Area of Science:

    • Aerospace Medicine
    • Medical Devices
    • Surgical Procedures

    Background:

    • Long-duration spaceflight necessitates onboard medical capabilities.
    • Astronauts may face challenges performing medical procedures due to inexperience and microgravity.
    • Laryngoscopy is a critical procedure that may be required in space.

    Purpose of the Study:

    • To address the anticipated need for laryngoscopy during long space missions.
    • To consider the challenges faced by inexperienced endoscopists in a microgravity environment.
    • To propose a simplified technique and modified device for space-based laryngoscopy.

    Main Methods:

    • Development of a simplified coaxial intubation technique.
    • Modification of a Jako-type laryngoscope for ease of use in space.
    • Consideration of the unique challenges of the free-floating space environment.

    Main Results:

    • A simplified coaxial intubation technique is proposed.
    • A split-apart modification of a Jako-type laryngoscope is suggested.
    • The proposed method aims to mitigate challenges of inexperience and microgravity.

    Conclusions:

    • The modified laryngoscope and coaxial technique offer a potential solution for in-flight laryngoscopy.
    • This approach could enhance the safety and efficacy of medical procedures in space.
    • Further development and testing are warranted for space mission readiness.
