Endotracheal Intubation Using Three Laryngoscopes in Maternal Cardiac Arrest: a Manikin Simulation Study

European Resuscitation Council (ERC) Guidelines for Resuscitation 2010 emphasize high quality chest compressions .They propose minor changes for pregnant women: manual left deviation of the uterus or a left-lateral incline of 15-30to alleviate pressure on the inferior vena cava. We will examine the performance of the Glidescope (GVL), the Pentax-AWS Airwayscope(AWS) and Macintosh laryngoscope (McL) for airway management during chest compressions on 15 and 30 degree left-lateral tilt (15 &30 LLT) custom-made hard wedges.

About this study

Materials

  • Sim Mom manikin (Laerdal, Stavanger, Norway)
  • Stryker ST104-747(Transport stretcher®, 760 x 2110 mm, 228 kg, Stryker Co., Kalamazoo, Michigan, US)
  • LUCAS Chest Compression System( LUCAS Chest Compression System, Physio-Control/Jolife AB)
  • Backboard(450 ×600 ×10 mm, 3 kg Lifeline Plastic, Sung Shim Medical Co., Bucheon, Korea)

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Experience of intubation > 50 times
  • Postgraduates year 1,2,3,4 and Emergency physicians in emergency department

Exclusion criteria

  • Wrist or Low back disease

Treatment and study plan

15 degree left-lateral tilt wedges

Device

The wedges are made of aluminium

Other names: Custom-made hard wedges

30 degree left-lateral tilt wedges

Device

The wedges are made of aluminium

Other names: Custom-made hard wedges

Primary outcomes

  1. Time to intubation

    Time frame: 1day

    We will check the times from inserting blade to mouth to exposing vocal cord and from exposing vocal cord to first ambu-bagging.

  2. Success rate of intubation

    Time frame: 1day

    Definition of failed intubation

    • Time to intubation is longer than 90 seconds.
    • Wrong placement of endotracheal tube (For example : Esophageal intubation etc.)

Secondary outcomes

  1. Laryngeal View during intubation

    Time frame: 1day

    We will record the best laryngeal View during intubation. We will record according to the Cormack-Lehane Grade system.

  2. The preference for laryngoscopes

    Time frame: 1day

    • The preference for laryngoscope regardless of tilting degree of wedges
    • The preference for laryngoscope in 15 degree left-lateral tilt situation .
    • The preference for laryngoscope in 30 degree left-lateral tilt situation . (Participants will select only 1 of 3 laryngoscopes and the preference will be displayed as histogram)
