Further study details as provided by Mingkwan Wongyingsinn, MD, Siriraj Hospital:

Primary Outcome Measures:
  • The overall intubation duration [ Time Frame: Participants will be followed for the overall intubation duration until confirmation the endotracheal position, an expected average of 2 minutes ]
    The overall intubation duration is recorded on the decision to intubation patient and corresponds to the time of confirmation the endotracheal position by chest auscultation

Secondary Outcome Measures:
  • the intubation duration [ Time Frame: Participants will be followed for the intubation duration until confirmation the endotracheal position, an expected average of 5 minutes ]
    The intubation duration (Ti), it is defined from application the laryngoscope into the patient's mouth to the time of confirmation an endotracheal position

  • Complication [ Time Frame: Participants will be followed in the period of staying in the emergency room and hospital, an expected average of 4 weeks ]
    Complications occur during and after intubation peroid are recorded and monitored until patients are discharged fromt the hospital.

Enrollment: 224

Study Completion Date: December 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: RSI technique

Intubation with RSI technique. RSI technique includes the administration of inductive and neuromuscular blocking agents to facilitate an intubation.

In this study, we have no restriction of medication use. Physicians can chose any of medication as an individual judgement.

Drug: RSI

All medications are administered only one dose before intubation


Propofol 2-2.5 mg/kg Thiopental 3-5mg/kg Etomidate 1-2mg/kg

Neuromuscular blocking agents:

Succinylcholine 1-1.5mg/kg Rocuronium 0.9mg/kg


Fentanyl 1-2ug/kg

Other Name: Rapid Sequence Intubation
No Intervention: Non-RSI
Intubation without RSI technique. No any medication use during intubation period.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:
