Primary Outcome Measures:
  • The rate of intubation success (the percentage of patients for whom intubation was successful) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]

    - The primary endpoint is the rate of intubation success (the percentage of patients for whom intubation was successful). A success is defined as intubation achieved in less than four attempts.

    Patient is either considered a success or failure. Number of Intubation Attempts (following the guidelines of ASA) is a maximum of three attempts after which patient will be considered a failure



Secondary Outcome Measures:
  • The mean duration of induction (in seconds) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    The mean duration of induction (in seconds) defined as the time required to reach a Ramsay score of 5 from start of induction

  • The mean duration of intubation procedure (in minutes) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    The mean duration of intubation procedure (in minutes) defined as the time from intubation start to the completion of the intubation process(from tube introduction to PETCO2)

  • Percentage of patients who experienced complications resulting from intubation procedure [ Time Frame: Day 1 ] [ Designated as safety issue: Yes ]
    Percentage of patients who experienced complications resulting from intubation procedure (including but not limited to: bleeding, salivating, lung aspiration)

  • Percentage of patients who experienced difficulties related to the use of sevoflurane [ Time Frame: Day 1 ] [ Designated as safety issue: Yes ]
    Percentage of patients who experienced difficulties related to the use of sevoflurane (including but not limited to: vocal cords adduction, coughing, movements, apnea episodes)

  • The mean number of intubation attempts [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    The mean number of intubation attempts


Estimated Enrollment: 97

Estimated Study Completion Date: October 2013
Estimated Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts
DTI patients
Male or non pregnant female over 18 years who are undergoing surgery and using sevoflurane as the anesthetic agent with Mallampati score III or IV

Detailed Description:

This study aims to evaluate the effectiveness of sevoflurane in intubation in Egyptian, non obstetric patients undergoing surgery who suffer from suspected difficult intubation.

The study will collect clinical data from approximately 97 difficult to intubation patients who has been administered sevoflurane during anesthesia induction in the operating room. The intubation success rate and duration of intubation will be calculated.

Criteria

Inclusion Criteria:

  5. Neoplasms; e.g., laryngeal tumors
  6. Rheumatoid arthritis - TMJ immobility
  7. Diabetes mellitus
  8. Waxy skin - palm test
