The Cleveland Clinic
ClinicalTrials.gov Identifier:
NCT01289483
First received: January 31, 2011
Last updated: April 17, 2017
Last verified: April 2017
  Purpose

Patients scheduled for awake fiberoptic intubation (AFI) because of potential difficult airway will be consented prior to intubation ASA Physical Status classification and history of difficult intubation will be recorded at screening. The investigators will also record the results of airway examination including Mallampati classification, thyromental distance, mouth opening, neck circumference, neck range of motion, presence or absence of beard and overbite, history of neck radiation, and mandibular protrusion test Informed consent will be obtained prior to the procedure from those patients who meet the inclusion and exclusion criteria.

Standard hemodynamic monitoring will be used in all patients including EKG, blood pressure, heart rate, respiratory rate and oxygen saturation. Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale will be used to assess the level of alertness/sedation. Two consecutive MOAA/S scores of 4 will be considered as the desired effect of moderate sedation.

For AFI procedure, IV will be started and oxygen will be administered. 4 L of oxygen will be delivered through nasal canula until the completion of the AFI procedure. Patient head will be positioned in the sniffing position, Topical anesthesia would be achieved using the topical administration of 4 percent lidocaine using atomized and MaDgic nebulizer, and 2% xylocaine Jel applied to the surface of Williams airway in a total dose of lidocaine not exceeding 10 mg/kg. Patients will be randomized to one of the four fospropofol treatment arms: 2, 3.5, 5, or 6.5 mg/kg

Primary Outcome Measures:
  • Rescue intubation needed [ Time Frame: every 4 minutes during procedure, day 1 ]
    Requiring rescue midazolam and or fentanyl to facilitate intubation

  • Hypotension [ Time Frame: every 2 minutes, during procedure, day 1 ]
    Development of hypotension ( defined as blood pressure drop of more than >30 % of base line) and/or hypoxemia ( SaO2 < 90% or a drop of >5% of baseline , whichever is lower)


Secondary Outcome Measures:
  • hypertension [ Time Frame: every 2 minutes, during procedure day 1 ]
    Development of hypertension ( increase in blood pressure of > 30% of baseline), and/or tachycardia (120 beat/min or increase in heart rate of > 30% of base line, whichever is higher )

  • Total dose of midazolam and fentanyl used [ Time Frame: end of procedure, day 1 ]
    Total dose of midazolam and fentanyl used

  • ease of intubation [ Time Frame: seconds, after intubation, day 1 ]
    anesthesiologists' assessment of ease of intubation on a visual analog scale (VAS) of 0-10, with 0 being very easy, and 10 being very difficult.

  • Patient recall and satisfaction [ Time Frame: end of procedure,day 1 ]
    Patient recall and satisfaction

  • Time to intubate [ Time Frame: seconds, during procedure, day 1 ]
    Time to intubation ( first fospropofol bolus to positive EtCO2 )

  • Failed intubation [ Time Frame: seconds, day 1 ]
    Failed intubation

  • unresponsiveness [ Time Frame: seconds, during procedure, day 1 ]
    Patient becoming un-responsive and /or requiring bag-mask Ventilation
