This is a prospective, comparative, randomized, monocentric, clinical open study, to compare two anesthesia techniques (translaryngeal injection vs. spray as you go) in patients with cervical instability with regard to technical modalities and quality of fiberoptic awake intubation.

Condition Intervention
Intubation Procedure: awake intubation

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Official Title: Anesthesia for Awake Fiberoptic Intubation in Patients With Cervical Instability - Comparison of Translaryngeal Injection and "Spray as You go"-Technique

Primary Outcome Measures:
  • patients satisfaction with anesthesia [ Time Frame: up to two weeks after hospital admission ]
    participants will be followed for the duration of hospital stay, an expected average of 2 weeks

Secondary Outcome Measures:
  • pain after anesthesia [ Time Frame: Change from Baseline in pain after anesthesia at end of hospital stay ]

Enrollment: 120
Study Start Date: January 2009
Study Completion Date: January 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: translaryngeal injection
translaryngeal injection of local anesthetics before the awake intubation
Procedure: awake intubation
two anesthesia techniques
Active Comparator: spray as you go
local anesthetics are given through the fiberoptic during awake intubation
Procedure: awake intubation
two anesthesia techniques

Detailed Description:

In patients with cervical instability anesthesia induction and conventional intubation are associated with the risk of neurological harm. Therefore the method of choice for anesthesia induction is the fiberoptic awake intubation. This method allows to place the ventilation tube without movement of the cervical spinal cord. This procedure is very uncomfortable for the patient and needs the application of topic and/or systemic anesthetics.

With this clinical study we will compare two established techniques for local laryngeal anesthesia with regard to the quality of technical modalities and postoperative outcome.
