Brief Summary

Inability to provide oxygen to the patient remains the most fearful anesthesia-related mishap. Cricothyrotomy (CT) is an infrequently performed but life saving procedure for an anesthesiologist, who is encountered with this situation. The current method of cricothyrotomy relies on digital palpation (DP). Several patient populations, including morbidly obese, short neck, radiation to and previous neck surgeries, have difficult landmarks for this procedure. Ultrasound (US) technology has been used in the past to visualize landmarks for cricothyrotomy, but there is no study which has examined the role of ultrasound in patients who have obscure landmarks. There is no data related to the performance of ultrasound guided cricothyrotomy in these patients. In this study, we aimed to determine the outcomes of CT performed on human cadavers using US-guidance, compared to conventional DP, of anatomical landmarks. In particularly, complication rates, failure to cannulate, correct placement of the device and insertion time of CT were assessed.

Outcome Measures

Primary Outcomes (1)

  • The Primary Outcome Measure Was the Complication Rate Asssed as the Number of Participants Causing Injuries

    The primary outcome measure was the complication rate as assessed by the severity of injuries; defined as the incidence and severity of posterior laryngeal and tracheal wall injuries, as graded by two anesthesiologists using the grading system described by Murphy et al,( none (no injury); mild (\< 5 mm laceration); moderate (\> 5mm laceration or partial puncture); severe (\> 10 mm laceration or full puncture)).

    On avergae less than 300 seconds

Secondary Outcomes (3)

  • Insertion Time

    less than 5 minutes from starting of procedure

  • Number of Attempts

    not more than 300 seconds

  • Correct Landmarking

    less than 300 seconds
