Outcome Measures

Primary Outcomes (4)

  • The efficacy of the LMA Supreme device as assessed by measurement of ventilation on Case Report Form 1

    Outcome being measured intraoperatively is the ease of manual ventilation via the LMA Supreme. Measuring, no air leaks, air leak / elevated airway pressure needed for adequate ventilation, removal and reinsertion needed to achieve adequate ventilation, no ventilation after 2 attempts (airway managed using alternative techniques

    Intraoperative

  • The efficacy of the LMA Supreme device as assessed by measurement of ease of swallowing on Case Report Form 2

    Outcome being measured preoperatively and at 4 weeks +/- 5 days is the Dysphagia (difficulty swallowing) Short Questionnaire. Measuring the ability to swallow (any difficulty in swallowing), incorrect swallowing (any coughing associated with swallowing), lump feeling (any lumps in the throat), involuntary loss of weight (any weight loss recently), Pneumonia (any bouts with pneumonia).

    Preoperative and up to 4 weeks (+/- 5 days) postoperative

  • The efficacy of the LMA Supreme device as assessed by measurement of removal of the LMA Supreme Device on Case Report Form 1

    Outcome being measured intraoperatively is any blood on the LMA upon removal. Measuring if there is minimal or no blood, blood covering less than one fourth of the LMA or blood on at least one half of the LMA surface.

    Intraoperative

  • The efficacy of the LMA Supreme device as assessed by measurement of any intraoperative episodes developing reporting outcomes on Case Report Form 1

    Outcome being measured intraoperatively is did patient develop any intraoperative episodes of laryngospasm, hiccups, or coughing.

    Intraoperative

Secondary Outcomes (1)

  • Dysphagia Short Questionnaire

    Preoperative and up to 4 weeks postoperative (+/- 5 days).

Study Arms (1)

Observational: LMA Supreme

An appropriately sized LMA Supreme will be prepared by removing all air from the cuff while applying manual pressure. A water soluble non-local anesthetic containing lubricant gel will be applied to the fully deflated airway before insertion. A 1 cm column of the gel will be preloaded into the gastric port of the LMA Supreme for the Gel Test. The cuff will be inflated with a manometer to a pressure of approximately 30cm H2O. If a significant leak is detected, the cuff will be inflated in increments of 5cm H2O until a satisfactory seal is obtained. The final cuff pressure will be recorded. The lungs will then be gently inflated by applying manual pressure to the anesthesia circuit bag while observing the gel column in the LMA Supreme gastric port for movement.

Device: LMA Supreme

Interventions

Placement of the LMA Supreme supraglottic airway device for patients undergoing outpatient spine surgery in the prone position.

Observational: LMA Supreme

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Patients undergoing outpatient spine surgery in the prone position that meet the eligibility criteria.

You may qualify if:

  • to 70 years of age
  • American Society of Anesthesiology Classification (ASA) I-III patients
  • Fasting for 8 hours
  • Scheduled surgery with indication for laryngeal mask airway

You may not qualify if:

  • Unable to safely position themselves prone with assistance
  • History of previous failed LMA Supreme placement
  • BMI greater than or equal to 53
  • Inability to comply with study requirements including follow-up
