Conditions
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.
Interventions
Placement of the LMA Supreme supraglottic airway device for patients undergoing outpatient spine surgery in the prone position.
Eligibility Criteria
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:
- Have contraindicating conditions
- Have had radiotherapy to the neck involving the hypopharynx (risk of trauma, failure to seal effectively).
- Have inadequate mouth opening to permit insertion
- History of hiatal hernia
- Scheduled for minimally invasive spine stabilization procedures such as Transforaminal Lumbar Interbody Fusion (TLIF), Anterior Cervical Discectomy and Fusion (ACDF) (all have neuromonitoring/general endotracheal intubation)
- Scheduled for Joimax procedure (initial anesthetic is MAC)
- 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
