  Purpose
This investigation was designed to assess the patency of the esophageal entrance during cricoid pressure (CP) in anesthetized, paralyzed obese and non obese patients using the Glidescope ® video laryngoscope (GVL).

Condition Intervention
Aspiration Other: cricoid pressure

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Prevention
Official Title: Efficacy of Cricoid Pressure in Occluding the Esophageal Entrance: A Glidescope ® Study

Further study details as provided by Ahed ZEIDAN, Procare Riaya Hospital:

Primary Outcome Measures:
  • Efficacy of Cricoid Pressure for Prevention of Aspiration [ Time Frame: 24 hours ]

Enrollment: 89
Study Start Date: January 2011
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: obese patient Other: cricoid pressure
The current study test by direct visual evidence the occlusion of esophageal entrance during application CP. The closure of the lumen was further demonstrated by the inability to introduce a GT into the esophagus during CP.
Other Name: Glidescope
Experimental: non obese patient Other: cricoid pressure
The current study test by direct visual evidence the occlusion of esophageal entrance during application CP. The closure of the lumen was further demonstrated by the inability to introduce a GT into the esophagus during CP.
Other Name: Glidescope

Detailed Description:
Eighty-nine patients undergoing surgeries necessitating general anesthesia and tracheal intubation were enrolled in this study. Group 1 (OB) including obese patients (n= 59) was undergoing bariatric surgery. Following rapid sequence induction/intubation (RSII) anesthesia with cricoid pressure, clear view of the vocals cord and the entrance to the esophagus were assessed using Glidescope® video laryngoscope before intubation and following intubation. Following securing the airway, efficacy of cricoid pressure was tested by the capability to insert gastric tubes (20 and 38 Fr) under direct vision using GVL. Group 2 (NOB) including non-obese patients (n=30) was undergoing moderate surgery requiring tracheal intubation under general anesthesia. Efficacy of cricoid pressure was also tested similarly using GT's (20 and 38 Fr) following induction of anesthesia and before intubation. Inability of GT insertion was recorded as non-patent esophagus (effective CP) and successful insertion of GT was recorded as patent esophagus (ineffective CP). Then CP was released and insertion of GT achieved for correct verification of the esophageal opening position in both groups.
