The purpose of this study is to determine whether verification of correct tube placement after endotracheal intubation in the obese patient can be conducted as fast with ultrasound as with the conventional method of combined auscultation and capnography.

The investigators hypothesize that ultrasound is a faster method for verifying correct endotracheal tube placement in the obese patient than combined auscultation and capnography.

Further study details as provided by Bispebjerg Hospital:

Primary Outcome Measures:
  • Difference in time to correct verification of endotracheal tube placement between ultrasound and combined auscultation and capnography [ Time Frame: 0 to 1 hour ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Difference in time to correct verification of endotracheal tube placement between ultrasound and auscultation alone [ Time Frame: 0 to 1 hour ] [ Designated as safety issue: No ]

Estimated Enrollment: 24
Study Start Date: October 2010
Groups/Cohorts Assigned Interventions
Obese patients for planned surgery and endotracheal intubation Device: Ultrasound
Ultrasound scan just proximal to the suprasternal notch during intubation and ultrasound scan of both lungs during ventilation

Detailed Description:

Both verification methods are conducted in all patients and patients act as their own control
