  Purpose
Diaphragmatic dysfunction (DD) is one of the main risk factors for post operative respiratory distress syndrome. Ultrasonography is a diagnosis tool for DD but few studies have been published. The aim of this prospective study is to compare the achievement of diaphragmatic function depending on the type of surgery (abdominal and head and neck surgery).

Condition Intervention
Diaphragmatic Dysfunction Procedure: Diaphragmatic amplitude measurement

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Comparative Ultrasonic Study of Post Operative Diaphragmatic Dysfunction in Abdominal and Head and Neck Surgery

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:
  • Comparison of diaphragmatic amplitude measured by M-Mode ultrasonography performed the day before and the day after surgery in 3 groups: laparoscopic abdominal surgery, abdominal surgery by laparotomy and head and neck surgery. [ Time Frame: two months ]

Secondary Outcome Measures:
  • All cause morbidity [ Time Frame: within the first 28 days after surgery ]

Enrollment: 43
Study Start Date: October 2012
Study Completion Date: August 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Abdominal laparoscopic surgery (C group) Procedure: Diaphragmatic amplitude measurement
Diaphragmatic amplitude is measured by M Mode ultrasonography the day before and after surgery
Experimental: Abdominal surgery by laparotomy (L group) Procedure: Diaphragmatic amplitude measurement
Diaphragmatic amplitude is measured by M Mode ultrasonography the day before and after surgery
Experimental: Head and neck surgery (O group) Procedure: Diaphragmatic amplitude measurement
Diaphragmatic amplitude is measured by M Mode ultrasonography the day before and after surgery
