Feasibility and Utility of Ultrasonography in Evaluation of Diaphragmatic Motion and Thickness in Indian Population
Journal Title: International Journal of Health Sciences and Research - Year 2017, Vol 7, Issue 5
Abstract
Introduction: A properly functioning diaphragm is necessary for lung aeration and survival. Various clinical conditions affect normal motion of the diaphragm. Fluoroscopy used to assess diaphragmatic motion requires ionizing radiation and patient transportation. It would be ideal and cost effective if sonography is used for evaluation of motion of the diaphragm. Objective: Present study aimed to evaluate feasibility & utility of ultrasonography in evaluation of diaphragmatic motion and diaphragmatic thickness. Material and Methods: Record of 60 healthy, adult men and women were analysed. Participants were examined in supine position. Diaphragmatic movements were measured through anterior sub-costal and sub-xiphoid approach by using M-mode sonography. Diaphragmatic thickness was measured through anterior-axillary sagital low intercostals approach by using B-mode sonography. Results: Out of 60 participants, 53%& 47% were women &men respectively. Average age (Mean± SD) was 32.4±10.1 years. BMI and respiratory rate were 15 – 32 Kg/m2 and 14 – 22 respectively. Motion of right & left hemi-diaphragm during quit, deep and Sniff breathing was 1.72±0.32 &1.85±0.45, 4.73±0.54 & 4.97±0.39 and 2.4±0.57& 2.7±0.5cms respectively. Average motion of right& left hemi diaphragm was positively correlated with BMI. Correlation coefficient was 0.08 &0.16 respectively. Average diaphragmatic thickness fraction was 32.6±7.2 percent. Difference in diaphragmatic thicknesses at inspiration & expiration was statistically significant (P<0.003). Discussion: Present study helps in defining diaphragmatic movement and thickness fraction which will be useful in diagnosis and prognostic follow up of diaphragmatic paralysis. Conclusion: Ultrasonography is useful in evaluating diaphragmatic motion and thickness in Indian population.
