Efficacy Of Sonographic Measurement Of Laryngeal Air Column Width And Laryngeal Air Column Difference For Predicting Post Extubation Stridor in neurosurgical patients.

Post extubation stridor is a respiratory complication after removal of endotracheal tube.Ultrasound measured laryngeal air column width difference has emerged as non invasive technique with promising results in predicting  post extubation stridor.Planing to conduct an observational study on efficacy of sonograghic measurement of laryngeal aircolumn width and laryngeal air column difference for predicting post extubation stridor in neurosurgical patients as unique risk factors for post extubation stridor due to lower cranial handling,pinning of head and positioning is there in neurosurgical patients.
