Airway US in Predicting Difficult Pediatric Laryngoscopy

Condition(s) studied

Investigational drug(s) / intervention(s)

SonoSite™ S Series ultrasound: US measurements will be performed in the pre-operating room a , patients are placed in supine position with the head in a sniffing position on a surgical pillow and using the 15 MHz linear array transducer of the SonoSite™ S Series ultrasound in transverse position. A scan is made from the skin surface of the floor of the mouth to the trachea exerting the minimum possible pressure to identify the structures correctly.

Study summary

The hypothesis of this study is that ultrasound measurements may improve the preoperative detection of difficult laryngoscopy (DL) in pediatrics. The primary objective of this study will be to evaluate the usefulness for the prediction of a DL of five ultrasound measurements obtained from the neck skin to three structures of the upper airway (hyoid, epiglottis and anterior commissure of the vocal cords). Secondary objectives will include establishing, if possible, a cut-off point in these measurements; to compare these measures against the classic pre-intubation clinical screening tests.

Eligibility

Primary outcome measure(s)

• prediction of a Difficult laryngoscopy of five ultrasound measurements obtained from the neck skin to three structures of the upper airway (hyoid, epiglottis and anterior commissure of the vocal cords). — Preoperative
  To evaluate the accuracy of five ultrasound measurements obtained from the neck skin to three structures of the upper airway (hyoid, epiglottis and anterior commissure of the vocal cords). Namely the DSH, DSE, DSG, DSH+DSE, and DSH-DSE in prediction of difficult laryngoscopy.
