Defining the 'Sniffing Position" in Infants & Toddlers

Status Completed

Clinical Trial Summary

The "sniffing position" is widely accepted as a favorable position for direct laryngoscopy (DL) in both pediatric and adult patients. External anatomical markers are well documented to confirm proper 'sniffing position' in adults, but data on their use in the pediatric population is sparse. The investigators propose to define these markers in young children and investigate whether patients positioned using this standardized approach have better intubating conditions than those positioned randomly per the preference of the anesthesiologist.

Clinical Trial Description

The procedure of endotracheal intubation in adults and children is a continuum, and begins with proper head positioning prior to direct laryngoscopy (DL). It is an accepted paradigm that proper positioning optimizes intubating conditions, and decreases subsequent airway maneuvers and manipulation.

The sniffing position is an accepted airway positioning concept in pediatric airway management, and continues to be recommended by experts and textbooks in the field. Anatomical peculiarities such as the large head relative to the torso in infants and toddlers is assumed to put the head in proper position when gently extended. However, reproducible parameters to confirm optimal head positioning remain vague and unclear. In the absence of objective and measurable markers, practitioners position infants and toddlers according to their individual preferences, and as such the procedure lacks definition and objective clarity.

The investigators plan to recruit 40 healthy patients between the ages of 1 month - 48 months and randomize them to be positioned either according to a predetermined algorithm or positioned freely according to the provider's preference. Patients randomized to the intervention group will be positioned with the aim to horizontally align the external auditory meatus (EAM) with the sternal notch (SN).

In summary, the study aims to define the sniffing position for infants and toddlers using reproducible objective secondary markers, and investigate whether a systematic approach to positioning using such markers improves direct laryngoscopic outcomes in the young pediatric patient population. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
