Brief Summary

Nasal endotracheal intubation is a well-utilized and important endotracheal intubation route to allow good surgical access for operations involving the oral cavity. Despite its utility, there are potential complications from nasal endotracheal intubation including that of nasal bleeding, which in severe cases can impair the ability to complete the procedure. The most accepted conventional practice to decrease bleeding associated with nasal endotracheal intubation is to warm the nasal endotracheal tube prior to insertion. However, this technique still yields high rates of nasal bleeding. In 1979, correspondence by MacKinnon and Harrison in Anaesthesia described the use of a flexible urinary catheter (Foley catheter) telescoped onto the endotracheal tube tip to aid atraumatic insertion of the tube. This also served to ensure the tube was not contaminated internally by nasal secretions or blood. This has been more rigorously studied in two RCTs looking at this technique in children, but there has been no similar study in adults. This study aims to extend the evidence base of the use of this technique in adults. Our hypothesis is that the use of a flexible urinary catheter to telescopically aid nasal intubation will result in a significant decrease in the incidence and severity of nasal bleeding.

Outcome Measures

Primary Outcomes (1)

  • Incidence of nasal bleeding

    Defined as the presence of blood on a folded stack of two 4x4 inch gauze swabs to the posterior oropharynx after the confirmation of successful nasotracheal intubation

    10 minutes (must be assessed prior to surgical start as this may cause additional bleeding)

Secondary Outcomes (5)

  • Severity of bleeding

    10 minutes (must be assessed prior to surgical start as this may cause additional bleeding)

  • Time to successful intubation

    10 minutes

  • Number of attempts at intubation

    10 minutes

  • Incidence of requirement to suction blood from the oral cavity to facilitate intubation

    10 minutes

  • Incidence of significant postop nasal bleeding

    24 hours

Study Arms (2)

Foley-assisted

EXPERIMENTAL

The tip of the nasal endotracheal tube will be telescoped onto a 16g Foley catheter. If a ballooned catheter is used then the inflation port may be cut off prior to use. The catheter tip is then fed through the pre-selected primary nare, until the tip of the endotracheal tube is in the oropharynx. The catheter is then removed from the tip of the nasal endotracheal tube through the mouth and disposed of. If the nasal endotracheal tube is inappropriately sized, a half size above or below may be used. If difficult to pass, the anesthetist may opt to use the other side nare. Following this, the anesthetist will complete the rest of the intubation as usual.

Device: Foley catheter

Control

NO INTERVENTION

The endotracheal tube is passed through the pre-selected primary nare, until the tip of the endotracheal tube is in the oropharynx. If the nasal endotracheal tube is inappropriately sized, a half size above or below may be used. If difficult to pass, the anesthetist may choose to use the other side nare. Following this, the anesthetist will complete the rest of the intubation as usual.

Interventions

Using a 16G Foley catheter to cover the tip of the endotracheal tube as it passes through the nose. This is done in comparison to the standard practice of directly passing an endotracheal tube through the nose without a cover. Both groups use warmed endotracheal tubes and the use of topical vasoconstrictor (4 sprays of 0.1% xylometazoline to each nare).

PARTICIPANT, OUTCOMES ASSESSOR
Masking Details
The patient will be blinded to group allocation as they are anesthetised during the intervention procedure. The outcome assessor for the primary outcome (incidence of nasal bleeding) will also be blinded by inspecting the gauze swab for blood outside the patient's operating theatre. The care provider and investigator are unable to be blinded due to the nature of the intervention.
Purpose
PREVENTION
Intervention Model
PARALLEL
Model Details: Two parallel study groups allocated by randomization to either the intervention group (Foley-assisted nasal endotracheal intubation) or control (standard nasal endotracheal intubation). Randomisation is via sealed opaque numbered envelopes that are only opened to reveal group allocation once the patient has been recruited.
