Effect of Nose Selection Using Rhnoscope on Epistaxis of Nasotracheal Intubation

Rhinoscope is useful to exam intranasal structure. This information could be utilized to select more suitable nose for nasotracheal intubation. Nastoracheal intubation using more patent nose could be associated with decrease of the development of epistaxis which is most common complication in nasotracheal intubation.

About this study

Anterior rhinoscopy using rhinoscope is a simple way to view the intranasal structure, which allows you to observe the nasal mucosa, the inferior nasal concha, and in some cases, the nasal concha. You can see the nasal septum, polyps, and intranasal malformations. In addition, even when there are no structural abnormalities in the nasal cavity, the wider nasal cavity can be intuitively identified. This information is expected to assist in the selection of nostrils. It has not yet been studied whether anesthesiologists select nasal cavity for nasotracheal intubation using prosthesis can affect the occurrence of epistaxis.

The purpose of this study is to determine whether the selection of a nostril for nasotracheal intubation by rhinoscope affects the incidence and severity of epistaxis.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • ASA I or II undergoing surgery under nasotracheal intubation

Exclusion criteria

  • expected difficult intubation based on history, physical examination, weight.
  • bleeding tendency
  • past history of nasal surgery
  • symptom of difficulty of nasal respiration

Treatment and study plan

rhinoscope

Diagnostic Test

more suitable nose for nasotracheal intubation will be selected based on the view of rhinoscope.

Primary outcomes

  1. incidence of epistaxis

    Time frame: immediate after intubation

    percentage of the development of epistaxis after nasotracheal intubation

  2. incidence of epistaxis

    Time frame: 5 min after intubation

    percentage of the development of epistaxis after nasotracheal intubation

Secondary outcomes

  1. severity of epistaxis4. severe: interfere intubation by blood

    Time frame: immediate after intubation

    score based on severity of epistaxis will be recorded.

    1: no epistaxis, 2: mild; blood on tube 3. moderate: blood pooling on pharynx

  2. severity of epistaxis

    Time frame: 5 min after intubation

    score based on severity of epistaxis will be recorded.

    1: no epistaxis, 2: mild; blood on tube 3. moderate: blood pooling on pharynx
