Assessment of a Properly Video Stylet Angulation for Nasotracheal Intubation
Studieoversigt
Status
Betingelser
Detaljeret beskrivelse
In oro-maxillo-facial surgery, it is a common practice for patients receiving general anesthesia with nasotracheal intubation to widen the surgical field and to ease undergoing surgery. However, a nasotracheal tube blindly passing through the nasal cavity may easily result in nasal cavity and oropharynx damages.
The aim of the study is to investigate use which angulation including 45 degree, 70 degree and 90 degree is appropriate to assist the nasotracheal tube passing the nasal cavity, oropharynx, and advanced into the tracheal. Patients are randomized into three groups by 45 degree, 70 degree and 90 degree to facilitate nasotracheal tube sliding through into trachea and compared with each other group.
Hemodynamic changes in each time interval, each time taken of tube going through the nasal cavity, tube advanced from oropharynx into trachea will be recorded. The incidence of using the video stylet with different angulation to accurately place tube tip into trachea, intubation related side effects and complications are recorded at postoperative time stages.

vurdering af svær intubation (IDS)
Tidsramme: Under proceduren
|
Vurdering af vanskelig intubation efter intubationssværhedsskala (The Intubation Difficulty Scale, IDS, 1997) er påkrævet efter intubation.
Antal forsøg>1, score "N1"; Antal operatører >1, score "N2"; Antal alternative teknikker, score "N3"; Comark Grade -1, score "N4"; Løftekraft påkrævet Normal, score "N5=0"; Løftekraft påkrævet Øget, score "N5=1"; Larynxtryk Ikke anvendt, score "N6=0"; Larynxtryk påført, score "N6=1"; Vocal Cord Mobility Abducion, score "N7=0"; Vocal Cord Mobility Adducion, score "N7=1".
IDS=Summen af score(N1-N7).
Hvis IDS-score stiger "0" betyder "Nem", "0<IDS≤5" betyder "Lille vanskeligheder", "5<IDS" betyder "Moderat til Større vanskeligheder", "IDS=∞" betyder "Umulig intubation".

vurdering af Glottisk karakter (Cormack Grade)
Tidsramme: Under proceduren
|
Vurdering af glottisk karakter (Cormack Grade) er påkrævet efter intubation.
Definitionerne af karakter: Grad 1: fuld visning af glottis; Grad 2a: delvist billede af glottis; Grad 2b: Kun arytenoider; Grad 3: Kun epiglottis; Grad 4: hverken glottis eller epiglottis identificeret

post-intubation induceret oropharyngeal blødning, hæshed og ondt i halsen
Tidsramme: Dag 2 (dagen efter operationen)
|
Et besøgsspørgeskema bruges til at måle tilstanden af post-intubation, herunder orofaryngeal blødning, ondt i halsen, hæshed, dysfagi.
Scoren for måling af orofaryngeal blødning, ondt i halsen, hæshed, dysfagi er opdelt i fire grader: ingen, mild, moderat og svær.
Hele evalueringen vil blive vurderet den næste morgen efter postoperationen.
