Filter by:The aim of this study is to evaluate the appropriateness of the two kinds of nasotracheal tube (PORTEX POLAR [Smiths Medical International, Hythe, United Kingdom], Mallinckrodt TaperGuard [Covidien, Ireland]) depth in neutral, extended and flexed neck position when the upper border of the cuff of endotracheal tube is located 3cm below the vocal cords in neutral neck position.
Nasotracheal intubation (NTI) is commonly used in operations of the mouth, pharynx, larynx and also the neck .Various complications can occur such as epistaxis, bacteremia,turbinectomy, retropharyngeal dissection, and nasal alar pressure sores or necrosis.In clinical practice, nasal pressure sores caused by NTI are not uncommon, but have failed to attract clinical attention.The investigators have observed that the surgeon fixed the nasal tracheal tube and threaded tube directly to the patient's head. The investigators suspect that this method can reduce the pressure between the nasal tube and the nose.
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.
Nasotracheal intubation(NTI) is commonly used in operations of the mouth, pharynx, larynx and also the neck. While these patients showed higher rates of difficult laryngoscopy. Therefore, duration of apnoea is prolonged and re-oxygenation is inevitable.Mask ventilation is the most fundamental technique in maintaining oxygenation, even when endotracheal intubation is failed. However, the most common complication of NTI is epistaxis, removing the nasotracheal tube could make mask ventilation extremely difficult.So the investigatorsbelieve the ideal approach is ventilation through original nasotracheal tube.Several techniques of supraglottic ventilations through endotracheal tubes have been reported.It remains uncertain whether supraglottic ventilation through inflated nasal RAE endotracheal tube has similar efficiency as mask ventilation after general anesthesia induction. Based on previous clinical experience, the investigators hypothesised that ventilations through inflated nasal RAE endotracheal tube and through facemask were comparable in terms of tidal volume and airway pressure in anesthetized, apnoeic adults. Forty patients were randomly assigned (sealed envelope method) to face mask（Group A，n=20）or nasal ventilation(Group B，n=20), For A: face mask ventilation followed by nasal ventilation and for B:nasal ventilation followed by face mask ventilation.Measure the tidal volume and air leakage of face mask and nasal ventilation during pressure-controlled ventilation mode and volume-controlled mode, respectively.
After Ethics committee approval investigators decided to enroll 40 patients ASA I-II, 18-60 years of age undergoing maxillofascial, oral and double chin surgery to determine which nostril is more suitable for nasotracheal intubation with nasotracheal Airtraq. We primay aimed to compare the glottis visualization time, intubation time and total intubation times.
Epistaxis or post-pharyngeal bleeding is the most common complication after nasotracheal intubation (NTI). Prior thermal softening of the endotracheal tube (ET) has been recommended as one of the methods to prevent nasal trauma from nasotracheal intubation. However, thermal softening of tubes tends to adversely affect the nasotracheal navigation of the ET. During NTI under conventional direct laryngoscopy, the tip of the Macintosh laryngoscope is advanced into the vallecula, indirectly elevating the epiglottis by applying pressure on the hyoepiglottic ligament. Although this maneuver allows optimal visualization of the glottis, it lifts the larynx away from the tip of the advancing nasotracheal tube (NTT), which generally lies along the posterior pharyngeal wall. Most clinicians use Magill forceps to direct the tip of the NTT anteriorly to enter the glottis. Magill forceps may cause damage to the cuff of an ET or may injure oropharyngeal mucosa. The use of a video laryngoscope and a cuff inflation technique has been proposed as a method for reducing the malalignment of tubes. Indirect laryngoscopy using a Video laryngoscopy can reduce malalignment by minimizing lifting the glottis during laryngoscopy. The cuff inflation technique (wherein the cuff of ET tube is inflated with 15 mL of air) has been used while performing "blind" NTI to guide such malaligned polyvinyl chloride (PVC) ET tubes into the laryngeal inlet. Recently, one study reported that the cuff inflation technique consistently improved the oropharyngeal insertion of the different ET tubes of varying stiffness during direct laryngoscope-guided NTI. There has never been study about effect of cuff inflation technique on navigability when performing NTI under video laryngoscopy guidance with ET tubes of varying stiffness.Investigators assessed and compared the incidence of nasal injury and nasotracheal navigability with two technique during cuff inflation-supplemented NTI guided by video- laryngoscopy
To investigate the double curve endotracheal tube safely navigate through nasal cavity under guidance of a video-stylet.
to investigate the effectiveness of techniques of either using Magill forceps or cuff inflation in facilitation of nasotracheal tube advancement into trachea
to compare either using conventional jaw thrust technique or with a novel fingers-hook technique to facilitate video-stylet assisted nasotracheal intubation
The aim of study was to compare the hemodynamic responses and adverse events associated with nasotracheal intubation (NTI) using a fiberoptic bronchoscope (FOB) and a direct laryngoscope (DLS) in children undergoing general anesthesia for outpatient dental surgery. Eighty children (aged 5-15 years) were scheduled to undergo outpatient dental surgery under general anesthesia and who required nasotracheal intubation were included.
