■气道超声已越来越多地用于气管内导管的正确定位。我们假设在超声的帮助下可以实现气管导管尖端和隆突之间的安全距离。
■我们的主要目的是确定与传统方法相比,超声引导下气管导管套囊近端的可视化效果是否更好。次要目标是在成年印度人口中找到切牙水平的最佳气管导管位置。
■常规组和超声组各25例。常规方法包括听诊和呼气末二氧化碳描记术。在超声组中,气管内导管套箍的上端被定位,旨在提供从管尖端到隆突的4cm距离。两组均使用X线片确认头端位置,并进行两组间的比较。如果有指示,则进行管的进一步重新定位,然后测量切牙处的管的平均长度。
■X射线确认后,USG组24%的患者和常规组40%的患者需要气管导管重新定位。然而,这一结果没有统计学意义(p=0.364).女性牙齿水平的气管导管长度为19.4±1.35cm,男性为20.95±1.37cm。
■超声检查是确定气管中ETT位置的可靠方法。与常规方法相比,差异无统计学意义。门牙水平的ETT平均长度女性为19.5厘米,男性为21厘米。
UNASSIGNED: Airway ultrasound has been increasingly used in correct positioning of
endotracheal tube. We hypothesize that a safe distance between
endotracheal tube tip and carina can be achieved with the aid of ultrasound.
UNASSIGNED: Our primary objective was to determine whether ultrasound guided visualisation of proximal end of endotracheal tube cuff is better when compared to conventional method in optimal positioning of tube tip. The secondary objective was to find the optimal
endotracheal tube position at the level of incisors in adult Indian population.
UNASSIGNED: There were 25 patients each in the conventional group and the ultrasound group. Conventional method includes auscultation and end tidal capnography. In the ultrasound group the upper end of the
endotracheal tube cuff was positioned with an intent to provide 4 cm distance from the tube tip to the carina. X ray was used in both groups for confirmation of tip position and comparison between the two groups. Further repositioning of the tube was done if indicated and the mean length of the tube at incisors was then measured.
UNASSIGNED: After x ray confirmation,
endotracheal tube repositioning was required in 24% of patients in the USG group and 40 % of patients in the conventional group. However, this result was not found to be statistically significant (p = 0.364). The endotracheal tube length at the level of teeth was 19.4 ± 1.35 cm among females and 20.95 ± 1.37 cm among males.
UNASSIGNED: Ultrasonography is a reliable method to determine ETT position in the trachea. There was no statistically significant difference when compared to the conventional method. The average length of ETT at the level of incisors was 19.5 cm for females and 21 cm for males.
