To compare average time to successful intubation and success rates using direct laryngoscopy (DL) with those using a battery-operated videoscope (VS) in uncomplicated manikin intubations.
Forty-four paramedics and emergency medicine faculty and residents received training with DL and VS. Participants performed 3 timed trials using each device. A single group repeated-measures analysis of variance for average time measurements was performed.
Grouping physicians and paramedics, mean time to successful intubation for DL was 14.6 seconds (SD, 4.3 seconds) and for VS was 25.9 seconds (SD, 9.2 seconds; P < .001). All attempts were successful with both devices. A secondary measure compared intubation times for physicians and paramedics on both devices. For DL, mean time to successful intubation for physicians was 13.2 seconds (SD, 3.8 seconds) and for paramedics, 15.9 seconds (SD, 4.3 seconds; P > .43). For VS, mean time for physicians was 26.0 seconds (SD, 10.0 seconds) and for paramedics, 25.7 seconds (SD, 8.6 seconds; P > .43).
Intubation with DL in uncomplicated manikin airways was faster than with VS (P < .001). Success rates were equal.
比较在简单的人体模型插管操作中,使用直接喉镜(DL)与使用电池供电的视频喉镜(VS)实现成功插管的平均时间和成功率。
44名护理人员、急诊医学教员和住院医师接受了DL和VS的培训。参与者使用每种设备进行3次计时试验。对平均时间测量进行单组重复测量方差分析。
将医生和护理人员分组,DL成功插管的平均时间为14.6秒(标准差,4.3秒),VS为25.9秒(标准差,9.2秒;P <.001)。两种设备的所有尝试均成功。第二项测量比较了医生和护理人员在两种设备上的插管时间。对于DL,医生成功插管的平均时间为13.2秒(标准差,3.8秒),护理人员为15.9秒(标准差,4.3秒;P >.43)。对于VS,医生的平均时间为26.0秒(标准差,10.0秒),护理人员为25.7秒(标准差,8.6秒;P >.43)。
在简单的人体模型气道中,使用DL插管比使用VS更快(P <.001)。成功率相同。
