We assessed whether a short training, effective in a high resource country, was able to improve the quality of face-mask ventilation (FMV) in a low resource setting.
Local healthcare providers at the Centre Médico-Social, Kouvè, Togo were asked to ventilate a neonatal leak-free manikin before (time-t1) and after (t2) a two-minute training session. Immediately after this section, a further two-minute training with participants aware of the data monitor was offered. Finally, a third 1-minute FMV round (t3) was performed by each participant. Ventilatory parameters were recorded using a computerized system. Primary outcome was the percentage of breaths with relevant mask leak (>25%). Secondary outcomes were percentages of breaths with a low peak inspiratory pressure (PIP<20 cm H2O), within the recommended PIP (20-35 cm H2O) and with a high PIP (>35 cm H2O).
Twenty-six subjects participated in the study. The percentage of relevant mask leak significantly decreased (p<0.0001; β = -0.76, SE = 0.10) from 89.7% (SD 21.5%) at t1 to 45.4% (SD 27.2%) at t2 and to 18.3% (SD 20.1%) at t3. The percentage of breaths within the recommended PIP significantly increased (p<0.0001; β = +0.54, SE = 0.12). The percentage of breaths with PIP>35 cm H2O was 19.5% (SD 32.8%) at t1 and 39.2% (SD 37.7%) at t2 (padj = 0.27; β = +0.61, SE = 0.36) and significantly decreased (padj = 0.01; β = -1.61, SE = 0.55) to 6.0% (SD 15.4%) at t3.
A 2-minute training on FMV, effective in a high resource country, had a positive effect also in a low resource setting. FMV performance further improved after an extra 2-minute verbal recall plus real time feedback. Although the training was extended, it still does not cost much time and effort. Further studies are needed to establish if these basic skills are transferred in real patients and if they are maintained over time.
我们评估了在资源丰富国家有效的短期培训,是否能够在资源匮乏环境中提高面罩通气(FMV)质量。
多哥库韦医疗社会中心的当地医疗服务提供者在两分钟培训课程之前(时间t1)和之后(t2)对无泄漏新生儿人体模型进行通气。在这一部分之后,立即为参与者提供了另外两分钟的培训,参与者可以看到数据监测器。最后,每位参与者进行第三轮1分钟的FMV(t3)。使用计算机系统记录通气参数。主要结局是存在相关面罩泄漏(>25%)的呼吸百分比。次要结局是吸气峰压低(PIP<20 cm H2O)、吸气峰压在推荐范围内(20 - 35 cm H2O)以及吸气峰压高(>35 cm H2O)的呼吸百分比。
26名受试者参与了该研究。相关面罩泄漏的百分比显著降低(p<0.0001;β = -0.76,SE = 0.10),从t1时的89.7%(标准差21.5%)降至t2时的45.4%(标准差27.2%),并在t3时降至18.3%(标准差20.1%)。吸气峰压在推荐范围内的呼吸百分比显著增加(p<0.0001;β = +0.54,SE = 0.12)。吸气峰压>35 cm H2O的呼吸百分比在t1时为19.5%(标准差32.8%),在t2时为39.2%(标准差37.7%)(校正p值 = 0.27;β = +0.61,SE = 0.36),并在t3时显著降低(校正p值 = 0.01;β = -1.61,SE = 0.55)至6.0%(标准差15.4%)。
在资源丰富国家有效的两分钟FMV培训,在资源匮乏环境中也产生了积极效果。额外两分钟的口头回顾加实时反馈后,FMV表现进一步改善。虽然培训时间延长了,但仍然没有花费太多时间和精力。需要进一步研究来确定这些基本技能是否能在实际患者中得以应用,以及是否能长期保持。
