High peak inspiratory pressure (PIP) and tidal volume (V(T)) from manual ventilation are hazardous to the neonatal lung. We investigated the influence of operator training on the extent of applied PIP and V(T) between two manual ventilation devices. We performed a prospective, crossover study of 84 medical professionals using a neonatal mannequin. Participants were classified into four groups, according to experience in neonatal resuscitation and previous training in manual ventilation. Provision of PIP, V(T), and inspiratory time (Ti) were compared between groups and equipment used, either a self-inflating bag (SI-bag) or a T-piece resuscitator (Neopuff). Using SI-bags, operator training significantly affected provision of PIP ( P < 0.001), V(T) ( P < 0.001), and Ti ( P = 0.048). Using a T-piece device, PIP and V(T) provision was independent of operator training ( P = 0.55 and P = 0.66, respectively). Twenty-five participants (30%) had previous experience with T-piece devices; this correlated significantly with lower PIP and lower V(T) provision ( P > 0.001 for PIP and V(T)). Operator training level and device-specific experience had a significant impact on PIP and V(T) provision when using SI-bags for manual ventilation. For operators with no specific training in manual ventilation, use of T-piece devices is advised to control for excessive PIP and V(T) application.
高吸气峰压(PIP)和潮气量(V(T))会对新生儿肺部造成损害。我们研究了操作人员培训对两种手动通气设备应用的 PIP 和 V(T) 程度的影响。我们使用新生儿模型对 84 名医疗专业人员进行了前瞻性、交叉研究。根据新生儿复苏经验和手动通气的先前培训,参与者分为四组。在设备使用方面,无论是自主充气袋(SI-bag)还是 T 型复苏器(Neopuff),比较组间和组内的 PIP、V(T)和吸气时间(Ti)的提供情况。使用 SI-bags,操作人员培训显著影响 PIP(P < 0.001)、V(T)(P < 0.001)和 Ti(P = 0.048)的提供。使用 T 型设备时,操作人员培训对 PIP 和 V(T) 的提供没有影响(P = 0.55 和 P = 0.66)。25 名参与者(30%)有使用 T 型设备的经验,这与较低的 PIP 和 V(T) 提供显著相关(P < 0.001)。在使用 SI-bag 进行手动通气时,操作人员培训水平和设备特定经验对 PIP 和 V(T) 的提供有显著影响。对于没有接受过手动通气特定培训的操作人员,建议使用 T 型设备以控制过高的 PIP 和 V(T) 应用。
