To evaluate the use of newborn resuscitation timelines to assess the incidence, sequence, timing, duration of and response to resuscitative interventions. A population–based observational study conducted June 2019–November 2021 at Stavanger University Hospital, Norway. Parents consented to participation antenatally. Newborns ≥28 weeks’ gestation receiving positive pressure ventilation (PPV) at birth were enrolled. Time of birth was registered. Dry-electrode electrocardiogram was applied as soon as possible after birth and used to measure heart rate continuously during resuscitation. Newborn resuscitation timelines were generated from analysis of video recordings. Of 7466 newborns ≥28 weeks’ gestation, 289 (3.9%) received PPV. Of these, 182 had the resuscitation captured on video, and were included. Two-thirds were apnoeic, and one-third were breathing ineffectively at the commencement of PPV. PPV was started at median (quartiles) 72 (44, 141) seconds after birth and continued for 135 (68, 236) seconds. The ventilation fraction, defined as the proportion of time from first to last inflation during which PPV was provided, was 85%. Interruption in ventilation was most frequently caused by mask repositioning and auscultation. Suctioning was performed in 35% of newborns, in 95% of cases after the initiation of PPV. PPV was commenced within 60 s of birth in 49% of apnoeic and 12% of ineffectively breathing newborns, respectively. Newborn resuscitation timelines can graphically present accurate, time-sensitive and complex data from resuscitations synchronised in time. Timelines can be used to enhance understanding of resuscitation events in data-guided quality improvement initiatives.

新生儿复苏时间表：准确捕捉产房内的治疗情况

评估新生儿复苏时间表的使用，以评估复苏干预的发生率、顺序、时间、持续时间和反应。 2019 年 6 月至 2021 年 11 月在挪威斯塔万格大学医院进行的一项基于人群的观察性研究。父母同意产前参与。纳入出生时接受正压通气（PPV）的妊娠≥28周的新生儿。出生时间已登记。出生后尽快应用干电极心电图，并在复苏过程中连续测量心率。新生儿复苏时间表是根据视频记录分析生成的。在 7466 名妊娠 ≥ 28 周的新生儿中，289 名 (3.9%) 接受了 PPV。其中，182 人的复苏过程被拍摄成视频，并被纳入其中。三分之二的人出现呼吸暂停，三分之一的人在 PPV 开始时呼吸无效。 PPV 在出生后中位（四分位数）72 (44, 141) 秒开始，持续 135 (68, 236) 秒。通气分数（定义为提供 PPV 期间从第一次充气到最后一次充气的时间比例）为 85%。通气中断最常见的原因是面罩重新定位和听诊。 35% 的新生儿进行了抽吸，95% 的病例在开始 PPV 后进行了抽吸。分别有 49% 的呼吸暂停新生儿和 12% 的呼吸困难新生儿在出生后 60 秒内开始 PPV。新生儿复苏时间线可以以图形方式呈现及时同步的复苏的准确、时间敏感且复杂的数据。时间表可用于增强对数据引导的质量改进计划中的复苏事件的理解。
