研究目的: |
本研究旨在比较高频振荡通气(HFOV)与常规机械通气(CMV)在早产儿肺出血中的治疗效果,重点评估氧合改善情况,同时观察肺出血时间、支气管肺发育不良、死亡率等次要结局。通过前瞻性随机对照试验,以明确更优的机械通气策略。研究结果将为优化肺出血患儿的通气治疗提供高质量证据,改善临床预后,推动新生儿肺出血治疗的规范化和个体化发展。 |

|
Objectives of Study: |
This study aims to compare the therapeutic efficacy of high-frequency oscillatory ventilation (HFOV) versus conventional mechanical ventilation (CMV) in preterm infants with pulmonary hemorrhage, with a primary focus on oxygenation improvement. Secondary outcomes include duration of pulmonary hemorrhage, bronchopulmonary dysplasia (BPD), mortality, and other relevant measures. Through a prospective, randomized controlled trial (RCT), we seek to determine the optimal mechanical ventilation strategy for this high-risk population. The findings will provide high-quality evidence to optimize ventilatory management in neonates with pulmonary hemorrhage, ultimately improving clinical outcomes and advancing standardized, individualized treatment protocols for this critical condition. |

纳入标准: |
1.早产儿,即胎龄< 37周。 2.患儿需要有创机械通气。 3.临床诊断为肺出血,除外因气管插管损伤或其他创伤导致的气管内血性分泌物。 |
||||||||||||||||||||||
|
Inclusion criteria |
1.Preterm infants, defined as gestational age < 37 weeks. 2.Requirement for invasive mechanical ventilation. 3.Clinical diagnosis of pulmonary hemorrhage, excluding bloody tracheal secretions caused by endotracheal tube injury or other traumatic etiologies. |
||||||||||||||||||||||
|
排除标准: |
1.肺出血发生前使用过HFV。 2.存在严重先天性畸形、染色体异常或其他原发性肺部疾病(如先天性膈疝)。 3.在肺出血发生前已诊断为3/4级脑室内出血(IVH)的患者。 4.患者的监护人签署并拒绝参与试验,该患者将不会被纳入。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1.Use of HFV (High-Frequency Ventilation) prior to the onset of pulmonary hemorrhage. 2.Presence of severe congenital malformations, chromosomal abnormalities, or other primary pulmonary diseases (e.g., congenital diaphragmatic hernia). 3.Patients diagnosed with Grade 3/4 intraventricular hemorrhage (IVH) before the occurrence of pulmonary hemorrhage. 4.Patients whose legal guardians refuse to provide consent for trial participation will be excluded. |

随机方法(请说明由何人用什么方法产生随机序列): |
由独立统计人员使用计算机随机数字生成程序(如SAS 9.4或R软件)按1:1比例生成随机分配序列,将符合条件的新生儿分为高频振荡通气(HFOV)组和常规机械通气(CMV)组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
An independent statistician used a computer-generated randomization program (such as SAS 9.4 or R software) to generate the allocation sequence in a 1:1 ratio, assigning eligible neonates to either the high-frequency oscillatory ventilation (HFOV) group or the conventional mechanical ventilation (CMV) group. |

|
盲法: |
在本试验中,由于干预措施的性质(HFOV与CMV的操作差异,无法对实施治疗的医务人员和患儿进行设盲。然而,为确保数据分析的客观性,实验数据分析者及最终统计分析人员将不参与患儿的诊疗过程,并对分组信息保持盲态。 |
|
Blinding: |
In this trial, due to the nature of the interventions (operational differences between HFOV and CMV), blinding of the treating medical staff and infants was not possible. However, to ensure the objectivity of data analysis, the experimental data analysts and final statistical analysts were not involved in the clinical management of the infants and remained blinded to the group allocation information. |
