纳入标准:

入选为研究人群必须同时满足以下几个条件: (1)2022年12月1日至2023年12月1日在我院小儿外科中心入院手术的复杂右心病变患儿; (2)具体病种:为减少病种异质性对临床结果的影响,本研究拟纳入的病种为常见复杂右心病变,具体包括重度 TOF 及 TOF 型 DORV、 PAA/VSD、肺动脉外管道狭窄; (3)具体手术方式为体外循环下根治术、姑息性右室肺动脉连接术或外管道狭窄再置换术; (4)年龄在 6 月-14周岁之间; (5)患儿父母或法定监护人及具有一定自主决定权的患儿自愿签署知情同意书。

Inclusion criteria

To be included in the study population, the following conditions must be met at the same time: (1) children with complex right heart disease admitted to the Pediatric Surgery Center of our hospital from December 1, 2022 to December 1, 2023; (2) Specific diseases: In order to reduce the impact of disease heterogeneity on clinical outcomes, the diseases to be included in this study are common complex right heart lesions, including severe TOF and TOF DORV, PAA/VSD, and extrapulmonary stenosis; (3) The specific surgical methods were radical operation under extracorporeal circulation, palliative right ventricle-pulmonary artery connection or re-replacement of external conduit stenosis; (4) The age was between 6 months and 14 years old; (5) The parents or legal guardians of the children and the children with certain autonomy signed the informed consent voluntarily.

排除标准:

​术中已经给予ECMO支持者;术后返ICU前发现已经出现肢体末端微栓、缺血紫斑者;入组后发现残存心脏解剖畸形;存在膈肌麻痹;存在严重的气道狭窄或软化者;同期行气道成形手术者;合并其它系统严重病变或畸形。以上当中出现任何一项即可排除。

Exclusion criteria:

Patients with ECMO support during the operation; microemboli and ischemic purpura were found in the extremities before returning to ICU after the operation; residual cardiac malformation was found after operation; diaphragmatic paralysis was found; severe airway stenosis or malacia was found; tracheoplasty was performed at the same time of cardiac repair; severe lesions or malformations of other systems were found.Any of the above can be excluded.

干预措施:

测量SVRI<1200并且在2h内补充等张液体≥30ml、VIS≥20、通过超声评估除外解剖残余畸形和严重心功能低下(LVEF≤40%)的情况下仍然存在低血压状态,才使用血管加压素

干预措施代码:

Intervention:

Vasopressin was used when SVRI < 1200, isomeric fluid >=30, VIS>=20 within 2h, and hypotension remained after ultrasound assessment except for anatomic residual malformation and severe cardiac hypofunction (LVEF<=40%)
