![]() The education module included TTE-related knowledge and matters needing attention, sedation-related knowledge and matters needing attention and so on. The content of WeChat guidance mainly included two parts: an education module and answering questions. After making an appointment for TTE, the medical staff instructed the patient’s parents to join the WeChat group and taught them to use WeChat correctly and skillfully. We began to use WeChat to guide parents of patients to prepare for TTE in December 2021. All patients were given 0.5 ml/kg 10% chloral hydrate before TTE. Parents were routinely asked to complete the STAI scale and the Patient Satisfaction Questionnaire-18 (PSQ-18) after the patient underwent TTE, and these data were collected and stored. The clinical data of 47 patients and the anxiety and satisfaction data of their parents who received preparation guidance before TTE via the routine educational brochure between September 2021 and November 2021 were retrospectively collected as a routine group. Through the electronic medical record system, we retrospectively collected the clinical data of 44 patients and the anxiety and satisfaction data of their parents who received WeChat preparation guidance before TTE between December 2021 and January 2022. The following exclusion criteria were used: (1) infants with CHD who underwent emergency TTE (2) infants with other congenital diseases and (3) family members of the patients refused to participate in the study. The following inclusion criteria were used: (1) infants with CHD who underwent TTE as an outpatient service and (2) family members who could easily use the internet and WeChat. Assuming a 10% drop-out rate, the total sample size was set as 88 (44 per group). Based on the differences in the State-Trait Anxiety Inventory (STAI) scores of parents from the pre-experiment and assuming that the alpha value was set at 0.05 with a power of 0.80, the required number of participants was calculated to be 40 in each group. This study was a retrospective study conducted in a children’s hospital. Additionally, all parents of the patients signed the consent form before participating in the study. The present study was approved by the ethics committee of our hospital and adhered to the tenets of the Declaration of Helsinki. We conducted this retrospective study to explore the effect of using WeChat to guide preparation before TTE on reducing anxiety and improving the satisfaction of parents of infants with CHD. It is very important to provide effective preparation guidance before TTE for parents of patients to improve the success rate of examination, reduce the anxiety of parents and improve their satisfaction with medical treatment. Because of the lack of knowledge of echocardiography and sedation, they are often unable to prepare well for the examination, which results in repeated sedation, repeated examination or even examination failure. Therefore, many families of patients feel very anxious about undergoing TTE. ![]() Due to inadequate preparation, sedation and TTE examination often fail, and parents usually have a fearful attitude toward the use of sedatives. Sedatives are routinely used in many centers for infant examination. However, infants and young children are often unable to cooperate in completing this examination. Comprehensive and accurate echocardiography results require the close cooperation of patients and doctors. With the development of echocardiography technology, most CHD treatment decisions have been made according to echocardiography results. Transthoracic echocardiography (TTE) is the most important examination to evaluate the condition of children with congenital heart disease (CHD).
