干预措施:

采用改良Dixon序贯法确定环泊酚抑制胃镜置入反应的剂量。环泊酚初始剂量为0.4mg/kg,剂量梯度为0.04 mg/kg,如果前一例患儿为阳性反应,则下一例患儿环泊酚剂量增加1个剂量梯度;如果前一例为阴性反应,则下一例患儿降低1个剂量梯度。

干预措施代码:

Intervention:

Using an improved Dixon sequential method to determine the dose of cyclosporine that inhibits gastroscopy placement response. The initial dose of cyclosporine is 0.4mg/kg, with a dose gradient of 0.04 mg/kg. If the previous child has a positive reaction, the dose of cyclosporine in the next child will be increased by one dose gradient; If the previous case has a negative reaction, the next case will have one dose gradient reduced.
