选择32例出生3小时内的新生儿分别行传统法及侧入法插管,每法16例,以比较两法之优劣。选择10名具有脐动脉插管经验平均3.5年的护士行两种插管术。幅度1.5～10年其中7名常规使用传统法,3名用侧入法。患儿在暖箱中,同时监测心率、呼吸、血压、氧饱和度。患儿肢体固定,腹部备皮,在脐带上打结以控制出血。根据新生儿大小选择3.5或5.0号导管,插管接三通管使管内肝素化。传统法为在近端1cm处横切,用弯虹膜钳钳夹残端轻柔地探入动脉内约0.5cm深处,随之用钳
32 newborns within 3 hours after birth were selected to undergo traditional and side-entry intubation respectively, 16 cases in each method to compare the advantages and disadvantages of the two methods. Ten nurses with experience of umbilical artery intubation of 3.5 years on average performed two types of intubation. Amplitude 1.5 to 10 years 7 of them routinely use the traditional method, 3 with the lateral method. Children in the warm box, while monitoring heart rate, respiration, blood pressure, oxygen saturation. Children with fixed limbs, skin preparation in the abdomen, tied knot on the umbilical cord to control bleeding. According to the size of neonatal choice 3.5 or 5.0 catheter, intubation then tectonic tube heparinization. The traditional method is at the proximal 1cm crosscut, with curved iris forceps clamp stump softly into the artery about 0.5cm depth, followed by the use of forceps
