外科手术切开

答案

参考答案:

1.较长的切口可预先用2%龙胆紫溶液及碘酊做好标记,以求准确。切开时要固定皮肤。小切口由术者用拇指、食指在切口两侧固定。较长切口由术者和助手在切口两侧或上下固定皮肤。

2.做长切口时,术者及助手各用左手掌尺侧缘,隔以掩盖皮肤的干血垫,压住切口线两侧皮肤,并稍用力向两侧轻轻牵引,使皮肤平整,易于切开并能使切缘整齐。

3.任何皮肤切口应以下刀后一次切完为佳,如此可减少组织损伤。下刀时刀片平面应与皮肤垂直。切开皮肤后,宜另换手术刀,以免将皮肤残存的细菌带到手术野深处。

4.切开皮下组织、止血后,用治疗巾覆盖切口创缘四周。以避免深部组织受污染。

5.切开时应防止损伤深部组织器官,如切开胸膜或腹膜时,要防止器官损伤,再次手术时,胸腔或腹腔有粘连,更应注意。

Once I thought love meant flowers, gifts and sweet kisses. So, I really doubted whether there was any love between my parents. Every day they were working hard to pay for my high school. They didn’t act in the romantic ways that I read in books and saw on TV, and they certainly didn’t send flowers to each other on Valentine’s Day (情人节).

One day, my mother was sewing a quilt (被子). I asked her if there was any love between her and my dad. She stopped and raised her head in surprise. Then she went on with her work without saying anything. I was very worried because I thought I had hurt her feelings. But after a few minutes she said, “Look at this thread (线). Sometimes it appears, but most of the time it disappears in the quilt. If life is a quilt, then love is the thread. It can hardly be seen anywhere or at any time, but it’s really there, and makes the quilt long-lasting.” I listened carefully but I didn’t understand her until the next spring.

My mother suddenly got seriously ill and had to stay in hospital for about a month. Every morning and evening after she returned from the hospital, my father helped her walk slowly along our country road. There were many beautiful flowers, green grass and trees, and the sun gently shone through the leaves. All of this made the most beautiful picture in the world. Reading their eyes, I knew they love each other deeply. From this experience, I realized that love is just a thread in the quilt of our lives. Love is inside, making life strong and warm.
