男子拇指被狗咬断吞进胃里 1小时后被取出接上

2016-04-07 08:08:31   现代金报

下午4点半左右,沈先生进了手术室,主刀的是手外科副主任医师潘佳栋。眼前的这截断指,经过胃酸的侵蚀已经发白,部分血管等组织已经被消化。这个断指再植手术,对于有12年从医经历的潘佳栋来说,技术难度不大,但风险不小,“因为断指被胃酸浸泡过,会有各种细菌,感染的风险特别大”。

手术第一步是在显微镜下清创伤口。一般的清创半小时就够了,而这次足足用了一个多小时。“的胃里还有其他食物,会有很多细菌,清创必须非常仔细,被消化过的各种组织也要清创干净,尽量把感染的风险降到最低。”

清创结束后,开始接断指。因为部分血管被消化,潘佳栋从沈先生的左前臂取了一段3.5厘米长的血管,移植到断指上,用作拇指的动脉。这次手术,总共缝了三根血管。

根据之前的会诊,沈先生的手术分两期进行。第一期是接好断骨,修复血管和神经,保证手指存活;第二期是一两个月后,缝合肌腱,重修拇指功能。所以,潘佳栋在这次手术中,把下次手术要缝合的肌腱做好标识,最后缝合血管表皮。整个手术持续近4个小时。

经观察沈先生手指再植初步成功

这种手术国内外都很少见

断指再植成功的观察期一般是7天。目前,沈先生手指再植初步成功。等二期手术之后,经过功能康复,沈先生的拇指可以恢复大部分功能,像吃饭、系鞋带等都没问题。王欣说,六院手外科每年要做近千例手指再植手术,其中被狗、猫、甚至是人咬下来的断指经常碰到,但是被狗吞食后从胃里取出来的还是第一次碰到。

王欣查了资料,国内外碰到这种情况,一般不做再植手术,直接做残端清创处理。这是因为这种情况下的断指再植手术难度太大。

“首先,被动物咬下来的断指,通常是撕破伤,伤口不整齐;胃液有消化功能,断指被溶解侵蚀;另外狗的胃里有特殊的细菌,跟平时日常中碰到的细菌不一样,感染风险特别大,而再植手术很重要的一关就是感染关。”王欣说。

万一发生断指怎么办?王欣建议首先要用干净的水把断指清洗干净,然后找干净的毛巾或纱布包起来,放进塑料袋,外面再覆盖一层冰块,总之是要争取在最短的时间内送到医院。断指后,一般在6个小时之内,再植成功的可能性还是蛮大的。

服务提醒

春季动物进入发情期小心猫狗“为情”伤人

据了解,这条狗是黄色杂交牧羊犬。家属说,这条狗已经养了好些年,平时挺乖巧,沈先生待它就像家里的一员。这次,狗为什么突然发癫,大家也不知缘由。

在此,金报提醒大家:春天来临,市民外出春游要谨防身边的犬类。

春季万物复苏,狗、猫等动物进入发情期,“脾气”会变得暴躁一些。尤其是母狗,在发情期集中表现出焦急和暴躁的情绪,饲养和逗玩时都要格外注意,谨防其“为情”伤人,在狗有恐惧感的时候,不要用手或身体其他部位去抚慰它。

由于犬类具有很强的领地意识,容易攻击陌生人,所以不要接近或逗弄正在进食的狗、哺乳期的狗;切忌徒手分开正在相互嬉闹、撕咬的狗。另外,遭遇车祸的狗因为受到惊吓,也会咬伤救助者(包括狗主人),所以在救狗的时候也要注意保护自己。
