Local anesthesia operation
Strict aseptic operation. Although anal disease is a bacterium operation, medical personnel musttreat it asaseptic operation. Perianal skin disinfection should berange, large. Iodine, bromo-geramine, Chlorhexidine and other disinfection drugs are available. The injection site: 12 clock direction can be the first position while patient ingenucubital position .Put the needle into skin, then along this point to 3, 9clockdirection, and then by 3, 9 points to 6 points, respectively, subcutaneous infiltration anesthesia.
After anesthesia expand anus, anal relaxation beoreoperation.
The patients were placed in lateral position, back bent, knees close to the abdominal wall.
About 4-5cm up to the coccygeal tip there are two sacral cornus, then up to the middle partit isfourth sacral spine .It is a bone uplift.
In middle between two sacral cornus and fourth sacral spine there is an soft tissue depression, it issacral hiatus. And in the depths of the bony edges can touch the skin, with a fingernail do identification, routine disinfection.
With a 20ml syringe inhalation liquid, 6-6.5 needle head, through the sacral hiatus hole,put the needle into the skin with 90 degree angle with skin, releasing small amount of anesthesia while deeper and deeper.
When the needle pierced the sacral ligament tissue and fibrous tissue after tail resistance significantly plummeted a sense of frustration, that has arrived in the sacral lumen. Pumpback syringe without blood and cerebrospinal fluid inject anesthetic 20-30 ml.
