Hernia surgery is usually compressed with a salt bag for 6 hours, can also be compressed with a saline ice pack for 6h, specific need to comply with medical advice. Inguinal hernia is a common surgical disease, so far surgery is still the most effective and direct method. Pain, bleeding and edema are the most common early postoperative complications of inguinal hernia, so local compression of the incision is very important. Commonly used methods are sandbag, salt bag compression and saline ice bag compression method. 1. Sandbag, salt bag compression: patients take the lying position after surgery, routinely placed sandbag or salt bag (1000g) compression incision site 6h, keep the room temperature 18 ~ 22 ℃. The disadvantage is that, only the use of gravity to reduce the local blood seepage, but can not achieve the purpose of complete hemostasis and pain relief. 2. Saline ice bag compression method: with a dry towel bag wrapped in 10% saline ice bag 2 placed on the incision dressing (8 layers of 8cm × 10cm sterile gauze) and set on the hernia bag, 3h replacement of the saline ice bag 1 time, continuous cold compress 6h, keep the room temperature 18 ~ 22 ℃. Cold compress can make the microvascular contraction, permeability reduction, reduce bleeding, slow down the rate of nerve conduction, with hemostasis, pain, swelling effect. Incisional compression as a common nursing measure after inguinal hernia surgery, the patient if in the process of serious wound bleeding, pain and other symptoms, must promptly report the situation to the doctor in charge of the doctor’s orders.
