The hypodermic needle injection shallow the lump

Drug administration is a common way of drug administration. The drug is quickly absorbed and will not be destroyed by digestive enzymes. It is often used for drugs such as insulin that cannot be taken orally. If the puncture Angle is too shallow, the tilted surface of the tip during injection can accumulate in the local tissue, and the drug fluid can accumulate, resulting in a large local lump with painful symptoms.

When injecting shallow swelling, the affected limb can be lifted, and the affected limb can be placed in the chest when resting or sleeping. After swelling, local cold compress can also be carried out intermittently to avoid the needle spot and reduce the temperature of the skin surface, which can relieve pain and relieve edema. In addition, soak sterile gauze with 50% magnesium sulfate, cover the affected area, and then spray on the surface of gauze after drying, which can play a role in dilating blood vessels and promoting absorption. Fresh potato chips cold compress big bag, can reduce swelling, pain, late local hot compress, can promote local blood circulation, can also promote the absorption of liquid medicine, but pay attention to avoid burns when hot compress.

In addition, if the blood vessel is not carefully injected, it will also lead to local swelling. At this time, the color of the large swelling is purple, which can be used for local pressure hemostasis in the early stage, and the treatment in the later stage is the same as above. In summary, the injection of hypodermic needles shallowly bulges and requires aggressive management to avoid serious complications.
