How does intramuscular injection sclerotic infection return a responsibility?
summary
How does intramuscular injection sclerotic infection return a responsibility? Intramuscular scleroma refers to the inflammatory proliferative reaction caused by the injection in the buttock or humeral triangle, which may be related to the reactive atrophy caused by the stimulation of the muscle by the needle and the concurrent bacterial infection.
How does intramuscular injection sclerotic infection return a responsibility?
The causes of intramuscular induration are frequent injection and repeated stimulation; After the injection of the drug into the muscle, due to the strong acidity or the chemical stimulation of the drug itself, the muscle fibrous tissue proliferated; * the local retention of the liquid can not be absorbed quickly. It can also cause infection due to lax disinfection of needles or operation (now the widespread promotion of disposable medical devices, the infection rate has decreased significantly), and then form mass induration, secondary local or systemic lesions.
Common symptoms: local swelling and pain, affect the activities of upper and lower limbs, fever, aversion to cold, the clinical manifestations of intramuscular injection induration infection are: local swelling and pain, affect the activities of upper and lower limbs, fever, aversion to cold, severe cases can appear deep suppuration or local necrosis. For patients with low constitution and long-term use of immunosuppressants, due to low resistance, pathogens spread into the blood circulation system through local tissues, resulting in sepsis, which can lead to septic shock.
Examination items: histological and pathological examination generally only needs general dermatological examination, which can be diagnosed by local swelling, pain, affecting the activities of upper and lower limbs, fever, chills, severe cases can appear deep suppuration or local necrosis and other clinical manifestations, plus injection history. In routine blood test, neutrophil count and total white blood cell count were often increased, ESR was usually increased, and C-reactive protein was positive or significantly increased.
matters needing attention
(1) Choose regular medical institutions to ensure the sterility of the device（ 2) The oil must be injected intramuscularly（ 3) If there is no hard result after injection, hot compress can be used appropriately（ 4) Avoid some strong irritant drugs intramuscular injection, especially some Chinese herbal medicine preparations, because the alcohol content extracted from Chinese herbal medicine can not reach a certain standard, which is easy to cause local muscle irritation（ 5) Minimize the chance of intramuscular injection（ 6) For patients who must be treated with long-term intramuscular injection, the injection site must be changed alternately（ 7) It is not suitable to inject in the parts with scar, induration, inflammatory skin disease, old needle eye, blood stasis and hematoma.
