High blood count after open sinus surgery can be routinely treated with anti-infection, if accompanied by high fever, use antipyretic and analgesic drugs to lower the body temperature, and at the same time, pay attention to the characteristics of local secretions and the corresponding disposition. High blood count refers to the white blood cell count exceeding normal in routine blood examination. The increase of white blood cell count after sinus opening surgery is the stress reaction of the body after surgery, and it can be returned to normal in 3~5 days after surgery. If accompanied by fever and increased localized purulent secretion or related naso-ocular and naso-cranial complications, it is considered to be postoperative infection. Treatment includes general treatment, anti-infection treatment and symptomatic treatment. 1. General treatment: pay attention to timely removal of nasal and sinus secretions; strengthen nutrition, diet should be light and nutritious and easy to digest, those who can not eat should be given intravenous supplementation of nutrients and fluids. 2. Anti-infection treatment: choose sensitive and sufficient amount of antibiotics, such as penicillin and cephalosporin drug combination, or choose sensitive antibacterial drugs by doing secretion culture to control infection. 3. Symptomatic treatment: if accompanied by high fever, use ibuprofen and other antipyretic analgesics to reduce body temperature. If this situation occurs after sinus opening surgery, consult the competent doctor and standardize the diagnosis and treatment with the clinical manifestations.
