To research the clinical efficacy of continuous lavage technology in the treatment of severe oral and maxillofacial multi-space infection.

From January 2017 to October 2018, 18 cases of severe maxillofacial multi-space infection treated by Department of Burns and Plastic Surgery, Fourth Medical Center of People′s Liberation Army General Hospital were collected. All abscess cavity of oral and maxillofacial were sufficiently incised and drained and placed irrigating device, according to the needs of the disease flushed with sufficient amount of saline every day, at the same time, auxiliary treatments such as using anti-infection, nutrition support and suppling rehydration were provided.Combined the requirements of clinical observation and research, evaluating comprehensively the overall and local conditions of patients, including blood test, imaging examination, bacterial culture, etc. The key observation indicators included the total number of white blood cells, percentage of neutrophils, hemoglobin, blood sugar, albumin and so on. Recorded the degree of pain and swelling in maxillofacial region during treatment.

The swelling and pain of the maxillofacial region of 18 patients disappeared completely, the average number of white blood cells before treatment was 8.72×10⁹/L, the average number of white blood cells on the 3rd day after operation was 5.52× 10⁹/L, the average number of albumin before operation was 33.65 g/L, and the average number of albumin after operation was 38.25 g/L. The bacteria with higher detection rate were Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa. CT scan showed that the infection space was reduced and the swelling was alleviated after treatment.

Through continuous lavage technology, the necrotic tissues and secretionsis could be diluted and discharged from body continuously, reducing toxin and bacteria in to blood, which can control the disease in a short time.The continuous lavage technology is a new treatment for severe maxillofacial multi-space infection, which can shorten hospitalization time, save hospitalization expenses and lighten the burden of medical staff.
