Abstract:
Objective To investigate the clinical characteristics and therapeutic methods of bac-terial colonization and infection of Acinetobacter baumannii on the wound of earthquake induced patients. Methods A retrospective study was done on 42 Wenehuan earthquake induced patients with positive wound germiculture of Acinetobacter baumannii. There were 24 males and 18 females, at mean age of 37 years (12-96 years). Open injury was located at the upper arm in one patient, at the forearm in four, at the thigh in 12, at the calf in 23 and at the trunk in two. The time between injury and treatment varied from 3 to 7 days. The clinical characteristics including the bacteria identification and drug sensitivity test were studied to compare drug resistance to 15 antibiotics. Results Bacterial colonization of Acineto-bacter baumannii was found in 31 patients (8.2%) and infection of Acinetobacter baumannii in 11 (2.9%). After debridement, pruphylactic antibiotics and nutrition support, 15 patients with bacterial colonization were managed with Ⅱ stage suture or skin grafting. The other 16 patients were transferred to hospitals of other provinces after germiculture turned negative. Through debridement and drainage, antibi-otic therapy and nutrition support, the infection was controlled and the wound eliminated in six patients through Ⅱ stage suture but four were concomitant with pulmonary infection and one with septicemia. Drug sensitivity test showed that sensitive rate to imipenem, amikacin, levofloxacin, ticarcillin-clavulanic acid, tobramycin were 59.5%, 21.4%, 21.4%, 19.5% and 19.0% respectively. Conclusions The risk factors of infection of Acinetobacter baumannii include severe tissue trauma, severe wound contamination, delayed treatment and weak body resistance. During treatment, the bacterial colonization and infection of Acinetobacter baumannii should be distinguished and treated respectively. Correct wound treatment, suit-able antibiotic therapy and increased body resistance are key to improvement of clinical curative effect.
