Abstract:
OBJECTIVE To analyze the bacterial distribution and drug-sensitivity in sputum bacterial culture of the hospitalized patients with respiratory tract infection in the department of respiratory medicine to help reasonably choose the antibiotics and reduce the nosocomial infection rate. METHODS The bacterial infection of all the hospitalized patients with lower respiratory tract infection in the department of respiratory medicine from 2004 to 2005 was analyzed retrospectively and compared with all the patients of the hospital. RESULTS The nosocomial infection rate of the department of respiratory medicine in 2005 was 10.18%,which was higher than the rate of nosocomial infection of the whole hospital(3.09%).The Gram-negative bacteria were the main ones infected through respiratory tract.What should be paid attention to was the comparably higher fungal infection rate in 2005.The main Gram-negative bacteria were dominated by Pseudomonas aeruginosa.The most sensitive drug was piperacillin+ tazobactam in 2004 and aminoglycoside antibiotics in 2005.The Gram-positive bacteria were most sensitive to vancomycin. CONCLUSIONS The nosocomial infection is dominated by lower respiratory tract infection in the department of respiratory medicine.The nosocomial infection rate,dominated by Gram-negative bacteria is high.In order to decrease nosocomial infection rate,cross infection should be avoided,sensitive antibiotics be chosen,body resistance be enhanced and hospital stay be reduced.
