ABSTRACT
Objective To analyze the epidemiological characteristics of an outbreak of carbapenem resistant Klebsiella pneumoniae(CRKP)hospital infection in the neonatal intensive care unit(NICU),and to explore possible causes of the outbreak.Methods Case analysis,epidemiological studies and environmental detection methods were used to investigate the detection of CRKP in the NICU of a hospital from March 11,2022 to May 3,2022,and the causes and corresponding prevention and control measures were analyzed.Results This CRKP outbreak in the NICU occurred in two phases.The first phase was from March 11,2022,to March 30,2022,during which 3 people contracted CRKP hospital infections.The second phase was from April 13,2022,to May 3,2022,during which 4 people contracted CRKP hospital infections.The source of the hospital infection outbreak was patient No.1.All 13 CRKP cases showed sensitivity only to amikacin and tigecycline,with intermediate sensitivity to levofloxacin,and high resistance to other antibiotics.All 13 CRKP cases carried resistant genes for metalloenzymes.After the outbreak,the ward environment was sampled three times,with 35 samples taken in total,and 14 of them tested positive for CRKP.After strict environmental cleaning,disinfection,and multiple control measures,no new hospital infection cases similar to this outbreak were detected after May 13,2022.Conclusion The outbreak of NICU hospital infections may be due to the contamination of the ward environment,medical equipment,and inadequate hand hygiene of medical staff,leading to its spread.Therefore,strict cleaning and disinfection of the environmental surfaces,strengthening hand hygiene of medical staff,and implementing multiple measures can effectively control hospital infections of CRKP.
ABSTRACT
Objective To summarize the characteristics of TCM syndrome of epidemic encephalitis B by retrospective analysis,provide the reference for the clinical diagnosis and treatment. Methods A form of collecting TCM syndrome was disigned and filled.Clinical date were collected from 85 cases of epidemic encephalitis B. We analysised and con-cluded the characteristic of TCM syndrome. Results The main TCM syndrome included fever and nausea ,coma and aversion to cold,shiver, vomiting,sag,convulsion,drowsiness.The classification of TCM syndromes were two types. One was the harm with QIFEN and YINGFEN,the other was the harm with WEIFEN and QIFEN. Conclusion The main classification of TCM syndromes of epidemic encephalitis B was the harm with QIFEN and YINGFEN,it was serious, but the other one was eusemia.It is important to treat in QIFEN phase ,which will control the patient ’s condition.
