Experimental study and reflection on peacetime and wartime reconstruction of large general hospitals in public health emergencies / 中南大学学报(医学版)

To propose the architectural layout for the big general hospital in the face of public health emergencies, we analyzed the conditions, methods, problems and countermeasures for the reconstruction of the isolation ward from the existing medical building layout of a general hospital. The affected areas met the requirements of isolation ward in the reconstruction, and realized the corresponding partition and separation of people. But the cost of occupying the medical room should be concerned. General hospital should be alerted to potential risks of public health emergencies. The characteristics of different construction types, defects, and the function of the hospital should be considered in the construction, rebuilding, and expansion of the hospital, which shouldnot only meet the needs of the development of the hospital daily usage but also consider dealing with emergent public health events. We can adopt the reasonable layout, including setting up a firewall-like device between the channel and the floor, an ordinary ward at ordinary times, and an independent space for emergency by pulling down the gate. This strategy can not only avoid the problem of low utilization rate of the space occupied by the corresponding area in the ward for diseases spread by air and droplets, maximizing the efficiency of the medical site, but also avoid the problem of emergency response to the temporary reconstruction.

Clinical analysis for patients with continuous ambulatory peritoneal dialysis associated peritonitis / 中南大学学报(医学版)

To analyze the clinical characteristics of continuous ambulatory peritoneal dialysis (CAPD) associated peritonitis in the tertiary hospitals and to discuss the preventive and therapeutic strategy.
 Methods: The clinical characteristics, pathogens, resistance and outcomes of 126 CAPD associated peritonitis in 104 patients from Jan, 2013 to June, 2016, were retrospectively analyzed.
 Results: Among the patients, the incidence rates of abdominal pain, fever, diarrhea and emesis were 104 (82.54%), 56 (44.44%), 49 (38.89%), and 31 (23.60%), respectively. Among them, 88 patients suffered peritonitis once, other 16 patients suffered multiple peritonitis or recurrent peritonitis for 38 times. Among the 38 times, the numbers for recurrent, repeated or catheter-associated peritonitis were 2, 2, or 3, respectively. Peritoneal fluids from 103 cases were cultured, and 64 cases were positive in bacteria, with a rate of 62.14%. A total of 70 strains of bacteria were separated, including 42 strains of gram-positive bacteria, 21 strains of gram-negative bacteria, and 7 strains of fungus. The most common gram-positive pathogens were Staphylococcus epidermidis, Enterococcus faecalis and Staphylococcus haemolyticus, while Escherichia coli, Klebsiella pneumoniae and Klebsiella pneumoniae were the most common gram-negative bacteria. Candida albicans was the major fungal pathogens. Gram-positive cocci showed resistance to gentamycin, levofloxacin, moxifloxacin, vancomycin and linezolid, with a rate at 20.00%, 36.11%, 5%, 0%, and 0%, respectively. The gram-negative bacilli were resistent to cefoperazone/sulbactam, gentamycin, cephazolin, and ceftazidime, with a rate at 6.25%, 10.53%, 64.29%, and 15.38%, respectively. There were no imipenem, amikacin, piperacillin/tazobactam-resistant strains were found.
 Conclusion: The most common pathogen causing CAPD associated peritonitis is gram-positive bacteria. It is crucial to take the anti-infection therapy for CAPD associated peritonitis early. The positive rates for bacterial culture need to be enhanced through improvement of methods. At the same time, doctors could improve the outcome of CAPD associated peritonitis by adjusting the medication according to the drug sensitivity results.
