ObjectiveTo investigate the situation of hospital infection with bacteria producing extended-spectrum β-lactamases (ESBLs), find the source of infection and analyze its transmission route, and take effective prevention and control measures to reduce the incidence of nosocomial infection. MethodsA hospital neonatal ward had six cases of ESBL-producing bacteria infections on February 16 to 26, 2012. According to the processing procedure for hospital infection outbreak, we carried out epidemiological investigation on the patient with suspected hospital infection, including checking the medical records, asking the doctor in charge about the patients'clinical symptoms, collecting sputum samples of the patients and environmental microbiology examination, etc. ResultsFour cases of infection were community-acquired, and two were nosocomial infection. Infection onsets were concentrated (between February 16 and February 26, 2012). Patients had similar clinical symptoms, including fever, cough, cough sputum, and lung wet rales, which showed a lower respiratory infection. Six strains of ESBL-producing Escherichia coli were isolated from the infected children, and their susceptibility reports were not entirely consistent, indicating that they did not belong to the same species and were not homologous pathogens. Through bedside survey, we also isolated from the environmental samples 6 ESBL-producing bacteria, and these bacteria were acquired from the milk countertops, kettle, ventilator tube, two doctors'nasal cavity, and the cleaners'nasal cavity in corresponding wards of those infected children. ConclusionThe infection does not belong to an outbreak of nosocomial infection, and it is only an aggregation event of ESBL-producing Escherichia coli. The symptoms of infection were mainly because of lower immunity of children themselves, plus not so good aseptic technique and management in the department of neonatology. Therefore, strengthening hand hygiene management of medical staffs, and regular environmental sanitation and disinfection can reduce the incidence of neonatal hospital infection.
ObjectiveTo investigate the prevalence of nosocomial infection in a hospital and to provide a basis for hospital infection control. MethodsUsing bedside investigation and medical records analysis, we surveyed all hospitalized patients from 00:00 to 24:00 on July 19th, 2013. ResultsThe real investigation was carried out on 1815 patients out of all the 1828 patients with a real investigation rate of 99.29%. There were 55 cases of nosocomial infection (55 case-times), and both the nosocomial point infection rate and case-time infection rate were 3.03%. The top three departments with the highest rate were Intensive Care Unit (37.50%), Neurosurgery Department One (13.73%) and Neurosurgery Department Two (12.00%). Most infections occurred on the lower respiratory tract, which accounted for 45.45%. Nosocomial infection pathogenic detection rate was 38.18% (21/55):6 cases of Staphylococcus aureus (28.57%), 5 of Pseudomonas aeruginosa (23.81%), 3 of Klebsiella pneumoniae (14.29%), and 2 cases of Acinetobacter baumanii (9.52%). The rate of antimicrobial drug use was 24.08%, in which drug treatment accounted for 75.29%. Gender, surgery, urinary catheter, vascular catheter, tracheostomy, ventilator application, hemodialysis, and use of antibiotics were all influencial factors for occurrence of nosocomial infection. ConclusionNosocomial infection prevalence survey can help fully understand the status of hospital infection, help to carry out targeted surveillance, and better guidance for hospital to prevent and control nosocomial infection.
ObjectiveTo compare the effect of laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE) in the treatment of cholecystolithiasis combined with choledocholithiasis in elderly patients and non-elderly patients. MethodsThe clinical data of 185 cases of cholecystolithiasis combined with choledocholithiasis who treated in our hospital from September 2010 to November 2015 were analyzed retrospectively. Then the 185 cases of holecystolithiasis combined with choledocholithiasis were divided into elderly patients group (n=74) and the non-elderly patients group (n=111). The operative time, intraoperative blood loss, postoperative exhaust time, postoperative activity time, abdominal drainage time, postoperative hospital stay, total hospital stay, hospitalization cost, incidence of complications, unplanned analgesia, stone-free rate, rate of conversion to laparotomy, recurrence of stone, and mortality were compared between the two groups. Results① Intraoperative and postoperative indexes. No significant difference was noted in operative time and intraoperative blood loss (P > 0.050), but the postoperative exhaust time, postoperative activity time, abdominal drainage time, postoperative hospital stay, total hospital stay, hospitalization cost, and ratio of indwelling T tube of elderly patients group were all higher or longer than corresponding index of non-elderly patients group (P < 0.050). ② Postoperative complications and unplanned analgesia. There was no striking discrepancy in incidence of complications (including biliary leakage, peritonitis, haemorrhage, vomit, ectoralgia, and fever), and Clavien-Dindo grade (P > 0.050), except unplanned analgesia (P=0.007), the rate of unplanned analgesia in elderly patients group was higher than that of non-elderly patients group. ③Surgical effect. There was no significant difference in the stone-free rate, rate of conversion to laparotomy, and rate of recurrence of stone between the 2 groups (P > 0.050). ConclusionLC+LCBDE is also safe and effective in treatment of cholecystolithiasis combined with choledocholithiasis in elderly patients, it's worthy to be expanded and be used broadly.
ObjectiveTo observe the effects of oral Xiaoyan Lidan tablets(XYLDT) on the bile composition(total bile acids, cholesterol, phospholipids) in patients with intrahepatic duct stones after common bile duct exploration(CBDE) with T tube drainage, to explore its possible preventive effects on stone recurrence. MethodsForty consecutive patients with intrahepatic bile duct stones who underwent CBDE with T tube drainage were randomly divided into experi mental group and control group. XYLDT were administrated at day 4 after surgery in experimental group(n=20), while none of medication were given in control group(n=20). 2 mL of bile was collected through T tube in both groups at day 1, 2, 3, 7, 14, and 21 postoperatively. Total bile acids(TBA), cholesterol(CHO), and phospholipids(PLIP) in bile were measured, and TBA/CHO ratio and PLIP/CHO ratio were calculated respectively. The results were statistical analyzed. ResultsThe demographic data in both groups including age, gender, height, weight, preoperative concomitant diseases, operative time, postoperative complications, hospital stays, serum total bilirubin, direct bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), and amylase were not significantly different(P > 0.05). The measurements of TBA, CHO, PLIP, and the ratio of TBA/CHO and PLIP/CHO in bile were not significant on day 1, 2, and 3 after surgery in both groups(P > 0.05). In experimental group, the TBA, CHO, and PLIP on day 7, 14, and 21 after surgery were significantly increased compared with the control group(P < 0.05). The ratio of TBA/CHO on day 7, 14, and 21 was 2.17±0.29, 2.29±0.44, and 2.59±0.58, the ratio of PLIP/CHO was 2.03±0.68, 2.84±0.64, and 2.86±0.77, respectively, which were also significantly increased compared with the control group(P < 0.05). ConclusionsOral XYLDT can increase the secretion of TBA, CHO, and PLIP, elevate the TBA/CHO and PLIP/CHO ratio, and change the bile composition which may increase the dissolution of cholesterol in the bile. Presumably, oral XYLDT may have preventive effects in the recurrence of intrahepatic bile duct stones.
ObjectiveTo investigate the feasibility, safety, cost, and patient satisfaction of ambulatory laparo-scopic cholecystectomy(ALC). MethodsThe clinical data of patients who divided into ALC group(678 cases) and in-patient laparoscopic cholecystectomy(IPLC) group(1 534 cases) in our hospital from April 2011 to December 2012 were retrospectively analyzed. The operative time, conversion rate, complication rate, hospitalization time, cost of hospi-talization, rehospitalization rate, and patient satisfaction were analyzed and evaluated. ResultsThere were no significant differences of the operative time, postoperative complication rate, and rehospitalization rate between the 2 groups(P > 0.05). The conversion rate(0.44%), and hospitalization time[(1.2±0.5)d] of the ALC group were significantly lower or shorter than those of IPLC group[3.19%, (4.8±1.3) d], P < 0.05. The direct, indirect health care costs, and the total costs of the ALC group were (6 555.6±738.7), (230.0±48.0), and (8 856.0±636.0) yuan, respec-tively; and lower than those of the IPLC group[(7 863.71, 014.6), (973.0±136.5), and(8 856.0±636.0)yuan], P < 0.05. ConclusionALC is safe and feasible, and could shorten the hospitalization time, lower the medical cost, speed up the bed turnover, and increase the efficiency in the use of health resource.
