Objective To explore the effectiveness and safety of self-made washable endotracheal tube for subglottic secretion drainage. Methods Ordinary endotracheal tube and sputum aspirating tubes were used to make washable endotracheal tube for subglottic secretion drainage in our hospital. The self-made tubes were compared with washable endotracheal tube available on the market. The suction resistance, the cases of obstruction in the tubes, the average daily drainage, and the cases of infection of incisional wound were compared between the two kinds of tubes, and their safety was evaluated. Results After three days of application, the suction resistance of endotracheal tube available on the market increased, with six cases of the blockage of the lumen ( 85% ) , while that of self-made endotracheal tube did not change, with no cases of blockage ( 0% ) . There was significant difference between these two kinds of tubes ( P lt;0. 01) . The average daily drainage in the former was ( 16. 55 ±8. 66) mL/d; while that in the latter was ( 40. 12 ±25. 48) mL/d. There was no significant statistical difference between the two kinds of tubes ( P gt;0. 05) . The incidence ofinfection of incisional wound in the ordinary endotracheal tube was 50% ( 5 cases) ; that in the tubes available on the market was 28% ( 2 cases) ; that in the self-made tubes was 15% ( 2 cases) . There was significant difference among the three groups. When tube cuffs were inflated, the distance between the back edge of suction tubes and tube cuffs was was 2-4 mm. Conclusion Self-made washable endotracheal tubes are effective for subglottic secretion drainage with good safety and low price.
ObjectiveTo investigate the role of dynamic monitoring procalcitonin (PCT) in the comprehensive evaluation during the diagnosis and treatment of community acquired pneumonia (CAP).
MethodsFour hundred and sixty-eight patients with CAP were randomly assigned to a PCT-guided group (the research group) and a standard guideline group (the control group). The clinical symptoms,CURB-65 grade,blood leucocyte count and classification,and C-reactive protein (CRP)were compared between two groups. The PCT-guided application time of antibiotics,the hospitalization time,chest CT examination rate,the cure or the improvement rate were also estimated and commpared.
ResultsThe hospitalization time [(9.6±1.7)days vs. (10.9±1.6)days],hospitalization cost [(6 957.11±1 009.46) yuan vs. (8 011.35±1 049.77) yuan],chest CT examination rate (56.96% vs. 89.40%),the application time of antibiotics [(16.5±2.3)days vs. (20.0±1.2)days],and the rate of required antibiotics upgrade (6.96% vs. 11.06%) in the research group were all significantly lower than the control group (P<0.05). There was no significant difference between two groups in the ratio of the adverse reaction of antibiotics (14.78% vs. 15.20%),the rate of transfer into ICU (2.61% vs. 3.69%) or the mortality (1.74% vs. 2.30%)(P>0.05).
ConclusionOn the basis of CAP guidelines,the dynamic monitoring of PCT may shorten the time of antibiotic use and the hospitalization,reduce the cost of hospitalization and the rate of chest CT scan in patients with CAP.
Objective
To analyze the clinical outcome of one-stage repair of aortic coarctation combined with cardiac anomalies and pneumonia.
Methods
We retrospectively reviewed the clinical data of 26 patients with severe pneumonia undergoing repair of aortic coartation between January 2014 and August 2015, among whom 7 patients (26.9%) received tracheal intubation, 5 patients double incision, and 21 patients single incision. Long-term follow-up results were obtained from outpatient department.
Results
Two patients died from operations. The mean hospital stay was 18.5±4.5 d, bypass time 93.5±36.4 min, and mechanical ventilation time 89.5±41.3 min. Postoperative complication mainly was pneumonia. During 6-month follow-up at outpatient department, incidence of pneumonia decreased, and children’s growth and development remarkably improved.
Conclusion
In the case of uncontrollable pneumonia, one-stage repair of aortic coarctation associated with cardiac anomalies still can receive a good outcome.
To prevent and control 2019 novel coronavirus pneumonia diseases (COVID-19), hundreds of medical teams and tens of thousands of medical professionals throughout the nation were transferred to Hubei to assist COVID-19 control efforts. Medical professionals were at high risk of novel coronavirus pneumonia infections. To ensure the prevention and control of infection in medical teams and prevent cross-infection among medical staff at the medical station, this management standard includes routine management standards, resident disinfection, personnel entry and exit process, and logistics support management, so as to provide reference for medical teams combating COVID-19 in the future.
ObjectiveTo explore the clinical, radiological and pathological characteristics of acute fibrinous and organizing pneumonia (AFOP).
MethodsA case pathologically diagnosed with AFOP in September 2013 in the Second Affiliated Hospital of Nanjing Medical University was reported, and the related literature was reviewed.
ResultsA 50-year-old woman with fever, chills, cough with sputum and chest pain was admitted to this hospital. The chest CT showed the nodules and patching infiltrates of the right middle lung. The pathological examination revealed the focally exudation of fibrin, lymphocyte infiltration and the presence of foam cells within the alveolar spaces, which is different from other well-known acute lung injures such as diffuse alveolar damage, cryptogenic organizing pneumonitis, and acute eosinophilic pneumonia. Coticosteroid therapy was induced and the patient showed significantly clinical and radiological improvement.
ConclusionAFOP has no specific clinical, laboratory tests and radiology features, and it's diagnosis depends on pathological examination. Treatment with coticosteroids is proved to be effective.
ObjectiveTo investigate the strategy adjustment of breast cancer surgery management process during the outbreak of novel coronavirus pneumonia (NCP), and to summarize the experience.MethodsBased on "Pneumonitis Diagnosis and Treatment Plan for Novel Coronavirus Infection (Fifth Trial Version)" and "Surgery Work System During the Prevention and Control of Novel Coronavirus Infection in Mianyang Central Hospital (Second Edition)", the breast surgery department adjusted strategies and plans for breast cancer surgery during the epidemic.ResultsFrom January 25, 2020 to February 11, 2020, 8 cases of breast cancer surgery were performed in our hospital. They were all females, with an average age of 45 years. Five patients underwent modified radical mastectomy, 2 patients underwent breast-conserving surgery plus sentinel lymph nodes biopsy, and 1 case underwent breast-conserving surgery plus axillary lymph node dissection. All 8 patients were diagnosed as invasive ductal carcinoma of breast by hollow needle biopsy. All patients recovered smoothly after surgery, no complications occurred, and they were discharged as planned. No patients or medical staff showed NCP exposure and infection.ConclusionDuring the NCP epidemic, breast cancer surgery can be performed and the epidemic can be effectively prevented and controlled by adjusting the work flow and strategy.
Objective
To investigate the clinical characteristics and bacterial drug resistance of bloodstream infection of gram-negative bacteria, and provide guidance for clinical rational drug use and control of hospital infection.
Methods
A retrospective analysis was conducted in the patients diagnosed as severe pneumonia with blood culture of gram-negative bacteria from January 2015 to December 2017 in Beijing Anzhen Hospital.
Results
A total of 60 severe pneumonia patients suffered from bloodstream infection of gram-negative bacteria were recruited including 34 males and 26 females aging from 42 to 89 years and 73.4 years in average. In the 60 patients, 32 cases were infected with Klebsiella pneumonias, 20 cases were infected with Acinetobacter baumanni, and 8 cases were infected with Escherichia coli. The antimicrobial susceptibility testing result of Klebsiella pneumonias showed that the drug susceptibility rate was 100% to tigecycline, and 6.3% to amikacin. Escherichia coli was sensitive to Amikacin, imipenem, ceftazidime and meropenem while resistance to other drugs. The antimicrobial resistance of Acinetobacter baumanni was 28.6% for cefoperazone/sulbactam, and 14.3% for tigecycline. C-reactive protein, procalcitonin and SOFA scores were higher in the patients infected with Acinetobacter baumanni. Neutrophils and blood lactic acid were higher in the patients infected with Klebsiella pneumonias. There were no statistical differences in white blood cell, platelet or motality rate between the patients infected with Acinetobacter baumanni and the patients infected with Klebsiella pneumonias. SOFA scores and blood lactic acid had significantly statistical relevance with prognosis.
Conclusion
There is a high proportion of drug resistance of Klebsiella pneumoniae and Acinetobacter baumanni in the bloodstream infection of gram-negative bacteria.
Objective To explore the efficacy of continuous lateral rotation therapy ( CLRT) for the prevention of ventilator associated pneumonia ( VAP) . Methods Database of Medline and SinoMed were searched. Randomized and controlled trials assessing the efficacy of CLRT vs. placebo or conventional treatment for the prevention of VAP were included. Data were extracted on study population, exclusion and inclusion criteria, diagnostic criteria of VAP, incidence of VAP, ICU mortality, ICU length of stay, andduration of mechanical ventilation. The VAP incidence and mortality were extracted as dichotomous variables and the other parameters were extracted as continuous variables. The pooled analyses of VAP incidence and mortality were performed by using Review Manager 5. 0 software. The heterogeneity was analyzed by thestatistic I2 . Results A total of 5 clinical trials met the inclusion criteria. CLRT could reduce the incidence of VAP ( OR=0. 50,95% CI 0. 32-0. 78) , and the heterogeneity was not statistically significant. The impact of CLRT on the ICU mortality was insignificant. The ICU length of stay and duration of mechanical ventilationwere not significantly different between CLRT and control groups. Conclusion CLRT is beneficial for the prevention of VAP, whereas its impacts on other clinical outcomes such as the ICU mortality, ICU length of stay, and duration of mechanical ventilation require further investigations.
