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 systematically review the efficacy and safety of vaccines for the coronavirus disease 2019 (COVID-19) . Methods The CNKI, VIP, WanFang Data, PubMed, EMbase and Web of Science databases were electronically searched to collect randomized controlled trials (RCTs) on the safety and efficacy of COVID-19 vaccines from their inception to June 30th, 2022. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software and Stata 12.0 software. Results A total of 13 RCTs involving 139 015 subjects were included. The results of meta-analysis showed that the sero-antibody conversion rate (RR=37.883, 95%CI 8.086 to 177.491, P<0.001) and infection prevention rate (RR=1.011, 95%CI 1.006 to 1.017, P<0.001) of the vaccine group were higher than those of the placebo group. The incidence of adverse reactions in the vaccine group was higher than that in the placebo group (OR=1.839, 95%CI 1.165 to 2.903, P=0.009), which mainly included pain, redness, swelling, fever, headache and itching (P<0.05). However, the incidence of serious adverse reactions was not significantly different from that of the placebo group. Conclusion The current evidence shows that the efficacy of the COVID-19 vaccines is high. The most prevalent adverse reactions are mild and moderate, and severe adverse reactions are the same as those of the placebo group. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
