RESUMEN
Objective:To explore the effect of self-made protective clothing in tracheal intubation for the patients with respiratory infectious diseases.Methods:Self-made protective clothing were made by adult model plastic raincoat with sleeve lets and goggles. A prospective randomized controlled study was conducted. Patients with severe respiratory infectious diseases who needed tracheal intubation admitted to the department of intensive medicine of the Third Affiliated Hospital of Gansu University of Chinese Medicine from January 1st 2018 to March 31st 2020 were enrolled. According to the random number table method, they were divided into two groups. The control group was wearing standard protective clothing, while the test group was wearing self-made protective clothing for endotracheal intubation. The wearing time, infection rate of operators and costs of protective clothing were compared between the two groups. The patients were sprayed with trypanosome blue diluent before tracheal intubation, and the whole body of the operator was photographed with fluorescence before wearing self-made protective clothing and after doing tracheal intubation to take off the self-made protective clothing, in order to evaluate the permeability resistance of self-made protective clothing.Results:A total of 86 patients were enrolled. There were 46 cases in the test group, included 28 cases of influenza A (H1N1) virus infection, 11 cases of influenza B virus infection and 7 cases of adenovirus infection. There were 40 cases in the control group, included 15 cases of H1N1 virus infection, 10 cases of influenza B virus infection, 10 cases of adenovirus infection and 5 cases of unknown pathogen. There was no significant difference in respiratory etiology between the two groups ( χ2 = 3.789, P = 0.435). The wearing protective clothing time of the control group was 11.6 times than that of the test group (minutes: 22.23±1.45 vs. 1.86±0.24, χ2 = 19.023, P < 0.001). The cost of standard protective clothing was 12.5 times than that of self-made protective clothing (Yuan/set: 500 vs. 40). Fluorescent photography showed that the whole body of the operator was not stained after tracheal intubation, indicating that the protective clothing had good anti permeability and achieved the protective effect. There was no operator infection in the test group and the control group. Conclusion:Self-made protective clothing has short wearing time, low cost and equivalent isolation effect compared with standard protective clothing, which is worthy of clinical promotion.
RESUMEN
Objective To compare the survival rates from two conservative strategies in the treatment of malignant pleural mesothelioma (pemetrexed plus cisplatin or pemetrexed plus carboplatin ).Methods Seventeen cases diagnosed of malignant pleural mesothelioma at clinical stages of or over Butchart Ⅲ in our hospital during 2005 -2009 were treated with pemetrexed plus cisplatin (10 cases,Group A)or pemetrexed plus carboplatin (7 cases,Group B ).The difference in the survival rates between these two groups was compared.Results The early survival rate (0 -3 months)in pemetrexed plus cisplatin (group A)-treated group was more than that of pemetrexed plus carboplatin group (group B),but the difference was not statistically significant (x2 =0,1.52,1.52,respectively,P ＞ 0.05 ).For the medium-term survival rate (4 - 9 months),group A was better than group B,and the difference was statistically significant( x2 =5.21,4.41,4.41,4.50,4.50,4.55,respectively,P ＜ 0.05 ).The two groups produced comparable long-term survival rate s (10 -12months) ( x2 =1.31,0.09,0.09,respectively,P ＞ 0.05 ).Conclusion To increase the medium-term survival rate (4 -9 months)of patients with MPM,we prefer to using pemetrexed plus cisplatin regime.For the patients with more severe side effects which can be relieved by folic acid and VitB12,this regime is also recommended.Otherwise,for the patients with unrelievable side effects,especially for those with poor physical condition or a short survival expectation,pemetrexed plus carboplatin is suggested.
