RESUMO
Objective:To investigate the effect of deescalation noninvasive positive pressure ventilation in the removal of endotracheal intubation in patients with Stanford type A aortic dissection (AAD) complicated with obesity.Methods:A total of 80 obese patients with AAD from March 2018 to January 2020 in the First Affiliated Hospital of Xi′an Jiaotong University were divided into experimental group and control group with 40 cases in each group by random number table method. The control group received traditional oxygen treatment with mask, while the experimental group received de-escalation noninvasive positive pressure ventilation. The blood gas index, respiratory rate and respiratory comfort score was recorded at different times before and after intervention, make a comparison with the two groups in the incidence of hypoxemia, secondary intubation and other complications.Results:Finally, 36 cases were included in the experimental group and 38 cases in the control group. After 2, 8, 24, 48, 72 h of extubation, the oxygenation index, PaO 2, SaO 2 were higher and PaCO 2, respiratory rate were lower in the experimental group compared to the control group, the differences were statistically significant ( t values were 2.02-9.00, all P<0.05). At 72 h after extubation, the pH value of the experimental group was 7.43 ± 0.08, which was higher than 7.38 ± 0.09 of the control group, and the difference was statistically significant ( t=2.44, P<0.05). At 24, 48, 72 h after extubation, the throat pain scores and oral nasal dryness symptom and sore throat symptom scores were (3.11 ± 1.53), (2.25 ± 0.57), (0.94 ± 0.14) points and (4.33 ± 1.08), (3.33 ± 0.68), (2.81 ± 0.43) points in the experimental group, lower than in the control group (5.24 ± 1.96), (3.58 ± 0.73), (2.18 ± 0.91) points and (6.00 ± 1.92), (5.39 ± 1.13), (4.79 ± 0.54) points, the differences were statistically significant ( t values were 3.46-5.21, all P<0.05). The incidence of hypoxemia, secondary intubation and intolerance were 2.8% (1/36), 2.8% (1/36) and 0 in the experimental group, lower than in the control group 26.3% (10/38), 21.1% (8/38) and 10.5% (4/38), the differences were statistically significant ( χ2=8.09, 5.78, 4.01, all P<0.05). Conclusions:De-escalation noninvasive positive pressure ventilation for obese patients with AAD can effectively improve oxygenation, reduce the incidence of hypoxemia and secondary intubation, and alleviate respiratory symptoms.
RESUMO
Objective To investigate the diagnostic accuracy of malignant tumor of 18F-fluorodeoxyglucose positron emission tomography/computed tomograprhy (18F-FDG PET/CT) imaging in the patients of elevated serum carbohydrate antigen 19-9 (CA19-9) and its correlation with maximum standardized uptake value (SUVmax) and serum CA19-9 level.Methods Whole-body 18F-FDG PET/CT scan was performed in 149 patients with elevated serum CA19-9 level without the history of malignancy.Blood sample was drawn in each case for CA19-9 assay two weeks or less before the performing PET/CT.Final diagnoses were confirmed by operation/biopsy pathological results and clinical follow-ups.Results Among the 149 patients,64 cases were finally diagnosed as malignancies and 85 cases of non-malignancy diseases.The true positive of the diagnoses by 18F-FDG PET/CT was 60 cases,the false positive 13 cases,the true negative 72 cases,the false negative 4 cases.The accuracy of diagnosis of malignant tumor with elevated serum CA19-9 was 43.0％,while elevated serum CA19-9 combined with 18F-FDG PET/CT imaging was 88.6％,with statistically significant difference (x2 =59.882,P ＜ 0.05).The serum CA19-9 was divided into 4 groups according to the different levels of 37-100 U/ml,100-500 U/ml,500-1000 U/ml and ＞ 1 000 U/ml.The diagnostic accuracy of each group of PET/CT was 94.5％,84.9％,81.3％ and 88.0％,respectively.There was no statistically significant difference between each group (x2 =3.503,P ＞ 0.05).The area under the curve (AUC) of the serum CA19-9 for the diagnosis of malignant tumor (ROC) was 0.726,and the sensitivity and specificity of the diagnostic boundary value of 152.75 U/ml were 70.3％ and 68.2％,respectively.The AUC of SUVmax in diagnosis of malignant tumor was 0.742,the best cutoff value was 6.95,and the sensitivity and specificity were 73.3％,69.2％ respectively.Conclusions 18 F-FDG PET/CT is useful for detecting malignant tumors combined with serum tumor marker CA19-9.The patients with elevated serum CA19-9 are necessary to do PET/CT imaging,especially serum CA19-9 ＞ 152.75 U/ml.And it should be considered malignant tumor when SUVmax ＞ 6.95.
RESUMO
Objective To explore the cost-effectiveness and clinical effect of three platinum based chemotherapy regiments for advanced non small cell lung cancer (NSCLC).Methods 100 patients who were diagnosed as NSCLC,were randomly divided into four groups.The group Ⅰ received NP which was given NVB and DDP.The group Ⅱreceived GP which was given GEM and DDP.The group Ⅲ received TP which was given taxotere and DDP.The clinical effect,adverse reaction and cost effectiveness of the three groups were assessed.Results The clinical effective rates of the three groups were 31.43%,36.36%,37.50% from Ⅰ to Ⅲ group.The adverse events of the group Ⅰ and group Ⅱ were more than those of the group Ⅲ.In the adverse effects of treatment,the major cytotoxicity was digestive reaction and leukopenia in the two groups,but they were tolerable.The ratios of cost effectiveness in the four groups were 550.22yuan,556.48yuan,583.23yuan from Ⅰ to Ⅲ group.Conclusion The NP group is the best one in total cost.
RESUMO
OBJECTIVE:To provide reference for the application of position number in the pharmacy drug management. METHODS:Three-dimensional coding method was used for coding the position number. The mentioned method was combined with hospital information management system (HIS) for the out of storage,deployment and inventory. Memory field assumptions method was used to compare the size of field memorized by pharmacist in inpatient pharmacy before and after management of posi-tion number. Sampling controlled trial was conducted to compare the drugs deployment time and walking distance of pharmacists in inpatient pharmacy and drug storehouse before and after coding management of position number. RESULTS:After management of coding management in inpatient pharmacy,the memory required field was decreased from 1 028 to 25,deployment time of pharma-cists was decreased from(36.57±0.82)min to(24.20±0.33)min,and the walking distance was decreased from(79.17±0.29)m to(38.59±0.56)m. After management of coding management in drug storehouse,deployment time of pharmacists was decreased from(61.86±0.44)min to(47.18±0.63)min,and the walking distance was decreased from(129.53±0.58)m to(68.97±0.32) m. CONCLUSIONS:The drug coding management of position number can improve the deployment efficiency and reduce the brain and physical quantity of pharmacists.
