ABSTRACT
Objective:To explore the changes of intracranial pressure in intensive care unit (ICU) patients during the occurrence and evolution of delirium by using bedside ultrasound to measure the optic nerve sheath diameter (ONSD) to evaluate intracranial pressure.Methods:A retrospective observational study was conducted. Adult patients who developed delirium during hospitalization in the general ICU of Beihai People's Hospital from October 2020 to November 2021 were enrolled, and patients who did not have ultrasonographic ONSD records within 24 hours after the diagnosis of delirium were excluded. The ONSD measured before delirium was recorded as ONSD 0, the ONSD measured within 24 hours of the onset of delirium recorded as ONSD 1, and the ONSD reexamined after ONSD 1 recorded as ONSD 2. Patients were divided into intracranial hypertension group (ONSD 1 > 5 mm) and normal intracranial pressure group (ONSD 1 ≤ 5 mm) according to the size of ONSD 1. According to the outcome of delirium, the patients were divided into cured, improved, and non-improved groups. The reduction ratio of ONSD 2 to ONSD 1 in the three groups were calculated and compared. Pearson correlation test was used to analyze the correlation between fluid balance and ONSD changes after delirium. Results:There were 43 patients, including 40 cases in the intracranial hypertension group (the incidence rate was 93.0%), 3 cases in the normal intracranial pressure group, 23 cases were cured, 13 cases were improved, and 7 cases were not improved. In the intracranial hypertension group, 11 cases had ONSD 0 and ONSD 1 records, and ONSD 1 was significantly higher than ONSD 0 [mm: 5.88±0.61 vs. 5.34±0.57, 95% confidence interval (95% CI) -0.85 to -0.23, P = 0.003]. The reduction ratio of ONSD 2 to ONSD 1 in the cured group was significantly higher than that in the improved group and the non-improved group [(12.04±6.20)% vs. (5.68±4.10)%, (0.17±3.96)%; 95% CI were 2.37 to 10.33, 6.41 to 17.31, P values were 0.003 and 0.000, respectively]. The correlation analysis showed that the reduction ratio of ONSD 2 to ONSD 1 was negatively correlated with fluid balance ( r = -0.42, 95% CI was -0.66 to -0.10, P = 0.012). Conclusions:The incidence of intracranial hypertension in ICU delirium patients is high. A more pronounced decrease in intracranial pressure predicts a better delirium outcome. Dynamic ONSD measurement can provide valuable information for the prevention and treatment of delirium.
ABSTRACT
Objective:To investigate the effect of thromboelastography (TEG) combined with point-of-care ultrasound (POCUS) guidance on the prevention of internal jugular vein catheterization related thrombosis.Methods:The patients who required internal jugular vein catheterization admitted to the department of critical medicine of Beihai People's Hospital from December 2018 to April 2020 were enrolled. Patients were divided into two groups according to the random number table method. For the combined cathetherization group, ultrasound was used to examine bilateral internal jugular veins before catheterization. The larger diameter and better filled vein and site were selected for puncture. If both internal jugular veins were not fulfilled well, puncture were performed after fluid administration. At the same time, anticoagulant, antiplatelet or reducing blood viscosity drugs were used according to coagulation function and bleeding risk under the monitoring of TEG. The hemodynamic state of the internal jugular vein was monitored by ultrasound every day. If the vein collapsed or the blood flow was slow, the cause should be tried to be found and improved. Once thrombosis was found, the catheter should be removed. For the routine cathetherization group, the right side internal jugular vein was prior to be punctured according to body surface symbols. The other treatment of the two groups were the same as routine treatment. The conditions of thrombosis and bleeding were recorded.Results:Ninety-seven patients were selected, 51 cases in the combined cathetherization group and 46 cases in the routine cathetherization group. There was no significant differences in gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), risk of deep vein thrombosis score (Caprini), CRUSADE bleeding risk score, the proportion of high bleeding risk, disease types, the proportion of coagulation disorder and catheterization time between the two groups, but the anticoagulation treatment proportion in the combined cathetherization group was higher than that in the routine cathetherization group (66.7% vs. 30.4%, P < 0.01). The incidence of thrombosis in the combined cathetherization group was lower than that of the routine cathetherization group (39.2% vs. 78.3%, P < 0.01), and the thrombus of the combined cathetherization group was smaller than that of the routine cathetherization group [cm 3: 0.077 (0.047, 0.089) vs. 0.341 (0.070, 0.378), P < 0.01]. There were no major bleeding events in the two groups. Conclusion:Based on TEG and POCUS, the antithrombotic bundles can reduce the incidence of thrombosis after internal jugular vein catheterization and the thrombus size, and does not increase the risk of bleeding, which is worthy of clinical application.
ABSTRACT
Objective To investigate the relationship between metabolic syndrome (MS) and education level in Su-Xi-Chang area to provide evidence for healthcare policy making. Methods A clustered sampling of 6798 subjects from Su-Xi-Chang areas of Jiangsu Province was included. Questionnaires and physical examinations were completed to collect clinical data. Logistic regression was used to analyze weather education level could be an independent risk factor of MS. Results Significant differences were found in waist circumstance (WC) ,systolic blood pressure (SBP) and fasting blood glucose (FBG) among participants with different education level. Significant differences were also existed in triglyceride and diastolic blood pressure (DBP) between subjects with higher and lower education level ( P＜0. 05 ). In single-factor or multivariate analysis, education level was negatively correlated with the prevalence of MS (P＜0. 05 ). Conclusions Education level may be an independent risk factor of MS. People with low and moderate education level have higher risk of MS. Therefore,it is recommended that health-related information should become an integral part of the compulsory education system.

Objective: To establish quality standard on Qinggan Granules (Radix Actinidiae valvatas, Radix Scutellariae, Rhizoma Atractylodis Macrocephalae, Badix Bupleuri, etc.). Methods: Radix Actinidiae valvatae, Radix Scutellariae, Rhizoma Atractylodis Macrocephalae and Radix Bupleuri were identified by TLC, and the content of Baicalin was determined by dual wavelength TLC scanning. Results: Baicalin showed a linear relationship at the range of 0.55～4.4?g, the average recovery was 102.9%. Conclusion: Method is simple, quick and good reproducible.
