ABSTRACT
Objective To analyze the the incidence of sedation-related adverse events occurring during percutaneous microwave ablation(PMWA)under deep sedation,and to identify the risk factors for hypoxemia,hypertension and body movement response.Methods The clinical data of 506 patients with liver cancer,who received PMWA under deep sedation at the First Affiliated Hospital of Nanjing Medical University of China between December 2018 and December 2022,were retrospectively analyzed.The sedation-related adverse events including hypoxemia,hypertension and body movement response were recorded.Univariate analysis and multivariate logistic regression analysis were used to assess the risk factors for hypoxemia,hypertension and body movement response.Results After excluding 20 patients whose clinical data were incomplete,the final study sample consisted of 486 patients.After deep sedation,hypotension occurred in 5 patients(1％),and the incidences of hypoxemia,hypertension and body movement response were 13.8％,13.2％and 25.5％respectively.No patient required urgent endotracheal intubation and no cardiovascular complications occurred.The body movement response did not increase the complications of PMWA.Multivariate analysis revealed that age ≥65 years(OR=1.034,P=0.033),BMI＞30 kg/m2(OR=1.865,P=0.039),and Child-Pugh grade B/C(OR=1.113,P=0.046)were the risk factors for hypoxemia.The ablation zone contacting the parietal peritoneum(OR=2.536,P＜0.01),ablation zone contacting the diaphragm(OR=1.795,P=0.001),and ablation zone contacting the adrenal gland(OR=1.581,P＜0.01)were the risk factors for hypertension.The ablation zone contacted the parietal peritoneum(OR=2.831,P＜0.01)and ablation zone contacted the diaphragm(OR=2.213,P=0.026)were the risk factors for body movement response.Conclusion For the treatment of liver cancer,PMWA under deep sedation is clinically safe and effective.The age ≥ 65 years,BMI＞30kg/m2,and Child-Pugh grade B/C are the risk factors for hypoxemia.The ablation zone contacting the parietal peritoneum,the diaphragm or the adrenal gland are the risk factors for hypertension.The ablation zone contacting the parietal peritoneum or the diaphragm are the risk factors for body movement response.(J Intervent Radiol,2023,32:1202-1206)
ABSTRACT
Objective To assess the psychometric potential of the Montreal Cognitive Assessment Scale-Beijing (MoCA-BJ) as a screening instrument for mild cognitive impairment (MCI) in older adults in Wuhan communities of central China. Methods MoCA-BJ and Mini-Mental State Examination (MMSE) were adopted to assess the MCI of 381 older adults from 13 communities in Wuhan in 2015. Confirmatory factor analysis was conducted to evaluate the construct validity of MoCA-BJ, and the relationship between all aspects of cognitive function and MoCA different dimensions. Results MoCA-BJ had acceptable reliability (w=0.76), and MoCA-BJ and MMSE estimation results were highly correlated (r=0.73, P＜0.01). By comparing three measurement models through confirmatory factor analysis, we found that the MoCA-BJ scale had two factors (F1: visual space executive function, F2: memory-based other cognitive functions) in model 3, fit degree of which was higher than model 1 by one factor, and there was a statistically significant difference in the number of factors between model 1 and model 3 (χ2dif=8.73,P＜0.01). Conclusions The MoCA-BJ has two underlying factors that respectively represent two highly correlated but distinct factors, cognition and visual-spatial. Uninformative items should be revised with culturally sensitive items and the cut-off point for mild impairment should also be altered.
