Effects of exogenous factors on spatial accuracy in neurosurgery

The study aimed to assess the effect of exogenous factors such as surgeon posture, surgical instrument length, fatigue after a night shift, exercise and caffeine consumption on the spatial accuracy of neurosurgical manipulations. For the evaluation and simulation of neurosurgical manipulations, a testing device developed by the authors was used. The experimental results were compared using nonparametric analysis (Wilcoxon test) and multivariate analysis, which was performed using mixed models. The results were considered statistically significant at p < 0.05. The study included 11 first-year neurosurgery residents who met the inclusion criteria. Hand support in the sitting position (Wilcoxon test p value = 0.0033), caffeine consumption (p = 0.0058) and the length of the microsurgical instrument (p = 0.0032) had statistically significant influences on the spatial accuracy of surgical manipulations (univariate analysis). The spatial accuracy did not significantly depend on the type of standing position (Wilcoxon test p value = 0.2860), whether the surgeon was standing/sitting (p = 0.1029), fatigue following a night shift (p = 0.3281), or physical exertion prior to surgery (p = 0.2845).When conducting the multivariate analysis, the spatial accuracy significantly depended on the test subject (p < 0.0001), the use of support during the test (p = 0.0001), and the length of the microsurgical instrument (p = 0.0397). To increase the spatial accuracy of microsurgical manipulations, hand support and shorter tools should be used. Caffeine consumption in high doses should also be avoided prior to surgery.     

Effect of hypoxia on mortality and disability in traumatic brain injury according to shock status: A cross-sectional analysis

ObjectivesThis study aimed to test the association between hypoxia level and outcomes according to shock status in traumatic brain injury (TBI) patients.MethodsAdult TBI patients transported by emergency medical services in 10 provinces were enrolled. Hypoxia was a main exposure; three groups by oxygen saturation (SaO2, non-hypoxia (≥94%), mild hypoxia (90 ≤ SaO2 < 94%)), and severe hypoxia (<90%). Shock status (<systolic blood pressure 90 mmHg) was an interactive exposure. The outcomes were hospital mortality and worsened disability (a 2-point increase of Glasgow Outcome Scale). Multivariable logistic regression was used to calculate the adjusted odds (AORs) with 95% Confidence intervals (CIs).ResultsOf the 6125 patients, the mortality/disability rates were 49.4%/69.0% in severe hypoxia, 30.7%/46.9% in mild hypoxia, and 18.5%/27.5% in normoxia (p < 0.0001). Mortality/disability rates were 47.1%/57.1% in shock status and 20.5%/31.4% in non-shock status (p < 0.0001). AORs (95% CIs) for worsened disability/mortality compared with normoxia (reference) were 3.23 (2.47–4.21)/2.24 (1.70–2.96) in patients with severe hypoxia and 2.11 (1.63–2.74)/1.84 (1.39–2.45) in those with mild hypoxia. AORs (95% CIs) for worsened disability/mortality was 1.58 (1.20–2.09)/1.33 (1.01–1.76) by severe hypoxia than normoxia in patient with only non-shock status in the interaction analysis.ConclusionsThere was a trend toward worsened outcomes with mild and severe hypoxia in patient with and without shock, however, the only met statistical significance for patients with both severe hypoxia and non-shock status.     

广州市某三级甲等医院35岁以上护士健康体检状况分析

目的探讨广州市某三级甲等医院35岁以上护理人员的健康体检状况。方法回顾性分析我院2017年35岁以上护理人员健康体检结果,按年龄段分为35~44岁组和45~55岁组,并将科室按风险级别分为Ⅰ类、Ⅱ类、Ⅲ类,统计分析体检结果异常率,并将其血脂与常模进行比较。结果35岁以上在职护理人员的体检结果异常率为57.4%,其中45~55岁处于Ⅰ类风险科室的护士体检异常率最高;35~44岁组、45~55岁组、常模血脂指标中总胆固醇(CHOL)、甘油三脂(TG)、低密度脂蛋白(LDL-C)比较,差异均有统计学意义(F=20.768,P<0.001;F=13.673,P<0.001;F=11.627,P<0.001),且45~55岁组的CHOL、TG、LDL-C值均高于35~44岁组。结论医院健康管理者应重视35岁以上在职护理人员的健康管理,尤其是45岁以上护理人员在血脂方面的监控和健康宣教。
