in order to maintain a normal temperature range.

Objective To evaluate feasibility and reliability of using Simplified Acute Physiology Score Ⅱ (SAPS Ⅱ)in predicting mortality in critically ill patients with neurological diseases.Methods All 653 patients hospitalized in neurological intensive care unit (N-ICU) from Jan 2005 to Dec 2007 were retrospectively studied.SAPSⅡ scores were scaled upon admission at 24,48 and 72 h,and possibility of hospital mortality (PHM) was calculated based on SAPS Ⅱ score.Neurological diseases diagnosis made initially at time of hospitalization was classified into five categories:intracranial hemorrhage,cerebral infarction,neurologic infection,neuromuscular diseases and other neurologic diseases.At each of four time points,the SAPSⅡscores were compared between the survival group and death group,and the relationship of SAPS Ⅱ score and prognosis were analyzed.The calibration of the SAPS Ⅱ were accessed with the Hosmer-Lemeshow goodness-of-fit chi-squared statistic and the discrimination with area under the receiver operating characteristic curve (AUROC).Multivariate logistic regression was used to analyze the relationship between disease category and prognosis.Results SAPS Ⅱ scores in the death group (46.53±12.22,47.28±13.84,48.58±14.18 and 49.06±14.61)at each time point were significantly higher than those in the survival group (34.70±11.78,30.28±12.24,29.79±12.36 and 29.69±12.96;t=11.12,14.02,14.43 and 13.49 at 0,24,48 and 72 h,respectively,P＜0.01).Furthermore,univariate logistic regression analyses demonstrated that SAPS Ⅱ score was correlated with prognosis (OR=1.080,1.100,1.109,1.100 at 0,24,48 and 72 h,respectively,P＜0.01).The scores at 48 and 72 h were more accurate in predicting mortality.SAPS Ⅱ had good calibration at each time points (x2=5.305,7.557,6.369 and 8.540,P＞0.05),however,the consistency of expected mortality with observed mortality was satisfactory only at 48 and 72 h(82.6%,83.4%),so was the discrimination ( AUROC=0.825,0.847 respectively).There was no correlation between disease categories and outcome.Conclusion SAPS Ⅱ scoring,best evaluated at 48 and 72 h after hospitalization,can be used as a reliable predictor of probability of mortality in patients hospitalized in N-ICU and prediction can be applied in these patients with all different neurology diseases.

Objective:To explore the clinical characteristics, therapeutic effect and prognosis of movement disorders in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis.Methods:The prospectively collected data of hospitalized 163 patients with anti-NMDAR encephalitis admitted to Xuanwu Hospital, Capital Medical University from June 2012 to October 2019 were analyzed. According to the presence of movement disorders, the patients were divided into movement disorders group (75 cases, 46.0%) and non-movement disorders group (88 cases, 54.0%). Patients were followed up for six months and 12 months after immunotherapy. The clinical manifestations, auxiliary examinations, treatment and prognosis of the two groups were compared.Results:Among 163 patients with anti-NMDAR encephalitis, 91 patients (55.8%) were male and 72 patients (44.2%) were female, with an age of 26(19, 34) years. In the 75 patients of the movement disorders group, 50 patients (66.7%) presented with orofacial dyskinesia, 45 patients (60%) with limb stereotypies, 28 patients (37.3%) with choreoathetosis, nine patients (12.0%) with ballism, seven patients (9.3%) with bradykinesia, five patients (6.7%) with tremor, and 13 patients (17.3%) with status dystonicus. Compared with the non-movement disorders group, the movement disorders group had a higher proportion of ovarian teratoma (14.7% vs 3.4%), modified Rankin Scale score of 3-5 before immunotherapy (76.0% vs 33.0%), abnormal electroencephalogram (89.3% vs 77.3%), increased lumbar puncture pressure (53.3% vs 34.1%), cerebrospinal fluid (CSF) pleocytosis (73.3% vs 51.1%), strong positive NMDAR antibody of CSF (44.0% vs 25.0%), admitting to intensive care unit (60.0% vs 9.1%), treated with intravenous immunoglobulin (80.0% vs 40.9%), plasma exchange (36.0% vs 3.4%), and immunosuppressive therapy (37.2% vs 17.0%); had shorter days from the onset to the beginning of immunotherapy [20(10, 33) d vs 35(15, 77) d]; had longer days from the beginning of immunotherapy to the improvement [34(20, 60) d vs 20(15, 35) d]; and there were significant differences of above items between the two groups ( P<0.05). There was no significant difference in the prognosis and relaps between the two groups at six and 12 months after immunotherapy. Conclusions:Nearly a half of patients with anti-NMDAR encephalitis had movement disorders with multiple phenotypes. The severity of movement disorders was related to the severity of the disease. After active immunotherapy and symptomatic treatment, movement disorders improved with the improvement of primary disease in majority of patients.

Objective:To investigate the preventive effect of different intermittent pneumatic compressiondevices (IPC) schemes on deep vein thrombosis (DVT) of lower extremity in patients with status epilepticus (SE), to provide nursing basis for rational application of IPC in early admission of SE patients.Methods:A similar experimental study was conducted and 76 SE patients in the intensive care unit of the Department of Neurology, Xuanwu Hospital, Capital Medical University from January 2018 to May 2022 were selected by convenience sampling method. The 35 SE patients hospitalized from January 2018 to February 2020 were included in the control group, and 41 patients hospitalized from March 2020 to May 2022 were included in the intervention group.Both groups were given anti-seizure medications (ASMs) to actively control seizures after admission.IPC application frequency and duration in control group were twice a day, 1 hour each time; the frequency of IPC application in the intervention group was once a day for greater than or equal to 12 hours each time.The incidence of lower limb DVT, epileptic seizure, abnormal electroencephalogram discharge and coagulation index related to lower limb DVT formation were compared between the two groups.Results:There was no significant difference in the indexes of fibrinogen, D-dimer and thrombin time between the two groups of SE patients at admission ( P>0.05). At discharge, the indexes of fibrinogen, D-dimer and thrombin time were (4.02 ± 1.71) g/L, 7.06(5.33, 15.01) mg/L and 10.22(7.53, 14.42) s in the intervention group respectively, which were lower than (4.98 ± 1.62) g/L, 11.92(5.75, 15.26) mg/L and 17.96(13.21, 28.14) s in the control group, the differences were statistically significant ( t = 3.03, Z = 4.32, 1.56, all P<0.05). The DVT incidence rate was 62.86% (22/35) in the control group, and the intervention group was 12.20% (5/41). The difference was statistically significant ( χ2 = 21.59, P<0.01). Conclusions:On the basis of effective control of clinical seizures in SE patients treated with ASMs, early IPC use and daily treatment time at least 12 hours can avoid induced seizures, reduce the formation and risk of lower extremity DVT, and improve blood hypercoagulability.

Objective To study the correlation of quantitative electroencephalography (qEEG) parameters with outcomes of adults who sustained coma after cardio-pulmonary resuscitation.Methods The clinical data of coma patients after cardio-pulmonary resuscitation,admitted to our hospital from March 2008 to August 2014 were retrospectively analyzed.Glasgow coma scale (GCS) was performed.EEG was registered and recorded at least once within 7 d of coma after cardio-pulmonary resuscitation:electrodes were placed according to the international 10-20 system,using a 16-channel lay out.The qEEG parameters defined as burst suppression ratio (BSR),brain symmetry index (BSI),[delta+theta]/[alpha+beta] ratio (DTABR) were analyzed at the same time.Follow-up was performed 3 months after onset and the outcomes of these patients were assessed by Glasgow outcome scale (GOS).The correlations of GOS scores with qEEG parameters were analyzed.Results Sixty patients with GCS scores-＜ 8 after cardio-pulmonary resuscitation were included.BSR1 and BSR2 were negatively correlated with GOS scores 3 months after onset (r=-0.723,P=0.000;r=-0.651,P=0.000);DTABR was positively correlated with GOS scores 3 months after onset (r=0.270,P=0.037).BSI and DTABR were not correlated with GCS scores.BSR1 and BSR2 were negatively correlated with GCS scores (r=-0.562,P=0.000;r=-0.429,P=0.001).Conclusion The qEEG parameters are correlated with outcomes after cardio-pulmonary resuscitation.

BACKGROUNDThe brain death confirmation tests occupy a different position in each country's diagnostic criteria (or guideline); the choices of tests are also different. China brain death criteria include clinical judgment and confirmation tests. This study aimed to confirm the preferred confirmatory test and complementary confirmatory tests.

METHODSWe did a clinical brain death determination on deep coma patients, and then divided them into brain death group and non-brain death group. According to the Chinese standards for determining brain death, both the groups accepted confirmatory tests including electroencephalograph (EEG), somatosensory evoked potentials (SEP), and transcranial Doppler (TCD). The sensitivity, specificity, false positive rate, and false negative rate were calculated to evaluate the accuracy of the confirmatory tests.

RESULTSAmong the 131 cases of patients, 103 patients met the clinical criteria of brain death. Respiratory arrest provocation test was performed on 44 cases and 32 cases (73%) successfully completed and confirmed that they have no spontaneous breathing. Of the three confirmation tests, EEG had the highest completion rate (98%) and good sensitivity (83%) and specificity (97%); TCD had followed completion rate (54%) and not good sensitivity (73%) and specificity (75%); SEP had the lowest completion rate (49%), good sensitivity (100%), and not good specificity (78%). After the combination of SEP or TCD with EEG, the specificity can increase to 100%.

CONCLUSIONSThe completion rate of respiratory arrest provocation test remains a problem in the clinical diagnosis of brain death. If the test cannot be completed, whether to increase a confirmatory test is debatable. SEP had an ideal sensitivity, and the specificity will reach 100% after combining with TCD or EEG. When a confirmed test was uncertain, we suggest increasing another confirmatory test.
