Diagnostic and predictive value of CT perfusion imaging in patient with traumatic brain injury / 实用放射学杂志

Objective To investigate the application value of CT perfusion imaging in patient with traumatic brain injury(TBI).Methods Thirty-seven patients with TBI were included retrospectively and divided into mild,moderate,and severe groups according to Glasgow coma scale(GCS)score.Perfusion parameters of the cerebral hemispheres on the injured side and the contralateral side of the level of basal ganglia were compared.After three months,the correlations between perfusion parameters and GCS score at baseline and Glasgow outcome scale-extended(GOSE)score at follow-up were further analyzed,respectively.Results The injured side of TBI patients showed hypo-perfusion compared with that of the contralateral side.The abnormal perfusion volumes of time to maximum of the residual function(Tmax)>10 s was significantly negatively correlated with GOSE score(ρ=-0.55,P=0.01),and could distinguish the good prognosis group from the poor prognosis group with GOSE score[area under the curve(AUC)=0.82,P= 0.01].In the group of patients undergoing decompressive craniectomy,the abnormal perfusion volumes of Tmax>4 s and Tmax>6 s were significantly associated with GCS score(ρ=0.61,P=0.01;ρ=0.53,P=0.03).Conclusion CT perfusion imaging may be useful in assessing the hemodynamics and severity of TBI,and in predicting the clinical prognosis.

Objective To explore the efficacy of early hyperbaric oxygen therapy(HBOT)combined with median nerve electrical stimulation(MNES)in the treatment of severe traumatic brain injury(sTBI)and its impact on hemodynamics,coma degree,and neurological function of patients.Methods A total of 78 patients with sTBI admitted to the General Hospital of Western Theater Command from March 2020 to October 2021 were selected as the research subjects.The patients were randomly divided into the control group and the observation group,with 39 patients in each group.The patients in both groups underwent basic treatments such as water,electrolyte and acid-base balance,nutritional support,anti-infection,and decompressive craniectomy.On this basis,patients in the control group received early HBOT,while patients in the observation group received both HBOT and MNES.Their clinical efficacy was compared between the two groups.Before and after treatment,dual-channel transcranial Doppler ultrasound was performed to detect hemodynamic indicators such as peak systolic blood flow velocity(Vs),mean blood flow velocity(Vm),and pulsatility index(PI)in the middle cerebral artery of patients in the two groups.The Glasgow Coma Scale(GCS)score was used to evaluate the degree of coma of patients in the two groups,the National Institutes of Health Stroke Scale(NIHSS)score was used to assess the neurological deficits of patients in the two groups,and the enzyme-linked immunosorbent assay was used to measure the levels of central nervous system specific protein(S100-β),glial fibrillary acidic protein(GFAP),and myelin basic protein(MBP).Complications during treatment of patients in the two groups were recorded,and their incidence was compared.Results The total effective rate of patients in the control and observation groups was 79.49％(31/39)and 92.31％(36/39),respectively.The total effective rate in the observation group was significantly higher than that in the control group(x2=8.971,P＜0.05).There was no significant difference in Vm,Vs,and PI between the two groups before treatment(P＞0.05).After treatment,the Vm and Vs in both groups were significantly higher than those before treatment,while the PI was significantly lower than that before treatment(P＜0.05);and the Vm and Vs in the observation group were signifi-cantly higher than that those in the control group,while the PI was significantly lower than that in the control group(P＜0.05).There was no significant difference in GCS and NIHSS scores between the two groups before treatment(P＞0.05).After treatment,the GCS score in both groups was significantly higher than that before treatment,while the NIHSS score was significantly lower than that before treatment(P＜0.05);and the GCS score in the observation group was significantly higher than that in the control group,while the NIHSS score was significantly lower than that in the control group(P＜0.05).There was no significant difference in S100-β,GFAP,and MBP levels between the two groups before treatment(P＞0.05).After treatment,the S100-β,GFAP,and MBP levels in both groups were significantly lower than those before treatment(P＜0.05),and the S100-β,GFAP,and MBP levels in the observation group were significantly lower than those in the control group(P＜0.05).During treatment,the incidence of complications in the control and observation groups was 23.08％(9/39)and 20.51％(8/39),respectively,showing no significant difference(x2=2.328,P＞0.05).Conclusion Early HBOT combined with MNES shows good efficacy in treating sTBI,which can effectively improve the patients'hemodynamic level,alleviate the severity of coma,enhance neurological function,and promote early recovery of consciousness,without increased risk of complications.

Comparison of effective optical zone and corneal high order aberration following small incision lenticule extraction for different degrees of myopia / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the effective optical zone(EOZ)and corneal high order aberrations(HOAs)after small incision lenticule extraction(SMILE)among low, moderate, and high myopic patients.METHODS:A total of 134 patients who had undergone SMILE at the Second People's Hospital of Foshan from February 2019 to February 2021 were recruited, with all right eyes enrolled. The patients were divided into low myopia group(SE >-3.00 D), moderate myopia group(-6.00 D< SE ≤-3.00 D), and high myopia group(SE ≤-6.00 D)according to the spherical equivalent(SE). The total HOA(tHOA), spherical aberration, coma, and EOZ were measured by Pentacam preoperatively and 1 mo postoperatively, and differences in tHOA, spherical aberration, coma, and EOZ among the three groups were analyzed.RESULTS: EOZ was smaller than programmed EOZ in all groups at 1 mo after SMILE. With the increase in corrected refractive error, the EOZ decreased further(P<0.05); The tHOA, spherical aberration, and coma were significantly higher than their corresponding preoperative values in all groups at 1 mo after surgery, and there were statistical differences in the spherical aberration of all the groups at 1 mo after surgery(P<0.05), except for that of the mild myopia group(P>0.05). The tHOA, spherical aberration and coma increased with corrected refractive errors; the difference in tHOA and spherical aberration was statistically significant among the three groups(all P<0.05). Coma in the high myopia group was significantly greater than that in the moderate myopia group and the mild myopia group(P<0.05). In addition, the coma in the moderate myopia group and the mild myopia group was not statistically significant(P>0.05).CONCLUSION: With the increase of the refractive power corrected by surgery, the postoperative EOZ reduced more after surgery, and the HOA of the cornea is increased; corneal HOA increases at 1 mo after SMILE.

Role of spherical aberration and coma in orthokeratology for myopia control / 国际眼科杂志(Guoji Yanke Zazhi)

As a highly prevalent global condition, myopia significantly impacts the ocular health of young individuals in China. Orthokeratology lens, as a rigid corneal contact lens, has demonstrated effective control over the progression of myopia; however, its mechanism of action remains incompletely elucidated. As one of the factors influencing visual acuity, higher-order aberrations will undergo marked changes after orthokeratology, with particular emphasis on the alterations in spherical aberrations and coma. The changes in corneal morphology induced by orthokeratology lead to significant positive increase in both spherical aberration and coma. Furthermore, the elevation of spherical aberration and coma demonstrates a negative correlation with the rate of axial length growth following orthokeratology. The interplay among spherical aberration, coma, defocus, accommodation, astigmatism, and pseudo-accommodation may constitute the underlying mechanism governing the control of myopia through orthokeratology.

Glasgow coma scale pupil score (GCS-P) and the hospital mortality in severe traumatic brain injury: analysis of 1,066 Brazilian patients / Escala de coma de Glasgow com resposta pupilar (ECC-P) e mortalidade hospitalar em traumatismo cranioencefálico grave: análise de 1.066 pacientes brasileiros

Abstract Background Pupil reactivity and the Glasgow Coma Scale (CCS) score are the most clinically relevant information to predict the survival of traumatic brain injury (TBI) patients. Objective We evaluated the accuracy of the CCS-Pupil score (CCS-P) as a prognostic index to predict hospital mortality in Brazilian patients with severe TBI and compare it with a model combining CCS and pupil response with additional clinical and radiological prognostic factors. Methods Data from 1,066 patients with severe TBI from 5 prospective studies were analyzed. We determined the association between hospital mortality and the combination of CCS, pupil reactivity, age, glucose levels, cranial computed tomography (CT), or the CCS-P score by multivariate binary logistic regression. Results Eighty-five percent (n = 908) of patients were men. The mean age was 35 years old, and the overall hospital mortality was 32.8%. The area under the receiver operating characteristic curve (AUROC) was 0.73 (0.70-0.77) for the model using the CCS-P score and 0.80 (0.77-0.83) for the model including clinical and radiological variables. The CCS-P score showed similar accuracy in predicting the mortality reported for the patients with severe TBI derived from the International Mission for Prognosis and Clinical Trials in TBI (IMPACT) and the Corticosteroid Randomization After Significant Head Injury (CRASH) studies. Conclusion Our results support the external validation of the CCS-P to predict hospital mortality following a severe TBI. The predictive value of the CCS-P for long-term mortality, functional, and neuropsychiatric outcomes in Brazilian patients with mild, moderate, and severe TBI deserves further investigation.

Resumo Antecedentes A reatividade pupilar e o escore da Escala de Coma de Glasgow (ECC) representam as informações clínicas mais relevantes para predizer a sobrevivência de pacientes com traumatismo cranioencefálico (TCE). Objetivo Avaliar a acurácia da ECC com resposta pupilar (ECC-P) como índice prognóstico para predizer mortalidade hospitalar em pacientes brasileiros acometidos por TCE grave e compará-lo com um modelo combinando ECC e resposta pupilar com fatores prognósticos radiológicos. Métodos Foram analisados dados de 1.066 pacientes com TCE grave de 5 estudos prospectivos. Foi determinada a associação entre mortalidade hospitalar e a combinação de ECC, reatividade pupilar, idade, níveis glicêmicos, tomografia computadorizada (TC) de crânio ou o escore ECC-P por regressão logística binária multivariada. Resultados Oitenta e cinco por cento (n = 908) dos pacientes eram homens. A média de idade foi de 35 anos e a mortalidade hospitalar geral foi de 32,8%. A AUROC (em português, Curva Característica de Operação do Receptor) foi de 0,73 (0,70-0,77) para o modelo utilizando o escore ECC-P e de 0,80 (0,77-0,83) para o modelo incluindo variáveis clínicas e radiológicas. O escore ECC-P mostrou acurácia semelhante na previsão da mortalidade relatada para pacientes com TCE grave derivados dos estudos International Mission for Prognosis and Clinical Trials in TBI (IMPACT, na sigla em inglês) e Corticosteroid Randomization After Significant Head Injury (CRASH, na sigla em inglês). Conclusão Nossos resultados apoiam a validação externa da ECC-P para prever a mortalidade hospitalar após um TCE grave. O valor preditivo da ECC-P para mortalidade a longo prazo, resultados funcionais e neuropsiquiátricos em pacientes brasileiros com TCE leve, moderado e grave precisam ser investigados.

Lesión cerebral post paro cardiaco: aspectos médicos, éticos y legales / Brain injury after cardiac arrest: Medical, ethical and legal issues disorder

RESUMEN Los sobrevivientes de la reanimación cardiopulmonar posterior a un paro cardiaco pueden tener un amplio rango de desenlaces y van desde recuperación neurológica completa, estado de vigilia sin respuesta, compromiso cognoscitivo diverso o la muerte. La lesión del tejido cerebral se presenta inmediatamente después del paro cardíaco, durante la reanimación y al retornar la circulación espontánea. La severidad y duración de la noxa isquémica determinarán el devenir neurológico. El examen clínico es el punto de partida en el abordaje multimodal del neuropronóstico. Se debe complementar con electroencefalograma, potenciales evocados somatosensoriales, neuroimágenes y biomar-cadores séricos. Entre un 10 a 15% de los pacientes con lesión cerebral posterior al paro cardiaco evolucionan hacia muerte por criterios neurológicos y son potenciales candidatos a la donación de órganos. Un retiro temprano de las terapias de sostenimiento de vida puede malograr la posibilidad de un potencial donante de órganos. Se puede estimar de manera temprana qué pacientes tienen mayor riesgo de evolucionar a muerte por criterios neurológicos. El neurólogo tiene un papel protagónico en el manejo de pacientes con lesión cerebral post paro cardiaco y sus decisiones tienen implicaciones éticas y legales.

ABSTRACT People who survive cardiopulmonary resuscitation (CPR) after cardiac arrest, have a wide range of outcomes including complete neurological recovery, coma, compromised cognitive function and death. Injury of the brain parenchyma starts immediately after a cardiac arrest, during CPR and return of spontaneous circulation. The severity of the ischemic injury will define the neurological outcome. The first step needed to determine a neurological prognosis is the clinical exam, with the help of electroencephalography, somatosensory evoked potentials, neuroimaging, and serum biomarkers. Between 10 and 15% of patients with brain injury after a cardiac arrest, develop brain death and become potential candidates for organ donation. A premature withdrawal of vital support can hamper the possibility of organ donation. The patients with higher risk of developing brain death can be identified early based on neurological criteria. The neurologist has a major role in the approach of patients with brain injury after cardiac arrest and the decision making with legal and ethical consequences.

Effects of Sevoflurane and Propofol on Neurological Recovery of Traumatic Brain Injury Patients in the Early Postoperative Stage: A Retrospective Cohort Study / 中国医学科学杂志(英文版)

Objective To investigate the effects of propofol and sevoflurane on neurological recovery of traumatic brain injury (TBI) patients in the early postoperative stage.Methods We retrospectively analyzed the clinical data of TBI patients who underwent craniotomy or decompressive craniectomy. Generalized additive mixed model (GAMM) was used to analyze effects of propofol and sevoflurane on Glasgow Coma Scale (GCS) on postoperative days 1, 3, and 7. Multivariate regression analysis was used to analyze effects of the two anesthetics on Glasgow Outcome Scale (GOS) at discharge.Results A total of 340 TBI patients were enrolled in this study. There were 110 TBI patients who underwent craniotomy including 75 in the propofol group and 35 in the sevoflurane group, and 134 patients who underwent decompressive craniectomy including 63 in the propofol group and 71 in the sevoflurane group. It showed no significant difference in GCS at admission between the propofol and the sevoflurane groups among craniotomy patients (β = 0.75, 95%CI: -0.55 to 2.05, P = 0.260). However, elevation in GCS from baseline was 1.73 points (95%CI: -2.81 to -0.66, P = 0.002) less in the sevoflurane group than that in the propofol group on postoperative day 1, 2.03 points (95%CI: -3.14 to -0.91, P < 0.001) less on day 3, and 1.31 points (95%CI: -2.43 to -0.19, P = 0.022) less on day 7. The risk of unfavorable GOS (GOS 1, 2, and 3) at discharge was higher in the sevoflurane group (OR = 4.93, 95%CI: 1.05 to 23.03, P = 0.043). No significant difference was observed among two-group decompressive craniectomy patients in GCS and GOS.Conclusions Compared to propofol, sevoflurane was associated with worse neurological recovery during the hospital stay in TBI patients undergoing craniotomy. This difference was not detected in TBI patients undergoing decompressive craniectomy.

The value of monitoring regional cerebral oxygen saturation in the prognosis assessment of comatose children in PICU / 中国小儿急救医学

Objective:To evaluate the value of monitoring regional cerebral oxygen saturation (rSO 2) in the prognosis of comatose children in pediatric intensive care unit (PICU). Methods:A total of 127 coma children who admitted to PICU at Henan Children′s Hospital from January 2019 to September 2021 were collected and divided into mild[Glasgow coma score(GCS): 13-15], moderate(GCS: 9-12) and severe coma(GCS: 3-8) groups according to GCS.A cerebral oxygen monitor was used to monitor the rSO 2 of all children before treatment, and on the 3rd, 7th and 14th day after treatment.The outcomes were assessed according to the pediatric cerebral performance category (PCPC), and the children were divided into recovery group(PCPC score: 1), disability group(PCPC score: 2-4) and poor prognosis group(PCPC score: 5-6). Multiple linear regression and receiver operating characteristic(ROC) curve were used to analyze the correlation between rSO 2 and PCPC score. Results:rSO 2 in mild, moderate and severe coma groups before treatment were (78.06±3.21)%, (66.07±6.05)%, and (52.87±6.49)%, respectively ( F=209.263, P<0.05). rSO 2 before treatment was positively correlated with GCS( r=0.806, P<0.05). There were significant differences in rSO 2 among recovery group, disability group and poor prognosis group before treatment and that on the 3rd, 7th and 14th day after treatment ( P<0.05). Notably, rSO 2 in recovery group was higher than that in disability group, and rSO 2 in disability group was higher than that in poor prognosis group.The rSO 2 of three groups showed an increasing trend over time ( P<0.05). Multiple linear regression analysis showed that rSO 2 on the 7th and 14th day of treatment were independent prognostic factors ( OR -0.042, 95% CI -0.082~0.003, P<0.05; OR -0.047, 95% CI -0.094~0.000, P<0.05). ROC analysis showed that rSO 2 on the 7th day of treatment had a relatively higher prognostic value for children in coma, and the area under the ROC curve for predicting the prognosis of abnormal brain function and no wakefulness were 0.741 and 0.746, respectively. Conclusion:Monitoring rSO 2 has predictive value for the prognosis of brain function of coma children in PICU, in which the prognostic value of rSO 2 on the 7th day after treatment is relatively higher and can be used as a reference index for prognosis assessment of coma children in PICU.

Objective:To investigate the clinical diagnosis and prognosis in patients with emergency septic encephalopathy.Methods:Case data of 131 patients with septic encephalopathy admitted to the emergency department of Chuiyangliu Hospital Affiliated to Tsinghua University from January 2020 to December 2021 were selected and divided into survival group and death group. Logistic regression was used to analyze the risk factors affecting diagnosis, treatment and prognosis in patients with septic encephalopathy. Receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of each indicator in patients with septic encephalopathy.Results:The mean arterial pressure (MAP) and pH level in the death group were lower than those in the survival group, while the C reactive protein (CRP), troponin T (TNI), D-dimer, lactic acid, creatinine, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, Sequential Organ Failure Assessment (SOFA), proportion of ventilator support, proportion of vasoactive drug use in the death group were higher than those in the survival group, with statistically significant difference (all P<0.05). Multivariate logistic regression analysis showed that APACHEⅡ score ( OR=1.290, 95% CI: 1.121-1.485, P<0.001), SOFA score ( OR=1.447, 95% CI: 1.183-1.796, P<0.001), the proportion of vasoactive drug use ( OR=18.720, 95% CI: 4.486-78.108, P<0.001) could predict the prognosis of patients with septic encephalopathy, and the area under the curve (AUC) was 0.823, 0886, 0.787. Conclusions:Elderly age and underlying brain diseases are important factors in the occurrence of septic encephalopathy. APACHE Ⅱ score, SOFA score, and the proportion of vasoactive drug use can predict the prognosis of patients with septic encephalopathy.

Soluble growth stimulating gene protein 2 in the diagnosis and treatment of traumatic brain injury / 中国基层医药

Objective:To investigate the correlation between soluble growth stimulating gene protein 2 (sST2) and the severity of traumatic brain injury (TBI) and its value in the diagnosis of traumatic brain injury.Methods:The clinical data of 110 patients with traumatic brain injury who were treated in The First Affiliated Hospital of University of Science and Technology of China (Anhui Province Hospital) from July 2022 to December 2022 were retrospectively analyzed. These 110 patients were included in the observation group. An additional 62 patients without traumatic brain injury who concurrently received treatment in the same hospital were included in the control group. In the observation group, patients were divided into a severe group [Glasgow Coma Scale (GCS) score 3-8 points), a moderate group (GCS score 9-12 points), and a mild group (GCS score 13-15 points) according to the GCS score. Serum sST2 levels were measured using enzyme-linked immunosorbent assay (ELISA) within 24 hours after injury in each group. Serum sST2 levels were compared between the observation group and the control group. Serum sST2 levels were compared among patients with severe, moderate, and mild TBI in the observation group to analyze the correlation between serum sST2 levels and the GCS score. The efficacy of serum sST2 levels in the diagnosis of TBI was evaluated using the receiver operating characteristic curve (ROC curve).Results:Serum sST2 levels in the observation group were 96.25 (48.05, 200.00) μg/L, which were significantly higher than 25.45 (19.78, 40.46) μg/L in the control group ( Z = -8.19, P < 0.05). Serum sST2 levels in pastients with severe TBI were slightly, but not significantly, higher than those in patients with moderate TBI ( P > 0.05), and serum sST2 levels in patients with severe and moderate TBI were significantly higher than those in patients with mild TBI ( Z = -5.20, Z = -4.40, both P < 0.05). There was a significant difference in sST2 levels among patients with mild, moderate and severe TBI ( H = 36.88, P < 0.05). In the observation group, serum sST2 levels within 24 hours after surgery were significantly negatively correlated with GCS score within 24 hours after admission ( rs = -0.561, 95% CI: -0.680~-0.413, P < 0.001). As serum sST2 levels increased, GCS scores showed a decreasing trend. Serum sST2 levels can be used as a prognostic indicator for TBI. Serum sST2 levels within 24 hours after injury can serve as a risk factor for TBI ( β = 0.042, OR = 1.043, 95% CI: 1.026-1.061, P < 0.001). The serum sST2 levels within 24 hours after injury have good diagnostic efficacy for TBI (area under the curve = 87.5%, 95% CI: 0.825-0.926, P < 0.001). Conclusion:The measurement of serum sST2 levels has a high value in the evaluation of the severity of TBI and prognosis, which is crucial for developing personalized treatment strategies for TBI.

Video-electroencephalogram follow-up in internal nuclear inclusion disease:a case report / 中国神经精神疾病杂志

Methods: One hundred thirty-seven patients with ADSOHS hospitalized in our hospital from January 2009 to December 2018 were selected as the research object. Long-term follow-up results, complications, mortality, and changes of cardiac function before and after operation were used to explore the value of Sun's operation. Results: The length of stay in intensive care unit of these 137 patients ranged from 9.5 to 623.75 hours (average of 76.41±97.29 hours), auxiliary ventilation time ranged from 6.0 to 259.83 hours (average of 46.16±55.59 hours), and hospital stay ranged from six to 85 days (average of 25.06±13.04 days). There were seven cases of postoperative low cardiac output, 18 cases of coma and stroke, and six cases of transient neurological dysfunction. A total of 33 patients died; 19 patients died during the perioperative period, 18 died during Sun's operation and one died during other operation; and 14 patients died during follow-up (January 2021), 12 cases of Sun's operation and two cases of other operations. Conclusion: ADSOHS treatment strategy is of high application value, and the risk of neurological complications and mortality is low. The main risk factors are postoperative low cardiac output, coma, stroke, and transient neurological dysfunction. The extracorporeal circulation time is relatively long. Short- and long-term follow-up effects are good, and it is worthy of clinical promotion.

The new prognostic factor in pre-intubation follow-up of critically ill patients: integrated pulmonary index monitoring

SUMMARY OBJECTIVE: The objective of this study was to identify the integrated pulmonary index in the follow-up of non-intubated critically ill patients in the emergency department and its efficacy in deciding on advanced airway application in comparison with the Glasgow Coma Scale. METHODS: This is a prospective, single-center, methodological study. In our study, we recorded the demographic characteristics, Glasgow Coma Scale, and the integrated pulmonary index of 90 patients with respiratory failure who were followed up in the emergency department between June 1, 2019 and September 1, 2019, and we compared the results of Glasgow Coma Scale and integrated pulmonary index in making the endotracheal intubation decision. RESULTS: Endotracheal intubation was applied to 30% of the 90 patients included in the study. The area under the curve was calculated as 0.906 for integrated pulmonary index and 0.860 for Glasgow Coma Scale in predicting endotracheal intubation. There was no significant difference between the area under the curves of integrated pulmonary index and Glasgow Coma Scale. According to the best cutoff values determined in the estimation of endotracheal intubation, sensitivity was 74.07% and specificity was 95.24% for integrated pulmonary index, and sensitivity was 74.07% and specificity was 85.71% for Glasgow Coma Scale. CONCLUSION: The integrated pulmonary index monitoring provides an objective evaluation in the follow-up of critically ill patients with spontaneous breathing in the emergency department and is predictive in deciding on timely endotracheal intubation.

Troubles de la conscience au service de réanimation polyvalente du Centre Hospitalier Universitaire Analakininina, Toamasina, Madagascar / Impaired consciousness in the intensive care unit at Analankininina Teaching Hospital of Toamasina, Madagascar

La survenue d'un coma ou de troubles de la conscience en réanimation est très fréquemment observée et leur présence est associée à un pronostic sévère. Nos objectifs étaient de décrire le profil épidémio-clinique des patients admis pour coma et trouble de la conscience ainsi que les principales étiologies de ces manifestations cliniques. Méthodes : Il s'agissait d'une étude prospective, descriptive, longitudinale de Juin à Novembre 2019. Le cadre de notre étude était le service de réanimation polyvalente du centre hospitalier universitaire (CHU) Analakininina Toamasina. Résultats : Nous avions recensé 77 patients dont 37 femmes et 40 hommes (sex ratio de 1,081). La moyenne d'âge était de 39 +/-17 ans. La majorité des patients soit 67% présentait un trouble de la conscience, le reste (31%) était comateux. La principale étiologie des troubles rencontrés était l'AVC (53%) dont 61% était hémorragiques, 17% ischémiques, et 22% non étiquetés. Plus de la moitié des patients avaient évolué vers le décès (61%). Conclusion : Pour l'amélioration du pronostic des patients, il serait nécessaire de connaitre les étiologies fréquentes afin d'adapter la prise en charge

Les facteurs associés aux morbi-mortalités maternelles de l'éclampsie à la maternité de Befelatanana / Factors associated with maternal eclampsia morbidity and mortality at the maternity hospital of Befelatanana

L'éclampsie est une complication neurologique majeure de la pré-éclampsie sévère, responsable d'une lourde morbidité et mortalité maternelle. L'objectif de cette étude était de déterminer les facteurs associés aux morbimortalités maternelles de l'éclampsie. Patients et Méthodes : Il s'agissait d'une étude rétrospective, transversale, descriptive et analytique ; sur une période de 36 mois, allant de Janvier 2019 à Décembre 2021, réalisée à la maternité de Befelatanana. Les paramètres cliniques et obstétricales, la prise en charge, les complications et l'évolution maternelle ont été les paramètres étudiés. Résultats : Sur 21 514 accouchements, 461 cas (2,14%) d'éclampsie ont été recensé dont 288 cas inclus dans l'étude. L'âge moyen était de 23,29±6 ans ; l'âge gestationnel était > 37 semaine d'aménorrhée dans 60,10% (n= 173) des cas et la grossesse étaient mal suivies dans 49,70% (n=143) des cas. Les complications maternelles dominées par : la détresse respiratoire aigüe sur pneumopathie d'inhalation; le coma prolongé ; une hémorragie intracérébrale et l'association à d'autres complications tel que : un HELLP syndrome, un hématome rétroplacentaire et une insuffisance rénale oligo-anurique aigue. Les facteurs associés aux décès étaient : l'existence de trouble de la conscience postcritique (p=0,026 ; OR=3,2 [1,09-9,37]), l'existence de coma prolongé ≥24h (p=10-8 ; OR=34 [11,47-100,71]), l'existence d'une insuffisance rénale aigue (p=10-4 ; OR=4,42 [2,08-9,4]) et l'association à un HELLP syndrome (p=10-8 ; OR=29,16 [12,08-70,41]). Conclusion : La morbi-mortalité de l'éclampsie reste encore très élevé à Madagascar ; une éducation de la population Malagasy doit être renforcer sur le suivi médical rapproché de la grossesse
