Cognitive dysfunction caused by blast traumatic brain injury (bTBI) is a serious neurological disease with high incidence, serious condition and poor prognosis. bTBI can lead to a series of symptoms such as short-term memory loss, inattention or multi-tasking difficulties. In severe cases, bTBI can develop into Alzheimer′s disease, which has a great impact on patients′ normal work and life. At present, researches on cognitive dysfunction caused by bTBI mainly involve model construction, pathogenesis, pathophysiological changes, diagnosis and treatment, etc., and the molecular mechanism of its occurrence remains to be further studied. Under normal physiological conditions, the release of excitatory and inhibitory neurotransmitters, the release and uptake of Ca 2+, oxidation and antioxidant systems, and the promotion and inhibition of apoptosis are in a dynamic balance. bTBI disturbs the balance, which will lead to the damage of nerve cells at the molecular level, thus resulting in the occurrence of cognitive dysfunction. To this end, the authors summarized the aspects of excitatory toxicity and Ca 2+homeostasis disorder, oxidative stress, inflammation and edema, apoptosis, etc., and reviewed the research progress on the molecular mechanism of cognitive dysfunction caused by bTBI, so as to provide a reference for the treatment and rehabilitation of cognitive dysfunction in patients with bTBI.

Objective:To investigate the risk factors and their warning effectiveness for postoperative intestinal barrier dysfunction (IBD) in patients with severe traumatic brain injury (sTBI).Methods:A retrospective cohort study was conducted to analyze the clinical data of 101 patients with sTBI admitted to Wuxi Branch of Zhongda Hospital Affiliated to Southeast University from May 2020 to February 2023, including 63 males and 38 females, aged 21-81 years [(53.4±14.2)years]. All the patients underwent emergency surgery. The patients were divided into IBD group ( n=67) and non-IBD group ( n=34) according to whether or not they had IBD after surgery. The gender, age, basic diseases (hypertension and diabetes), types of intracranial hematoma (subdural, epidural, and intracerebral hematoma), preoperative Glasgow Coma Scale (GCS), cerebral hernia, intraoperative initial intracranial pressure (iICP), operation time, removal of bone flap, treatment time in ICU, initiation time of enteral nutrition, and use of broad-spectrum antibiotics were recorded in the two groups. Univariate and multivariate binary Logistic regression analyses were conducted to assess the correlations between above-mentioned indicators and incidence of postoperative IBD in sTBI patients and determine the independent risk factors for sTBI. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the warning effectiveness of each risk factor for IBD. Results:The results of the univariate analysis showed that preoperative GCS, cerebral hernia, intraoperative iICP, removal of bone flap, treatment time in ICU, initiation time of enteral nutrition, and use of broad-spectrum antibiotics were significantly correlated with the incidence of IBD in sTBI patients ( P<0.05 or 0.01), while there were no correlations of IBD with gender, age, basic diseases, types of intracranial hematoma and operation time ( P>0.05). The results of the multivariate binary Logistic regression analysis showed that preoperative GCS≤5 points ( OR=2.49, 95% CI 1.17, 5.32, P<0.05), intraoperative iICP>23 mmHg (1 mmHg=0.133 kPa)( OR=1.20, 95% CI 1.03, 1.39, P<0.05), and initiation time of enteral nutrition>24 hours ( OR=10.03, 95% CI 1.26, 80.21, P<0.05) were highly correlated with postoperative IBD in sTBI patients. The results of the ROC curve analysis showed that intraoperative iICP had the highest warning value (AUC=0.91, 95% CI 0.85, 0.96), followed by preoperative GCS (AUC=0.88, 95% CI 0.82, 0.95), and initiation time of enteral nutrition had the lowest warning value (AUC=0.78, 95% CI 0.69, 0.87). Conclusions:Preoperative GCS≤5 points, intraoperative iICP>23 mmHg, and initiation time of enteral nutrition>24 hours are independent risk factors for postoperative IBD in sTBI patients. The warning value of intraoperative iICP ranks the highest for postoperative IBD in sTBI patients, followed by preoperative GCS, with initiation time of enteral nutrition having the lowest warning value.
RÉSUMÉ
Consciousness disorders following traumatic brain injury (TBI) are alterations in consciousness due to damage to the brain parenchyma and/or brain vessels. As the number of TBI patients continues to increase, so does the number of patients with consciousness disorders following TBI. The patients′ quality of life was seriously affected due to a long course of illness and loss of most of independence. However, at present, the mechanisms of consciousness disorders in TBI are still unknown. The assessment of conscious state in patients with consciousness disorders following TBI mainly depends on scales, resulting in a high rate of misdiagnosis. Common interventions, including pharmacological interventions such as amantadine and zolpidem, as well as non-pharmacological interventions such as neuromodulation and sensory stimulation programs, fail to achieve extensive efficacy. Therefore, there is an urgent need for more accurate assessment indicators as well as effective therapeutic interventions. Various neurophysiological activities sustained by sleep are crucial for consciousness. Sleep regularity is likely to reflect the conscious state of patients with consciousness disorders following TBI. Sleep regularity is generally reflected through sleep architecture, including circadian rhythms and various sleep characteristics. Therefore, the authors reviewed the research progress in the application of sleep architecture in the assessment and recovery of conscious state in patients with consciousness disorders following TBI, so as to provide reference for its clinical application.

Objective:To explore the risk factors, clinical features and prognosis of traumatic cerebral infarction in patients with craniocerebral trauma.Methods:The clinical data and follow-up data of 48 patients with craniocerebral trauma and traumatic cerebral infarction (observation group) and 132 patients with craniocerebral trauma without traumatic cerebral infarction (control group) admitted to the Sanya Central Hospital from January 2021 to January 2023 were retrospectively reviewed. Statistically significant risk factors were screened out by univariate analysis and Logistic regression analysis.Results:The results of univariate analysis showed that there were no significant differences in age, sex, skull fracture, traumatic subarachnoid hemorrhage and multiple injuries between the two groups ( P>0.05). There were statistical differences in midline displacement, herniation, diffuse brain swelling, decompression of the deboned flap, hemorrhagic shock, and admission Rotterdam CT score >3( P<0.05). The results of multivariate Logistic regression analysis showed that cerebral herniation, diffuse brain swelling and hemorrhagic shock were risk factors for traumatic cerebral infarction ( P<0.05). The higher the Rotterdam CT score, the higher the incidence of traumatic cerebral infarction. In the observation group, 11 cases had good prognosis and 37 cases had poor prognosis, with an average Glasgow Prognostic Scale (GOS) of (2.45 ± 1.22) points. In the control group, 74 cases had good prognosis and 48 cases had poor prognosis, with an average GOS of (3.69 ± 1.10) points. The difference in prognosis between the two groups was statistically significant ( P<0.05). Conclusions:Cerebral herniation, diffuse cerebral swelling and hemorrhagic shock are risk factors for traumatic cerebral infarction in patients with craniocerebral trauma, and the prognosis of patients complicated by traumatic cerebral infarction is worse.

Objective:To investigate the value of ultrasonic measurement of the ratio of optic nerve sheath diameter (ONSD) to eyeball transverse diameter(ETD) in the diagnosis and prognosis of intracranial hypertension in patients with craniocerebral trauma.Methods:A total of 120 patients with craniocerebral trauma treated in the Xingtai General Hospital of North China Medical and Health Group from December 2021 to January 2023 were perspectively selected, and they were divided into normal intracranial pressure group (73 cases) and intracranial hypertension group (47 cases) according to the results of intracranial pressure measurements, and the intracranial hypertension group was divided into good prognosis group (20 cases) and poor prognosis group (27 cases) according to the follow-up prognosis. The efficacy of ONSD, ETD and ONSD/ETD in intracranial hypertension diagnosis and prognosis assessment were analyzed by receiver operating characteristic (ROC) curve. Kaplan-Meier method was used to evaluate the 6-month risk of adverse prognosis of patients, and the comparison was made by Log-rank test.Results:The levels of intracranial pressure, ONSD, ONSD/ETD in the normal intracranial pressure group were lower than those in the intracranial hypertension group: (130.73 ± 23.63) mmH 2O (1 mmH 2O = 0.009 8 kPa) vs. (270.11 ± 35.78) mmH 2O, (5.47 ± 0.29) mm vs. (5.78 ± 0.44) mm, 0.246 ± 0.018 vs. 0.263 ± 0.018, there were statistical differences ( P<0.05). The scores of Glasgow Coma Scale (GCS), intracranial pressure, ONSD, ONSD/ETD in the good prognosis group were lower than those in the poor prognosis group: (5.50 ± 1.24) scores vs. (6.41 ± 1.34) scores, (256.15 ± 30.23) mmH 2O vs. (280.44 ± 36.56) mmH 2O, (5.62 ± 0.40) mm vs. (5.90 ± 0.44) mm, 0.254 ± 0.014 vs. 0.270 ± 0.017, there were statistical differences ( P<0.05). ROC curve analysis results showed that the area under the curve (AUC) of ONSD and ONSD/ETD for diagnosing intracranial hypertension in patients with craniocerebral trauma were 0.718 and 0.765, respectively, and the critical values were 5.87 mm and 0.263, respectively. The AUC of ONSD and ONSD/ETD predicting prognosis of intracranial hypertension patients was 0.677 and 0.763, respectively, and the critical values were 5.90 mm and 0.267, respectively. Grouped by the threshold of ONSD/ETD for the prognosis of intracranial hypertension (0.267), the incidence of adverse prognosis in ONSD/ETD > 0.267 group was higher than that in the ONSD/ETD≤0.267 group, there was statistical difference ( P<0.05). Conclusions:ONSD/ETD can be used as an index for diagnosis and prognosis of intracranial hypertension.

Não há dúvidas sobre os prejuízos na vida humana, extensivos à família e sociedade como um todo, abrangendo todos os aspectos funcionais das pessoas envolvidas, além do indivíduo, originados dos traumatismos cranioencefálico, agudos e crônicos, externos ou internos: acidentes, atropelamentos, quedas, crimes, acidente vascular cerebral, doenças com neurodegeneração progressiva, resultando em estados demenciais. Ao longo de meio século, houve a introdução contínua de medicamentos, com resultados usualmente contraditórios e frustrantes, exigindo novas tentativas com outras classes farmacológicas. No todo, a limitação se faz sentir na impossibilidade de reversão ou mesmo de mera estabilização dos danos neurológicos, e inocuidade em termos de estimulação da neuroplasticidade. Uma exceção parece ser uma nova abordagem: a estimulação cerebral profunda por pulsos sonoros de baixa frequência (Transcranial Pulse Stimulation, ou TPS). Ainda pouco conhecida, a não ser em alguns centros de tratamento, tem se mostrado ser um acréscimo válido, por complementar os programas multidisciplinares de reabilitação
There is no doubt about the damage to human life, also extended to family and society as a whole, regarding all the functional aspects of those involved, not only the patient itself, which originates from traumatic brain injury, acute or chronic, for external or internal reasons, such as accidents, run overs, falls, crimes, stroke, progressive neurodegenerative diseases that result in dementia states. Over half a century, drugs have been continuously introduced, however their results have constantly been contradictory and frustrating, requiring new attempts with other pharmacological classes. Overall, the limitation is felt in the impossibility of reversing or even merely stabilizing the neurological damage and inefficacy regarding neuroplasticity stimulation. One exception seems to be a new approach, the non-invasive brain stimulation by low-frequency sound pulses (Transcranial Pulse Stimulation, or TPS). Except for some treatment centers, TPS is still unknown, however it has shown to be a valid adjunct in multidisciplinary rehabilitation programs

Objective:To investigate the value of chain management of perioperative pressure injury in patients undergoing supine craniocerebral injury, so as to provide reference for the prevention of pressure injury and the application of chain management.Methods:In this retrospective study, a total of 116 patients with craniocerebral injury who underwent supine surgery in Shanxi Cardiovascular Hospital from December 2019 to December 2020 were included in the control group, using traditional perioperative pressure injury management protocol. And 124 patients admitted from January 2021 to December 2021 were included in the observation group, and were managed by the pressure injury chain management scheme. The risk assessment/judgment rate of pressure ulcers, the risk assessment/judgment accuracy rate of pressure ulcers, the implementation rate of intervention measures, the qualified rate of intervention records and the reported rate of high-risk patients with pressure ulcers in the two groups were analyzed. The occurrence of stress injury and medical expenses of the two groups of patients were investigated.Results:The risk assessment/judgment rate of pressure ulcers, the risk assessment/judgment accuracy rate of pressure ulcers, the implementation rate of intervention measures, the qualified rate of intervention records and the reported rate of high-risk patients with pressure ulcers were 100.00%(124/124), 96.77%(120/124), 92.74%(115/124), 93.55%(116/124), 100.00%(29/29) in the observation group, which were 77.59%(90/116), 72.41%(84/116), 68.97%(80/116), 68.97%(80/116), 83.33%(30/36) in the control group, the difference was statistically significant ( χ2 values were 22.24-31.17, all P<0.05). The overall incidence of stress injury in the observation group and the control group was 15.52%(18/116) and 3.23%(4/124), respectively, and the difference between the two groups was statistically significant ( χ2=10.88, P<0.05). There was no significant difference in the total hospitalization cost between the two groups ( P>0.05). The cost of stress-related consumables was (144.94 ± 47.28) yuan in the observation group and (194.21 ± 55.76) yuan in the control group, and the difference was statistically significant ( t=7.40, P<0.05). Conclusions:Perioperative stress injury chain management can reduce the incidence of pressure injury in patients with craniocerebral injury, improve service quality, and reduce medical costs, with good clinical application value.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

Objective:To observe the effect of neuroendoscope-assisted drainage with lumbar cistern and large bone flap decompression in the treatment of craniocerebral injury complicated with temporal uncinate herniation.Methods:A total of 80 patients with craniocerebral trauma and temporal uncinate herniation hospitalized in Lanling County People′s Hospital from January 2017 to October 2020 were retrospectively included and divided into the observation group and the control group according to the surgical methods, with 40 patients in each group. Surgical procedures were performed by the same group of experienced neurosurgeons. The observation group was treated with neuroendoscope-assisted drainage with lumbar cistern and large bone flap decompression, while the control group was treated with large bone flap decompression only. Cephalic CT was reexamined before and 48 h after the surgery to compare the appearance rates of cisterna ambiens and suprasellar cistern. Intracranial pressure (ICP) was monitored at 3, 5 and 7 d after the surgery, and the scores of Glasgow coma scale(GCS) was recorded. Drainage time, postoperative cerebral edema and cerebral infarction complications were recorded and compared between the two groups. Six months after the surgery, the prognosis was assessed by the Glasgow prognostic scale (GPS).Results:The occurrence rates of cisterna ambiens and suprasellarcistern in the observation group were higher than those in the control group: 67.50%(27/40) vs. 45.00%(18/40), 65.00%(26/40) vs. 42.50%(17/40), χ2 = 4.11, 4.07, P<0.05. The ICP value in the observation group at 3, 5 and 7 d after the surgery were significantly lower than those in the control group, and the scores of GCS in the observation group were significantly higher than those in the control group, there were statistical differences( P<0.05). There was no statistically significant difference in drainage time between the two groups ( P>0.05). The incidence of postoperative cerebral edema in the observation group was lower than that in the control group:7.50%(3/40) vs. 25.00%(10/40), χ2 = 4.50, P<0.05. The incidence of postoperative cerebral infarction in the observation group was lower than that in the control group, and the volume of cerebral infarction was smaller than that in the control group: 5.00%(2/40) vs. 22.50%(9/40), (6.68 ± 1.75) cm 3 vs. (8.20 ± 2.15) cm 3, there were statistical differences ( P<0.05). The incidence of postoperative complications in the observation group was lower than that in the control group: 7.50%(7/40) vs. 40.00%(16/40), χ2 = 4.94, P<0.05. Six months after the surgery, the rate of good prognosis in the observation group was higher than that in the control group: 62.50%(25/40) vs. 35.00%(14/40), χ2 = 6.05, P<0.05. Conclusions:Neuroendoscope-assisted drainage with lumbar cistern and large bone flap decompression in the treatment of craniocerebral trauma and temporal uncinate herniation has good efficacy and safety.

Objective:To explore the application value of ventricular intracranial pressure monitoring (V-ICPM) in the treatment of unilateral temporal lobe cerebral contusion.Methods:A retrospective cohort study was conducted to analyze the clinical data of 295 patients with unilateral temporal lobe cerebral contusion admitted to 904th Hospital of PLA Joint Support Force from January 2014 to August 2021, including 172 males and 123 females; aged 14-78 years [(46.3±14.7)years]. V-ICPM was used in 136 patients (V-ICPM group), who received surgical or non-surgical treatment according to the monitoring, while not in 159 patients (non-V-ICPM group), who received routine surgery or non-surgical treatment. The two groups were compared in terms of the rates of intracranial hematoma clearance by craniotomy, decompressive craniectomy (DC) and dehydration and osmotic therapy during hospitalization, use time of 20% mass fraction of mannitol and 30 g/L hypertonic salt, displacement rate of brain midline structure of head CT≥10 mm after discharge, rate of intracranial infection, hydrocephalus and epilepsy, and Glasgow Outcome Scale (GOS) at 6 months after discharge.Results:All patients were followed up for 6-12 months [(8.9±2.1)months]. During hospitalization, the rate of intracranial hematoma clearance by craniotomy and the rate of DC in V-ICPM group were 35.3% (48/136) and 8.1% (11/136), lower than 47.2% (75/159) and 22.0% (35/159) in non-V-ICPM group ( P<0.05 or 0.01). There was no significant difference between the two groups in the rate of dehydration and osmotic therapy or the use time of mannitol (all P>0.05). The use time of hypertonic salt in V-ICPM group was (7.2±2.5)days, more than (4.1±1.8)days in non-V-ICPM group ( P<0.05). After discharge, the displacement rate of brain midline structure of head CT in V-ICPM group was 29.4% (40/136), lower than 42.8% (68/159) in non-V-ICPM group ( P<0.05). There was no significant difference between the two groups in the rate of intracranial infection, hydrocephalus and epilepsy (all P>0.05). Six months after discharge, the good rate of GOS in V-ICPM group was 91.2% (124/136), significantly better than 81.8% (130/159) in non-V-ICPM group ( P<0.05). Conclusion:For unilateral temporal lobe cerebral contusion, V-ICPM is associated with reduced rate of craniotomy exploration and DC, decreased incidence of complications and improved prognosis of the patients in spite of longer use time of hypertonic salt.

Posttraumatic acute diffuse brain swelling (PADBS) is a relatively common severe traumatic brain injury (TBI). Since it can lead to acute intracranial hypertension in a short time, the illness can be acute and critical, with a high disability and fatality rate. The pathogenesis of PADBS is still unclear, with the current theory consisting of acute cerebral vasodilation, cerebral edema and intracranial venous circulation disorder. For PADBS, there is still a lack of unified diagnostic criteria, and the indications and timing of decompression craniectomy remain controversial. The authors review the research progress in the pathogenesis, diagnosis and treatment of PADBS, hoping to provide some new ideas for its treatment.
RÉSUMÉ
Traumatic brain injury (TBI) is much more complex considering the unique pathophysiological changes under high-altitude hypoxic environment. Moreover, because of limited source of medical transportation and facilities at high altitude, TBI patients often lack urgent and standard treatment and have to be transported to the district medical center at high altitude or even the neurotrauma center at plain region as soon as possible. The transportation has high risk and takes serious effect on lives and prognosis of the TBI patients. Up to date, the evacuation and support process for TBI patients in the western plateau region of China has been improved through years of practice, but there are still deficiencies compared to the Critical Care Air Transport Team (CCATT). The authors sought to discuss certain issues related to medical evacuation and support after TBI at high altitude from aspects of early damage control operation and timely safety medical transportation, aiming to improve the survival rate, neurological outcomes and life quality for these patients.

Craniocerebral war injury, mainly caused by weaponry equipment and wartime conditions during warfare, are characterized by high difficulty in treatment and evacuation as well as high mortality rate. The field surgical treatment of craniocerebral war injury is not only related to injury characteristics, but also to factors such as war scale, combat style, combat area and weapon power. In recent years, there have been few comprehensive reports on the characteristics and field surgical treatment of craniocerebral war injury in China. Therefore, the authors reviewed the research progress in the characteristics and field surgical treatment of craniocerebral war injuries in foreign armies since 2001, with the aim to provide a reference for relevant basic researches and war injury treatment in China.

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.

Objective:To explore the effect of different blood sodium levels on the condition and prognosis of patients with severe craniocerebral injury.Methods:A retrospective cohort study was conducted on 150 cases of severe craniocerebral injury admitted to Zhangye People′s Hospital Affiliated to Hexi University from January 2020 to October 2022. According to the five blood sodium values measured on the first day after admission and during the peak period of brain edema (2-4 days after injury) and 7 days after injury, 102 cases of blood sodium metabolic disorder, 43 cases of low sodium group: average blood sodium value<135 mmol/L, 59 cases of high sodium group: average blood sodium value>145 mmol/L. The characteristics of sodium ion metabolism imbalance and the relationship between serum sodium level and Glasgow coma score (GCS), Glasgow prognosis score (GOS) and APACHE Ⅱ score at 2 weeks after injury were analyzed. Measurement data with normal distribution were represented as mean±standard deviation ( ± s), and comparison between groups was conducted using the t-test. count data were expressed as cases or percentages(%), and comparison between groups was conducted using the Chi-square test. Results:The imbalance rate of sodium metabolism in the acute phase after injury was 68.00%(102/150), including 57.84%(59/102) of hypernatremia and 42.16%(43/102) of hyponatremia. The imbalance rate of sodium metabolism at 7 days after injury was significantly higher than that immediately after injury. Hypernatremia occurred earlier than hyponatremia and lasted longer than hyponatremia ( P<0.05). There was no correlation between the low sodium group and the scores of GCS ( R=0.523), GOS ( R=0.367), APACHE Ⅱ ( R=-0.453) ( P>0.05), but the scores of GCS ( R=-0.448) and GOS ( R=-0.486) were negatively correlated with the blood sodium level of the high sodium group ( P<0.05), and the high sodium group was positively correlated with the scores of APACHE Ⅱ ( R=0.477, P<0.05). Conclusions:Patients with severe craniocerebral injury are often accompanied by blood sodium disorder. Hyponatremia can be corrected in a short time and has no effect on the patient′s condition and prognosis. However, hypernatremia seriously affects the recovery of consciousness, prognosis and quality of life of the injured.

Objective:To analyze the injury factors and prognosis of children with traumatic brain injury (TBI), and to explore the risk factors affecting its severity, so as to provide evidence for the prevention and intervention of TBI in children.Methods:A total of 6 040 children with TBI who were admitted to the Department of Neurosurgery of Children's Hospital of Soochow University from January 1, 2011 to December 31, 2020 were selected. The injury factors and prognosis were retrospectively analyzed. Univariate and multivariate Logistic regression analysis was used to analyze the factors affecting the severity of TBI in children.Results:Of the 6 040 children, 3 681 were males and 2 359 were females. The patients aged 1 to 3 years accounted for the highest proportion (34.0%, 2 056/6 040), and most of them were mild injuries (93.2%, 5 631/6 040). The main injury sites of children with TBI were road (35.9%, 2 167/6 040) and home (31.1%, 1 881/6 040), and the main causes of injury were falling from height (34.9%, 2 107/6 040) and falling (34.5%, 2 085/6 040). Children aged 1 to 3 years were most likely to be injured at home(41.9%, 861/2 056), mainly due to falling from height, while children aged 4 to 6 years were most likely to be injured on the road(43.8%, 828/1 891), mainly due to falling. Logistic regression analysis showed that children's residence, the presence of multiple injuries and the location of brain injury were independent influencing factors for the severity of TBI in children ( χ2=6.58, 138.15, 4.25, all P <0.05). Conclusions:TBI in children aged 1 to 3 years mainly occurred at home, and in children aged 4 to 6 years mainly occurred on the road. Falling from height and falling are the main causes of TBI in children. The society, schools and families should take targeted prevention education and intervention measures according to different age groups. Children who live in rural areas, have multiple injuries, and have multiple brain injury sites are more severely injured. In the process of treating children with TBI, the severity can be quickly predicted based on this, and the treatment efficiency of children with TBI can be improved.
