Nutritional Status of Patients with Chronic Critical Illness

Material and methods. We examined 23 patients with chronic critical illness who were in a minimally conscious state (MCS) with 10.9±2.5 scores on the FOUR (Full Outline of Unresponsiveness) Score Coma Scale. Indicators of carbohydrate, lipid, protein and energy exchange metabolism were evaluated using specimens sampled in the morning hours. Nutritional support was provided by isocaloric isonitrogenic mixtures.Results. Blood biochemistry showed decreases in total protein and albumin levels in 86.9% and 91.3% of patients, respectively. The tests also revealed decreased concentrations of several amino acids, including essential amino acids: histidine (38.3±13.07 µmol/l), methionine (12.68±3.81 µmol/l), threonine (61.6 [58.5;87.7] µmol/l), tryptophan (33.06±15.95 µmol/l), and non-essential amino acids: arginine (40.50 [22.2; 46.9] µmol/l), glutamic acid (124.5±39.29 µmol/l), tyrosine (37.97±10.12 µmol/l). Some correlations between the concentrations of individual amino acids and other indicators were revealed, such as histidine and CRP (r=–0.68, P=0.043), tryptophan and CRP (r=–0.86, P=0.002), histidine and leukocyte count (r=–0.76, P=0.015), methionine and lysine (r=0.88, P=0.008), methionine and patient's weight (r=–0.68, P=0.042). A relationship between threonine concentration and the level of consciousness on the FOUR scale (r=–0.73, P=0.037) was also found. All patients demonstrated significant alterations of carbohydrate and lipid metabolism.Conclusion. Alteration of adequate protein metabolism seems to be the most affected constituent in the nutritional status of patients with chronic critical illness. It is manifested by a decrease in the concentration of total protein and a number of essential and non-essential amino acids, which implies the importance of highprotein nutritional support and correction of the amino acid profile.

Analysis of the Therapeutic Effect and Prognostic Factors of 126 Patients With Hypertensive Cerebral Hemorrhage Treated by Soft-Channel Minimally Invasive Puncture and Drainage.

BackgroundSurgery is the main method for the clinical treatment of hypertensive cerebral hemorrhage. Traditional craniotomy faces the disadvantages of the long operation time, easy to cause secondary injury to patients during the operation, and prone to infection after the operation, which is not conducive to the rehabilitation of patients. At present, it is urgent to find a surgical scheme, which can clear hematoma in time, protect brain tissue, and effectively reduce surgical trauma in the clinic.Materials and MethodsThe case database of our hospital was consulted, and the clinical data of patients with hypertensive intracerebral hemorrhage (HICH) treated with soft channel minimally invasive puncture and drainage from February 2018 to October 2021 were retrospectively analyzed. Patients were evaluated for efficacy, and the changes in serum C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), homocysteine (Hcy), endothelin (ET), and vasopressin (AVP) levels before surgery, 3 days after surgery, and 7 days after surgery were analyzed. Clinical data were collected and Logistic regression was used to analyze the prognostic factors.ResultsFinally, according to the inclusion and exclusion criteria, 126 patients were selected as the research object. Among them, there were 24 cases (19.05%) of recovery, 47 cases (37.30%) of markedly effective, 34 cases (26.98%) of effective, 11 cases (8.73%) of ineffective, and 10 cases (7.94%) of death. The total effective rate was 83.33%. The hematoma was basically removed in 116 cases (92.06%). The average evacuation time of hematoma was (7.82 ± 1.63) days. Post-operative intracranial infection occurred in 2 cases (1.59%) and post-operative rebleeding occurred in 5 cases (3.97%). The average hospital stay was (34.16 ± 16.59) days. Serum CRP, TNF-α, IL-6, Hcy, ET, and AVP levels of all patients on the third and seventh days after surgery were lower than those before surgery, and those on the seventh day after surgery were lower than those on the third day after surgery (p < 0.05). The differences in pre-operative Glasgow Coma Scale (GCS) score, bleeding volume, ventricular rupture, complicated cerebral hernia, and attack time to surgery between the good prognosis group and the bad prognosis group were statistically significant (p < 0.05). Pre-operative GCS score, bleeding volume, ventricular rupture, complicated cerebral hernia, and onset time to surgery were all independent factors that affect the prognosis of patients (p < 0.05).ConclusionSoft-channel minimally invasive puncture and drainage treatment of HICH has a significant effect, which is conducive to the complete removal of hematoma, reducing hospitalization time, while adjusting the balance and stability of various cytokines, and improving patient prognosis. Pre-operative GCS score, bleeding volume, rupture into the ventricle, complicated cerebral hernia, and time from onset to operation are all independent factors that affect the prognosis of patients.

Experience of Using a New Brain Surgery Head Frame and Location Sticker for Treating Spontaneous Intracranial Hematoma.

ObjectivesVarious stereotactic aspirations have been accepted; however, no standard stereotactic aspiration has been established for the treatment of spontaneous intracerebral hemorrhage (ICH). The authors explored an easy, fast, and effective procedure by using a new brain surgery head frame and location sticker for the removal of spontaneous hematoma.Patients and MethodsA retrospective database review was performed from January 2018 to March 2020 to identify patients with ICH who were treated with puncture and drainage for hematoma by using a new brain surgery head frame and location sticker for positioning and guidance.ResultsA total of 45 patients with spontaneous ICH were enrolled in our study. The mean (± SD) surgical time was 29.3 ± 4.1 min. The average hematoma evacuation rate was 72.2%. The mean (± SD) preoperative Glasgow Coma Scale (GCS) score was 9.58 ± 2.92; the mean GCS score increased to 11.55 ± 2.59 (p = 0.006) and 12.86 ± 2.04 (p < 0.001) at 1 week after surgery and at the time of discharge, respectively. The mean (± SD) preoperative muscle force score was 1.25 ± 1.51; the mean muscle force score had improved to 2.20 ± 1.64 (p = 0.009) and 2.88 ± 1.64 (p < 0.001) at 1 week after the operation and the time of discharge, respectively. Out of these, one patient experienced postoperative rebleeding, however, no further hematoma expansion was found after the second aspiration and thrombolysis.ConclusionUsing this brain surgery, head frame and location sticker combined with urokinase infusion appears simple, safe, and effective for the removal of hematoma for patients with spontaneous ICH. However, randomized controlled trials are necessary to provide more concrete evidence-based results.

Prognostic Nomogram for Predicting Lower Extremity Deep Venous Thrombosis in Neurointensive Care Unit Patients: A Prospective Observational Study.

BackgroundDeep venous thrombosis (DVT) of the lower extremities is one of the common complications for neurointensive care unit patients, which leads to increased morbidity and mortality. The purpose of our study was to explore risk factors and develop a prognostic nomogram for lower extremity DVT in neurointensive care unit patients.MethodsWe prospectively collected and analyzed the clinical data of 420 neurointensive care unit patients who received treatment in our institution between January 2018 and September 2019. Stepwise logistic regression was used to select predictors. R software was used to develop the prognostic nomogram. The performance of the nomogram was validated using a validation cohort of patients with data collected between October 2019 and March 2020.ResultsAmong 420 patients, 153 (36.4%) had lower extremity DVT and five (1.2%) had both DVT and pulmonary embolism (PE) in our study. Logistic regression analysis indicated that age [odds ratio (OR): 1.050; 95% confidence interval (CI): 1.029–1.071; P < 0.001], Glasgow Coma Scale (GCS) score (OR: 0.889; 95% CI: 0.825–0.959; P = 0.002), D-dimer level (OR: 1.040; 95% CI: 1.008–1.074; P = 0.014), muscle strength (OR: 2.424; 95% CI: 1.346–4.366; P = 0.003), and infection (OR: 1.778; 95% CI: 1.034–3.055; P = 0.037) were independent predictors for lower extremity DVT. These predictors were selected to be included in the nomogram model. The area under the curve values in the primary cohort and validation cohort were 0.817 (95% CI: 0.776–0.858) and 0.778 (95% CI: 0.688–0.868), respectively, and respective Brier scores were 0.167 and 0.183.ConclusionAge, GCS score, D-dimer level, muscle strength, and infection are independent predictors for lower extremity DVT. The nomogram is a reliable and convenient model to predict the development of lower extremity DVT in neurointensive care unit patients.

HIV Infection Is an Independent Predictor of Mortality Among Adults with Reduced Level of Consciousness in Uganda.

ABSTRACT.The clinical epidemiology of adults admitted with reduced level of consciousness (LOC) in sub-Saharan Africa (SSA) and the impact of HIV infection on the risk of mortality in this population is unknown. We secondarily analyzed data from a cohort study that enrolled 359 consecutive adults with reduced LOC presenting to Mbarara Regional Hospital in Uganda with the aim of comparing the prognostic utility of the Full Outline of Unresponsiveness (FOUR) score to the Glasgow Coma Scale (GCS) Score. For this analysis, we included 336 individuals with known HIV serostatus, obtaining clinical, laboratory, and follow-up data. We recorded investigations and treatments deemed critical by clinicians for patient care but were unavailable. We computed mortality rates and used logistic regression to determine predictors of 30-day mortality. The median GCS was 10. Persons living with HIV infection (PLWH) accounted for 97 of 336 (29%) of the cohort. The 30-day mortality rate in the total cohort was 148 of 329 (45%), and this was significantly higher in PLWH (57% versus 40%, adjusted odds ratio [aOR] 2.39: 95% confidence interval [CI]: 1.31–4.35, P = 0.0046). Other predictors of mortality were presence of any unmet clinical need (aOR 1.72; 95% CIL 1.04–2.84, P = 0.0346), anemia (aOR 1.68; 95% CI: 1.01–2.81, P = 0.047), and admission FOUR score < 12 [aOR 4.26; 95% CI: 2.36–7.7, P < 0.0001). Presentation with reduced LOC in Uganda is associated with high mortality rates, with worse outcomes in PLWH. Improvement of existing acute care services is likely to improve outcomes.

Alcohol is not associated with increased mortality in adolescent traumatic brain injury patients

PurposeCompared to adults, there is a paucity of data regarding the association of a positive alcohol screen (PAS) and outcomes in adolescent patients with traumatic brain injury (TBI). We hypothesize adolescent TBI patients with a PAS on admission to have increased mortality compared to patients with a negative alcohol screen.MethodsThe 2017 Trauma Quality Improvement Program database was queried for patients aged 13–17 years presenting with a TBI and serum alcohol screen. Patients with missing information regarding midline shift on imaging and Glasgow Coma Scale (GCS) score were excluded. A multivariable logistic regression analysis for mortality was performed.ResultsFrom 2553 adolescent TBI patients with an alcohol screen, 220 (8.6%) had a PAS. Median injury severity scores and rates of penetrating trauma (all p > 0.05) were similar between alcohol positive and negative patients. Patients with a PAS had a similar mortality rate (13.2% vs. 12.1%, p = 0.64) compared to patients with a negative screen. Multivariate logistic regression controlling for risk factors associated with mortality revealed a PAS to confer a similar risk of mortality compared to alcohol negative patients (p = 0.40).ConclusionAdolescent TBI patients with a PAS had similar associated risk of mortality compared to patients with a negative alcohol screen.

Analysis of clinical distribution and drug resistance of klebsiella pneumoniae pulmonary infection in patients with hypertensive intra cerebral hemorrhage after minimally invasive surgery.

ABSTRACTObjectives:To investigate the clinical distribution and drug resistance of Klebsiella pneumoniae pulmonary infection in patients with hypertensive intracerebral hemorrhage after minimally invasive surgery.Methods:A total of 658 patients with hypertensive intracerebral hemorrhage who underwent minimally invasive surgery admitted to the intensive care unit (ICU) and the Department of Neurology of Affiliated Hospital of Hebei University from January 2015 to January 2020 were enrolled and divided into two groups: the observation group and the control group. Three hundred and thirty-three cases with postoperative pulmonary infection were included into the observation group, and 325 cases without postoperative pulmonary infection were divided into the control group. The intubation time, neurological deficiency score and Glasgow coma scale (GCS) of the two groups were analyzed and compared. Automatic microbial identification system was utilized to isolate bacteria from patients in the observation group, identify Klebsiella pneumoniae, and analyze Klebsiella pneumoniae infection, clinical department distribution, and age distribution. The Kirby-Bauer method was adopted to carry out the drug susceptibility test of Klebsiella pneumoniae infection.Results:The intubation time and neurological deficiency score of patients with hypertensive cerebral hemorrhage in the observation group were significantly higher than those in the control group (p<0.05), while the GCS score was significantly lower than that in the control group (p<0.05). A total of 403 strains of pathogenic bacteria were isolated from 325 patients in the observation group, of which 52 strains of Klebsiella pneumoniae were detected in 52 patients with postoperative pulmonary infection, accounting for 12.90%. The detection rates of Klebsiella pneumoniae in ICU and neurology department were 53.85% and 46.15%, respectively. Klebsiella pneumoniae had the highest detection rate (40.38%) in people aged 70 years and above. Moreover, fifty-two strains of Klebsiella pneumoniae showed low drug resistance rate (<20%) to cefoperazone/sulbactam, piperacillin/tazobactam, cefoxitin, imipenem, meropenem, amikacin, ciprofloxacin, and levofloxacin.Conclusion:For patients with hypertensive cerebral hemorrhage who have pulmonary infection after minimally invasive surgery, risk factors causing infection should be identified in time, their Klebsiella pneumoniae infection should be correctly monitored, and antibiotics should be taken rationally to effectively promote the elimination of brain edema in patients and protect the cranial nerve function of patients.

Does the time of the day affect multiple trauma care in hospitals? A retrospective analysis of data from the TraumaRegister DGU\xae

BackgroundOptimal multiple trauma care should be continuously provided during the day and night. Several studies have demonstrated worse outcomes and higher mortality in patients admitted at night. This study involved the analysis of a population of multiple trauma patients admitted at night and a comparison of various indicators of the quality of care at different admission times.MethodsData from 58,939 multiple trauma patients from 2007 to 2017 were analyzed retrospectively. All data were obtained from TraumaRegister DGU®. Patients were grouped by the time of their admission to the trauma center (6.00 am–11.59 am (morning), 12.00 pm–5.59 pm (afternoon), 6.00 pm–11.59 pm (evening), 0.00 am–5.59 am (night)). Incidences, patient demographics, injury patterns, trauma center levels and trauma care times and outcomes were evaluated.ResultsFewer patients were admitted during the night (6.00 pm–11.59 pm: 18.8% of the patients, 0.00–5.59 am: 4.6% of the patients) than during the day. Patients who arrived between 0.00 am–5.59 am were younger (49.4 ± 22.8 years) and had a higher injury severity score (ISS) (21.4 ± 11.5) and lower Glasgow Coma Scale (GCS) score (11.6 ± 4.4) than those admitted during the day (12.00 pm–05.59 pm; age: 55.3 ± 21.6 years, ISS: 20.6 ± 11.4, GCS: 12.6 ± 4.0). Time in the trauma department and time to an emergency operation were only marginally different. Time to imaging was slightly prolonged during the night (0.00 am–5.59 am: X-ray 16.2 ± 19.8 min; CT scan 24.3 ± 18.1 min versus 12.00 pm- 5.59 pm: X-ray 15.4 ± 19.7 min; CT scan 22.5 ± 17.8 min), but the delay did not affect the outcome. The outcome was also not affected by level of the trauma center. There was no relevant difference in the Revised Injury Severity Classification II (RISC II) score or mortality rate between patients admitted during the day and at night. There were no differences in RISC II scores or mortality rates according to time period. Admission at night was not a predictor of a higher mortality rate.ConclusionThe patient population and injury severity vary between the day and night with regard to age, injury pattern and trauma mechanism. Despite the differences in these factors, arrival at night did not have a negative effect on the outcome.

Xingnao Kaiqiao acupuncture on promoting wake-up of vegetative state after brain injury

To observe the clinical effect of Xingnao Kaiqiao acupuncture on promoting wake-up of vegetative state after brain injury on the basis of comprehensive rehabilitation training. A total of 100 patients with vegetative state after brain injury were randomly divided into an observation group (50 cases, 2 cases dropped off) and a control group (50 cases). Both groups were treated with routine clinical treatment. The patients in the control group were treated with rehabilitation and hyperbaric oxygen; on the basis of the control group treatment, the patients in the observation group were treated with Xingnao Kaiqiao acupuncture at Neiguan (PC 6), Shuigou (GV 26), Sanyinjiao (SP 6), Chize (LU 5), Weizhong (BL 40), Hegu (LI 4) and Taichong (LR 3). The acupuncture was given once a day, 5 days per week, for continuous 30 days. The Glasgow coma scale (GCS) and coma recovery scale-revised (CRS-R) scores were observed before treatment and 10, 20 and 30 days into treatment. The wake-up rate of the two groups was compared after treatment. On 10, 20 and 30 days into treatment, the GCS and CRS-R scores in the two groups were higher than those before treatment (P<0.01), and the scores in the observation group were higher than those in the control group (P<0.01). After treatment, the wake-up rate was 16.7% (8/48) in the observation group, which was higher than 12.0% (6/50) in the control group (P<0.01). On the basis of comprehensive rehabilitation and wake-up promotion therapy, the Xingnao Kaiqiao acupuncture could promote the recovery of consciousness level in patients with vegetative state after brain injury.

Patients With Suicidal Patterns in the Emergency Room: A Clinical and Social Reflection.

Background and objectiveEmergency physicians come across a myriad of medical afflictions resulting from suicide attempts. The Indian contribution to global suicide deaths is alarming; the social construct of India is unique, and so are the problems and challenges. This study aims to describe the social background, demographic parameters and correlate the clinical profile and outcomes of all patients presenting with an attempted or completed suicide.Materials and methodsThe present study is a hospital-based prospective observational study conducted by the Department of Emergency Medicine at RL Jalappa Hospital and Research Centre, a rural tertiary-care center in Karnataka, India, from June 2020 to February 2021. After stabilizing the patient, a detailed socio-demographic history was recorded. Details of the suicide attempt and findings of the clinical examination were noted.ResultsThe final study sample consisted of 89 patients who presented to the emergency room (ER). Fifty-three patients were female, and thirty-six were males; the average age of the sample was 28.4 ± 11 years. A higher proportion of men who completed pre-university education (p= 0.0005, c2= 11.98) or had a graduate degree (p= 0.009, c2= 6.71) attempted suicide. Amongst all women who attempted suicide, 73.6% (n=39) were married at the time of the event (p= 0.0006, c2= 11.79). Poisoning (n=59) was the most common method of attempting suicide. We also observed that it was primarily men who attempted suicide when under the influence of alcohol (p= 0.006, c2= 7.57). The most common reason for attempting suicide was familial disharmony, including domestic violence. A Glasgow Coma Scale (GCS) score of 9/15 and less at the time of presentation resulted in a mortality rate of 28.6%, whereas patients with a GCS score of 10 and above had a mortality rate of 6.1% (p= 0.04, c2= 4.14).DiscussionMarriage appears to be less protective for Indian women than Indian men. Poisoning was the most common method of attempted suicide in our study, followed by tablet overdose. The reason for the above could be ease of access to household poisons. Insecticides have been a preferred method in the Indian population over the years. Aluminum phosphide poisoning, a common constituent of rodenticides, is associated with a high mortality rate. However, in the West, firearm-related incidents have the highest mortality. Multiple correspondence analysis (MCA) of the National Crime Records Bureau (NCRB), India, data showed that adult males succumb majorly to romantic relations, unemployment, and failure in examinations. The use of alcohol was more in the illiterate and unskilled workers; however, high school educated persons and students used alcohol intentionally to facilitate suicide. Lower Glasgow Coma Scale values are associated with higher fatality; however, some studies found that Full Outline of Unresponsiveness (FOUR) and Acute Physiology and Chronic Health Evaluation Score (APACHE) II scores are better mortality indicators.ConclusionBesides the presentation and GCS score, cognizance of the lethality of different methods in attempting suicide provides clues in anticipating the patient's clinical course. The social patterns of suicide must be considered while designing awareness campaigns and focused outreach programs to decrease suicides. A strict policy must be made and enforced to limit the availability of household poisons.

Modern Phineas Gage: A Man with a Knife in the Brain

An accident with a tamping iron made Phineas Gage a historically famous brain-injury survivor. (1) Each year, approximately 1.6 million people sustain traumatic brain injury, leading to 52,000 deaths annually. (2) However, there is limited literature regarding traumatic brain penetration injury that could be found. A 42-year-old male with psychosis forcefully inserted a butter knife through nostril, traversed via sella turcica into posterior corpus callosum in a mental health facility. He was intubated in his local hospital and transferred over to a tertiary hospital for neurosurgical intervention. Radiological imaging showed impingement of knife against the posterior cerebral artery (PCA), multiple brain infarcts, intraventricular, and subarachnoid haemorrhage. The knife was removed after securing the PCA with the collaboration between neurosurgery and interventional radiology team. Sinus repair was immediately performed by the otorhinolaryngologists. External ventricular drain was inserted due to hydrocephalus secondary to brain haemorrhage. He eventually developed ventriculitis leading to sepsis and was treated with multiple antibiotics. The traumatic brain injury led to anterior hypopituitarism and diabetes insipidus which was treated using hormone therapy. He not only survived the fatal brain injury but also regained his Glasgow Coma Scale (GCS) score. This case demonstrates the potential of a multi-disciplinary and specialty approach to achieve outcomes a single specialty team could not. The outcome of a case which was deemed to be a non-survivable brain injury was made different due to the bold decision making, experience and innovative surgical strategy. Future research is needed to better understand and manage brain penetration injury.International Journal of Human and Health Sciences Supplementary Issue-2: 2021 Page: S27

Ketamine versus propofol for rapid sequence induction in trauma patients: a retrospective study

BackgroundRapid Sequence Induction (RSI) is used for emergency tracheal intubation to minimise the risk of pulmonary aspiration of stomach contents. Ketamine and propofol are two commonly used induction agents for RSI in trauma patients. Yet, no consensus exists on the optimal induction agent for RSI in the trauma population. The aim of this study was to compare 30-day mortality in trauma patients after emergency intubation prehospitally or within 30 min after arrival in the trauma centre using either ketamine or propofol for RSI.MethodsIn this investigator-initiated, retrospective study we included adult trauma patients emergently intubated with ketamine or propofol registered in the local trauma registry at Rigshospitalet, a tertiary university hospital that hosts a level-1 trauma centre. The primary outcome was 30-day mortality. Secondary outcomes included hospital and Intensive Care Unit length of stay as well as duration of mechanical ventilation. We analysed outcomes using multivariable logistic regression models adjusting for age, sex, injury severity score, shock (systolic blood pressure < 90 mmHg) and Glasgow Coma Scale score before intubation and present results as odds ratios (ORs) with 95% confidence intervals.ResultsFrom January 1st, 2015 through December 31st, 2019 we identified a total of 548 eligible patients. A total of 228 and 320 patients received ketamine and propofol, respectively. The 30-day mortality for patients receiving ketamine and propofol was 20.2% and 22.8% (P = 0.46), respectively. Adjusted OR for 30-day mortality was 0.98 [0.58–1.66], P = 0.93. We found no significant association between type of induction agent and hospital length of stay, Intensive Care Unit length of stay or duration of mechanical ventilation.ConclusionsIn this study, trauma patients intubated with ketamine did not have a lower 30-day mortality as compared with propofol.

Combination of neuron-specific enolase measurement and initial neurological examination for the prediction of neurological outcomes after cardiac arrest

This study aimed to investigate the efficacy of the combination of neuron-specific enolase (NSE) measurement and initial neurological examination in predicting the neurological outcomes of patients with cardiac arrest (CA) by retrospectively analyzing data from the Korean Hypothermia Network prospective registry. NSE levels were recorded at 48 and 72 h after CA. The initial Full Outline of UnResponsiveness (FOUR) and Glasgow Coma Scale (GCS) scores were recorded. These variables were categorized using the scorecard method. The primary endpoint was poor neurological outcomes at 6 months. Of the 475 patients, 171 (36%) had good neurological outcomes at 6 months. The areas under the curve (AUCs) of the categorized NSE levels at 72 h, GCS score, and FOUR score were 0.889, 0.722, and 0.779, respectively. The AUCs of the combinations of categorized NSE levels at 72 h with categorized GCS scores and FOUR score were 0.910 and 0.912, respectively. Each combination was significantly higher than the AUC value of the categorized NSE level at 72 h alone (with GCS: p = 0.015; with FOUR: p = 0.026). Combining NSE measurement and initial neurological examination improved the prediction of neurological outcomes.

Selection of CT variables and prognostic models for outcome prediction in patients with traumatic brain injury

BackgroundTraumatic brain injuries (TBI) are associated with high risk of morbidity and mortality. Early outcome prediction in patients with TBI require reliable data input and stable prognostic models. The aim of this investigation was to analyze different CT classification systems and prognostic calculators in a representative population of TBI-patients, with known outcomes, in a neurointensive care unit (NICU), to identify the most suitable CT scoring system for continued research.Materials and methodsWe retrospectively included 158 consecutive patients with TBI admitted to the NICU at a level 1 trauma center in Sweden from 2012 to 2016. Baseline data on admission was recorded, CT scans were reviewed, and patient outcome one year after trauma was assessed according to Glasgow Outcome Scale (GOS). The Marshall classification, Rotterdam scoring system, Helsinki CT score and Stockholm CT score were tested, in addition to the IMPACT and CRASH prognostic calculators. The results were then compared with the actual outcomes.ResultsGlasgow Coma Scale score on admission was 3–8 in 38%, 9–13 in 27.2%, and 14–15 in 34.8% of the patients. GOS after one year showed good recovery in 15.8%, moderate disability in 27.2%, severe disability in 24.7%, vegetative state in 1.3% and death in 29.7%. When adding the variables from the IMPACT base model to the CT scoring systems, the Stockholm CT score yielded the strongest relationship to actual outcome. The results from the prognostic calculators IMPACT and CRASH were divided into two subgroups of mortality (percentages); ≤50% (favorable outcome) and > 50% (unfavorable outcome). This yielded favorable IMPACT and CRASH scores in 54.4 and 38.0% respectively.ConclusionThe Stockholm CT score and the Helsinki score yielded the closest relationship between the models and the actual outcomes in this consecutive patient series, representative of a NICU TBI-population. Furthermore, the Stockholm CT score yielded the strongest overall relationship when adding variables from the IMPACT base model and would be our method of choice for continued research when using any of the current available CT score models.

Logistic Regression Analysis of Relationship between Changes of Cerebrospinal Fluid and Communicating Hydrocephalus after Decompressive Craniectomy in Craniocerebral Injury under Computed Tomography Images

This paper aimed to explore the application value of CT imaging in the correlation analysis of communicating hydrocephalus (CH) after decompressive craniectomy (DC) of craniocerebral injury (CI). 410 patients with craniocerebral trauma who were admitted to the hospital from October 2015 to October 2019 were taken as subjects, among which 130 patients suffered from CH. All patients underwent craniocerebral CT examination, and logistic regression was applied to analyze the risk factors of hydrocephalus in CI and hydrocephalus after DC surgery. The results showed that the coma time (OR = 5.1283, P = 0.001 ), subarachnoid hemorrhage (SAH) (OR = 7.6543, P = 0.020 ), Glasgow Coma Scale (GCS) score no more than 8 points (OR = 3.5480, P = 0.001 ), intraventricular hemorrhage (OR = 2.2653, P = 0.003 ), cerebral contusion and laceration (OR = 1.036, P = 0.002 ), and subdural hemorrhage (OR = 2.4376, P = 0.001 ) were independent risk factors for CH. Bilateral DC (OR = 15.342, P = 0.023 ), second surgery (OR = 7.021, P = 0.004 ), bone window height (OR = 6.543, P = 0.041 ), and bone window area (OR = 1.035, P = 0.012 ) were independent risk factors for CH after DC surgery. It suggested that CT imaging technology could be utilized in the diagnosis of CI. The risk factors of CH included coma time, SAH, GCS score no more than 8, intraventricular hemorrhage, brain contusion, subdural hematoma, bilateral DC, bone window height, bone window area, and second surgery.

Factors Predicting Acute Brain Injury in Cases of Carbon Monoxide Poisoning: A Prospective Registry-Based Study.

Carbon monoxide (CO) is one of the most common poisoning substances worldwide. Since acute brain injury (ABI) is an important determinant of the neurological outcome in CO poisoning, screening for patients at a high risk of developing ABI is essential for the proper treatment. This study identified predictors of ABI in patients with CO poisoning. This prospective registry-based study was conducted in patients who visited a tertiary care hospital for CO poisoning from August 2016 to June 2020. ABI was defined as the presence of acute hypoxic lesions on diffusion-weighted magnetic resonance imaging. Multiple logistic regression analysis was performed to identify the predictors of ABI. Of 231 patients, 64 (27.7%) showed ABI. Multiple logistic regression analysis showed that a Glasgow Coma Scale (GCS) score <9 at presentation (odds ratio [OR] 3.28, 95% confidence interval (CI) 1.08–10.01), creatinine level >1.2 mg/dL (OR 3.04, 95% CI 1.16–8.01), and C-reactive protein (CRP) level >9.2 mg/L (OR 4.38, 95% CI 1.41–13.65) predicted ABI in cases of acute CO poisoning. In CO poisoning, the GCS score at presentation, and serum creatinine and CRP levels, were useful predictors of ABI, and may help clinicians identify high-risk patients for whom treatment should be prioritized.

Improvement in Midline Shift Is a Positive Prognostic Predictor for Malignant Middle Cerebral Artery Infarction Patients Undergoing Decompressive Craniectomy.

Objective: The aim of this retrospective study is to evaluate the risk factors of malignant middle cerebral artery infarction (MMCAI) patients and explore an applicable prognostic predictor for MMCAI patients undergoing decompressive craniectomy (DC).Methods: Clinical data from the period 2012–2017 were retrospectively evaluated. Forty-three consecutive MMCAI patients undergoing DC were enrolled in this study. The 30-day mortality was assessed, and age, location, hypertension, pupil dilation, onset to operation duration, midline shift, and Glasgow Coma Scale (GCS) score were identified by univariate analysis and binary logistic regression.Results: In this retrospective study for DC patients, the 30-day mortality was 44.2%. In the univariate analysis, advanced age (≥60 years), right hemispheric location, hypertension, pupil dilation, shorter onset to operation duration (<48 h), improved midline shift (t = 4.214, p < 0.01), and lower pre-operation GCS score were significant predictors of death within 30 days. In binary logistic regression analysis, age [odds ratio (OR) = 1.141, 95% CI 1.011–1.287], the improvement of the midline shift (OR = 0.764, 95% CI 0.59–0.988), and pupillary dilation (OR = 15.10, 95% CI 1.374–165.954) were independent influencing factors. For the receiver operating characteristic (ROC) analysis of the relationship between post-operation outcomes and midline shift improvement, the area under the curve (AUC) was 0.844, and the cutoff point of midline shift improvement was 0.83 cm.Conclusion: Improved midline shift was a significant predictor of 30-day mortality. The improved midline shift of >0.83 cm indicated survival at 30 days.

A Prospective Cohort Study on Serum Sodium and Clinical Outcome in Pediatric Nontraumatic Coma.

To study the serum sodium level and clinical outcome in pediatric nontraumatic coma. A prospective cohort study was conducted in a tertiary care pediatric intensive care unit (PICU) from September 2015 to June 2016. Children aged < 13 y with nontraumatic coma [modified-Glasgow Coma Scale (m-GCS) score ≤ 8 or fall of ≥ 3 from baseline within 24h of admission] were included. Children who received intravenous fluids for > 24h, those with developmental delay, or died within 24h of admission were excluded. The serum sodium profile (mEq/L) in the first 72h and clinical outcome [mortality, length of stay in mechanical ventilation, PICU, and hospital] were studied. Eighty patients [Died n = 26 and Survived n = 54] were enrolled. Median [interquartile range (IQR)] age and m-GCS were 21 (4-78) mo and 9 (7-11), respectively. The mean [standard deviation (SD)] Pediatric Risk of Mortality-III (PRISM-III) was 17.7 (4). The most common etiology was acute central nervous system (CNS) infections (30%, n = 24) followed by an intracranial bleed (11.3%, n = 9). Mean (Standard error, SE) sodium levels and fluctuation of serum sodium from baseline up to 72h were similar between nonsurvivors and survivors [140.8 (1.3) vs. 139.6 (0.8), p = 0.421] and [1.2 (0.3) vs. 0.8 (0.2), p = 0.307], respectively. On multivariate analysis, the need for vasoactive therapy was an independent predictor of mortality [adjusted odds ratio = 20.78, 95% CI 4.24-101.85, p = < 0.001, R2 = 0.62]. Mean serum sodium within normal range and fluctuation of serum sodium of 0.8 to 1.2mEq/L over 72h was not associated with poor outcomes in pediatric nontraumatic coma. Vasoactive therapy was an independent predictor of mortality.

Gastrointestinal failure score in children with traumatic brain injury

BackgroundTo review the value of the gastrointestinal failure (GIF) score in children with different degrees of traumatic brain injury (TBI) by analyzing the correlation between outcome and gastrointestinal function.MethodsA total of 165 children with TBI who were diagnosed and treated in the surgical intensive care unit (SICU) for longer than 72 h between August 2017 and September 2019 were analyzed. Admission parameters included sex, age, Glasgow Coma Scale (GCS) score, body mass index (BMI), leukocyte count, C-reactive protein (CRP), hemoglobin (Hb), hematocrit (Hct), blood glucose, lactic acid, procalcitonin (PCT), albumin, plasma osmotic pressure, prothrombin time (PT) and activated partial thromboplastin time (APTT). To predict outcomes, the Pediatric Sequential Organ Failure Assessment (SOFA) score, Pediatric Clinical Illness Score (PCIS), and mean GIF score for the first three days were combined.ResultsThe percentage of patients with gastrointestinal dysfunction on the first day was 78.8 %. Food intolerance (FI) and intra-abdominal hypertension (IAH) developed in 36.4 and 21.8 % of the patients, respectively. The GIF score and mean GIF score for the first three days were significantly different between children with different degrees of TBI (P < 0.05); these scores were also significantly different between patients who died and those who survived (P < 0.05). The mean GIF score for the first three days was identified as an independent risk factor for mortality (odds ratio > 1, 95 % confidence interval = 1.457 to 16.016, P < 0.01), as was the PCIS. Receiver operating characteristic (ROC) curve analysis suggested that the mean GIF score for the first three days had the same calibrating power as the PCIS in discriminating the risk of death of children.ConclusionsThe incidence of gastrointestinal dysfunction in children with TBI is high. The GIF score has the ability to reflect the status of the gastrointestinal system. The mean GIF score for the first three days has high prognostic value for ICU mortality in the SICU.

Predicting the Health-related Quality of Life in Patients Following Traumatic Brain Injury.

Background Traumatic brain injury (TBI) commonly causes death and disability that can result in productivity loss and economic burden. The health-related quality of life (HRQoL) has been measured in patients suffering from TBI, both in clinical and socioeconomic perspectives. The study aimed to assess the HRQoL in patients following TBI using the European quality of life measure-5 domain-5 level (EQ-5D-5L) questionnaire and develop models for predicting the EQ-5D-5L index score in patients with TBI. Method A cross-sectional study was performed with 193 TBI patients who had completed the EQ-5D-5L questionnaire. The clinical characteristics, Glasgow coma scale (GCS) score, treatment, and Glasgow outcome scale (GOS) were collected. The total data was divided into training data (80%) and testing data (20%); hence, the factors affecting the EQ-5D-5L index scores were used to develop the predictive model with linear and nonlinear regression. The performances of the predictive models were estimated with the adjusted coefficient of determination (R 2 ) and the root mean square error (RMSE). Results A good recovery was found at 96.4%, while 2.1% displayed an unfavorable outcome. Moreover, the mean EQ-5D-5L index scores were 0.91558 (standard deviation [SD] 1.09639). GCS score, pupillary light reflex, surgery, and GOS score significantly correlated with the HRQoL scores. The multiple linear regression model had a high adjusted R 2 of 0.6971 and a low RMSE of 0.06701, while the polynomial regression developed a nonlinear model that had the highest adjusted R 2 of 0.6843 and the lowest RMSE of 0.06748. Conclusions A strong positive correlation between the physician-based outcome as GOS and HRQoL was observed. Furthermore, both the linear and nonlinear regression models were acceptable approaches to predict the HRQoL of patients after TBI. There would be limitations for estimating the HRQoL in unconscious or intubated patients. The HRQoL obtained from the predictive models would be an alternative method to resolve this problem.
