Introduction: Traumatic brain injury (TBI) is a common neurosurgical emergency and a common public health problem with high mortality and long term morbidity. The cost incurred by TBI is immense. The major determinant of outcome following TBI is the severity of the primary injury. However, secondary injuries including coagulopathy are treatable prognostic factors. Many studies have revealed that coagulopathy of trauma depicted by increasing level of D-dimer is associated with poor prognosis in TBI. So, early dectection and correction of such abnormality is very important in management of TBI.Methods: This is a prospective observational study conducted at Department of Surgery TUTH (Tribhuvan University Teaching Hospital), Kathmandu,Nepal over a period of one year. One hundred and forty eight patients of TBI were included in the study. Clinical profile of the patients and D-dimer level were monitored during the hospital course. D-dimer level was correlated with outcome variables including duration of hospital stay, duration of Intensive care unit (ICU) stay and Glasgow outcome scale (GOS).Results: A total of 194 patients were admitted with the diagnosis of traumatic brain injury during the study period and out of them 148 patients were enrolled for the study. Out of 148 patients one hundred and twenty (81.1%) were males and twenty eight (18.9%) were females. The mean age was 29.71±18.07 and the age ranged from 1 to 78 years. Seventy (47.3%) patient were between 21 to 40 years of age. The mean duration of hospital stay was 9.83±13.58 days and the mean duration of ICU stay was 3.78±7.06 days. Contusion was the most common lesion in our patients. Of the patients studied 111 patients (75%)  had good recovery with GOS of 5, 9  patients (6.1%)  had GOS of 4, 6 patients (4.1%)  had GOS of 3, 1 patients (0.7%)  had GOS of 2 and 21 patients (14.1%)  had GOS of 1. Normal D-dimer was seen in 102 patients (68.9%) and elevated D-dimer in 46 patients (31.1%). Man –Whitney test shows higher D-dimer levels positively correlated with duration of hospital stay, duration of ICU stay and Glasgow Outcome Scale. Pearson chi-square test revealed higher levels of D-dimer correlated with grade of injury but not with mode of injury.Conclusion: D-dimer is elevated in significant proportion of patients with TBI and abnormal D-dimer level is associated with poor outcome in TBI.Journal of Society of Surgeons of Nepal Vol.17(1) 2014: 21-30

Abstract Introduction Traumatic brain injury (TBI) affects the coagulation pathway in a distinct way than does extracranial trauma. The extent of coagulation abnormalities varies from bleeding diathesis to disseminated thrombosis. Design Prospective study. Methods The study included 50 patients of isolated TBI with cohorts of moderate (MHI) and severe head injury (SHI). Coagulopathy was graded according to the values of parameters in single laboratory. The incidence of coagulopathy according to the severity of TBI and correlation with disseminated intravascular coagulation (DIC) score, platelets, prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, and fibrinogen was observed. The comparison was also made between expired and discharged patients within each group. It also compared coagulation derailments with clinical presentation (Glasgow Coma Scale [GCS]) and outcome (Glasgow Outcome Scale [GOS]). Results Road traffic accident was the primary (72%) mode of injury. Fifty-two percent had MHI and rest had SHI. Eighty-four percent of cases were managed conservatively. The mean GCS was 12.23 and 5.75 in MHI and SHI, respectively. Sixty-two percent of MHI and 96% of the patients with SHI had coagulation abnormalities. On statistical analysis, DIC score (p < 0.001) strongly correlated with the severity of head injury and GOS. PT and APTT were also significantly associated with the severity of TBI. In patients with moderate TBI, D-dimer and platelet counts showed association with clinical outcome. Fibrinogen levels did not show any statistical significance. The mean platelet counts remained normal in both the groups of TBI. The mean GOS was 1.54 and 4.62 in SHI and MHI, respectively. Conclusion Coagulopathy is common in isolated TBI. The basic laboratory parameters are reliable predictors of coagulation abnormalities in TBI. Coagulopathy is directly associated with the severity of TBI, GCS, and poor outcome.

ABSTRACT:BACKGROUND & OBJECTIVE: To compare the results of surgically operated vs conservatively treated patients of cerebral contusions due to traumatic brain injury. METHODOLOGY: This comparative study was conducted from January 2012 to December 2014 at the department of Neurosurgery, PGMI Lahore General Hospital, Lahore. A total of 50 patients were included in this study of both gender (male and female) and in the age range of 15-65 years. In our study 20 patients were managed conservatively while other 30 patients were operated for cerebral contusions. The mode of injury in our study was road traffic accidents and history of falls. RESULTS: Out of 50 patients, there were 41 (82%) males and 09 (18%) female patients. Their age ranged from 15 - 65 years. In this study the overall mean age is 38.36 years. The maximum numbers of patients were in their third and fourth decades of life. In our study the duration of hospital stay in conservatively managed patients was longer as compared to surgically treated patients who were discharged earlier. Mortality rate in surgically managed patients having a GCS ranged between 09 to 12 was very low contrary to the conservatively managed group, similarly the rate of delayed contusion formation and edema was also low in surgically managed patients as compared to those who were managed conservatively. CONCLUSION: Surgically managed patients of cerebral contusions in traumatic brain injury has better outcome and decreased hospital stay as compared to conservatively managed patients.

OBJECTIVECerebral ventriculitis remains one of the most challenging neurosurgical conditions, with poor outcome and a long course of treatment and duration of hospital stay. Despite the current conventional management plans, i.e., using antibiotics in addition to CSF drainage, the outcome remains unsatisfactory in some cases, with no definitive therapeutic guidelines. This study aims to compare the outcome of ventricular irrigation/lavage (endoscopic irrigation or the double-drain technique) to conventional currently accepted therapy using just drainage and antibiotics.METHODSThe authors conducted a prospective controlled study in 33 patients with cerebral ventriculitis in which most of the cases were complications of CSF shunt operations. Patients were divided into two groups. Removal of the ventricular catheter whenever present was performed in both groups. The first group was managed by ventricular lavage/irrigation, while the other group was managed using conventional therapy by inserting an external ventricular drain. Both systemic and intraventricular antibiotics were used in both groups. The outcomes were compared regarding mortality rate, modified Rankin Scale (mRS) score, and duration of hospital stay.RESULTSThe mean age of the study population was 5.98 ± 7.02 years. The mean follow-up duration was 7.6 ± 3.2 months in the conventional group and 5.7 ± 3.4 months in the lavage group. The mortality rate was 25% (4/16) in the lavage group and 52.9% (9/17) in the nonlavage group (p = 0.1). The mRS score was less than 3 (good outcome) in 68.8% (11/16) of the lavage group cases and in 23.5% (4/17) of the conventional group (p < 0.05). The mean hospital stay duration was 20.5 ± 14.2 days in the lavage group, whereas it was 39.7 ± 16.9 days in the conventional group (p < 0.05).CONCLUSIONSVentricular lavage or irrigation together with antibiotics is useful in the management of cerebral ventriculitis and associated with a better outcome and shorter hospital stay duration compared to current conventional lines of treatment.

ObjectiveThis study aimed to evaluate the duration of intensive care unit (ICU) stay prior to onset of invasive candidiasis (IC)/candidaemia.DesignSystematic review and meta-analysis.Data sourcesPubMed, Cochrane, Embase and Web of Science databases were searched through June 2019 to identify relevant studies.Eligibility criteriaAdult patients who had been admitted to the ICU and developed an IC infection.Data extraction and synthesisThe following data were extracted from each article: length of hospital stay, length of ICU stay, duration of ICU admission prior to candidaemia onset, percentage of patients who received antibiotics and duration of their antibiotic therapy prior to candidaemia onset, and overall mortality. In addition to the traditional meta-analyses, meta-regression was performed to explore possible mediators which might have contributed to the heterogeneity.ResultsThe mean age of patients ranged from 28 to 76 years across selected studies. The pooled mean duration of ICU admission before onset of candidaemia was 12.9 days (95% CI 11.7 to 14.2). The pooled mean duration of hospital stay was 36.3±5.3 days (95% CI 25.8 to 46.7), and the pooled mean mortality rate was 49.3%±2.2% (95% CI 45.0% to 53.5%). There was no significant difference in duration of hospital stay (p=0.528) or overall mortality (p=0.111), but a significant difference was observed in the mean length of ICU stay (2.8 days, p<0.001), between patients with and without Candida albicans. Meta-regression analysis found that South American patients had longer duration of ICU admission prior to candidaemia onset than patients elsewhere, while those in Asia had the shortest duration.ConclusionsPatients with IC are associated with longer ICU stay, with the shortest duration of ICU admission prior to the candidaemia onset in Asia. This shows a more proactive strategy in the diagnosis of IC should be considered in caring for ICU patients.

Abstract Objectives Neurosurgeons working in the vicinity of tribal areas face traumatic brain injury (TBI) cases due to bear maul which is on the rise in Chhattisgarh. Most of the literature is focused on the management of maxillofacial injuries. This study intends to describe the challenges in management and outcomes of TBI due to bear maul. Materials and Methods A retrospective review was conducted from May 2018 to April 2020. The patients without TBI were excluded. The variables studied were age, gender, timing and mode of conflict, Glasgow coma scale (GCS) at arrival, injury spectrum, hospital stay, the modified Rankin score (MRS), mini mental status examination (MMSE), and surgical site infections (SSI). Results Twenty-eight patients were eligible for analysis. The mean age of presentation was 40.67 ± 13.99 years. There were 23 males (82.15%). Most common time of attack was during dawn (n = 11, 39.28%) followed by dusk (n = 9, 32.14%) and day (n = 8, 28.57%) time. Provoked conflicts were seen in 64.28%. The mean preoperative GCS was 11.07 ± 3.54 and hospital stay was 18.71 ± 9.51 days. Skull fractures were found in 24/28 (85.71%). The mean MRS was 1.67 ± 1.38 at a mean follow-up of 14.53 ± 6.59 months. Favorable outcome (MRS ≤ 2) was seen in 64.28% of patients. The mean MMSE score was 22.28 ± 5.36. Eight patients developed SSI (28.57%). Conclusion Outcomes of TBI due to bear maul depend on preoperative GCS. There are higher incidences of skull fractures and SSI. Humans need to avoid infiltration in wildlife territory to reduce the number of conflicts.

Introduction: Sodium imbalance in post-traumatic brain injury is not uncommon. It’s early detection and treatment is vital as it increases morbidity and mortality if not treated on time. We study the effect of Sodium imbalance as a predictor of outcome in these patients. Methods and Materials: Patients diagnosed with traumatic brain injury (TBI) admitted to Neurosurgery department were included in this study. Traumatic brain injury cases managed between 1st Baisakh 2074 B.S. and 29th Chaitra 2074 B.S. were analyzed prospectively.  Glasgow Coma Scale, Computed Tomography scan of head, duration of hospital and Intensive Care Unit (ICU) stay, and Glasgow Outcome Scale in relation to sodium imbalance measured within 24 hours of injury were assessed. Mortality and morbidity were measured using Glasgow Outcome Scale (GOS). Results: A total of 100 patients with traumatic brain injury admitted in the Neurosurgery department of Bir Hospital were included in this study. Sixty seven cases were categorized as mild, 18 as moderate and 15 as severe according to the severity of TBI. The maximum serum sodium level observed was 168 and lowest was 110 mmol/l. The association of sodium imbalance with severity of head injury was found to be statistically significant. The sensitivity of sodium imbalance measured within 24 hours of injury in prognosticating outcome of patient till death or before discharge from hospital on the basis of GOS and Neuro ICU stay day is significant with p value <0.05. Conclusion: Sodium imbalance is an independent prognostic factor outcome in TBI. Continuous monitoring of sodium level in the neurosurgical ICU setting is mandatory to manage patients with head injury with or without undergoingneurosurgical intervention as it has prognostic value with outcome measures like GOS and ICU stay days.

The Relationship

External ventricular drainage (EVD) is widely used in patients with a traumatic brain injury (TBI). However, the EVD weaning trial protocol varies and insufficient studies focus on the intracranial pressure (ICP) during the weaning trial. We aimed to establish the relationship between ICP during an EVD weaning trial and the outcomes of TBI. We enrolled 37 patients with a TBI with an EVD from July 2018 to September 2019. Among them, 26 were allocated to the favorable outcome group and 11 to the unfavorable outcome group (death, post-traumatic hydrocephalus, persistent vegetative state, and severe disability). Groups were well matched for sex, pupil reactivity, admission Glasgow Coma Scale score, Marshall computed tomography score, modified Fisher score, intraventricular hemorrhage, EVD days, cerebrospinal fluid output before the weaning trial, and the complications. Before and during the weaning trial, we recorded the ICP at 1-hour intervals to calculate the mean ICP, delta ICP, and ICP burden, which was defined as the area under the ICP curve. There were significant between-group differences in the age, surgery types, and intensive care unit days (p=0.045, p=0.028, and p=0.004, respectively). During the weaning trial, 28 (75.7%) patients had an increased ICP. Although there was no significant difference in the mean ICP before and during the weaning trial, the delta ICP was higher in the unfavorable outcome group (p=0.001). Moreover, patients who experienced death and hydrocephalus had a higher ICP burden, which was above 20 mmHg (p=0.016). Receiver operating characteristic analyses demonstrated the predictive ability of these variables (area under the curve AUC=0.818 [p=0.002] for delta ICP and AUC=0.758 [p=0.038] for ICP burden>20 mmHg). ICP elevation is common during EVD weaning trials in patients with TBI. ICP-related parameters, including delta ICP and ICP burden, are significant outcome predictors. There is a need for larger prospective studies to further explore the relationship between ICP during EVD weaning trials and TBI outcomes.

OBJECTIVEFew studies have reported on changes in quantitative cerebral blood flow (CBF) after decompressive craniectomy and the impact of these measures on clinical outcome. The aim of the present study was to evaluate global and regional CBF patterns in relation to cerebral hemodynamic parameters in patients after decompressive craniectomy for traumatic brain injury (TBI).METHODSThe authors studied clinical and imaging data of patients who underwent xenon-enhanced CT (XeCT) CBF studies after decompressive craniectomy for evacuation of a mass lesion and/or to relieve intractable intracranial hypertension. Cerebral hemodynamic parameters prior to decompressive craniectomy and at the time of the XeCT CBF study were recorded. Global and regional CBF after decompressive craniectomy was measured using XeCT. Regional cortical CBF was measured under the craniectomy defect as well as for each cerebral hemisphere. Associations between CBF, cerebral hemodynamics, and early clinical outcome were assessed.RESULTSTwenty-seven patients were included in this study. The majority of patients (88.9%) had an initial Glasgow Coma Scale score ≤ 8. The median time between injury and decompressive surgery was 9 hours. Primary decompressive surgery (within 24 hours) was performed in the majority of patients (n = 18, 66.7%). Six patients had died by the time of discharge. XeCT CBF studies were performed a median of 51 hours after decompressive surgery. The mean global CBF after decompressive craniectomy was 49.9 ± 21.3 ml/100 g/min. The mean cortical CBF under the craniectomy defect was 46.0 ± 21.7 ml/100 g/min. Patients who were dead at discharge had significantly lower postcraniectomy CBF under the craniectomy defect (30.1 ± 22.9 vs 50.6 ± 19.6 ml/100 g/min; p = 0.039). These patients also had lower global CBF (36.7 ± 23.4 vs 53.7 ± 19.7 ml/100 g/min; p = 0.09), as well as lower CBF for the ipsilateral (33.3 ± 27.2 vs 51.8 ± 19.7 ml/100 g/min; p = 0.07) and contralateral (36.7 ± 19.2 vs 55.2 ± 21.9 ml/100 g/min; p = 0.08) hemispheres, but these differences were not statistically significant. The patients who died also had significantly lower cerebral perfusion pressure (52 ± 17.4 vs 75.3 ± 10.9 mm Hg; p = 0.001).CONCLUSIONSIn the presence of global hypoperfusion, regional cerebral hypoperfusion under the craniectomy defect is associated with early mortality in patients with TBI. Further study is needed to determine the value of incorporating CBF studies into clinical decision making for severe traumatic brain injury.
