Abstract
Traumatic brain injury (TBI) describes parenchymal brain damage caused by external forces to the head. It has a massive personal and socioeconomic impact, as it is a disease with high morbidity and mortality. Both young and old people are affected, as a result of traffic or sports accidents as well as due to falls at home. The term TBI encompasses various clinical pictures, differing considerably in cause, prognosis and therapy. What they all have in common is the pathophysiological cascade that develops immediately after the initial trauma and which can persist for several days and weeks. In this phase, medical treatment, whether surgical or pharmacological, attempts to reduce the consequences of the primary damage. The aim is to maintain adequate cerebral perfusion pressure and to reduce intracranial pressure.

Choi DH, Jeong TS, Kim WK. Clinical Outcome of Patients Diagnosed Traumatic Intracranial Epidural Hematoma With Severe Brain Injury (Glasgow Coma Scale ≤8) Who Undergo Surgery: A Report From the Korean Neuro-Trauma Data Bank System. Korean J Neurotrauma 2022; 18:153-160. [PMID: 36381437 PMCID: PMC9634314 DOI: 10.13004/kjnt.2022.18.e62] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 09/26/2022] [Accepted: 10/06/2022] [Indexed: 08/19/2023] Open
Abstract
OBJECTIVE To evaluate the clinical outcomes and prognostic factors in surgically treated patients with severe brain injury (Glasgow Coma Scale [GCS] score ≤8) diagnosed with traumatic epidural hematoma (EDH). METHODS From January 2018 to June 2021, 1,122 patients with an initial GCS score ≤8 were retrospectively enrolled in the Korean Neuro-Trauma Data Bank System. Clinical data of 79 surgically treated patients with EDH were compared between the unfavorable (scores of 1-4 on the Glasgow Outcome Scale-Extended [GOSE]) and favorable (score of 5-8 on the GOSE) outcome groups. RESULTS The overall mortality rate was 13.9%, and 60.8% of the patients had good outcomes at six months post-trauma. In the univariate analysis, increasing age (p=0.010), lower initial GCS score (p=0.001), higher Rotterdam computed tomography (CT) score (p=0.012), craniotomy rather than craniectomy (p=0.032), larger EDH volume (p=0.007), and loss of pupillary reactivity (unilateral unreactive pupil, p=0.026; bilateral unreactive pupils, p<0.001), were significantly correlated with unfavorable outcomes. Of these factors, increasing age (p=0.011) and bilateral unreactive pupils (p=0.002) were the most significant risk factors in the multivariate logistic regression analysis. The interval from admission to the brain CT scan was not correlated with the outcome; however, it was significantly longer in the unfavorable outcome group. CONCLUSION Despite severe brain injury, more than half of the patients with EDH had favorable outcomes after surgical treatment. Our findings suggest that prompt diagnosis and surgical treatment should be considered for such cases.

The unmet global burden of cranial epidural hematomas: A systematic review and meta-analysis. Clin Neurol Neurosurg 2022; 219:107313. [PMID: 35688003 DOI: 10.1016/j.clineuro.2022.107313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 05/25/2022] [Accepted: 05/27/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVE Approximately 69 million people suffer from traumatic brain injury (TBI) annually. Patients with isolated epidural hematomas (EDH) with access to timely surgical intervention often sustain favorable outcomes. Efforts to ensure safe, timely, and affordable access to EDH treatment may offer tremendous benefits. METHODS A comprehensive literature search was conducted. A random-effects model was used to pool the outcomes. Studies were further categorized into groups by World Bank Income classification: high-income countries (HICs) and low- and middle-income countries (LMICs). RESULTS Forty-nine studies were included, including 36 from HICs, 12 from LMICs, and 1 from HIC / LMIC. Incidence of EDH amongst TBI patients 8.2 % (95 % CI: 5.9,11.2), including 9.2 % (95 %CI 6.4,13.2) in HICs and 5.8 % (95 % CI: 3.1,10.7) in LMICs (p = 0.20). The overall percent male was 73.7 % and 47.4 % were caused by road traffic accidents. Operative rate was 76.0 % (95 %CI: 67.9,82.6), with a numerically lower rate of 74.2 % (95 %CI: 64.0,81.8) in HICs than in LMICs 82.9 % (95 %CI: 65.4,92.5) (p = 0.33). This decreased to 55.5 % after adjustment for small study effect. The non-operative mortality (5.3 %, 95 %CI: 2.2,12.3) was lower than the operative mortality (8.3 %, 95 %CI: 4.6,14.6), with slightly higher rates in HICs than LMICs. This relationship remained after adjustment for small study effect, with 9.3 % operative mortality compared to 6.9 % non-operative mortality. CONCLUSION With an overall EDH incidence of 8.2 % and an operative rate of 55.5 %, 3.1 million people worldwide require surgery for traumatic EDH every year, most of whom are in prime working age. Given the favorable prognosis with treatment, traumatic EDH is a strong investment for neurosurgical capacity building.

Abstract
To evaluate the teaching effect of a trauma training program in emergency cranial neurosurgery in Cambodia on surgical outcomes for patients with traumatic brain injury (TBI). We analyzed the data of TBI patients who received emergency burr-hole trephination or craniotomy from a prospective, descriptive cohort study at the Military Region 5 Hospital between January 2015 and December 2016. TBI patients who underwent emergency cranial neurosurgery were primarily young men, with acute epidural hematoma (EDH) and acute subdural hematoma (SDH) as the most common diagnoses and with long transfer delay. The incidence of favorable outcomes three months after chronic intracranial hematoma, acute SDH, acute EDH, and acute intracerebral hematoma were 96.28%, 89.2%, 93%, and 97.1%, respectively. Severe traumatic brain injury was associated with long-term unfavorable outcomes (Glasgow Outcome Scale of 1–3) (OR = 23.9, 95% CI: 3.1–184.4). Surgical outcomes at 3 months appeared acceptable. This program in emergency cranial neurosurgery was successful in the study hospital, as evidenced by the fact that the relevant surgical capacity of the regional hospital increased from zero to an acceptable level.

Abstract
INTRODUCTION Controversy and variation exist in surgical management for acute epidural haematoma (AEDH). Although craniotomy for AEDH is conventionally employed, no specific evaluation on the necessity of decompressive craniectomy (DC) followed by AEDH evacuation has been performed. METHODS AND ANALYSIS This is a multicentre prospective, phase III observational study that evaluates different surgical managements for the AEDH. Patients of both genders, aged 18-65 years, presenting to the emergency room with a clinical and radiological diagnosis of AEDH, complying with other inclusion and exclusion criteria, are enrolled. Clinical information, including diagnosis of AEDH, radiological information, treatment procedures and follow-up data of 1, 3 and 6 months post-injury, is collected on 2000 eligible patients among 263 hospitals in China. Recruitment for the study started in April 2021, and inclusion will be continued until the sample size is obtained, expected is an inclusion period of 24 months. The interventions of concern are surgical treatments for AEDH, including craniotomy and DC. The primary outcome is the Glasgow Outcome Score-Extended 6 months post-injury. Secondary outcomes include the incidence of postoperative cerebral infarction, the incidence of additional craniocerebral surgery and other evaluation indicators within 6 months post-injury. ETHICS AND DISSEMINATION The study protocol has been approved by the ethics committee and institutional review board of Renji Hospital, School of Medicine, Shanghai Jiao Tong University. All study investigators strictly follow the Declaration of Helsinki and Human Biomedical Research Ethical Issues. Signed written informed consent will be obtained from all enrolled patients. The trial results will be disseminated through academic conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT04229966.

Location of Traumatic Cranial Epidural Hematoma Correlates with the Source of Hemorrhage: A 12-Year Surgical Review. World Neurosurg 2021; 152:e138-e143.

Abstract
BACKGROUND Epidural hematoma (EDH) can result in a catastrophic outcome of traumatic brain injury. Current management guidelines do not consider the source of hemorrhage in decision making. The purpose of this study was to examine the relationship between EDH location and the source of hemorrhage. METHODS We report retrospectively reviewed, prospectively obtained surgical data of patients with acute traumatic cranial EDH treated between 2007 and 2018. Computed tomography (CT) scans were used to categorize EDH location as lateral or medial. The source of hemorrhage was identified intraoperatively by a single surgeon. RESULTS Overall, of 92 evacuated EDHs (in 87 patients), 71 (77.2%) were in the lateral location. Arterial bleeding was the cause of EDH in 63.4% of the lateral EDHs and 9.2% of the medial EDHs (P < 0.0001). In the cases where surgery was done primarily to treat EDH, 65.3% had an arterial bleed source (P < 0.0001). In those treated for primary reasons other than EDH evacuation, 75% had a venous bleed source (P = 0.002). CONCLUSIONS The location of EDH correlates with the source of hemorrhage. The decision to operate on EDH may be influenced by this factor.

Abstract
Epidural hematomas (EDHs) and subdural hematomas (SDHs), or so-called extra-axial bleedings, are common clinical entities after a traumatic brain injury (TBI). A forensic pathologist often analyzes cases of traumatic EDHs or SDHs due to road accidents, suicides, homicides, assaults, domestic or on-the-job accidents, and even in a medical responsibility scenario. The aim of this review is to give an overview of the published data in the medical literature, useful to forensic pathologists. We mainly focused on the data from the last 15 years, and considered the most updated protocols and diagnostic-therapeutic tools. This study reviews the epidemiology, outcome, and dating of extra-axial hematomas in the adult population; studies on the controversial interdural hematoma are also included.

Abstract
BACKGROUND Epidural hematomas (EDHs) involving the venous sinuses are uncommon and carry the risk of hemorrhage or venous infarction. We report the largest case series for superior sagittal sinus- and transverse sinus-related EDHs including surgical and nonsurgical management. We compare our findings to the relevant literature. METHODS A retrospective review of the EDH cases at our center was performed from 2013-2018. Patients were analyzed by surgical versus conservative management, outcomes, and complications. RESULTS Of the 268 EDH patients identified, 32 involved the venous sinuses (23 supratentorial and 9 infratentorial). Ten of the patients had surgery, and 22 were managed conservatively. No surgical complications occurred, and all had a Glasgow Outcome Scale score of 5 at follow-up. All of the nonsurgical patients had a Glasgow Outcome Scale score of 4 or 5 at follow-up except for 1 patient with prior disability. The literature search resulted in 39 infratentorial and 47 supratentorial EDHs involving venous sinuses. CONCLUSIONS Surgical and nonsurgical management of EDHs involving the venous sinuses are both viable options with good outcomes. Surgical intervention is based on location, size, neurologic examination, expansion on serial imaging, and vascular imaging findings. Surgery has the potential for significant complications, but all surgical patients in our series had good outcomes at follow-up. Similarly, nonsurgically managed patients had good outcomes and our overall series demonstrates better outcomes with fewer complications than other similar series in the literature.

Abstract
Near-infrared spectroscopy (NIRS) is emerging as a rapid, low-cost approach for point-of-care triage of hematomas resulting from traumatic brain injury. However, there remains a lack of standardized test methods for benchtop performance assessment of these devices and incomplete understanding of relevant light-tissue interactions. We propose a phantom-based test method for systems operating near the 800-nm oxy-/deoxy-hemoglobin isosbestic point and implement it to evaluate a clinical system. Semi-idealized phantom geometries are designed to represent epidural/subdural, subarachnoid, and intracerebral hemorrhages. Measurements of these phantoms are made with a commercial NIRS-based hematoma detector to quantify the effect of hematoma type, depth, and size, as well as measurement repeatability and detector positioning relative to the hematoma. Results indicated high sensitivity to epidural/subdural and subarachnoid hematomas. Intracerebral hematomas are detectable to a maximum depth of ∼2.5 cm, depending on thickness and diameter. The maximum lateral detection area for the single-emitter/single-collector device studied here appears elliptical and decreases strongly with inclusion depth. Overall, this study provides unique insights into hematoma detector function and indicates the utility of modular polymer tissue phantoms in performance tests for emerging NIRS-based cerebral diagnostic technology.

Abstract
The formation of a post-traumatic delayed epidural hematoma (DEDH) is a rare but well-described complication in the literature. It is defined as an extradural bleeding not evident at the first computed tomography (CT) scan performed after trauma, but evidenced by further radiological evaluations. The most supported hypothesis about the mechanism responsible for the formation of a DEDH concerns above all the loss of a tamponade effect given by the reduction of intracranial pressure with medical or surgical treatment. A 30-year-old man was admitted to the emergency department with an epidural hematoma (EDH) associated with a linear calvarial bitemporal coronal fracture. A few hours after the surgical procedure for hematoma evacuation, the patient developed a DEDH contralateral to the site of surgical procedure. The literature review identified other 27 analogue cases. The presence of a calvarial fracture contralateral to the site of a craniotomy and the intraoperative brain swelling during EDH removal are suspicious for the development of DEDH. A CT scan has to be urgently performed in this situation. The timing of postoperative radiological examinations after EDH removal has to consider possible complications and has to be balanced on the basis of patient's clinical condition and neuroradiological data, such as skull fractures or intraoperative anomalies. The development of a DEDH after the surgical removal of an EDH is a rare event, characterized by a high mortality rate. DEDH develops preferentially on the contralateral side and with a concomitant skull fracture.

Abstract
Infratentorial traumatic intracranial bleeds (ICBs) are rare and the distribution of subtypes is unknown. To characterize this distribution the National Trauma Data Bank (NTDB) 2014 was queried for adults with single type infratentorial ICB, n = 1,821: subdural hemorrhage (SDH), subarachnoid hemorrhage (SAH), epidural hemorrhage (EDH), and intraparenchymal hemorrhage (IPH). Comparisons were made between the groups with statistical significance determined using chi squared and t-tests. SDH occurred in 29% of patients, mostly in elderly on anti-coagulants (13%) after a fall (77%), 42% of them underwent craniotomy, their mortality was the lowest (4%). SAH was the most common (56%) occurring mostly from traffic related injuries (27%). Furthermore, 9% of them had a severe head injury Glasgow Coma Scale ≤8 (GCS), but had the lowest Injury Severity Score (ISS, median 8) as well as a short hospital length of stay, 5.1 ± 6.2 days. These patients were most likely to be discharged to home (64%). They had the lowest mortality (4%). EDH was the least common ICB (5%), occurred in younger patients (median age 49 years), and it had the highest percentage of associated injuries (13%). EDH patients presented with the poorest neurological status (26% GCS ≤8, ISS median 25) and were operated on more than any other ICB type (55%). EDH was the highest mortality (9%) ICB type and had a low discharge to home rate (58%). IPH was uncommon (10%). Infratentorial bleeds types have different clinical courses, and outcomes. Understanding these differences can be useful in managing these patients.

The cost-effectiveness of epidural, patient-controlled intravenous opioid analgesia, or transversus abdominis plane infiltration with liposomal bupivacaine for postoperative pain management. J Clin Anesth 2018; 53:56-63. [PMID: 30326379 DOI: 10.1016/j.jclinane.2018.10.003] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 09/29/2018] [Accepted: 10/07/2018] [Indexed: 12/27/2022]
Abstract
STUDY OBJECTIVE Intravenous patient-controlled opioid analgesia (IVPCA), epidural analgesia and transversus abdominis plane (TAP) infiltrations are frequently used postoperative pain management modalities. The aim of this study was to conduct a cost-effectiveness analysis comparing the use of epidural, IVPCA, and TAP infiltrations with liposomal bupivacaine for analgesia in the first 72 h postoperatively in patients undergoing major lower abdominal surgery. DESIGN Retrospective cost effectiveness analysis. SETTING Operating room. PATIENTS We obtained data on major lower-abdominal surgeries performed under general anesthesia on adult patients between January 2012 and July 2014. INTERVENTIONS A cost-effectiveness analysis was comparing the use of epidural, IVPCA, and TAP infiltrations with liposomal bupivacaine for analgesia in the first 72 h postoperatively. MEASUREMENTS A decision analytic model was used to estimate the health outcomes for patients undergoing major lower abdominal surgery. The primary outcome was time-weighted pain from 0 to 72 h after surgery, as measured by numerical rating scale pain scores. The analysis was conducted from the perspective of the hospital as the party responsible for most costs related to surgery. MAIN RESULTS From the base case analysis, IVPCA was the optimal strategy regarding cost and effect. TAP with LB, however, was only narrowly dominated, while epidural was clearly dominated. From the sensitivity analysis at willingness-to-pay (WTP) of $150, IV PCA and TAP infiltration were each the optimal strategy for approximately 50% of the iterations. At WTP of $10,000, epidural was only the optimal strategy in 10% of the iterations. CONCLUSIONS This is the first study in the literature to compare the cost-effectiveness of epidural, IVPCA, and TAP infiltrations with LB. Within reasonable WTP values, there is little differentiation in cost-effectiveness between IVPCA and TAP infiltration with LB. Epidural does not become a cost-effective strategy even at much higher WTP values.
