[PMID: 38103392 DOI: 10.1016/j.ajem.2023.11.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 11/17/2023] [Accepted: 11/18/2023] [Indexed: 12/19/2023] Open
Abstract
INTRODUCTION Patients with subdural hemorrhage (SDH) and a Glasgow Coma Scale (GCS) score of 13-15 are typically categorized as having mild traumatic brain injury. We hypothesize that patients without a maximum GCS score - specifically, patients with GCS scores of 13 and 14 - may exhibit poorer neurological outcomes. METHOD Between January 1, 2019, and December 31, 2020, SDH patients with GCS scores ranging from 13 to 15 were retrospectively studied. We compared outcomes between patients with a maximum GCS score of 15 and those with scores of either 13 or 14. Independent factors associated with neurological deterioration among patients with a GCS score of 15 were evaluated using multivariate logistic regression (MLR) analysis. RESULTS During the study period, 470 patients with SDH and GCS scores between 13 and 15 were examined. Compared to patients with a maximum GCS score (N = 375), those in the GCS 13-14 group (N = 95) showed significantly higher rates of neurological deterioration (33.7% vs. 10.4%, p value <0.001) and neurosurgical interventions (26.3% vs. 16.3%, p value <0.024). Moreover, the GCS 13-14 group had a significantly poorer prognosis than patients with a GCS score of 15 [mortality rate: 7.4% vs. 2.4%, p value <0.017; rate of impaired consciousness at discharge: 21.1% vs. 4.0%, p value <0.001; and rate of neurological disability at discharge: 29.5% vs. 6.9%, p value <0.001]. The MLR analysis revealed that SDH thickness (odds ratio = 1.127, p value = 0.006) was an independent risk factor for neurological disability at discharge in patients with a GCS score of 15. CONCLUSION Among SDH patients with mild TBI, those with GCS scores of 13-14 exhibited poorer neurological outcomes than those with a maximum GCS score. The thickness of the SDH is positively associated with neurological disability in SDH patients with a maximum GCS score.

Abstract
Background Decompressive craniectomy or craniotomy is an effective method for reducing intracranial pressure in patients with traumatic brain injury. However, contralateral intracranial hematoma is a rare but serious complication. Recently, the endoscopic technique has been described as a minimally invasive, safe, and effective treatment for intracranial hematoma evacuation. To the best of our knowledge, no technical report has described bilateral traumatic intracerebral hemorrhage (TICH) evacuation using a neuroendoscope. Case Description A 62-year-old man was admitted to the hospital after a fall due to intoxication. His initial Glasgow Coma Scale (GCS) score was 14. Initial computed tomography (CT) revealed a right temporal skull fracture, bilateral frontal and right temporal tip contusions, and acute subdural hematoma. During admission, his condition deteriorated to a GCS score of 6 points, and follow-up CT showed hemorrhagic progression of left frontal and right temporal contusion with midline shift and brainstem compression. Emergency surgery was performed for TICH in the left frontal lobe and right temporal lobe. A burr hole was made in each of the left frontal and right temporal regions, and we used a neuroendoscope to assist in the evacuation of the hematoma. Postoperative CT showed adequate evacuation of the hematoma. The patient regained consciousness and was discharged after 2 months. Conclusion Bilateral TICH was rapidly and sequentially removed by burr-hole craniotomy and endoscopic hematoma evacuation without rapid decompression by craniotomy. The hematoma did not increase. This report demonstrates that the endoscopic-assisted technique allows the safe treatment of bilateral TICH.

Abstract
BACKGROUND Optimal treatment of children with traumatic intracranial epidural hematomas (EDHs) is unknown. We sought to identify clinical and radiographic predictors of delayed surgical intervention among children with EDH admitted for observation. METHODS We retrospectively identified patients younger than 15 years with acute traumatic EDHs evaluated at our level 1 pediatric trauma center. We excluded patients with penetrating head injuries, recent surgical evacuation of EDH, or depressed skull fracture requiring surgical repair and assigned the remaining subjects to the immediate surgery group if they underwent immediate surgical evacuation, to the supportive-therapy-only group if they underwent observation only, and to the delayed surgery group if they underwent surgery after observation. We abstracted clinical and laboratory findings, surgical interventions, and neurological outcome and measured EDH dimensions and volumes, adjusting for cranial size. We compared clinical and radiographic characteristics among groups and performed receiver-operator characteristic analyses of predictors of delayed surgery. RESULTS Of 172 patients with EDH, 103 patients met the inclusion criteria, with 6 (6%) in the immediate surgery group, 87 (84%) in the supportive-therapy-only group, and 10 (10%) in the delayed surgery group. Headache, prothrombin time of >14 seconds, EDH maximal thickness of ≥1.1 cm, volume of ≥14 mL, EDH thickness/cranial width index of ≥0.08 and EDH volume/cranial volume index of ≥0.18, and mass effect were associated with delayed surgical intervention. There was no difference in length of stay or functional impairment between the immediate and delayed surgery groups. However, patients in delayed surgery group were more likely to have subjective symptoms at discharge than those in immediate surgery group. CONCLUSIONS Among patients with EDH admitted for observation, larger EDH, mass effect, headaches, and prothrombin time of >14 seconds were associated with delayed surgical intervention. A larger-scale study is warranted to identify independent predictors of delayed surgery in children under observation for EDH.

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.

Surgical application of endoscopic-assisted minimally-invasive neurosurgery to traumatic brain injury: Case series and review of literature. J Formos Med Assoc 2021; 121:1223-1230. [PMID: 34865948 DOI: 10.1016/j.jfma.2021.11.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 11/01/2021] [Accepted: 11/17/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND/PURPOSE Adequate decompression is the primary goal during surgical management of patients with traumatic brain injury (TBI). Therefore, it may seem counterintuitive to use minimally-invasive strategies to treat these patients. However, recent studies show that endoscopic-assisted minimally-invasive neurosurgery (MIN) can provide both adequate decompression (which is critical for preserving viable brain tissue) and maximize neurological recovery for patients with TBI. Hence, we reviewed the pertinent literature and shared our experiences on the use of MIN. METHODS This was a retrospective multi-center study. We collected data of 22 TBI patients receiving endoscopic-assisted MIN within 72 hours after the onset, with Glasgow Coma Scale (GCS) scores of 6-14 and whose hemorrhage volume ranging from 30 to 70 mL. RESULTS We have applied MIN techniques to a group of 22 patients with traumatic ICH (TICH), epidural hematoma (EDH), and subdural hematoma (SDH). The mean pre-operative GCS score was 7.5 (median 7), and mean hemorrhage volume was 57.14 cm3 Surgery time was shortened with MIN approaches to a mean of 59.6 min. At 6-month follow-up, the mean GCS score had improved to 12.3 (median 15). By preserving more normal brain tissue, MIN for patients with TBI can result in beneficial effects on recoveries and neurological outcomes. CONCLUSION Endoscopic-assisted MIN in TBI is safe and effective in a carefully selected group of patients.

Recalibrating the Glasgow Coma Score as an Age-Adjusted Risk Metric for Neurosurgical Intervention. J Surg Res 2021; 268:696-704. [PMID: 34487962 DOI: 10.1016/j.jss.2021.08.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 07/15/2021] [Accepted: 08/04/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND The Glasgow Coma Scale (GCS) score is the most frequently used neurologic assessment in traumatic brain injury (TBI). The risk for neurosurgical intervention based on GCS is heavily modified by age. The objective is to create a recalibrated Glasgow Coma Scale (GCS) score that accounts for an interaction by age and determine the predictive performance of the recalibrated GCS (rGCS) compared to the standard GCS for predicting neurosurgical intervention. METHODS This retrospective cohort study utilized the National Trauma Data Bank and included all patients admitted from 2010-2015 with TBI (ICD9 diagnosis code 850-854.19). The study population was divided into 2 subsets: a model development dataset (75% of patients) and a model validation dataset (remaining 25%). In the development dataset, logistic regression models were used to calculate conditional probabilities of having a neurosurgical intervention for each combination of age and GCS score, to develop a point-based risk score termed the rGCS. Model performance was examined in the validation dataset using area under the receiver operating characteristic (AUROC) curves and calibration plots. RESULTS There were 472,824 patients with TBI. The rGCS ranged from 1-15, where rGCS 15 denotes the baseline risk for neurosurgical intervention (4.4%) and rGCS 1 represents the greatest risk (62.6%). In the validation dataset there was a statistically significant improvement in predictive performance for neurosurgical intervention for the rGCS compared to the standard GCS (AUROC: 0.71 versus 0.67, difference, -0.04, P<0.001), overall and by trauma level designation. The rGCS was better calibrated than the standard GCS score. CONCLUSIONS The relationship between GCS score and neurosurgical intervention is significantly modified by age. A revision to the GCS that incorporates age, the rGCS, provides risk of neurosurgical intervention that has better predictive performance than the standard ED GCS score.

Abstract
PURPOSE Most mild traumatic brain injuries (TBIs) can be treated conservatively. However, some patients deteriorate during observation. Therefore, we tried to evaluate the characteristics of deterioration and requirement for further management in mild TBI patients. METHODS From 1/1/2017 to 12/31/2017, patients with mild TBI and positive results on CT scans of the brain were retrospectively studied. Patients with and without neurological deteriorations were compared. The characteristics of mild TBI patients with further neurological deterioration or the requirement for interventions were delineated. RESULTS One hundred ninety-two patients were enrolled. Twenty-three (12.0%) had neurological deteriorations. The proportions of deterioration occurring within 24 h, 48 h and 72 h were 23.5, 41.2 and 58%, respectively. Deteriorated patients were significantly older than those without neurological deteriorations (69.7 vs. 60.2; p = 0.020). More associated extracranial injuries were observed in deteriorated patients [injury severity score (ISS): 20.2 vs. 15.9; p = 0.005). Significantly higher proportions of intraventricular hemorrhage (8.7 vs. 1.2%; p = 0.018) and multiple lesions (78.3 vs. 53.8%; p = 0.027) were observed on the CT scans of patients with neurological deteriorations. Subset analysis showed that deteriorated patients who required neurosurgical interventions (N = 7) had significantly more initial GCS defects (13 or 14) (71.4 vs. 12.5%; p = 0.005) and more initial decreased muscle power of extremities (85.7 vs. 18.8%; p = 0.002). CONCLUSION More attention should be given to mild TBI patients with older age, GCS defects, decreased muscle power of the extremities, multiple lesions on CT scans and other systemic injuries (high ISS). Most deteriorations occur within 72 h after trauma.

Abstract
Introduction Mild traumatic brain injury (TBI) is common but its management is variable. Objectives To describe the acute natural history of isolated hemorrhagic mild TBI. Methods This was a single-center, retrospective chart review of 661 patients. Inclusion criteria were consecutive patients with hemorrhagic mild TBI. Exclusion criteria were any other acute traumatic injury and significant comorbidities. Variables recorded included neurosurgical intervention and timing, mortality, emergency room disposition, intensive care unit (ICU) length of stay (LOS), discharge disposition, repeat computed tomography head (CTH) indications and results, neurologic exam, age, sex, Glasgow Coma Scale (GCS) score, and hemorrhage type. Results Overall intervention and unexpected delayed intervention rates were 9.4% and 1.5%, respectively. The mortality rate was 2.4%. A 10-year age increase had 26% greater odds of intervention (95% CI, 9.6-45%; P<.001) and 53% greater odds of mortality (95% CI, 11-110%; P=.009). A one-point GCS increase had 49% lower odds of intervention (95% CI, 25-66%; P<.001) and 50% lower odds of mortality (95% CI, 1-75%; P=.047). Subdural and epidural hemorrhages were more likely to require intervention (P=.02). ICU admission was associated with discharge to an acute care facility (OR, 2.9; 95% CI, 1.4-6.0; P=.003). Neurologic exam changes were associated with a worsened CTH scan (OR, 12.3; 95% CI, 7.0-21.4; P<.001) and intervention (OR, 15.1; 95% CI, 8.4-27.2; P<.001). Conclusions Isolated hemorrhagic mild TBI patients are at a low, but not clinically insignificant, risk of intervention and mortality.

Abstract
Intraoperative and postoperative effects of platelet transfusion on antiplatelet drug-related intracerebral hemorrhage (ICH) patients were investigated. A retrospective study on 82 ICH patients undergoing emergency surgical treatment caused by antiplatelet drugs was conducted. Among them, 51 patients treated with platelet transfusion served as the observation group and 31 patients without platelet transfusion as the control group. The intraoperative and postoperative bleeding volume, blood transfusion volume and the rate of secondary bleeding were compared between observation and control group under the guidance of thromboelastography (TEG). The coagulation routine examination results of the two groups before surgery were in the normal range, but TEG indicated an excessive inhibition of platelet function (platelet inhibition rate >89%). The platelet number after treatment increased significantly in the two groups of patients and it was significantly higher in observation group than that in control group (P<0.05). The intraoperative bleeding volume in observation group was significantly lower than that in control group. The total blood transfusion volume in observation group was significantly lower than that in control group (Z=2.681, P=0.036), the postoperative hematoma residual volume in observation group was significantly lower than that in control group (t=2.145, P=0.035), and the drainage volume in observation group was significantly lower than that in control group (t=2.401, P=0.019). Only 3.92% of the patients in observation group and 19.35% in control group had secondary surgery, and the difference of the recurrence rate of secondary bleeding between the two groups was statistically significant (χ2=3.610, P=0.048). TEG detection indicator can more comprehensively and accurately evaluate the preoperative coagulation function of patients. This study suggests that preoperative platelet transfusion can improve the intraoperative and postoperative bleeding of ICH patients after antiplatelet therapy to some extent, reducing the blood transfusion volume and the secondary bleeding rate.

Abstract
OBJECTIVE Isolated subdural hematomas (iSDHs) are one of the most common intracranial hemorrhage (ICH) types in the population with mild traumatic brain injury (mTBI; Glasgow Coma Scale score 13-15), account for 66%-75% of all neurosurgical procedures, and have one of the highest neurosurgical intervention rates. The objective of this study was to examine how quantitative hemorrhage characteristics of iSDHs in patients with mTBI at admission are associated with subsequent neurosurgical intervention. METHODS This was a 3.5-year, retrospective observational cohort study at a Level I trauma center. All adult trauma patients with mTBI and iSDHs were included in the study. Maximum length and thickness (in mm) of acute SDHs, the presence of acute-on-chronic SDH, mass effect, and other hemorrhage-related variables were double-data entered; discrepant results were adjudicated after a maximum of 4 reviews. Patients with coagulopathy, skull fractures, no acute hemorrhage, a non-SDH ICH, or who did not undergo imaging on admission were excluded. The primary outcome was neurosurgical intervention (craniotomy, burr hole, catheter drainage of SDH, placement of intracranial pressure monitor, shunt, or ventriculostomy). Multivariate stepwise logistic regression was used to identify significant covariates and to assess interactions. RESULTS A total of 176 patients were included in our study: 28 patients did and 148 patients did not receive a neurosurgical intervention. Increasing head Abbreviated Injury Scale score was significantly associated with neurosurgical interventions. There was a strong correlation between the first 3 reviews on maximum hemorrhage length (R2 = 0.82) and maximum hemorrhage thickness (R2 = 0.80). The neurosurgical intervention group had a mean maximum SDH length and thickness that were 61 mm longer and 13 mm thicker than those of the nonneurosurgical intervention group (p < 0.001 for both). After adjusting for the presence of an acute-on-chronic hemorrhage, for every 1-mm increase in the thickness of an iSDH, the odds of a neurosurgical intervention increase by 32% (95% CI 1.16-1.50). There were no interventions for any SDH with a maximum thickness ≤ 5 mm on initial presenting scan. CONCLUSIONS This is the first study to quantify the odds of a neurosurgical intervention based on hemorrhage characteristics in patients with an iSDH and mTBI. Once validated in a second population, these data can be used to better inform patients and families of the risk of future neurosurgical intervention, and to evaluate the necessity of interhospital transfers.

Abstract
OBJECTIVE A paucity of studies have examined neurosurgical interventions in the mild traumatic brain injury (mTBI) population with intracranial hemorrhage (ICH). Furthermore, it is not understood how the dimensions of an ICH relate to the risk of a neurosurgical intervention. These limitations contribute to a lack of treatment guidelines. Isolated subdural hematomas (iSDHs) are the most prevalent ICH in mTBI, carry the highest neurosurgical intervention rate, and account for an overwhelming majority of all neurosurgical interventions. Decision criteria in this population could benefit from understanding the risk of requiring neurosurgical intervention. The aim of this study was to quantify the risk of neurosurgical intervention based on the dimensions of an iSDH in the setting of mTBI. METHODS This was a 3.5-year, retrospective observational cohort study at a Level I trauma center. All adult (≥ 18 years) trauma patients with mTBI and iSDH were included in the study. Maximum length and thickness (in mm) of acute SDHs, the presence of acute-on-chronic (AOC) SDH, mass effect, and other hemorrhage-related variables were double-data entered; discrepant results were adjudicated after a maximum of 4 reviews. Patients with coagulopathy, skull fractures, no acute hemorrhage, a non-SDH ICH, or who did not undergo imaging on admission were excluded. Tentorial SDHs were not measured. The primary outcome was neurosurgical intervention (craniotomy, burr holes, intracranial pressure monitor placement, shunt, ventriculostomy, or SDH evacuation). Multivariate stepwise logistic regression was used to identify significant covariates, to assess interactions, and to create the scoring system. RESULTS There were a total of 176 patients included in our study: 28 patients did and 148 did not receive a neurosurgical intervention. There were no significant differences between neurosurgical intervention groups in 11 demographic and 22 comorbid variables. Patients with neurosurgical intervention had significantly longer and thicker SDHs than nonsurgical controls. Logistic regression identified thickness and AOC hemorrhage as being the most important variables in predicting neurosurgical intervention; SDH length was not. Risk of neurosurgical intervention was calculated based on the SDH thickness and presence of an AOC hemorrhage from a multivariable logistic regression model (area under the receiver operating characteristic curve 0.94, 95% CI 0.90-0.97; p < 0.001). With a decision point of 2.35% risk, we predicted neurosurgical intervention with 100% sensitivity, 100% negative predictive value, and 53% specificity. CONCLUSIONS This is the first study to quantify the risk of neurosurgical intervention based on hemorrhage characteristics in patients with mTBI and iSDH. Once validated in a second population, these data can be used to inform the necessity of interhospital transfers and neurosurgical consultations.

Abstract
The optimal management of mild traumatic brain injury (TBI) patients with injuries identified by computed tomography (CT) brain scan is unclear. Some guidelines recommend hospital admission for an observation period of at least 24 h. Others argue that selected lower-risk patients can be discharged from the Emergency Department (ED). The objective of our review and meta-analysis was to estimate the risk of death, neurosurgical intervention, and clinical deterioration in mild TBI patients with injuries identified by CT brain scan, and assess which patient factors affect the risk of these outcomes. A systematic review and meta-analysis adhering to PRISMA standards of protocol and reporting were conducted. Study selection was performed by two independent reviewers. Meta-analysis using a random effects model was undertaken to estimate pooled risks for: clinical deterioration, neurosurgical intervention, and death. Meta-regression was used to explore between-study variation in outcome estimates using study population characteristics. Forty-nine primary studies and five reviews were identified that met the inclusion criteria. The estimated pooled risk for the outcomes of interest were: clinical deterioration 11.7% (95% confidence interval [CI]: 11.7%-15.8%), neurosurgical intervention 3.5% (95% CI: 2.2%-4.9%), and death 1.4% (95% CI: 0.8%-2.2%). Twenty-one studies presented within-study estimates of the effect of patient factors. Meta-regression of study characteristics and pooling of within-study estimates of risk factor effect found the following factors significantly affected the risk for adverse outcomes: age, initial Glasgow Coma Scale (GCS), type of injury, and anti-coagulation. The generalizability of many studies was limited due to population selection. Mild TBI patients with injuries identified by CT brain scan have a small but clinically important risk for serious adverse outcomes. This review has identified several prognostic factors; research is needed to derive and validate a usable clinical decision rule so that low-risk patients can be safely discharged from the ED.

Abstract
OBJECTIVE To outline differences in neurosurgical intervention (NI) rates between intracranial hemorrhage (ICH) types in mild traumatic brain injuries and help identify which ICH types are most likely to benefit from creation of predictive models for NI. METHODS A multicenter retrospective study of adult patients spanning 3 years at 4 U.S. trauma centers was performed. Patients were included if they presented with mild traumatic brain injury (Glasgow Coma Scale score 13-15) with head CT scan positive for ICH. Patients were excluded for skull fractures, "unspecified hemorrhage," or coagulopathy. Primary outcome was NI. Stepwise multivariable logistic regression models were built to analyze the independent association between ICH variables and outcome measures. RESULTS The study comprised 1876 patients. NI rate was 6.7%. There was a significant difference in rate of NI by ICH type. Subdural hematomas had the highest rate of NI (15.5%) and accounted for 78% of all NIs. Isolated subarachnoid hemorrhages had the lowest, nonzero, NI rate (0.19%). Logistic regression models identified ICH type as the most influential independent variable when examining NI. A model predicting NI for isolated subarachnoid hemorrhages would require 26,928 patients, but a model predicting NI for isolated subdural hematomas would require only 328 patients. CONCLUSIONS This study highlighted disparate NI rates among ICH types in patients with mild traumatic brain injury and identified mild, isolated subdural hematomas as most appropriate for construction of predictive NI models. Increased health care efficiency will be driven by accurate understanding of risk, which can come only from accurate predictive models.

Abstract
OBJECTIVE To evaluate the need for repeat head computed tomography (CT) in patients with complicated mild traumatic brain injury (TBI) determined nonoperative after the first head CT. METHODS A total of 380 patients with mild TBI and a positive head CT not needing surgery were included. Changes between first and second head CT were categorized as decreased, increased, or stable. RESULTS Three patients required neurosurgical intervention (0.8%) after the second CT. There were no significant differences in demographics including age, gender, alcohol consumption, anticoagulation status, time between first and second CT, Glasgow Coma Scale score at admission and discharge, and incidence of subarachnoid hemorrhage, epidural hematoma, contusion, or skull fractures between the operated and nonoperated groups. All patients in the operated group had subdural hematoma compared with 40.8% in the nonoperated group (P = 0.07). All operated patients showed symptoms of neurologic worsening after initial head CT, compared with 2.7% in the nonoperated group (P < 0.001). Moreover, patients who showed neurologic worsening were more likely to show increased intracranial bleeding on repeat head CT, whereas patients who did not show neurologic worsening were more likely to show decreased or stable intracranial bleeding (P = 0.04). CONCLUSIONS Routine repeat head CT in patients with complicated mild TBI is very low yield to predict need for delayed surgical intervention. Instead, serial neurologic examination and observation over the first 8 hours after the injury is recommended. A second CT scan should be obtained only in patients who have neurologic worsening.
