Description d'un protocole de prise en charge préhospitalière du traumatisé crânien grave

[Epidemiological aspects and prognostic factors of severe traumatic brain injuries]

OBJECTIVE

To determine the severity factors in severe traumatic brain injuries.

METHODS

A prospective descriptive study of severe head injuries admitted to the emergency department at Ibn Tofail Hospital at the University Hospital of Marrakech over a period of six months from May to October 2015. The following data was collected: circumstances, clinical, biology, radiology, treatment and evolution.

RESULTS

One hundred and nineteen patients with severe traumatic brain injury were collected (101 males, 84,9%). The mean age was 37,73±15,7 years. Road accidents were the most common cause representing 84%. The median Glasgow coma scale (GCS) was 7±3. We noted 36 cases (30,3%) of anisocoria, 32 cases (26,9%) of bilateral mydriasis and 72 cases (60,5%) of hypoxia. Cerebral contusions (66,1%) and meningeal hemorrhage (66,6%) were the most frequent lesions on CT. Forty-seven patients (42%) had stage VI Marshall lesions. Twenty-four patients (20.1%) required a neurosurgical intervention, 12 extradural hematoma evacuations and 10 craniocerebral wounds. Mortality was 64.7% (77 deaths), the main cause was neurological (64,9%). In the latter group, we observed more frequently an older age (P=0.00001), a management delay (P=0.011), a low initial GCS (P=0.000001), a bilateral nonreactive mydriasis (P=0.0001), a hypoxia (P=0.0002), a subarachnoid hemorrhage (P=0.008), a high Marshall score (P=0.017) and an anemia (P=0.046).

CONCLUSION

Head trauma is a public health problem. The victims are young, and the sequelae are frequently disabling. Several parameters are associated with a poorer prognosis including age, neurological state and the initial delay in management.

Mortality in Children With Severe Head Trauma: Predictive Factors and Proposal for a New Predictive Scale

BACKGROUND

Traumatic brain injury is a public health problem around the world, and recognition of systemic sources of secondary brain lesions is crucial to improve outcome.

OBJECTIVE

To identify the main predictors of mortality and to propose a grading scale to measure the risk of death.

METHODS

This retrospective study was based on medical records of children with severe traumatic brain injury who were hospitalized at a level I pediatric trauma center between January 2000 and December 2005. Multiple logistic regression analysis was done to identify independent factors related to mortality. A receiver-operating characteristics curve was performed to verify the accuracy of the multiple logistic regression, and associations that increased mortality were verified.

RESULTS

We identified 315 children with severe head injury. Median Glasgow Coma Scale score was 6, and median Pediatric Trauma Score was 4. Global mortality rate was 30%, and deaths occurred despite adequate medical management within the first 48 hours in 79% of the patients. Age < 2 years (P = .02), Glasgow Coma Scale ≤ 5 (P < 10), accidental hypothermia (P = .0002), hyperglycemia (P = .0003), and coagulation disorders (P = .02) were all independent factors predicting mortality. A prognostic scale ranging from 0 to 6 that included these independent factors was then calculated for each patient and resulted in mortality rates ranging from 1% with a score of 6 to 100% with a score of 0.

CONCLUSION

Independent and modifiable mortality predictors could be identified and used for a new grading scale correlated with the risk of mortality in pediatric traumatic brain injury.

Clinical and critical care concerns of cranio-facial trauma: A retrospective study in a tertiary care institute

Background and Objectives:

Maxillofacial trauma is commonly associated with other injuries, predominantly head injuries. The predictors of outcome in such concomitant injuries have been studied the least. The present study aims at the evaluation of types of injury, management and outcome of patients sustaining maxillofacial trauma and concomitant cranial injuries.

Materials and Methods:

A retrospective study was carried out in the department of anesthesiology and intensive care. A case series of 129 patients was evaluated who were admitted in ICU (Intensive Care Unit) with maxillofacial trauma and head injuries. The data was then compiled systematically and analyzed using SPSS windows and value of P < 0.05 was considered significant and P < 0.001 as highly significant.

Results:

Among the 129 patients, majority of them had roadside accidents (RSA > 90%) and male gender predominance with male to female ratio of 5: 1. Fracture maxilla and nasal bones were the most commonly encountered injuries (51.93%) followed by mandibular fractures (39.53%) and fracture of zygomatic bones (28.68%). Eighty five patients (65.90%) required mechanical ventilation, tracheostomy was needed in 29 (22.48%) patients and 81 (62.8%) patients were operated for head injuries as well. Majority of the victims were aged between 15 and 40 years.

Conclusions:

Maxillofacial trauma and cranial injuries are common among young males and so is the nature of injuries, that is, RSA. Besides facial injuries, head injuries are important determinant of outcome in such patients. Timely resuscitation and surgical interventions at specialized centers are of prime importance as far as a better prognosis is concerned in such injuries.

Acute hyperglycemia is a reliable outcome predictor in children with severe traumatic brain injury

PURPOSE

Hyperglycemia in the acute phase after trauma could adversely affect outcome in children with severe traumatic brain injury (TBI). The goal of this study was to identify the relationship between acute spontaneous hyperglycemia and outcome in children with severe TBI at hospital discharge and 6 months later.

METHODS

A retrospective analysis of blood glucose levels in children with severe TBI at a Pediatric level I Trauma Center, between January 2000 and December 2005. Hyperglycemia was considered for a cut-off value of 11.1 mmol/l (200 mg/dl). Outcome was measured with Glasgow Outcome Scale (GOS) at hospital discharge and at 6 months. A multiple logistic regression analysis, the Student's t test and the chi (2) test were done.

RESULTS

Hyperglycemia was noted within the first 48 h in 34% of the patients. Mortality (70% vs 14%, p < 10(-5)) was more frequent in hyperglycemic children and bad outcome upon hospital discharge in those who remained hyperglycemic during the first 48 h of hospitalization. GOS after 6 months demonstrated that those normoglycemic children had a better outcome (95%) than those who developed hyperglycemia during the first 48 h (83%, p = 0.01) after trauma.

CONCLUSION

Hyperglycemia could be considered as a marker of brain injury and when present upon admission, could reflect extensive brain damage with frequently associated mortality and bad outcome. The inability to maintain normal blood glucose levels during the first 48 h could be a predictive factor of bad outcome. Avoiding hyperglycemia in the initial phase could be a major issue in children with severe TBI.

Defenestration in children younger than 6 years old: mortality predictors in severe head trauma

PURPOSE

This study aims to describe the characteristics of severe head injuries in children less than 6 years old, victims of falls from windows, and identify the main predictive factors of mortality in this population.

PATIENTS AND METHODS

A cross-sectional study was designed through data derived from medical records of less than 6-year-old children victims of falls from windows presenting with a severe head injury defined by an initial Glasgow coma scale (GCS) < or =8, hospitalized at a Pediatric Trauma center level III, between January 2000 and December 2005. Statistical analysis used univariate analysis and multiple logistic regressions.

RESULTS

We identified 58 severe head injuries in children victims of falls from windows. The mean age was 2.8 +/- 1.4 years, with a male prevalence (64%); 48% of patients had a GCS < or =5; 62.1% had a Pediatric Trauma Score (PTS) < or =3 at hospital admission. The mortality rate was 41% (24/58) and most of them (88%; 21/24) died within 48 h. An increased death rate was noted in children admitted with hypoxemia (p = 0.001), low systolic blood pressure (p = 0.002), hypothermia (p = 0.0001), GCS < or =5 (p = 10(-5)), PTS < or =3 (p = 0.008), hyperglycemia (p = 0.023), coagulation disorders (p = 0.02), and initial intracranial pressure > or =20 mmHg (p = 0.03). Initial hypothermia, hyperglycemia, and coagulation disorders were the only independent predictive factors of mortality.

CONCLUSION

Severe head injuries resulting from falls from windows carry a high risk of mortality in less than 6-year-old children. Hypothermia, hyperglycemia, and coagulation's disorders are independent predictive factors of mortality. Early deaths could be considered as direct consequences of uncontrollable brain lesions.

Thiopental vs. etomidate for rapid sequence intubation in aeromedicine

INTRODUCTION

Although there is a general agreement that rapid sequence intubation (RSI) is the preferred technique for intubation in aeromedical care, several pharamacological regimens have been employed without clear evidence of which is superior.

HYPOTHESIS

This study was designed to compare the use of etomidate (ETOM) with that of thiopental (THIO) as an adjunctive agent used with succinylcholine (SCh) for RSI in an urban, aeromedical system.

METHODS

This was a retrospective, before-and-after study utilizing computer-assisted chart review. Adult patients who received THIO for RSI over a two-year period were compared to adult patients who received ETOM for RSI over a similar period, after a change in protocol, which mandated ETOM rather than THIO for all intubations.

RESULTS

No difference was found in any of the primary endpoints. Stabilization time (13.1 vs. 12.9 minutes), number of intubation attempts (1.1 vs. 1.2), successful first intubation attempts (90% vs. 82%), overall successful intubations (100% vs. 96%), and intubation time (18.4 vs. 21.7 seconds) were similar for all comparisons of THIO vs. ETOM (all p > 0.05).

CONCLUSION

This study found no clinically relevant differences between the use of ETOM or THIO as adjuncts with SCh for RSI in the aeromedical setting.

Should we use etomidate as an induction agent for endotracheal intubation in patients with septic shock?: a critical appraisal

Etomidate is commonly used for the facilitation of endotracheal intubation. While etomidate possesses multiple qualities that are beneficial in hemodynamically unstable patients who require a sedative or amnestic, its potential to negatively impact corticosteroid production is well-documented. Given the frequency of relative adrenal insufficiency observed in the critically ill and the increasing use of corticosteroids in patients with septic shock, an appraisal of the status of etomidate as an induction agent in patients with evolving or established septic shock is indicated. A review of the relevant literature suggests that its use in this setting may be harmful. It is proposed that, pending the performance of a randomized, controlled clinical trial, considerable caution should accompany its administration in patients with evolving or established septic shock. The potential role for concomitant empiric steroid replacement and the comparability of alternative induction regimens are also discussed.
