[Special aspects of the emergency medical care of head and neck injuries]

The overall incidence of severe head, face and neck injuries as seen from the German Trauma Registry of the National Association of German Trauma Surgeons is 81.3%. The leading causes of death among these patients are hemorrhage and severe traumatic brain injury. The aim of prehospital emergency medical care is to stabilize vital functions in order to ensure primary survival and to reduce morbidity with appropriate prehospital treatment of the individual injuries within the overall injury pattern. In this review, special aspects as well as pitfalls of the prehospital management of patients with head, face and neck injuries are demonstrated. Prehospital airway management concepts as well as concepts for stopping bleeding in the head, face and neck region are discussed in detail.

Utility of routine follow-up head CT scanning after mild traumatic brain injury: a systematic review of the literature

OBJECTIVE

To evaluate the efficacy of routine follow-up CT scans of the head after complicated mild traumatic brain injury (TBI).

METHODS

74 English language studies published from 1999 to February 2011 were reviewed. The papers were found by searching the PubMed database using a combination of keywords according to Cochrane guidelines. Excluding studies with missing or inappropriate data, 1630 patients in 19 studies met the inclusion criteria: complicated mild TBI, defined as a GCS score 13-15 with abnormal initial CT findings and the presence of follow-up CT scans. For these studies, the progression and type of intracranial haemorrhage, time from trauma to first scan, time between first and second scans, whether second scans were obtained routinely or for neurological decline and the number of patients who had a neurosurgical intervention were recorded.

RESULTS

Routine follow-up CT scans showed hemorrhagic progression in 324 patients (19.9%). Routine follow-up head CT scans did not predict the need for neurosurgical intervention (p=0.10) but a CT scan of the head performed for decline in status did (p=0.00046). For the 56 patients (3.4%) who declined neurologically, findings on the second CT scan were worse in 38 subjects (67%) and unchanged in the rest. Overall, 39 patients (2.4%) underwent neurosurgical intervention.

CONCLUSION

Routine follow-up CT scans rarely alter treatment for patients with complicated mild TBI. Follow-up CT scans based on neurological decline alter treatment five times more often than routine follow-up CT scans.

[Factors indicative of differentiated approach to the treatment of severe focal lesions of the brain]

The article is devoted the study of complex research 126 patients with a heavy craniocerebral trauma, accompanied vnutrimozgovoy traumatic haematoma and hearth crushing of cerebrum, passing treatment in the clinic of neuro-surgery. The use of modern diagnostic methods of research considerably changed the informative providing of diagnostic and medical process at the different hearth defeats of cerebrum, including traumatic hearth injuries of cerebrum. The long-term looking after intracraneal haematomas allowed to mark that haematomas suffer successive changes which are expressly traced on computer tomography researches in course of time.

Neuroanesthesiology review--2006

In this article, we will provide a review of the 2006 literature of interest to those readers who provide perioperative care to patients with neurologic disease. This evaluation of the literature is not intended to be comprehensive, nor were systematic criteria used to include or exclude articles. Instead, the authors attempted to highlight those articles of greatest clinical relevance or those that provided unique insights into the physiology, pharmacology, and pathomechanisms of neurologic function for practicing clinicians and clinician-investigators. This article focuses on intracranial hemorrhage, anesthetic considerations in neurosurgical patients, cerebral hemodynamics, electrophysiologic monitoring, neuroprotection, and traumatic brain injury.

[Uncontrollable bleeding in a patient with head trauma treated with blood component therapy guided by thromboelastography]

This is a case report concerning a patient with traumatic uncontrolled bleeding. The patient was admitted with a severe head injury and facial fractures. During neurosurgery, the bleeding became life-threatening and there was a request for recombinant factor VIIa therapy (NovoSeven). Before the treatment, thromboelastography was performed. This showed platelet insufficiency, and after infusion of platelets, the bleeding was under control and there was no longer a need for recombinant factor VIIa therapy. We therefore recommend thromboelastography to evaluate coagulation status before treatment with recombinant factor VIIa.

Does routine serial computed tomography of the head influence management of traumatic brain injury? A prospective evaluation

BACKGROUND

Computed tomography (CT) of the head is the current standard for diagnosing intracranial pathology following blunt head trauma. It is common practice to repeat the head CT to evaluate any progression of injury. Recent retrospective reviews have challenged the need for serial head CT after traumatic brain injury (TBI). This study intends to prospectively examine the value of routine serial head CT after TBI.

METHODS

Consecutive adult blunt trauma patients with an abnormal head CT admitted to an urban, Level I trauma center from January 2003 to September 2003 were prospectively studied. Variables collected included: initial head CT results, indication for repeat head CT (routine versus neurologic change), number and results of repeat head CT scans, and clinical interventions following repeat head CT.

RESULTS

Over the 9-month period, there were 128 patients admitted with an abnormal head CT after sustaining blunt trauma. The 16 patients who died within 24 hours and the 12 patients who went directly to craniotomy were excluded. The remaining 100 patients make up the study population. Abnormal head CT findings were subarachnoid hemorrhage (47%), intraparenchymal hemorrhage (37%), subdural hematoma (28%), contusion (14%), epidural hematoma (11%), intraventricular hemorrhage (3%), and diffuse axonal injury (2%). Overall, 32 patients (32%) had only the admission head CT, while 68 patients (68%) underwent 90 repeat CT scans. Of the repeat head CT scans, 81 (90%) were performed on a routine basis without neurologic change. The remaining 9 (10%) were performed for a change in Glasgow Coma Scale (n = 5), change in intracranial pressure (n = 1), change in Glasgow Coma Scale and intracranial pressure (n = 1), change in pupil size (n = 1), or sudden appearance of a headache (n = 1). Three patients had their care altered after repeat head CT: two underwent craniotomy and one was started on barbiturate therapy. All three patients had their repeat head CT after neurologic change (decrease in Glasgow Coma Scale in 2 and increase in intracranial pressure in 1).

CONCLUSIONS

Serial head CT is common after TBI. Most repeat head CT scans are performed on a routine basis without neurologic change. Few patients with TBI have their management altered after repeat head CT, and these patients have neurologic deterioration before the repeat head CT. The use of routine serial head CT in patients without neurologic deterioration is not supported by the findings of this study.

[Cerebral circulatory autoregulation as a guide for controlling the parameters of assisted ventilation in acute severe brain injury]

The paper presents the results of cerebral circulation (CC) in 17 ventilated patients with severe brain injury in its acute phase. All the patients developed traumatic subarachnoidal hemorrhage, which was accompanied with angiospasm in the majority of cases. Doppler transcranial study (DTCS) was performed, by using the carotid compression test; the findings correlated with paCO2 and CV parameters. A dynamic study was performed every two days starting from their admission to an intensive care unit to the recovery from coma or normalization of CC parameters. The dilation and constriction components of the CC reserve were assessed from the results of this test and continued to be controlled during therapy. Thus, this paper shows the possibility of goal-oriented correction of CC autoregulation and optimization by selecting the parameters of assisted ventilation and by changing paCO2 under the guidance of Doppler transcranial study.

Cutaneous stimulation improves function of a chronic patient with cerebellar damage

The prognosis of cerebellar hemorrhage with brain stem compression is known to be poor, and patients who can usually survive are severely disabled with limited benefit from conventional rehabilitation. An innovative cutaneous stimulation was administered to a chronic patient (2 years after the incidence) who has severe ataxia, gait imbalance and limb spasticity caused by cerebellar hemorrhage. After 8 months of intervention, patient's function as evaluated by two functional measures has improved by 40%. In addition, the patient's ataxia and hypotonia have improved significantly in which he has regained the abilities to grasp objects, sit upright, control his equilibrium, and monitor an electric wheelchair. The present case study demonstrated a significant improvement of a chronic severely disabled patient who received the intervention 2 years after the accident, suggesting that the cutaneous stimulation may be a possible effective neurologic intervention.
