Importance of the theme Neurotraumatism is one of the important sections of modern medicine. Trauma of CNS constitutes 30-40 % in the general structure of traumatism, and death rate in the young and middle age considerably exceeds vascular and oncological diseases in peace, time, and also is a principal cause of death in wartime. This problem has not only medical, but also a big social significance as the level of traumatism tends to grow staidly. 2. The aims of the class: 2.1 The educational aims of the class 1. The student should know about an epidemiology of cranial brain trauma, the social importance of the problem, a history of studying this section of neurosurgery, biomechanism of the CCCT. I level 2. The student should know etiopathogenesis of the CCCT, classification, principles of diagnostics and modern methods of examination of patients, the main kinds of conservative and operative treatment, and early both late complications and methods of their treatment, principles of rehabilitation and social adaptation. II level 3. The student should be able to render the urgent aid at a place of accident, to determine a kind of the CCCT, to examine, estimate the received results of examination, to diagnose and define tactics of treatment. To master skills of surgical treatment of the wound, of 2 controling bleeding, technique of carrying out a lumbar puncture, assistance in cranial trepanation, as well to fill in the medical documentation correctly. III-IV a level 2.2 The educational aims To give a notion of importance of neurotraumatology being one of the key problems of modern medicine. To form preventive orientations of clinical thinking. To form a notion of the responsibility for timely and correct professional actions, system of the legal notions connected with treatment of patients with CCCT. To be able to carry out the deontologycal approach to casualties, to master a skill of establishing psychological contact with the patient and his relatives. 3.

Contents of the class Discussion of main principles of diagnostics of traumatic injuries of the skull and brain. Significance of the anamnesis, the data of objective examination and auxiliary methods of diagnostics at definition of a kind of a craniocerebral trauma. Rendering assistance by the patient with the closed craniocerebral trauma at a pre-hospital stage of treatment. The description by students of X-ray films with single and multiple linear and splintered fractures of the skull. Demonstration of slides, preparations of bruises, compressions of the brain, macroscopic signs of dislocations of the brain. Selection by students of the instruments necessary for rendering urgent aid to the patient with the closed craniocerebral trauma. Analysis of the patients with concussion, compression and contusion of the brain. Discussion of pathomorphologic changes in a brain, determination of the kind of injury. The analysis of the general cerebral and focal manifestations, characteristic of various kinds of the CCCT. Significance of auxiliary methods of diagnostics of the CCCT. While discussing patients supervised by students differential diagnostics is made, medical tactics, volume of conservative treatment is defined(determined) on clinical examples. The compression of the brain can be caused by intracranial haematomas (epidural, subdural, intracerebral, intra-ventricular), hydromas, the pressed-in fractures, and also by growing edema of the brain, pneumocephalus. TREATMENT of intracranial haematomas is SURGICAL, osteoplastic and resectional cranial trepanations. Complications of CCT. Abscess - a cavity filled with pus and delimited by a capsule from the brain substance. Layers of the abscess: 4 zone of disintegration; granulation a layer (vessels are located radially in it); fibrous (several circularly located vessels); perifocal zone. The capsule is formed from vessels, hence, the deeper the abscess is located in the white substance, the thinner is it capsule. The capsule is the thickest in the cortex. Microbes: more often it is staphylococci (the thickest capsule), diplococci, coli facillus. Pathogenesis: an embolus - ischemia - microbes with walls of the vessel - vasculitis perivasculitis - distribution of the abscess. Kinds of abscess perforation: microperforation - abscesses as "cluster of grapes"; macroperforation - abscesses can perforate in the brain substance, in ventricles of the brain, in to the subarachnoidal space. By terms of occurrence there are early (till 3 months) and late (after 3 months) abscesses. The capsule of the abscess is formed not earlier than 3-6 weeks. Till this time it is possible to wash it out with solutions of antiseptics and antibiotics (Canamycin, Levomycetin, Gentamycin) through a fistula and drainage. As a result of it the cavity is formed which is then removed, or the cavity is closed gradually by itself and pushes out a drainage. This tactics is acceptable in deeply located abscesses. Kinds of a surgery: drainage; puncture; total removal. The clinical picture of the early abscess develops from general brain and focal symptoms. Late abscesses have a course as: apoplexies: sudden development of general brain symptoms. More often death occurs the first 24 hours. Blood and the eye fundus can not react in any way. 5 By the course there are acute the period, latent, marked clinical manifestation (or - early manifestation, latent manifestation of the abscess, terminal. The latent period is a silent course of the abscess). pseudotumorous variant of the course. Blood does not react. On the eye fundus stagnation is determined. The general brain and focal manifestations gradually grow. More than 50 % of all abscesses are accompanied by epileptic attacks. In 30 % of cases they are first signs of the abscess. They have s course as the general and focal generalized attacks. There is marked polymorphism of attacks (multifoci in a trauma and growth of the abscess). Diagnostics: examination of the head; anamnesis; R-graphy of the skull; Echoencephalography; investigation of the eye fundus; EEG - in development of seizures (only for lateralization of the process); angiography, CT-SCAN, MRI, scintigraphy. LATE COMPLICATIONS OF CCT - THE POSTTRAUMATIC EPILEPSY Epilepsy is a pathological excitation of the brain accompanying by convulsive or convulsive-free attack. Factors: convulsive readiness of the brain; presence of the epileptogenic center - cicatrices (cerebral, meningeal - cerebral, it is cutaneous - meningeal-cerebral); consequences of the inflammatory process; development of subarachnoidal cysts (inflammation, subarachnoidal haemorrhages); presence of foreign bodies (a bone, a bullet, splinters, soft tissues); hydrocephalus of the brain. 6 Structure of epileptic attacks: great the general the patient - suddenly loses consciousness, falls, the face reddens, the tonic spasms passing in to clonicoues, cyanosis of integuments, involuntary urination. the focal - always there is an aura (motor, sensor, psychosensor, vegetative) Jackson attacks without loss of consciousness and without generalization of spasms (motor and sensor) - convulsive discharge in some group of muscles, paresthesias in some extremity. It upper parietal lobule is affected the attack proceeds by hemitype. psychosensor equivalents - petit mall - short-term, loss of consciousness for 20-30 seconds without any convulsive component and without falling down. Phases of formation of the cicatrix of the brain: glial, argirophil, collagenic. Examination of the patient with seizures: R-graphy of the skull in two projections; EEG - acute wave are determined in the focus. In irritation (by light, sound, hyperventilation, bemegrid 1 ml, thyopental sodium - slower waves are determined in the focus) Indications to the operation: morphological cicatrices; abscesses; foreign bodies; the pressed-in fractures; adhesive or cystic arachnoiditis clinical absence of effect of medicamentous treatment at often attacks; progredient course of the disease; increasing degradation of the personality. 7 Contra-indications to the operative intervention: massive adhesive processes; multiple wounds (fraction); processes in the vital sections of the brain. COMBINED CCT The combined trauma - simultaneous injury by one kind of mechanical energy of two or more anatomical-topographical systems (craniovertebral, cranio-transabdominal). Multiple trauma - simultaneous injury by one kind of damaging energy of one body, or several bodies of one system (multiple contusions of the brain, multiple fractures of the lower extremity). The combined affection - injury of the organism by various damaging factors working simultaneously (mechanical, thermal, radial energy). Classification: damages of the facial skeleton damages of the thorax and respiratory organs damages of the abdominal cavity damages of the spine and spinal cord cranial damages Classification of combined CCT by a degree of severity: severe CCT and severe extracranial (shock in 70 %) severe CCT and not severe extracranial (shock in 14-15 %) not severe CCT and severe extracranial (shock in 40-50 %) not severe CCT and not severe extracranial (shock in 4-5 %) The leading part in development of shock in CCT is played by an extracranial pathology. The shock in isolated CCT develops in: multiple injures of the bones of the arch and the basis of the skull (of type) multiple injures of soft tissues of the head (of hemorrhagic type) in children (any haematomas can cause a hypovolemic shock) 8 Difference of shock from damages of the brain stem. If there is a decrease of hemodynamics, disturbances of breath and stem (floating eyeballs, anisocoria, ChaineStocks respiration) it should be attributed to CCT. Isolated CCT has shock in 1-1.5 % of cases. In mild CCT there is an amplification of function of the hypophysis (secretion of СТH grows), promoting the prompt formation of an osseous callous. And in severe CCT function of the hypophysis is suppressed. Facial damages: single fracture of the jaw traumatic extraction of a tooth injures of soft tissues, without a severe bleeding Лефор 2, 3 multiple damages of the facial skeleton Thoracic damages fracture of the clavicle fracture up to 3 ribs without damage of the organs of the chest, nerves and vessels fracture of ribs with damage of the vessels damage of the organs of the chest hemo-pneumothorax damage of the organs of the mediastinum Transabdominal damages subserous rupture of the gut any damages of hollow and parenchymatous organs Vertebral damages fracture of bodies, arches, but without damage of the spinal cord and roots fracture of bodies, arches with damage of the spinal cord or roots Damages of the locomotor system: the closed single fracture of the forearm, shin fracture of the pelvis, hip, open fractures, multiple fractures of bones, tearing off of the 9 feet FATTY EMBOLISM Fatty embolism is characterized by sudden, quick onset (hemiparesis or a plegia, disturbances of consciousness, narrow pupils). In LP - liquor is pure or hemorrhagic. On the 2nd-3rd day there is fat in urine. Typically haematoma has a gradual onset. Fatty microthrombembolism occurs more often in the diencephalic areas. Differential diagnostics of fatty embolism and intracranial haematoma Intracranial haematoma Fatty embolism Severity of a craniocerebral trauma characteristic severe CCT the combined damages and CCT are usually a little milder Severity of the combined damages various usually severe Disturbance of consciousness gradual aggravation of a degree of sudden sharp disturbance of consciousness disturbance of consciousness Pyramidal symptoms gradual increase are sharply expressed at once. If there is no pyramidal manifestation, diencephalic and mesencephalic signs develop (paresis of the look, narrowing of pupils, floating eyeballs) Eye fundus vessels are dilated spasm of the arteries, haemorrhages, veins are fragmented Echoencephalography displacement of the M - echo There is no displacement of the median structures Lumbar puncture 10 the increased pressure, blood in transparent or xanthochromatic liquor Diagnostic mill apertures Haematoma Nothing is defined R-graphy of the lungs There is no thing The lung with "snow" petechial rash on a lateral surface of the stomach, fat in urine on the 2nd-3rd day For the prevention of development of fatty embolism in patients with the combined trauma it is necessary to administer the preparations having immediate effect: rheologic properties of blood Lipin, Lipostabil, Essentiale antagonists of calcium (Verapamil, Nifedipine) to increase ОЦК (10 % NaCl 100 ml + 100 ml Rheopolyglucin) ГОМК, Nootropics, Difenin transfusion of liquids under the control of intracranial pressure (the control of blood osmolarity: if osmolarity is normal - intracranial pressure is normal too, if osmolarity of plasmas is reduced - intracranial pressure is always increased). It implies, that in the first 2-3 days it is better to administer osmodiuretics, and then saluretics. Carrying out of functionally stable osteosynthesis (plates, a spoke, but not a nail): the first 4-6 hours – in mild or moderate CCT without disturbances (shock) on removing from a shock - in mild or moderate CCT and a shock accompanying it after stabilization of vital functions – in severe CCT with vital disorders If fatty embolism has developed, it is necessary to influence development of collateral vessel. Transfusion of liquids under the control of intracranial pressure (the control of blood osmolarity: if osmolarity is normal - intracranial pressure is normal too, if osmolarity of plasma is reduced - intracranial pressure is always increased). Antagonists of calcium 11 increase of resistency of the brain tissue to hypoxia The Signay-cocktail - is introduced once a day intravenously 500 ml of 20 % Mannitol 50 mg Dexasone (Metipred) 500 mg of vitamin Е 500 mg Difenine preparations increasing elasticity of vessels (Trentalum, Theonicol) in the acute the period solutions Lipostabil, Inhibitors of proteases, Essentiale Ether intramuscularly Control questions: 1.

He did not lose consciousness. There was bleeding from a wound in the left parietal area. He was brought 14 to a neurosurgical hospital. On examination: a lacerated-contused, moderately bleeding wound in the left parietal area, hemiparesis on the right. It is necessary to make the preliminary diagnosis, to define the plan of examination and treatment. The answer: the preliminary diagnosis - the open penetrating pressed-in fracture in the left parietal area. The plan of examination – craniograms in two projections, echoencephalography. The plan of treatment –establishment of the pressed-in fracture, a decompression of the brain. № 2. The brick has fallen to the head of the patient 32 ages. There was a short-term loss of consciousness. The wound in the frontal area was treated by iodine, the aseptic bandage was applied. In the evening the condition of the patient and headache worsened, there was, vomitting, weakness in the left extremities. On examination: anisocoria D is more than S, a moderate hemiparesis on the left, in the posterior parts of the frontal area on the right, parasacrally, a contused wound of 2,5 cm; on X-ray images – the pressed-in fracture in this area. What is preliminary diagnosis and what tactics should be applied on examination and treatment of this patient? The answer: the preliminary diagnosis is the open penetrating pressed-in fracture in the posterior part of the frontal area on the right. Medical tactics will consist in carrying out primary surgical treatment of the wound, elimination of the pressed-in penetrating fracture of the arch of the skull with administration of the anti-inflammatory therapy directed at the prevention of early and late purulent processes. № 3. During hunting the victim has received a gunshot wound. The entrance aperture was moderate bleeding, located in the right temporal area. Was at the moment of examination the patient on conscious. Anisocoria D is more than S. Make the preliminary diagnosis and defines methods of diagnostics and the treatments indicated to this patient. The answer: the preliminary diagnosis is open gunshot injury of the skull and brain of the right temporal area. It is necessary to make craniograms, CT-scan - study. Medical tactics – to make primary surgical treatment of the entrance aperture with the subsequent administration of anti-inflammatory and dehydration therapy. № 4. The patient was brought to the special traumatological department in the condition of alcoholic intoxication. Psychomotor excitation was marked. In the area of the left temple the ecchymosis is revealed, bloody fluid discharged from the external acoustic meatus on the left. The diagnosis is alcoholic intoxication. Treatment was administered. In 15 6 hours after admission the patient had an attack of tonic spasms, the anisocoria (the left pupil was more than right), a condition of deep sopor developed. Estimate the condition of the patient; specify the plan of examination and treatment. What tactical mistake has been made in establishing the diagnosis? The answer: the condition of the patient is extremely severe with a syndrome of dislocation and wedge of the brain stem in the big aperture of stem structures of the brain. The plan of examination – a craniography, CT-scan - study. According to vital indications urgent operation is indicated decompressive cranial trepanation in the left frontal-temporal area, removal of haematoma. The tactical mistake was, that liquorrhoea from the left was underestimated ear, as a symptom of fracture of the basis and the arch of the skull (middle cranial fossa) and probability of development of intracranial traumatic haemorrhage that has not been taken into account on primary examination of the patient because of his alcoholic intoxication. 6.2 Materials of methodological maintenance of the basic stage of the class.
