| Interventions |
Decompressive surgery (the following protocol is a consensus protocol that was worked out by Prof Unterberg (Department of Neurosurgery, University of Heidelberg) as a written paper and as a video and has been approved by all participating neurosurgeons): Decompressive surgery will consist of a large hemicraniectomy and a duraplasty. In summary, a large (reversed) question mark-shaped skin incision based at the ear will be made. A bone flap with a diameter of at least 12 cm (including the frontal, parietal, temporal and parts of the occipital squama) will be removed. Additional temporal bone will be removed so that the floor of the middle cerebral fossa can be explored. The dura will be opened and an augmented dural patch, consisting of either homologous periost and/or temporal fascia, or lyophylised cadaver dura, will be inserted. The dura will be fixed at the margin of the craniotomy to prevent epidural bleeding. The temporal muscle and the skin flap will then be re-approximated and secured. Infarcted brain tissue will not be resected. A sensor for registration of intracranial pressure may be inserted. In surviving patients, cranioplasty will be performed after at least 6 weeks, using the stored bone flap or an artificial bone flap. After surgery, patients will be transferred to the intensive care unit (ICU). The complete procedure is documented on video for post protocol analysis.
Conservative treatment: So far no mode of treatment of raised intracranial pressure has been proven to be superior to another. So treatment options listed here may vary from one institution to another. However, as much consistency of treatment between the centres as possible should be given. Therefore the following treatment modalities are given (the following protocol has been worked out by Dr Münch [Department of Anesthesiology and Intensive Care Medicine Mannheim, University of Heidelberg] and Dr Jüttler [Department of Neurology, University of Heidelberg] including the latest recommendations in neurological intensive care, stroke therapy and anesthesiological intensive care medicine and has been approved by all participating anesthesiological and neurological intensive care physicians): 1. Osmotherapy: osmotherapy should be started immediately after randomisation. The use of mannitol (i.e. Osmofundin 100 ml 15% solution 4 times per day) or glycerol (i.e. Glycerosteril 250 ml 10% solution, 4 times per day) is recommended. Dosage depends on serum osmolality and should reach 315 to 320 mOsm. 2. Intubation and mechanical ventilation: Patients will be intubated at a Glasgow Coma Score (GCS) lower than 8, or if there are any signs of respiratory insufficiency (pO2 <60 mmHg, pCO2 >48 mmHg), or if the airway is compromised. However, earlier intubation is left at the discretion of the treating physician. The same goes for ventilation mode. The following parameters should be reached: pO2 >75 mmHg, pCO2 36-44 mmHg. In case of raised intracranial pressure the ventilation mode is changed to a frequency of 35 and pO2 >100 mmHg. 3. Hyperventilation: The use of hyperventilation is discouraged in the early phase of treatment. In the case of further neurological deterioration and/or uncontrolled increase in intracranial pressure, hyperventilation may be started as ultima ratio. If hyperventilation is started, it is advised to monitor venous oxygenation with jugular bulb oxymetry and to maintain saturation higher than 50%. If venous oxygen saturation is not monitored, the pCO2 may be reduced to 28-32 mmHg. 4. Intracranial pressure (ICP) monitoring: The mode of invasive monitoring of the intracranial pressure is left at the discretion of the treating physician. If used, measurement should be performed in the ipsilateral side. 5. Sedation: The mode of sedation is left at the discretion of the treating physician. If sedation is required because of mechanical ventilation, further neurological deterioration, or uncontrolled increase of intracranial pressure, patients should be sedated with propofol. The use of barbiturates is discouraged because they may reduce cerebral perfusion pressure and often do not lead to sustained control of intracranial pressure. The use of muscle relaxants is left at the discretion of the treating physician. 6. Blood pressure control: blood pressure is controlled according to the latest recommendations of the treatment of acute ischemic stroke (Hacke et al. 2000). Recommended blood pressure in formerly hypertensive patients is 180/100-105 mmHg and in formerly normotensive patients 160-180/90-100 mmHg. The use of catecholamines or antihypertensive drugs is left at the discretion of the treating physician. An exception is made in patients receiving decompressive surgery. In these cases blood pressure during the postoperative phase of the first 8 hours after surgery is kept at 140-160 mmHg to avoid severe bleedings. 7. Positioning: elevation of the head 30 degrees 8. Body core temperature: normothermia should be reached. Therefore elevated body temperature is treated as soon as it exceeds 37.5 °C (Hacke et al. 2000). The use of antipyretics, external cooling or intravasal cooling is left at the discretion of the treating physician. 9. Blood glucose level: according to the latest recommendations of the treatment of acute ischemic stroke (Hacke et al. 2000) and recommendations of intensive care medicine (van den Berghe et al. 2001) blood glucose level should not exceed 140 mg/dl, 8 mmol/l, respectively. The parameter that should be reached is 80-110 mg/dl. Insulin should be used for control of blood glucose level. Hypoglycemia is treated with 10% or 20% glucose. 10. Hemoglobin concentration should be >10 g/dl (Hb >10 g/dl) 11. Prophylaxis of deep venous thrombosis is done with low-molecular-weight heparin (i.e. Fragmin once a day) All treatment on the ICU is documented for post protocol analysis. |
