Filter by:The PRICE study primarily aims to identify predictors of early extubation following elective infratentorial craniotomy in adults. It also aims to (i) measure the rate of early extubation in different clinical settings; and (ii) study how the decision to extubate early is made and communicated in clinical practice. The first phase of the study (PRICE1) is a brief online survey addressed to physicians in charge of neurosurgical patients (neuroanesthesiologists, neurosurgeons, neurocritical care specialists) in multiple countries.
Pain in patients undergoing posterior fossa surgery is regarded as more intense when compared to pain in patients undergoing supratentorial cranial surgeries. It may result in a rise in blood pressure and heart rate leading to serious effects as increased intracranial pressure and intracranial hemorrhage. For a long time, the control of pain has been the role of opioids. However, the use of opioids is not devoid of side effects. Hence, combining other techniques as partial scalp block with general anesthesia may be beneficial in controlling hemodynamics and decreasing the amount of opioids used without sacrificing the good quality of analgesia and anesthesia.
Medulloblastoma is a rapidly-growing tumor of the cerebellum, this area controls balance, posture and sophisticated motor functions like finer hand movements, speech, and swallowing. It has been reported that those children fall frequently so the purpose of this study is to investigate the effectiveness of balance and coordination training in these Children.
The aim of this study is to evaluate the changes of cerebral oxygen saturation during hyperventilation and normo-ventilation (using near-infrared spectroscopy) in pediatrics undergoing posterior fossa tumor resection.
The purpose of this study is to create a rehabilitation program for children who survived posterior fossa tumors using the latest technology. Supposed that training in Fitlight, Dynavision D2, NeuroTracker will improve executive functions, visual-motor integration, fine and gross motor functions.
Surgery within the posterior fossa is associated with the highest incidence and greatest severity of acute postoperative pain that may persist beyond the immediate postoperative period. The utilization of local nerve blocks of the scalp in children may provide analgesia with stable hemodynamics while reducing the need for other anesthetics such as inhaled anesthetics and opioids. This could in turn result in less side effects, higher patient and family satisfaction, and better outcomes. The use of ultrasound-guided greater occipital nerve block (GONB) for perioperative pain management of posterior fossa surgery in pediatrics is not previously reported.
Post-operative paediatric cerebellar mutism syndrome (pCMS) is a well-recognised complication of resective surgery for brain tumours of the cerebellum and fourth ventricle in children. Occurring in around 25% of infratentorial craniotomies, it is characterised by a delayed onset of mutism and emotional lability, and may comprise motoric and cognitive cerebellar deficits. Transient mutism gives way to prolonged, and often incomplete, recovery. Neuroimaging studies are beginning to reveal anatomical and functional aberrancies in the brain of children with pCMS. The cerebellar efferent pathways are likely to be implicated as a neuroanatomical substrate in the development of pCMS, as shown by a handful of diffusion tractography studies to date. However, the pathophysiology of this condition still remains unclear. Hypoperfusion of supratentorial cortical and subcortical structures may mediate the speech and behavioural deficits seen in pCMS, and is a candidate for a causal pathophysiological mechanism. This study aims to prospectively image children with pCMS using advanced MRI techniques including diffusion tractography and arterial spin labelling, and to correlate this with clinical descriptions of the syndrome. All children referred to Great Ormond Street Hospital for Children with a posterior fossa brain tumour will be imaged pre-operatively, post-operatively and at delayed follow-up. In tandem with this, clinical assessments will be made of children post-operatively to ascertain which patients develop pCMS. In addition, anonymised advanced MRI data on healthy controls will be used as a comparator group.
This study evaluate the effects of scalp block versus local infiltration on haemodynamic response to head pin replacement and skin incision and postoperative analgesia in posterior fossa surgery
