View clinical trials related to Supratentorial Brain Tumor.
Filter by:Supratentorial craniotomy is one of the most common neurosurgical procedures, with severe perioperative pain. Inadequate perioperative pain relief has been associated with increased blood pressure and intracranial pressure, favoring bleeding and cerebral cerebral hypoperfusion. The ideal analgesia for neurosurgery requires complete pain relief, eliminates the side effects of opioid drugs and no influence for neurological function. Previous studies have proposed a multimodal analgesic strategy, combining analgesics and local anaesthesia, it is expected to achieve the above benefits.
The goal of this clinical trial is to learn about in patients with supratentorial brain tumours. The main questions it aims to answer is: Can short-term preoperative walking exercise protect cognitive function in the short term after craniotomy in patients with supratentorial brain tumor and reduce the incidence of surgery-related complications? Participants will be asked to receive general care and regular walking exercises prior to surgery. Researchers will compare patients who receive only general care before surgery to see if preoperative walking exercise has an effect on postoperative prognosis.
Neurosurgical operations are characterised by major fluid shift, frequent use of diuretics, and prolonged operative time. The role of fluid therapy in these patients is very critical; hypovolemia might decrease cerebral perfusion; while, fluid over-infusion might swell the brain (1-3). Thus, fluid management in these procedures complex and challenging. Evidence on the optimum protocol for intraoperative fluid management in neurosurgical patients is still lacking. Adequate intracranial volume management is considered a key factor that would overcome the tumour bulk and the surrounding vasogenic oedema facilitating surgical access . Thus, a relaxed brain is one of the targets of intraoperative fluid management during craniotomy. The slack brain would allow proper surgical retraction and consequently, reduces brain retractor ischemia. Brain relaxation scale (BRS) had shown a good correlation with intracranial pressure thus, an increasing interest was paid to BRS as a simple surrogate for intracranial pressure (4-8). Goal-directed hemodynamic therapy (GDT) in the operating room is a term used to describe the use of defined hemodynamic targets to guide intravenous fluid and inotropic therapy. Pulse pressure variation (PPV) is one of the robust dynamic indices of fluid responsiveness which is based on heart-lung interactions (9-12). GDT had been frequently investigated in the operating room in high-risk patients especially in major surgery. However, the impact of GDT on patient outcomes, especially BRS, is not well evaluated in brain surgery (12-15). In this study, we evaluated PPV-guided fluid management compared to standard fluid management in patients undergoing supratentorial mass excision. We hypothesised that in these procedures, GDT might restrict intraoperative fluid volume, improve brain relaxation, and provide stable patient hemodynamics.
The PAINLESS study is a single-center, prospective, randomized, open-label, blinded-endpoint (PROBE) controlled clinical pilot study to compare the efficacy and safety of pre-emptive scalp infiltration with ropivacaine plus ketorolac and ropivacaine alone for postoperative pain relief in adults undergoing elective supratentorial craniotomies.
