Filter by:Patients with Supratentorial tumor undergoing craniotomy have a higher risk of postoperative pain, which will affect their postoperative quality of recovery (QoR). Although scalp nerve block (SNB) can alleviate postoperative pain, the effect on postoperative QoR in patients with supratentorial tumor undergoing craniotomy is still unclear. This study is aimed to explore the effect of SNB on postoperative QoR in this population. To explore the effect, we design a randomized controlled trial in which 84 patients with supratentorial tumor will be randomly assigned to either the SNB group or control group. The primary outcome is 15-item QoR score at 24 h after surgery. The secondary outcomes include 15-item QoR scores at 72 h after surgery, Riker Sedation-Agitation Scale, nausea and vomiting, intraoperative opioids and propofol consumption, perioperative heart rate and mean artery pressure, the duration of anesthesia and surgery, time to extubation, PACU duration, the length of postoperative days, adverse events within 72h and total medical expenses.
1. The primary aim of this study is to investigate the correlation between the length of ICU stay and a newly developed FIVE score in neuro-intensive care patients. 2. The secondary objectives are to evaluate the impact of the FIVE score on hospital length of stay, Modified Rankin Scale, and mortality, as well as to determine the correlation between the GCS, FOUR, and FIVE scores
This phase I trial tests the safety, side effects, and best dose of ex vivo expanded natural killer cells in treating patients with cancerous (malignant) tumors affecting the upper part of the brain (supratentorial) that have come back (recurrent) or that are growing, spreading, or getting worse (progressive). Natural killer (NK) cells are immune cells that recognize and get rid of abnormal cells in the body, including tumor cells and cells infected by viruses. NK cells have been shown to kill different types of cancer, including brain tumors in laboratory settings. Giving NK cells from unrelated donors who are screened for optimal cell qualities and determined to be safe and healthy may be effective in treating supratentorial malignant brain tumors in children and young adults.
Hemodynamic control during craniotomies can be a bit hectic specially during periods of intense noxious stimulation. For long anesthesiologists used high doses of opioids such as fentanyl and remifentanyl to provide analgesia with a good hemodynamic control during intraoperative period in patients undergoing craniotomies. However, the use of opioids was not devoid of side effects. Exploring other anesthetic plans using multiple opioid free anesthetic adjuvants that have analgesic effects given together in small doses appear to be appealing plan. This idea is the basis of our proposed study in which we compare the hemodynamic effects of using opioid free anesthesia versus opioid anesthesia in cranial surgeries.
Optional brain relaxation improves the surgeon's operating conditions and is likely to minimize the degree of retraction injury ,with the potential for providing patients with a better outcome. The choice of anesthetic drugs can affect intraoperative brain relaxation. Propofol suppresses brain metabolism, reduces cerebral blood flow, and provides satisfactory brain relaxation. Desflurane is often criticized in neurosurgery due to its cerebral vasodilation and potential to increase intracranial pressure, however, it has been found to have a little clinical significance. This study intends to compare the effects of desflurane with propofol on brain relaxation in patients with supratentorial tumors under mild hyperventilation, and to provide new clinical evidence for the use of desflurane in neurosurgical anesthesia.
There is no clear consensus among neuroanesthesiologists regarding which anesthetic regimen is optimal for craniotomy. Propofol and short-acting opioids (such as remifentanil, fentanyl, or sufentanil) are commonly used. However, use of opioids is associated with increased risk of respiratory depression and postoperative nausea and vomiting. Dexmedetomidine is a highly selective α2-adrenoreceptor agonist that has been considered as a useful and safe adjunct to anesthesia for various surgical procedures
Compared with MRI or CT, brain biological electrical impedance tomography were performed on patients with supratentorial tumors and healthy people . The AUC (area under the curve) of ROC, which is associated with the increased maximum and the difference between left and right equilibrium of impedance value, is calculated. The specificity of brain biological electrical impedance tomography in screening supratentorial tumors are evaluated. To compare the changes of parameters detected by brain biological electrical impedance tomography, the enrolled brain tumor patients with cerebral edema were paired with themselves and intravenous infusion of mannitol so that the sensitivity of this device in monitoring cerebral edema can be evaluated.
Study was designed to evaluate optimal timing for selective scalp block in patients undergoing general anesthesia for supratentorial craniotomy.Pain score assessed by visual analog scale (VAS) preoperatively (baseline) and after extubation at 2, 6, 12 and 24 hours; time first request of a patient for rescue analgesia; intraoperative anesthetics and opioids consumption; awakening time; perioperative complications.
We aim to determine the level of intraoperative PEEP that optimizes lung compliance without causing a rise in subdural pressure and if we can utilize optic nerve sheath diameter measurement as an indicator for ICP while optimizing lung compliance during supratentorial tumor surgeries.
Hyperosmotic agents are used to decrease intracranial pressure. The aim of the study is to compare the effects of continuous 3% hypertonic saline (HS), bolus HS and 20% mannitol on intraoperative brain relaxation in patients with raised intracranial pressure during surgery for supratentorial tumors.
