ABSTRACT Background Studies on non‐extubation after elective pediatric neurosurgery are limited. As can contribute to adverse patient outcomes, there is a need understand this problem better. We aimed assess the incidence, risk factors, and impact of in operating room (OR) neurosurgery.

Abstract Moyamoya disease demonstrates angiographically enlarged anterior falcine artery (AFA) participating in anastomotic dural–pial collateralization along parasagittal locations. It is conceivable that vasospasm following subarachnoid hemorrhage (SAH-V), this AFA may responsively enlarge to perfuse ischemic parenchyma. We investigate the angiographic attributes of and its reactive functions post-SAH-V. A retrospective assessment clinical imaging data was done on patients with SAH...

Scalp block or local anesthetic infiltration for craniotomy blunts hemodynamic response to noxious stimuli, reduces opioid requirement and decreases postoperative pain. Analgesia Nociception Index (ANI) provides objective information about the magnitude of pain (rated from 0 100 with indicating extreme nociception absence nociception) adequacy intra-operative analgesia. This study compared fentanyl consumption guided by ANI in patients who receive scalp those incision-site craniotomy.Sixty...

Background: Cervical spine movement during intubation with direct laryngoscopy can predispose to new-onset neurological deficits in patients cervical instability. While fiberoptic-guided (FGI) is mostly preferred such patients, this not always possible. Videolaryngoscopy results less than and may be an alternative FGI The objective of study was compare awake those McGrath videolaryngoscope-guided (VGI) undergoing surgery for Methods: Forty-six adult upper instability scheduled stabilization...

BACKGROUND: Cerebral vasospasm can complicate aneurysmal subarachnoid hemorrhage (aSAH), contributing to cerebral ischemia. We explored the role of remote ischemic preconditioning (RIPC) in reducing and ischemia improving outcomes after aSAH. MATERIALS AND METHODS: Patients with ruptured aneurysm undergoing surgical clipping meeting trial criteria were randomized true RIPC ( n = 13) (inflating upper extremity blood pressure cuff thrice 30 mmHg above systolic for 5 min) or sham 12) ethical...

Abstract Background and Purpose Presurgical prediction of H3K27M mutation in diffuse midline gliomas (DMGs) on MRI is desirable. The purpose this study to elaborate conventional (cMRI) features H3K27M‐mutant DMGs identify that could discriminate them from wild‐type (WT) DMGs. Methods CMRI 123 patients with DMG were evaluated conforming the institutional research protocols. Multimodality was performed 1.5 or 3.0 Tesla MR Scanners imaging protocol, including T1‐weighted (w), T2w,...

Analgesia Nociception Index (ANI) and Surgical Pleth (SPI) are measures of nociception-antinociception balance during general anaesthesia. The validity these two monitors autonomic changes brought about by intraoperative blood loss noradrenaline infusion has not been studied earlier. primary objective the study was to determine effect bleeding on ANI SPI. secondary observe SPI correlation between SPI.In this prospective observational study, 43 patients undergoing surgery for excision a...

Noxious stimulation such as skull pin insertion for craniotomy elicits a significant hemodynamic response. Both regional analgesic techniques (pin-site infiltration [PSI] and scalp block [SB]), systemic strategies (opioids, alpha-2 agonists, anesthetics, beta-blockers) have shown to attenuate this Analgesia Nociception Index (ANI) provides objective information about the magnitude of nociception adequacy analgesia. This study compared ANI changes in patients receiving local anesthetic SB...

Direct laryngoscopy and tracheal intubation is a noxious stimulation that induces significant stress response. Currently, this nociceptive response assessed mainly by haemodynamic changes. Recently, analgesia nociception index (ANI) introduced into anaesthesia practice provides objective information about parasympathetic (low stress) sympathetic (high balance, which reflects the degree of intraoperative nociception/analgesia. This study evaluated changes in ANI haemodynamics during...

Anaesthesia information management system (AIMS) is increasingly implemented in many hospitals. Considering the capital cost involved its installation and maintenance, it important to evaluate performance adoptability by end users. This study assessed completeness of manual data recording AIMS one year after implementation also evaluated potential predictors for completeness.In this retrospective audit AIMS, 1000 electronic anaesthesia records patients undergoing neurosurgical procedures...

A safe airway technique minimizes intubation-associated cervical-spine movement and consequent neurological injury in patients with unstable cervical spine (UCS). Awake fiberoptic-guided intubation (FGI) is preferred UCS. Alternatively, intubating laryngeal mask assisted (ILMA-AI) can be performed both during elective emergency, requires less expertise cost-effective. This study evaluated FGI ILMA-AI UCS.This was a parallel-group randomized controlled trial at tertiary neurosciences...

Decompressive craniectomy (DC) is a life-saving intervention for malignant cerebral venous thrombosis (CVT). Earlier studies have shown increase in oxygenation after DC traumatic brain injury but similar are lacking CVT. We hypothesized that regional (tissue) oxygen saturation (rSO2) on the side of CVT lower than contralateral and improves DC.In this prospective cohort study, rSO2 was monitored using near-infrared spectroscopy technique, before both hemispheres. Data regarding factors likely...
