    CLINICAL ARTICLE J Neurosurg 134:1631–1639, 2021 Preoperative factors associated with adverse events during awake craniotomy: analysis of 609 consecutive cases Hirokazu Takami, MD, PhD, Nikki Khoshnood, and Mark Bernstein, MD, MHSc, FRCSC Division of Neurosurgery, Toronto Western Hospital, Toronto, Ontario, Canada OBJECTIVE Awake surgery is becoming more standard and widely practiced for neurosurgical cases, including but not limited to brain tumors. The optimal selection of patients who can tolerate awake surgery remains a challenge. The authors performed an updated cohort study, with particular attention to preoperative clinical and imaging characteristics that may have an impact on the viability of awake craniotomy in individual patients. METHODS The authors conducted a single-institution cohort study of 609 awake craniotomies performed in 562 pa- tients. All craniotomies were performed by the same surgeon at Toronto Western Hospital during the period from 2006 to 2018. Analyses of preoperative clinical and imaging characteristics that may have an impact on the viability of awake craniotomy in individual patients were performed. RESULTS Twenty-one patients were recorded as having experienced intraoperative adverse events necessitating deeper sedation, which made the surgery no longer “awake.” In 2 of these patients, conversion to general anesthesia was performed. The adverse events included emotional intolerance of awake surgery (n = 13), air embolism (n = 3), gen- eralized seizure (n = 4), and unexpected subarachnoid hemorrhage (n = 1). Preoperative cognitive decline, dysphasia, and low performance status, as indicated by the Karnofsky Performance Status (KPS) score, were significantly associ- ated with emotional intolerance on univariate analysis. Only a preoperative KPS score < 70 was significantly associated with this event on multivariate analysis (p = 0.0057).

This includes excision of epileptogenic foci, (AEDs) performed in patients with medically refractory epilepsy. Approximately 2 million Americans with a diagnosis of epilepsy are treated with Antiepileptic Drugs , of these 20 percent continue to have seizures accounting for over 75 percent of epilepsy treatment cost in the United States. Surgical intervention can possibly eliminate epilepsy for patients’ refractory to medical treatment; however, only a small percentage of potential candidates are referred to epilepsy- Treatmentsurgery centers. of Epilepsy | www.smgebooks.com 1 Copyright Eloy JD.This book chapter is open access distributed under the Creative Commons Attribution 4.0 International License, which allows users to download, copy and build upon published articles even for commercial purposes, as long as the author and publisher are properly credited. Excision of epileptogenic foci can be performed under general anesthesia or by awake craniotomy, either with local anesthesia and sedation or in an asleep-awake-asleep technique. The anesthetic plan for surgery is largely influenced by the location of the seizure foci and intraoperative cortical mapping. Thesefoci may also be localized preoperatively using noninvasive studies such as MRI, PET and SPECT; however, video-EEG recording is the most important test to define a (EcoG) surgical target before surgery.

Hervey-Jumper, MD,1 Jing Li, MD,1 Darryl Lau, MD,1 Annette M. Molinaro, PhD,1 David W. Perry, PhD,2 Lingzhong Meng, MD,3 and Mitchel S. Berger, MD1 Departments of 1Neurological Surgery and 3Anesthesiology and Perioperative Care; and 2Surgical Neurophysiology, University of California, San Francisco, California OBJECT Awake craniotomy is currently a useful surgical approach to help identify and preserve functional areas during cortical and subcortical tumor resections. Methodologies have evolved over time to maximize patient safety and mini- mize morbidity using this technique. The goal of this study is to analyze a single surgeon’s experience and the evolving methodology of awake language and sensorimotor mapping for glioma surgery. METHODS The authors retrospectively studied patients undergoing awake brain tumor surgery between 1986 and 2014. Operations for the initial 248 patients (1986–1997) were completed at the University of Washington, and the subse- quent surgeries in 611 patients (1997–2014) were completed at the University of California, San Francisco. Perioperative risk factors and complications were assessed using the latter 611 cases. RESULTS The median patient age was 42 years (range 13–84 years). Sixty percent of patients had Karnofsky Perfor- mance Status (KPS) scores of 90–100, and 40% had KPS scores less than 80. Fifty-five percent of patients underwent surgery for high-grade gliomas, 42% for low-grade gliomas, 1% for metastatic lesions, and 2% for other lesions (corti- cal dysplasia, encephalitis, necrosis, abscess, and hemangioma).

The object of this study was to describe the experience of combining awake craniotomy techniques with high-field (1.5 T) intraoperative MRI (iMRI) for tumors adjacent to eloquent cortex. Methods. From a prospective database the authors obtained and evaluated the records of all patients who had undergone awake craniotomy procedures with cortical and subcortical mapping in the iMRI suite. The integration of these two modalities was assessed with respect to safety, operative times, workflow, extent of resection (EOR), and neurological outcome. Results. Between February 2010 and December 2011, 42 awake craniotomy procedures using iMRI were per- formed in 41 patients for the removal of intraaxial tumors. There were 31 left-sided and 11 right-sided tumors. In half of the cases (21 [50%] of 42), the patient was kept awake for both motor and speech mapping.

ABSTRACT The anesthesia for awake craniotomy (AC) is a consecrated anesthetic technique that has been perfected over the years. Initially used to map epileptic foci, it later became the standard technique for the removal of glial neoplasms in eloquent brain areas. We present an AC anesthesia technique consisting of three primordial times, called awake-asleep-awake, and their respective particularities, as well as delve into the anesthetic medications used. Its use in patients with low and high-grade gliomas was favorable for the resection of tumors within the functional boundaries of patients, with shorter hospital stay and lower direct costs. The present study aims to systematize the technique based on the experience of the largest philanthropic hospital in Latin America and discusses the most relevant aspects that have consolidated this technique as the most appropriate in the surgery of gliomas in eloquent areas. Keywords: Anesthesia. Craniotomy. Scalp. Glioma. Neurosurgery.
