Responses were obtained from various parts of the country. The majority of participants were practicing neuroanesthesiology. Questions asked were regarding clinical assessment, preoperative optimization, prognostication, and airway management in neurosurgery. More than 50% of practitioners acceded to most of the questions; however, the percentage of responses varied across different questions (50–100%).

The associated complex mechanisms involving biomechanics, markers, and neuroprotective drugs/measures have been extensively studied in preclinical studies with an ultimate aim to improve the patients' outcomes. Despite such efforts, only few have been successfully translated into clinical practice. In this review, we shall be discussing the major hurdles in the translation of preclinical results into clinical practice. The need is to choose an appropriate animal model, keeping in mind the species, age, and gender of the animal, choosing suitable outcome measures, ensuring quality of animal trials, and carrying out systematic review and meta-analysis of experimental studies before proceeding to human trials. The interdisciplinary collaboration between the preclinical and clinical scientists will help to design better, meaningful trials which might help a long way in successful translation. Although challenging at this stage, the advent of translational precision medicine will help the integration of mechanism-centric translational medicine and patient-centric precision medicine.","PeriodicalId":16574,"journal":{"name":"Journal of Neuroanaesthesiology and Critical Care","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44555042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case report describes the rare causation of perioperative hyperthermia in a patient presenting for epilepsy surgery. The patient had two episodes of hyperthermia, initially post-anesthetic induction and later in the immediate post-operative period. The quest for the etiology sheds light on a rare drug interaction between topiramate, an antiepileptic drug, and glycopyrrolate causing intraoperative hyperthermia. However, the literature has not reported drug interaction between topiramate and glycopyrrolate resulting in perioperative hyperthermia. The combination of a glycopyrrolate-induced rise in temperature and oligohidrosis could have resulted in hyperthermia in our patient. Thus, it is prudent to avoid glycopyrrolate in the perioperative period when patients are on topiramate.","PeriodicalId":16574,"journal":{"name":"Journal of Neuroanaesthesiology and Critical Care","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43750588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our patient underwent clipping of a ruptured anterior-communicating artery aneurysm. After the temporary clip applications on the right and left, A1 arterial segments led to a transient drop of somatosensory evoked potentials (SSEPs). At the same time, the frontal four-channel processed EEG showed a burst suppression (BS) pattern. Blood pressure augmentation and the removal of temporary clips helped restore the SSEP back to baseline and the disappearance of the BS pattern in processed EEG.

Antiepileptics are notorious for causing TEN.2 A 63-year-old female was admitted to the neurosurgical emergency department with recent onset, intermittent, focal seizures involving the right upper limb.

She underwent elective craniotomy and tumor decompression under general anesthesia with an uneventful intraoperative course. On postoperative day 1, the patient developed one episode of generalized tonic–clonic seizure followed by deterioration of sensorium. She was shifted to the neurosurgical intensive care unit (NSICU), intubated, and mechanically ventilated. On arrival to the NSICU, diffuse erythemawas noted involving the face, trunk, and extremities with oralmucosal involvement. The possibility of adverse drug reaction was considered, and all the possible medications (antibiotics, analgesics, and phenytoin) were withheld, and the patient was treated with intravenous hydrocortisone. A reviewofhistory fromclose relatives revealeda similar event in the past (5 years before) following consumption of oral phenytoin tablets. Onpostoperative day 2 inNSICU, the skin rashes becameveryprominentwith the appearanceofblisters all over the body followed by skin peeling (►Fig. 1A,B) and oozing of fluids.
