Background Anesthetic agents used for awake craniotomy should be safe, short-acting, titratable, and provide an adequate level of sedation and analgesia, along with facilitating adequate neurological assessment during the functional testing. Our study aims to review the efficacy and safety profile, along with the potential for neurophysiological monitoring, of two commonly used anesthetic regimens, i.e., propofol and dexmedetomidine. Methods After the Ethics Committee approval, a retrospective analysis of 51 patients who underwent awake craniotomy for brain tumor excision over a period of 7 years was done. Those who received monitored anesthesia care (MAC) were divided into two groups, namely, Group P for that received propofol, and Group D that received dexmedetomidine and their hemodynamic profile, perioperative complications, neuromonitoring techniques, and postoperative course was noted from the records. Results A total of 31 patients were administered MAC with propofol and 20 with dexmedetomidine. The baseline demographic data, duration of surgery, intensive care unit (ICU), and hospital stay were comparable between the two. The hemodynamic profile as assessed by the heart rate and blood pressure was also comparable. The incidence of intraoperative seizures was found to be less in Group P, though. Episodes of transient desaturation were observed more in Group P (9.7%) than in Group D (5%), but none of the patients required conversion to general anesthesia. Direct cortical stimulation was satisfactorily elicited in 80% in Group P and 85% in Group D. Conclusions MAC with propofol and dexmedetomidine are acceptable techniques with comparable hemodynamic profile, intraoperative and postoperative complications, and potential for neurophysiological monitoring.

Background Various risk factors for tumors such as smoking, alcohol consumption, diet, and radiation, etc., were already identified. ABO blood group antigens are also present on epithelia, endothelia, and neurons. Recent evidence suggested the role of ABO antigens in the pathogenesis of certain malignancies. Materials and Methods A retrospective observational study was conducted in a tertiary care neurosurgical center in North India from January 2016 to December 2018. The hospital information system was used to obtain patient information while the blood center information system was used to collect blood group information. Brain tumors were majorly divided into cavernoma, glioma, meningioma, neuroma, pituitary adenoma, schwannoma, and others. Results We found a total of 1,970 patients with brain tumors admitted during our study period. Most patients had glioma (33.55%), followed by pituitary adenoma (20.05%) and neuroma (2.23%). B blood group individuals had more prevalence of cavernoma, glioma, meningioma, pituitary adenoma, schwannoma, and others followed by O, A, and AB. Only association of O blood group with neuroma tumor was found statistically significant. Conclusions Our patient population had blood group distribution similar to our general population and no significant association was observed by blood group antigens and brain tumors. Although neuroma was significantly associated with blood group O but the prevalence of neuroma in our patient population is very low hence large sample study is required to draw a firm conclusion regarding this association.

Abstract Pediatric Microcuff endotracheal tubes have come into vogue in the last few years. It overcomes the problems faced with the uncuffed or conventional cuffed tubes used in the pediatric population. In addition, the more distal placement of the polyurethane cuffs in these tubes eliminates the risk of airway mucosal injury and hence postoperative stridor. This makes it an attractive option for neurosurgical patients where there is a high incidence of cranial nerve deficit, airway edema, and the requirement of prolonged postoperative ventilation. But due to this particular design, Murphy's eye is not incorporated in the tube, which can potentially hamper ventilation, especially when used for long duration surgery. With the help of our case report, we would like to warn the readers regarding this life-threatening complication that resulted in hypoxia in a 1-year-old child in the postoperative period.

Abstract Background The determination of extubation (early or delayed) after pediatric craniotomy for intracranial tumor should be carefully considered because each has its pros and cons. The aim of this study was to investigate the incidence of the delayed extubation in these patients. The secondary goal was to identify the perioperative factors influencing the determination of delayed extubation. Methods This retrospective study was performed in pediatric patients with intracranial tumor who underwent craniotomy at a university hospital between April 2010 and March 2020. Preoperative and intraoperative variables were examined. The variables were compared between the delayed extubation and early extubation group. Results Forty-two of 286 pediatric patients were in the delayed extubation group with an incidence of 14.69%. According to multivariate analyses, the risk factors that prompted delayed extubation were the intracranial tumor size ≥ 55 mm (adjusted odds ratio [AOR], 2.338; 95% confidence interval [CI], 1.032–5.295; p = 0.042), estimated blood loss (EBL) ≥ 40% of calculated blood volume (AOR, 11.959; 95% CI, 3.457–41.377; p < 0.001), blood transfusion (AOR, 3.093; 95% CI, 1.069–8.951; p = 0.037), duration of surgery ≥ 300 minutes (AOR, 2.593; 95% CI, 1.099–6.120; p = 0.030), and completion of the operation after working hours (AOR, 13.832; 95% CI, 2.997–63.835; p = 0.001). Conclusions The incidence of delayed extubation after pediatric craniotomy was 14.69%. The predictive factors were the size of tumor ≥ 55 mm, EBL ≥ 40% of calculated blood volume, blood transfusion, duration of surgery ≥ 300 minutes, and completion of surgery after routine working hours.

Abstract Venous air embolism (VAE), though, clinically benign in majority of cases, the significant ones can lead to life-threatening cardiopulmonary and neurological consequences. Though studies mention the success rate of only 6 to 16% in aspirating air from the central venous catheter (CVC) during VAE, the technique is very specific for diagnosing VAE and has high therapeutic significance. We report a case in which delayed aspiration of air emboli from the CVC in suspected massive VAE during decompressive craniectomy resulted in rapid resolution of hemodynamic instability. If not inserted previously, CVC may be considered in a hemodynamically unstable patient with suspected VAE.

Abstract Background Meningioma brain tumor is associated with significant blood loss. Magnesium (Mg), a calcium blocker, can facilitate blood pressure control during surgery. This study aimed to evaluate effects of magnesium on blood loss, anesthetic requirement, and its neuroprotective effect in meningioma patients undergoing craniotomy. Methods Eighty patients aged between 18 and 70, American Society of Anesthesiologists physical status I and II, diagnosed with meningioma and scheduled for craniotomy tumor removal were randomized into two groups. Group M (Mg) received intravenous magnesium sulfate 40 mg/kg over 30 minutes initiated at skin incision and followed by continuous infusion of 10 mg/kg/h until dura closure. Group N (NSS) received 0.9% NaCl as placebo. Anesthesiologists in charge, surgeons, and patients were all blinded. The assessed outcomes were perioperative blood loss, anesthetic requirement, and pre- and postoperative neurocognitive functions assessed by Montreal Cognitive Assessment (MoCA). Results Thirty-eight patients in each group were analyzed. In group M, the intraoperative blood losses were 500 (70, 2300) mL, and 510 (100, 1600) mL in group N ( p = 0.315). Patients who received blood within 24 hours were 39.5% in group M and 47.4% in group N ( p = 0.644). No differences were observed in anesthetic requirement, intraoperative mean arterial pressure, hypotensive episodes, and vasopressor usages. There were no significant differences in postoperative MoCA score. Magnesium levels did not exceed acceptable levels. Conclusions Magnesium administration in meningioma patients had no significant effects on blood loss, anesthetic requirement, and postoperative cognitive function.

Background Organ transplantation reduces mortality and morbidity in patients with end-stage organ failure. The number of living organ donations is not enough to meet the current organ transplantation need; therefore, there is an urgent need for organ donation from cadavers. We aimed to determine the organ donation rates and reveal the obstacles against donation. Methods This study is designed as a retrospective multicenter study consisting of eight university hospitals, three training and research hospitals, 26 state hospitals, and 74 private hospitals in nine provinces in Turkey. A total of 1,998 patients diagnosed with brain death between January 2011 to April 2019 were examined through the electronic medical records data system. Results Median patient age was 38 (IQR: 19–57), and 1,275 (63.8%) patients were male. The median time between the intensive care unit admission and brain death diagnosis was 56 (IQR:2–131) hours. The most commonly used confirmatory diagnostic test was computed tomography in 216 (30.8%) patients, and the most common cause of brain death was intraparenchymal hemorrhage with 617 (30.9%) patients. A total of 1,646 (82.4%) families refused to permit organ donation. The most common reasons for refusal were family disagreement (68%), social/relative pressure (24%), and religious beliefs (8%). Conclusions Many families refuse permission for organ donation; some of the provinces included in this study experienced years of exceptionally high refusal rates.

Abstract The anesthetic management of a type-2 neurofibromatosis patient with a difficult airway is quite challenging. Such a situation tests the limits of the anesthesiologist's preparedness in maintaining the balance of the cerebral protection strategies and securing the airway. The anticipated challenges include managing the airway, controlling the raised intracranial pressure, and maintaining stable hemodynamics in anticipation of the expected blood loss. This article focuses on the preoperative airway evaluation and intraoperative preparedness in case of a patient with type-2 neurofibromatosis scheduled for craniotomy and excision of intracranial meningioma.

Intraoperative imaging is a ubiquitous tool in neurosurgery, cranial and spinal procedures. Mobius Airo TruCT (Shirley, Massachusetts, United States) is the largest inner bore, mobile intraoperative computed tomography (CT) imaging system that seamlessly integrates into an operating room (OR) setup. 1 In transport mode, the ring is aligned with the base, and the scanner moves on the ramp to the desired location for scanning of the operative site. An intraoperative imaging system that gives high-quality images and a wide fi eld of vision in both two- and three dimensions is provided by this device. There are few reports on use of intraoperative CT in neurosurgery and spine surgeries. 2 – 4 There is a paucity of literature on the ergonomics of CT scanner location, anesthetic workstation placement, and patient alignment for CT-guided neuronavigation, or scanning from an anesthesiologist point of view; we found it worthwhile to share our limited experience.

There are few reports on use of intraoperative CT in neurosurgery and spine surgeries. 2 – 4 There is a paucity of literature on the ergonomics of CT scanner location, anesthetic workstation placement, and patient alignment for CT-guided neuronavigation, or scanning from an anesthesiologist point of view; we found it worthwhile to share our limited experience.","PeriodicalId":16574,"journal":{"name":"Journal of Neuroanaesthesiology and Critical Care","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43394567","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}

Abstract The Bombay blood group is an extremely rare entity within the conventional ABO blood grouping system. End-stage liver disease also presents with myriad disorders of coagulation due to impaired synthesis and dysfunction of clotting factors, which predisposes patients to spontaneous and life-threatening episodes of bleeding. We report a patient with Bombay blood group and end-stage liver disease who presented to our hospital with a spontaneous subdural hematoma. Although conventional parameters of coagulation in this patient were abnormal, we were able to safely defer product transfusion because his thromboelastography (TEG) report was within acceptable ranges. In this article, we discuss our strategy for optimization of extremely limited blood resources in this scenario and perioperative strategies for the management of coagulation anomalies in patients with liver dysfunction.
