Abstract
Purpose The study aims to evaluate the role of substance P in cerebral edema and outcomes associated with acute TBI. Method Patients with acute TBI who presented within 6 h and a CT scan showed predominantly cerebral edema were included in the study. Substance P level was assessed from a serum sample collected within 6 h of trauma. We also evaluated the brain-specific gravity using the Brain View software. Result A total of 160 (128 male) patients were recruited. The median serum substance P concentration was 167.89 (IQR: 101.09-238.2). Substance P concentration was high in the early hours after trauma (p = 0.001). The median specific gravity of the entire brain was 1.04. Patients with a low Glasgow coma scale (GCS) at admission had a high concentration of the substance P. In the univariate analysis, low GCS, elevated serum concentrations of substance P level, high Rotterdam grade, high cerebral edema grade, a high international normalized ratio value, and high blood sugar levels were associated with poor outcomes at six months. In logistic regression analysis, low GCS at admission, high cerebral edema grade, and elevated blood sugar level were strongly associated with poor outcomes at six months. The area under the receiver operating characteristic curve was 0.884 (0.826-0.941). Conclusion Serum substance P is strongly associated with the severity of cerebral edema after TBI. However, brain-specific gravity does not directly correlate with posttraumatic cerebral edema severity. Serum substance P does not influence the clinical outcome of traumatic brain injury.

Abstract
Background and Aims The autonomic nervous system (ANS) is cardinal for systemic homeostasis. Autonomic dysfunction is prevalent in as high as 65% of patients presenting for cardiac surgery in the Indian scenario. Pre-existing cardiac autonomic dysfunction (CAD) in surgical patients can accentuate perioperative haemodynamic fluctuations during stressful intraoperative events, predispose to adverse cardiac events, and contribute to morbidity and mortality. The prevalence and predictors of CAD in the elective neurosurgical population are unknown in the Indian scenario. The current study was conducted to bridge this knowledge gap. Methods In this single-centre prospective observational study conducted at a tertiary care neurosciences centre, among 400 consenting adult patients of either gender, between 18 and 80 years of age, undergoing elective neurosurgery, the preoperative ANS function at the bedside was assessed as the primary outcome measure. The ANS status was evaluated using ANSiscope™-derived indices of heart rate variability. The diagnosis of CAD was made when the ANS index exceeded a threshold of 13.5. Data regarding predictors of CAD were collected from patient records as the secondary outcome measure. Statistical analysis was done using the R software. A P-value of <0.05 was considered statistically significant. Results The prevalence of preoperative CAD in our study population was 79.7% (319/400 patients). None of the demographic and baseline clinical characteristics we studied predicted CAD in our study. Conclusion We observed a significant prevalence of preoperative CAD among elective neurosurgical patients. None of the parameters we evaluated predicted CAD in our study.

Abstract
BACKGROUND Transcranial sonographic (TCS) evaluation of optic nerve sheath diameter (ONSD), third ventricular diameter (TVD) and mean flow velocities (Vm) and pulsatility index (PI) of middle cerebral artery (MCA) can provide important insights to the change in intracranial dynamics following ventriculo-peritoneal (VP) shunt surgery. The primary objective of this study was to observe changes in ONSD values following VP shunt at 12 h, compared to pre-VP shunt values. METHODS After obtaining ethical approval, patients admitted with a diagnosis of hydrocephalus posted for a VP shunt surgery were prospectively enrolled. TCS evaluation was done before induction of anesthesia and 12-hour post-VP shunt surgery. We recorded the values of ONSD, TVD and Vm and PI MCA at both time points. RESULTS Thirty-four patients (19 male) were evaluated for ONSD and for the improvement of symptoms. Transtemporal window could not be obtained in six patients. At 12 h following VP shunt, bilateral median ONSD values reduced significantly from their pre-VP shunt values [right ONSD- 0.62 (0.59-0.64) to 0.53 (0.5-0.54) mm (p < 0.001); left ONSD- 0.62 (0.59-0.63) to 0.53 (0.5-0.54) mm (p < 0.001)]. Similarly, the median TVD at 12 h post-VP shunt reduced significantly from its pre-VP shunt measurements [0.97 (0.85-1.09) to 0.74 (0.7-0.84) cm]. PI MCA values reduced significantly, while Vm MCA values increased significantly from the pre-VP shunt values. CONCLUSION VP shunt reduced the ONSD, TVD, PI MCA and increased the Vm MCA after shunt surgery as early as 12hrs.

Abstract
BACKGROUND Patients in the neurointensive care unit (NICU) fail extubation despite successful weaning from mechanical ventilation. Parameters currently used in the general intensive care unit do not accurately predict extubation success in the NICU. In this study, peak cough expiratory flow rate, ultrasound-based diaphragm function assessment, and comprehensive clinical scoring systems were measured to determine whether these new variables, in isolation or combination, could predict extubation failure successfully in the NICU. METHODS All adult patients extubated after 48 h of mechanical ventilation in the NICU of a single tertiary care center were recruited into the prospective cohort. The patient's cough peak expiratory flow rate (C-PEFR), diaphragm function, and clinical scores were measured before extubation. C-PEFR was measured using a hand-held spirometer, diaphragm function (excursion, thickness fraction, and diaphragm contraction velocity on coughing) was assessed using ultrasound, and the clinical scores included the visual pursuit, swallowing, age, Glasgow Coma Scale for extubation (VISAGE) and respiratory insufficiency scale-intubated (RIS-i) scores. The patients requiring reintubation within 48 h were considered as extubation failure. Univariate and multivariate logistic regression analyses were done to identify predictors of extubation failure. RESULTS Of the 193 patients screened, 43 were recruited, and 15 had extubation failure (20.9%). Patients with extubation failure had higher RIS-i scores (p < 0.001) and lower VISAGE scores (p = 0.043). The C-PEFR and diaphragm function (excursions and contraction velocity on coughing) were lower in patients with extubation failure but not statistically significant. The variables with p < 0.2 in univariate analysis (RIS-i, VISAGE, and diaphragm cough velocity) were subjected to multivariate regression analysis. RIS-I score remained an independent predictor (odds ratio 3.691, 95% confidence interval 1.5-8.67, p = 0.004). In a receiver operating characteristic analysis, the area under the curve for RIS-i was 0.963. An RIS-i score of 2 or more had 94% specificity and 89% sensitivity for predicting extubation failure. CONCLUSIONS The RIS-i score predicts extubation failure in NICU patients. The addition of ultrasound-based diaphragm measurements to the RIS-i score to improve prediction accuracy needs further study.

Abstract
OBJECTIVES Modified ECT is routinely conducted using face mask (FM) and bag ventilation technique. Trans-nasal Humidified Rapid Insufflation Ventilatory Exchange (THRIVE) is a novel hands-free insufflation technique that provides oxygenation and prolongs apnoea time. There is limited literature comparing the two techniques. Primary objective of this study was to compare oxygen desaturation between THRIVE and FM techniques during ECT while secondary objective was to compare hemodynamics and complications. METHODS Patients aged 18-50 years undergoing 3rd-5th ECT treatments were enrolled. First ECT was with FM technique followed by THRIVE (with LUBO collar) in the next ECT. Except for the oxygenation technique, the protocol for ECT administration was similar with both techniques. SpO2 values were recorded every minute for 10 min while hemodynamic parameters were measured at 2 min and 5 min following administration of electrical stimulus. Any drop in SpO2 below 92 % was considered as a desaturation event. RESULTS A total of 201 patients underwent ECTs, one each with FM and THRIVE technique. Median age of patients was 28 years. There was no difference in SpO2 between the techniques (main effect P = 0.324, interaction P = 0.14). Only one patient had desaturation with THRIVE requiring intervention with FM. None of the patients had any airway complications in terms of nasal injury, hoarseness, or pneumothorax with THRIVE. CONCLUSION THRIVE is a safe alternative option for hands-free oxygenation while administering ECT. However, considering patient safety, an anaesthesiologist competent in airway management must be readily available.

Abstract
PURPOSE Accurate assessment of dural sinus, deep and cortical venous thrombosis on MR imaging is challenging. The aim of this study is to evaluate the accuracy of 3D-T1 turbo spin echo (T1S), sequences in detecting venous thrombosis and comparing it with susceptibility-weighted imaging (SWI), magnetic resonance venography (MRV) and post contrast T1 magnetization-prepared rapid acquisition gradient echo (T1C). METHODS A blinded retrospective observational analysis of 71 consecutive patients evaluated for cerebral venous thrombosis (CVT) and 30 control patients was performed. Multimodality reference standard adopted included T1C, SWI with MRV. Sub-analyses in superficial, deep and cortical venous segments were performed in addition to correlation of signal intensity of thrombus with the clinical stage. RESULTS A total of 2222 segments in 101 complete MRI examinations were evaluated. Sensitivity/specificity/positive predictive value/negative predictive value/accuracy and precision of T1S for detection of cortical vein thrombosis was 0.994/1/1/0.967/0.995/1, 1/0.874/0.949/1/0.963/0.950 for detection of superficial venous sinus thrombosis and 1/1/1/1/1/1 for deep venous thrombosis. The AUC yield for T1S was 0.997 for cortical, 1 for deep and 0.988 for superficial venous segments. CONCLUSION T1S paralleled the accuracy of conventional sequences in the overall detection of CVT but showed superior accuracy in the detection of cortical venous thrombosis. It makes a fitting addition to the CVT MRI protocol in scenarios demanding negation of gadolinium administration.

Abstract
INTRODUCTION Analgesia Nociception Index (ANI) as a monitor of peri-operative nociception-anti-nociception balance has not been studied in paediatric neurosurgery. The objectives were to study the correlation between ANI (Mdoloris Education system) and revised FLACC (r-FLACC) score for the prediction of acute postoperative pain in paediatric population undergoing elective craniotomies and to compare the changes in ANI values with heart rate (HR), mean arterial pressure (MAP) and surgical plethysmographic index (SPI) during various time points of intraoperative noxious stimulation and before and after opioid administration. METHODS This prospective observational pilot study included 14 patients between 2 and 12 years of age undergoing elective craniotomies. HR, MAP, SPI, ANI instantaneous (ANIi) and ANI mean (ANIm) values were recorded intraoperatively and before and after opioid administration. Postoperatively HR, MAP, ANIi and ANIm, and pain scores (r-FLACC scale) were recorded. RESULTS There was a statistically significant negative correlation between ANIi and ANIm with r-FLACC during the time course of PACU stay (r = - 0.89, p < 0.001 and r = - 0.88 and p < 0.001 respectively). Intraoperatively, in patients with ANIi values < 50, with additional fentanyl administration, there was an increasing trend in values beyond 50, which was statistically significant (p < 0.05) at 3, 4, 5 and 10 min. The trend in changes of SPI after opioid administration was not found to be significant for patients irrespective of the baseline SPI values. CONCLUSION The ANI is a reliable tool for objective assessment of acute postoperative pain as assessed by r-FLACC in children undergoing craniotomies for intracranial lesions. It may be used as a guide to nociception-antinociception balance during the peri-operative period in this population.

Abstract
INTRODUCTION Post-operative delirium (POD) is a major complication after anesthesia and surgery with an incidence varying from 5 to 50%. The incidence of POD after intracranial surgery is likely to be higher due to the pre-existing brain pathology and direct handling of the brain during neurosurgery. The primary objective of this study was to assess the incidence of POD after intracranial neurosurgery and our secondary objective was to identify the potential risk factors for its occurrence. MATERIALS AND METHODS This prospective observational study was conducted after the institutional ethics committee approval between october 2020 and march 2021. We included patients of either gender aged ≥ 18 years and undergoing elective intracranial neurosurgery. Exclusion criteria included patients aged below 18 years, undergoing emergency neurosurgery, patients with impaired consciousness and patients with psychiatric comorbidities or those taking psychotropic medications. We planned to exclude patients from analysis who were transferred to intensive care unit (ICU) or if they were not extubated after surgery. Our study outcome was development of POD as assessed by confusion assessment method (CAM). RESULTS The overall incidence of POD during the three postoperative days was 19.2% (n=60/313). The incidence of POD on days 1, 2, and 3 were 19.2% (n=60/313), 17.2% (n=50/291), and 16.3% (n=39/239). Preoperative delirium and hyperactive Emergence Delirium were found to be the significant predictors of POD. CONCLUSION Every one in five patients undergoing intracranial neurosurgery is vulnerable for the development of POD within first three days after surgery. The incidence of occurrence of POD is time-sensitive and is decremental.

Abstract
Background and Aims Patients with traumatic brain injury (TBI) frequently require emergency surgery. There is a paucity of literature with regard to anesthetic requirements in these patients. The aim of the study was to compare the dose of propofol required for induction of anesthesia in patients with different grades of TBI. Material and Methods This prospective, observational study included patients with mild, moderate, and severe grades of TBI undergoing emergency surgery within 48 h of injury. Bispectral Index (BIS) values were recorded using a bilateral BIS sensor. Anesthesia was induced with a target controlled infusion (TCI) pump. Once BIS reached 40, plasma (Cp) and effect-site (Ce) concentration and total dose of propofol required were noted from the TCI pump. Results Of the 96 patients recruited, 27, 36, and 33 patients belonged to mild, moderate, and severe TBI (sTBI) groups, respectively. The Ce of propofol in mild, moderate, and sTBI groups was 6 ± 0.9, 5.82 ± 0.98, and 4.48 ± 1.5 μg/mL (P < 0.001), and the dose of propofol required was 1.9 ± 0.2, 1.8 ± 0.4, 1.41 ± 0.5 mg/kg, respectively (P < 0.001). Baseline BIS on the injured side was 80 ± 7.8, 71 ± 9.4, 55 ± 11.6, and on the uninjured side was 89 ± 5.5, 81 ± 8.4, and 65 ± 12 in mild, moderate, and sTBI groups, respectively. Conclusions The requirement of propofol was reduced in patients with sTBI. The dose of propofol required for induction of anesthesia as determined using Ce was significantly lower only between sTBI and mild TBI and not between patients with sTBI and moderate TBI or between mild and moderate head injury. BIS values were significantly different between the groups (highest in mild TBI and lowest in sTBI) and between normal and injured sides within each group.

Abstract
BACKGROUND Delayed neurocognitive recovery (DNR) is commonly seen in patients in the postoperative period. Literature has shown that monitoring cerebral desaturation intraoperatively can predict the development of DNR in elderly patients undergoing surgery in prone position. This prospective observational study was conducted in patients of all ages, with the primary objective to determine the incidence of DNR and its correlation with cerebral oximetry. The secondary objectives were to determine if intraoperative cerebral desaturation influenced the neuropsychometric variables from preoperative to postoperative period. METHODS This study included 61 patients, aged > 18 years undergoing spinal surgery in prone position. An evening before surgery and at 48 h postoperatively, patients were subjected to neuropsychological examination; Hindi Mental State Examination, Colour Trail Test 1 (CTT 1), CTT 2, Auditory Verbal Learning (AVLT) tests conducted by principal investigator (PI). DNR was defined as a 20% change in any of the test scores from the baseline. rSO2 was recorded bilaterally every 10 min throughout surgery by an independent person. Cerebral desaturation was defined as a 20% drop in rSO2 from the control value. RESULTS The incidence of DNR was 24.6%. The duration of anesthesia and cerebral desaturation were found to be independently predictive of DNR, with each hour of anesthesia causing a two-fold increase in the chances of development DNR (P = 0.019) and presence of cerebral desaturation causing a 6-fold increase (P = 0.039). CTT 1 and CTT 2 tests had significantly larger increase in test scores in the postoperative period, in patients with cerebral desaturation. CONCLUSION Duration of anesthesia and cerebral desaturation were factors predictive of the development of DNR in patients undergoing spine surgery in prone position.

Abstract
Background and Aims Surgical Pleth Index (SPI) provides an objective assessment of nociception - anti-nociception balance but is influenced by multiple confounders. The effect of change of position on SPI, has not been studied extensively. The aim of the study was to observe the effect of prone positioning on SPI and its correlation with hemodynamic variables, in patients undergoing lumbar and thoracic spine surgery. Material and Methods This prospective observational pilot study included 14 patients. In addition to hemodynamic monitoring, SPI, entropy and pulse pressure variability (PPV) were monitored. Propofol and Fentanyl infusions were used for maintenance of anesthesia. The patients were made prone on bolsters and all the variables were recorded every 5 minutes in supine position and after making prone for 20 minutes, before and after incision, muscle splitting and laminectomy. Results Comparing the last value of the variables in the supine position with those immediately after making prone, SPI increased by 16.36 units (P = 0.003), followed by gradual reduction over the next 20 minutes. Mean arterial pressure and heart rate increased transiently (Pvalue = 0.028 and 0.025, respectively) without any significant change in PPV. Surgical incision also led to a significant increase in SPI. Conclusion Prone positioning leads to significant increase in SPI, probably due to increased sympathetic tone.

Abstract
OBJECTIVE The role of nimodipine and milrinone in the management of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (SAH) was studied using clinical and TCD (transcranial Doppler) parameters. METHODS In this prospective observational study, patients with DCI after aneurysmal SAH presenting between November 2020 and June 2021 who were treated by either intra-arterial nimodipine (IAN) or intravenous milrinone (IVM) were included after excluding patients in whom both IAN and IVM had been given or mechanical angioplasty was performed. Twelve-hourly TCD was performed during the course of the therapy. Clinical improvement and the development of new brain infarcts were also assessed. A P value <0.05 was considered statistically significant. RESULTS Thirty-four patients fulfilled the inclusion criteria (IVM, 13/34 [38%]; IAN, 21/34 [62%]); patients in the IVM group (vs. IAN group) had poorer median Glasgow Coma Scale score (12 vs. 13), poorer motor response (<M6 response, 5/13 [38%] vs. 5/21 [24%]; P = 0.36) and higher grades (modified Fisher grade ≥3) of SAH (12/13 [92%] vs. 8/21 [86%]; P = 0.56). More patients in the IAN group (vs. IVM group) showed clinical improvement (17/21 [81%] vs. 10/13 [77%]; P = 0.77), development of new infarcts (15/21 [71%] vs. 7/13 [54%]; P = 0.29] and discharged to home (13/21 [62%] vs. 6/13 [46%]; P = 0.36) with less mortality (1/21 [9%] vs. 4/13 [23%]; P = 0.037). On TCD analysis, both IAN and IVM protocols showed similar effects in middle cerebral artery vasospasm; however, IAN proved better over time. In group-effect analysis, the IAN protocol was significantly better in anterior cerebral artery and posterior cerebral artery vasospasm compared with IVM protocol. CONCLUSIONS In this single-center small study, patients in the IAN group had significantly less mortality compared with the IVM group in the management of DCI after aneurysmal SAH.

Abstract
AbstractThis observational study was conducted owing to the challenges of the positron emission tomography/magnetic resonance imaging (PET/MRI) that requires longer duration scanning of radiopharmaceutical injected patient and added MRI environment. The aim of this study was to assess radiation dose at different distances from the patient and the radiation burden to anesthesiologist and other personnel in performing PET/MRI under general anesthesia or sedation. First, the pre- and postscan whole body radiation exposure (WBE) from the patient were obtained for 45 minutes (n = 109) after injection of the radiopharmaceutical. The WBE was obtained at specific distances from brain (10, 30, and 100 cm) and abdomen (10 and 30cm) of patients undergoing F18 fluorodeoxyglucose PET/MRI brain or whole body studies. Second, WBE of the anesthesiologist and other staff working was separately measured using pocket dosimeters during the whole procedure. In brain scans, the mean absorbed dose rates (ADR) of prescan (45 minutes) and postscan (45 minutes) were 44.4 and 31.1 μSv at 10 cm, 14.9 and 9.7μSv at 30 cm, and 3.5 and 2.8 μSv at 100 cm, respectively, from surface of head. Similarly, it was 54.8 and 30.3 μSv at 10 cm, 23 and 13.6μSv at 30 cm, respectively, from surface of abdomen. In WB scans, the mean ADR was higher than the brain scans. Anesthesiologist exposure overall was found to be 4.84 µSv/patient/scan (112 patients). The anesthesiologist receives a safe mean effective dose in PET/MRI scanning. With good training and adequate planning, it is possible to decrease the radiation exposure to all the concerned personnel including anesthesiologists.

Abstract
Purpose
Hypotension during the early intraoperative phase is common and can lead to adverse perioperative outcomes. Fluid preloading is one of the methods to limit its occurrence. Patients with chronic compressive cervical myelopathy may have autonomic dysfunction, which can aggravate hemodynamic alterations during anesthesia. This study compared the occurrence of postinduction hypotension and changes in cardiac dynamic indices in patients with and without crystalloid preloading undergoing decompressive cervical spine surgery.
Methods
This randomized controlled trial was conducted over 15 months after obtaining patient consent, approval of the institute ethics committee, and trial registration. We compared preanesthetic fluid loading with Ringer's lactate (20 mL/kg over 30 minutes) with no preloading (2 mL/kg/h maintenance) in 60 consecutive patients undergoing cervical spine surgery. The ANSiscope was used to determine baseline cardiac autonomic function. Noninvasive cardiac output monitor was used to assess changes in heart rate, mean arterial pressure, cardiac index (CI), stroke volume variation (SVV), and total peripheral resistance index during study intervention, anesthetic induction, tracheal intubation, and change in position from supine to prone.
Results
The incidences of postinduction hypotension were 26.7% (8/30) and 86.7% (26/30) and the median doses of mephentermine used were 0 and 6 mg, respectively, in patients with and without fluid preloading (both
p
< 0.001). Preloading resulted in improvement in CI, reduction in SVV, and lesser vasopressor use.
Conclusion
Preloading reduced the occurrence of postinduction hypotension and vasopressor use, improved CI, and reduced SVV during the early intraoperative period.
Registration number of Clinical Trial
The trial was registered with Clinical Trial Registry of India (CTRI/2018/07/014970 on 19/07/2018).

Abstract
Background Hypotension is one of the most common complications following induction of general anesthesia. Preemptive diagnosis and correcting the hypovolemic status can reduce the incidence of post-induction hypotension. However, an association between preoperative volume status and severity of post-induction hypotension has not been established in neurosurgical patients. We hypothesized that preoperative ultrasonographic assessment of intravascular volume status can be used to predict post-induction hypotension in neurosurgical patients. Our study objective was to establish the relationship between pre-induction maximum inferior vena cava (IVC) diameter, collapsibility index (CI), and post-induction reduction in mean arterial blood pressure in neurosurgical patients. Materials and Methods A prospective observational study was conducted including 100 patients undergoing elective intracranial surgeries. IVC assessment was done before induction of general anesthesia. Receiver operating characteristic (ROC) curve analysis was used to determine the cutoff values of maximum and minimum IVC diameter (IVCDmax and IVCDmin, respectively) and CI for prediction of hypotension. Results Post-induction hypotension was observed in 41% patients. Patients with small IVCDmax and higher CI% developed hypotension. The areas under the ROC curve (AUCs) were 0.64 (0.53-0.75) for IVCDmax and 0.69 (0.59-0.80) for IVCDmin. The optimal cutoff values were1.38 cm for IVCDmax and 0.94 cm for IVCDmin. The AUC for CI was 0.65 (0.54-0.77) and the optimal cutoff value was 37.5%. Conclusion Pre-induction IVC assessment with ultrasound is a reliable method to predict post-induction hypotension resulting from hypovolemia in neurosurgical patients.

Abstract
Abstract
Background Patients with coronavirus disease 2019 (COVID-19) presenting for neurosurgery are not rare. Considering the lack of literature informing the outcomes in this subset, present study was conducted to compare perioperative management and postoperative outcomes between COVID-19 and non-COVID-19 neurosurgical patients.
Methods After ethics committee approval, data of all patients with COVID-19 along with an equal number of age and diagnosis matched non-COVID-19 patients undergoing neurosurgery between April 2020 and January 2021 was analyzed retrospectively. Predictors of poor outcome were identified using multivariate logistic regression analysis.
Results During the study period, 50 COVID-19 patients (28 laboratory confirmed (group-C) and 22 clinicoradiological diagnosed [group-CR]) underwent neurosurgery and were compared with 50 matched non-COVID-19 patients. Preoperatively, clinicoradiological diagnosed COVID-19 patients had higher American Society of Anesthesiologists (ASA) grade (p = 0.01), lower Glasgow Coma Scale (GCS) score (p < 0.001), and more pulmonary involvement (p = 0.004). The duration of intensive care unit stay was significantly longer in laboratory confirmed patients (p = 0.03). Poor clinical outcome (in-hospital mortality or discharge motor-GCS ≤ 5) did not differ significantly between the groups (p = 0.28). On univariate analysis, younger age, higher ASA grade, lower preoperative GCS, and motor-GCS, higher intraoperative blood and fluid administration and traumatic brain injury diagnosis were associated with poor outcome. On multivariable logistic regression. only lower preoperative motor-GCS remained the predictor of poor outcome.
Conclusions The concomitant presence of COVID-19 infection did not translate into poor outcome in patients undergoing neurosurgery. Preoperative motor-GCS predicted neurological outcome in both COVID-19 and non-COVID-19 neurosurgical patients.

Abstract
Background Delirium after surgery is a spectrum of clinical syndrome constituting emergence delirium (ED) and/or postoperative delirium (POD). Objectives The primary objective of this study was to evaluate the incidence of ED and POD in patients after neurosurgical procedures. The secondary objectives were to examine the relationship between ED and POD and identify perioperative risk factors of ED and POD. Materials and Methods This is a prospective cohort study conducted at the National Institute of Mental Health and Neurosciences. After obtaining the ethics committee approval, consecutive adult patients scheduled for elective neurosurgical procedures from February 2018 to November 2018 were included. We excluded children, patients with preoperative Glasgow Coma score <15, and patients with preoperative delirium. ED was assessed using Riker's Sedation-Agitation Score and POD was assessed using Confusion Assessment Method. Data collection included patient demographics, details of anesthetics and analgesics, and neurosurgical details. Results The incidence of ED and POD was 41% (N = 82/200) and 20% (N = 40/200), respectively. The occurrence of ED and POD coexisting as a continuous spectrum was 15%. Patients undergoing spine surgeries were found to have 44% less risk of ED than after cranial surgeries (P = 0.032). Presence of ED was associated with 1.8 times higher risk of POD (P < 0.001) and male gender was associated with 2.5 times higher risk of POD (P = 0.005). Conclusions Incidences of ED and POD are higher after neurosurgery as compared with that reported in nonneurosurgical population previously.

Abstract
BACKGROUND Severe traumatic brain injury (TBI) results in raised intracranial pressure (ICP). Ultrasonographic measurement of the optic nerve sheath diameter (ONSD) is a noninvasive method for the assessment of raised ICP. Manipulation of positive end-expiratory pressure (PEEP) and end-tidal carbon dioxide (ETCO2) are often used to optimize ICP and improve oxygenation in TBI patients. This study evaluated the effects of PEEP and ETCO2 on ONSD and regional cerebral oxygen saturation (rScO2) in patients with acute TBI. METHODS A total of 14 patients (11 males) aged older than 18 years with acute severe TBI were included in this study. ONSD and rScO2 were assessed before and after changes in PEEP from 5 to 10 cm H2O and in ETCO2 from 40 to 30 mm Hg on both pathologic and nonpathologic sides. RESULTS Increasing PEEP and reducing ETCO2 resulted in changes in ONSD and rScO2 on both pathologic and nonpathologic sides. On the pathologic side, ONSD and rScO2 were highest with a PEEP of 10 cm H2O:ETCO2 40 mm Hg combination and lowest with PEEP of 5 cm H2O:ETCO2 30 mm Hg (ONSD 5.24±0.49 vs. 4.27±0.36 mm, P<0.001; rScO2 70.7±9.91% vs. 66.3±9.75%, P<0.001); both PEEP and ETCO2 had significant effects on ONSD and rScO2 (P<0.001). On the nonpathologic side, ONSD and rScO2 were highest and lowest with PEEP of 10 cm H2O:ETCO2 40 mm Hg and PEEP of 5 cm H2O:ETCO2 30 mm Hg combinations, respectively (ONSD: 4.93±0.46 vs. 4.02±0.40 mm, P<0.001; rScO2: 74.77±8.30% vs. 70.69±8.12%, P<0.001). ETCO2 had a significant effect on rScO2 (P<0.001), but the impact of PEEP on rScO2 was not statistically significant (P=0.05). CONCLUSION Increasing PEEP resulted in significant increases in ONSD and rScO2, whereas reducing ETCO2 significantly decreased ONSD and rScO2.

Abstract
Backgroud and Aims: Conference presentations provide an opportunity to rapidly share findings of new research despite limitations of details and reach. Earlier studies have examined publication rates of conference presentations in anesthesia. However, conversion rate of neuroanesthesia meeting presentations to publications is unknown. We assessed the publication rate of neuroanesthesia conference presentations from India over a 5-year period and identified factors contributing to subsequent publications. Material and Methods: Conference abstracts of the Indian Society of Neuroanaesthesiology and Critical Care (ISNACC) from 2014 to 2018 were studied with regard to conversion to full-length publications. Details of presentations were obtained from abstracts published in the journal of ISNACC and details of publications were collected by searching Google and PubMed using title and author details. Results: Only 17.5% (40/229) of the abstracts presented at ISNACC conferences over a 5-year period resulted in subsequent full-text publications in peer-reviewed journals. Prospective cohort studies (OR [95% CI] 2.84 [1.05–8.56], P = 0.048), randomized trials (OR [95% CI] 2.69 [1.04 to 7.9], P = 0.053), and abstracts from public institutions (OR [95% CI] 3.44 [1.4 to 10.42], P = 0.014) were significantly associated with publications after conference presentations. Conclusion: The conversion rate of conference presentations of neuroanesthesia society of India into journal publications is significantly low. There is need for neuroanesthesia community of India to work together to improve the translation of presentations into publications.

Abstract
BACKGROUND Quality of health care is a major issue. Providing care that accommodates individual patient preferences and values is termed patient-centered care. OBJECTIVES In this study, we assessed family satisfaction (FS) with intensive care unit (ICU) care and family satisfaction with decision making in the care of critically ill neurological/neurosurgical patients. MATERIALS AND METHODS The FS-ICU questionnaire was used to assess family satisfaction. Data were analyzed using frequency tables and rates. RESULTS Of the 154 FS-ICU questionnaires analyzed, the overall satisfaction rate with care was 59.97, with information needs was 56.52, and with decision making was 59.46. Lower satisfaction rates among families may be due to the highly morbid nature of neurological illness in their kin or due to differences in socioeconomic factors. CONCLUSIONS Periodic audit of the FS questionnaire is useful in assessing the quality of health care in the neuro-ICU. Efforts to incorporate suggestions of study subjects may improve FS with patient care and decision making.

Abstract
Abstract
Purpose Plasma exchange is one of the recommended therapeutic procedures for autoimmune neurological conditions and involves removal of plasma over multiple sessions for exclusion of autoantibodies responsible for the disease process. This study aimed to evaluate the changes in the concentration of plasma constituents with five cycles of alternate day therapeutic plasma exchange (TPE), identify contributing factors for hypoproteinemia, and examine its impact on clinical outcomes.
Methods This was a single-center, retrospective cohort study involving patients with autoimmune neurological diseases who underwent at least five cycles of TPE in the neurointensive care unit (NICU). Data regarding plasma protein concentrations, serum electrolytes, fluid input/output before and after every TPE cycle and clinical outcomes in terms of duration of ventilation, and NICU and hospital stay were collected from the medical records over a 1-year period.
Results The levels of plasma proteins (total protein, albumin and globulin) (p < 0.001), sodium (p < 0.001), calcium (p < 0.001), and hemoglobin (p = 0.002) declined significantly after TPE. Difference in plasma protein levels before and after TPE did not correlate with durations of mechanical ventilation and hospital and NICU stay. Difference in total protein and globulin correlated negatively with fluid balance and positively with daily protein intake (p < 0.05 for both).
Conclusion A significant decrease in plasma proteins and other plasma constituents is seen with TPE. Changes in plasma proteins are related to hemodilution and protein intake. Decrease in plasma proteins did not affect duration of hospital or NICU stay and duration of mechanical ventilation.

Abstract
BACKGROUND AND PURPOSE Presurgical prediction of H3K27M mutation in diffuse midline gliomas (DMGs) on MRI is desirable. The purpose of this study is to elaborate conventional MRI (cMRI) features of H3K27M-mutant DMGs and identify features that could discriminate them from wild-type (WT) DMGs. METHODS CMRI features of 123 patients with DMG were evaluated conforming to the institutional research protocols. Multimodality MRI was performed on 1.5 or 3.0 Tesla MR Scanners with imaging protocol, including T1-weighted (w), T2w, fluid-attenuated inversion recovery, diffusion-weighted, susceptibility-weighted, and postcontrast T1w sequences. Pertinent cMRI features were annotated along the lines of Visually AcceSAble Rembrandt Images features, and Intra Tumoral Susceptibility Signal score (ITSS) was evaluated. R software was used for statistical analysis. RESULTS Sixty-one DMGs were H3K27M-mutant (mutant DMGs). The patients in the H3K27M-mutant DMG group were younger compared to the WT-DMG group (mean age 24.13 ± 13.13 years vs. 35.79±18.74 years) (p = 0.016). The two groups differed on five cMRI features--(1) enhancement quality (p = 0.032), (2) thickness of enhancing margin (p = 0.05), (3) proportion of edema (p = 0.002), (4) definition of noncontrast-enhancing tumor (NCET) margin (p = 0.001), and (5) cortical invasion (p = 0.037). The mutant DMGs showed greater enhancement and greater thickness of enhancing margin, while the WT DMGs exhibited significantly larger edema proportion with poorly defined NCET margins and cortical invasion. ITSS was not significantly different among the groups. CONCLUSION CMRI features like enhancement quality, the thickness of the enhancing margin, proportion of edema, definition of NCET margin, and cortical invasion can discriminate between the H3K27M-mutant and WT DMGs.

Abstract
BACKGROUND: Cerebral vasospasm can complicate aneurysmal subarachnoid hemorrhage (aSAH), contributing to cerebral ischemia. We explored the role of remote ischemic preconditioning (RIPC) in reducing cerebral vasospasm and ischemia and improving outcomes after aSAH. MATERIALS AND METHODS: Patients with ruptured cerebral aneurysm undergoing surgical clipping and meeting the trial criteria were randomized to true RIPC (n = 13) (inflating upper extremity blood pressure cuff thrice to 30 mmHg above systolic pressure for 5 min) or sham RIPC (n = 12) (inflating blood pressure cuff thrice to 30 mmHg for 5 min) after ethical approval. A blinded observer assessed outcome measures-cerebral vasospasm and biomarkers of cerebral ischemia. We also evaluated the feasibility and safety of RIPC in aSAH and Glasgow Outcome Scale-Extended (GOSE). RESULTS: Angiographic vasospasm was seen in 9/13 (69%) patients; 1/4 patients (25%) in true RIPC group, and 8/9 patients (89%) in sham RIPC group (P = 0.05). Vasospasm on transcranial Doppler study was diagnosed in 5/25 (20%) patients and 1/13 patients (7.7%) in true RIPC and 4/12 patients (33.3%) in sham RIPC group, (P = 0.16). There was no difference in S100B and neuron-specific enolase (NSE) levels over various time-points within groups (P = 0.32 and 0.49 for S100B, P = 0.66 and 0.17 for NSE in true and sham groups, respectively) and between groups (P = 0.56 for S100B and P = 0.31 for NSE). Higher GOSE scores were observed with true RIPC (P = 0.009) unlike sham RIPC (P = 0.847) over 6-month follow-up with significant between group difference (P = 0.003). No side effects were seen with RIPC. CONCLUSIONS: RIPC is feasible and safe in patients with aSAH and results in a lower incidence of vasospasm and better functional outcome.

Abstract
BACKGROUND The trial hypothesis was that, in a resource-constrained situation, short-course radiotherapy would improve treatment compliance compared with conventional chemoradiotherapy for locally advanced rectal cancer, without compromising oncological outcomes. METHODS In this open-label RCT, patients with cT3, cT4 or node-positive non-metastatic rectal cancer were allocated randomly to 5 × 5 Gy radiotherapy and two cycles of XELOX (arm A) or chemoradiotherapy with concurrent capecitabine (arm B), followed by total mesorectal excision in both arms. All patients received a further six cycles of adjuvant chemotherapy with the XELOX regimen. The primary endpoint was treatment compliance, defined as the ability to complete planned treatment, including neoadjuvant radiochemotherapy, surgery, and adjuvant chemotherapy to a dose of six cycles. RESULTS Of 162 allocated patients, 140 were eligible for analysis: 69 in arm A and 71 in arm B. Compliance with planned treatment (primary endpoint) was greater in arm A (63 versus 41 per cent; P = 0.005). The incidence of acute toxicities of neoadjuvant therapy was similar (haematological: 28 versus 32 per cent, P = 0.533; gastrointestinal: 14 versus 21 per cent, P = 0.305; grade III-IV: 2 versus 4 per cent, P = 1.000). Delays in radiotherapy were less common in arm A (9 versus 45 per cent; P < 0.001), and overall times for completion of neoadjuvant treatment were shorter (P < 0.001). The rates of R0 resection (87 versus 90 per cent; P = 0.554), sphincter preservation (32 versus 35 per cent; P = 0.708), pathological complete response (12 versus 10 per cent; P = 0.740), and overall tumour downstaging (75 versus 75 per cent; P = 0.920) were similar. Downstaging of the primary tumour (ypT) was more common in arm A (P = 0.044). There was no difference in postoperative complications between trial arms (P = 0.838). CONCLUSION Reduced treatment delays and a higher rate of compliance were observed with treatment for short-course radiotherapy with consolidation chemotherapy, with no difference in early oncological surgical outcomes. In time- and resource-constrained rectal cancer units in developing countries, short-course radiotherapy should be the standard of care.

Abstract
Introduction: Stroke is an omnipresent health problem that causes impairments in multiple domains and often leads to serious long-lasting consequences like pathological gait patterns. Gait rehabilitation is an important criterion for improvement in functionality. Body Weight Supported Treadmill Training (BWSTT) is being used as a method of gait rehabilitation, but efficiency of this method beyond traditional training is lacking evidence. Aim: To evaluate the effect of body weight supported treadmill training on gait recovery, lower limb function and dynamic balance in chronic stroke patients. Materials and Methods: A randomised controlled trial conducted in the Department of Neurorehabilitation of a specialty hospital, on 30 ambulatory chronic stroke patients having post stroke duration of six months or more. Study subjects were randomised into two groups. Group A received BWSTT with conventional rehabilitation for four weeks. Group B received only conventional rehabilitation for four weeks. Duration of conventional rehabilitation was 40 minutes in each group. Along with that group A received 20 minutes BWSTT and group B received 20 minutes of conventional gait training. Therapy was given three days a week. Assessment tools were Timed Up and Go test (TUG), Cadence, 10 metre Walk Test and Berg Balance Scale (BBS). The paired t-test was used for intragroup analysis and the unpaired t-test was used for intergroup analysis. Results: Total of 30 patients were registered in the study with mean age (years) 52.07±3.6736 and 52.40±3.906 for group A and group B, respectively. There was significant improvement in all outcome measures, e.g., BBS, TUG, 10 metre walk test and Cadence, in both the groups, pre and post intervention, but group A showed statistically significant improvement in parameters like dynamic balance, walking speed, and postural control and walking function (p<0.05). Conclusion: The BWSTT offers improvement in gait, in terms of walking speed, dynamic balance, posture control, that is significantly more than that of conventional gait training, as found in this study. The BWSTT might be included as a part of stroke rehabilitation program. Further multicentre studies with larger samples can throw more light on the intensity, dosage and methods of using BWSTT.

Abstract
Introduction The optimal time to discontinue patients from mechanical ventilation is critical as premature discontinuation as well as delayed weaning can result in complications. The literature on diaphragm function assessment during the weaning process in the intriguing subpopulation of critically ill neuromuscular disease patients is lacking. Methods Patients with neuromuscular diseases, on mechanical ventilation for more than 7 days, and who were ready for weaning were studied. During multiple T-piece trials over days, diaphragm function using ultrasound and diaphragm electrical activity (Edi peaks using NAVA catheter) was measured every 30 min till a successful 2 h weaning. Results A total of 18 patients were screened for eligibility over 5-month period and eight patients fulfilled the inclusion criteria. Sixty-three data points in these 8 subjects were available for analysis. A successful breathing trial was predicted by Edi reduction (1.22 μV for every 30 min increase in weaning duration; 0.69 μV for every day of weaning) and increase in diaphragm excursion (2.81 mm for every 30 min increase in weaning duration; 2.18 mm for every day of weaning). Conclusion The Edi and diaphragm excursion changes can be used as additional objective tools in the decision-making of the weaning trials in neuromuscular disease.

Abstract
INTRODUCTION Bicompartmental Supra plus Infratentorial Extra Dural Hematoma (SIEDH) is an uncommon yet important category of Extradural Hematoma (EDH) straddling the transverse sinus. It requires quick decision making and proper surgical evacuation. METHODS We did a retrospective chart review of all SIEDH cases from prospectively maintained operative database in our institute between 2011 & 2017. Clinical status at discharge and follow up were used to assess outcome. Ordinal regression analysis was used for analysis of factors predicting the outcome. We also describe the surgical procedure we follow at our high-volume trauma center for this unique entity. RESULTS We had 61 operated cases of SIEDH in our series. The median age of the cohort was 30 years (IQR: 21.5-42). Road Traffic Accident was the most common mode of injury (67.2 %). Median pre-operative GCS was 12 (IQR: 9-12). The median volume of SIEDH was 50cc (IQR: 40-70). Mass effect on 4thventricle and brainstem was seen in 47 and 34 patients respectively. An associated fracture was seen in 54 patients. Sinus injury related bleed was noted intra-operatively in 57 % (N = 35). Follow up was available for 60 cases with a median of 130 days. On evaluating with ordinal regression analysis, we found that, the GCS at presentation, pupillary asymmetry, volume of SIEDH, infratentorial volume, blood loss and mass effect on 4thventricle were statistically significant factors affecting GCS at discharge. However, the GCS at presentation, infratentorial volume and blood loss were the only factors determining GOS at follow-up. CONCLUSION SIEDH are uncommon yet important type of injury type which requires prompt attention and appropriate nuanced approach. Large SIEDH are commonly associated with sinus injury, and large volume blood loss may be anticipated. In addition, SIEDH may be associated with other traumatic brain injuries which may require surgical evacuation.

Abstract
BACKGROUND Abnormal hematologic parameters associated with unfavorable neurological outcomes in traumatic brain injury (TBI) have been studied in isolation. We aimed to study whether there are any additional parameters that improve standard prognostic models in TBI. METHODS This prospective observational study conducted in a tertiary neurological care center included adult patients with moderate and severe isolated head injury. Laboratory and clinical parameters were noted at admission, and the Glasgow Outcome Score-Extended of patients was assessed after 6 months. Multiple logistic regression was conducted using fixed coefficients of IMPACT (International Mission for Prognosis and Analysis of Clinical Trials) and CRASH (Corticosteroid Randomisation After Significant Head Injury) prognostic models. The new composite models were compared with the original models. RESULTS The study comprised 96 patients. Parameters with relatively good predictability for mortality were elevated international normalized ratio (area under the curve [AUC] 0.69, odds ratio 13.2), total leukocyte count (AUC 0.68, odds ratio 1.15), and transfusion of blood products (AUC 0.72, odds ratio 6.43). Addition of these led to a statistically small improvement in predictions of IMPACT and CRASH. Neutrophil-to-lymphocyte ratio was not a good predictor of mortality or morbidity (AUC 0.58 and 0.47, respectively). CONCLUSIONS International normalized ratio, total leukocyte count, and blood transfusion were found to be predictors of mortality and unfavorable neurological outcome in TBI at 6 months. Their addition to the IMPACT and CRASH prognostic models resulted in a modest improvement in the prediction of outcome in TBI.

Abstract
Abstract
Background Cranial surgery is associated with multiple postoperative complications varying from simple nausea and vomiting to devastating complications such as stroke and death. This multicentre collaborative effort was envisioned to collect observational data regarding postoperative complications in cranial surgeries among the Indian population. The aim of this study was to describe the postoperative neurological complications occurring within the first 24 hours after surgery and to identify the predictive factors.
Methods Data was collected from three participating tertiary care academic institutions. The study was prospective, observational, multicentre design with data collected over a period of two months or 100 cases, whichever is earlier, from each participating institute. A predesigned Microsoft excel sheet was distributed among all three centers to maintain uniformity. All patients aged 18 years and above of both sexes undergoing elective or emergency craniotomies were included in the study. The postoperative neurological complications (within 24 hours) assessed were: (1) Neurological deficit (ND) defined as new focal neurological motor deficit relative to preoperative status. (2) Sensorium deterioration (SD) defined as reduction in Glasgow coma score (GCS) by 2 or more points compared with preoperative GCS. (4) Postoperative seizures (SZs) defined as any seizure activity. All possible variables associated with the above neurological complications were tested using Chi-square/Fisher exact test or Mann–Whitney U test. The predictors, which were statistically significant at p < 0.2, were entered into a multiple logistic regression model. Alpha error of 5% was taken as significant.
Results Data from three institutions was collected with a total of 279 cases. In total, there were 53 (19%) neurological complications. There were 28 patients with new postoperative NDs (10.04%), 24 patients had SD (8.6%), and 17 patients had seizures (6.1%). Neurological deficits were significantly less in institution 2. Diagnosis of traumatic brain injury (TBI) was associated with very low risk of ND, and vascular pathology was associated with higher chance of a ND. The duration of anesthesia was found to be significantly predictive of SD (OR/CI = 1.01 / 1–1.02). None of the factors were predictive of PS.
Conclusion The incidences of postoperative ND, SD and postoperative seizures were 10%, 8.6%, and 6.1%, respectively. Studies with a much larger sample size are required for a better and detailed analysis of these complications.

Abstract
BACKGROUND AND PURPOSE Microcystic meningiomas (MM) are a distinctive, rare subtype of Grade I meningiomas with limited radiological descriptions. We intend to identify unique imaging phenotypes and seek radiopathological correlations. METHODS Retrospective analysis of histopathologically proven MM was undertaken. Clinicodemographic profiles, imaging, and histopathological characteristics were recorded. Spearman rank correlations among radiological and pathological attributes were performed. RESULTS Twenty-eight cases were analyzed (mean age = 45.5 years; M:F = 1:1.54; mean volume = 50.1 mL; supratentorial n = 27). Most lesions were markedly T2 hyperintense (higher than peritumoral brain edema-a unique finding) (89.3%) and showed invariable diffusion restriction, severe peritumoral brain edema (edema index >2 in 64.3%), a "storiform" pattern on T2-weighted images (T2WI) (75%), reticular pattern on postcontrast T1 (78.6%)/diffusion-weighted images (DWI) (65.4%), hyperperfusion, T1 hypointensity (84.6%), and absence of blooming on susceptibility-weighted image (80.9%). Storiform/reticular morphology correlated with large cysts on histopathology (ρ = .56; P = .005753). Lesion dimension positively correlated with reticular morphology on imaging (ρ = .59; P = .001173), higher flow voids (ρ = .65; P = .00027), and greater microcystic changes on histopathology (ρ = .51; P = .006778). Peritumoral brain edema was higher for lesions demonstrating greater angiomatous component (ρ = .46; P = .014451). CONCLUSIONS We have elucidated varied neuroimaging features and highlighted pathological substrates of crucial imaging findings of MM. MM ought to be considered as an imaging possibility in an extra-axial lesion with a marked hypodensity on noncontrast computed tomography, markedly T2-hyperintense/T1-hypointense signal, and a storiform/reticular pattern on T2W/GdT1w//DWI.
