A Global Review of the Perioperative Care of Patients With Aneurysmal Subarachnoid Hemorrhage Undergoing Microsurgical Repair of Ruptured Intracerebral Aneurysm.

INTRODUCTION: To describe the perioperative care of patients with aneurysmal subarachnoid hemorrhage (aSAH) who undergo microsurgical repair of a ruptured intracerebral aneurysm. METHODS: An English language survey examined 138 areas of the perioperative care of patients with aSAH. Reported practices were categorized as those reported by <20%, 21% to 40%, 41% to 60%, 61% to 80%, and 81% to 100% of participating hospitals. Data were stratified by Worldbank country income level (high-income or low/middle-income). Variation between country-income groups and between countries was presented as an intracluster correlation coefficient (ICC) and 95% confidence interval (CI). RESULTS: Forty-eight hospitals representing 14 countries participated in the survey (response rate 64%); 33 (69%) hospitals admitted ≥60 aSAH patients per year. Clinical practices reported by 81 to 100% of the hospitals included placement of an arterial catheter, preinduction blood type/cross match, use of neuromuscular blockade during induction of general anesthesia, delivering 6 to 8 mL/kg tidal volume, and checking hemoglobin and electrolyte panels. Reported use of intraoperative neurophysiological monitoring was 25% (41% in high-income and 10% in low/middle-income countries), with variation between Worldbank country-income group (ICC 0.15, 95% CI 0.02-2.76) and between countries (ICC 0.44, 95% CI 0.00-0.68). The use of induced hypothermia for neuroprotection was low (2%). Before aneurysm securement, variable in blood pressure targets was reported; systolic blood pressure 90 to 120 mm Hg (30%), 90 to 140 mm Hg (21%), and 90 to 160 mmHg (5%). Induced hypertension during temporary clipping was reported by 37% of hospitals (37% each in high and low/middle-income countries). CONCLUSIONS: This global survey identifies differences in reported practices during the perioperative management of patients with aSAH.

A Nationwide Survey on the Practice of End-of-life Care Issues in Critical Care Units in India.

Background: End-of-life (EOL) care is the care of terminally ill patients who are nearing their end. It includes important components like palliative care, supportive care, hospice care, patient's right to choose, and choice of medical intervention, including continuation of routine medical interventions. The aim of this survey was to assess the practices of EOL care in various critical care units in India. Methods: The participants included clinicians involved in EOL care of patients with advanced diseases in different hospital across India. We sent blast emails and posted links on social media for inviting participants to take the survey. Study data were collected and managed by using Google Forms. The collected information was automatically entered into a spread sheet and stored in a secure database. Results: In total, 91 clinicians took the survey. The years of experience, practice area, and setting had significant effect on the palliative care, terminal strategy, and prognostication in terminally ill patients (p < 0.05). Statistical analysis was done using software STATA. Descriptive statistics were performed, and results were presented as number (percentage). Conclusion: The years of work experience, the practice area, and the practice setting have a strong impact on EOL care management of terminally ill patients. There are a lot of gaps in providing EOL care for these patients. Many reforms are needed in the Indian health care system to make EOL care better.

Effect of Percutaneous Tracheostomy on Optic Nerve Sheath Diameter [TONS Trial].

BACKGROUND: Elective percutaneous tracheostomy [PCT] is the widely performed procedure in neurocritically ill patients as an airway management choice in neurocritical care unit [NICU]. Intracranial pressure [ICP] is a vital parameter to be monitored in these patients while undergoing any surgical procedure including PCT. Optic nerve sheath diameter [ONSD], being a surrogate of ICP, can be done bedside and carries less complications than invasive ICP monitoring. The aim of our study was to assess the effect of PCT on ONSD at different stages of PCT. MATERIALS AND METHODS: A total of 158 patients with various intracranial pathologies scheduled for PCT in NICU were screened for eligibility in our study. We assessed mean values of ONSD, HR, MBP, and SpO2 for changes over various time points during PCT using generalized estimating equation (GEE). A p value of <0.05 was considered significant. RESULTS: A total of 135 patients who underwent PCT were analyzed for the study. The values of ONSD changed significantly at different stages of PCT procedure compared to baseline. The baseline ONSD value was 0.39 ± 0.05 cm. ONSD rose significantly to 0.40 ± 0.06 cm during positioning, 0.41 ± 0.06 cm during skin incision, 0.42 ± 0.07 cm during dilatation of tract, 0.41 ± 0.07 cm during insertion of tracheostomy, and 0.41 ± 0.06 cm at the end of the procedure. CONCLUSIONS: PCT leads to a significant rise of ONSD values during all stages of PCT. The available evidences point toward detrimental rise in ICP during PCT. ICP can be monitored noninvasively by measuring ONSD using bedside ultrasound. HOW TO CITE THIS ARTICLE: Kapoor I, Wanchoo J, Mahajan C, Singhal V, Roy H, Kumar S, et al.

Consensus Statement on Analgo-sedation in Neurocritical Care and Review of Literature.

AIM AND OBJECTIVE: Our main objective in developing this consensus is to bring together a set of most agreed-upon statements from a panel of global experts that would act as a guide for clinicians working in neurocritical care units (NCCUs). BACKGROUND: Given the physiological benefits of analgo-sedation in the NCCU, there is little information on their tailoring in the NCCU. This lack of evidence and guidelines on the use of sedation and analgesia in patients with neurological injury leads to a variation in clinical care based on patient requirements and institutional protocols. REVIEW RESULTS: Thirty-nine international experts agreed to be a member of this consensus panel. A Delphi method based on a Web-based questionnaire developed with Google Forms on a secure institute server was used to seek opinions of experts. Questions were related to sedation and analgesia in the neurocritical care unit. A predefined threshold of agreement was established as 70% to support any recommendation, strong, moderate, or weak. No recommendations were made below this threshold. Responses were collected from all the experts, summated, and expressed as percentage (%). After three rounds, consensus could be reached for 6 statements related to analgesia and 5 statements related to sedation. Consensus could not be reached for 10 statements related to analgesia and 5 statements related to sedation. CONCLUSION: This global consensus statement may help in guiding practitioners in clinical decision-making regarding analgo-sedation in the NCCUs, thereby helping in improving patient recovery profiles. CLINICAL SIGNIFICANCE: In the lack of high-level evidence, the recommendations may be seen as the current best clinical practice.

Comparative evaluation of intraoperative use of normal saline, Ringer's lactate, and combination of normal saline and Ringer's lactate in neurosurgical patients - A preliminary randomized clinical trial.

BACKGROUND: Fluid management during intracranial surgery is an important concern. The type of fluid used can have biochemical and metabolic effects during intraoperative management. However, it is yet to be known whether biochemical and metabolic effects have an influence on the clinical outcome of a patient. OBJECTIVE: A prospective evaluation of the effects of normal saline (NS), Ringer's lactate (RL), and a combination of NS and RL on the biochemical, metabolic, and clinical outcomes in patients undergoing intracranial tumor surgery was carried out. MATERIALS AND METHODS: Ninety patients undergoing elective intracranial tumor surgery were randomized to receive NS, RL, or a combination of NS and RL. The biochemical and metabolic parameters were studied at different time points in the intraoperative and postoperative period. The hemodynamic parameters, brain relaxation score at the time of bone flap elevation, postoperative complications, and the duration of hospital stay were the clinical outcome variables of our study. RESULTS: The use of NS was associated with hyperchloremic metabolic acidosis and ionic hypocalcemia. RL caused significant hyponatremia and increase in serum lactate levels. The combination of NS and RL has least influence on biochemical and metabolic parameters. The effects of three fluids were similar on the hemodynamics, brain relaxation score, as well as on postoperative complications and the duration of postoperative hospital stay. CONCLUSION: There are variable effects of NS, RL, or its combination on the biochemical and metabolic parameters in patients undergoing intracranial tumor surgery. However, the clinical outcome of the patients remains similar.

Acute ischemic stroke with tandem/terminal ICA occlusion - CT perfusion based case selection for mechanical recanalization.

BACKGROUND: Rapid reperfusion in a patient with a favorable penumbral pattern is crucial to achieving a good outcome in acute ischemic stroke. Recanalization rates for tandem and terminal internal carotid artery (ICA) occlusion are better with endovascular management as compared with intravenous tissue plasminogen activator (IV-tPA) alone. We hypothesize that tissue-based selection would enable the identification of the ideal patient most suited for reperfusion therapy. We present our series of patients who developed tandem or terminal ICA occlusion and were selected for endovascular management based on their computed tomography (CT) perfusion (CTP) imaging. RESULTS: In this prospective study, 14 (29.16%) of the 48 patients treated by endovascular intervention between January 2011 and March 2014 had either tandem or terminal ICA occlusion. In the tandem group, thrombolysis in cerebral infarction (TICI) 2b/3 reperfusion and a good outcome was observed in five (71.42%, n = 7) and six patients (85.71%, n = 6), respectively. Among the terminal ICA occlusion group, TICI 2b/3 reperfusion and a good outcome was observed in three (42.8%, n = 7) and two patients (28.5%, n = 7), respectively. In patients with early reperfusion, a strong correlation with a median difference of one, in cerebral blood volume (CBV) Alberta Stroke Program Early CT Score (ASPECTS) on CBV map and post-procedure 24-h non-contrast CT, was noted. The median imaging-to-puncture and puncture-to -meaningful reperfusion time was 70 and 68.5 min, respectively, and, overall, good outcomes were seen in 57.1% of the patients. CONCLUSION: The cerebral blood volume (CBV) core estimation reliably predicted the final infarct volume. The key reasons for the significantly better outcomes seen in our cohort were the stringent perfusion imaging-based patient selection and the rapid reperfusion.

Is the modified Mallampati test performed in supine position a reliable predictor of difficult tracheal intubation?

Management of the airway is central to the practice of anesthesia. Several bedside airway assessment methods have been proposed for preoperative identification of patients who are difficult to intubate. The modified Mallampati test (MMT) remains a time-tested technique to date for recognizing an anticipated difficult tracheal intubation as assessed by Cormack-Lehane grade. Both Mallampati and its further modification by Samsoon and Young evaluate patients in the seated position. Recently a study mentioned a change in MMT score from sitting to supine position toward the higher side. However, there is a lack of data regarding the relationship of positional change in MMT with Cormack-Lehane grade. The aim of this prospective study was to assess if MMT score observed in sitting or supine position is a better predictor of difficult tracheal intubation. One hundred and twenty-three patients of ASA physical status I and II, aged 18-60 years, who were scheduled to undergo various neurosurgical procedures were enrolled for the study. We found that the MMT in supine position has a higher positive predictive value and is associated with more true positives as compared to MMT in the sitting position.

Psychosocial concerns in patients with advanced cancer: an observational study at regional cancer centre, India.

INTRODUCTION: The diagnosis and treatment of cancer is associated with substantial physical, psychological, and social morbidity. The objective of this study was to identify the prevalence of psychosocial concerns in the patients with advanced cancer admitted to our institute. MATERIALS AND METHODS: A total of 100 patients admitted to the inpatient palliative care unit of our institute were enrolled in this study. A descriptive questionnaire that dealt with the patient's psychological acceptance of the disease and emotional distress that accompanies the diagnosis was prepared. Patient's social and spiritual needs were addressed, and the future concerns that the patient is preoccupied with were discussed on a one-on-one basis with the patient himself or herself. RESULTS: It was found that a majority of patients, though aware of their diagnosis, were not aware of the disease prognosis. There was a generalized anxiety regarding the treatment of the disease and fear of suffering. Most patients preferred to keep the revelation of the diagnosis to those close to them and not reveal it publicly. Financial drain out of resources was a major concern. Future concerns about their own fitness, the settlement of their children, and the family's well-being were seen commonly in almost all the patients. CONCLUSIONS: Attention to psychosocial and spiritual health needs of patients with cancer is an integral part of an effective palliation, though they are less commonly expressed but are strongly felt by patients with cancer. It is therefore recommended that all clinicians and health care providers should address psychosocial health needs as a part of their routine practice.

Effect of posture on mouth opening and modified Mallampati classification for airway assessment.

Several bedside airway assessment methods have been proposed for preoperatively identifying patients who are difficult to intubate. To date, the Mallampati grading remains a time-tested technique for difficult airway assessment. Both Mallampati and the further modification by Samsoon and Young assessed patients in the seated position. During clinical practice, situations may arise where it may not be feasible for the patient to sit up for airway assessment. The aim of our prospective study was to determine whether there was any difference between the sitting and supine positions for the assessment of Mallampati grade. Eighty adult patients of American Society of Anesthesiologists (ASA) physical status I and II, aged 18-65 years, admitted to our neurosurgical ward were enrolled and assessed for airway. Our study revealed that change in posture produced a significant change in the mouth openings and Mallampati grades of the patients. This change was always toward a higher grade when the patient was turned supine from the sitting position.
