Monitoring Macro- and Microcirculation in the Critically Ill: A Narrative Review.

Circulatory shock is a common and important diagnosis in the critical care environment. Hemodynamic monitoring is quintessential in the management of shock. The currently used hemodynamic monitoring devices not only measure cardiac output but also provide data related to the prediction of fluid responsiveness, extravascular lung water, and also pulmonary vascular permeability. Additionally, these devices are minimally invasive and associated with fewer complications. The area of hemodynamic monitoring is progressively evolving with a trend toward the use of minimally invasive devices in this area. The critical care physician should be well-versed with current hemodynamic monitoring limitations and stay updated with the upcoming advances in this field so that optimal therapy can be delivered to patients in circulatory shock.

The impact of a "short-term" basic intensive care training program on the knowledge of nonintensivist doctors during the COVID-19 pandemic: An experience from a population-dense low- and middle-income country.

BACKGROUND: The utility of basic intensive care unit (ICU) training comprising a "1-day course" has been scientifically evaluated and reported in very few studies, with almost no such study from resource-limited settings. AIM: The study assessed the utility of basic ICU training comprising of a "1-day course" in increasing the knowledge of nonintensivist doctors. MATERIALS AND METHODS: This is an observational study conducted at a medical university in North India in 2020. The participants were nonintensivist doctors attending the course. The course was designed by intensivists, and it had four domains. The participants were categorised on the basis of their duration of ICU experience and broad speciality. Pretest and posttest was administered, which was analysed to ascertain the gain in the knowledge score. RESULTS: A total of 252 participants were included, of which the majority were from the clinical medicine speciality (85.3%) and had ICU experience of 1-6 months (47.6%). There was a significant improvement in the mean total score of the participants after training from 14/25 to 19/25, with a mean difference (MD) of 5.02 (p < 0.001). Based on ICU experience, in groups I (<1 month), II (1-6 months), and III (>6 months), there was a significant improvement in the total score of the participants after training with MD with 95% confidence interval (CI) limits of 5.27 (4.65-5.90), 4.70 (4.38-5.02), and 5.33 (4.89-5.78), respectively. In the clinical surgery specialty (n = 37), there was a significant improvement in the total score after training from 11/25 to 16.4/25 with an MD (95% CI limits) of 5.38 (4.4-6.3). Similarly, in the clinical medicine group (n = 215), the MD (95% CI limits) score after training was 4.95 (4.71-5.20), from 14.5/25 to 19.5/25. In feedback, more than half of the participants showed interest in joining ICU after training. CONCLUSIONS: Training nonintensivist doctors for 1 day can be useful in improving their knowledge, regardless of their prior ICU experience and speciality.

A Challenging Diagnosis of Sheehan's Syndrome in Non-obstetric Critical Care and Emergency Settings: A Case Series of Five Patients with Varied Presentations.

Sheehan's syndrome is a life-threatening endocrine emergency seen in postpartum females secondary to ischemic pituitary necrosis. It is a frequent cause of hypopituitarism in developing countries that occurs secondary to postpartum haemorrhage (PPH). Patients with Sheehan's syndrome often present with organ dysfunctions in critical care settings, secondary to stressors precipitating the underlying hormonal deficiencies. The initial clinical picture of Sheehan's syndrome may mimic some other disease, leading to misdiagnosis and diagnostic delay. Strict vigilance, timely diagnosis, and appropriate management are essential to avoid diagnostic delay and to improve the patient outcome. In this case series, we describe 5 cases of previously undiagnosed Sheehan's syndrome (including young, middle aged and postmenopausal females) that presented to critical care and emergency settings with organ failures.

Acute Methanol Toxicity: Clinical Correlation with Autopsy Findings, a Descriptive Study.

BACKGROUND: Methyl alcohol poisoning or deaths from drinking illegally brewed cheap alcohol which is often spiked with chemicals to increase its potency are frequent in India. Many outbreaks from different parts of the country have been reported from time to time. A total of 11,830 lives were lost between 2006 and 2015 due to the consumption of spurious liquor in the country. The symptoms can range from mild to severe depending upon factors like the amount of exposure and time of presentation. AIMS AND OBJECTIVES: The present study was designed to describe the clinical presentation, management, and outcome of the patients during a recent methanol outbreak that can form a basis for diagnosis and management. This study also highlights the salient autopsy findings and their correlation with clinical features. MATERIALS AND METHODS: It is a retrospective, descriptive study discussing clinical features of patients with methanol intoxication, their outcome, and the clinical correlation with autopsy findings of patients who succumbed to death. The study was conducted at King George's Medical University, Lucknow. The patients were enrolled from a methanol intoxication outbreak in Barabanki district on 28th May 2019 followed by a similar outbreak in Sitapur district two days later. RESULTS: A total of 33 patients were included in this study based on predefined clinical characteristics. The average amount of alcohol consumed was about 223 mL (range: 100-300 mL). The majority of patients had onset of symptoms between 12 and 24 hours. All patients had gastrointestinal symptoms, 97% of patients had visual disturbances, 91% of patients had central nervous system manifestation while frank coma was observed in 15% of patients. Decreased urine output was reported in 6% of patients. About 90% of patients had metabolic acidosis. Out of 33 patients included in this study, 30 patients were discharged in stable condition while two died and one absconded. Autopsy findings revealed marked cerebral edema and hyperemia, hyperemic heart, and congested lungs in all the patients. One patient showed putaminal necrosis which is characteristic of methanol poisoning. Kidneys in two cases were hyperemic and show parenchymal degeneration which co-relates with both patients being anuric. CONCLUSION: Methanol intoxication is a serious problem in developing countries like ours. Timely intervention is an important factor in reducing mortality among these patients. The study highlights the very important fact that methanol intoxication can be managed at the very ground level with minimal resources (as available) if intervened and recognized in time.

Cytomegalovirus Coinfection in Critically Ill Patients with Novel Coronavirus-2019 Disease: Pathogens or Spectators?

Coronavirus disease-2019 (COVID-19) pandemic is raging all over the world. As we are delving more into management of COVID-19, certain new challenges are emerging. One of these is emergence or reactivation of viral infections belonging to Herpesviridae family, especially cytomegalovirus (CMV). Although we have come across the threat of fungal and resistant bacterial infections, experience regarding reactivation or coinfection with concomitant viral infections like CMV during the COVID pandemic is still limited. Whether CMV is a bystander or pathogen is difficult to say categorically and needs further research. In this case series, we intend to describe three patients of COVID-19 with CMV coinfections. To our knowledge, this is the first case series from India. How to cite this article: Siddiqui SS, Chatterjee S, Yadav A, Rai N, Agrawal A, Gurjar M, et al.

Albumin Kinetics in Sepsis and COVID-19.

Hypoalbuminemia has been associated with poor outcome in critically ill population including sepsis and COVID-19. The observational study by Su et al showed a favorable albumin kinetics, with an initial downwards trend followed by recovery back to the predicted albumin levels, in survivors of COVID-19 and sepsis-induced acute respiratory distress syndrome (ARDS). However, nonsurvivors in COVID-19 group did not have an upwards recovery slope, while those in sepsis group did not follow any sort of albumin kinetics. Thus, authors concluded that the pattern of albumin kinetics may be predictive of outcome in COVID-19 and sepsis-induced ARDS. Here, we would like to highlight a few more points in this letter.

The evolution of clot strength in critically ill COVID-19 patients: a prospective observational thromboelastography study.

The authors have done commendable work in exploring the utility of a comprehensive viscoelastic test for assessment of the coagulation cascade in Coronavirus disease 2019 (COVID-19) patients. This article published in your esteemed journal in November 2021 "The evolution of clot strength in critically-ill COVID-19 patients: a prospective observational thromboelastography study" found hypercoagulability in most of the patients at Intensive Care Unit (ICU) admission and also noted a persistently increased fibrin contribution to clot strength. However, we would like to comment upon a few points which may be of importance to the readers.
