Comparison of Oxygen Delivery Devices in Postoperative Patients with Hypoxemia: An Open-labeled Randomized Controlled Study.

Background: Acute hypoxemic respiratory failure is among the more commonly occurring complications in postoperative patients. Supplemental oxygen and addressing the primary etiology form the basis of its treatment. Materials and methods: We conducted an open-labeled randomized control trial with 90 adult patients and compared three oxygen delivery vehicles (ODV), i.e., noninvasive ventilation (NIV), high-flow nasal cannula (HFNC), and venturi mask (VM) in postoperative hypoxemic patients. The primary outcome variable was a change in the P/F ratio after 2 hours of use of ODV. Results: It was observed that the change in P/F ratio after 2 hours was similar in all three ODV groups (p = 0.274). The mean values of the post-ODV P/F ratio were comparable with the pre-ODV P/F ratio in all three modalities. The P/F ratio after HFNC was 358.08 ± 117.95; after NIV was 357.60 ± 220.67; and after VM was 355.47 ± 101.90 (p = 0.997). Conclusion: Among HFNC, NIV, and VM, none of the devices proved superior to the other for use in postoperative hypoxemia.

Comparison of Modified ROX Index Score and ROX Index Score for Early Prediction of High Flow Nasal Oxygen Therapy Outcome in Patients with Acute Respiratory Failure: A Prospective Observational Cohort Study.

Background: We compared the modified ROX index and ROX index scores in earlier predictions of high-flow nasal oxygen (HFNO) therapy outcomes in patients with acute respiratory failure. Methods: We conducted a prospective observational study on 151 acute respiratory failure patients initiated on HFNO therapy. The primary objective of this research was to compare the modified ROX index and ROX index to investigate which score predicted HFNO treatment outcome earlier. Results: The modified ROX index score had better predictive power than the ROX score at different time points, especially one hour following the start of HFNO therapy (AUC 0.790; 95% CI: 0.717-0.863; p < 0.001). For the ROX Index at 1 hour, the ideal cut-off value for HFNO outcome was 4.36 (sensitivity: 72.6%, specificity: 53.9%), and for the modified ROX index at 1 hour, it was 4.63 (sensitivity: 74.2%, specificity: 69.7%). The presence of various comorbidities didn't show any change in ROX-HR cut-off values. Conclusion: The modified ROX index is a better predictor of the success of HFNO therapy than the ROX index. Furthermore, the presence of any comorbidities did not affect modified ROX index cut-off values or the outcome of HFNO therapy.

Comparison of Diagnostic Accuracy of Presepsin and Procalcitonin for Sepsis in Critically Ill Patients: A Prospective Observational Study.

Objective: Early diagnosis of sepsis is crucial to institute appropriate therapy and then to avert a possible negative outcome. We planned this study to evaluate the diagnostic value of presepsin, its sensitivity and specificity for diagnosing sepsis in critically ill patients, and its ability to prognosticate the outcome of sepsis. Methods: In this prospective observational study, adult patients admitted to the intensive care unit (ICU) at our institute were screened, and those with features suggestive of sepsis were recruited into the study. Procalcitonin (PCT) and presepsin were assessed on the day of admission and day 7 of the ICU stay, apart from routine investigations. Patients were followed for outcome in terms of mortality till 28 days. Results: The study comprised 82 patients who satisfied the inclusion criteria. Presepsin sensitivity for sepsis diagnosis was determined to be 78%, while that of PCT was determined to be 69%. This gave a combined sensitivity of presepsin and PCT of 93% when used in parallel for the diagnosis of sepsis. Conclusion: A combination of PCT and presepsin provides higher sensitivity and can be used to screen for sepsis in the ICU.

Oxygen Cylinder Fire during the COVID-19 Pandemic.

The coronavirus disease-2019 (COVID-19) pandemic has resulted in the massive utilization of oxygen cylinders during the treatment of patients. This rapid turnover has necessitated their frequent replacements. Infection control measures have encouraged the use of alcohol-based sanitizers. Over-enthusiastic or inappropriate use of these solutions may increase the risk of fire. We report an unfortunate incident of accidental fire arising out from the integration of fuel, a source of ignition, and oxygen. We also discuss the proper practices to minimize such mishaps.

Comparison of Norepinephrine and Terlipressin vs Norepinephrine Alone for Management of Septic Shock: A Randomized Control Study.

Purpose: To compare norepinephrine and terlipressin vs norepinephrine alone for management of septic shock. Materials and methods: In this prospective, randomized control trial, 50 adult patients with septic shock were randomized into two groups. Group I received a combination of injection terlipressin 0.02 µg/kg/min (fixed dose) infusion and injection norepinephrine 0.01 µg/kg/min infusion and group II received injection norepinephrine 0.01 µg/kg/min infusion alone. Dose of noradrenaline in both the groups was titrated to achieve the target MAP of 65-70 mm Hg. The data collected were the dose of norepinephrine required to maintain an MAP of above 65 mm Hg, urine output, serum lactate, procalcitonin level, C-reactive protein, sequential organ failure assessment (SOFA) score, total duration of vasopressor support, and incidences of the adverse effects. Results: The norepinephrine dose in group I vs group II at 12 hours was found to be 0.141 ± 0.067 vs 0.374 ± 0.096 µg/kg/min (p ≤0.005). The serum lactate was lower, and urine output was higher in group I than group II (p <0.05). Group I had a significantly greater reduction in SOFA score in 12 hours than group II. Group I patient also had a significant decrease in the duration of vasopressor administration than group II patients being discharged from the ICU. However, there was no difference in the mortality between the two groups during their ICU stay. Conclusion: A low-dose continuous infusion of terlipressin and norepinephrine could help attain early resuscitation goals for managing patients with septic shock.

Postpartum Hypernatremia with Extrapontine Rhabdomyelinolysis: A Case Report.

Hypernatremia (serum sodium>160 meq/L) present with diverse neurological manifestations, ranging from flaccid paralysis to impaired cognition, encephalopathy, and even deep coma. Osmotic demyelination refers to changes in brain cells because of an acute change in plasma osmolality. It is further divided into two types, i.e., central pontine myelinolysis (CPM) and extrapontine myelinolysis (EPM). Patients with EPM, besides spasticity, may also present with other movement disorders such as catatonia, parkinsonism, and dystonia. We present a case of a postpartum woman bought to the emergency department by her relatives in an unconscious state. In view of poor sensorium (Glasgow coma scale < 7), she was intubated and received mechanical ventilatory support. On admission, computed tomography ofthebrain was normal, and the patient was transferred to the intensive care unit (ICU) for further management. The preliminary work-up in the ICU showed hypernatremia (serum sodium of 182 mEq/L) with hyper-osmolality (359 mOsm/kgH2O). She was managed as per the ICU protocol for hypernatremia. During her ICU stay, her sensorium improved, but she developed flaccid paralysis and was quadriplegic. Thus, a tracheostomy was performed, and she was weaned from the ventilator. After ventilator weaning, she was transferred to the ward for further rehabilitation. During rehabilitation, the patient was able to sit and takefoodorally.To date, only a few cases are reported in postpartum women with acute severe hypernatremia caused by high-grade fever and loss of body fluids leading to extra-pontine demyelination and flaccid paralysis. This case highlightsthat prompt recognition and appropriate intervention can improve the outcomes in these patients.

Use of rotational thromboelastometry to predict the outcome of COVID-19 patients: A retrospective observational study.

Background and Aims: The hypercoagulability occurring in COVID-19 patients is detected only by Rotational thromboelastometry (ROTEM). However, the benefit of performing ROTEM in the management of disease and predicting the outcome of COVID-19 patients is yet to be established. Material and Methods: The data of 23 critically ill and 11 stable COVID-19 adult patients were extracted from the hospital information system admitted between July and August 2020 and patient charts and analyzed retrospectively. The critically ill patients were divided as a survivor and non-survivor groups. The Intrinsic pathway part of ROTEM (INTEM) and Fibrinogen part of ROTEM (FIBTEM) were performed on day 0 for both critically ill and stable patients, and on day 10 for critically ill patients. The statistical package for social science (SPSS) version 26 was used for statistical analysis. Results: The median FIBTEM amplitude at 5 min (A5) and maximum clot firmness (MCF) were elevated in both stable and critically ill patients (24 vs 27 mm, P = 0.46 and 27.5 vs 40 mm, P = 0.011) with a significant difference in FIBTEM MCF. But there was no significant difference between number of survivors and non-survivors with FIBTEM MCF >25 at day 0 and day 10. Conclusion: The Hypercoagulability state as detected by ROTEM parameters at day 0 and day 10 had no association with the outcome (mortality) of critically ill COVID-19 patients. Hence it cannot be used as a prognostic test. The increasing age, comorbidities and D-dimer values were associated with a poor prognosis in COVID-19 patients.

Clinical profile of bloodstream infections in COVID-19 patients: a retrospective cohort study.

BACKGROUND: Bloodstream infections (BSIs) are an emerging cause of significant morbidity and mortality in severe Coronavirus disease 2019 (COVID-19). We aimed to assess the prevalence, clinical profile and outcome of BSIs in critically ill COVID-19 patients. METHODS: This was a single-centre retrospective study conducted at a tertiary care hospital in Western India. All patients (age > 18 years) with reverse-transcription polymerase chain reaction (RT-PCR) confirmed COVID-19 admitted in the intensive care unit (ICU) were included. Hospital electronic records were searched for demographic data, time of bloodstream infection since admission, clinical profile, antimicrobial resistance pattern and clinical outcome of all patients who developed BSIs. RESULTS: Out of 750 patients admitted in COVID ICU, 8.5% developed secondary BSIs. All severe COVID-19 patients who developed BSIs succumbed to illness. A significant proportion of BSIs were Gram-negative pathogens (53/64, 82.8%). Acinetobacter baumannii was the commonest isolate, followed by Klebsiella pneumoniae (32.8% and 21.9%, respectively). Multidrug-resistance organisms (MDRO) were found in 57.8% of the cases. The majority of MDRO belonged to K. pneumoniae and Enterococcus groups. The proportion of Gram-negative bacteria resistant to carbapenems was 47.2% (25/53). On multivariate analysis, raised total leukocyte counts, mechanical ventilation and presence of comorbidities were significantly associated with the incidence of BSIs. CONCLUSION: We found a significant prevalence of Acinetobacter baumannii in COVID-19 associated BSIs. The presence of comorbidities raised leukocyte counts and mechanical ventilation should alarm clinicians for possible BSIs. The timely initiation of empirical antibiotics and rapid de-escalation is vital to improve the outcome. At the same time, strict compliance of infection control practices should be accomplished to reduce the occurrence of MDRO.

Mucormycosis: A Case Series of Patients Admitted in Non-COVID-19 Intensive Care Unit of a Tertiary Care Center during the Second Wave.

Rhino-orbital-cerebral mucormycosis is an invasive fungal infection associated with mortality of 25-62%. There has been a surge in the number of cases during this second wave of coronavirus disease-2019 (COVID-19) in India. We report 10 cases of mucormycosis admitted to our adult intensive care unit. After reviewing the patient's information, we found that 60% of patients had received steroids, and most had uncontrolled blood sugar levels. Most patients received treatment with surgical debridement and antifungal, although the mortality rate was as high as 40%. We report two unique cases of renal and gastrointestinal mucormycosis as well. We concluded that poor glycemic control was the primary etiology behind the rise in the number of cases. Our report also stresses the importance of early surgical intervention and suggests further research comparing the efficacy of combination antifungal therapy versus single antifungal (amphotericin B) to help resource-limited settings in these times of drug crisis.

Atypical Presentation of Crimean-Congo Hemorrhagic Fever as Ascending Paralysis with Rhabdomyolysis.

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease caused by a arbovirus. It is asymptomatic in infected animals but a serious threat to the health of individuals. In human, it starts with nonspecific febrile diseases and progresses into severe hemorrhagic syndrome with high-casual fatality. Here, we report a case of CCHF with atypical presentation of ascending paralysis and rhabdomyolysis. HOW TO CITE THIS ARTICLE: Prasad HR, Sharma A, Kothari N, Vyas V, Goyal S.

PKCδ-IRAK1 axis regulates oxidized LDL-induced IL-1ß production in monocytes.

This study examined the role of interleukin (IL)-1 receptor-associated kinase (IRAK) and protein kinase C (PKC) in oxidized LDL (Ox-LDL)-induced monocyte IL-1ß production. In THP1 cells, Ox-LDL induced time-dependent secretory IL-1ß and IRAK1 activity; IRAK4, IRAK3, and CD36 protein expression; PKCδ-JNK1 phosphorylation; and AP-1 activation. IRAK1/4 siRNA and inhibitor (INH)-attenuated Ox-LDL induced secreted IL-1ß and pro-IL-1ß mRNA and pro-IL-1ß and mature IL-1ß protein expression, respectively. Diphenyleneiodonium chloride (NADPH oxidase INH) and N-acetylcysteine (free radical scavenger) attenuated Ox-LDL-induced reactive oxygen species generation, caspase-1 activity, and pro-IL-1ß and mature IL-1ß expression. Ox-LDL-induced secretory IL-1ß production was abrogated in the presence of JNK INH II, Tanshinone IIa, Ro-31-8220, Go6976, Rottlerin, and PKCδ siRNA. PKCδ siRNA attenuated the Ox-LDL-induced increase in IRAK1 kinase activity, JNK1 phosphorylation, and AP-1 activation. In THP1 macrophages, CD36, toll-like receptor (TLR)2, TLR4, TLR6, and PKCδ siRNA prevented Ox-LDL-induced PKCδ and IRAK1 activation and IL-1ß production. Enhanced Ox-LDL and IL-1ß in systemic inflammatory response syndrome (SIRS) patient plasma demonstrated positive correlation with each other and with disease severity scores. Ox-LDL-containing plasma induced PKCδ and IRAK1 phosphorylation and IL-1ß production in a CD36-, TLR2-, TLR4-, and TLR6-dependent manner in primary human monocytes. Results suggest involvement of CD36, TLR2, TLR4, TLR6, and the PKCδ-IRAK1-JNK1-AP-1 axis in Ox-LDL-induced IL-1ß production.

Artificial intelligence in pediatric airway - A scoping review.

Artificial intelligence is an ever-growing modality revolutionizing the field of medical science. It utilizes various computational models and algorithms and helps out in different sectors of healthcare. Here, in this scoping review, we are trying to evaluate the use of Artificial intelligence (AI) in the field of pediatric anesthesia, specifically in the more challenging domain, the pediatric airway. Different components within the domain of AI include machine learning, neural networks, deep learning, robotics, and computer vision. Electronic databases like Google Scholar, Cochrane databases, and Pubmed were searched. Different studies had heterogeneity of age groups, so all studies with children under 18 years of age were included and assessed. The use of AI was reviewed in the preoperative, intraoperative, and postoperative domains of pediatric anesthesia. The applicability of AI needs to be supplemented by clinical judgment for the final anticipation in various fields of medicine.

Safety and complications of labour epidural analgesia in obese parturients: worrying is not worth the weight!

The physiological transformations accompanying pregnancy, compounded by the implications of obesity, pose intricate challenges for anaesthesiologists attending to obese parturients. Obesity makes it harder to successfully provide epidural analgesia to a parturient. This narrative review explains the most recent data on the safety and complications of providing labour epidural analgesia in obese expectant mothers. We have emphasised the evidence-based approaches that are the most effective for obese pregnant mothers receiving labour epidural analgesia.
