A routine vascular procedure, the central venous catheterization requires recognition of malposition to avoid its serious sequelae. This case report discusses the complications encountered following presumed right internal jugular vein cannulation in a trauma patient. Cervical spine imaging done as part of a trauma protocol revealed a catheter in the right vertebral vein. Inadvertently mispositioned catheter emphasizes the significance of ultrasound-guided central vein catheterization even if the cannulation is done using standard anatomical landmarks.

Dystonia is a movement disorder characterized by involuntary sustained or intermittent muscle contraction causing repetitive twisting movements and abnormal postures. Status dystonicus (SD) is an enigmatic disease of cryptic etiology. We hereby report a child with West syndrome (WS) who went on to develop SD following intramuscular adrenocorticotropic hormone (ACTH) injection. An 11-month-old male child presented with complaints of flexor spasms for 2 months. The diagnosis of WS was confirmed by electroencephalography (EEG), which showed hypsarrhythmia. Intramuscular ACTH was added, and oral trihexyphenidyl was started for dystonia. On day 7 of ACTH, the child developed frequent opisthotonic posturing. Management protocol for grade IV SD was initiated. Administration of N-terminal of ACTH in rat locus coeruleus has been shown to produce human dystonia-like movement and abnormal posturing.

Elizabethkingia meningoseptica is an opportunistic pathogen increasingly reported as hospital-acquired infection. Here, we report a series of cases of eight patients with invasive E. meningoseptica infections over a period of 27 months in a tertiary teaching hospital from South India. Age range was 45 days to 84 years, median 66 years, with male preponderance. Associated risk factors included recent hospitalization with surgeries, diabetes mellitus, renal failure, mechanically ventilated, and central line. All isolates were susceptible to minocycline. Combination therapy with ciprofloxacin and piperacillin tazobactam was most common. Six recovered and two patients were lost to follow-up.

Aim: To determine the utility of the HACOR score in predicting weaning failure in resource-limited settings.

Objectives: The primary objective was to determine a cut-off value of the HACOR score, sensitivity, and specificity to predict failed weaning. The secondary objective was to determine which out of five components of the score was significantly different between the successful weaning and the failed weaning groups.

Introduction: Most weaning indices are either inaccurate or are dependent on complex ventilatory parameters, which are difficult to measure in resource-limited settings. This study aimed to determine the utility of the HACOR score consisting of heart rate, acidosis, consciousness level, oxygenation, and respiratory rate as a predictor of weaning in the intensive care unit.

Materials and methods: It was a prospective observational study on 120 patients between 18 and 90 years. The HACOR score was evaluated at 30 minutes of spontaneous breathing trial (SBT). The total duration of SBT was 120 minutes.

Results: Out of 120 patients, 83 (69.2%) had successful weaning, whereas 37 (30.8%) had weaning failure. The median and interquartile range (IQR) of the HACOR score in the successful weaning group was 2 (0-3) and 6 (5-8) in the failed weaning group (p-value <0.001). There was a significant difference in each of the five components of the HACOR score between the successful and failed weaning groups (p <0.05). HACOR score ≥5 predicted failed weaning, sensitivity 83.8%, specificity 96.4%, area under the curve (AUC) 0.950, and 95% confidence interval (CI) [0.907-0.993], p <0.001. Multivariable logistic regression analysis showed that HACOR score ≥5 is an independent predictor of weaning failure [p <0.001, 95% CI (1.9-4.2), adjusted odds ratio 2.82].

Conclusion: A HACOR score ≥5 is an excellent predictor of weaning failure. This score may be useful as a weaning strategy in the intensive care unit.

Ethical approval: Prior to the commencement of the study, Institutional Ethics Committee permission was obtained (IEC: 197/2021) and Clinical Trial Registry of India (CTRI) registration was done before recruitment (CTRI/2021/07/035139). We obtained written informed consent from the legally authorized representative prior to recruiting patients for the study.

Background: Acute respiratory distress syndrome (ARDS) is characterized by dysregulated inflammation resulting in hypoxemia and respiratory failure and causes both morbidity and mortality.

Objectives: To describe the clinical profile, outcome, and predictors of mortality in ARDS in children admitted to the Pediatric intensive care unit.

Materials and methods: This is a single-center retrospective study conducted at a tertiary referral hospital in a 12-bed PICU involving children (1 month to 18 years) with ARDS as defined by Pediatric Acute Lung Injury Consensus Conference (PALICC) guidelines, over a period of 5 years (2016-2020). Demographic, clinical, and laboratory details at onset and during PICU stay were collected. Predictors of mortality were compared between survivors and non-survivors.

Results: We identified 89 patients with ARDS. The median age at presentation was 76 months (12-124 months). The most common precipitating factor was pneumonia (66%). The majority of children (35.9%) had moderate ARDS. Overall mortality was 33% with more than half belonging to severe ARDS group (58%). On Kaplan-Meier survival curve analysis, the mean time to death was shorter in the severe ARDS group as compared to other groups. Multiorgan dysfunction was present in 46 (51.6%) of the cases. Non-survivors had higher mean pediatric logistic organ dysfunction (PELOD2) on day 1. PRISM III at admission, worsening trends of ventilator and oxygenation parameters (OI, P/F, MAP, and PEEP) independently predicted mortality after multivariate analysis.

Conclusion: High PRISM score predicts poor outcome, and worsening trends of ventilator and oxygenation parameters (OI, P/F, MAP, and PEEP) are associated with mortality.

Introduction: Chronically critically ill (CCI) patients often have high costs of care and poor outcomes. Disease management programs offering home care may reduce costs but need buy-in from informal caregivers. An understanding of caregiver burden in this population is lacking. We aimed to study the caregiver burden, its change over time, and factors affecting it, in post-ICU tracheostomized patients. We compared the caregiver burden among CCI carers to that of palliative caregivers.

Materials and methods: Informal caregivers of thirty chronically critically ill tracheostomized patients (CGcci) were administered the Caregivers Burden Scale (CBS) tool at discharge, 2 and 4 weeks after discharge. A one-point assessment of burden was made in 30 caregivers of patients enrolled in Pain and Palliative care clinic (CGpc). Linear mixed models for repeated measures were used to analyze score of CGcci over time and compared to the burden in physical, psychologic, economic, time, and social domains between groups.

Results: All 60 caregivers were young (33-35 years), predominantly male, and children of the patients. Both CGcci and CGpc had moderate burden score of 60.5 (14.7) vs 61.5 (13), respectively. Physical burden (11.5 vs 8) was greater in CGcci (p = 0.001) compared to psychologic domain (10 vs 12.5) in CGpc (p = 0.01). Burden score over all domains in CGcci decreased rapidly from 67.5 (8) to 55 (16.5) (p = 0.001) in the first month after discharge.

Conclusion: Burden of care among caregivers of tracheostomized chronically critically ill patients is comparable to those of palliative caregivers and reduces significantly with time.

Introduction: The Centres for Disease Control and Prevention (CDC) introduced a new definition of ventilator-associated events (VAEs) in 2013 in place of longstanding ventilator-associated pneumonia (VAP) definition. Three entities under VAE, ventilator-associated condition (VAC), infection-related ventilator-associated complication (IVAC), and possible ventilator-associated pneumonia (PVAP), were introduced.

Objectives: To assess the incidence of all VAEs in a tertiary care trauma ICU and to find the predictive value of VAE and sensitivity of VAE definitions for VAP.

Design: Cohort prospective study at trauma intensive care unit (ICU) of PGIMER, Chandigarh, from July 2018 till June 2019.

Materials and methods: Patients admitted in trauma ICU were checked for VAP and VAE criteria defined by CDC.

Results: Four hundred and sixty five patients were observed. Around 378 patients were included in the study with 4046 patient days and 3031 mechanical ventilation (MV) days. Incidence rate of PVAP, IVAC, VAC, and VAP was 2.97, 6.60, 10.23, and 9.24 per 1000 ventilator days, respectively. Sensitivity, specificity, positive predictive value, and negative predictive value (NPV) of diagnosing VAP were 0.61, 0.97, 0.68, and 0.97 for VAC; 0.80, 0.97, 0.57, and 0.99 for IVAC; and 0.78, 0.94, 0.25, and 0.9 for PVAP, respectively. Kendall's W test showed that there was very poor concordance between VAP and VAE.
