ABSTRACT

OBJECTIVES: Weaning individuals from mechanical ventilation (MV) is a challenge to physicians. Respiratory failure is the main reason for weaning failure (WF), but heart failure plays a pivotal role as well. Transesophageal Doppler (TED) is a minimally invasive method of hemodynamic tracking with fewer problems. The study authors evaluated the role of TED in predicting WF. DESIGN: An observational study. SETTING: A university teaching hospital. PARTICIPANTS: Weaning individuals. INTERVENTIONS: TED was applied before initiating the spontaneous breathing trial (SBT). Hemodynamic parameters, arterial blood gases, and TED (peak velocity [PV], cardiac output [COP]) were reported while cases were on MV before initiating the SBT, and at the successful completion of SBT. Succeeded (group S) and failed individuals (group F, who needed reintubation within 48 hours) were compared. The sensitivity, specificity, and area under the receiver operating curve were calculated. A subgroup of patients with cardiac comorbidities and impaired cardiac contractility was further analyzed. MEASUREMENTS AND MAIN RESULTS: The authors included 39 critically ill patients for weaning from MV. The reintubation rate was 54.8%. In patients with cardiac morbidity, delta change (dC) in PV and COP as predictors of WF showed 100% sensitivity and specificity, with 18% and 14% cut-offs after initiating the SBT (dC between the beginning and end of the successful SBT), respectively. Central venous oxygen saturation revealed a significant difference between patients with cardiac morbidity and noncardiac patients with lower sensitivity and specificity in the prediction of WF. CONCLUSIONS: TED could be a helpful method for the weaning of patients with cardiac morbidity from MV. The dC in PV and COP >18% and >14% were significant predictors of WF in these subjects, respectively.

ABSTRACT

Background: The world urgently requires surrogate markers to diagnose COVID-19 and predict its progression. The severity is not easily predicted via currently used biomarkers. Critical COVID-19 patients need to be screened for hyperinflammation to improve mortality but expensive cytokine measurement is not routinely conducted in most laboratories. The neutrophil-to-lymphocyte ratio (NLR) is a novel biomarker in patients with various diseases. We evaluated the diagnostic and prognostic accuracy of the NLR in COVID-19 patients.Methods: We searched for relevant articles in seven databases. The quantitative analysis was conducted if at least two studies were evaluating the NLR role in COVID-19.Results: We included 8,120 individuals, including 7,482 COVID-19 patients, from 32 articles. Patients with COVID-19 had significantly higher levels of NLR compared to negative individuals. Advanced COVID-19 stages had significantly higher levels of NLR than earlier stages.Expert Opinion: We found significantly higher levels of NLR in advanced stages compared to earlier stages of COVID-19 with good accuracy to diagnose and predict the disease outcome, especially mortality prediction. A close evaluation of critical SARS-CoV-2 patients and efficient early management are essential measures to decrease mortality. NLR could help in assessing the resource allocation in severe COVID-19 patients even in restricted settings.

ABSTRACT

OBJECTIVE: Cardiac surgery for repair of congenital heart defects poses unique hazards to the developing brain. Deep hypothermic circulatory arrest (DHCA) is a simple and effective method for facilitating a bloodless surgical field during congenital heart defect repair. There are, however, some concerns that prolonged DHCA increases the risk of nervous system injury. The electroencephalogram (EEG) is used in adult and, to a lesser extent, pediatric cardiac procedures as a neuromonitoring method. The present study was performed to assess outcomes following DHCA with EEG monitoring in the pediatric population. DESIGN: In this systematic review and meta-analysis, the PubMed, Cochrane Central Register of Controlled Trials, Scopus, Institute of Science Index, and Embase databases were searched from inception for relevant articles. A fixed- or random-effects model, as appropriate, was used. SETTING: Surgical setting. PARTICIPANTS: Pediatric population (≤18 y old). INTERVENTIONS: DHCA (18°C) with EEG monitoring. MEASUREMENTS AND MAIN RESULTS: Nineteen articles with 1,267 pediatric patients ≤18 years were included. The event rate of clinical and EEG seizures among patients who underwent DHCA was 12.9% and 14.9%, respectively. Mortality was found to have a 6.3% prevalence. A longer duration of DHCA was associated with a higher risk of EEG seizure and neurologic abnormalities. In addition, seizures were associated with increased neurologic abnormalities and neurodevelopmental delay. CONCLUSIONS: EEG and neurologic abnormalities were common after DHCA. A longer duration of DHCA was found to lead to more EEG seizure and neurologic abnormalities. Moreover, EEG seizures were more common than clinical seizures. Seizures were found to be associated with increased neurologic abnormalities and neurodevelopmental delay.

ABSTRACT

OBJECTIVE: To the best of our knowledge, no bibliometric studies have characterised the paediatric anaesthesia research in Ireland. In this study, we aim to analyse the research output from two anaesthetic departments in Irish paediatric hospitals. METHODS: A Scopus database search was conducted to identify the publications from 2007 to 2018 of the departments of anaesthesia and intensive care medicine in the Children's University Hospital, Temple Street (CUH), and Our Lady's Children's Hospital, Crumlin (OLCHC). RESULTS: The Irish publications in paediatric anaesthesia and intensive care included 108 publications. CUH and OLCHC published 37 (34.9%) and 73 (68.8%) documents, respectively, with 6 (5.6%) documents affiliated with both hospitals. The number of original research articles was 28 (75.7%) for CUH versus 46 (63%) for OLCHC. The number of published reviews was 5 (13.5%) for CUH versus 11 (15.1%) for OLCHC. Over the last 2 years (2016, 2017), the number of OLCHC publications was almost double (13 and 14 publications) that of CUH (4 and 6 publications). For CUH, only two publications were in specialised journals. For OLCHC, 18 publications were in specialised journals, in addition to four publications in high-ranked journals. The mean impact factor for CUH publications was 3.78 (standard deviation [SD], 7.19) versus 4.52 (SD, 10.56) for OLCHC. From OLCHC, 20 authors published with a median h-index of 2.00 (interquartile range, 0-4.25), versus 14 authors form CUH with a median h-index of 1.50 (1.00-4.50). CONCLUSION: Anaesthetic publications from the two Irish paediatric hospitals are unexceptional and with limited cooperation between the two hospitals. Research plans should be implemented.
