İntensive care monitoring

BACKGROUND: Respiratory viral infections, particularly influenza, are known to cause significant morbidity and mortality, often due to secondary infections. Our aim was to comparatively analyze the incidence, epidemiology, and outcomes of secondary pneumonia in adult patients hospitalized with influenza versus noninfluenza viral infections and determine whether influenza particularly predisposes to secondary infections. METHODS: This was a retrospective analysis from a single tertiary medical center of adult patients admitted to the hospital between 2008 and 2010 with respiratory viral infections...

PURPOSE: Monitoring of physiological parameters is a major concern in Intensive Care Units (ICU) given their role in the assessment of vital organ function. Within this context, one issue is the lack of efficient noncontact techniques for respiratory monitoring. In this paper, we present a novel noncontact solution for real-time respiratory monitoring and function assessment of ICU patients. METHODS: The proposed system uses a Time-of-Flight depth sensor to analyze the patient's chest wall morphological changes in order to estimate multiple respiratory function parameters...

PROBLEM: Given the complex interaction among patients, individual providers, health care teams, and the clinical environment, patient safety events with serious consequences are most likely to occur in intensive care units, operating rooms, and emergency departments (EDs). With low-frequency, high-risk events such as pediatric resuscitations, health care teams working in EDs may not have the clinical opportunity to identify deficiencies, review and reinforce knowledge and skills, and problem solve in authentic clinical conditions...

Extremely preterm infants' hemodynamic instability places them at high risk of brain injury. Currently there is no reliable bedside method to continuously monitor cerebral hemodynamics in the neonatal intensive care unit (NICU). This paper reports a feasibility study to adapt and test an innovative speckle contrast diffuse correlation tomography (scDCT) device for noncontact, high-density, 3D imaging of cerebral blood flow (CBF) in preterm infants. The scDCT scans a focused point near-infrared illumination to multiple source positions for deep tissue penetration, and controls an electron multiplying charge-coupled-device camera with thousands of pixels to achieve a high-density sampling...

INTRODUCTION: Severe coronavirus disease 2019 (COVID-19) is characterised by hyperinflammatory state, systemic coagulopathies, and multiorgan involvement, especially acute respiratory distress syndrome (ARDS). We here describe our preliminary clinical experience with COVID-19 patients treated via an early initiation of extracorporeal blood purification combined with systemic heparinisation and respiratory support. METHODS: Fifteen patients were included; several biomarkers associated with COVID-19 severity were monitored...

BACKGROUND: Patients with severe COVID-19 develop hyperferritinemic inflammation, a rare sepsis-like immune dysregulation syndrome. METHODS: Stratified treatment decisions in a cross-location telemedical interdisciplinary case conference were assessed in this retrospective cohort study. A standardized treatment algorithm including continuous positive airway pressure and noninvasive ventilation was implemented. A locally developed COVID inflammation score (CIS) defined patients at risk for severe disease...

BACKGROUND: Dedifferentiated liposarcoma (DDLPS) is a rare malignancy that transitions from an atypical lipomatous tumor to a sarcoma with a variable morphologic appearance. The behavior of this tumor in the retroperitoneum is aggressive, but the behavior of DDLPS in the extremities is less well-defined because it is rare. Few reports have assessed the imaging features and clinical outcomes of primary DDLPS in the extremities. QUESTIONS/PURPOSES: In patients with primary DDLPS of the extremity, we asked the following questions: (1) How frequently do additional primary malignancies occur in patients with DDLPS? (2) What is the rate of overall survival, metastases, and local recurrence in DDLPS? (3) What factors are associated with metastasis-free survival and local recurrence in DDLPS? METHODS: We defined DDLPS as a biphasic neoplasm that transitions from an atypical lipomatous tumor (ALT) to a sarcoma of variable morphologic appearance and histologic grades...

Noninvasive ventilation (NIV) and high-flow nasal cannulae therapy (HFNCT) are first-line methods of treatment for children presenting with acute respiratory distress, with paediatric intensive care units (PICUs) providing an ideal environment for subsequent treatment monitoring. However, the availability of step-down units, where NIV and HFNCT can be safely utilised, has reduced the need for such patients to be admitted to PICUs, thereby leading to the better overall utilisation of critical care resources...

Introduction: Hemodynamic stability and fluid responsiveness (FR) assume importance in perioperative management of patients undergoing major surgery. Passive leg raising (PLR) is validated in assessing FR in intensive care unit patients. Very few studies have examined FR to PLR in intraoperative scenario. We prospectively studied FR to PLR using transesophageal echocardiography (TEE), in patients with no coronary artery disease (CAD) undergoing major neurosurgery and those with CAD undergoing coronary artery bypass grafting (CABG)...

Coronaviruses are RNA viruses that can cause disease in the upper and lower respiratory tract in humans and animals. Lately, a new coronavirus causing pneumonia cases was detected in Wuhan, China in December 2019. Soon after, the name of the virus was identified as the "severe acute respiratory syndrome coronavirus-2", and the World Health Organization named the disease coronavirus disease-2019 (COVID-19). In our country, the first cases began to appear in the second week of March. In this study, we aimed to investigate the demographic characteristics and risk factors of patients with the diagnosis of COVID-19...

INTRODUCTION: Anesthetic care in patients undergoing thoracic surgery presents specific challenges that require a multidisciplinary approach to management. There remains a need for standardized, evidence-based, continuously updated guidelines for perioperative care in these patients. METHODS: A multidisciplinary expert group, the Perioperative Anesthesia in Thoracic Surgery (PACTS) group, was established to develop recommendations for anesthesia practice in patients undergoing elective lung resection for lung cancer...

BACKGROUND Neonatal acute leukemia is a rare condition. Little is known about its incidence and outcomes, and treatment options have not been standardized. CASE REPORT A 3-day old, apparently healthy male newborn was referred to the pediatric intensive care unit with multiple violaceous macules and a few papules on his face and upper trunk. After initial spontaneous regression, the lesions reappeared. Skin biopsy and bone marrow aspirate revealed a diagnosis of acute lymphoblastic leukemia (ALL). ALL induction therapy was initiated on day 24, resulting in morphological remission at the end of induction therapy...

PURPOSE: There is a need for bedside methods to monitor oxygen delivery in the microcirculation. Near-infrared spectroscopy commonly measures tissue oxygen saturation, but does not reflect the time-dependent variability of microvascular hemoglobin content (MHC) that attempts to match oxygen supply with demand. The objective of this study is to determine the feasibility of MHC monitoring in critically ill patients using high-resolution near-infrared spectroscopy to assess perfusion in the peripheral microcirculation...

The aim of this Intensive Care Medicine Rapid Practice Guideline (ICM-RPG) is to formulate an evidence-based guidance for the use of neuromuscular blocking agents (NMBA) in adults with acute respiratory distress syndrome (ARDS). The panel comprised 20 international clinical experts from 12 countries, and 2 patient representatives. We adhered to the methodology for trustworthy clinical practice guidelines and followed a strict conflict of interest policy. We convened panelists through teleconferences and web-based discussions...

This audit of airway incidents was conducted over six months in 12 tertiary level hospitals across Australia and New Zealand. During that time, 131,233 patients had airway management and 111 reports were submitted (incidence 0.08%). The airway incidents included a combination of difficult airway management (83), oxygen desaturation (58), aspiration (19), regurgitation (14), laryngospasm (16), airway bleeding (10), bronchospasm (5) and dental injury (4), which gave a total of 209 events in 111 reports. Most incidents occurred during general anaesthesia (GA; 83...

OBJECTIVE: The objective of this study was to determine the frequency and clinical correlates of different electroencephalographic patterns and their association with clinical outcomes in critically ill patients. SUBJECTS AND METHODS: This retrospective cross-sectional study was performed in the Neurology Department of King Fahd Hospital of the University, Kingdom of Saudi Arabia and involved a review and analysis of medical records pertaining to 179 intensive care unit patients who underwent electroencephalography (EEG) in the June to November 2018 period...

Radiation dose is important in radiotherapy. Too little, and the treatment is not effective, too much causes radiation toxicity. A biochemical measurement of the effect of radiotherapy would be useful in personalisation of this treatment. This study evaluated changes in exhaled breath volatile organic compounds (VOC) associated with radiotherapy with thermal desorption gas chromatography mass-spectrometry followed by data processing and multivariate statistical analysis. Further the feasibility of adopting gas chromatography ion mobility spectrometry for radiotherapy point-of-care breath was assessed...

The use of point of care ultrasound to assess cardiovascular function performed by a neonatologist who is not a cardiologist, is gaining interest in the neonatal intensive care unit (NICU). Clinical signs such as heart rate, blood pressure and capillary refill time provide limited insight into the adequacy of systemic blood flow and organ perfusion. Functional echocardiography (echo) enables real time evaluation of cardiac performance, identifying the nature of cardiovascular compromise, guiding therapeutic decisions and monitoring response to treatment...

Apnea of prematurity affects the majority of infants born before 34 weeks of complete gestation. Significant recurrent apnea of prematurity is associated with both short and long term complications and is a risk factor for increased mortality and neurodevelopmental disability. The current review discusses the recent advances in the understanding of the pathophysiology of apnea of prematurity, as well as the clinical questions relevant to physicians and staff treating infants with apnea of prematurity. Finally, we discuss monitoring and discharge decisions, and present recommendations following discharge from the neonatal intensive care unit...

Introduction: Recently, a rapidly increasing number of e-cigarette or vaping induced lung injury (EVALI) has been reported across the nation. Given the ongoing epidemic, it has been suggested that specific chemical substances used as additives in e-cigarettes could be highly related to EVALI. A history of vaping with positive radiographic changes and low suspicion for active infection are requirements for diagnosis but it still remains a diagnosis of exclusion. The course of the disease, mechanism of lung injury and the optimal management options need to be better understood...
