Modes of Mechanical ventilation 2017

Background The use of volume-targeted ventilation (VTV) in neonatology has been introduced in the last decade. This study was performed to determine the impact of clinical implementation of volume-targeted conventional mechanical ventilation using the volume guarantee mode in mechanical ventilation of all neonates needing mechanical ventilation compared to pressure-limited ventilation (PLV) modes. The mortality rate, duration of mechanical ventilation, and bronchopulmonary dysplasia were the primary outcomes of the study...

BACKGROUND: The optimal ventilation modalities to manage out-of-hospital cardiac arrest (OHCA) remain debated. A specific pressure mode called cardio-pulmonary ventilation (CPV) may be used instead of manual bag ventilation (MBV). We sought to analyse the association between mechanical CPV and return of spontaneous circulation (ROSC) in non-traumatic OHCA. METHODS: MBV and CPV were retrospectively identified in patients with non-traumatic OHCA from the Belgian Cardiac Arrest Registry...

OBJECTIVE:  This study aimed to examine whether the addition of latency antibiotics in late preterm rupture of membranes (ROM) decreases neonatal infection and increases latency. STUDY DESIGN:  This retrospective two-center study was conducted at Holy Family Hospital (HFH) in Nazareth and Emek Medical Center (EMC) in Afula, on data collected between January 2017 and April 2023. HFH is the smaller institution. EMC and HFH implement similar policies regarding ROM at 340/7 to 366/7 weeks' gestation; the only difference is that a 10-day course of latency antibiotics is implemented at EMC...

OBJECTIVE: To assess the association between use of an oxytocin decision support checklist with oxytocin usage and clinical outcomes. METHODS: We conducted a retrospective cohort study of patients with singleton gestations at 37 weeks and 0 days (37w0d) or greater who received oxytocin during labor from October 2012 to February 2017 at an integrated community healthcare system during three exposure periods: 1) pre-checklist; 2) after paper checklist implementation; and 3) after checklist integration into the electronic medical record (EMR)...

BACKGROUND: Monitoring respiratory effort in ventilated patients is important to balance lung and diaphragm protection. Esophageal manometry remains the gold standard for monitoring respiratory effort but is invasive and requires expertise for its measurement and interpretation. Airway pressures during occlusion maneuvers may provide an alternative, although pediatric data are limited. We sought to determine the correlation between change in esophageal pressure during tidal breathing (∆Pes) and airway pressure measured during three airway occlusion maneuvers: (1) expiratory occlusion pressure (Pocc), (2) airway occlusion pressure (P0...

AIM: To describe the clinical profile, treatment details, intensive care needs, and long-term outcome of children with dilated cardiomyopathy (DCM) associated with Vitamin D deficiency (VDD). MATERIALS AND METHODS: Case records of 14 children with DCM associated with VDD [25(OH)D3 levels <20 ng/mL] admitted to the pediatric intensive care unit (PICU) of a tertiary care teaching hospital between January 2017 and December 2021 were retrospectively analyzed for clinical features, echocardiographic findings, treatment details, intensive care needs, and outcomes...

INTRODUCTION: The driving pressure (ΔP) has an independent association with outcome in patients with acute respiratory distress syndrome (ARDS). INTELLiVENT-Adaptive Support Ventilation (ASV) is a closed-loop mode of ventilation that targets the lowest work and force of breathing. AIM: To compare transpulmonary and respiratory system ΔP between closed-loop ventilation and conventional pressure controlled ventilation in patients with moderate-to-severe ARDS...

BACKGROUND: Bronchopulmonary dysplasia (BPD), an inflammatory-mediated chronic lung disease, is common in extremely preterm infants born before 28 weeks' gestation and is associated with an increased risk of adverse neurodevelopmental and respiratory outcomes in childhood. Effective and safe prophylactic therapies for BPD are urgently required. Systemic corticosteroids reduce rates of BPD in the short-term but are associated with poorer neurodevelopmental outcomes if given to ventilated infants in the first week after birth...

INTRODUCTION: Since the start of the COVID-19 pandemic, we experienced alterations to modes of transportation among trauma patients suffering penetrating injuries. Historically, a small percentage of our penetrating trauma patients use private means of prehospital transportation. Our hypothesis was that the use of private transportation among trauma patients increased during the COVID-19 pandemic and was associated with better outcomes. METHODS: We retrospectively reviewed all adult trauma patients (January 1, 2017 to March 19, 2021), using the date of the shelter-in-place ordinance (March 19, 2020) to separate trauma patients into prepandemic and pandemic patient groups...

BACKGROUND: Mechanical ventilation can lead to the severe impairment of the metabolic pathway of alveolar surfactants, inactivating alveolar surfactants and significantly reducing lung-chest compliance. The cardiopulmonary function of elderly patients usually reduced to a certain extent, and there are lung complications after surgical anesthesia, just like lung barotrauma caused by mechanical ventilation, atelectasis and postoperative hypoxemia. AIM: To investigate the effects of different positive end expiratory pressures (PEEPs) and tidal volumes (VTs) on respiratory function, the degree of the inflammatory response and hemodynamic indexes in patients undergoing surgery under general anesthesia...

BACKGROUND: This study aimed to determine the risk factors of early intraventricular hemorrhage (IVH) in very-low-birth-weight (VLBW) premature infants in China to guide early interventions and improve the survival and quality of life of these infants. METHODS: Data on 421 VLBW premature infants admitted to the neonatal intensive care unit of Tianjin Central Hospital of Gynecology Obstetrics between July 2017 and July 2019 were retrospectively evaluated. Data on head ultrasound results, maternal pregnancy complications, and perinatal conditions were reviewed to evaluate the association between maternal and neonatal factors and the development and severity of IVH...

BACKGROUND: Pediatric mechanical ventilation practice guidelines are not well established; therefore, the European Society for Paediatric and Neonatal Intensive Care (ESPNIC) developed consensus recommendations on pediatric mechanical ventilation management in 2017. However, the guideline's applicability in different health care settings is unknown. This study aimed to determine the consensus on pediatric mechanical ventilation practices from Canadian respiratory therapists' (RTs) perspectives and consensually validate aspects of the ESPNIC guideline...

Background and Objectives : Traditional assessment of the readiness for the weaning from the mechanical ventilator (MV) needs respiratory parameters in a spontaneous breath. Exempted from the MV disconnecting and manual measurements of weaning parameters, a prediction model based on parameters from MV and electronic medical records (EMRs) may help the assessment before spontaneous breath trials. The study aimed to develop prediction models using machine learning techniques with parameters from the ventilator and EMRs for predicting successful ventilator mode shifting in the medical intensive care unit...

Traumatic brain injury (TBI) accounts for around 30% of all trauma-related deaths. Over the past 40 years, TBI has remained a major cause of mortality after trauma. The primary injury caused by the injurious mechanical force leads to irreversible damage to brain tissue. The potentially preventable secondary injury can be accentuated by addressing systemic insults. Early recognition and prompt intervention are integral to achieve better outcomes. Consequently, surgeons still need to be aware of the basic yet integral emergency management strategies for severe TBI (sTBI)...

BACKGROUND: Home mechanical ventilation (HMV) is a viable and effective strategy for patients with chronic respiratory failure (CRF). The Chilean Ministry of Health started a program for adults in 2008. METHODS: This study examined the following data from a prospective cohort of patients with CRF admitted to the national HMV program: characteristics, mode of admission, quality of life, time in the program and survival. RESULTS: A total of 1105 patients were included...

BACKGROUND: The appropriate ventilation mode for one-lung ventilation (OLV) in infants undergoing video-assisted thoracoscopic surgery (VATS) remains controversial. Here we investigated the effect of ventilatory mode "pressure-controlled ventilation-volume guaranteed" (PCV-VG) on the airway pressures and oxygenation parameters by comparing it with volume-controlled ventilation (VCV). METHODS: We retrospectively analyzed the clinical data of infants aged 2 to 12 months who underwent extratracheal bronchial blockage for OLV in our center between January 2017 and August 2020...

OBJECTIVE: To determine the change in non-invasive ventilation (NIV) use over time in infants born at <32 weeks' gestation and the associated clinical outcomes. STUDY DESIGN: Retrospective cohort study using routinely recorded data from the National Neonatal Research Database of infants born at <32 weeks admitted to neonatal units in England and Wales from 2010 to 2017. RESULTS: In 56 537 infants, NIV use increased significantly between 2010 and 2017 (continuous positive airway pressure (CPAP) from 68...

The postglacial Patagonian fjord system along the west coast of southern South America is one of the largest stretches of the southern hemisphere (SH) fjord belt, influenced by the SH westerly wind belt and continental freshwater input. This study reports a 3-year monthly time series (2017-2020) of physical and biogeochemical parameters obtained from the Reloncaví Marine Observatory (OMARE, Spanish acronym) at the northernmost embayment and fjord system of Patagonia. The main objective of this work was to understand the land-atmosphere-ocean interactions and to identify the mechanisms that modulate the density of phytoplankton...

BACKGROUND: The study aimed to examine the effect of early hyperglycemia on the morbidity/mortality of very low birth weight premature infants. METHODS: This retrospective study included all premature infants with gestational age ≤32 gestational weeks, hospitalized at the Department of Intensive Neonatal Care, Clinical Center Kragujevac, during the period 2017-2019. Hyperglycemia was defined as glycemia of ≥12 mmol/l in one measurement, or > 10 mmol/l in two measurements, at repeated intervals of 2-4 hours...

BACKGROUND: Minimally invasive surfactant therapy (MIST) is a promising mode of administration that offers the potential to limit barotrauma and prevent lung injury in preterm infants with respiratory distress syndrome (RDS). OBJECTIVE: This study assessed the effects of the implementation of MIST on safety and efficacy in infants who met criteria for surfactant administration and were treated by MIST as compared with a historical control group treated with surfactant via an endotracheal tube during mechanical ventilation...
