Prone position ventilation (PPV) has gradually become an adjuvant treatment to improve oxygenation in patients with acute respiratory distress syndrome. Scientific and comprehensive evaluation of the quality of nursing care for patients with PPV is of great significance to ensure the effectiveness of treatment and patient safety. However, there are no established objective indicators for evaluating the quality of nursing care for patients with PPV. This study intended to identify a set of scientific, systematic and clinically applicable nursing-sensitive quality indicators for the care of patients with PPV.Based on the Donabedian structure-process-result theory model, the quality evaluation indicators of nursing care for patients with PPV were preliminarily constructed based on an evidence-based perspective, and two rounds of Delphi surveys were conducted with the purpose of collecting opinions from a panel of independent experts.The questionnaire recovery rates of the two rounds of correspondence were 100.00% and 95.00%, the recovery rates of expert opinions were 80.00% and 26.32%, the expert authority coefficient values were 0.89, and the Kendall coordination coefficient W values were 0.110 and 0.133, respectively. The final nursing-sensitive quality indicators for the care of patients with PPV included 3 first-level indicators, 9 s-level indicators and 29 third-level indicators.The constructed nursing-sensitive quality indicators for the care of patients with PPV involve quality supervision during the whole process of PPV from three dimensions: structure, process and results. These indicators have strong operability, reliability, practicability and scientificity and can provide a reference for the quality evaluation and monitoring of nursing care for patients with PPV.The quality indicators of nursing care for patients with PPV constructed in this research are scientific and reliable, and the content of the quality indicators can better reflect the technical characteristics of special nursing. Nursing managers are encouraged to use these quality indicators to evaluate the quality of clinical nursing care and improve safety for patients with PPV.

Assessing left ventricular diastolic function in prone position

In critically ill patients, standard transthoracic echocardiography (TTE) generally does not facilitate good image quality during mechanical ventilation. We propose a prone-TTE in prone positioned patients, which allows clinicians to obtain a complete apical four-chamber (A-4-C) view. A basic cardiac assessment can be performed in order to evaluate right ventricle function and left ventricle performance, even measuring objective parameters, i.e., tricuspid annular plane systolic excursion (TAPSE); pulmonary artery systolic pressure (PAP), from the tricuspid regurgitation peak Doppler velocity; RV end-diastolic diameter and its ratio to left ventricular end-diastolic diameter; the S’ wave peak velocity with tissue Doppler imaging; the ejection fraction (EF); the mitral annular plane systolic excursion (MAPSE); diastolic function evaluation by the mitral valve; and annular Doppler velocities. Furthermore, by tilting the probe, we can obtain the apical-five-chamber (A-5-C) view, which facilitates the analysis of blood flow at the level of the output tract of the left ventricle (LVOT) and then the estimation of stroke volume. Useful applications of this technique are hemodynamic assessment, titration of fluids, vasoactive drugs therapy, and evaluation of the impact of prone positioning on right ventricle performance and right pulmonary resistances. We believe that considerable information can be drawn from a single view and hope this may be helpful to emergency and critical care clinicians whenever invasive hemodynamic monitoring tools are not available or are simply inconvenient due to clinical reasons.

Echocardiography in Prone Positioned Critically Ill Patients: A Wealth of Information from a Single View

Abstract Purpose Patients with COVID-19 admitted to intensive care unit (ICU) may have right ventricular (RV) injury. The main goal of this study was to investigate the incidence of RV injury and to describe the patient trajectories in terms of RV injury during ICU stay. Methods Prospective and bicentric study with standardized transthoracic echocardiographic (TTE) follow-up during ICU stay with a maximum follow-up of 28 days. The different patterns of RV injury were isolated RV dilation, RV dysfunction (tricuspid annular plane systolic excursion &lt; 17 mm and/or systolic tricuspid annular velocity &lt; 9.5 cm/s and/or RV fractional area change &lt; 35%) without RV dilation, RV dysfunction with RV dilation and acute cor pulmonale (ACP, RV dilatation with paradoxical septal motion). The different RV injury patterns were described and their association with Day-28 mortality was investigated. Results Of 118 patients with complete echocardiographic follow-up who underwent 393 TTE examinations during ICU stay, 73(62%) had at least one RV injury pattern during one or several TTE examinations: 29(40%) had isolated RV dilation, 39(53%) had RV dysfunction without RV dilation, 10(14%) had RV dysfunction with RV dilation and 2(3%) had ACP. Patients with RV injury were more likely to have cardiovascular risk factors, to be intubated and to receive norepinephrine and had a higher Day-28 mortality rate (27 vs. 7%, p &lt; 0.01). RV injury was isolated in 82% of cases, combined with left ventricular systolic dysfunction in 18% of cases and 10% of patients with RV injury experienced several patterns of RV injury during ICU stay. The number of patients with de novo RV injury decreased over time, no patient developed de novo RV injury after Day-14 regardless of the RV injury pattern and 20(31%) patients without RV injury on ICU admission developed RV injury during ICU stay. Only the combination of RV dysfunction with RV dilation or ACP (aHR = 3.18 95% CI(1.16–8.74), p = 0.03) was associated with Day-28 mortality. Conclusion RV injury was frequent in COVID-19 patients, occurred within the first two weeks after ICU admission and was most often isolated. Only the combination of RV dysfunction with RV dilation or ACP could potentially be associated with Day-28 mortality. Clinical trial registration NCT04335162. 

Right ventricular injury in critically ill patients with COVID-19: a descriptive study with standardized echocardiographic follow-up

Background. Myocardial involvement among critically ill patients with coronavirus disease 2019 (COVID-19) often has worse outcomes. An imbalance in the oxygen supply causes the excessive release of pro-inflammatory cytokines, which results in increased ventilation requirements and the risk of death in COVID-19 patients. Purpose. We evaluated the association between the hs-troponin I levels and global longitudinal strain (GLS) as evidence of myocardial involvement among critical COVID-19 patients. Methods. We conducted a prospective cohort study from 1 February to 31 July 2021 at RSUD Dr. Soetomo, Surabaya, as a COVID-19 referral center. Of the 65 critical COVID-19 patients included, 41 (63.1%) were men, with a median age (interquartile range) of 51.0 years (20.0–75.0). Subjects were recruited based on WHO criteria for severe COVID-19, and myocardial involvement in the form of myocarditis was assessed using CDC criteria. Subjects were examined using echocardiography to measure the GLS, and blood samples were taken to measure the hs-troponin. Subjects were then followed for their need for mechanical ventilation and in-hospital mortality. Results. Severe COVID-19 patients with cardiac injury were associated with an increased need for intubation (78.5%) and an increased incidence of myocarditis (50.8%). There was a relationship between the use of intubation and the risk of death in patients (66.7% vs. 33.3%, p-value < 0.001). Decreased GLS and increased hs-troponin were associated with increased myocarditis (p values < 0.001 and 0.004, respectively). Decreased GLS was associated with a higher need for mechanical ventilation (12.17 + 4.79 vs. 15.65 + 4.90, p-value = 0.02) and higher mortality (11.36 + 4.64 vs. 14.74 + 4.82; p-value = 0.005). Elevated hs-troponin was associated with a higher need for mechanical ventilation (25.33% vs. 3.56%, p-value = 0.002) and higher mortality (34.57% vs. 5.76%, p-value = 0.002). Conclusions. Critically ill COVID-19 patients with myocardial involvement and elevated cardiac troponin levels are associated with a higher need for mechanical ventilation and higher mortality.
