Background: The combination of prone positioning and extracorporeal membrane oxygenation (ECMO) in patients with acute respiratory distress syndrome (ARDS) is recognized as safe but its use has been limited due to potential complications. Aim: To report the prevalence of pressure ulcers and other complications due to prone positioning in adult patients receiving veno–venous ECMO. Study Design: This cross‐sectional study was conducted in a tertiary level intensive care unit (ICU) in Milan (Italy), between January 2015 and December 2019. The study population was critically ill adult patients undergoing veno–venous ECMO. Statistical association between pressure ulcers and the type of body positioning (prone versus supine) was explored fitting a logistic model. Results: In the study period, 114 patients were treated with veno–venous ECMO and 62 (54.4%) patients were placed prone for a total of 130 prone position cycles. ECMO cannulation was performed via femoro–femoral configuration in the majority of patients (82.4%, 94/114). Pressure ulcers developed in 57.0% of patients (95%CI: 44.0%–72.6%), most often arising on the face and the chin (37.1%, 23/62), particularly in those placed prone. The main reason of prone positioning interruption was the decrease of ECMO blood flow (8.1%, 5/62). The fitted model showed no association between body position during ECMO and occurrence of pressure ulcers (OR 1.3, 95%CI: 0.5–3.6, p =.532). Conclusions: Facial pressure ulcers were the most frequent complications of prone positioning. Nurses should plan and implement evidence‐based care to prevent such pressure injuries in patients undergoing ECMO. Relevance to Clinical Practice: The combination of prone positioning and ECMO shows few life‐threating complications. This manoeuvre during ECMO is feasible and safe when performed by experienced ICU staff. [ABSTRACT FROM AUTHOR]

Introduction Oral care, using either a mouth rinse, gel, toothbrush, or combination of them, together with aspiration of secretions, may reduce the risk of ventilator-acquired pneumonia in intubated patents. Oral care procedure in patients on venovenous extracorporeal membrane oxygenation (VV-ECMO) may cause bleeding due to the systemic anticoagulation required. Purpose The aim of this study was to investigate the rate of bleeding episodes during oral care in patients supported by VV-ECMO. Methods A retrospective observational study was performed. All patients admitted to an Italian ECMO center during 2014 were included in the study. Results Data from 14 patients were analyzed. The median intensive care unit length of stay was 39.0 days (interquartile range, 27.3-83.3 days), and median days on VV-ECMO was 19.5 (10.3-46.0). There were 440 ECMO days, with 1320 oral care maneuvers. In 7 patients, bleeding episodes occurred: 2 with orotracheal intubation and 5 initially managed with orotracheal intubation, thereafter via Translaryngeal tracheostomy tube (according to Fantoni's technique). In 61 oral care procedures (4.6%), bleeding was detected during or after the maneuver, whereas the total numbers of days with at least 1 bleeding episode were 35 (8%). The presence or absence of bleeding during ECMO days was statistically significant for international normalized ratio (1.01 [0.95-1.11] vs 1.13 [1.03-1.25], P < .0001), platelets (163 000 [93 500-229 000] vs 61 000 [91 00--100 000], P < .0001), and mouth care score (6 [5-7] vs 8 [7-9], P < .001). Conclusion Oral care can cause bleeding in patients on VV-ECMO. Implementation of protocols for daily oral care in patients on ECMO may reduce risks. As recommended by the literature, this category of patients should be treated in selected centers distinguished by a regular volume of ECMO activity and the presence of dedicated ECMO specialist nurses.

Objective: To study incidence, type, etiology, risk factors, and impact on outcome of nosocomial infections during extracorporeal membrane oxygenation.Design: Retrospective analysis of prospectively collected data.Setting: Italian tertiary referral center medical-surgical ICU.Patients: One hundred five consecutive patients who were treated with extracorporeal membrane oxygenation from January 2010 to November 2015.Interventions: None.Measurements and Main Results: Ninety-two patients were included in the analysis (48.5 [37-56] years old, simplified acute physiology score II 37 [32-47]) who underwent peripheral extracorporeal membrane oxygenation (87% veno-venous) for medical indications (78% acute respiratory distress syndrome). Fifty-two patients (55%) were infected (50.4 infections/1,000 person-days of extracorporeal membrane oxygenation). We identified 32 ventilator-associated pneumonia, eight urinary tract infections, five blood stream infections, three catheter-related blood stream infections, two colitis, one extracorporeal membrane oxygenation cannula infection, and one pulmonary-catheter infection. G+ infections (35%) occurred earlier compared with G- (48%) (4 [2-10] vs. 13 [7-23] days from extracorporeal membrane oxygenation initiation; p < 0.001). Multidrug-resistant organisms caused 56% of bacterial infections. Younger age (2-35 years old) was independently associated with higher risk for nosocomial infections. Twenty-nine patients (31.5%) died (13.0 deaths/1,000 person-days of extracorporeal membrane oxygenation). Infected patients had higher risk for death (18 vs. 8 deaths/1,000 person-days of extracorporeal membrane oxygenation; p = 0.037) and longer ICU stay (32.5 [19.5-78] vs. 19 [10.5-27.5] days; p = 0.003), mechanical ventilation (36.5 [20-80.5] vs. 16.5 [9-25.5] days; p < 0.001), and extracorporeal membrane oxygenation (25.5 [10.75-54] vs. 10 [5-13] days; p < 0.001). Older age (> 50 years old), reason for connection different from acute respiratory distress syndrome, higher simplified acute physiology score II, diagnosis of ventilator-associated pneumonia, and infection by multidrug-resistant bacteria were independently associated to increased death rate.Conclusions: Infections (especially ventilator-associated pneumonia) during extracorporeal membrane oxygenation therapy are common and frequently involve multidrug-resistant organisms. In addition, they have a negative impact on patients' outcomes. [ABSTRACT FROM AUTHOR]
