RESUMEN
OBJECTIVE: Wide variations exist in the use of pulmonary artery catheters (PACs) and echocardiography in the field of cardiac surgery. DESIGN: A national survey promoted by the Italian Association of Cardio-Thoracic Anesthesiologists and Intensive Care was conducted. SETTING: The study occurred in Italian cardiac surgery centers (n = 71). PARTICIPANTS: Anesthesiologists-intensivists were enrolled. INTERVENTIONS: Anonymous questionnaires were used to investigate the use of PACs and echocardiography in the operating room (OR) and intensive care unit (ICU). MEASUREMENTS AND MAIN RESULTS: A total of 257 respondents (32.2% response rate) from 59 centers (83.1% response rate) participated. Use of PACs seems less common in ORs (median insertion in 20% [5-70] of patients), with slightly higher use in ICUs; in about half of cases, it was the continuous cardiac output monitoring system of choice. Almost two-thirds of respondents recently inserted at least one PAC within a few hours of ICU admission, despite its need being largely preoperatively predictable. Protocols regulating PAC insertion were reported by 25.3% and 28% of respondents (OR and ICU, respectively). Transesophageal echocardiography (TEE) was performed intraoperatively in >75% of patients by 86.4% of respondents; only 23.7% stated that intraoperative TEE relied on anesthesiologists. Tissue Doppler and/or 3D imaging were widely available (87.4% and 82%, respectively), but only 37.8% and 24.3% of respondents self-declared skills in these modalities, respectively; 77.1% of respondents had no echocardiography certification, nor were pursuing certification (various reasons); 40.9% had not attended recent echocardiography courses. Lower PAC use was associated with university hospitals (OR: p = 0.014, ICU: p = 0.032) and with lower interventions/year (OR: p = 0.023). Higher independence in performing TEE was reported in university hospitals (OR: p < 0.001; ICU: p = 0.006), centers with higher interventions/year (OR: p = 0.019), and by respondents with less experience in cardiology (ICU: p = 0.046). CONCLUSION: Variability in the use of PACs and echocardiography was found. Protocols regulating the use of PACs seem infrequent. University centers use PACs less and have greater skills in TEE. Training and certifications in echocardiography should be encouraged.

Background: The combination of surgery, bacterial spread-out, and artificial cardiopulmonary bypass surfaces results in a release of key inflammatory mediators leading to an overshooting systemic hyper-inflammatory condition frequently associated with compromised hemodynamics and organ dysfunction. A promising approach could be extracorporeal blood purification therapies in combination with IgM enriched immunoglobulin. This approach might perform a balanced control of both hyper and hypo-inflammatory phases as an immune-modulating intervention. Methods: We performed a retrospective observational study of patients with proven infection after cardiac surgery between January 2020 and December 2021. Patients were divided into two groups: (1) the first group (Control Group) followed a standard care approach as recommended by the Surviving Sepsis Campaign Guidelines; The second group (Active Group) underwent extracorporeal blood purification therapy (EBPT) in combination with intravenous administration of IgM enriched immunoglobulin 5 mL/kg die for at least three consecutive days, in conjunction with the standard approach (SSC Guidelines). In addition, ventriculo-arterial (V/A) coupling, Interleukin 6 (IL-6), Endotoxin Activity Assay (EAA), Procalcitonin, White Blood Cells (WBC) counts, Sequential Organ Failure Assessment (SOFA) Score and Inotropic Score were assessed in both two groups at different time points. Results: Fifty-four patients were recruited; 25 were in the Control Group, while 29 participants were in the Active Group. SOFA score significantly improved from baseline [12 (9-16)] until at T 3 [8 (3-13)] in the active group; it was associated with a median EAA reduction from 1.03 (0.39-1.20) at T 0 to 0.41 (0.2-0.9) at T 3 in the active group compared with control group 0.70 (0.50-1.00) at T 0 to 0.70 (0.50-1.00) at T 3 (p < 0.001). V/A coupling tended to be lower in patients of the active arm ranging from 1.9 (1.2-2.7) at T 0 to 0.8 (0.8-2.2) at T 3 than in those of the control arm ranging from 2.1 (1.4-2.2) at T0 to 1.75 (1.45-2.1) at T 3 (p = 0.099). The hemodynamic improvement over time was associated with evident but no significant decrease in inotropic score in the active group compared with the control group. Changes in EAA value from T 0 to T 4 were directly and significantly related (r = 0.39, p = 0.006) to those of V/A coupling. Conclusions: EBPT, in combination with IgM enriched immunoglobulin, was associated with a mitigated postoperative response of key cytokines with a significant decrease in IL-6, Procalcitonin, and EAA and was associated with improvement of clinical and metabolic parameters.
RESUMEN
Cardiac arrest is a hyper-acute condition with a high mortality that requires rapid diagnostics and treatment. As such, point-of-care ultrasound (POCUS) has become a valuable tool in the assessment of these patients. While transthoracic echocardiography (TTE) is the more conventional modality used to find reversible causes of cardiac arrest, transoesophageal echocardiography (TOE) has been increasingly utilised due to its superior image quality, continuous imaging, and ability to be operated away from the patient's chest. TOE also has a number of applications in the aftermath of cardiac arrest, such as during the initiation of extracorporeal cardiopulmonary resuscitation (ECPR) and the subsequent monitoring of extracorporeal membranous oxygenation (ECMO). As TOE has evolved, multiple variations have been developed with different utilities. In this article, we will review the evidence supporting the use of TOE in cardiac arrest and where the different forms of TOE can be applied to evaluate the cardiac arrest patient in a timely and accurate manner.
RESUMEN
BACKGROUND: In Italy, 20 min of continuous, flat-line electrocardiogram are required for death declaration. Despite prolonged warm ischemia time, Italian centers reported good outcomes in controlled donation after circulatory death (cDCD) liver transplantation by combining normothermic regional and end-ischemic machine perfusion (MP). The aim of this study was to evaluate the safety and feasibility of the use of septuagenarian and octogenarian cDCD donors with this approach. METHODS: All cDCD older than 70 y were evaluated during normothermic regional perfusion and then randomly assigned to dual hypothermic or normothermic MP. RESULTS: In the period from April 2021 to December 2022, 17 cDCD older than 70 y were considered. In 6 cases (35%), the graft was not considered suitable for liver transplantation, whereas 11 (65%) were evaluated and eventually transplanted. The median donor age was 82 y, being 8 (73%) older than 80. Median functional warm ischemia and no-flow time were 36 and 28 min, respectively. Grafts were randomly assigned to ex situ dual hypothermic oxygenated MP in 6 cases (55%) and normothermic MP in 5 (45%). None was discarded during MP. There were no cases of primary nonfunction, 1 case of postreperfusion syndrome (9%) and 2 cases (18%) of early allograft dysfunction. At a median follow-up of 8 mo, no vascular complications or ischemic cholangiopathy were reported. No major differences were found in terms of postoperative hospitalization or complications based on the type of MP. CONCLUSIONS: The implementation of sequential normothermic regional and end-ischemic MP allows the safe use of very old donation after circulatory death donors.

Abstract Introduction Percutaneous tracheostomy (PT) in the intensive care unit (ICU) is a well-established practice that shows a reduced risk of wound infection compared with surgical tracheostomy, thus facilitating mechanical ventilation, nursing procedures, reduction in sedation and early mobilization. Objective This is an observational case-control study that compares the results of PT in ICU patients with coronavirus disease 2019 (COVID-19) prospectively enrolled to a similar group of subjects, retrospectively recruited, without COVID-19. Methods Ninety-eight consecutive COVID-19 patients admitted to the ICU at Pisa Azienda Ospedaliero Universitaria Pisana between March 11th and May 20th, 2020 were prospectively studied. Thirty of them underwent PT using different techniques. Another 30 non-COVID-19 ICU patients were used as a control-group. The main outcome was to evaluate the safety and feasibility of PT in COVID-19 patients. We measured the rate of complications. Results Percutaneous tracheostomy was performed with different techniques in 30 of the 98 COVID-19 ICU patients admitted to the ICU. Tracheostomy was performed on day 10 (mean 10 ± 3.3) from the time of intubation. Major tracheal complications occurred in 5 patients during the procedure. In the control group of 30 ICU patients, no differences were found with regards to the timing of the tracheostomy, whereas a statistically significant difference was observed regarding complications with only one tracheal ring rupture reported. Conclusion Percutaneous tracheostomy in COVID-19 patients showed a higher rate of complications compared with controls even though the same precautions and the same expertise were applied. Larger studies are needed to understand whether the coronavirus disease itself carries an increased risk of tracheal damage.
