Intraoperative and Intraprocedural Use of 3-Dimensional Transesophageal Echocardiography: An International European Association of Cardiothoracic Anesthesia and Intensive Care Survey of Cardiac Surgical Centers.

OBJECTIVE: To assess the intraoperative use of 3-dimensional transesophageal echocardiography (3D TEE) in cardiac surgical centers, the authors created a survey aimed at evaluating the availability of equipment and the use of 3D TEE for specific surgical and interventional procedures and single-image modalities. The respondents were asked to identify the perceived impact on patient management and current limitations to its routine use. DESIGN: A multiple choice 25-question online survey submitted to the members of the European Association of Cardiothoracic Anesthesia and Intensive Care (EACTAIC) on December 6, 2021, and closed on January 31, 2022. SETTING: An online survey. PARTICIPANTS: Registered EACTAIC members in 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 239 respondents from 44 different countries took part in the survey (27% of the total 903 EACTAIC members). Most respondents (59%) were TEE-certified by the National Board of Echocardiography, European Association of Cardiovascular Imaging (EACVI/EACTAIC), or had a national certificate. Of the respondents, 68% had no formal 3D TEE training. Eight percent of respondents had no 3D machines, whereas 40% had one for each operating room, and 33% had only one for the entire operating room block. 3D TEE was performed most frequently in more than 67% of cases for mitral valve surgery, and in more than 54% of cases for mitral and tricuspid clips, aortic valve, tricuspid valve, and aortic surgery. CONCLUSION: Current guidelines suggest integrating 3D TEE into all comprehensive examinations. The authors' survey reported that intraoperative 3D TEE was used in the majority of mitral valve surgery and only one-half of the other valve surgeries and transcatheter procedures. Its use may be explained by the availability of 3D machines, trained personnel, and limited time to perform TEE in the operating room. Educational initiatives for training in 3D TEE may further increase its routine use.

Apex Resection in Zebrafish (Danio rerio) as a Model of Heart Regeneration: A Video-Assisted Guide.

Ischemic heart disease is one of the leading causes of deaths worldwide. A major hindrance to resolving this challenge lies in the mammalian hearts inability to regenerate after injury. In contrast, zebrafish retain a regenerative capacity of the heart throughout their lifetimes. Apex resection (AR) is a popular zebrafish model for studying heart regeneration, and entails resecting 10-20% of the heart in the apex region, whereafter the regeneration process is monitored until the heart is fully regenerated within 60 days. Despite this popularity, video tutorials describing this technique in detail are lacking. In this paper we visualize and describe the entire AR procedure including anaesthesia, surgery, and recovery. In addition, we show that the concentration and duration of anaesthesia are important parameters to consider, to balance sufficient levels of sedation and minimizing mortality. Moreover, we provide examples of how zebrafish heart regeneration can be assessed both in 2D (immunohistochemistry of heart sections) and 3D (analyses of whole, tissue cleared hearts using multiphoton imaging). In summary, this paper aims to aid beginners in establishing and conducting the AR model in their laboratory, but also to spur further interest in improving the model and its evaluation.

Lung segmentectomy assisted by highly selective independent segmental ventilation: a series of three cases.

BACKGROUND: The identification of targeted intersegmental planes and resection with adequate surgical margins are among the crucial steps in anatomical pulmonary segmentectomy, and technical improvements are still needed. CASE PRESENTATION: We reported three cases of intersegmental plane identification using highly selective independent segmental ventilation during segmentectomy. All cases required cooperation with an anesthesiologist who was able to perform segmental ventilation and double confirmation of segmental bronchus branches by the surgeon. The surgical procedure provides a direct visualization of spare segment inflation and saves time in deflation over the conventional residual segment inflation method. CONCLUSIONS: Highly selective independent segmental ventilation could be considered a suitable option for pulmonary intersegmental plane identification and could be universally used for lung segmentectomy.

Best practice in cardiac anesthesia during the COVID-19 pandemic: Practical recommendations.

The COVID-19 outbreak has influenced the entire health care system, including cardiac surgery. In this review, the authors reveal practical aspects that are important during the COVID-19 pandemic with regards to the safe delivery of cardiac anesthesia. Timing for operations of the cardio-vascular system may be well programmed in most cases. Hence, the level of priorities must be defined for any single patient. The postponement of surgery may be convenient for most cases, if it is made in the best interest of the patient. The preanesthetic evaluation should be attentive of the respiratory history of the patient. Cardiac anesthesia always implies some respiratory monitoring; hence the existing clinical situation of the patient's respiratory system should be clear. In case of emergency surgery, the patient should be treated as if they potentially have or are at risk for the virus. In the case of a COVID-19 confirmed or suspected patient, attention must be made to preserve operating room and team integrity. The machineries are to be draped with plastic to simplify the disinfection after the operation. Perioperative management of suspected or confirmed COVID-19 patients must strictly follow the most relevant international guidelines. This review article has synthesized the common aspects present in the most important of these.

Opioid-Sparing Cardiac Anesthesia: Secondary Analysis of an Enhanced Recovery Program for Cardiac Surgery.

BACKGROUND: Cardiac anesthetics rely heavily on opioids, with the standard patient receiving between 70 and 105 morphine sulfate equivalents (MSE; 10-15 µg/kg of fentanyl). A central tenet of Enhanced Recovery Programs (ERP) is the use of multimodal analgesia. This study was performed to assess the association between nonopioid interventions employed as part of an ERP for cardiac surgery and intraoperative opioid administration. METHODS: This study represents a post hoc secondary analysis of data obtained from an institutional ERP for cardiac surgery. Consecutive patients undergoing cardiac surgery received 5 nonopioid interventions, including preoperative gabapentin and acetaminophen, intraoperative dexmedetomidine and ketamine infusions, and regional analgesia via serratus anterior plane block. The primary objective, the association between intraoperative opioid administration and the number of interventions provided, was assessed via a linear mixed-effects regression model. To assess the association between intraoperative opioid administration and postoperative outcomes, patients were stratified into high (>50 MSE) and low (≤50 MSE) opioids, 1:1 propensity matched based on 15 patients and procedure covariables and assessed for associations with postoperative outcomes of interest. To investigate the impact of further opioid restriction, ultralow (≤25 MSE) opioid participants were then identified, 1:3 propensity matched to high opioid patients, and similarly compared. RESULTS: A total of 451 patients were included in the overall analysis. Analysis of the primary objective revealed that intraoperative opioid administration was inversely related to the number of interventions employed (estimated -7.96 MSE per intervention, 95% confidence interval [CI], -9.82 to -6.10, P < .001). No differences were detected between low (n = 136) and high (n = 136) opioid patients in postoperative complications, postoperative pain scores, time to extubation, or length of stay. No differences were found in outcomes between ultralow (n = 63) and high (n = 132) opioid participants. CONCLUSIONS: Nonopioid interventions employed as part of an ERP for cardiac surgery were associated with a reduction of intraoperative opioid administration. Low and ultralow opioid use was not associated with significant differences in postoperative outcomes. These findings are hypothesis-generating, and future prospective studies are necessary to establish the role of opioid-sparing strategies in the setting of cardiac surgery.

Functional Modular Network Identifies the Key Genes of Preoperative Inhalation Anesthesia and Intravenous Anesthesia in Off-Pump Coronary Artery Bypass Grafting.

Off-pump coronary artery bypass grafting (OPCABG) is an effective strategy for revascularization. Preoperative anesthesia appears critical due to surgical instability and the risk of organ damage. This study, based on a functional module network, analysed the effects of preoperative inhalation anesthesia and intravenous anesthesia on OPCABG and performed a pivot analysis of its potential drug regulators. We obtained microarray data of sevoflurane anesthesia and propofol anesthesia from the GEO database and analysed the difference between the two groups of data, resulting in 5701 and 3210 differential genes to construct the expression matrix. WGCNA analysis showed that sevoflurane anesthesia clustered into 7 functional disorder modules, including PDCD6IP, WDR3, and other core genes; propofol anesthesia clustered to form two functional disorder modules, including KCNB2 and LHX2, two core genes Enrichment analysis of the functions and pathways of interest suggests that both anesthesia-related module genes tend to function as pathways associated with ion and transmembrane transport. The underlying mechanism may be that targeted regulation of transmembrane-associated biological processes and ion pathways in the core genes of each module affect the surgical process. Pivot analysis of potential drug regulators revealed 229 potential drugs for sevoflurane anesthesia surgery, among which zinc regulates three functional disorder modules via AHSG, F12, etc., and 67 potential drugs for propofol anesthesia surgery, among which are propofol, methadone, and buprenorphine, regulate two functional disorder modules through four genes, CYP2C8, OPRM1, CYP2C18, and CYP2C19. This study provides guidance on clinical use or treatment by comparing the effects of two anesthesias on surgery and its potential drugs.

The Cutting Edge of Thoracic Anesthesia During the Coronavirus Disease 2019 (COVID-19) Outbreak.

Coronavirus disease 2019 (COVID-19) has quickly spread globally, causing a real pandemic. In this critical scenario, lung cancer patients scheduled for surgical treatment need to continue to receive optimal care while protecting them from an eventual severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Adequate use of personal protective equipment (PPE) during aerosol-generating procedures (AGPs) and a COVID-19 specific intraoperative management are paramount in order to prevent cross infections. New suggestions or improvement of existing contagion control guidance are needed, even in case of non-symptomatic patients, possibly responsible for virus spread.

Anesthesia management of atrial myxoma resection with multiple cerebral aneurysms: a case report and review of the literature.

BACKGROUND: Embolic stroke is a common complication of atrial myxoma, whereas multiple cerebral aneurysms associated with atrial myxoma is rare. The pathogenesis of the cerebral vascular disease related to an atrial myxoma is still not well known, and there are no guidelines to guide treatment and anesthesia management in such patients. CASE PRESENTATION: In this report, we present a 38-year-old woman with occasional dizziness and headache diagnosed as multiple cerebral fusiform aneurysms, in whom transthoracic echocardiography revealed a mass attached to the interatrial septum in the left atrium. Myxoma resection was performed in fast track cardiac surgery pathway without neurological complications, and no intervention was carried out on the cerebral aneurysms. She was discharged home 6 days after the procedure for followed-up. Furthermore, we reviewed and analyzed the literature in the PubMed and Google Scholar databases in order to conclude the optimal treatment in such cases. CONCLUSIONS: Atrial myxoma-related cerebral aneurysms are always multiple and in a fusiform shape in most occasions. Early resection of myxoma and conservative therapy of aneurysm is an optimal treatment. TEE and PbtO2 monitoring play an essential role in anesthesia management. Fast track cardiac anesthesia is safe and effective to early evaluate neurological function. Long term follow-up for "myxomatous aneurysms" is recommended. And outcome of most patients is excellent.

Thoracic Anesthesia of Patients With Suspected or Confirmed 2019 Novel Coronavirus Infection: Preliminary Recommendations for Airway Management by the European Association of Cardiothoracic Anaesthesiology Thoracic Subspecialty Committee.

The novel coronavirus has caused a pandemic around the world. Management of patients with suspected or confirmed coronavirus infection who have to undergo thoracic surgery will be a challenge for the anesthesiologists. The thoracic subspecialty committee of European Association of Cardiothoracic Anaesthesiology (EACTA) has conducted a survey of opinion in order to create recommendations for the anesthetic approach to these challenging patients. It should be emphasized that both the management of the infected patient with COVID-19 and the self-protection of the anesthesia team constitute a complicated challenge. The text focuses therefore on both important topics.

Congenital heart disease in adults (when kids grow up) pediatric geriatric anesthesia.

PURPOSE OF REVIEW: The current review focuses on the new development of adult congenital heart disease (ACHD) patients in the areas of imaging, percutaneous interventions, ventricular assist devices and transplantation. RECENT FINDINGS: Since the last ACHD publication in the journal, several advances have been made in the evaluation and treatment of these patients. As CHD patients' longevity increases pregnancy, comorbities and acquired heart disease become a concern. Recent data show that the incidence of complications in low-risk CHD is not higher that the regular population. In addition, breakthrough research in percutaneous valve implantation has been published showing good outcomes but needing intensive care recovery in a significant number of patients. In the ACHD heart failure population, assist device and transplant fields mounting evidence shows that these therapies should not be the last resort since low-risk ACHD patient may have similar outcomes to those with acquired heart disease. Finally risk stratification is important in ACHD to define better ways to recover from surgery and anesthesia. SUMMARY: The field of anesthesia for ACHD is growing with new indications for diagnostic, interventional and surgical procedures. Tailoring cardiac and noncardiac care to the different risk profile in ACHD patients will be defined in the next few years. VIDEO ABSTRACT: Motta summary clip: http://links.lww.com/COAN/A65.

Noteworthy Literature in Cardiac Anesthesia for 2019.

This article represents a selective review of literature published in 2019. Initial results from PubMed searching for a combination of terms, including cardiac anesthesiology and anesthesiology outcomes, yielded more than 1400 publications. From there, we manually screened the results and identified 5 major themes for the year of 2019, including transcatheter techniques, delirium and anesthesiology, coagulation management following cardiopulmonary bypass, perfusion management with del Nido cardioplegia, and applied clinical research. The following research accomplishments have expanded what is possible and set ambitious goals for the future.

Restricted versus liberal intraoperative benzodiazepine use in cardiac anaesthesia for reducing delirium (B-Free Pilot): a pilot, multicentre, randomised, cluster crossover trial.

BACKGROUND: Delirium is common after cardiac surgery and is associated with adverse outcomes. Perioperative benzodiazepine use is associated with delirium and is common during cardiac surgery, which may increase the risk of postoperative delirium. We undertook a pilot study to inform the feasibility of a large randomised cluster crossover trial examining whether an institutional policy of restricted benzodiazepine administration during cardiac surgery (compared with liberal administration) would reduce delirium. METHODS: We conducted a two-centre, pilot, randomised cluster crossover trial with four 4 week crossover periods. Each centre was randomised to a policy of restricted or liberal use, and then alternated between the two policies during the remaining three periods. Our feasibility outcomes were adherence to each policy (goal ≥80%) and outcome assessment (one delirium assessment per day in the ICU in ≥90% of participants). We also evaluated the incidence of intraoperative awareness in one site using serial Brice questionnaires. RESULTS: Of 800 patients undergoing cardiac surgery during the trial period, 127/800 (15.9%) had delirium. Of these, 355/389 (91.3%) received benzodiazepines during the liberal benzodiazepine periods and 363/411 (88.3%) did not receive benzodiazepines during the restricted benzodiazepine periods. Amongst the 800 patients, 740 (92.5%) had ≥1 postoperative delirium assessment per day in the ICU. Of 521 patients screened for intraoperative awareness, one patient (0.2%), managed during the restricted benzodiazepine period (but who received benzodiazepine), experienced intraoperative awareness. CONCLUSIONS: This pilot study demonstrates the feasibility of a large, multicentre, randomised, cluster crossover trial examining whether an institutional policy of restricted vs liberal benzodiazepine use during cardiac surgery will reduce postoperative delirium.
