Background: With growing concerns about opioid-related risks, efforts to reduce opioid use throughout the perioperative period have increased. This study aimed to compare postoperative recovery outcomes between opioid-free anesthesia (OFA) and opioid-sparing anesthesia (OSA) under a multimodal analgesic protocol in video-assisted thoracoscopic surgery (VATS). Methods: A retrospective cohort study was conducted on 196 patients undergoing VATS from August 2019 to December 2021. Patients received either dexmedetomidine-based OFA or remifentanil-based OSA. Postoperative recovery was assessed using the Quality of Recovery-15 (QoR-15) score, opioid consumption, and pain intensity. Additionally, opioid-related complications and intraoperative hemodynamic changes were evaluated. Results: Both groups showed similar QoR-15 scores 24 h postoperatively (124.2 ± 7.0 vs. 123.0 ± 6.9, p = 0.227). Opioid consumption and pain intensity were comparable, and the incidence of opioid-related adverse events did not significantly differ between the groups. Intraoperative hypotension and bradycardia were more frequent in the OFA group, but the differences were not statistically significant. Conclusions: The study concluded that both OFA and OSA, when used under a multimodal analgesic protocol, provided effective postoperative recovery in patients undergoing VATS with no significant differences in outcomes.

The coronavirus disease 2019 pandemic brought about many changes in the delivery of healthcare, graduate medical education, and collaborative efforts across academic medicine. While there was a temporary disruption in the fluid delivery of services, longer-term benefits emerged with the leveraging of innovative technology and multicenter collaborations. These new opportunities led 14 centers in the United States and Europe to develop a novel, remote, and collaborative educational effort in cardiovascular and thoracic anesthesiology, known as the Transatlantic Educational Network. This paper describes the initial pilot structure and preimplementation data and provides a rationale for the development and expansion of the pilot program in other areas of anesthesiology.

Opioids effectively manage perioperative pain but have numerous adverse effects. Opioid-free anesthesia (OFA) eliminates intraoperative opioid use; however, evidence for its use in video-assisted thoracoscopic surgery (VATS) is limited. This study assessed the effect of OFA using ketamine in VATS patients compared to opioid-sparing anesthesia (OSA). A total of 91 patients undergoing VATS lobectomy or segmentectomy were randomized to either the OFA group (ketamine) or the OSA group (remifentanil). The primary outcome was the quality of recovery (QoR) on postoperative day (POD) 1, measured with the QoR-40 questionnaire. Secondary outcomes included postoperative pain scores and adverse events. Both groups had comparable baseline and surgical characteristics. On POD 1, the QoR-40 score was higher in the OFA group than in the OSA group (164.3 ± 10.8 vs. 158.7 ± 10.6; mean difference: 5.6, 95% CI: 1.1, 10.0; p = 0.015), though this did not meet the pre-specified minimal clinically important difference of 6.3. The visual analog scale score was lower in the OFA group as compared to the OSA group at 0–1 h (4.2 ± 2.3 vs. 6.2 ± 2.1; p < 0.001) and 1–4 h after surgery (3.4 ± 1.8 vs. 4.6 ± 1.9; p = 0.003). The OFA group had a lower incidence of PONV (2 [4.4%] vs. 9 [19.6%]; p = 0.049) and postoperative shivering (4 [8.9%] vs. 13 [28.3%]; p = 0.030) than the OSA group at 0–1 h after surgery. Using OFA with ketamine proved feasible, as indicated by the stable intraoperative hemodynamics and absence of intraoperative awareness. Patients undergoing VATS with OFA using ketamine showed a statistically significant, but clinically insignificant, QoR improvement compared to those receiving OSA with remifentanil.

Abstract Background The objective of this study was to evaluate a modern combined video laryngoscopy and flexible fiberoptic bronchoscope approach to placement of a double lumen endobronchial tube and further characterize potential strengths and weaknesses of this approach. Methods Retrospective chart review was conducted at our single institution, academic medical center, tertiary-care hospital. Patients aged 18 years of age or older were evaluated who underwent thoracic surgery and one-lung ventilation with placement of a double lumen endobronchial tube using a novel combined video laryngoscopy and flexible fiberoptic bronchoscope approach. No interventions were performed. Results Demographics and induction and intubation documentation were reviewed for 21 patients who underwent thoracic surgery and one-lung ventilation with placement of a double lumen endobronchial tube using a novel combined video laryngoscopy and flexible fiberoptic bronchoscope approach. First pass success using the combined approach was 86% (18/21). The five patients with an anticipated difficult airway had successful double lumen endobronchial tube placement on the first attempt. There were no instances of desaturation during double lumen endobronchial tube placement. No airway complications related to double lumen endobronchial tube placement were recorded. Conclusion Use of a combined approach employing video laryngoscopy and a flexible fiberoptic bronchoscope may represent a reliable alternative approach to placement of double lumen endobronchial tubes.

A double-lumen tube or bronchial blocker positioning using flexible bronchoscopy for lung isolation and one-lung ventilation requires specific technical competencies. Training to acquire and retain such skills remains a challenge in thoracic anesthesia. Recent technological and innovative developments in the field of simulation have opened up exciting new horizons and possibilities. In this narrative review, we examine the latest development of existing training modalities while investigating, in particular, the use of emergent techniques such as virtual reality bronchoscopy simulation, virtual airway endoscopy, or the preoperative 3D printing of airways. The goal of this article is, therefore, to summarize the role of existing and future applications of training models/simulators and virtual reality simulators for training flexible bronchoscopy and lung isolation for thoracic anesthesia.

Left-sided double-lumen tube (LDLT) is commonly used to achieve one lung isolation in most thoracic surgical procedures. Traditionally, the LDLT is blindly placed using direct or video laryngoscopy. In this brief report, we highlight the importance of using our novel insertion depth formula to predict the appropriate LDLT insertion depth and demonstrate the current evidence supporting the efficacy of the formula. Also, we will discuss two relatively new devices of LDLTs: one with an embedded camera at the distal end of the tracheal lumen and the other with a carinal cuff between the bronchial cuff and the tracheal lumen in reducing the incidence of too deep inserted LDLT. We advocate that using our novel formula and these two new devices may reduce but not eliminate the need for FOB to check the insertion depth of LDLT. [ABSTRACT FROM AUTHOR]

Innovations and challenges for lung separation or isolation have evolved during the last few years. In this chapter, we present the up-to-date, robust evidence available during the previous five years supporting the positions of the different devices, techniques, and tricks for their use in adult and pediatric patients undergoing various thoracic surgical interventions. Additionally, we presented an update on lung isolation in patients with airway difficulty and the suggested training level to master these techniques. [ABSTRACT FROM AUTHOR]

Failure to provide one-lung ventilation can prohibit minimally invasive thoracic surgeries. Strategies for one-lung ventilation include double-lumen endotracheal tubes or endobronchial blockers, but rarely both. Inability to provide lung isolation after double-lumen endotracheal tube placement requires troubleshooting and sometimes the use of extra equipment. This case describes using a unique Y-shaped endobronchial blocker placed through a left-sided double-lumen endotracheal tube after failure to achieve lung isolation with a double-lumen endotracheal tube alone.

A recent trend in postoperative analgesia for lung cancer surgery relies on regional nerve blocks with decreased opioid administration. Our study aims to critically assess the continuous ultrasound-guided erector spinae plane block (ESPB) at our institution and compare it to a standard regional anesthetic technique, the intercostal nerve block (ICNB).

VivaSightTM Video-Double Lumen Tube (V-DLT) is a new DLT with an embedded camera. It is connected to a monitor that continuously demonstrates the position of the tube relative to that of the carina. It is very effective for the rapid placement of the DLT. Additionally, it recognizes tube repositioning and maintains one-lung ventilation. There is no risk of contamination because it is disposable. Herein, we present the case of a patient where simultaneous visualization allowed the detection of an iatrogenic cuff rupture in a patient intubated with VivaSight V-DLT and the challenging anesthetic management following air leakage during remainder of the procedure.

To clarify the influence of lower tidal volume (4-7 mL/kg) compared with higher tidal volume (8-15 mL/kg) during one-lung ventilation (OLV) on gas exchange and postoperative clinical outcome. Meta-analysis of randomized trials. Thoracic surgery. Patients receiving OLV. Lower tidal volume during OLV. Primary outcome was PaO 2 - to-the oxygen fraction (PaO 2 /FIO 2) ratio at the end of the surgery, after the reinstitution of two-lung ventilation. Secondary endpoints included perioperative changes in PaO 2 /FIO 2 ratio and carbon dioxide (PaCO 2) tension, airway pressure, the incidence of postoperative pulmonary complications, arrhythmia, and length of hospital stay. Seventeen randomized controlled trials (1,463 patients) were selected. Overall analysis showed that the use of low tidal volume during OLV was associated with a significantly higher PaO 2 /FIO 2 ratio 15 minutes after the start of OLV and at the end of surgery (mean difference 33.7 mmHg [p = 0. 02] and mean difference 18.59 mmHg [p < 0.001], respectively). The low tidal volume also was associated with higher PaCO 2 values 15 minutes and 60 minutes after the start of OLV and with lower airway pressure, which was maintained during two-lung ventilation after surgery. Moreover, the application of lower tidal volume was associated with fewer postoperative pulmonary complications (odds ratio 0.50; p < 0.001) and arrhythmias (odds ratio 0.58; p = 0.009), with no difference in length of hospital stay. The use of lower tidal volume, a component of protective OLV, increases the PaO 2 /FIO 2 ratio, reduces the incidence of postoperative pulmonary complications, and should be considered strongly in daily practice.

Abstract Background The double-lumen tube (DLT) is an essential equipment for thoracic anesthesia and the precise position of DLT placement is particularly important for anesthesia and surgery. However, the incidence of DLT malposition remains high and it leads to lung isolation failure and hypoxemia during one-lung ventilation. This trial aims to explore the clinical application and efficacy of intubation in the lateral position under general anesthesia induction to reduce the incidence of DLT malposition in patients undergoing unilateral video-assisted thoracic surgery (VATS). Methods In this prospective, single-center, parallel group, randomized, controlled trial, we will recruit 108 patients, aged 18–80 years, scheduled for elective unilateral VATS with DLT intubation under general anesthesia, and they will be randomly assigned to two groups: a lateral DLT intubation group (group L) and a conventional supine DLT intubation group (group C). The left-sided DLT will be used to intubate in patients of both groups. The position of DLT will be confirmed and adjusted by using the fiberoptic bronchoscopy (FOB). The primary outcome is the incidence of DLT malposition observed via the FOB, and the secondary outcomes include the time of intubation, the frequency and duration of re-adjustments of DLT placement under FOB, whether to re-intubate, intraoperative vital signs, and postoperative recovery. Discussion Accurate DLT positioning is crucially important for thoracic surgery, but the incidence of DLT malposition is still high in the present clinical practice of thoracic anesthesia. This trial aims to investigate whether lateral DLT intubation can reduce the incidence of DLT malposition, with more stable intraoperative vital signs and less postoperative complications.

Extensive preventive strategies in the perioperative period are popular worldwide. Novel “prehabilitation” approaches are being defined for every individual surgical discipline. With intention to reduce perioperative morbidity, “prehabilitation” was developed to increase “physical wellness” considering exercise capacity, nutritional status, and psychological support. Thus, prehabilitation could be well-suited for patients undergoing lung cancer surgery. Theoretically, improving physical condition may increase the chances of having a better post-operative course, especially among frail patients. In this review, we describe the concept of prehabilitation with possible benefits, its role in the Enhanced Recovery After Surgery protocols, and its potential for the future.

Cardiac and thoracic surgery have been connected to high perioperative opioid use for a long time. With increasing knowledge of regional anesthesia in the thoracic region, thoracic nerve blocks have become supplemental methods of analgesia. As part of multimodal analgesia, they are important factors of enhanced recovery after surgery and contribute to a diminished opioid use. Myofascial nerve blocks are more superficial than the classic thoracic epidural anesthesia or paravertebral block and are therefore safer for use in anticoagulated patients. In this article, we present a number of thoracic blocks; the paraneuraxial paravertebral block; the myofascial plane blocks which are the retrolaminar block, the erector spinae plane block, the serratus anterior plane block, the pectoral nerves I and II block, the transversus thoracis plane block and the parasternal intercostal nerve block; the perineural intercostal nerve block and also local anesthetic infusion by a wound catheter. We conclude with local experience from a cardiac and thoracic surgical center. [ABSTRACT FROM AUTHOR]

Anthropometric measurements like height and gender have been frequently found to be inaccurate in prediction of size of double lumen tube (DLT). A tracheal ultrasonography (TUS) is a technique that can be used to predict the size of DLT and its correct placement for lung isolation. We aim to check the accuracy of ultrasound over clinical methods. This prospective study included 68 patients undergoing elective thoracic surgery requiring one-lung ventilation (OLV) with DLT. The groups were assessed for the size of DLT by either anthropometric measurement using height and gender (Group C) or ultrasound method (Group U). Further, the accuracy of placement of DLT was assessed through, either lung auscultation in group C or various ultrasonographic and ventilatory parameters such as lung isolation in the first attempt (lung sliding and lung pulse sign), oxygenation status and peak airway pressure, in group U. Surgeon satisfaction score was also compared in both the groups. The accuracy of predicted DLT size between Group C and Group U was statistically significant (p=0.044). In Group C, 56% of patients showed a mismatch between the predicted DLT size and the actual size required, while in Group U, the mismatch was only 32.4%. The accuracy of DLT placement through group C was 41% as compared to 79% in Group U. Surgeon satisfaction score was also significantly higher in Group U as compared to Group C (p=0.0028). Thus, our study suggests that tracheal and chest ultrasonography for DLT size selection and placement for lung isolation is superior to clinical methods.

Central airway obstruction due to tracheal tumors presents unique challenges to the anesthesiologist. We present the case of a 44-year-old male taken to the OR for biopsy and resection of an undiagnosed tracheal mass. Intraoperative management was complicated by bleeding and significant hemodynamic instability, necessitating rapid surgical and anesthetic intervention. This ultimately led to abortion of surgical resection. Pathologic examination revealed a primary tracheal plasmacytoma, a rare type of tracheal tumor. Here, we describe anesthetic and hemodynamic considerations for a tracheal plasmacytoma. We discuss the approach to airway management in variable intrathoracic tracheal obstruction and the unpredictability of tracheal tumors. [ABSTRACT FROM AUTHOR]

Objective: Pectus excavatum (PE) repair is burdened by severe postoperative pain. This retrospective study aimed to determine whether the analgesic effect of ultrasound-guided erector spinae plane block (ESPB) plus standard intravenous analgesia (SIVA) might be superior to SIVA alone in pain control after PE surgical repair via Ravitch or Nuss technique. Design: A retrospective cohort study. Setting: At a university hospital. Participants: All participants were scheduled for surgical repair of PE. Interventions: From January 2017 to December 2019, all patients who received ESPB plus SIVA or SIVA alone were investigated retrospectively. A 2:1 propensity-score matching analysis considering preoperative variables was used to compare analgesia efficacy in 2 groups. All patients received a 24-hour continuous infusion of tramadol, 0.1 mg/kg/h, and ketorolac, 0.05 mg/kg/h, via elastomeric pump, and morphine, 2 mg, intravenously as a rescue drug. The ESPB group received preoperative bilateral ESPB block. Postoperative pain, reported using a numerical rating scale at 1, 12, 24, and 48 hours after surgery; the number of required rescue doses; total postoperative morphine milligram equivalents consumption; and the incidence of postoperative nausea and vomit were analyzed. Measurement and Main Results: A total of 105 patients were identified for analysis. Propensity-score matching resulted in 38 patients in the SIVA group and 19 patients in the ESPB group. Postoperative pain, the number of rescue doses, and postoperative nausea and vomit incidences were lower in the ESPB group (p < 0.005). Conclusions: Erector spinae plane block may be an effective option for pain management after surgical repair of PE as part of a multimodal approach. This study showed good perioperative analgesia, opioid sparing, and reduced opioid-related adverse effects. [ABSTRACT FROM AUTHOR]

Pulmonary aspergillosis is a life-threatening condition, especially for individuals with predisposing factors such as prior tuberculosis, smoking, and immune impairment. This case report describes the management of a 33-year-old male with a history of cured tuberculosis and active pulmonary aspergillosis who developed hemorrhagic shock following severe hemoptysis. Initial management included blood transfusion and the administration of tranexamic acid. Surgical prehabilitation was performed, and the patient underwent bilobectomy. Post-surgery, the patient developed respiratory failure due to a bronchopleural fistula, which was surgically repaired. The patient was managed in the intensive care unit (ICU) and subsequently discharged in good health. This case highlights the complexity of managing severe hemoptysis and its complications, and the importance of early multidisciplinary intervention and preoperative optimization., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

For decades, the management of symptomatic cholelithiasis in high surgical risk patients has remained contentious. Cholecystectomy has become firmly established as a procedure of choice in the management of symptomatic cholelithiasis. The procedure usually necessitates general anesthesia and endotracheal intubation to prevent aspiration and respiratory embarrassment secondary to the induction of pneumoperitoneum. Open cholecystectomy (OC) usually necessitates general anesthesia and endotracheal intubation to prevent aspiration and respiratory embarrassment. We report our preliminary experience with open cholecystectomy using thoracic anesthesia in patients with cardiac failure and with previous history of smoking. A 78-year-old mal (weight 81 kg, height 176 cm) with abdominal pain applied to the emergency department. After general surgery and infectious disease consultations, he was admitted to the intensive care unit because of high infection parameters and general condition disorder. He had a history of frequent pain at the right hypochondriac region with ultrasonography documented calculi in the gallbladder for two years and heart failure. With the patient at the right lateral decubitus position, EA was performed with a 18-G thoracic catheter inserted 4cm towards the cephalad-direction from T7/T8 successfully. After completion of the surgical procedure, the thoracic catheter was removed, and the patient was shifted to the post-anesthesia care unit (PACU) for further observation. The patient remained hemodynamically stable and comfortable during the 1 hour at PACU. In this case report, we wanted to demonstrate the management of an emergency case with epidemic anesthesia, with a general condition of poor heart failure and septic shock. [ABSTRACT FROM AUTHOR]

Background: While many hospitals in Germany perform thoracic surgery, anesthetic techniques and methods that are actually used are usually only known for individual departments. This study describes the general anesthetic management of three typical thoracic surgical procedures across multiple institutions. Material and methods: The German Thoracic Registry recorded 4614 patients in 5 institutions between 2016 and 2019. Hospitals with a minimum number of more than 50 thoracic procedures per year are eligible for inclusion in the registry. To analyze the anesthetic management, a matching process yielded three comparable patient groups (n = 1506) that differed solely in the surgical procedure. Three surgical procedures with varying degrees of invasiveness were selected: Group A = video-assisted thoracoscopic surgery (VATS) with wedge resection, group B = VATS with lobectomy, group C = open thoracotomy. Statistical analysis was performed descriptively using relative and absolute frequencies. Dichotomous variables were compared using the χ2-test. Results: The study enrolled patients with a median age of 65.6 years. The mean value of the American Society of Anesthesiologists (ASA) classification was 2.8. One lung ventilation was most commonly performed (group A = 98.2%, group B = 99.4%, group C = 98.0%) with double lumen tubes (DLT). Bronchial blockers (group A = 0.2%, group B = 0.4%, group C = 0%) were rarely used. Primary bronchoscopy was used to control double lumen tubes after insertion in the majority of cases (group A = 77.5%, group B = 73.1%, group C= 79.7%). Continuous positive airway pressure (CPAP, group A = 1.2%, group B = 1.4%, group C = 5.1%) and jet ventilation (group A = 1.6%, group B = 1.6%, group C = 1.4%) were rarely used intraoperatively. In group C, the administration of a vasopressor was also more frequently required (group A = 59.9%, group B = 77.8%, group C = 86%). A central venous catheter was established in 30.1% of all patients in group A, 39.8% in group B and 73.3% in group C. Patients in group A received an arterial catheter less frequently (71.7%) when compared to groups B (96.4%) and C (95.2%). Total intravenous anesthesia with propofol was used in most patients (group A = 67.7%, group B 61.6%, group C 75.7%). Propofol supplemented by volatile anesthetics was used less frequently (group A = 28.5%, group B = 35.5%, group C = 23.7%). With increasing invasiveness of the surgical procedure, placement of an epidural catheter was preferred (group A = 18.9%, group B = 29.5%, group C = 64.1%). Paravertebral catheters (group A = 7.6%, group B = 4.4%, group C = 4.8%) or a single infiltration of the paravertebral space were performed less frequently (group A = 7.8%, group B = 17.7%, group C = 11.6%). Postoperatively, some patients (3.4–25.7%) were transferred to the general ward. The largest proportion of patients transferred to a general ward underwent less invasive thoracic procedures (group A). When the extent of resection was greater (group B and group C) patients were mostly transferred to an intermediate care unit (IMC) or an intensive care unit (ICU). The insertion of invasive catheters was neither associated with the patients' ASA classification nor preoperative pathologic pulmonary function. Conclusion: Our data indicate that less invasive thoracic operations are associated with a reduction of invasive anesthetic procedures. As the presented data are descriptive, further studies are required to determine the impact of invasive anesthetic procedures on patient-related outcomes. This evaluation of the anesthetic management in experienced thoracic anesthesiology departments represents the next step towards establishing national quality standards and promoting structural quality in thoracic anesthesia.

Test the hypothesis that one-lung ventilation with variable tidal volume improves intraoperative oxygenation and reduces postoperative pulmonary complications after lung resection. Constant tidal volume and respiratory rate ventilation can lead to atelectasis. Animal and human ARDS studies indicate that oxygenation improves with variable tidal volumes. Since one-lung ventilation shares characteristics with ARDS, we tested the hypothesis that one-lung ventilation with variable tidal volume improves intraoperative oxygenation and reduces postoperative pulmonary complications after lung resection. Randomized trial. Operating rooms and a post-anesthesia care unit. Adults having elective open or video-assisted thoracoscopic lung resection surgery with general anesthesia were randomly assigned to intraoperative ventilation with fixed (n = 70) or with variable (n = 70) tidal volumes. Patients assigned to fixed ventilation had a tidal volume of 6 ml/kgPBW, whereas those assigned to variable ventilation had tidal volumes ranging from 6 ml/kg PBW ± 33% which varied randomly at 5-min intervals. The primary outcome was intraoperative oxygenation; secondary outcomes were postoperative pulmonary complications, mortality within 90 days of surgery, heart rate, and SpO 2 /FiO 2 ratio. Data from 128 patients were analyzed with 65 assigned to fixed-tidal volume ventilation and 63 to variable-tidal volume ventilation. The time-weighted average PaO 2 during one-lung ventilation was 176 (86) mmHg in patients ventilated with fixed-tidal volume and 147 (72) mmHg in the patients ventilated with variable-tidal volume, a difference that was statistically significant (p < 0.01) but less than our pre-defined clinically meaningful threshold of 50 mmHg. At least one composite complication occurred in 11 (17%) of patients ventilated with variable-tidal volume and in 17 (26%) of patients assigned to fixed-tidal volume ventilation, with a relative risk of 0.67 (95% CI 0.34–1.31, p = 0.24). Atelectasis in the ventilated lung was less common with variable-tidal volumes (4.7%) than fixed-tidal volumes (20%) in the initial three postoperative days, with a relative risk of 0.24 (95% CI 0.01–0.8, p = 0.02), but there were no significant late postoperative differences. No other secondary outcomes were both statistically significant and clinically meaningful. One-lung ventilation with variable tidal volume does not meaningfully improve intraoperative oxygenation, and does not reduce postoperative pulmonary complications. • Variable tidal volume ventilation improves oxygenation in animals and humans with acute respiratory distress syndrome. • We compared oxygenation and pulmonary complications in patients randomized to one-lung ventilation with variable or fixed tidal volumes • Ventilation with variable tidal volume did not improve oxygenation or reduce postoperative pulmonary complications.

Anesthesiology has always been one of the most important components of the multidisciplinary perioperative approaches, which is also valid for ERAS. There are several guidelines published on the enhanced recovery after thoracic surgery (ERATS). This article focuses on the “official” ERATS protocols of a joint consensus of two different societies. Regarding thoracic anesthesia, there are some challenges to be dealt with. The first challenge, although there is a large number of studies published on thoracic anesthesia, only a very few of them have studied the overall outcome and quality of recovery; and only few of them were powered enough to provide sufficient evidence. This has led to the fact that some components of the protocol are debatable. The second challenge, the adherence to individual elements and the overall compliance are poorly reported and also hard to apply even in the best organized centers. This article explains and discusses the debatable viewpoints on the elements of the ERATS protocol published in 2019 aiming to achieve a list for the future steps required for a more effective and evidence-based ERATS protocol.

Before the advancement of anesthesia techniques in the mid-1930s, chest operations were short and difficult. Anesthesia during thoracic surgery is in itself very demanding and complicated to work with and represents a real challenge for the anesthesiologist. In order to perform the operation smoothly in patients whose respiratory reserve has already been reduced, it is necessary to exclude the lung that is being operated on and to isolate the lung that is ventilated during the surgical intervention. Double lumen tubes and endobronchial blockers are used to secure the airway and to achieve collapse and unilateral ventilation. Fiberoptic bronchoscopy is the gold standard in the world of modern thoracic anesthesia for checking the position of a double lumen tube and endobronchial blocker. [ABSTRACT FROM AUTHOR]

Abstract Background There is a major paradigm shift for intraoperative mechanical ventilator support by the introduction of lung protective ventilation strategies to reduce postoperative pulmonary complications and improve overall clinical outcomes in non-thoracic surgeries. However, there is currently a lack of standardized practice guideline for lung protection during thoracic surgeries that require one-lung ventilation (OLV). This study aimed to collect the expert opinions of the thoracic anesthesiologists in perioperative care for OLV surgery in Taiwan. Methods This prospective cross-sectional study was undertaken in 16 tertiary hospitals in Taiwan from January to February 2019. A structured survey form was distributed across the participating hospitals and the thoracic anesthesiologists were invited to complete the form voluntarily. The survey form consisted of three parts, including the basic information of the institutional anesthesia care standards, ventilatory settings for a proposed patient receiving OLV surgery and expert opinions on OLV. Results A total of 71 thoracic anesthesiologists responded to the survey. Double-lumen tubes are the most commonly used (93.8%) airway devices for OLV. The most commonly recommended ventilator setting during OLV is a tidal volume of 6–7 ml/kg PBW (67.6%) and a PEEP level of 4–6 cmH2O (73.5%). Dual controlled ventilator modes are used by 44.1% of the anesthesiologists. During OLV, high oxygen fraction (FiO2 > 0.8) is more commonly supplemented to achieve an oxygen saturation higher than 94%. The consensus of anesthesiologists on the indices for lung protection in thoracic surgery is considerably low. Large majority of the anesthesiologists (91.5%) highly recommend that an international clinical practice guideline on the protective lung ventilation strategy for thoracic anesthesia should be established. Conclusions This study found that the thoracic anesthesiologists in Taiwan share certain common practices in ventilator support during OLV. However, they are concerned about the lack of fundamental clinical evidences to support the beneficial outcomes of the current lung protective strategies applicable to OLV. Large-scale trials are needed to form an evidence-based clinical practice guideline for thoracic anesthesia.

The novel coronavirus pandemic has radically changed the landscape of normal surgical practice. Lifesaving cancer surgery, however, remains a clinical priority, and there is an increasing need to fully define the optimal oncologic management of patients with varying stages of lung cancer, allowing prioritization of which thoracic procedures should be performed in the current era. Healthcare providers and managers should not ignore the risk of a bimodal peak of mortality in patients with lung cancer; an imminent spike due to mortality from acute coronavirus disease 2019 (COVID-19) infection, and a secondary peak reflecting an excess of cancer-related mortality among patients whose treatments were deemed less urgent, delayed, or cancelled. The European Association of Cardiothoracic Anaesthesiology and Intensive Care Thoracic Anesthesia Subspecialty group has considered these challenges and developed an updated set of expert recommendations concerning the infectious period, timing of surgery, vaccination, preoperative screening and evaluation, airway management, and ventilation of thoracic surgical patients during the COVID-19 pandemic.

Re-expansion pulmonary edema is a potentially life-threatening situation following thoracic surgery of a compromised lung. We report the case of a 24-year-old female scheduled for a resection of a large intrathoracic desmoid tumor that presented with re-expansion pulmonary edema at the conclusion of her surgery and discuss the clinical presentation, mechanism and predictors of this entity and review similar cases reported in the literature.

Background: The incidence of hypoxemia during one-lung ventilation (OLV) is as high as 10%. It is also partially determined by the distribution of perfusion. During thoracic surgery, different body positions are used, such as the supine, semilateral, lateral, and prone positions, with such positions potentially influencing the distribution of perfusion. Furthermore, hypovolemia can impair hypoxic vasoconstriction. However, the effects of body position and hypovolemia on the distribution of perfusion remain poorly defined. We hypothesized that, during OLV, the relative perfusion of the ventilated lung is higher in the lateral decubitus position and that hypovolemia impairs the redistribution of pulmonary blood flow.Methods: Sixteen juvenile pigs were anesthetized, mechanically ventilated, submitted to a right-sided thoracotomy, and randomly assigned to one of two groups: (1) intravascular normovolemia or (2) intravascular hypovolemia, as achieved by drawing ~25% of the estimated blood volume (n = 8/group). Furthermore, to mimic thoracic surgery inflammatory conditions, Escherichia coli lipopolysaccharide was continuously infused at 0.5 μg kg−1 h−1. Under left-sided OLV conditions, the animals were further randomized to one of the four sequences of supine, left semilateral, left lateral, and prone positioning. Measurements of pulmonary perfusion distribution with fluorescence-marked microspheres, ventilation distribution by electrical impedance tomography, and gas exchange were then performed during two-lung ventilation in a supine position and after 30 min in each position and intravascular volume status during OLV.Results: During one-lung ventilation, the relative perfusion of the ventilated lung was higher in the lateral than the supine position. The relative perfusion of the non-ventilated lung was lower in the lateral than the supine and prone positions and in semilateral compared with the prone position. During OLV, the highest arterial partial pressure of oxygen/inspiratory fraction of oxygen (PaO2/FIO2) was achieved in the lateral position as compared with all the other positions. The distribution of perfusion, ventilation, and oxygenation did not differ significantly between normovolemia and hypovolemia.Conclusions: During one-lung ventilation in endotoxemic pigs, the relative perfusion of the ventilated lung and oxygenation were higher in the lateral than in the supine position and not impaired by hypovolemia.

Surgical resection and tracheal reconstruction are the most effective treatment options for airway stenosis. Tracheal surgery is challenging and requires a multidisciplinary approach and a highly specialized team of anesthesiologists and thoracic surgeons that are “sharing the airways”. Several airway management tools, different devices, and various approaches can be required to ensure ventilation and gas exchange. We describe the case of a patient affected by tight tracheal stenosis, submitted to tracheal resection and reconstruction via combined cervicotomy and sternotomy surgical approach. Airway management was successfully performed by i-gel® (Intersurgical, UK) supraglottic device.

Double lumen tubes (DLTs) are most commonly used to achieve one lung ventilation (OLV) in most thoracic surgical procedures unless contraindicated. Left-sided DLT (LDLT) is most commonly used nowadays for most thoracic surgical procedures. Though, the use of LDLT dates long back in history, two clinical and technical issues are yet to be resolved. The first issue is the ideal size of DLT which is defined as that which provides near-complete seal of the bronchial lumen without cuff inflation. There are no guidelines in literature which help in selecting the size of DLT. However, general consensus among thoracic anesthesiologists recommends the use of smaller sizes to avoid airway trauma. In our practice and for the last few years, we are using smaller size LDLT 35 F for females and 37 F for males with minimal airway trauma and had encouraging results. The second issue is the insertion depth of the LDLT. We have introduced a height-based formula to predict the insertion depth of LDLT with encouraging results. However, even with the use of the formula, we still recommend the use of fiberoptic bronchoscopic confirmation method for final positioning of the LDLT.

To assess if there is a difference in the repositioning rate of the EZ-Blocker versus a left-sided double-lumen endobronchial tube (DLT) in patients undergoing thoracic surgery and one-lung ventilation. Prospective, randomized. Single center, university hospital. One hundred sixty-three thoracic surgery patients. Patients were randomized to either EZ-Blocker or a DLT. The primary outcome was positional stability of either the EZ-Blocker or a left-sided double-lumen endobronchial tube, defined as the number of repositionings per hour of surgery and one-lung ventilation. Secondary outcomes included an ordinal isolation score from 1 to 3, in which 1 was poor, up to 3, which represented excellent isolation, and a visual analog postoperative sore throat score (0-100) on postoperative days (POD) one and two. Rate of repositionings per hour during one-lung ventilation and surgical manipulation in left-sided cases was similar between the two devices: 0.08 ± 0.15 v 0.11 ± 0.3 (p = 0.72). In right-sided cases, the rate of repositioning was higher in the EZ-Blocker group compared with DLT: 0.38 ± 0.65 v 0.09 ± 0.21 (p = 0.03). Overall, mean isolation scores for the EZ-Blocker versus the DLT were 2.76 v 2.92 (p = 0.04) in left-sided cases and 2.70 v 2.83 (p = 0.22) in right-sided cases. Median sore throat scores for left sided cases were 0 v 5 (p = 0.13) POD one and 0 v 5 (p = 0.006) POD two for the EZ-Blocker and left-sided DLT, respectively. For right-sided procedures, the positional stability of the EZ-Blocker is inferior to a DLT. In left-sided cases, the rate of repositioning for the EZ-Blocker and DLT are not statistically different.

Background: Accurate positioning of a right-sided double-lumen tube is essential but challenging due to the location and the potential obstruction of the right upper lobe bronchus. Fiberoptic bronchoscopy is, therefore, necessary but requires a specific training period for the anesthesiologist and might not always be available. Objective: We describe an original backup technique to assess the correct placement of these tubes in cases a fiberopetic bronchoscopy is lacking. Design: Prospective pilot feasibility study with 10 adult patients scheduled for a left thoracic surgery. Setting: Operating theater in a universitary hospital. Materials and Methods: The new technique uses a fluoroscopy and an adult central venous catheter wire. The time needed to perform the new technique, its success rate and its efficacy in properly exclude the left lung were evaluated. Any oxygen desaturation episode (SpO2

In recent years, the concept of "Perioperative Medicine" has been evolved to a more concrete and sophisticated approach called "Enhanced Recovery After Surgery" (ERAS). ERAS has been first introduced in colorectal surgery by a dedicated leading ERAS® society, ERAS-criteria has been subsequently extended into several types of surgery, including thoracic surgery. Anesthesiology has always been one of the most important components of the multidisciplinary perioperative approaches, which is also valid for ERAS. There are several guidelines published on the enhanced recovery after thoracic surgery (ERATS). This article focuses on the "official" ERATS protocols of a joint consensus of two different societies. Regarding thoracic anesthesia, there are some challenges to be dealt with. The first challenge, although there is a large number of studies published on thoracic anesthesia, only a very few of them have studied the overall outcome and quality of recovery; and only few of them were powered enough to provide sufficient evidence. This has led to the fact that some components of the protocol are debatable. The second challenge, the adherence to individual elements and the overall compliance are poorly reported and also hard to apply even in the best organized centers. This article explains and discusses the debatable viewpoints on the elements of the ERATS protocol published in 2019 aiming to achieve a list for the future steps required for a more effective and evidence-based ERATS protocol.

The year 2020 was a monumental year in medicine, and this review focuses on selected articles for cardiothoracic anesthesiologists and perioperative physicians involved in the care of heart and lung transplant patients. In the field of lung transplantation, significant strides were made in our knowledge of risk stratification during the preoperative assessment of potential recipients, perioperative transfusion medicine, and the administration of coagulation factor concentrates. In addition, variations in perioperative management and outcomes between institutions were studied across an assortment of metrics regarding lung transplantation, including case volumes and anesthetic practices. Transitioning to topics in the field of heart transplantation, consideration was given to recipients with adult congenital heart disease, and separately, approaches to expanding the donor pool through donation after circulatory death. With regard to preoperative support, outcomes for the total artificial heart as well as the MitraClip as bridges to transplantation were published. [ABSTRACT FROM AUTHOR]

The aim of the survey was to understand the contemporary thoracic anesthesia practice in India. A prospective questionnaire–based survey. The survey was conducted at the Annual Conference of the Indian Association of Cardiovascular and Thoracic Anesthesiologists 2018 (IACTACON-2018). After the conference, the questionnaire was distributed again to the conference participants electronically to increase the response rate. Anesthesiologists from India attending IACTACON-2018. Hard copies of a validated questionnaire (n = 430) were distributed among Indian anesthesiologists attending IACTACON 2018. The questionnaire included 17 questions pertaining to preanesthesia checkup, lung isolation devices, intraoperative management, postoperative analgesia, and infrastructure available at their institutions. Following the conference, the survey was continued online by sending the link of the online survey to all registered participants (n = 421) from India, taking care to avoid duplication of responses. Collected data were analyzed using frequency distributions and chi-square tests. Total responses were 166 (110 hardcopies and 56 online responses) of 430, with the response rate being 38.6%. A double-lumen tube (DLT) was the most commonly preferred for lung isolation (160/166: 96.4%). Nearly 55% of anesthesiologists preferred auscultation for confirmation of DLT, as 38% of anesthesiologists reported unavailability of the pediatric bronchoscope. Nearly 80% of anesthesiologists were compliant with the principles of protective one-lung ventilation. Preference for inhalation anesthetic agents during one-lung ventilation, use of restrictive intravenous fluids, and regional blocks for postoperative analgesia commonly were followed by the Indian anesthesiologists. Despite the challenges offered by limited resources, the practice of thoracic anesthesia in India is at par with the standards followed across the world. [ABSTRACT FROM AUTHOR]

Background: In the field of thoracic anesthesia, it is well-established practice that the insertion depth of left-sided double-lumen tube (LDLT) is achieved after checking its position via fiberoptic bronchoscopy (FOB). Several studies have shown positive correlation between body height (BH) and the optimal insertion depth of a LDLT. Each of these studies has developed a formula for proper insertion depth of the LDLT. In this study, we prospectively studied our patients whose tracheas were intubated correctly with LDLT using FOB confirmation and examined the optimal insertion depth of LDLT aiming at finding a formula suitable for our patients. Methods: After obtaining the institutional review board approval of College of Medicine Research Centre, King Saud University, we recruited 41 adult patients who underwent thoracic surgery with one-lung ventilation (OLV). The study included patients whose procedure required placement of a LDLT. The optimal insertion depth of the LDLT was confirmed using FOB. The following variables were recorded, the patient's sex, age, BH, and the final correct insertion depth of the LDLT (cm) measured from the corner of the mouth. The results of LDLT insertion depth in our study were compared to another published five studies. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) version 22 software (SPSS Inc., Chicago, IL, USA). Results: Positive correlation was found between BH (cm) and insertion depth of LDLT (cm) since r = 0.744 (P < 0.05). Also, positive correlation was found between the LDLT size (Fr) and insertion depth of LDLT (cm) since r = 0.792 (P < 0.05) where r is Pearson's correlation coefficient. By fit curve (Curve Estimation), we were able to get the predicted equation for our cases as follow: the insertion depth of LDLT (cm) =0.249 × (BH)0.916 with significant correlation to the other five formulae (P < 0.05). Conclusion: In the present study we have obtained a novel formula to predict the insertion depth of LDLT. Currently we are conducting a verification study on a larger sample size to attest its validity. However at this stage and till the results are released we cannot judge on it. We believe time will tell about the validity of our formula for our patients.

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. [ABSTRACT FROM AUTHOR]

The global importance of the anesthetic protection in thoracic surgery belongs to the methods of anesthesia and respiratory support, which ensure the optimal level of gas exchange. The paper presents the results of the study of factors and patterns that affect the efficiency of gas exchange in the lungs under anesthesia based on inhaled halogen-containing anesthetics. The aim of the study is to determine the capabilities of the modern inhaled anesthetics (desflurane, sevoflurane, isoflurane) to affect the effectiveness of gas exchange in the lungs. Materials and methods: the study included 58 patients of II-IV degree of risk (ASA). Thoracotomy or innovative thoracoscopic access to the surgical field was done. The main anesthetic: desflurane (DF) - 23 patients, sevoflurane (SF) -16 patients, isoflurane (IF) - 19 patients. Were studied the indicators of systemic, pulmonary, intracardiac hemodynamics with the pulmonary thermodilution (PT) method with the analysis of gas exchange and lung metabolism, acid-base balance, gas and electrolytic balance of arterial and mixed venous blood. Stages of the study: Stage 1 - after induction into anesthesia, under conditions of ventilation of both lungs (ALV-1); Stage 2 – in conditions of surgical pneumothorax and artificial one-lung ventilation OLV); 3 and 4 stages – the main stage of the operation with OLV 60, 80-120 minutes; Stage 5 – the end of the main stage of the operation with both lungs ventilation (ALV-2). Results: There were identified the influence of DF and SF on gas exchange blood flow in all variants of respiratory regimes (pre- and post-capillary resistance). A significant difference in the total peripheral resistance at stages 1, 3 and 4 with DF was comparable to the IF effect. A higher pump coefficient of the right ventricle was received with DF at all stages of the study, as well as a smaller amount of physiological dead space. Conclusion: We assume that the systemic vasodilating effect of desflurane extends to the bronchial blood flow, as an integral part of the systemic circulation, as well as to vessels of extracapillary perfusion. Simultaneously, in comparison with SF, a smaller amount of physiological dead space with DF indicates a larger area of the perfused gas exchange surface under conditions of OLV. A higher pump coefficient of the right ventricle with DF at all stages of the study is a sign of its cardioprotective effect. [ABSTRACT FROM AUTHOR]

• Thoracic anesthesiologists might be involved in the perioperative care of patients suspected to have or diagnosed COVID-19 who might undergo thoracic surgery during the acute or convalescence phases of the disease. • Caution should be exercised when securing the airway and performing lung separation (if required), through vigilant donning/doffing of personal protection equipment (PPE), planning ahead, team briefing, proper preparations, systematic approach, and debriefing. • Lung separation/isolation should be individualized using either bronchial blockers or double lumen tubes according to the patient's status and perioperative care plan. • Optimal PPE donning should be maintained during surgery and anesthesia. One lung ventilation could be challenging in this group of patients. • The anesthesiologists should discuss the feasibility of extubating the patient following thoracic surgery, and procedures for postoperative care and transferring the patient to the isolation wards or intensive care unit. 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. [ABSTRACT FROM AUTHOR]

The time needed to perform the new technique, its success rate and its efficacy in properly exclude the left lung were evaluated. Any oxygen desaturation episode (SpO2 <90%) was considered. The technique was performed by two anesthesiologists with different experience in thoracic anesthesia.Results: The success rate of our technique was 90%, which did not depend on the anesthesiologist's experience. The range of time to successfully place the tube in the dorsal decubitus position and subsequently in the right lateral decubitus position was respectively 1 min-6 min and 1 min-15 min. None of the patients presented any desaturation episodes.Conclusions: We describe an original, safe, and acceptable backup technique to properly insert right-sided double-lumen endobronchial tubes, whenever a fiberoptic bronchoscopy is not available. Moreover, this technique is easy enough to be performed by anesthesiologists with limited experience in thoracic anesthesia. [ABSTRACT FROM AUTHOR]

Publications of note from 2018 are reviewed for the cardiothoracic transplant anesthesiologist. Strategies to expand the availability of donor organs were highlighted, including improved donor management, accumulating experience with increased-risk donors, ex vivo perfusion techniques, and donation after cardiac death. A number of reports examined posttransplant outcomes, including outcomes other than mortality, with new data-driven risk models. Use of extracorporeal support in cardiothoracic transplantation was a prominent theme. Major changes in adult heart allocation criteria were implemented, aiming to improve objectivity and transparency in the listing process. Frailty and prehabilitation emerged as targets of comprehensive perioperative risk mitigation programs. [ABSTRACT FROM AUTHOR]
