New Insight into Laryngo-Tracheal Surgery: High-Flow Oxygen Therapy to Prevent Early Complications after Surgery.

BACKGROUND: Early post-operative airway management after laryngo-tracheal surgery is crucial. Acute respiratory failure due to glottis' edema may occur, requiring reintubation. This can prolong ventilatory assistance, jeopardizing anastomosis. To date, only judicious steroid administration and fluid management are available to avoid more invasive procedures. High-flow oxygen therapy (HFOT) is a noninvasive O2 support method providing humidification, warmed air, and Positive End-Expiratory Pressure (AIRVO2). No data about HFOT use to prevent early complications after laryngo-tracheal surgery are reported in the literature. METHODS: Between September 2020 and September 2022, 107 consecutive patients who underwent laryngo-tracheal surgery received HFOT (Group A). Data and long-term results were compared with those of 80 patients operated between September 2018 and August 2020 (Group B), when HFOT was not available. All patients were operated in a single center. No pre- or post-operative settings changed, except for HFOT introduction. We analyzed and compared the risk for "delayed" reintubation (unexpected reintubation within the first 24-48 h after extubating/laryngeal mask removal) in the two groups. RESULTS: No patients reported HFOT-related adverse events. The control group (B) presented "delayed" reintubation in 37% (p = 0.027), intensive care unit admission in 67% (p = 0.005) and longer hospital stay (p = 0.001) compared to the HFOT group (A). The minor complications' rate was 3% in both group and overall mortality was 0%. Re-stenosis was described in 4.6% of the HFOT group, without a statistically significant difference (p = 0.7006). CONCLUSIONS: Our study is the first to investigate HFOT use in patients undergoing laryngo-tracheal surgery, potentially representing a consistent innovation in the peri-operative management of these patients. With the limitation of a retrospective series, we would suggest HFOT use for preventing post-operative reintubation rate, possibly reducing ICU admissions and hospital stays.

Prehospital Blood Transfusion in Helicopter Emergency Medical Services: An Italian Survey.

OBJECTIVE: Hemorrhage remains the most common cause of preventable death after trauma. Prehospital blood product (PHBP) administration may improve outcomes. No data are available about PHBP use in Italian helicopter emergency medical services (HEMS). The primary aim of this survey was to establish the degree of PHBP used throughout Italy. The secondary aims were to evaluate the main indications for their use, the opinions about PHBPs, and users' experience. METHODS: The study group performed a telephone/e-mail survey of all 56 Italian HEMS bases. The questions concerned whether PHBPs were used in their HEMS bases, the frequency of transfusions, the PHBP used, and the perceived benefits. RESULTS: Four of 56 HEMS bases use PHBPs. Overall, 7% have prehospital access to packed red cells and only 1 to fresh plasma. In addition to blood product administration, 4 of 4 use tranexamic acid, and 3 of 4 also use fibrinogen. Seventy-five percent use PHBPs once a month and 25% once a week. The users' experience was that PHBPs are beneficial and lifesaving. CONCLUSION: Only 4 of 56 HEMS in Italy use PHBPs. There is an absolute consensus among providers on the benefit of PHBPs despite the lack of evidence on PHBP use.

New perspectives on tracheal resection for COVID-19-related stenosis: A propensity score matching analysis.

OBJECTIVE: The large number of patients with COVID-19 subjected to prolonged invasive mechanical ventilation has been expected to result in a significant increase in tracheal stenosis in the next years. The aim of this study was to evaluate and compare postoperative outcomes of patients who survived COVID-19 critical illness and underwent tracheal resection for postintubation/posttracheostomy tracheal stenosis with those of non-COVID-19 patients. METHODS: It was single-center, retrospective study. All consecutive patients with post-intubation/posttracheostomy tracheal stenosis who underwent tracheal resection from February 2020 to March 2022 were enrolled. A total of 147 tracheal resections were performed: 24 were in post-COVID-19 patients and 123 were in non-COVID-19 patients. A 1:1 propensity score matching analysis was performed, considering age, gender, body mass index, and length of stenosis. After matching, 2 groups of 24 patients each were identified: a post-COVID-19 group and a non-COVID group. RESULTS: No mortality after surgery was registered. Posttracheostomy etiology of stenosis resulted more frequently in post-COVID-19 patients (n = 20 in the post-COVID-19 group vs n = 11 in the non-COVID-19 group; P = .03), as well as intensive care unit admissions during the postoperative period (16 vs 9 patients; P = .04). Need for postoperative reintubation for glottic edema and respiratory failure was higher in the post-COVID-19 group (7 vs 2 postoperative reintubation procedures; P = .04). Postoperative dysphonia was observed in 11 (46%) patients in the post-COVID-19 group versus 4 (16%) patients in the non-COVID-19 group (P = .03). CONCLUSIONS: Tracheal resection continues to be safe and effective in COVID-19-related tracheal stenosis scenarios. Intensive care unit admission rates and postoperative complications seem to be higher in post-COVID-19 patients who underwent tracheal resection compared with non-COVID-19 patients.

A Practical Guide for Using the EZ-Blocker Endobronchial Blocker: Tips and Tricks After 10 Years of Experience.

The EZ-Blocker (EZB) is a "Y-shaped," semirigid endobronchial blocker used for lung isolation and one-lung ventilation during thoracic surgery. Like many medical tools, initial efforts to use this endobronchial blocker may prove challenging for the uninitiated. However, some tips and tricks can be applied fairly rapidly to aid the clinician in properly placing the device, and, furthermore, may help the clinician get the most out of this innovative device. This article focuses on some of the technical aspects of its placement that the authors have developed over time. Additionally, other facets and potential pitfalls are discussed that relate to intraprocedural issues that may sometimes arise when using this device. The following aspects of the EZB as a lung-isolation device are discussed: standard positioning techniques, alternative positioning techniques, use in pediatric patients, approaches to achieving exceptional lung isolation, advanced uses, and limitations and potential issues. Although some information was taken from the authors' rather extensive experience with using this endobronchial blocker, some of the relevant literature are also reviewed, with the goal of being to improve the reader's knowledge of the device and improve the likelihood of its successful placement. The underlying design of the EZB remains unique among commercially available bronchial blockers in improving positional stability. The Y-shaped conformation, however, can lead to challenges when positioning the device in some patients. Therefore, some very practical tips and tricks are provided to assist the clinician in correctly positioning the device and other hints to improve the quality of lung isolation and surgical conditions.

The safety of thoracic paravertebral block and erector spinae plane block in patients treated with anticoagulant or antiplatelet therapy. A narrative review of the evidence.

INTRODUCTION: The management of thoracic paravertebral block (TPVB) and erector spine plane block (ESPB) in patients treated with anticoagulant or antiplatelet therapy is based on limited clinical data, mostly from single case reports. Scientific societies and organizations do not provide strong detailed indications about the limitations of these regional anesthesia techniques in patients receiving antithrombotic therapy. This review summarizes evidence regarding TPVB and ESPB in patients under antithrombotic therapy. EVIDENCE ACQUSITION: A literature review from PubMed/MEDLINE, EMBASE, Cochrane, Google Scholar and Web of Science databases was conducted from 1999 to 2022 to identify articles concerning TPVB and ESPB for cardio-thoracic surgery or thoracic procedures in patients under anticoagulant or antiplatelet therapy. EVIDENCE SYNTHESIS: A total of 1704 articles were identified from the initial search. After removing duplicates and not-pertinent articles, 15 articles were analyzed. The results demonstrated a low risk of bleeding for TPVB and minimal or absent risk for ESPB. Ultrasound guidance was extensively used to perform ESPB, but not for TPVB. CONCLUSIONS: Although the low level of evidence available, TPVB and ESPB are reasonably safe options in patients ineligible for epidural anesthesia due to antithrombotic therapy. The few published studies suggest that ESPB offers a risk profile safer than TPVB and the use of ultrasound guidance minimizes any complication. Since the literature available does not allow us to draw definitive conclusions, future adequately-powered trials are warranted to determine the indications and the safety of TPVB and ESPB in patients receiving anticoagulant or antiplatelet therapy.

Preoperative SARS-CoV-2 Infection Screening before Thoracic Surgery during COVID-19 Pandemic: A Multicenter Retrospective Study.

Objectives: During coronavirus disease (COVID-19) pandemic, preoperative screening before thoracic surgery is paramount in order to protect patients and staff from undetected infections. This study aimed to determine which preoperative COVID-19 screening tool was the most effective strategy before thoracic surgery. Methods: This retrospective cohort multicenter study was performed at 3 Italian thoracic surgery centers. All adult patients scheduled for thoracic surgery procedures from 4th March until 24th April, 2020, and submitted to COVID-19 preoperative screenings were included. The primary outcome was the yield of screening of the different strategies. Results: A total of 430 screenings were performed on 275 patients; 275 anamnestic questionnaires were administered. 77 patients were screened by an anamnestic questionnaire and reverse transcriptase polymerase chain reaction (RT-PCR). 78 patients were selected to combine screening with anamnestic questionnaire and chest computed tomography (CT). The positive yield of screening using a combination of anamnestic questionnaire and RT-PCR was 7.8% (95% CI: 2.6-14.3), while using a combination of anamnestic questionnaire and chest CT was 3.8% (95% CI: 0-9). Individual yields were 1.1% (95% CI: 0-2.5) for anamnestic questionnaire, 5.2% (95% CI: 1.3-11.7) for RT-PCR, and 3.8% (95% CI: 0-9). Conclusions: The association of anamnestic questionnaire and RT-PCR is able to detect around 8 positives in 100 asymptomatic patients. This combined strategy could be a valuable preoperative SARS-CoV-2 screening tool before thoracic surgery.

Bilateral Ultrasound-Guided Erector Spinae Plane Block for Pectus Excavatum Surgery: A Retrospective Propensity-Score Study.

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.

Airway management for one lung ventilation during COVID-19 pandemic: a survey within Italian anesthesiologists.

BACKGROUND: Airway management for thoracic surgery represents a high risk setting for SARS-CoV-2 infection diffusion due to complex and invasive airway instrumentation and techniques. RESULTS: An 18-item questionnaire was submitted to the 56 members of the Thoracic subcommittee of the SIAARTI Cardio-Thoraco-Vascular Research Group to provide a snapshot of current situation and national variability of devices and procedures for airway management during the COVID-19 pandemic. The response rate was 64%. Eighty-three percent of anesthetists declared that they modified their airway management strategies. The Hospital Management considered necessary to provide a complete level 3 personal protective equipment for thoracic anesthetists only in 47% of cases. Double-lumen tube and bronchial blocker were preferred by 53% and 22% of responders to achieve one-lung ventilation respectively. Over 90% of responders considered the videolaryngoscope with separate screen and rapid sequence induction/intubation useful to minimize the infection risk. Thirty-nine percent of participants considered mandatory the bronchoscopic check of airway devices. Vivasight-DL was considered comfortable by more than 50% of responders while protective box and plastic drape were judged as uncomfortable by most of anesthetists. CONCLUSIONS: The survey reveals many changes in the clinical practice due to SARS-CoV-2 outbreak. A certain diffusion of new devices such as the VivaSight-DL and barrier enclosure systems emerged too. Finally, we found that most of Italian hospitals did not recognize thoracic anesthesia as a high-risk specialty for risk of virus diffusion.

Successful Total Tracheal Replacement by Cryopreserved Aortic Allograft in a Patient Post-COVID-19 Infection.

This is the first report to our knowledge of a successful total tracheal replacement in a post-COVID-19 patient by cryopreserved aortic allograft. The graft was anastomosed to the cricoid and carina; a silicon stent was inserted to ensure patency. The patient was extubated on the operative table and was immediately able to breathe, speak, and swallow. No immunosuppression was administered. Three weeks after surgery, the patient was discharged from hospital in excellent health, and was able to resume his normal lifestyle, work, and activity as an amateur cyclist. Two months after surgery, the patient assumes aerosol with saline solution three times per day and no other therapy; routine bronchoscopy to clear secretions is no longer needed.

Anesthetic Management of an Adult Patient With Down Syndrome for Thoracic Surgery.

The anesthetic management of adult patient with Down syndrome (DS) can be challenging due to poor patient cooperation, age-related comorbidities, and a possible difficult airway. Thoracic anesthesia requires an advanced airway management; thus, treatment of DS patients can be particularly demanding. An accurate preoperative assessment is paramount in order to plan a well-designed perioperative strategy in advance. This report describes the anesthetic management of an adult patient affected by DS who underwent pleural decortication for pleural empyema.

Laryngeal mask versus endotracheal tube for airway management in tracheal surgery: a case-control matching analysis and review of the current literature.

OBJECTIVES: The endotracheal tube (ETT) and the laryngeal mask airway (LMA) are possible strategies for airway management during tracheal resection and reconstruction for tracheal and laryngotracheal stenosis. The goal of the study was to analyse and compare outcomes in the LMA and ETT groups. METHODS: Between 2003 and 2020, a total of 184 patients affected by postintubation, post-tracheostomy and idiopathic stenosis who had tracheal or laryngotracheal resections and reconstructions via a cervicotomy were retrospectively enrolled in this single-centre study. In 29 patients, airway management was achieved through LMA during tracheal surgery, whereas in 155 patients, it was achieved through ETT. A case-control matching analysis was performed with a 1:1 ratio, according to age, gender, body mass index, aetiology and length of stenosis (1-4 cm), resulting in 22 patients managed through LMA (LMA group) matched with 22 patients managed through ETT (ETT group). RESULTS: No significant differences were found in the reintubation rate, 30-day mortality and postoperative length of stay. Operative time was shorter in patients with LMA (96.23 ± 34.72 min in the ETT group vs 76.14 ± 26.94 min in the LMA group; P = 0.043). Intensive care unit (ICU) admission rate and stay were lower in the LMA group [18 in the ETT group vs 8 in the LMA group, odds ratio = 10.17, confidence interval (CI) 95% 1.79-57.79; P = 0. 009; 22.77 ± 16.68 h in ETT group vs 9.23 ± 13.51 h in LMA group; P = 0.005]. Dysphonia was more frequent in the ETT group than in the LMA group (20 in the ETT group vs 11 in the LMA group, odds ratio = 13.79, CI 95% 1.86-102; P = 0.010). CONCLUSIONS: LMA is a feasible option for airway management in tracheal surgery, with lower operative time, ICU admission rate, ICU length of stay and postoperative dysphonia occurrence.

Airway management by i-gel for open tracheal resection and reconstruction via combined cervicotomy and sternotomy surgical approach: A case report.

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.

Intraoperative cardiac function assessment by transesophageal echocardiography versus FloTrac/Vigileo™ system during pectus excavatum surgical repair.

BACKGROUND: Pectus excavatum (PE), a congenital deformity of the chest wall, can lead to cardiac compression and related symptoms. PE surgical repair can improve cardiac function. Intraoperative transesophageal echocardiography (TEE) has been successfully employed to assess intraoperative hemodynamic variations in patients undergoing PE repair. FloTrac/Vigileo™ system (Edwards Life-sciences Irvine, CA) (FT/V) is a minimally invasive cardiac output monitoring system. This retrospective study aimed to assess hemodynamic changes in surgical repair of PE using FT/V and concordance with parameters measured by TEE. RESULTS: N=19 patients submitted to PE repair via Ravitch or Nuss technique were enrolled. Intraoperative cardiac assessments simultaneously obtained via TEE and FT/V system were investigated. The agreement between TEE-derived cardiac output (CO-TEE) and FT/V system parameter (COAP) was evaluated. The relationship between COTEE and COAP was analyzed for all data using linear regression analysis. A significant correlation between COAP and COTEE values (R = 0.65, p < 0.001) was found. Bland-Altman analysis of COAP and COTEE showed a bias of 0.13 L/min and a limit of agreement of - 2.33 to 2.58 L/min, with a percentage error of 48%. Intraoperative measurements by TEE and FT/V both showed a significant increase in CO after surgical correction of PE (p < 0.005). CONCLUSIONS: FT/V system compared to TEE in hemodynamic monitoring during PE surgery yielded clinically unacceptable results due to a high percentage error. After surgical correction of PE, CO, measured by TEE and FT/V, significantly improved.

Recommendations from the Italian intersociety consensus on Perioperative Anesthesia Care in Thoracic surgery (PACTS) part 1: preadmission and preoperative care.

INTRODUCTION: Anesthetic care in patients undergoing thoracic surgery presents specific challenges that necessitate standardized, multidisciplionary, and continuously updated guidelines for perioperative care. METHODS: A multidisciplinary expert group, the Perioperative Anesthesia in Thoracic Surgery (PACTS) group, comprising 24 members from 19 Italian centers, was established to develop recommendations for anesthesia practice in patients undergoing thoracic surgery (specifically lung resection for cancer). The project focused on preoperative patient assessment and preparation, intraoperative management (surgical and anesthesiologic care), and postoperative care and discharge. A series of clinical questions was developed, and PubMed and Embase literature searches were performed to inform discussions around these areas, leading to the development of 69 recommendations. The quality of evidence and strength of recommendations were graded using the United States Preventative Services Task Force criteria. RESULTS: Recommendations for preoperative care focus on risk assessment, patient preparation (prehabilitation), and the choice of procedure (open thoracotomy vs. video-assisted thoracic surgery). CONCLUSIONS: These recommendations should help pulmonologists to improve preoperative management in thoracic surgery patients. Further refinement of the recommendations can be anticipated as the literature continues to evolve.

Recommendations from the Italian intersociety consensus on Perioperative Anesthesa Care in Thoracic surgery (PACTS) part 2: intraoperative and postoperative care.

INTRODUCTION: Anesthetic care in patients undergoing thoracic surgery presents specific challenges that require a multidisciplinary approach to management. There remains a need for standardized, evidence-based, continuously updated guidelines for perioperative care in these patients. METHODS: A multidisciplinary expert group, the Perioperative Anesthesia in Thoracic Surgery (PACTS) group, was established to develop recommendations for anesthesia practice in patients undergoing elective lung resection for lung cancer. The project addressed three key areas: preoperative patient assessment and preparation, intraoperative management (surgical and anesthesiologic care), and postoperative care and discharge. A series of clinical questions was developed, and literature searches were performed to inform discussions around these areas, leading to the development of 69 recommendations. The quality of evidence and strength of recommendations were graded using the United States Preventive Services Task Force criteria. RESULTS: Recommendations for intraoperative care focus on airway management, and monitoring of vital signs, hemodynamics, blood gases, neuromuscular blockade, and depth of anesthesia. Recommendations for postoperative care focus on the provision of multimodal analgesia, intensive care unit (ICU) care, and specific measures such as chest drainage, mobilization, noninvasive ventilation, and atrial fibrillation prophylaxis. CONCLUSIONS: These recommendations should help clinicians to improve intraoperative and postoperative management, and thereby achieve better postoperative outcomes in thoracic surgery patients. Further refinement of the recommendations can be anticipated as the literature continues to evolve.

Perspectives in surgical and anaesthetic management of lung cancer in the era of coronavirus disease 2019 (COVID-19).

Early in 2020, coronavirus disease 2019 (COVID-19) quickly spread globally, giving rise to a pandemic. In this critical scenario, patients with lung cancer need to continue to receive optimal care and at the same be shielded from infection with the potentially severe acute respiratory syndrome coronavirus 2. Upgrades to the prevention and control of infection have become paramount in order to lower the risk of hospital contagion. Aerosol-generating procedures such as endotracheal intubation or endoscopic procedures may expose health care workers to a high risk of infection. Moreover, thoracic anaesthesia usually requires highly complex airway management procedures because of the need for one-lung isolation and one-lung ventilation. Therefore, in the current pandemic, providing a fast-track algorithm for scientifically standardized diagnostic criteria and treatment recommendations for patients with lung cancer is urgent. Suggestions for improving existing contagion control guidelines are needed, even in the case of non-symptomatic patients who possibly are responsible for virus spread. A COVID-19-specific intraoperative management strategy designed to reduce risk of infection in both health care workers and patients is also required.

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.
