Anaesthetic and perioperative considerations for extrapleural pneumonectomy and extended pleurectomy/decortication: a scoping review protocol.

Introduction: Extrapleural pneumonectomy (EPP) and extended pleurectomy/decortication (ePD) are surgical cytoreductive techniques aimed at achieving macroscopic resection in malignant pleural tumours such as pleural mesothelioma, non-mesothelioma pleural malignancies such as thymoma and sarcoma, and rarely for pleural tuberculosis, in a more limited fashion. Despite extensive studies on both surgical techniques and consequences, a significant knowledge gap remains regarding how best to approach the perioperative anaesthesia challenges for EPP and ePD.It is unknown if the risk stratification processes for such surgeries are standardised or what types of functional and dynamic cardiac and pulmonary tests are employed preoperatively to assist in the perioperative risk stratification.

Heart-Lung Transplantation: Technical Modifications to Simplify the Procedure.

Heart-lung transplantation is a mature therapy but has perioperative complications, such as phrenic nerve dysfunction and mediastinal bleeding. We report our technical modifications to simplify the procedure.

Right atrial appendage rupture and cardiac tamponade secondary to blunt trauma.

Background: Right atrial appendage rupture from blunt trauma is exceedingly rare, even more so when no other chest wall injuries are found. Very few cases have been documented with respect to survival from such an injury.

Purpose: To highlight the optimal management of such cases, namely through timely and safe transport to a trauma centre, maintaining a high degree of clinical suspicion for tamponade, early diagnostic ultrasound use, pericardial decompression, haemorrhage control and situational control.

Extracorporeal Membrane Oxygenation as a Bridge to Surgical Repair of Postinfarct Ventricular Septal Defect.

Postinfarct ventricular septal defect (PIVSD) is associated with high mortality and the management of these patients has been a challenge with little improvement in outcomes. We commenced a protocol of veno-arterial extracorporeal membrane oxygenation (VA ECMO) for those patients who present in cardiogenic shock with the aim to improve end-organ function before definitive surgical repair to reduce postoperative mortality. This study reviewed the results of this strategy.

ECMO (extra corporeal membrane oxygenation) in major trauma: A 10 year single centre experience.

Aim To review the indications, complications and outcomes of extracorporeal membrane oxygenation (ECMO) in major trauma patients. Methods Single centre, retrospective, cohort study. Results Over a ten year period, from 13,420 major trauma patients, 11 were identified from our institutional trauma registry as having received ECMO.

Diagnosis and treatment of lung disease associated with alpha one-antitrypsin deficiency: A position statement from the Thoracic Society of Australia and New Zealand.

AATD is a common inherited disorder associated with an increased risk of developing pulmonary emphysema and liver disease. Many people with AATD-associated pulmonary emphysema remain undiagnosed and therefore without access to care and counselling specific to the disease. AAT augmentation therapy is available and consists of i.

Survival following traumatic thoracic compartment syndrome managed with VV-ECMO.

Whilst post-traumatic respiratory failure is the most common indication for use of VV-ECMO in trauma patients, its use in traumatic thoracic compartment syndrome is not yet well described. Thoracic compartment syndrome, a rare complication of thoracic trauma, occurs in the setting of chest wall injuries, impaired chest wall compliance, pulmonary contusions and subsequent high ventilatory pressures. This in turn impairs venous return and increases risk of circulatory arrest due to obstructive shock.

A donor PaO/FiO < 300 mm Hg does not determine graft function or survival after lung transplantation.

Background: A donor arterial PO/FiO (P/F ratio) of less than the 300 threshold would frequently result in either exclusion of the donor or placement of the lungs on ex vivo lung perfusion (EVLP). The aim was to investigate the veracity of the P/F ratio threshold of 300 for donor lung acceptability.

Methods: In 93 brain dead lung donors, arterial blood gases were drawn in the intensive care unit (ICU) just before procurement and each of the 4 donor pulmonary veins in the operating room (OR).

A successful aggressive surgical and medical approach to pulmonary artery obstruction due to Mycobacterium abscessus infection post lung transplantation.

Mycobacterium abscessus infection following lung transplantation has historically been associated with poor outcomes. We report a case of bilateral lung retransplantation complicated by obstruction of the right pulmonary artery secondary to M. abscessus mycotic aneurysm.

Sequential unilateral lung volume reduction for emphysema - Stretching the benefit.

Bronchoscopic Lung Volume Reduction (BLVR) and Surgical Lung Volume Reduction (SLVR) and are two different approaches used to remodel severely emphysematous lungs to improve lung function and quality-of-life. We present a case initially referred for lung transplantation, where sequential left upper lobe BLVR and 7 years later right upper lobe SLVR, providing enduring physiological and functional improvement. The potential for sustained benefit via sequential unilateral lung volume reduction is under-appreciated.

Feasibility and Safety of a Transthoracic Pneumostoma Airway Bypass in Severe Emphysema Patients.

Background: Emphysema is characterised by airflow obstruction, hyperinflation, and resultant dyspnoea. It is worth investigating whether decompression improves lung mechanics and enhances quality of life (QoL).

Objectives: The purpose of this study was to describe the feasibility and safety of creating a transthoracic pneumostoma to enable lung reduction.

Isavuconazole as salvage therapy for mucormycosis.

Mucormycosis carries a high mortality rate with few therapeutic options available. We describe a man with pulmonary/splenic mucormycosis complicating hypoplastic myelodysplastic syndrome on a background of chronic kidney disease, who achieved a complete response with salvage isavuconazole therapy following intolerance of consecutive courses of liposomal amphotericin and posaconazole therapy.

Coronary Vasospasm as an Unexpected Cause of Intraoperative Hemodynamic Instability and Cardiac Arrest.

We present a case of intraoperative coronary artery vasospasm during thoracic surgery causing profound hemodynamic instability. A 68-year-old man undergoing completion right pneumonectomy exhibited intraoperative widespread ST elevation with associated hypotension. Transesophageal echocardiography performed by the anesthetist revealed hypokinetic apical and lateral walls, prompting transportation to the catheterization laboratory, with angiography demonstrating widespread coronary artery spasm.

Management of refractory chylothorax in pulmonary lymphangioleiomyomatosis.

This case reports the successful management of chylothorax in a non-transplanted patient with pulmonary lymphangioleiomyomatosis (pLAM). Prolonged initial therapy failed, including total parenteral nutrition, pleural drainage, surgical pleurodesis, and pleurectomy. Commencement of sirolimus 2 mg daily (2 mg alternating days had failed) led to resolution of chylothorax after 20 days.

Safety, feasibility, and effect of remote ischemic conditioning in patients undergoing lung transplantation.

Background: Primary graft dysfunction (PGD) remains a significant problem after lung transplantation. Data from animal and clinical studies suggest that remote ischemic conditioning (RIC) may reduce ischemia-reperfusion injury in solid organ transplantation.

Methods: A pilot randomized controlled trial of 60 patients undergoing bilateral sequential lung transplantation assessed the utility of RIC in attenuating PGD.

Buying time: The use of extracorporeal membrane oxygenation as a bridge to lung transplantation in pediatric patients.

To describe our experience to date of four children with end-stage lung disease who have been bridged with ECMO to successful lung transplantation in our institution. Between March 2006 and June 2012, a total of 21 pediatric patients successfully underwent lung transplantation within The Alfred's lung transplantation program. This included four children who were bridged on ECMO prior to transplantation according to the "ECMO bridge to transplant" protocol and whose clinical notes and outcomes were reviewed.

Sustained function of genetically modified porcine lungs in an ex vivo model of pulmonary xenotransplantation.

Background: Xenotransplantation could provide a solution to the donor shortage that is currently the major barrier to solid-organ transplantation. The ability to breed pigs with multiple genetic modifications provides a unique opportunity to explore the immunologic challenges of pulmonary xenotransplantation.

Methods: Explanted lungs from wild-type and 3 groups of genetically modified pigs were studied: (i) α1,3-galactosyltransferase gene knockout (GTKO); (ii) GTKO pigs expressing the human complementary regulatory proteins CD55 and CD59 (GTKO/CD55-59); and (iii) GTKO pigs expressing both CD55-59 and CD39 (GTKO/CD55-59/CD39).

Correlation of mutation status and survival with predominant histologic subtype according to the new IASLC/ATS/ERS lung adenocarcinoma classification in stage III (N2) patients.

Introduction: We investigated the relationship between predominant subtype, according to the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society International Multidisciplinary Lung Adenocarcinoma Classification; mutation status; and patient outcome in stage III (N2) lung adenocarcinoma.

Methods: We identified 69 patients with stage III (N2) lung adenocarcinoma operated on with curative intent between 1993 and 2011 who had adequate tumor tissue for molecular analysis and adequate follow-up time for survival analysis. DNA was isolated and tested for mutations using Sequenom's OncoCarta Panel (v1.

Carbon dioxide insufflation in open-chamber cardiac surgery: a double-blind, randomized clinical trial of neurocognitive effects.

Objective: The aims of this study were first to analyze neurocognitive outcomes of patients after open-chamber cardiac surgery to determine whether carbon dioxide pericardial insufflation reduces incidence of neurocognitive decline (primary end point) as measured 6 weeks postoperatively and second to assess the utility of carbon dioxide insufflation in cardiac chamber deairing as assessed by transesophageal echocardiography.

Methods: A multicenter, prospective, double-blind, randomized, controlled trial compared neurocognitive outcomes in patients undergoing open-chamber (left-sided) cardiac surgery who were assigned carbon dioxide insufflation or placebo (control group) in addition to standardized mechanical deairing maneuvers.

Results: One hundred twenty-five patients underwent surgery and were randomly allocated.
