ReviewEffect of left ventricular diastolic dysfunction on development of primary graft dysfunction after lung transplant.
Primary graft dysfunction (PGD) is one of the most common complications after lung transplant and is associated with significant early and late morbidity and mortality. The cause of primary graft dysfunction is often multifactorial involving patient, donor, and operational factors. Diastolic dysfunction is increasingly recognized as an important risk factor for development of PGD after lung transplant and here we examine recent evidence on the topic. ⋯ Patients with diastolic dysfunction is more likely to suffer from PGD after lung transplant. From the lung transplant candidate selection to perioperative and posttransplant care, thorough evaluation and documentation diastolic dysfunction to guide patient care are imperative.

ReviewAntibiotic dosing during extracorporeal membrane oxygenation: does the system matter?
The aims of this review are to discuss the impact of extracorporeal membrane oxygenation (ECMO) on antibiotic pharmacokinetics and how this phenomenon may influence antibiotic dosing requirements in critically ill adult ECMO patients. ⋯ An advanced understanding of the pharmacokinetic alterations in critically ill patients receiving ECMO is essential to provide optimal antibiotic dosing in these complex patients pending robust dosing guidelines. Antibiotic dosing in this patient population should generally align with the recommended dosing strategies for critically ill patients not on ECMO support. Performing therapeutic drug monitoring (TDM) to guide antibiotic dosing in this patient population appears useful.

ReviewImpact of geriatric co-management programmes on outcomes in older surgical patients: update of recent evidence.
To determine the impact of geriatric co-management programmes on outcomes in older patients undergoing a surgical procedure. ⋯ There was a shorter length of stay, less mortality and a lower readmission rate. However, there was uncertainty whether the results are clinically relevant and the GRADE of evidence was low. It was uncertain whether the outcomes time to surgery and complications were improved. The evidence is limited to hip fracture patients.

Lung transplantation can be performed off-pump, with sequential one-lung ventilation, or using mechanical circulatory support (MCS). MCS can either be in the form of cardiopulmonary bypass (CPB) or veno-arterial or veno-venous extracorporeal membrane oxygenation (VA ECMO or VV ECMO).This article reviews the indications, benefits and limitations of these different techniques and evaluates their effect on outcomes. ⋯ The trend toward ECMO and away from cardiopulmonary bypass is backed up with good survival rates. However, to date, there has not been a randomized controlled trial to further guide the choice of MCS strategy for lung transplantation.

Right ventricular (RV) dysfunction following thoracotomy and pulmonary resection is a known phenomenon but questions remain about its mechanism, risk factors, and clinical significance. Acute RV dysfunction can present intraoperatively and postoperatively, persisting for 2 months after surgery. ⋯ In this review, we examine the most recent literature on RV dysfunction following lung resection, including possible mechanisms, time span of RV dysfunction, and available diagnostic modalities. The clinical relevance of these factors on preoperative assessment and risk stratification are presented.
