Purpose of review Enhanced Recovery After Thoracic Surgery (ERATS) has gained momentum over the past few years, although the evidence base and expert recommendations lag behind other specialties. This review will present and examine key points from the first guidelines for enhanced recovery after lung surgery, released in 2018, jointly sponsored by the European Society of Thoracic Surgeons and the Enhanced Recovery After Surgery Society. Recent findings The recently released guidelines present core components of enhanced recovery as they pertain to lung resection surgery. Although evidence is still sparse in some areas, the guidelines summarize the available literature and incorporate levels of recommendation based upon the strength of available data as well as expert consensus. As of yet, the relative contribution of individual ERATS components to improvement in outcomes is unclear, but overall compliance does seem to be linked to positive results. Since the creation of the guidelines, additional literature related to ERATS has been released, and it will be incorporated and discussed into our review. Summary The creation of guidelines for enhanced recovery after lung resection will provide the thoracic anesthesiologist a framework upon which to build a comprehensive perioperative anesthetic plan.

Neuromonitoring in the elderly
Purpose of review To summarize recent recommendations on intraoperative electroencephalogram (EEG) neuromonitoring in the elderly aimed at the prevention of postoperative delirium and long-term neurocognitive decline. We discuss recent perioperative EEG investigations relating to aging and cognitive dysfunction, and their implications on intraoperative EEG neuromonitoring in elderly patients. Recent findings The incidence of postoperative delirium in elderly can be reduced by monitoring depth of anesthesia, using an index number (0–100) derived from processed frontal EEG readings. The recently published European Society of Anaesthesiology guideline on postoperative delirium in elderly now recommends guiding general anesthesia with such indices (Level A). However, intraoperative EEG signatures are heavily influenced by age, cognitive function, and choice of anesthetic agents. Detailed spectral EEG analysis and research on EEG-based functional connectivity provide new insights into the pathophysiology of neuronal excitability, which is seen in elderly patients with postoperative delirium. Summary Anesthesiologists should become acquainted with intraoperative EEG signatures and their relation to age, anesthetic agents, and the risk of postoperative cognitive complications. A working knowledge would allow an optimized and individualized provision of general anesthesia for the elderly.

Incremental value of noncerebral somatic tissue oxygenation monitoring for patients undergoing surgery
Purpose of the review There is increasing interest in the use of noncerebral somatic tissue oxygen saturation (SstO2) monitoring on the basis of near-infrared spectroscopy in patients undergoing surgery or residing in intensive care unit. The relevant question is whether SstO2 monitoring can improve the quality of care. In this article, we reviewed the clinical application of SstO2 monitoring in acute care, focusing on its use in patients undergoing surgery. Recent findings Multiple small cohort studies conducted on pediatric patients reported close associations of SstO2 measurements over different regions such as the splanchnic and renal tissue beds with systemic oxygenation, transfusion, hemodynamic indices, morbidity, and mortality. Conversely, there is paucity of literature on SstO2 monitoring in adult patients. The limited number of reports suggests that SstO2 levels over bulk muscles such as the thenar eminence, forearm, and lower leg during surgery are correlated with postoperative outcomes including postoperative nausea and vomiting and the length of hospital stay in adult patients undergoing surgery. The only pilot, randomized interventional study based on 50 patients undergoing surgery did not find a difference in outcomes on the basis of the use of SstO2 monitoring. Summary Somatic tissue oxygenation may represent an essential aspect of human physiology in acute care, and it is likely outcome-relevant based on observational cohort studies. Future research should examine whether SstO2-guided care can further improve patient outcomes using randomized controlled trials.

Extravascular lung water monitoring for thoracic and lung transplant surgeries
Purpose of review Excessive accumulation of extravascular lung water (EVLW) resulting in pulmonary edema is the most feared complication following thoracic surgery and lung transplant. ICUs have long relied on chest radiography to monitor pulmonary status postoperatively but the increasing recognition of the limitations of bedside plain films has fueled development of newer technologies, which offer earlier detection, quantitative assessments, and can aide in preoperative screening of surgical candidates. In this review, we focus on the emergence of transpulmonary thermodilution (TPTD) and lung ultrasound with a focus on the clinical integration of these modalities into current intraoperative and critical care practices. Recent findings Recent studies demonstrate transpulmonary thermodilution and lung ultrasound provide greater sensitivity and earlier detection of lung water accumulation and are useful to guide clinical management. Assessments from these techniques have predictive value of postoperative outcome. Further, EVLW assessment shows promise as a preoperative screening tool in lung transplant patients. Summary Monitoring EVLW in the perioperative period offers clinicians a powerful tool to guide fluid therapy and manage pulmonary edema. Both TPTD and lung ultrasound have unique attributes in the care of thoracic surgery and lung transplant patients.

Spinal cord perfusion protection for thoraco-abdominal aortic aneurysm surgery
Purpose of Review Spinal cord ischemia (SCI) is a devastating complication after open or endovascular aortic repair for thoracoabdominal aortic disease. The underlying pathogenesis is not fully understood but appears multifactorial. Multiple spinal cord protection strategies and monitoring techniques are currently utilized with variable results seen. The purpose of this review is to summarize important and recent findings related to cause, monitoring and impact of multiple spinal cord protection strategies. Recent Findings Recent data suggests collateral blood flow as the major determinant of spinal cord perfusion instead of individual intercostal vessels, potential role of transcutaneous near-infrared spectroscopy for monitoring of spinal cord perfusion and positive impact of implementing multimodal spinal cord protection strategies on reducing the risk of SCI. Summary SCI leading to paraplegia is a multifactorial complication that remains a major concern in complex aortic surgeries. Although there are no sufficient data to document the efficacy of spinal cord protection techniques individually, their effect on lowering the risk of SCI is most evident when used concomitantly using a multimodal approach that encompasses the perioperative and early postoperative period.

Prehabilitation is better than cure
Purpose of review With a continuously growing number of older patients undergoing major surgical procedures, reliable parameters practicable in perioperative routine revealing those patients at risk are urgently needed. Recently, the concept of 'prehabilitation' with its key elements exercise, nutrition and psychological stress reduction especially in frail patients is attracting increasing attention. Recent findings Literature search revealed a huge amount of publications in particular within the last 12 months. Although a single definition of both frailty and prehabilitation is still to be made, various players in the perioperative setting obviously are becoming increasingly convinced about a possible benefit of the program – referring to different components and measures performed. Although physiologically advantages seem obvious, there is hardly any reliable data on clinical outcomes resulting from properly performed studies. This applies especially to octogenarians; thus those at risk for adverse events the concept originally addresses. Summary Identifying high-risk patients at the earliest possible stage and increasing their physiological reserve prior to surgery is a promising approach that seems to result in remarkable improvements for older patients. However, further studies on effectiveness in a highly heterogeneous population and agreement on a common concept are mandatory before a final judgement can be given.

Biomarkers and postoperative cognitive function: could it be that easy?
Purpose of review Neurocognitive dysfunction after surgery is highly relevant in the elderly. The multifactorial manner of this syndrome has made it hard to define an ideal biomarker to predict individual risk and assess diagnosis and severity of delirium [postoperative delirium (POD)] and subsequent postoperative cognitive decline (POCD). This review summarizes recent literature on blood biomarkers for POD/POCD. Recent findings Markers for delirium have been searched for in the cerebrospinal fluid to examine the pathologic cascade. However, cerebrospinal fluid cannot be easily obtained in the perioperative setting. Thus, attention shifts toward prediction markers from patients' blood to determine the individual risk. In this regard, three major groups of peripheral blood markers could be distinguished: first, global, but unspecific markers associated with POD/POCD; second, specific and established markers related to neurocognitive function; and third, upcoming or newly described markers with less evidence. Solely neuron-specific enolase is an adequate biomarker based on recent literature. Summary Single markers for postoperative cognitive impairment cannot predict POD/POCD in geriatric patients. However, a wisely arranged battery of promising biomarkers might achieve a satisfying sensitivity and specificity for the preoperative assessment of subsequent cognitive decline. Adequately powered studies to prove this hypothesis are required. Correspondence to Simon T.

Delayed recovery following thoracic surgery: persistent issues and potential interventions
Purpose of review Lung and esophageal surgery remain a curative option for resectable cancers. However, despite advances in surgical and anesthesia practices, the inclusion of patients with comorbidities that would have previously not been offered curative resection presents additional concerns and challenges. Recent findings Perioperative complication rates remain high and prolonged and/or painful recovery are common. Further, many patients face a permanent decline in their functional status, which negatively affects their quality of life. Examination of the variables associated with high complications following thoracic surgery reveals patient, physician, and institutional factors in the forefront. Anesthesiologist training, Enhanced Recovery After Surgery protocols, and preparations to minimize "failure to rescue" when a complication does arise are key strategies to address adverse outcomes. Summary Delayed and complicated recovery after thoracic noncardiac surgery persist in current practice. This review analyzes the diverse factors that can impact complications and quality of life after lung surgery and the interventions that can help decrease length of stay and improve return to baseline conditions.
