ReviewShould fluid management in thoracic surgery be goal directed?
To find a reliable answer to the question in the title: Should fluid management in thoracic surgery be goal directed? ⋯ Although the evidence level is low, GDT is generally associated with fewer postoperative complications. It can be helpful in decision-making for volume-optimization, timing of fluid administration, and indication of vasoactive agents.

The development of pulmonary atelectasis is common in the surgical patient. Pulmonary atelectasis can cause various degrees of gas exchange and respiratory mechanics impairment during and after surgery. In its most serious presentations, lung collapse could contribute to postoperative respiratory insufficiency, pneumonia, and worse overall clinical outcomes. ⋯ Interventions such as noninvasive positive pressure ventilatory support may be beneficial in specific patients at high risk for pulmonary atelectasis (e.g., obese) or those with clinical presentations consistent with lung collapse (e.g., postoperative hypoxemia after abdominal and cardiothoracic surgeries). Preoperative interventions may open new opportunities to minimize perioperative lung collapse and prevent pulmonary complications. Knowledge of pathophysiologic mechanisms of atelectasis and their consequences in the healthy and diseased lung should provide the basis for current practice and help to stratify and match the intensity of selected interventions to clinical conditions.

Chronic postsurgical pain (CPSP) affects an estimated 10% to 50% of adults depending on the type of surgical procedure. Clinical prediction models can help clinicians target preventive strategies towards patients at high risk for CPSP. Therefore, the objective of this systematic review was to identify and describe existing prediction models for CPSP in adults. ⋯ The most common predictors identified in final prediction models included preoperative pain in the surgical area, preoperative pain in other areas, age, sex or gender, and acute postsurgical pain. Clinical prediction models may support prevention and management of CPSP, but existing models are at high risk of bias that affects their reliability to inform practice and generalizability to wider populations. Adherence to standardized guidelines for clinical prediction model development is necessary to derive a prediction model of value to clinicians.

ReviewFluid escapes to the "third space" during anesthesia, a commentary.
The "third fluid space" is a concept that has caused much confusion for more than half a century, dividing anesthesiologists into believers and non-believers. ⋯ During anesthesia and surgery one third of the infused crystalloid fluid is at least temporarily unavailable for excretion, which probably contributes to postoperative weight increase and edema.

ReviewDoes thoracic epidural anaesthesia constitute over-instrumentation in video- and robotic-assisted thoracoscopic lung parenchyma resections?
Effective and sustained perioperative analgesia in thoracic surgery and pulmonary resection is beneficial to patients by reducing both postoperative pulmonary complications and the incidence of chronic pain. In this review, the indication of thoracic epidural anaesthesia in video- (VATS) and robotic-assisted (RATS) thoracoscopy shall be critically objectified and presented in a differentiated way. ⋯ Since clear evidence-based recommendations for optimal postoperative analgesia are still lacking in VATS and RATS, there can be no universal recommendation that fits all centres and patients. In this context, thoracic epidural analgesia is the most effective analgesia procedure for perioperative pain control in VATS and RATS-assisted surgery for patients with pulmonary risk factors.
