Anesthesia and fast-track in video-assisted thoracic surgery (VATS): from evidence to practice.
In thoracic surgery, the introduction of video-assisted thoracoscopic techniques has allowed the development of fast-track protocols, with shorter hospital lengths of stay and improved outcomes. The perioperative management needs to be optimized accordingly, with the goal of reducing postoperative complications and speeding recovery times. Premedication performed in the operative room should be wisely administered because often linked to late discharge from the post-anesthesia care unit (PACU). ⋯ Fluid therapy needs to be administered critically, to avoid both overload and cardiovascular compromisation. All these practices are analyzed singularly with the aid of the most recent evidences aimed at the best patient care. Finally, a few notes on some of the latest trends in research are presented, such as non-intubated video-assisted thoracoscopic surgery (VATS) and intravenous lidocaine.

Extracorporeal membrane oxygenation (ECMO) is described as a modified, smaller cardiopulmonary bypass circuit. The veno-venous (VV) ECMO circuit drains venous blood, oxygenate the blood, and pump the blood back into the same venous compartment. Draining and reinfusing in the same compartment means there are a risk of recirculation. ⋯ Efficiency can be reasonable in either strategy if the cannulas are carefully positioned and monitored during the dynamic procedure of pulmonary disease. The disadvantage draining from IVC only occurs when there is a need for converting from VV to veno-arterial (VA) ECMO, reinfusing in the femoral artery. Then draining from SVC is the most efficient strategy, draining low saturated venous blood, and also means low risk of dual circulation.

Data evaluating pharmacokinetic/pharmacodynamic (PK/PD) aspect in the pediatric population are scarce especially regarding the pediatric intensive care unit. Dosing of frequently used drugs (sedatives, analgesics, antibiotics and cardiovascular drugs) are mainly based on non "pediatric intensive care unit (PICU)" patients, and sometimes are translated from adult patients. ⋯ The use of extracorporeal membrane oxygenation is associated with major PK and PD changes, especially in neonates and children. The objective of this review is to assess the current literature for pediatric PK data in patients receiving extracorporeal membrane oxygenation (ECMO).

Invasive mediastinal lymph node staging is essential to resectable non-small cell lung cancer (NSCLC) patients. This retrospective study aimed to compare the diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) against cervical mediastinoscopy (CMS) in radiologically enlarged mediastinal lymph nodes. ⋯ For clinically suspected lung cancers with enlarged mediastinal lymph nodes, both EBUS-TBNA and CMS are favorable invasive mediastinal staging options. EBUS-TBNA may be preferred for its higher malignant diagnostic sensitivity and fewer complications.

Case Reports
Successful extracorporeal cardiopulmonary resuscitation in a postpartum patient with amniotic fluid embolism.
Amniotic fluid embolism (AFE) is a rare but fatal obstetric emergency, which is characterized by a sudden cardiovascular collapse, respiratory failure, and disseminated intravascular coagulation (DIC). We report a case of sudden cardiac arrest due to an amniotic-fluid embolism which was successfully treated with veno-arterial extracorporeal membrane oxygenation (ECMO). A 32-year-old female at 39.1 weeks of gestation was scheduled for induction labor. ⋯ Despite the appropriate cardiopulmonary resuscitation, she became hypoxemic and experienced recurrent cardiovascular collapse. ECMO was applied promptly, and the patient became stable rapidly and was discharged without any complications. ECMO seems to be a proper treatment option for catastrophic amniotic-fluid embolism.
