ReviewSystemic lidocaine in surgical procedures: effects beyond sodium channel blockade.
This review presents current data on the systemic administration of lidocaine. The focus is on studies in the perioperative setting. In addition, there is a brief look at experimental data on the effect of lidocaine at the molecular level. ⋯ Positive effects on postoperative pain, as well as on bowel motility and hospital discharge time, have regularly been observed. However, contradictory findings have also been published. As almost all of the studies only include very small patient numbers, large multicenter investigations are needed.

ReviewManagement of anaesthetic emergencies and complications outside the operating room.
Anesthesia outside the operating room is commonly uncomfortable and risky. In this setting, anesthetic emergencies or complications may occur. This review aims to report the most recent updates regarding the management of prehospital anesthesia, anesthesia in the trauma and emergency rooms, and anesthesia for endoscopy and interventional radiology. ⋯ Anesthesia outside the operating room requires careful monitoring to avoid side-effects and education of nonanaesthetists when they are involved. A useful tool is to continuously improve the protocols and checklists to make anesthesia in this setting safer.

ReviewImportant issues for perioperative systemic antimicrobial prophylaxis in surgery.
Prevention of surgical site infections is a key issue to patient safety and the success of surgical interventions. Systemic antimicrobial prophylaxis is one important component of a perioperative infection prevention bundle. This review focuses on selected recent developments and important concepts in the field. ⋯ Most frequently, anaesthesiologists administer perioperative antimicrobial prophylaxis. Identification of core principles and harmonization of protocols should facilitate this task and thus help to improve patient safety and to monitor compliance. However, local and regional epidemiology have to be taken into account in order to establish local protocols.

To discuss the recent advances in sedation and anesthesia for the practice of both flexible and rigid bronchoscopy, which are increasingly performed outside of the operating room by interventional pulmonologists and thoracic surgeons. ⋯ As our practice expands, relocation of appropriately triaged pulmonary interventional procedures including rigid bronchoscopy that were previously assigned to a traditional operating room setting improves provider flexibility, presents more cost-effective options while maintaining patient safety and satisfaction and reducing the time to recovery. Anesthesia practice has, therefore, shifted to caring for these sick patients outside the operating room and increasingly cooperation between anesthesiologist and proceduralist is required.

ReviewManagement of right ventricular dysfunction in the perioperative setting.
This review summarizes the approach to and recent developments in the treatment of acute right ventricular dysfunction and failure in the perioperative setting. Right ventricular failure, defined as the inability to deliver sufficient blood flow through the pulmonary circulation at normal central venous pressure, is a common problem in the perioperative setting and is associated with an increased mortality. The failure of the right ventricle is caused by reduced right ventricular contractility or an increased right ventricular afterload or both. ⋯ Right ventricular dysfunction may cause venous congestion and systemic hypoperfusion. After identifying right ventricular dysfunction, the primary goal is to correct reversible causes of excessive load or reduced right-ventricular contractility. If the underlying abnormalities cannot be reversed, diuretic, vasodilator, or inotropic therapy may be required.
