Peripheral regional anesthesia is a commonly used and safe procedure and eneral complications or side effects are generally rare. Nerve damage has an incidence <0.1% depending on the definition and the prognosis is good. To avoid bleeding complications the national standards of block performance under antithrombotic therapy should be respected. ⋯ Potential infectious complications can occur mainly as a result of catheter techniques and require a strict aseptic approach. Further rare complications are allergies, dislocation of catheters and knotting or loops in catheters. Besides the general complications, there are some specific complications depending on the puncture site, such as pneumothorax or renal puncture.

Patients with multiple trauma presenting with apnea or a gasping breathing pattern (respiratory rate <6/min) require prehospital endotracheal intubation (ETI) and ventilation. Additional indications are hypoxia (S(p)O(2)<90% despite oxygen insufflation and after exclusion of tension pneumothorax), severe traumatic brain injury [Glasgow Coma Scale (GCS)<9], trauma-associated hemodynamic instability [systolic blood pressure (SBP)<90 mmHg] and severe chest trauma with respiratory insufficiency (respiratory rate >29/min). The induction of anesthesia after preoxygenation is conducted as rapid sequence induction (analgesic, hypnotic drug, neuromuscular blocking agent). ⋯ Normoventilation should be the goal of mechanical ventilation. After arrival in the resuscitation room the ventilation will be controlled and guided with the help of arterial blood gas analyses. After temporary removal of a cervical collar, the cervical spine needs to be immobilized by means of manual in-line stabilization when securing the airway.

Intensive care medicine plays an important role in the medical care of patients as well as the economic success of hospitals. Knowledge and implementation of recent relevant scientific evidence are prerequisites for high quality care in intensive care medicine. ⋯ In 2010 and up to June 2011 many studies with high patient numbers have been published. The main topics were the treatment of respiratory failure, sepsis and investigations to improve analgosedation.

The demographic change is associated with an increasing number of elderly patients with serious comorbidities. The prevalence of coronary heart disease in particular increases with age and raises the risk of perioperative myocardial ischemia. In the last few years various interventions have been evaluated to lower the perioperative risk for serious cardiovascular events. ⋯ Besides ischemic and anesthetic-induced preconditioning the noninvasive technique of remote preconditioning offers interesting possibilities, especially for patients with serious comorbidities; however, large scale randomized clinical multicentre trials are still needed. Regarding cardioprotective effectiveness, the clinical data for regional anesthesia are very heterogeneous; nevertheless regional anesthesia is very effective in postoperative pain therapy. Therefore regional anesthesia should be used as a part of multimodal therapy concepts to lower the risk of perioperative cardiovascular events.

Ambulatory surgery continues to grow and is slowly becoming routine in the majority of cases. Although the development of ambulatory surgery in Germany appears to be somewhat delayed, this is actually a chance to learn from worldwide experiences and avoid the mistakes others made earlier. This article investigates current trends and developments in day case surgery and discusses the extended role and influence of the anesthetist in the perioperative setting.
