[Ambulant Anesthesia: Limits and Possibilities].

The number of operations carried out on an outpatient basis is increasing in Germany. This trend has been observed for years. The prerequisite is an infrastructure that is in line with guidelines. The competence of the anesthetist must not be restricted to that of a standard specialist anesthetist, but the physician should have experience in ambulatory anesthesia. Well-adjusted comorbidities of the patient are generally not a contraindication for an outpatient procedure. The heavily overweight patient can also be operated on an outpatient basis if he is compliant, comorbidities are well adjusted and intensive postoperative care is ensured. Obstructive sleep apnea syndrome is per se not a contraindication for carrying out a surgical intervention on an outpatient basis. The intensive postoperative care and the presence of a CPAP device are also important in the recovery room. An important decision criterion in cardiac patients is the determination of the metabolic equivalent (MET). A MET value > 4 is considered sufficient for outpatient procedures. Postoperatively, the patient can be discharged home when the surgeon and the anesthetist are convinced that the condition of the patient is stable. A sensible companion and instruction to the patient that he is not allowed to actively participate in road traffic are essential for discharge after surgery. The decision on outpatient or inpatient care must always be taken individually. It is not possible to make a general statement as to the manner in which an intervention should be carried.
