Abstract
Purpose of Review
Automated control of anesthesia may give the physician time to control hemodynamics and supervise neurological outcomes and thus can provide the patient the safety and quality which until recently was considered a holy grail.
Recent Findings
This field of research is now increasing in every component of general anesthesia (hypnosis, nociception, neuromuscular blockade), and the literature describes some successful algorithms—single or multi-closed-loop controllers. These devices aim to control a predefined target and to continuously titrate anesthetics whatever the patients’ co-morbidities and surgical events to reach this target.
Summary
The literature contains many randomized trials comparing manual and automated anesthesia and shows the feasibility and safety of this system. Automation could quickly concern other aspects of anesthesia like fluid or vasopressor management. This review proposes an overview of closed-loop systems in anesthesia.

Anesth Analg. 2017;124:446–55. This meta-analysis written by specialists in automated anesthesia gives a good focus on the definitions and the goals to achieve with automated anesthesia compared to manual administration. The use of automated systems results in better control of a target within a selected range with a reduction of overshooting or undershooting. The authors described also the limits of the system.

This study is ancillary to a randomized control trial on automated versus standard anesthesia (induction and maintenance) but it introduced the relationship between general anesthesia and especially total IV anesthesia with systematic brain monitoring and the cerebral outcome. If it was previously supposed, this is the first confirmation with psychometric tests.
