Spectral edge frequency during general anaesthesia: A narrative literature review.

Previous studies have attempted to determine the depth of anaesthesia with different anaesthetic agents using electroencephalogram (EEG) measurements with variable success. Measuring depth of anaesthesia is confounded by the complexity of the EEG and the fact that different agents create different pattens. A narrative review was undertaken to examine the available research evidence on the effect and reliability of spectral edge frequency (SEF) for assessing the depth of anaesthesia in adult patients under general anaesthesia.

Agreement between frontal and occipital regional cerebral oxygen saturation in infants during surgery and general anesthesia an observational study.

Background: Advances in perioperative pediatric care have resulted in an increased number of procedures requiring anesthesia. During anesthesia and surgery, the patient is subjected to factors that affect the circulatory homeostasis, which can influence oxygenation of the brain. Near-infrared spectroscopy (NIRS) is an easy applicable noninvasive method for monitoring of regional tissue oxygenation (rScO₂%).

At-home monitoring after surgery/anaesthesia - a challenge.

Rationale, Aims And Objectives: Day surgery is evolving, with a majority of recoveries occurring at home. There is, in parallel, an evolution in telemedical technology. The aim of the present project was to identify patients' willingness to use predefined follow-up techniques and to clinically test preferred techniques at home using a two-step study.

Assessment of post-operative pain management among acutely and electively admitted patients - a Swedish ward perspective.

Rationale, Aims And Objectives: Swedish health care is regulated to involve the patient in every intervention process. In the area of post-operative pain, it is therefore important to evaluate patient experience of the quality of pain management. Previous research has focused on mapping this area but not on comparing experiences between acutely and electively admitted patients.

Brief review: theory and practice of minimal fresh gas flow anesthesia.

Purpose: The aim of this brief review is to provide an update on the theory regarding minimal fresh gas flow techniques for inhaled general anesthesia. The article also includes an update and discussion of the practical aspects associated with minimal-flow anesthesia, including the advantages, potential limitations, and safety considerations of this important anesthetic technique.

Principal Findings: Reducing the fresh gas flow to < 1 L·min(-1) during maintenance of anesthesia is associated with several benefits.
