“…3 The junctional rhythm that appeared during general anesthesia in this case was a high nodal rhythm. High nodal junctional rhythm is what appears when the impulse reaches the atrium before the ventricle (P wave preceding the QRS complex).…”

“…[1][2][3] Severe hypotension, however, may occur because of decreased ventricular filling caused by loss of contraction of the atrium (atrial kick) when a low nodal junctional rhythm appears during general anesthesia, especially in association with bradycardia.…”

“…Understanding the cause of a junctional rhythm could lead to more appropriate treatment, if needed. For example, ephedrine or atropine can be used to treat a junctional rhythm in the presence of a slow HR, 3 whereas propranolol or b1-selective blocker (eg, esmolol) may be effective if an accelerated junctional rhythm appears that requires treatment. We therefore believe that it is important to identify the cause of the junctional rhythm prior to treatment, if possible.…”

“…It is diagnosed, usually transiently, in about 20% of patients under general anesthesia. [1][2][3] We report our experience with a case in which junctional rhythm was observed preoperatively and again during general anesthesia. We hypothesize that these episodes were due to different causes.…”

We report a case of junctional rhythm that occurred both preoperatively and later during a portion of general anesthesia. A 19-year-old woman was scheduled to undergo bilateral sagittal split ramus osteotomy after being diagnosed with a jaw deformity. Preoperative electrocardiography (ECG) revealed a junctional rhythm with a slow heart rate (HR). At 90 minutes after anesthesia induction, local anesthesia with 10 mL of 1% lidocaine and 1:100,000 adrenaline was administered. A junctional rhythm appeared 15 minutes after the local anesthesia. We believe that the atrioventricular nodal pacemaker cells accelerated because of the increased sympathetic activity due to the adrenaline. On the preoperative ECG, the junctional rhythm with slow HR appeared as an escaped beat caused by slowing of the primary pacemaker. Therefore, we think that the preoperative junctional rhythm and the junctional rhythm that appeared during general anesthesia were due to different causes. Understanding the cause of a junctional rhythm could lead to more appropriate treatment. We therefore believe that identifying the cause of the junctional rhythm is important in anesthetic management.

“…[26] There is a wide range of other electrophysiological monitoring available to the anaesthetist. Miller's Anesthesia (2009) contain chapters on Cardiovascular Monitoring Schroeder [27], Electrocardiography Hillel [28], Respiratory Monitoring Eskaros [29], Neuromuscular Monitoring VibyMogensen [30] and Temperature Regulation and Monitoring Sessler [31] A problem with all methods of non-clinical electrophysiological scoring of anaesthetic depth is the interindividual variation between the values of different patients during similar clinical depths of anaesthesia and similar strengths of noxious stimulation. Although the mean values for a group of patients may be different at different levels of sedation and stimulation, there may be considerable overlap.…”

Abstract-This paper is a comprehensive literature review on the Depth of Anaesthesia (DoA) monitoring problem. We first investigate the current clinical practice, then briefly introduce the DoA monitors, finally we analyse and discuss the reliability and accuracy of current DoA assessment practice. In this study we find that most of the responses suppressed by anaestheic agents are not of the central nervous system (CNS) but are responses from the peripheral nervous systems (PNS). The responses generated for drug combinations across the therapeutic ranges show considerable variations in drug concentrations that constitute adequate anaesthesia for a particular stimulus. We propose to capture the decision process of anaesthetist using neural networks as neural networks are good at finding patterns in non linear, non stationary signals.
