PURPOSE: to describe the characteristics of the color density spectral array (CDSA) of bilateral bispectral index (b-BIS) monitoring system in patients with comatose nonconvulsive status epilepticus (NCSE). We hypothesized that CDSA could be helpful for monitoring NCSE in critically subjects if continuous EEG (cEEG) is not available. METHODS: we retrospectively analyzed comatose patients admitted to our neurological intensive care unit (NICU) from 2011 to 2014 with a diagnosis of definitive NCSE that underwent b-BIS monitoring for at least 24h to guide anesthetic sedation...

OBJECTIVES: Electroconvulsive therapy (ECT) has dramatically reduced musculoskeletal complications when carried out with muscle relaxants under general anesthesia. However, seizure quality can be affected by the depth of anesthesia and choice of anesthetic agent. The purpose of this study was to describe a general anesthetic technique for ECT by using laryngeal mask, bispectral index (BIS), and muscle relaxant monitoring. METHODS: Twenty-one patients, between ages 18 and 70 years (American Society of Anesthesiologists physical status I-III), who underwent a total of 89 sessions of ECT were examined in a retrospective study...

INTRODUCTION: Many patients with a traumatic brain injury (TBI) cannot communicate because of altered level of consciousness. Although observation of pain behaviors (e.g., frowning) is recommended for pain assessment in nonverbal populations, they are attenuated and sometimes even suppressed in patients with TBI receiving high doses of sedatives. This study explored the potential utility of the bilateral bispectral index system (BIS) for pain detection in critically ill adults with TBI and altered level of consciousness...

BACKGROUND: Postoperative delirium (POD) occurs frequently after cardiac surgery and is associated with increased morbidity and mortality. We analysed whether perioperative bilateral BIS monitoring may detect abnormalities before the onset of POD in cardiac surgery patients. METHODS: In a prospective observational study, 81 patients undergoing cardiac surgery were included. Bilateral Bispectral Index (BIS)-monitoring was applied during the pre-, intra- and postoperative period, and BIS, EEG Asymmetry (ASYM), and Burst Suppression Ratio (BSR) were recorded...

BACKGROUND: Use of transversus abdominis plane (TAP) block for postoperative analgesia is continuously increasing. However, few studies have investigated intraoperative effects of TAP block. We aimed to study the effects of TAP block in terms of cost-effectiveness and consumption of inhalation agents. MATERIAL AND METHODS: Forty patients undergoing laparoscopic cholecystectomy were enrolled in this study. Patients were randomly divided into 2 groups: Group 1 (n=20) patients received TAP block and Group 2 (n=20) patients did not receive TAP block...

A 54-year-old woman with a history of severe tracheal stenosis caused by papillary thyroid cancer with tracheal invasion was admitted for an elective surgery. A bilateral superficial cervical plexus block with 0.5 % ropivacaine 14 ml (7 ml per side) under dexmedetomidine sedation was performed, followed by tracheal dissection and endotracheal tube (ETT) insertion. The patient continued spontaneous respiration without any hypoxic event, and the bispectral index was maintained at a range of 50-80. After ETT insertion, a total thyroidectomy and tracheal resection with end-to-end anastomosis were performed under general anesthesia...

PURPOSE: A variety of hemodynamic and respiratory alterations accompany patients in the prone position; however the effect of the prone position on intraoperative cerebral saturation has not been studied. We sought to examine whether the incidence of cerebral oxygen desaturation in elderly patients (≥68 years of age) undergoing spine surgery in the prone position was more common than patients undergoing major surgery in the supine position. METHODS: We performed a retrospective cohort study of 205 patients; 63 patients underwent surgery in the prone position and 142 in the supine position...

The Wada test is a procedure used in the preoperative assessment before epilepsy surgery in order to determine language lateralization, to assess the post-operative risk of an amnesia syndrome, and to evaluate the risk of material-specific memory deficits, in particular verbal memory deficits. This test involves inserting a cannula into the internal carotid artery via the femoral artery, and then to inject amobarbital to shut down brain function, usually in one of the brain hemispheres. The bilateral bispectral index (BIS) VISTA™ monitoring system (BVMS) was used to detect changes in EEG, and in the power spectrum distribution using the density spectral array (DSA) of both hemispheres...

COMPARATIVE STUDY
M Soehle, S Kayser, R K Ellerkmann, T E Schlaepfer
BACKGROUND: Electroconvulsive therapy (ECT) is a highly effective and established treatment for depression. Magnetic seizure therapy (MST) has recently been developed and seems equally effective while associated with fewer side-effects. Both require general anaesthesia, which could be quantified using the bispectral index (BIS). We compared ECT and MST with respect to recovery times, left-sided BIS, and left-right differences in BIS. METHODS: In this prospective, observational study, we enrolled 10 successive patients receiving ECT and 10 patients undergoing MST...

BACKGROUND: The influence of frontal brain tumours on bispectral index (BIS) measurements and propofol requirements is unknown. The primary aim of our study was to determine whether BIS values recorded at loss and return of consciousness (LOC and ROC, respectively) differ between patients with unilateral frontal brain tumours and control patients. Secondary goals were to compare propofol requirements for LOC and to determine whether there were significant inter-hemispheric differences between BIS values in tumour and control patients...

Earlier diagnosis of cerebral vasospasm and delayed cerebral ischemia (DCI) and treatment has the potential to decrease post-bleed morbidity after subarachnoid hemorrhage (SAH). Previous studies have shown that electroencephalogram (EEG) can detect blood flow changes associated with DCI sooner than other modalities potentially leading to earlier diagnosis. However, continual monitoring with raw EEG requires significant expertise and effort, and may be difficult due to the intermittent need for MRI studies in these patients...

A 55-year-old male with Lambert-Eaton myasthenic syndrome underwent low anterior resection. Before anesthetic induction, his arterial blood gas analysis showed chronic hypercapnia (pH 7.404, Paco2 59 mmHg, BE 9.1). Anesthesia was induced with propofol, remifentanil and ketamine. Uneventful tracheal intubation was achieved after superior laryngeal nerve block without using muscle relaxants. Then ultrasound-guided bilateral rectus sheath block and transversus abdominis plane block were performed using 60 ml of 0...

Movement responses to noxious stimuli during anaesthesia indicate nociception. Under experimental conditions consistent prediction of such movement responses has been achieved by the use of nociceptive flexion reflexes (NFRs). The aim of this study was to investigate the reliability of NFRs and the electroencephalogram bispectral index (BIS) in predicting motor responses to real surgical stimuli in pigs. The study was undertaken in 30 pigs undergoing bilateral orchiectomy under ketamine/azaperone anaesthesia...

We report the case of a patient with an extensive right cerebral hematoma complicated by focal nonconvulsive status epilepticus (NCSE) in whom the use of the new bilateral BIS-Vista™ monitor was helpful in managing profound sedation and antiepileptic treatment in the absence of continuous EEG monitoring (CEEG). The analysis of color density spectral array (CDSA) showed stereotyped changes indicative of recurrent focal nonconvulsive seizures (NCSz) and NCSE. We noted a close correlation between NCSz and BIS value changes...
