PURPOSE: Sleep-disordered breathing (SDB) may be a critical risk factor for emergence agitation (EA). We hypothesized that SDB diagnosis is a predictor of EA in children after general anesthesia for ambulatory surgery. DESIGN: Prospective, observational, cohort study. METHODS: Children aged 4 to 17 years were assessed for the occurrence of EA. Differences in probability of EA were assessed using multivariable logistic regression analyses...

BACKGROUND: Patients with Stanford B aortic dissection usually complicated with sleep apnea syndrome. This condition always threatens the patients' respiration situation. In this study, we collected and analysis data of patients' peri-operative managements of Thoracic Endovascular Aortic Repair (TEVAR) for Stanford B Aortic Dissection (AD) complicated with Sleep Apnea Syndrome (SAS). Comparison has been made between these SAS patients and those who without SAS. METHODS: Between June 2013 and June 2014, the clinical data and outcomes of the Stanford B AD patients in the department of vascular surgery in the Second Xiangya Hospital were retrospectively reviewed and studied...

Purpose - Anesthesiologists have increasingly started to use EEG based indexes to estimate the level and type of unconsciousness. However, the physiology and biophysics are poorly understood in anesthesiological literature. Methods - EEG was recorded from electrodes on the surface of head, including scalp, as well as DBS (deep brain stimulation) electrodes implanted deep in the brain. Mathematical modeling with a realistic head model was performed to create illustrative images of the sensitivity of electrode montages...

As the number of procedures being performed in the office based anesthesia (OBA) setting are increasing, so are the number of patients presenting for surgery with obstructive sleep apnea (OSA). There continues to be controversy regarding whether these patients can be safely cared for in the OBA setting. To date, no national guideline has clearly addressed this issue and while some have extrapolated lessons from what has been published for OSA in the ambulatory surgery center (ASC) setting, some argue that there is a significant difference in the availability of resources in the ASC versus the OBA setting...

Macario Camacho, Justin M Wei, Lauren K Reckley, Sungjin A Song
Objectives: During anesthesia emergence, patients are extubated and the upper airway can become vulnerable to obstruction. Nasal trumpets can help prevent obstruction. However, we have found no manuscript describing how to place nasal trumpets after nasal surgery (septoplasties or septorhinoplasties), likely because (1) the lack of space with nasal splints in place and (2) surgeons may fear that removing the trumpets could displace the splints. The objective of this manuscript is to describe how to place nasal trumpets even with nasal splints in place...

Neurofeedback has been around for half a century, but despite some promising results it is not yet widely appreciated. Recently, some of the concerns about neurofeedback have been addressed with functional magnetic resonance imaging and magnetoencephalography adding their contributions to the long history of neurofeedback with electroencephalography. Attempts to address other concerns related to methodological issues with new experiments and meta-analysis of earlier studies, have opened up new questions about its efficacy...

PURPOSE: Practice guidelines from the perianesthesia community suggest that preoperative identification of patients with obstructive sleep apnea (OSA) and standardized longer observation in postanesthesia care unit (PACU) promotes safety after general anesthesia. The purpose of this study was to determine if longer monitoring of patients with OSA in the PACU improves patient outcomes after general anesthesia. DESIGN: Evidence-based best practices literature review...

Study Objectives: Previous research has suggested that general anesthetics can disturb postoperative sleep patterns by affecting the sleep-wake cycle. The objective was to identify the effects of general anesthetics on sleep quality and related behavioral changes in children. Methods: This was a prospective, observational case-control study with children, aged 18 months to 8 years, undergoing general anesthesia for elective surgery. Subjects wore an actigraph for seven days on three occasions: prior to surgery, the immediate postoperative period, and three months after surgery...

PURPOSE: Primary (idiopathic) central sleep apnea (PCSA) is a rare central sleep-related breathing disorder characterized by increased chemoreceptor sensitivity to partial pressure of carbon dioxide, which manifests as hyperventilation followed by apnea during non-rapid eye movement sleep. The purpose of this retrospective study was to describe the postoperative course of patients who had PCSA and underwent procedures requiring anesthetic management. METHODS: Patients who received a diagnosis of PCSA at our institution and required procedural anesthesia between 1 January 2010 and 1 June 2016 underwent a comprehensive review of their health records with a focus on identifying respiratory complications...

Background: Although the positive effects of preoperative oral carbohydrate administration on clinical outcomes following major surgery have been reported continuously, there are few investigations of them in minor surgical patients. The present study was designed to examine the effects of preoperative oral carbohydrate administration on patient well-being and satisfaction in patients undergoing thyroidectomy. Methods: Fifty adults aged 20-65 years and scheduled for elective thyroidectomy in first schedule in the morning were allocated to one of two groups...

The past few years have seen increasing support for gross total resection in the management of low-grade gliomas (LGGs), with a greater extent of resection correlated with better overall survival, progression-free survival, and time to malignant transformation. There is consistent evidence in literature supporting extent of safe resection as a good prognostic indicator as well as positively affecting seizure control, symptomatic relief in pressure symptoms, and longer progression-free and total survival. The operative goal in most LGG cases is to maximize the extent of resection for these benefits while avoiding postoperative neurologic deficits...

PURPOSE: Anesthesia, sedation, and analgesia can negatively impact adult patients with obstructive sleep apnea (OSA). Despite known risks, current evidence, and practice guidelines, insufficient evidence exists that standardization and clinical application of OSA screening tools, problem identification, and perioperative nursing intervention and management strategies are consistently implemented for OSA patients across perianesthesia settings. The purpose of this study was to conduct a knowledge and practice assessment of perianesthesia nurses who care for adult patients with diagnosed or undiagnosed OSA...

Prolonged wakefulness leads to a homeostatic response manifested in increased amplitude and number of electroencephalogram (EEG) slow waves during recovery sleep. Cortical networks show a slow oscillation when the excitatory inputs are reduced (during slow wave sleep, anesthesia), or absent (in vitro preparations). It was recently shown that a homeostatic response to electrical stimulation can be induced in cortical cultures. Here we used cortical cultures grown on microelectrode arrays and stimulated them with a cocktail of waking neuromodulators...

Slow oscillations of neuronal activity alternating between firing and silence are a hallmark of slow-wave sleep (SWS). These oscillations reflect the default activity present in all mammalian species, and are ubiquitous to anesthesia, brain slice preparations, and neuronal cultures. In all these cases, neuronal firing is highly synchronous within local circuits, suggesting that oscillation-synchronization coupling may be a governing principle of sleep physiology regardless of anatomical connectivity. To investigate whether this principle applies to overall brain organization, we recorded the activity of individual neurons from basal ganglia (BG) structures and the thalamocortical (TC) network over 70 full nights of natural sleep in two vervet monkeys...

It is important for academic-minded human anesthesiologists to have an interdisciplinary perspective when engaging in cutting-edge research as well as the practice of human anesthesiology. This was a philosophy promoted by Dr. Robert Dripps, former pioneering Chairman of the Anesthesiology Department at the University of Pennsylvania (Philadelphia, Pennsylvania). Many human and veterinary anesthesiologists as well as biomedical engineers and neuroscientists benefited from Dr. Dripps's constructive outlook personified in the quest to develop dolphin anesthesiology...

Postoperative cognitive dysfunction (POCD) is a common clinical phenomenon characterized by cognitive deficits in patients after anesthesia and surgery. Advanced age is a significant independent risk factor for POCD. We previously reported that in young mice, sleep-wake rhythm is involved in the isoflurane-induced memory impairment. In present study, we sought to determine whether advanced age increased the risk of POCD through aggravated and prolonged post-anesthetic circadian disruption in the elderly. We constructed POCD model by submitting the mice to 5-h 1...

OBJECTIVES: The glymphatic system is a recently hypothesized waste clearance system of the brain in which perivascular space constitutes a pathway similar to the lymphatic system in other body regions. Sleep and anesthesia are reported to influence the activity of the glymphatic system. Because rats are nocturnal animals, the glymphatic system is expected to be more active during the day. We attempted to elucidate the influence of the glymphatic system for intravenously injected gadodiamide in the rat brain by 2 experiments...

Patients with sleep apnea are prone to postoperative respiratory complications, requiring restriction of sedatives during perioperative care. We performed a prospective randomized study on 24 patients with obstructive sleep apnea (OSA) who underwent elective surgery under general anesthesia. The patients were equally divided into two groups: Group Dex : received dexmedetomidine loading dose 1 mcg/kg IV over 10 min followed by infusion of 0.2-0.7 mcg/kg/hr; Group KFL : received ketofol as an initial bolus dose 500 mcg/kg IV (ketamine/propofol 1 : 1) and maintenance dose of 5-10 mcg/kg/min...

Introduction: The importance of obstructive sleep apnea in patients undergoing surgery with general anesthesia is well-defined, but the surgical and anesthetic implications of other sleep disorders are less clear. We sought to evaluate response to surgery with general anesthesia in patients with central disorders of hypersomnolence or restless legs syndrome. Methods: We surveyed patients on their most recent surgical procedure with general anesthesia, querying about procedure, recovery, and any changes in sleep disorder symptomatology following the procedure...
