Awareness under anesthesia

BACKGROUND AND OBJECTIVE: The use of radiotherapy (RT) in the palliative and emergent settings for pediatric cancers is an under-utilized resource. Our objective was to provide an evidence-based review of the data to increase awareness of the benefit for this population along with providing guidance on pediatric specific treatment considerations for palliative care physicians, pediatric oncologists, and radiation oncologists. METHODS: A narrative review was performed querying PubMed, MEDLINE, ClinicalTrials...

PURPOSE: Monitoring of peripheral skin temperature changes is an objective and rapid method to evaluate the success of neuraxial block after spinal anesthesia. The aim of this study is to investigate the effect of prewarming on peripheral temperature changes after the administration of spinal anesthesia. DESIGN: Randomized, prospective, single-blind study. METHODS: In this study, patients scheduled for transurethral resection of the bladder surgery under spinal anesthesia were divided into two groups: those with active prewarming and those without active prewarming...

General anesthesia-a pharmacologically induced reversible state of unconsciousness-enables millions of life-saving procedures. Anesthetics induce unconsciousness in part by impinging upon sexually dimorphic and hormonally sensitive hypothalamic circuits regulating sleep and wakefulness. Thus, we hypothesized that anesthetic sensitivity should be sex-dependent and modulated by sex hormones. Using distinct behavioral measures, we show that at identical brain anesthetic concentrations, female mice are more resistant to volatile anesthetics than males...

Sexual hallucinations are little known, yet often extremely burdening, phenomena. In this systematic review, we summarize what is known about their phenomenology, prevalence, etiopathology, ensuing distress, and treatment options. Sexual hallucinations can be experienced as genital or orgasmic sensations, although other sensory modalities can also be involved. With the notable exception of orgasmic auras in the context of epilepsy, sexual hallucinations tend to be distressing and embarrassing in nature. Our analysis of 79 studies (together describing 390 patients) indicates that sexual hallucinations are more frequent in women than in men, with a sex ratio of 1...

BACKGROUND: Dreaming sometimes occurs during sedation. It has been reported that factors such as different anesthetics, depth of anesthesia, age, sex, and preoperative psychological state may affect dreams. Ciprofol and remimazolam are novel choices for painless endoscopy. Herein, we aimed to investigate dreaming during gastrointestinal endoscopy under propofol, ciprofol, and remimazolam anesthesia respectively. METHODS: This is a prospective, parallel-design double-blind, single-center clinical trial...

BACKGROUND: Nowadays, patients in Thailand have easier access to public health services, resulting in an increased number of patients undergoing surgery. Therefore, the Royal College of Anesthesiologists produces nurse anesthetists to reduce the shortage of anesthesiologists who can perform general anesthesia under the physician's supervision. As a result, nurse anesthetists must have the consciousness to work on the basis of ethics and professional standards. Nurse anesthetists have work experience that aims to benefit patients and make them as safe as possible...

You begin to hear distant rock music playing, people conversing about their weekend. Then the scalpel is requested-incision. Pain sends you reeling and you attempt to muster a scream. No one seems to hear you and you are unable to lift a finger. The scenario is so rare that numerous movies have been made about awareness under anesthesia. Awareness under anesthesia is a rare event, however, it is a complication that no one ever desires to occur. We will explore how frequent awareness is during surgery, what risk factors are involved, and what tools anesthesia providers utilize to ensure everyone undergoing surgery is adequately anesthetized...

The Philips Visual Patient Avatar represents an alternative method of patient monitoring that, according to computer-based simulation studies, enhances diagnostic accuracy and confidence and reduces workload. After its clinical integration, we assessed pediatric anesthesia providers' perspectives on this technology. This is a single-center qualitative study, conducted at the University Hospital Zurich using in-depth individual interviews. We aimed to identify the advantages and limitations of the Visual Patient Avatar in pediatric anesthesia and to assess children's and parents' reactions from caregivers' perspectives...

Pulmonary aspiration of gastric residues during anesthesia is a potentially fatal complication for which no specific treatment is available. The primary way to prevent its occurrence in the context of elective surgeries is adherence to fasting protocols. However, some clinical conditions can prolong the gastric emptying time, and the risk of aspiration may exist despite adequate fasting. Recognizing the risk factors for gastroparesis allows the adoption of preventive methods and is the primary way to reduce morbidity and mortality from pulmonary aspiration...

BACKGROUND: The prevalence of anxiety among patients undergoing arthroscopic surgery and its association with postoperative function has been well documented; however, the level of anxiety and anxiety-related characteristics remain unclear. As such, the present study investigated the characteristics of state anxiety in patients undergoing arthroscopic meniscectomy. METHODS: Data from 75 patients, who underwent arthroscopic partial meniscectomy under general anesthesia and completed an anxiety status questionnaire between April 2021 and March 2022, were retrospectively collected and reviewed...

The electroencephalographic (EEG) activity during anesthesia emergence contains information about the risk for a patient to experience postoperative delirium, but the EEG dynamics during emergence challenge monitoring approaches. Substance-specific emergence characteristics may additionally limit the reliability of commonly used processed EEG indices during emergence. This study aims to analyze the dynamics of different EEG indices during anesthesia emergence that was maintained with different anesthetic regimens...

Delirium is a clinical syndrome characterized by an acute change in attention, awareness and cognition with fluctuating course, frequently observed in older patients during hospitalization for acute medical illness or after surgery. Its pathogenesis is multifactorial and still not completely understood, but there is general consensus on the fact that it results from the interaction between an underlying predisposition, such as neurodegenerative diseases, and an acute stressor acting as a trigger, such as infection or anesthesia...

BACKGROUND: The current fungal meningitis outbreak caused by contaminated epidural anesthesia with Fusarium solani among patients who underwent surgical procedures in Matamoros, Mexico remains a cause of concern. Its association with an increased susceptibility for cerebrovascular complications (CVC) has not been reported. This single-center study describes 3 patients with a unique pattern of CVC attributed to fungal meningitis. METHODS: A retrospective case series of patients diagnosed with fungal meningitis following surgical procedures under contaminated epidural anesthesia who developed a unique pattern of CVC during their hospitalization...

UNLABELLED: Alcohol use disorders (AUDs) are prevalent in intensive care units (ICUs). Alcohol abuse and/or dependence, leading to alcohol withdrawal syndrome (AWS), is as high as 10% or more. There seem to be wide variations in management strategies used to manage these patients, prompting an evaluation of the knowledge gap as well as finding the barriers. Noting lack of such literature in the Indian setting, a survey is undertaken to evaluate practice patterns surrounding the identification and management of alcohol dependence/abuse and AWS in the Indian critical care scenario...

BACKGROUND: Caesarean section (CS) is a major abdominal surgery performed usually on a young and healthy population under neuraxial anesthesia with little to no sedation. This creates a distinct surgical experience whereby patients are aware of the surgical process, physical sensations, and their environment. This study aimed to provide an in-depth descriptive assessment of subjective surgical experience during CS under regional anaesthesia. We expected the information gained would enhance our current understanding and better alleviate patient anxiety through informed counselling...

Although desflurane is a safe and controllable inhalation anesthetic used in spinal surgery, to our knowledge, there have been no reports of successful motor-evoked potential (MEP) recordings under general anesthesia with desflurane alone. A high desflurane concentration may reduce the risk of intraoperative awareness but can also reduce the success of MEP recording. Therefore, we aimed to evaluate the reliability of MEP monitoring and investigate whether tetanic stimulation can augment MEP amplitude under general anesthesia with high-concentration desflurane during spinal surgery...

Pilomatrixoma (PMX), also known as calcifying epithelioma of Malherbe, is a rare benign neoplasm that arises from the hair matrix cells, commonly in the head, neck, and upper trunk regions, infrequently affecting upper and lower extremities. It has to two peaks of presentation: under 20 years of age or between 50 and 65 years of age, slightly more common in females. The neoplasm exhibits diverse clinical manifestations and is frequently subject to misdiagnosis with alternative dermatological diseases. We present an atypical case of PMX affecting the upper extremity of a 62-year-old female patient...

Immunoglobulin A (IgA) deficiency is one of the most common immune disorders characterized by increased susceptibility to infections, especially involving the respiratory tract and mucosal surfaces of the mouth, gingiva, and nasal sinus. Because dental surgery and general anesthesia may pose an increased risk for systemic infections, management of IgA-deficient patients requires caution during dental procedures and intubated general anesthesia. We report a 5-year-old female patient with IgA deficiency who underwent extraction of 18 deciduous teeth under general anesthesia...

BACKGROUND: Medical student involvement in procedures, including pelvic exams under anesthesia (EUAs), is a fundamental part of medical education. While guidelines exist regarding informed consent for medical student participation, there is ongoing debate and uncertainty regarding the requirement and modality of obtaining explicit consent for pelvic EUAs. This study aims to explore the perceptions and experiences of medical students who do not favor an explicit informed consent process for pelvic EUAs...

BACKGROUND: The safety of the male circumcision depends on many factors, including the surgeon, type of anesthesia, and associated complications. The scientific knowledge regarding safe MC is not so prevalent among masses. AIMS AND OBJECTIVES: To study the level of awareness regarding circumcision amongst parents and highlight factors linked to parental satisfaction. MATERIALS AND METHODS: Information regarding various factors was gathered with the help of structured questionnaire-based evaluation of parental knowledge and experience...
