Bloqueo del plano transverso abdominal para control del dolor intra y posoperatorio en herniorrafia inguinal en paciente con síndrome de Brugada / Block of transverse abdominal pain for intra-and posoperative pain control in inguinal herniorrhaphy in patient with Brugada syndrome

Los pacientes con síndrome de Brugada suponen un reto desde el punto de vista anestésico ya que son muchas las circunstancias perioperatorias y los fármacos que pueden desencadenar una crisis arritmogénica, los cuales pueden llegar a tener un fatal desenlace. Las implicaciones anestésicas en estos pacientes son múltiples por lo que se debe ser muy cuidadoso y tener en cuenta muchos factores. Se exponen las consideraciones y el manejo anestésico que se realizó en un paciente con síndrome de Brugada sometido a una herniorrafía inguinal izquierda en la que se opta por la realización de una anestesia general junto con un bloqueo ecoguiado del plano transverso abdominal para control de dolor(AU)

Patients with Brugada syndrome are a challenge from the anesthetic point of view, since there are many perioperative circumstances and drugs that can trigger an arrhythmogenic crisis, which can have a fatal outcome. Anesthetic implications in these patients are multiple, a reason why one must be very careful and take into account many factors. The considerations and anesthetic management are described for the case of a patient with Brugada syndrome who underwent left inguinal herniorrhaphy, in which general anesthesia was chosen together with ultrasound-guided block of transverse abdominal plane for pain control(AU)

Maternity Nurses' Knowledge about Sudden Unexpected Postnatal Collapse and Safe Newborn Positioning.

PURPOSE: Sudden unexpected postnatal collapse (SUPC) of healthy newborns in the first 2 days of life is increasing. These types of adverse events are known to be associated with unsafe positioning during skin-to-skin contact and breastfeeding. The purpose of the study was to determine maternity nurses' knowledge about SUPC and safe newborn positioning. DESIGN: Nurses who participate in a hosted listserv were solicited to complete a questionnaire. METHODS: An email with an embedded link to a 20-item questionnaire, the SUPC and Safe Positioning Knowledge Assessment Tool, and 16 demographic questions was sent to 605 maternity nurses in the United States who are part of a Perinatal Listserv for members of the Association of Women's Health, Obstetric and Neonatal Nurses. Scores were analyzed by mean, standard deviation, and percent correct answers. RESULTS: Fifty questionnaires were initiated (response rate of 8.2%), and 36 completed questionnaires (response rate of 5.9%) were analyzed. Maternity nurses' knowledge of SUPC was less than their knowledge of safe newborn positioning (61% correct vs. 72% correct; p < 0.001). CLINICAL IMPLICATIONS: Maternity nurses need more information about SUPC and safe newborn positioning, including risk factors, and effective strategies to reduce risk of preventable newborn harm.

Nurses Leading Safe Infant Sleep Initiatives in the Hospital Setting.

Every day, 10 otherwise healthy infants die from sleep-related deaths in the United States. These deaths, termed sudden unexpected infant death, remain the leading cause of post-neonatal death in the United States despite known modifiable risk factors and prevention recommendations. In birthing hospitals, many parents report being given incorrect and sometimes no information about infant sleep safety, which creates immediate and long-term safety concerns. In this article, we provide an overview of sudden unexpected infant death, including sudden unexpected postnatal collapse, and the latest safe sleep recommendations from the American Academy of Pediatrics. We also offer practical guidelines for nurses-those working at the bedside and those in leadership positions-who may be seeking to improve the quality of infant sleep practices in their organizations.

Understanding the Risks Sitting and Carrying Devices Pose to Safe Infant Sleep.

There have been various campaigns and recommendations to decrease the incidence of sudden unexpected infant death. Despite this, caregivers continue to place infants in unsafe sleeping environments. These environments, such as sitting devices, slings, carriers, and car seats, pose a significant risk to an infant's safety because of the risk from suffocation and cardiorespiratory instability. It is important for health care providers to understand the appropriate use of car seats, slings, and other sitting devices, to model appropriate behaviors, and to educate parents and caregivers. All parents, hospital staff, and other caregivers should understand the potential dangers associated with the inappropriate use of sitting devices for routine sleep.

Cardiac sodium channels and inherited electrophysiological disorders: an update on the pharmacotherapy.

INTRODUCTION: Since the recognition of inherited sodium (Na(+)) channel disease, the cardiac Na(+) channel has been extensively studied. Both loss-of-function and gain-of-function mutations of the cardiac Na(+) channel are associated with cardiac arrhythmia and sudden cardiac death. Pathophysiological mechanisms that may induce arrhythmia are unravelled and include alterations in biophysical properties due to the mutation in SCN5A, drug use and circumstantial factors. Insights into the mechanisms of inherited Na(+) channel disease may result in tailored therapy. However, due to the complexity of cardiac electrical activity and pathophysiological mechanisms, pharmacotherapy in cardiac Na(+) channel disease remains challenging. AREAS COVERED: This review discusses various mechanisms involved in inherited Na(+) channel disorders, focussing on Brugada syndrome (Brs) and long QT syndrome type 3 (LQTS3). It aims to provide an overview of developments in pharmacotherapy, discussing both treatment and which drugs to avoid to prevent arrhythmia. EXPERT OPINION: Altered biophysical properties of cardiac Na(+) channels are the basis of arrhythmias in patients with inherited Na(+) channel diseases such as BrS and LQTS3. The effects of such biophysical derangements are strongly modulated by concomitant factors. Tailored drug therapy is required to prevent arrhythmia and is best achieved by educating patients affected by Na(+) channel disorders.

The usual suspects in sudden cardiac death of the young: a focus on inherited arrhythmogenic diseases.

Up to 14,500 young individuals die suddenly every year in Europe of cardiac pathologies. The majority of these tragic events are related to a group of genetic defects that predispose the development of malignant arrhythmias (inherited arrhythmogenic diseases [IADs]). IADs include both cardiomyopathies (hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, dilated cardiomyopathy) and channelopathies (long QT syndrome, short QT syndrome, Brugada syndrome and catecholaminergic polymorphic ventricular tachycardia). Every time an IAD is identified in a patient, other individuals in his/her family may be at risk of cardiac events. However; if a timely diagnosis is made, simple preventative measures may be applied. Genetic studies play a pivotal role in the diagnosis of IADs and may help in the management of patients and their relatives.

Remote monitoring of a high-risk patient with Brugada syndrome: association of different arrhythmic manifestations.

We report on the remote arrhythmia monitoring of a 34-year-old man with highly symptomatic Brugada syndrome, who initially presented with syncope, paroxysmal atrial fibrillation, and spontaneous coved-type electrocardiogram. The patient received a dual-chamber implantable cardioverter-defibrillator (ICD) with Home Monitoring™ facilities and experienced recurrent ICD shocks for spontaneous ventricular fibrillation (VF) episodes during the first year after ICD implantation. Remote monitoring revealed an increased burden of premature ventricular complexes and atrial arrhythmias each time VF spontaneously occurred. Atrial and ventricular arrhythmias were effectively suppressed by low-dose quinidine without severe side effects.

Drug-induced Brugada syndrome by noncardiac agents.

Drug-induced Brugada syndrome (BrS) represents a great challenge for the prescribing clinicians as well as for those involved in the development of novel pharmaceuticals and in the regulatory bodies responsible with monitoring drug safety. Apart from well-known cardiac agents (mainly Class I antiarrhythmics), an increasing number of noncardiac agents, including psychotropic and anesthetic drugs, have been shown to induce the characteristic Brugada electrocardiogram pattern predisposing to fatal ventricular arrhythmias. Up to now, both repolarization and depolarization abnormalities are thought to be related to the development of ventricular fibrillation in BrS patients. This review highlights the mechanisms and the noncardiac medical agents that unmask a genetic predisposition to BrS.

First clinical manifestation of Brugada syndrome during pregnancy.

The role of hormonal changes during pregnancy in Brugada syndrome is unknown. Only rare case reports of Brugada syndrome during pregnancy have been published. In this article, we describe a patient with first clinical manifestation of Brugada syndrome during pregnancy. The definitive diagnosis could only be achieved by drug challenge with ajmaline after childbirth because the spontaneous typical Brugada-like pattern was absent. Elevated hormone levels during pregnancy may increase the risk for arrhythmias in particular cases.

Role of home monitoring in children with implantable cardioverter defibrillators for Brugada syndrome.

AIMS: Implementation of remote home monitoring systems (HM) in clinical practice has become undoubtedly an added value for all patients with implantable cardiac devices. The aim of this study was to investigate the impact of HM in a population of children with Brugada syndrome (BS) who received an implantable cardioverter defibrillator (ICD). METHODS AND RESULTS: Eleven children (age between 6 months and 18 years) implanted with an ICD were followed either by means of HM and with conventional in-hospital visits in our centre. Alerts and/or device-related clinical events were recorded, analysed, and subsequent clinical decisions were made if needed. During an average observation time of 26 months a total of 16 relevant alerts (13 pre-emptive alerts) were recorded in seven patients of our population. One patient experienced appropriate therapies for life-threatening ventricular arrhythmias. Three patients experienced inappropriate therapies due to supraventricular tachycardia and lead dislodgement. By means of HM two patients were discovered to have lead problems because of dislodgement or lead fracture. Mean anticipation of treatment based on the alerts was 76 ± 59 days. CONCLUSION: Remote monitoring systems substantially improve the proper management of children with BS.

Non-EEG seizure-detection systems and potential SUDEP prevention: state of the art.

PURPOSE: There is a need for a seizure-detection system that can be used long-term and in home situations for early intervention and prevention of seizure related side effects including SUDEP (sudden unexpected death in epileptic patients). The gold standard for monitoring epileptic seizures involves video/EEG (electro-encephalography), which is uncomfortable for the patient, as EEG electrodes are attached to the scalp. EEG analysis is also labour-intensive and has yet to be automated and adapted for real-time monitoring. It is therefore usually performed in a hospital setting, for a few days at the most. The goal of this article is to provide an overview of body signals that can be measured, along with corresponding methods, state-of-art research, and commercially available systems, as well as to stress the importance of a good detection system. METHOD: Narrative literature review. RESULTS: A range of body signals can be monitored for the purpose of seizure detection. It is particularly interesting to include monitoring of autonomic dysfunction, as this may be an important patho-physiological mechanism of SUDEP, and of movement, as many seizures have a motor component. CONCLUSION: The most effective seizure detection systems are multimodal. Such systems should also be comfortable and low-power. The body signals and modalities on which a system is based should take account of the user's seizure types and personal preferences.

Safe drug use in long QT syndrome and Brugada syndrome: comparison of website statistics.

AIMS: We sought to obtain insights into the efficacy of two websites, www.QTdrugs.org and www.BrugadaDrugs.org, that have the intention to prevent fatal arrhythmias due to unsafe drug use in Long QT syndrome and Brugada syndrome. METHODS AND RESULTS: Prospective web-use statistical analysis combined with online surveys were employed. Our main outcome measure was the percentage of Long QT syndrome patients and Brugada syndrome patients reporting refraining or discontinuation of possible unsafe drugs. QTdrugs.org has received >3 100 000 visitors from 180 countries. Most visitors originated from the Americas (87%), as compared with Europe (7%), Asia (3%), Oceania (2%), and Africa (1%). The QTdrugs.org survey yielded 340 respondents: 34% were patients and 50% medical professionals. Of the patients, 79% reported that they refrained from, and 61% reported discontinuing drugs due to the website. The website was very much appreciated by 65% of the respondents and 30% found it rather helpful. The BrugadaDrugs.org received >48 000 visitors from 154 countries. Most visitors originated from Europe (46%) and the Americas (39%), but less from Asia (10%), Oceania (4%), and Africa (<1%). The BrugadaDrugs.org survey yielded 178 respondents: 68% were patients and 21% medical professionals. Of the patients, 72% reported refraining from, and 48% discontinuing drugs due to the website. The website was very much appreciated by 72% of the respondents and 25% found it rather helpful. CONCLUSION: These websites are extensively used, they promote drug awareness, and they help patients to avoid possible pro-arrhythmic drugs. Visitors find the websites valuable but should note their limitations.
