Perioperative Management of Painful Phantom Limb Syndrome: A Narrative Review and Clinical Management Proposal.

OBJECTIVE: Painful Phantom Limb Syndrome (PPLS) occurs in 50 to 80% of patients undergoing amputation, having a great impact on quality of life, productivity and psychosocial sphere. The objective of this review is to summarize the pharmacological and non-pharmacological strategies, surgical optimization, and provide a multidisciplinary approach aimed at reducing the incidence of chronic pain associated with PPLS in patients undergoing limb amputation. METHODS: A narrative review was carried out using Medline, Pubmed, Proquest, LILACS and Cochrane, searching for articles between 2000 and 2021. Articles describing the epidemiology, pathophysiological considerations, and current treatments were selected after a screening process. RESULTS: A multidisciplinary and multimodal approach is required in PPLS, and should include the use of regional techniques, and adjuvants such as NSAIDs, ketamine, lidocaine and gabapentinoids. In addition, an evaluation and continuous management of risk factors for chronic pain in conjunction with the surgical team is necessary. CONCLUSION: The current literature does not support that a single technique is effective inthe prevention of PPLS. However, adequate acute pain control, rehabilitation and early restoration of the body scheme under a multidisciplinary and multimodal approach have shown benefit in the acute setting.

Analgesic Treatment Approach for Postherpetic Neuralgia: A Narrative Review.

Post-herpetic neuralgia (PHN) is an entity derived from peripheral nerve damage that occurs during the reactivation of the Varicella Zoster Virus (VZV), which manifests itself through pain with neuropathic characteristics. This can prove to be very difficult to manage in the chronic stages of disease reappearance. There currently exists a multitude of treatment alternatives for PHN, however, prevention through the early initiation of antiviral regimens is vital. There are various pharmacological options available, but it is important to individualize each patient to maximize efficacy and minimize adverse effects. Interventional procedures have become a cornerstone in difficult-to-manage cases, and have shown promising outcomes when used in a multimodal approach by experienced specialists. It is necessary to make an objective diagnosis of PHN and start early treatment. Additionally there is current evidence that vouches for interventional therapies as well as individualization, with a clear establishment of therapeutic objectives according to the needs of each patient.

The role of local inflammation in complications associated with intubation in pediatric patients: A narrative review.

Although the most important primary local inflammatory response factor to intubation is not yet clear, it is known that it may be directly attributed to the presence of trauma during intubation or the response of oral bacterial flora present in the trachea. It is known that prolonged intubation is associated with worse outcomes, but other underlying systemic issues, such as sepsis and trauma, are also associated with this result. Likewise, patients who require advanced airway management and excessive manipulation are more likely to experience complications. There are various inflammatory mediators that are generated during orotracheal intubation, many of which can be considered targets for therapies to help reduce inflammation caused by intubation. However, there is little evidence on the management of the inflammatory response induced by orotracheal intubation in pediatric patients. Therefore, the aim of this narrative review is to highlight the intubation associated complications that can arise from poorly controlled inflammation in intubated pediatric patients, review the proposed pathophysiology behind this, and discuss the current treatments that exist. Finally, taking into account the discussion on pathophysiology, we describe the current therapies being developed and future directions that can be taken in order to create more treatment options within this patient population.

Cardiovascular effects of hyoscine butylbromide in patients under general anaesthesia.

BACKGROUND: Cardiovascular effects for drugs such as hyoscine butylbromide are poorly documented in the literature, unlike atropine, which is considered the antimuscarinic of choice in the presence of intraoperative bradycardia. AIM: The aim of the study was to describe the dose-related cardiovascular effect of hyoscine butylbromide in patients between 18 and 65 years of age, with low perioperative risk undergoing elective surgery under general anaesthesia on an outpatient basis or hospitalised at our institution between 1 January and 31 May 2019. METHODS: Descriptive, cross-sectional, retrospective study; 28 patients with low perioperative risk who underwent general anaesthesia were selected. Changes in heart rate and blood pressure were analysed during the first 6 minutes after the administration of hyoscine butylbromide. The data obtained was recorded in a Microsoft Excel database and analysed using the Excel analysis tool and IBM SPSS. RESULTS: The average dose of 0.15mg/kg of hyoscine butylbromide achieved an increase in heart rate and mean arterial pressure in 96% and 92.8%, respectively, in the first 6 minutes after the administration. Significant changes in heart rate and blood pressure were obtained during the first 6 minutes at doses between 0.05mg/kg and 0.15mg/kg. CONCLUSION: Hyoscine butylbromide generates positive effects on the heart rate and blood pressure of patients under general anaesthesia, representing a possible alternative in the management of intraoperative bradycardia.

Impact of the SARS-CoV-2 pandemic on Colombian anesthesiologists: Survey study / Impacto de la pandemia por SARS-CoV-2 en anestesiólogos colombianos. Estudio de encuesta

Abstract Introduction: The practice of anesthesiology during the COVlD-i9/SARS-CoV-2 pandemic has had a psychological impact, and has been associated with ethical dilemmas, work overload, and occupational risk. Objective: To understand different problems affecting anesthesiologists, in particular with regards to professional ethics in the decision-making process, increased personal workload, and the potential risk in terms of their own safety and health, as a consequence of working during the COVlD-19 pandemic. Methods: Observational, descriptive, cross-sectional study. A survey was administered to anesthesiologists members of the Colombian Society of Anesthesiology and Resuscitation (S.C.A.R.E.), to enquire about work hours, occupational safety, prevention standards and strategies, and ethical aspects involved in decision making during the COVID-19 pandemic. Results: 218 anesthesiologist participated in the survey. Most of the respondents felt that there was not a significant increase in their workload, except for those in critical care (42.5 %; n = 17). Most of the participants believe that leisure time is not enough. 55.96 % (n = 122) of the participants said they felt moderately safe with the biosecurity measures, but with a higher risk of contagion versus other practitioners, with 72.9 % (n = 159) responding that they used their own money to buy personal protection equipment (PPE). There was also evidence that one fourth of the respondents has faced ethical dilemmas during the resuscitation of SARS-CoV-2 - infected patients. Conclusions: The information gathered is a preliminary approach to the situation arising in Colombia as a result of the pandemic; it is clear that anesthesiologists perceive higher associated lack of safety due to different factors such as higher risk of infection, shortage of PPEs and burnout, inter alia. Hence we believe that it is fundamental to acknowledge the work of all anesthesiologists and understand the impact that the pandemic has had on this group of professionals.

Resumen Introducción: El ejercicio de la anestesiología durante la pandemia por COVID-i9/SARS-CoV-2 ha tenido un impacto psicológico y ha estado asociado a dilemas éticos, aumento en la sobrecarga y riesgo laboral. Objetivo: Comprender distintos problemas en los que se han visto envueltos los médicos anestesiólogos, en especial los relacionados con su ética profesional en el proceso de tomar decisiones, el aumento en la carga personal y el posible riesgo de su seguridad y salud como consecuencia de su labor durante la pandemia por COVID-19. Métodos: Estudio observacional, descriptivo, de corte transversal. Por medio de una encuesta, aplicada a anestesiólogos afiliados a la Sociedad Colombiana de Anestesiología y Reanimación (S.C.A.R.E.), se indagó acerca de jornadas laborales, seguridad laboral, normas y estrategias de prevención, y aspectos éticos vinculados con la toma de decisiones durante la pandemia por COVID-19. Resultados: Participaron 218 anestesiólogos. La mayoría de los encuestados consideró que no hubo aumento significativo en su carga laboral, excepto aquellos que ejercen en cuidado crítico (42,5 %; n = 17). La mayoría de los participantes consideran que el tiempo de descanso no es suficiente. Un 55,96 % (n = 122) de los participantes, refieren sentirse moderadamente seguros con las medidas de bioseguridad, pero con un mayor riesgo de contagio frente a otros profesionales, con un 72,9 % (n = 159) y manifestaron haber invertido de sus propios recursos para la adquisición de elementos de protección personal (EPP). Así mismo, se evidenció que una cuarta parte de los entrevistados se ha enfrentado a dilemas éticos durante la reanimación de pacientes infectados por SARS-CoV-2. Conclusiones: La información obtenida hace un acercamiento inicial a la problemática generada en Colombia por la pandemia, donde es evidente que los anestesiólogos perciben una mayor inseguridad asociada, debido a diversos factores como mayor riesgo de infección, insuficiencia de EPP y burnout, entre otros. Por ende, creemos que es fundamental reconocer el trabajo de todos los anestesiólogos, y comprender el impacto que la pandemia ha tenido en estos profesionales.

Stellate ganglion block as an analgesic rescue alternative in phantom limb syndrome following an amputation: A case report / Bloqueo del ganglio estrellado como alternativa de rescate analgésico en síndrome de miembro fantasma doloroso postamputational: Un reporte de caso

Phantom limb syndrome (PLS) is a condition that occurs in amputee patients that has a wide array of different treatment approaches. We present the case of a patient diagnosed with complex regional pain syndrome (CRPS) of the right upper limb secondary to polytrauma with complete brachial plexus injury, who, after being subjected to multiple successful therapies, was finally taken to amputation. Later, he developed a painful PLS that was difficult to manage, which was treated with a stellate ganglion block (SGB), achieving a significant decrease in pain. This article aims to present a case in which a SGB was used as an adjunct to control acute postoperative PLS in a patient with previous sensitization due to CRPS. The SGB, in this case, performed with local anesthetic plus corticosteroid, constitutes a useful therapeutic alternative for intense postoperative pain in PLS, achieving adequate pain relief without adverse effects. However, its routine use as in acute postoperative pain still lacks sufficient evidence for complete support, therefore we urge the scientific community to undertake more in-depth research concerning this topic in order to create clear guidelines and recommendations.

El síndrome del miembro fantasma (PLS, por sus siglas en inglés) es una condición que se presenta en pacientes amputados con un campo extenso para los diferentes enfoques de tratamiento. Presentamos el caso de un paciente diagnosticado con síndrome complejo de dolor regional (SCDR) del miembro superior derecho secundario a politraumatismo con lesión completa del plexo braquial, quien, tras ser sometido a múltiples tratamientos exitosos, fue finalmente llevado a amputación. Posteriormente, desarrolló un PLS doloroso de difícil manejo, el cual fue tratado con un bloqueo del ganglio estrellado (BGE), logrando una disminución significativa del dolor. Este artículo tiene como objetivo presentar un caso en el que se utilizó un BGE como coadyuvante para el control del PLS en el posoperatorio de manera aguda en un paciente con sensibilización previa por SCDR. EL BGE, en este caso, realizado con anestésico local más corticosteroide, constituye una alternativa terapéutica útil para el dolor posoperatorio intenso en PLS, consiguiendo un adecuado alivio del dolor sin efectos adversos. Sin embargo, su uso rutinario como en el dolor postoperatorio agudo, aún carece de evidencia suficiente para un respaldo completo, por lo que invitamos a la comunidad científica a realizar una investigación más profunda sobre este tema para crear pautas y recomendaciones claras.

Actualización en el manejo preoperatorio en pacientes con hipotiroidismo / Preoperative management of patients with hypothyroidism: An update

The preoperative management of patients with hypothyroidism has an impact on the clinical outcomes in the postoperative period, however, it has been found that there is a lack of evidence regarding management recommendations in this scenario. Therefore, we conducted a review of the literature for articles in English and Spanish from the years 2000 to 2020 in the databases PubMed, ProQuest, Scopus and Embase, that highlight the physiology, pathophysiology and current recommendations for preoperative management in this patient population. It is of great importance to understand the physiological changes and implications in the anesthetic management of these patients, in order to assure an adequate approach both preoperatively and in possible serious postoperative complications, as well the common perioperative complications, which tend to be cardiovascular, pulmonary and of the upper airway, especially in patients with a higher degree of thyroid dysfunction (moderate, severe). Additionally, based on this non-systematic review of the literature, we propose a management algorithm for this patient population.

El manejo preoperatorio de los pacientes con hipotiroidismo marca la diferencia en los desenlaces clínicos del posoperatorio, sin embargo, se ha encontrado que hay falta de evidencia en cuanto a recomendaciones en el manejo en este escenario, por lo que realizamos una búsqueda de la literatura en inglés y español de los años 2000 al 2020 en las bases de datos PubMed, ProQuest, Scopus y Embase sobre fisiología, fisiopatología y recomendaciones actuales del manejo preoperatorio en estos pacientes. Es de gran importancia conocer los cambios fisiológicos e implicaciones en el manejo anestésico de estos pacientes, para un adecuado abordaje tanto en el preoperatorio como en posibles complicaciones graves en el posoperatorio, así como las complicaciones más frecuentes, los cuales son cardiovasculares, pulmonares y de la vía aérea superior, esto en pacientes con mayor grado de disfunción tiroidea (moderado, severo). Adicionalmente, basado en esta revisión no sistemática de la literatura, proponemos un algoritmo de manejo en esta población de pacientes.
