Clinical practice guidelines for evidence-based management of sedoanalgesia in critically ill adult patients.

INTRODUCTION: Optimal management of sedation, analgesia and delirium offers comfort and security for the critical care patient, allows support measures to be applied more easily and enables an integral approach of medical care, at the same time that lowers the incidence of complications, wich translates in better patient outcomes. OBJECTIVE: To update the Guía de práctica clínica basada en la evidencia para el manejo de la sedoanalgesia en el paciente adulto críticamente enfermo published in Medicina Intensiva in 2007, and give recommendations for the management of sedation, analgesia, and delirium. METHODOLOGY: A group of 21 intensivists from 9 countries of the Federación Panamericana e Ibérica de Sociedades de Medicina Crítica y Terapia Intensiva, 3 of them also specialists in clinical epidemiology and methodology, gathered for the development of guidelines. Assessment of evidence quality and recommendations were made based on the Grading of Recommendations Assessment, Development and Evaluation system. Strength of recommendations was classified as 1=strong, or 2=weak, and quality of evidence as A=high, B=moderate, or C=low. Two authors searched the following databases: MEDLINE through PUBMED, The Cochrane Library and Literatura Latinoamericana y del Caribe en Ciencias de la Salud and retrieved pertinent information. Members assigned to the 11 sections of the guidelines, based on the literature review, formulated the recommendations, that were discussed in plenary sessions. Only those recommendations that achieved more than 80% of consensus were approved for the final document. The Colombian Association of Critical Medicine and Intensive Care (AMCI) supported the elaboration of this guidelines. RESULTS: Four hundred sixty-seven articles were included for review. An increase in number and quality of publications was observed. This allowed to generate 64 strong recommendations with high and moderate quality of evidence in contrast to the 28 recommendations of the previous edition. CONCLUSIONS: This Guidelines contains recommendations and suggestions based on the best evidence available for the management of sedation, analgesia and delirium of the critically ill patient, including a bundle of strategies that serves this purpose. We highlight the assessment of pain and agitation/sedation through validated scales, the use of opioids initially to apropiate analgesic control, associated with multimodal strategies in order to reduce opioide consumption; to promote the lowest level of sedation necessary avoiding over-sedation. Also, in case of the need of sedatives, choose the most appropiate for the patient needs, avoiding the use of benzodiazepines and identify risk factors for delirium, in order to prevent its occurrence, diagnose delirium and treat it with the most suitable pharmacological agent, whether it is haloperidol, atypical antipsychotics or dexmedetomidine, once again, avoiding the use of benzodiazepines and decreasing the use of opioids.

The future of intensive care medicine / El futuro de la medicina intensiva

Intensive care medical training, whether as a primary specialty or as secondary add-on training, should include key competences to ensure a uniform standard of care, and the number of intensive care physicians needs to increase to keep pace with the growing and anticipated need. The organisation of intensive care in multiple specialty or central units is heterogeneous and evolving, but appropriate early treatment and access to a trained intensivist should be assured at all times, and intensivists should play a pivotal role in ensuring communication and high-quality care across hospital departments. Structures now exist to support clinical research in intensive care medicine, which should become part of routine patient management. However, more translational research is urgently needed to identify areas that show clinical promise and to apply research principles to the real-life clinical setting. Likewise, electronic networks can be used to share expertise and support research. Individuals, physicians and policy makers need to allow for individual choices and priorities in the management of critically ill patients while remaining within the limits of economic reality. Professional scientific societies play a pivotal role in supporting the establishment of a defined minimum level of intensive health care and in ensuring standardised levels of training and patient care by promoting interaction between physicians and policy makers. The perception of intensive care medicine among the general public could be improved by concerted efforts to increase awareness of the services provided and of the successes achieved (AU)

La formación en medicina intensiva, ya sea como especialidad primaria o a partir de una troncalidad común para después convertirse en supra-especialidad, debería incluir competencias clave que garanticen un cuidado estándar y homogéneo del paciente crítico, así como proveer al sistema sanitario del número de especialistas en medicina intensiva (intensivistas) de forma ajustada y anticipada al ritmo de crecimiento de la necesidad asistencial. La organización de los cuidados intensivos desde la visión de las distintas especialidades o en unidades centralizadas y jerarquizadas, es heterogénea y está en constante evolución. No obstante el acceso y tratamiento precoz del enfermo crítico por parte de un intensivista, debería estar siempre garantizado, no únicamente en los servicios de medicina intensiva, sino en todos los departamentos de un hospital, actuando el intensivista como elemento central en la comunicación y coordinación entre los diferentes servicios y especialistas, a fin de lograr la más alta calidad y eficacia en la asistencia. La investigación clínica en medicina intensiva está sustentada por la excelencia de conocimiento de sus profesionales, pero son necesarias estructuras de apoyo: la integración de la investigación e innovación en la rutina diaria y un incremento de la investigación traslacional, a fin de identificar áreas que muestren elementos potenciales de avance en el aspecto clínico y la aplicación de los principios de la investigación básica y fisiológica en el entorno de la medicina intensiva. Las tecnologías de la comunicación y la información ofrecen un marco idóneo para compartir y poner en común el conocimiento y apoyar (..) (AU)

Uneventful pregnancy and delivery in a patient with idiopathic pulmonary hypertension: a case report

Idiopathic pulmonary hypertension is a rare disease characterized by sustained elevation of the pulmonary artery pressure and pulmonary vascular resistance, normal pulmonary artery wedge pressure, in the absence of a known cause. Prior reports suggest a very high maternal mortality in patients with idiopathic pulmonary hypertension undergoing pregnancy, and for that the recommendation has been avoidance of pregnancy (or termination if the patient is already pregnant). On the other hand, there have been multiple reports of patients with idiopathic pulmonary hypertension sustaining pregnancy and labor without major complications. This case report illustrates the course of pregnancy and labor in a patient diagnosed with idiopathic pulmonary hypertension. At age 24, the patient started with symptoms of shortness of breath and chest pain, and upon evaluation she was found with moderately severe idiopathic pulmonary hypertension. One year and 8 months later the patient becomes pregnant, and begins follow up with gynecology and cardiology. During this time the patient was asymptomatic, and did not have any clinical evidence of pulmonary hypertension. The risks of pregnancy were discussed with the patient, and she decided to continue pregnancy. She had an uneventful pregnancy, complicated only by preterm labor at 34 weeks and 5 days of gestation. She had spontaneous labor and delivered vaginally a healthy baby boy, weighting 4 pounds and 12 ounces. No invasive monitoring was used. The mother and the baby were discharged home 48 hours postpartum. Seven months later the patient returned for evaluation, presenting evidence of severe pulmonary hypertension. She has been followed up ever since by a cardiologist and currently is stable but symptomatic. This report adds to the amount of evidence that suggests that pregnancy and labor in a patient with idiopathic pulmonary hypertension may have a better outcome than previously reported. The decision of undertaking and/or continuing pregnancy in a patient with idiopathic pulmonary hypertension relies ultimately on the patient's choice, but should be done on an individual basis after careful evaluation of the risks. Finally, the need of close follow up with a multidisciplinary team is mandatory in the patient with idiopathic pulmonary hypertension that wishes to undergo pregnancy.

Primary pulmonary hypertension and pregnancy

Primary pulmonary hypertension (PPH) is a disorder intrinsic to the pulmonary vascular bed characterized by sustained elevation in pulmonary artery pressure and pulmonary vascular resistance with normal pulmonary artery wedge pressure, in the absence of a known cause. Cardiovascular disorders are the most common cause of morbidity and mortality in pregnant women. Risk is so great with some cardiovascular abnor-malities that recommendation of avoidance or interruption of pregnancy is supportable, one of these conditions is pulmonary hypertension. In this article two patients with primary pulmonary hypertension who sustained two pregnancies each are described. Both patients had uneventful pregnancies and deliveries, with all neonates surviving. When evaluating primary pulmonary hypertension and pregnancy, early studies reported a maternal mortality rate as high as 50%. More recent studies report a maternal mortality of 30%. In this article, cases of primary pulmonary hypertension undergoing pregnancy from 1978 to 2005 were reviewed, revealing a 22% maternal mortality for the total number of pregnancies. Despite advances in treatment, primary pulmonary hypertension continues to carry considerable maternal morbidity and mortality, and prevention of pregnancy is still the main recommendation. Early diagnosis and treatment is critical and a multi-disciplinary approach is required when dealing with a patient with PPH who desires to continue pregnancy.

Bullous pemphigoid: course of the disease. A study of 25 patients

Different studies on the course of bullous pemphigoid have suggested that there may be significant variations in the survival of these patients based on their ethnicity or region of origin. Because of the lack of studies on patients with bullous pemphigoid in the Caribbean, specifically in Puerto Rico, a retrospective analysis about the outcome of patients with this disease in the region was performed. Twenty-five (25) patients were included in this study. The patients were diagnosed as bullous pemphigoid by clinical, histopathologic and immunopathologic assessment. Medical records were reviewed and those patients that were alive were contacted and examined on a follow up visit. Nine were men and sixteen were women; the age at the time of the diagnosis ranged from 54 to 90 year-old (mean 72); 13 were alive after at least 5 years of follow-up and 12 had died. The age at the moment of death ranged from 67 to 95 year-old (mean 83). Of those patients living, 85 were in remission, while 15 had active disease. In general, patients had a disease of mild severity, but, still, 68 of them received systemic corticosteroid therapy. Five of patients had to be admitted due to disease; two of them died while at the hospital. This data suggests that bullous pemphigoid in Puerto Ricans is a disease with a relatively benign course, but which can be fatal in the elderly, especially, if it requires admission to the hospital and the patient receives high doses of systemic corticosteroids

Distribution of Leu-7 antigen (HNK-1) in thyroid tumors: its usefulness as a diagnostic marker for follicular and papillary carcinomas.

The reactivity of the anti-Leu-7 monoclonal antibody was tested in 39 neoplastic and nonneoplastic thyroid tissue specimens. These included eight colloid goiters, 14 follicular adenomas, nine papillary carcinomas, five follicular carcinomas, two medullary carcinomas, and one metastatic follicular carcinoma in bone. We observed strong cytoplasmic and/or cell membrane positivity in all follicular and papillary carcinomas, in both primary and metastatic tumors. However, the medullary thyroid carcinomas tested were negative. We also observed weak and only occasional staining with anti-Leu-7 antibody in colloid goiter and follicular adenomas. The staining in the benign thyroid lesions was usually focal, less than 10% of the cells; however, in cases of follicular and papillary carcinomas, both in primary and metastatic tumors, the staining was diffuse and strong. Some of the colloid material in colloid goiters and follicular adenomas showed faint homogenous staining with anti-Leu-7 antibody. Our findings suggest that anti-Leu-7 monoclonal antibody is a marker that may facilitate the differentiation between benign and malignant thyroid lesions, with the exception of medullary carcinoma. In addition, caution should be taken when using this antibody to diagnose metastatic lesions, as other metastatic carcinomas have also been reported to be positive. This antibody should be used in conjunction with a panel of antisera to complement a morphologic diagnosis.
