Hipertensão intra-abdominal e síndrome compartimental abdominal: repercussões e tratamento clínico no paciente crítico / Intra-abdominal hypertension and abdominal compartment syndrome: repercussions and clinical treatment in critically ill patients

A hipertensão intra-abdominal e a síndrome compartimental abdominal foram durante muitas décadas mal compreendidas e dissociadas de suas repercussões clínicas. Trata-se de um distúrbio que pode levar à disfunção de múltiplos órgãos devido ao desequilíbrio circulatório desencadeado pelo aumento de pressão no compartimento abdominal. As manifestações envolvem os sistemas cardiovascular, respiratório, renal, nervoso e gastrintestinal e estão largamente relacionadas com o fator de morbimortalidade no paciente crítico. A despeito da importância clínica, a hipertensão intra-abdominal e à síndrome compartimental abdominal ainda são temas pouco dominados pelos médicos, e fazem-se necessários o reconhecimento precoce e o estabelecimento de estratégias clínicas objetivas no contexto de uma síndrome com desfecho tão desfavorável. Portanto, foi realizada uma revisão da literatura não sistematizada com objetivo de compreender os principais pontos sobre definições, prevalência, fatores de risco, fisiopatologia, diagnóstico e tratamento acerca da hipertensão intra-abdominal e a síndrome compartimental abdominal.

Intra-abdominal hypertension and abdominal compartment syndrome have been, for many decades, poorly understood and dissociated from their clinical repercussions. It is a disorder that can lead to organ dysfunction due to circulatory impairment triggered by increased pressure in the abdominal compartment. The manifestations involve cardiovascular, respiratory, renal, nervous, and gastrointestinal systems, and are widely associated with significant morbidity and mortality in critically ill patients. Despite their clinical importance, intra-abdominal hypertension and abdominal compartment syndrome are still not sufficiently known by physicians and, early recognition and the establishment of objective clinical strategies for managing these highly morbid syndromes are required. Therefore, a non-systematized review was carried out to understand the main points about definitions, prevalence, risk factors, pathophysiology, diagnosis, and treatment of intra-abdominal hypertension and abdominal compartment syndrome.

Caracterización del síndrome compartimental abdominal en pacientes críticos / Characterization of abdominal compartment syndrome in critical patients

RESUMEN Introducción: el síndrome compartimental abdominal es una entidad clínica sistémica desencadenada por incremento en la presión intraabdominal, caracterizada clínicamente por distensión abdominal y alteraciones de las funciones respiratoria, cardiovascular, neurológica y renal. Objetivo: caracterizar el comportamiento del síndrome compartimental abdominal en los pacientes críticos que ingresaron en la unidad de cuidados intensivos del Hospital Provincial "José Ramón López Tabrane". Materiales y método: se realizó un estudio prospectivo, descriptivo, y longitudinal que tuvo como universo los pacientes adultos con factores de riesgo conocidos para síndrome compartimental abdominal, tratados entre enero de 2014 a diciembre de 2015. Se le realizó medición sistemática de la presión intraabdominal transvesical y fueron sometidos a descompresión quirúrgica en caso de hipertensión intraabdominal grados III y IV. Resultados: los valores de presión intraabdominal sostenidamente elevados, son directamente proporcionales al desarrollo del síndrome compartimental abdominal y trae aparejado disfunciones en los diferentes sistemas de órganos; en estos casos apareció complicaciones, las cuales se presentaron combinadas para todos los pacientes, y fueron mayoritarias para el grupo con presión intraabdominal grado IV. La mortalidad se comportó en un número bastante elevado lo cual estuvo relacionado con los niveles de presión intraabdominal, así como la posibilidad de que fueran reintervenidos quirúrgicamente estos pacientes. Conclusiones: se debe protocolizar en todo paciente con sospecha de desarrollar un síndrome compartimental abdominal la medición periódica de la presión intraabdominal (AU).

SUMMARY Introduction: the abdominal compartment syndrome is a systemic clinical entity triggered by an increase of the intra abdominal pressure, clinically characterized by abdominal distension and the alteration of the renal, neurological, cardiovascular and respiratory functions. Objective: to characterize the behavior of the abdominal compartment syndrome in critical patients from the intensive care unit of the provincial hospital "Jose Ramon Lopez Tabrane". Materials and methods: a longitudinal, descriptive and prospective study was carried out in a universe of adult patients with risk factors known as abdominal compartment syndrome, treated in the period of time from January 2014 to December 2015. Their transvesical intraabdominal pressure was systematically measured and they underwent surgical decompression in cases of intraabdominal hypertension grades iii and iv. Results: the values of intraabdominal pressure steadily increased are directly proportional to the development of the abdominal compartment syndrome and entails dysfunctions in the different systems of organs; in these cases complications were found, that were combined for all patients and mainly in the group with intraabdominal pressure grade iv. Mortality was present in a certainly increased group, and was related to the levels of intraabdominal pressure, and also to the possibility these patients undergoing surgical treatments again. Conclusions: it should be standardized the periodical measure of the intraabdominal pressure in any patient suspected of developing an abdominal compartment syndrome (AU).

Resumen El presente artículo tiene como finalidad realizar una revisión bibliográfica acerca del síndrome compartimental abdominal en el paciente pediátrico, para actualizar a la población médica general respecto al tema en cuestión; debido a que no hay actualmente estudios de peso estadístico en cuanto a la patología; además, no hay estudios recientes a nivel nacional. El síndrome compartimental abdominal es una condición clínica seria, que presenta una mortalidad elevada sobre todo en la población pediátrica. El desconocimiento de la patología es el principal factor determinante en la mortalidad; ya que, es fundamental la sospecha médica oportuna para inicio de medidas terapéuticas evitando disfunción orgánica y muerte. Por lo tanto, en el siguiente trabajo, se desarrollarán los puntos fundamentales sobre su incidencia, presentación clínica, factores de riesgo, fisiopatología, abordaje diagnóstico y los distintos abordajes terapéuticos, tanto médicos como quirúrgicos; así como, complicaciones y pronósticos. Sin olvidar el punto clave que es conocer la técnica para la medición de la presión intraabdominal, lo que posibilita la detección precoz de complicaciones y consecuentemente, un accionar terapéutico oportuno.

Abstract The purpose of this article is to carry out a bibliographic review about abdominal compartment syndrome in the pediatric patient, to update the medical population about this topic, because currently there are no studies with enough statistical weight about this pathology. Furthermore, there aren´t recent studies at the national level. Abdominal compartment syndrome is a serious clinical condition that has an elevated mortality rate, especially in the pediatric population. The ignorance of the pathology it is the main determining factor in mortality because it is fundamentally the timely medical suspicion to start therapeutic measures avoiding organ dysfunction and death. Therefore, in the following work, the fundamental points will be developed about its incidence, clinical presentation, risk factors, pathophysiology, diagnosis, approach and the different therapeutic approaches medical and surgical as well as complications and prognosis. Without forgetting the key point which is knowing the technique for the measurement of intra abdominal pressure, which will allow the early detection of complications and consequently, a timely therapeutic action.

Não mensurou a pressão intra-abdominal 81,6% dos entrevistados, por não haver protocolo definido pelo serviço. Setenta e nove por cento dos entrevistados afirmou não conhecer as definições do consenso do World Society of the Abdominal Compartment Syndrome (WSACS). Conclusão: metade dos médicos foi capaz de classificar hipertensão intra-abdominal e indicar o início de um quadro de síndrome compartimental abdominal corretamente.

ABSTRACT Objective: to assess the physicians' knowledge regarding intra-abdominal hypertension and abdominal compartment syndrome and to compare it with the established literature. Methods: we conducted a descriptive, observational, cross-sectional, quantitative study. We interviewed 38 physicians through a self-administered questionnaire composed of objective questions. We carried out the study in a tertiary reference university hospital, located in Curitiba, Paraná. Results: the mean age of the participants was 28 years, 60.5% were female and the mean time of medical experience was 3.5 years. Regarding the knowledge on the subject, 57.9% considered that abdominal compartment syndrome starts with intra-abdominal grade III hypertension, 50% considered abdominal perfusion pressure the most reliable method to determine intra-abdominal hypertension, 89.4% considered the intravesical measuring technique as the most used, 71.1% considered oliguria to be the early sign of abdominal compartment syndrome. Of the interviewees, 81.6% did not measure intra-abdominal pressure because there was no protocol defined by the service. Seventy-nine percent of respondents said they did not know the definitions of the consensus of the World Society of the Abdominal Compartment Syndrome (WSACS). Conclusion: half of the physicians were able to classify intra-abdominal hypertension and indicate the onset of abdominal compartment syndrome correctly.

Intra-abdominal pressure: an integrative review / Pressão intra-abdominal: revisão integrativa

ABSTRACT There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 2012. Twenty articles were identified, in that, 12 literature reviews, 4 descriptive and exploratory studies, 2 expert opinions, one prospective cohort study and one was an experience report. The vesical intra-abdominal pressure measurement was considered gold standard. There are variations in the technique however, but some common points were identified: complete supine position, in absence of abdominal contracture, in the end of expiration and expressed in mmHg. Most research results indicate keeping the transducer zeroed at the level of the mid-axillary line at the iliac crest level, and instill 25mL of sterile saline. Strong evidence must be developed.

RESUMO Em pacientes críticos com quadros abdominais agudos a esclarecer é crescente a solicitação da aferição da pressão intra-abdominal. Sintetizar resultados de pesquisas sobre a mensuração da pressão intra-abdominal pela via vesical e analisar o nível de evidência foram os objetivos desta revisão integrativa da literatura, realizada nas bases LILACS, MEDLINE e PubMed, no período de 2005 a julho de 2012. Identificaram-se 20 artigos, sendo 12 revisões de literatura, 4 estudos exploratório-descritivos, 2 opiniões de especialistas, 1 estudo de coorte prospectivo e 1 relato de experiência. O método vesical para mensuração da pressão intra-abdominal foi considerado padrão-ouro. Existem variações na técnica, entretanto pontos em comum foram identificados: posição supina completa, na ausência de contratura abdominal, ao final da expiração e expressa em mmHg. A maioria indica posicionar o ponto zero do transdutor na linha axilar média, ao nível da crista ilíaca e instilar 25ml de solução salina estéril. Evidências fortes precisam ser desenvolvidas.

Value of abdominal pressure measurement in neonatal abdominal surgical emergencies

To assess the predictive and prognostic value of abdominal pressure measurement in neonatal abdominal surgical emergencies. Case series. Zagazig University Hospitals [Egypt] and King Fahd Hospital, Hofuf [KSA]. Seventy nine neonatal abdominal surgical emergencies admitted and managed over a four-year period [Jan 2005 to Jan 2009] Measurement of abdominal pressure through management period. Abdominal pressure was classified into pressure at presentation [T1], preoperative [T2], and postoperative pressure [T3]. The levels of pressure were classified into [pA] below 12 mmHg, [pB] 12-20 mmHg, and [pC] more than 20 mmHg. Seventy-nine neonates were included. There was significant high abdominal pressure in jejunoileal atresia, necrotizing enterocolitis [NEC], and duodenal obstruction. In pyloric stenosis, there was no significant abdominal hypertension all over the management period. Temporary elevations occurred preoperatively [T1] in meconium ileus, cecal perforation, and jejunal stenosis. Significant association was found between [T1] and mortality, postoperative blood transfusion, need for mechanical ventilation, and sepsis. No correlation was found with blood need or sepsis. Postoperative complications had significant association with elevated postoperative abdominal pressure [T3]. Intra-abdominal pressure [IAP] can be of importance in monitoring changes which accompany neonatal surgical emergencies. It can be of predictive and prognostic value in neonatal surgical emergencies. However, more controlled studies are needed to confirm this conclusion

Medición de la presión intraabdominal para la vigilancia posoperatoria de la cirugía abdominal / Measurement of intraabdominal pressure for the postoperative surveillance of abdominal surgery

Se realizó un estudio de serie de casos de 286 pacientes laparotomizados que ingresaron en la Unidad de Cuidados Intensivos del Hospital General Vladimir Ilich Lenin (Holguín), entre el 4 de marzo de 1999 y el 29 de enero del 2003. El objetivo fue describir el comportamiento de la edad, sexo, diagnóstico al ingreso, frecuencia de complicaciones intraabdominales posoperatorias y el resultado al egreso de estos pacientes. Según el APACHE II, la escala pronóstica de gravedad fue de 13,1. Las principales causas del ingreso fueron peritonitis (34,9 por ciento) y politraumatismos (19,52 por ciento). Encontramos complicaciones posoperatorias en el 32,5 por ciento de los pacientes. La presión intraabdominal en los pacientes complicados fue de 14,94 ± 4,88 cm H2O, mientras que en los pacientes que no tuvieron complicaciones fue de 11,67 ± 4,63 cm H2O (F = 31,4948; p < 0,05). Hubo 94 fallecidos (32,8 por ciento) y su presión intraabdominal fue de 14,22 ± 5,18 cm H2O. En cambio, en los sobrevivientes la presión fue de 12,07 ± 4,74 cm H2O (F = 12,2824; p < 0,05). Los pacientes con complicaciones posoperatorias y con resultados desfavorables al egreso de la unidad de cuidados intensivos tienen una presión intraabdominal más alta que los que evolucionan favorablemente(AU)

A case series study that included 286 laparotomized patients that were admitted at the ICU of Vladimir Ilich Lenin General Hospital, in Holguin, between March 4, 1999 and January 29, 2003, was conducted. The objective was to describe the behavior of age, sex, diagnosis on admission, frequency of intraabdominal postoperative complications, and the result attained in these patients on discharge. According to APACHE II, the prognostic scale of severity was 13.1. The main cause of hospitalization were peritonitis (34.9 per cent) and polytraumas (19.52 per cent). Postoperative complications were found in 32.5 per cent of the patients. Intraabdominal pressure in the complicated patients was 14.94 ± 4.88 cm H2O; whereas, in those patients without complications it was11.67 ± 4.63 cm H2O (F = 31.4948; p < 0.05). There were 94 deaths (32.8 per cent) and their intrabdominal pressure was 14.22 ± 5.18 cm H2O. However, the survivors’ pressure was 12.07 ± 4.74 cm H2O (F = 12.2824; p < 0.05). The patients with postoperative complications and unfavorable results on discharge from the ICU had a higher intrabdominal pressure than those with a satisfactory evolution(AU)
