Introduction:Postoperative chronic pain (PCP) is defined as a discomfort that lasts more than expected or beyond 3 months after surgery. The recognition and study of this clinical entity has been gaining interest in the past few years. One of the main reasons is the great impact it can have on the quality of life of patients who suffer from it. Objective: To describe the prevalence, risk factor and impact of PCP on patients subjected to different surgical procedures. Materials and Methods: Search on MED-LINE/Pubmed, using the following terms: "chronic postsurgical pain", "chronic post operative pain", "chronic post operative pain", "chronic post surgical pain". Publications were then sieved using their title and abstract. Results: Fifty-seven articles were analyzed. Ten to fifty percent of patients were reported as suffering PCP, with up to 10% incidence of severe pain. The main risk factors identified were the use of analgesics, pre-operative pain and type of surgery. Orthopedic surgery was highly associated with moderate to severe PCP within the first year. Twenty-one percent of patients referred PCP affected their quality of life and sleep; ability to carry out physical activity and return to work. Conclusion: The first approach to PCP is getting to know its impact and epidemiology. Surgical treatments can cause PCP, which will affect patient recovery and increase costs. Recognizing those patients at risk and establishing preventive management protocols could improve the quality of life of postsurgical patients.
Introducción: Un adecuado manejo del sangrado debe incluir la correcta valoración y eventual reposición de fibrinógeno. Las fuentes tradicionales de este elemento hemostático incluyen el plasma fresco congelado y los crioprecipitados. Los concentrados liofilizados de fibrinógeno humano (CFH) son una alternativa terapéutica novedosa en el mercado chileno. Este estudio describe el curso clínico de los primeros pacientes en nuestra institución requirentes de CFH, dentro de un algoritmo de reposición hemostática por metas.Método: Serie de pacientes con hipofibrinogenemia secundaria a sangrado perioperatorio severo, en los que se utilizó CFH como método de reposición de fibrinógeno. Se utilizó tromboelastometría para definir dosis. Se registraron variables demográficas, operatorias, complicaciones y seguimiento hasta los 3 meses.Resultados: Se utilizaron CFH en 18 pacientes. La mediana de edad fue 40,7(56,5 – 63) años y dos tercios de los pacientes fueron de sexo masculino. Fallecieron 5 pacientes de la serie. Todos los pacientes requirieron manejo postoperatorio en una unidad de cuidados intensivos. Ocho pacientes fueron sometidos a cirugía cardiaca. El uso de hemocomponentes y concentrados liofilizados fue heterogéneo, pero en todos los casos su uso fue determinado por tromboelastometría. Ningún paciente fue re-intervenido a causa de sangrado postoperatorio.Conclusión: El uso de concentrados de fibrinógeno humano dentro de un algoritmo de manejo de sangrado guiado por tromboelastometría, es un recurso hemostático factible en la realidad nacional. El impacto clínico de esta intervención requiere una subsiguiente evaluación basada en la evidencia.
