ABSTRACT

BACKGROUND: Thromboprophylaxis in surgical patients requires specific measures to implement regional anesthesia techniques. In this regard the current clinical practice guidelines of anesthesiology summarizes the recommendations of the review of current evidence. OBJECTIVE: We must recognize the general guidelines for thromboprophylaxis and impact modifiers of coagulation for the Surgical Team to implement the actions for each specific patient. DISCUSSION: The most feared event by anesthesiologists is the spinal hematoma, but given its rarity there is a prospective randomized study, nor is there currently a laboratory model. Therefore the consensus established clinical practice recommendations for making a decision to anesthesia / analgesia epidural or spinal or peripheral nerve and the time of catheter removal in a patient receiving coagulation modifiers should be based on a individual analysis, weighing the small but definite risk of neuraxial hematoma with the benefits of regional anesthesia for a specific patient. CONCLUSION: the coagulation status should be evaluated and optimized at the time of placement of a needle anesthesia or continue either epidural, spinal or peripheral nerve blockade to continue prophylaxis as a priority without minimizing the risk of serious complications such as spinal bleeding.

ABSTRACT

The diagnosis of deep vein thrombosis (DVT) is unusual in patients with sickle cell disease (SCD). Despite the incidence of cerebral thrombosis in SCD patients due to vasooclusion, thrombotic manifestations in peripheral vessels are rare. Patients with homozygous SCD present a variety of renal abnormalities as a result of sickle crisis. In this group of patients, kidney transplantation has been performed in the renal endstage patients; with graft survival rates similar to that of the general transplant population at 1 year. However, patients with SCD experience an augmentation in the frequency of painful crises in the first year after transplantation, which has been attributed to concurrent elevations in hematocrit and plasma viscosity. Despite etiology, renal transplant patients are at increased risk for the development of thromboembolic events such as deep vein thrombosis and renovascular thrombosis after allograft procedure. These events can be due to a prothrombotic state generated by the use of immunosuppressive agents. Although other factors such as acquired or inherited disorders of the clotting system may increase the risk of thrombosis. Here, we report a case of a renal transplant patient with sickle cell disease who presented recurrent episodes of DVT and increase painful sickle episodes after kidney transplantation.

ABSTRACT

BACKGROUND: Treatment of deep-vein thrombosis (DVT) with a once-daily regimen of enoxaparin, rather than a continuous infusion of unfractionated heparin (UFH) is more convenient and allows for home care in some patients. This study was designed to compare the efficacy and safety of these two regimens for the treatment of patients with proximal lower limb DVT. METHODS: 201 patients with proximal lower limb DVT from 13 centers in Brazil were randomized in an open manner to receive either enoxaparin [1.5 mg/kg subcutaneous (s.c.) OD] or intravenous (i.v.) UFH (adjusted to aPTT 1.5-2.5 times control) for 5-10 days. All patients also received warfarin (INR 2-3) for at least 3 months. The primary efficacy endpoint was recurrent DVT (confirmed by venography or ultrasonography), and safety endpoints included bleeding and serious adverse events. The rate of pulmonary embolism (PE) was also collected. Hospitalization was at the physician's discretion. RESULTS: Baseline patient characteristics were comparable between groups. The duration of hospital stay was significantly shorter with enoxaparin than with UFH (3 versus 7 days). In addition, 36% of patients receiving enoxaparin did not need to be hospitalized, whereas all of the patients receiving UFH were hospitalized. The treatment duration was slightly longer with enoxaparin (8 versus 7 days). There was a nonsignificant trend toward a reduction in the rate of recurrent DVT with enoxaparin versus UFH, and similar safety. CONCLUSIONS: A once-daily regimen of enoxaparin 1.5 mg/kg subcutaneous is at least as effective and safe as conventional treatment with a continuous intravenous infusion of UFH. However, the once daily enoxaparin regimen is easier to administer (subcutaneous versus intravenous), does not require aPTT monitoring, and leads to both a reduced number of hospital admissions and an average 4-day-shorter hospital stay.

ABSTRACT

La nutrición parental periférica (NPP) es una técnica por medio de la cual soluciones nutricionales son infundidas a travéz de venas periféricas, condicionando una asistencia nutricional completa o parcial, evitando la colocación de un catéter venoso central. Esto último es su mayor ventaja. Sin embargo, la nutrición parental periférica tiene ciertas limitaciones y ostenta algunas complicaciones ocasionalmente, entre las cuales la mas importante es la tromboflebitis. En esta revisión se discuten y analizan los factores responsables de estas tromboflebitis iatrogénicas y las medidas y recomendaciones para prevenirlas

ABSTRACT

En el Hospital Central Militar se han realizado cuatro estudios previos sobre prevención de la TVP con diferentes medicamentos, encontrando que hasta la fecha el que mejores resultados y menores complicaciones ha dado es la enoxaparina. Se realizó un estudio prospectivo, longitudinal y abierto de 120 pacientes adultos que ingresaron por el servicio de urgencias en el periodo comprendido del 1o. de mayo de 1995 al 31 de mayo de 1997, con el diagnóstico de fracturas mayores de las extremidades inferiores y quienes cumplieron con los criterios de inclusión. Estos pacientes fueron manejados con enoxaparina a dosis de 40 mg subcutáneos al momento de su ingreso (antes de 6 horas) y continuada con 40 mg SC diarios hasta 10 días después de las intervenciones predominaron los pacientes ancianos con fracturas de cadera, fracturas de fémur en politraumatizados y fracturas de tibia y peroné. Completaron el estudio 107 pacientes. El porcentaje de complicaciones tromboembólicas fue de 8.4 por ciento (9 pacientes); de éstos un paciente presentó un evento vascular cerebral trombótico el cual falleció a los 14 días del postoperatorio y los otros 8 presentaron trombosis venosa profunda. Se presentó principalmente en los pacientes ancianos con fractura de cadera. No hubo complicaciones hemorrágicas locales pre, trans o posoperatorias. Dos pacientes presentaron hemorragia gastrointestinal alta asociada a AINE, fracturas múltiples y estancia prolongada. La complicación más frecuente fue la presencia de pequeñas equimosis en el sitio de aplicación en 70 pacientes. La hemorragia transoperatoria fue la habitual para pacientes sometidos a cirugía ortopédica mayor. Un paciente cardiópata falleció en el transoperatorio por bloqueo AV completo irreversible. En cuatro pacientes hubo infección de la herida. No hubo reacciones alérgicas ni signos de toxicidad en ningún caso. Con esto pudimos concluir que la profilaxis de las complicaciones tromboembolicas con heparinas de bajo peso molecular es eficaz y segura aun en los pacientes con fracturas mayores de las extremidades inferiores, disminuyendo considerablemente el riesgo de presentación de estas complicaciones, que pueden dejar secuelas e incluso causar la muerte de estos pacientes. La tolerancia es excelente y las complicaciones son mínimas. Se debe vigilar la estricta aplicación del protocolo de manejo desde el servicio de urgencias para continuar reduciendo la tasa de presentación de estas complicaciones

ABSTRACT

Se realizó un estudio en el Departamento de Ortopedia del Hospital Central Militar de septiembre de 1989 a diciembre de 1994, para determinar la frecuencia de trombosis venenosa profunda (TVP), como complicación de la cirugía de miembros pélvicos y para la búsqueda de un esquema profiláctico farmacológico. La primera fase del estudio se realizó en pacientes a los que se les practicó cirugía mayor de cadera y rodilla, se encontró una incidencia del problema de 51 por ciento, sin esquema profiláctico; en la segunda fase se utilizó una combinación de heparina estándar y dehidroergotamina y se encontró una disminución de la incidencia de la trombosis hasta el 38 por ciento. En la tercera fase se uso una heparina de bajo peso molecular (enoxaparina), se observaron menos efectos adversos y disminución de la trombosis hasta 13 por ciento. En la cuarta fase se uso otra heparina de bajo peso muscular, la tedegliparina CY 216, (fraxiparina), la incidencia de la trombosis profunda venenosa fue del 15.01 por ciento. Se concluye que la cirugía mayor de cadera y rodilla se complica frecuentemente con TVP por lo que amerita una minuciosa profilaxis, el esquema heparina estándar/dehidroergotomina brinda protección parcial, las heparinas de bajo peso muscular dan mayor cobertura y de las dos usadas se obtuvo mejor resultado con enoxaparina; y finalmente, que en el caso de la TVP tanto la clínica como el Doppler tienen importantes limitaciones

ABSTRACT

For preventing thromboembolic events, the concurrent use of oral anticoagulant and antiplatelet drugs has been proposed. In prosthetic heart valves the use of moderate intensity anticoagulants [International Normalized Ratio (INR) 2-3] plus aspirin (100 mg/day) decreases the amount and severity of embolic episodes. The possibility that the same regimen could provide benefit in the prevention of thrombotic events in other arterial diseases is also indicated by the ATACS trial in unstable angina. The ongoing studies in ischemic heart diseases will also give the answer to this possibility.

ABSTRACT

OBJECTIVE: To compare the incidence of and factors associated with vascular thrombosis after placement of heparin-bonded and standard femoral venous catheters. DESIGN: Prospective, masked, clinical study. SETTING: Multidisciplinary, tertiary, pediatric intensive care unit. PATIENTS: Consecutive cases (n = 50) of critically ill children admitted to a pediatric intensive care unit in whom either a heparin-bonded (n = 25) or a standard (n = 25) femoral venous catheter was placed. MEASUREMENTS AND MAIN RESULTS: Patients were examined by ultrasonography within 3 days of catheter insertion, weekly while the catheter was in place, and after catheter removal for evidence of vascular thrombosis. Data were collected prospectively regarding clinical evidence of catheter thrombosis, infusate composition, and positive blood culture results. Of 50 patients, 13 (26%) had thrombotic complications, 11 (44%) of the 25 patients in the standard-catheter group, in comparison with 2 (8%) of the 25 patients in the heparin-bonded catheter group (p = 0.004). In addition, there was a significantly higher incidence of positive blood culture results among patients in the standard-catheter group (24% vs 0%; p = 0.009). Positive catheter blood culture results were obtained in 38% of patients with thrombosis versus 3% without thrombosis (p = 0.001). Clinical evidence of thrombosis was found in 69% of patients with, versus 27% of patients without, ultrasound-proved thrombosis (p = 0.007). CONCLUSION: Heparin bonding of catheters is associated with significantly fewer thrombotic complications. A reduced incidence of positive catheter-related blood culture results may be associated with the absence of thrombosis.
