Résumé
Introducción: Más de dos millones de personas en el mundo reciben tratamiento sustitutivo renal; la infección sanguínea representa una amenaza significativa, siendo la segunda causa de muerte en estos pacientes. La tasa de supervivencia depende en gran medida del tipo de acceso vascular utilizado. Objetivo: Determinar las complicaciones en pacientes con catéter de hemodiálisis en relación al sitio de inserción. Materiales y Métodos: Estudio de cohorte prospectivo, analítico, con medición de la frecuencia de complicaciones de pacientes con catéter de hemodiálisis a nivel yugular y femoral. Las variables se obtuvieron de los expedientes clínicos de pacientes internados ≥18 años. Resultados: Se incluyeron 203 pacientes, 66,01% masculinos; una edad media de 52 ± 15 años. 123 pacientes portaban catéter yugular y 80 pacientes, femoral. La curación se realizó cada 3 ± 5 días. La duración media de catéteres antes de signos de infección fue 4 ± 4 semanas en femorales y 9 ± 12 semanas en yugulares. Las bacterias gram positivas predominaron en los hemocultivos; aquellos con acceso femoral presentaron bacteriemia en mayor porcentaje. El cultivo de punta de catéter presentó una baja sensibilidad. Pacientes con catéter femoral presentaron mayor frecuencia de complicaciones. De las complicaciones infecciosas, la más frecuente fue el choque séptico en los portadores de catéteres femorales 57,50% vs los yugulares 4,88%. Otros: endocarditis, 7,32% en yugulares vs 2,50% en femorales; y finalmente la espondilodiscitis, con un 7,50% en femorales. La mortalidad fue mayor en aquellos con catéter femoral, 35% vs 8,94% en yugulares. Conclusión: Se ha evidenciado que el catéter femoral presenta mayor incidencia de complicaciones como choque séptico y bacteriemia, directamente relacionado con mayor tasa de mortalidad.
Introduction: More than two million people in the world receive renal replacement treatment; Blood infection represents a significant threat, being the second cause of death in these patients. The survival rate depends largely on the type of vascular access used. Objective: Determine complications in patients with hemodialysis catheter in relation to the insertion site. Materials and Methods: Prospective, analytical cohort study, measuring the frequency of complications in patients with hemodialysis catheters at the jugular and femoral levels. The variables were obtained from the clinical records of hospitalized patients ≥18 years of age. Results: 203 patients were included, 66.01% male; an average age of 52 ± 15 years. 123 patients had a jugular catheter and 80 patients had a femoral catheter. Healing was carried out every 3 ± 5 days. The mean duration of catheters before signs of infection was 4 ± 4 weeks in femoral and 9 ± 12 weeks in jugular. Gram-positive bacteria predominated in blood cultures; those with femoral access had bacteremia in a higher percentage. Catheter tip culture had low sensitivity. Patients with a femoral catheter had a higher frequency of complications. Of the infectious complications, the most frequent was septic shock in those with femoral catheters 57.50% vs jugular catheters 4.88%. Others: endocarditis, 7.32% in jugular vs 2.50% in femoral; and finally spondylodiscitis, with 7.50% in femoral bones. Mortality was higher in those with a femoral catheter, 35% vs. 8.94% in jugular catheters. Conclusion: It has been shown that the femoral catheter has a higher incidence of complications such as septic shock and bacteremia, directly related to a higher mortality rate.
Résumé
BACKGROUND:Maternal and infant mortality rates reported in rural Panama are greater than those in urban regions. Bocas del Toro is a region of Panama inhabited by indigenous people at greater risk for pregnancy-related complications and deaths due to geographic isolation and limited access to health care. Portable ultrasound training programs have recently been implemented in low-resource settings to increase access to diagnostic imaging. The goal of this study is to determine the feasibility of teaching first-year medical students the Rural Obstetrical Ultrasound Triage Exam (ROUTE) to help identify pathology in pregnant women of the Bocas del Toro region of Panama. METHODS:Eight first-year medical students completed ROUTE training sessions. After training, the students were compared to professional sonographers to evaluate their accuracy in performing the ROUTE. Students then performed the ROUTE in mobile clinics within Bocas del Toro. They enrolled women pregnant in their 2nd or 3rd trimesters and measured biparietal diameter, head circumference, amniotic fluid index, fetal lie and placental position. Any abnormal measurement would be further analyzed by the lead physician for a potential hospital referral. RESULTS:A total of 60 women were enrolled in the study. Four women were detected as having a possible high-risk pregnancy and thus referred to a hospital for further evaluation. CONCLUSION:Based on our data, first-year medical students with additional training can use the ROUTE to identify complications in pregnancy using ultrasound in rural Panama. Additional studies are required to determine the optimal amount of training required for proficiency.
