Técnicas «Lean» para la mejora del flujo de los pacientes críticos de una región sanitaria con epicentro en el servicio de medicina intensiva de un hospital de referencia / Lean techniques to improve the flow of critically ill patients in a health region with its epicenter in the intensive care unit of a reference hospital

OBJETIVO: Analizar si la aplicación de técnicas «Lean» mejora el flujo de pacientes críticos de una región sanitaria, tomando como epicentro el servicio de medicina intensiva (UCI) del hospital de referencia. DISEÑO: Estudio observacional con análisis pre y postintervención. ÁMBITO: UCI del hospital de referencia. PACIENTES: Diseñamos proyectos y un mapa de flujo y comparamos características pre y postintervención. INTERVENCIONES: Registramos datos demográficos, de traslados de pacientes por el SEM por falta de camas y los tiempos de demora en la hora de alta de la UCI a planta de hospitalización. Realizamos reuniones multidisciplinarias y panel visual diario, con priorización de altas de UCI. Promovimos la reubicación temporal de pacientes críticos en otras áreas especiales del hospital. Cuestionario de satisfacción profesional con valoración pre y postintervención. Análisis estadístico de las comparaciones pre y postintervención. RESULTADOS: Se planificó durante 2013 y se implementó de forma progresiva en 2014. Las medidas principales fueron: 1) análisis de la entrada de pacientes al flujo del proceso de críticos, evaluando los pacientes que deben trasladarse por falta de camas, centrados en un diagnóstico y un área: 10/22 pre vs. 3/21 post (p = 0,045); 2) análisis del tiempo de demora en la hora de alta de UCI a planta de hospitalización: 360,8 ± 163,9 min en el primer periodo vs. 276,7 ± 149,5 en el segundo (p = 0,036); y 3) cuestionario de satisfacción profesional personal, con 6,6 ± 1,5 puntos pre vs. 7,5 ± 1,1 en post (p = 0,001). Análisis de los indicadores de UCI, como son las infecciones adquiridas, los días de estancia, la tasa de reingresos y la mortalidad, sin diferencias significativas entre ambos periodos. CONCLUSIONES: La aplicación de técnicas ‘Lean’ en el proceso de críticos tuvo un impacto positivo en la mejora del flujo de pacientes dentro de la región sanitaria, observando una disminución de los traslados fuera de la región por falta de camas, una reducción en la demora del alta de UCI a hospitalización convencional y un aumento de la satisfacción de los profesionales de la UCI de referencia

OBJECTIVE: To analyze whether the application of Lean techniques to improve the flow of critically ill patients in a health region with its epicenter in the intensive care unit (ICU) of a reference hospital. DESIGN: Observational study with pre and post intervention analysis. SETTING: ICU of a reference hospital. PATIENTS: We design projects and a value stream map of flow and compared pre and post intervention. INTERVENTIONS: We recorded demographic data, patient transfers by EMS for lack of beds and delay times in the discharge from ICU to ward. Multidisciplinary meetings and perform daily visual panel, with high priority ICU discharge. We promote temporary relocation of critically ill patients in other special areas of the hospital. We performed a professional satisfaction questionnaire with pre and post implementation of process. We make a statistical analysis of pre and post-intervention comparisons. Results: We planned for 2013 and progressively implemented in 2014. Analysis of patients entering the critical process flow 1) evaluate patients who must transfer for lack of beds, focusing on a diagnosis: pre 10/22 vs. 3/21 post (P = .045); 2) analysis of time delay in the discharge from the ICU to ward: 360.8 ± 163.9 minutes in the first period vs. 276.7 ± 149.5 in the second (P = .036); and 3) personal professional satisfaction questionnaire, with 6.6 ± 1.5 points pre vs. 7.5 ± 1.1 in post (P = .001). Analysis of indicators such as the ICU acquired infections, length of ICU stay, the rate of re-admissions and mortality, with no significant differences between the two periods. Conclusions: The application of Lean techniques in the critically ill process had a positive impact on improving patient flow within the health region, noting a decrease of transfers outside the region due to lack of beds, reduced delayed discharge from ICU to conventional ward and increased satisfaction of ICU professionals

[Pregnancy and partum in the woman with a spinal cord lesion in chronic phase]. / Embarazo y parto en la mujer con lesión medular en fase crónica.

A 34-year-old pregnant paraplegic woman with a T12 medullary lesion in chronic phase underwent cesarean delivery in the thirty-seventh week due to pelvic-cephalic disproportion. After failure of epidural anesthesia related to technical difficulties, general anesthesia was provided. A hypertensive crisis developed during surgery but was resolved within minutes after administration of hydralazine. No further complications arose. Pregnancy in a patient with medullary lesion in chronic phase is considered high risk, requiring special care due to extraordinary changes in pathophysiology caused by the lesion in addition to changes directly related to gestation. The main complications that arise are decreased respiratory volume and arterial pressure, increased incidence of thromboembolic events, anemia, urinary tract infections, premature birth, unusual progression of delivery and autonomic hyperreflexia, which is the most serious. When a hypertensive peak develops in such patients, the anesthesiologist must first rule out autonomic hyperreflexia, which has an incidence of 85% in lesions over T7 and has also been described in patients with lower lesions.

Embarazo y parto en la mujer con lesión medular en fase crónica / Pregnancy and childbirth in a woman with chronic phase medullary lesion

Gestante parapléjica de 34 años con lesión medular en T12 en fase crónica, sometida a una cesárea por desproporción pélvico-cefálica en la semana 37 de gestación.Tras fallo de la anestesia epidural por importantes dificultades técnicas, se practicó anestesia general. En el transcurso de la intervención presentó una crisis hipertensiva que se resolvió en pocos minutos tras la administración de hidralacina. La evolución posterior de la madre y del recién nacido cursaron sin incidencias.La gestación en una paciente con lesión medular en fase crónica es considerada de alto riesgo y precisa cuidados especiales debido a los extraordinarios cambios fisiopatológicos que ocurren como resultado de la lesión, a los que hay que sumar los propios del embarazo. Las principales complicaciones que presentan son: disminución de los volúmenes respiratorios y de la presión arterial, aumento de la incidencia de fenómenos tromboembólicos, anemia, infecciones del tracto urinario, parto prematuro, alteración en la progresión del parto y la hiperreflexia autónoma, que es la más grave.Ante un pico hipertensivo en estas pacientes, hay que descartar en primer lugar la hiperreflexia autónoma, que tiene una incidencia del 85 por ciento en lesiones por encima de T7 y también se ha descrito en lesiones torácicas bajas (AU)

[Nasal ketamine compared with nasal midazolam in premedication in pediatrics]. / Comparación de la ketamina con el midazolam por vía nasal en la premedicación en pediatría.

OBJECTIVE: To compare the efficacy and side effects of midazolam and ketamine administered nasally for pediatric premedication. PATIENTS AND METHODS: In this double blind trial 60 children scheduled for elective surgery were randomly assigned to two groups to receive 0.25 mg.kg or 5 mg.kg nasal ketamine. We measured level of acceptance of medication, sedation, hemodynamic variables, reaction to separation from parents, side effects and time until recovery from anesthesia. RESULTS: The two groups were homogeneous. Acceptance of medication was good or adequate in all patients. The level of sedation was significant in both groups 10 min after premedication. Systolic arterial pressure was higher in the ketamine group 20 min after administration of the drug and upon arrival in the operating theater. Reaction to separation from parents was good in all groups. Secretions were higher in the ketamine group and hallucinations were experienced by three patients in the ketamine group and by two in the midazolam group. We found no difference in time until spontaneous eye opening after surgery. No complications were observed. CONCLUSIONS: The nasal route is adequately accepted by children. Both drugs are effective by this route and sedation is rapid. Time until postanesthetic recovery is similar with both drugs. The doses used have wide safety margins.
