Workloads of intensive care nurses. Validity of their estimation using mobile applications and comparison with Nursing Activities Score. Systematised review of the literature.

INTRODUCTION: Adjusting human resources to intensive care units (ICU) workload is essential. The development of software for estimating nursing workload using mobile devices (smartphone, smartwatch and/or tablets) could be a useful tool and complement and/or improve the measurements made with the Nursing Activities Score (NAS), a validated scale. OBJECTIVES: To analyze the validity of devices and mobile applications for estimating ICU nurses' workloads and their comparison with NAS. METHODOLOGY: Systematised literature review from 2009 to 2021 informed by flowchart PRISMA-2020 and its extension PRISMA-S. Critical reading (CASPe). Steps:elaboration of the research question, concept identification (English and Spanish natural language and descriptors MesH, Emtree and CINAHL Headings), search strategy and data collection in MEDlars online (MEDLINE), OVID, Excerpta Medica dataBASE (EMBASE), Elsevier, Cumulative Index to Nursing & Allied Health Literature (CINAHL), EBSCO and Web of Science (WoS); data extraction and evaluation, analysis and synthesis of results. We included studies with abstracts published in English and Spanish conducted in ICU with workload measurement (preferably NAS) using mobile devices. RESULTS: 223 studies of which 84 in MEDLINE, 50 in CINAHL, 48 in EMBASE, 33 in WOS and 8 in other sources. 117 were eligible for screening, of which 95 did not meet the inclusion criteria. 22 studies were screened for eligibility, of which 17 were excluded. Five articles were selected for final review. None of the studies provided results on costs, acceptance testing, validity, reliability, system problems, advantages, disadvantages or resource estimation. DISCUSSION AND CONCLUSIONS: The use of mobile devices and applications to measure ICU workloads is not yet validated and has not been shown to be more accurate than traditional NAS assessment.

Predictive validity of the Clinical Frailty Scale-España on the increase in dependency after hospital discharge.

INTRODUCTION: The frailty present at hospital admission and the stressors to which patients are subjected during their stay may increase dependency at hospital discharge. OBJECTIVES: To assess the predictive validity of the Clinical Frailty Scale-España (CFS-Es) on increased dependency at 3 and 12 months (m) after hospital discharge. METHODOLOGY: Multicentre cohort study in 2020-2022. Including patients with >48 h stay in intensive care units (ICU) and non-COVID-19. VARIABLES: pre-admission frailty (CFS-Es). Sex, age, days of stay (ICU and hospital), dependency on admission and at 3 m and 12 m after discharge (Barthel index), muscle weakness (Medical Research Council Scale sum score <48), hospital readmissions. STATISTICS: descriptive and multivariate analysis. RESULTS: 254 cases were included. Thirty-nine per cent were women and the median [Q1-Q3] age was 67 [56-77] years. SAPS 3 on admission (median [Q1-Q3]): 62 [51-71] points. Frail patients on admission (CFS-Es 5-9): 58 (23%). Dependency on admission (n = 254) vs. 3 m after hospital discharge (n = 171) vs. 12 m after hospital discharge (n = 118): 1) Barthel 90-100: 82% vs. 68% vs. 65%. 2) Barthel 60-85: 15% vs. 15% vs. 20%. 3) Barthel 0-55: 3% vs. 17% vs. 15%. In the multivariate analysis, adjusted for the variables recorded, we observed that frail patients on admission (CFS-Es 5-9) are 2.8 times (95%CI: 1.03-7.58; p = 0.043) more likely to increase dependency (Barthel 90-100 to <90 or Barthel 85-60 to <60) at 3 m post-discharge (with respect to admission) and 3.5 times (95%CI: 1.18-10.30; p = 0.024) more likely to increase dependency at 12 m post-discharge. Furthermore, for each additional CFS-Es point there is a 1.6-fold (95%CI: 1.01-2.23; p = 0.016) greater chance of increased dependency in the 12 m following discharge. CONCLUSIONS: CFS-Es at admission can predict increased dependency at 3 m and 12 m after hospital discharge.

Assessment of analgesia, sedation, physical restraint and delirium in patients admitted to Spanish intensive care units. Proyecto ASCyD. / Valoración de la analgesia, sedación, contenciones y delirio en los pacientes ingresados en unidades de cuidados intensivos españolas. Proyecto ASCyD.

AIMS: Main aim: To determine the Spanish intensive care units (ICU) that assess and record pain levels, sedation/agitation, delirium and the use of physical restraint (PR) as standard practice. Secondary aims: To determine the use of validated assessment tools and to explore patients' levels of pain and sedation/agitation, the prevalence of delirium, and the use of PR. METHOD: An observational, descriptive, cross-sectional, prospective and multicentre study using an ad hoc survey with online access that consisted of 2 blocks. Block I: with questions on the unit's characteristics and routine practice; Block II: aspects of direct care and direct assessments of patients admitted to participating units. RESULTS: One hundred and fifty-eight units and 1574 patients participated. The pain of communicative patients (CP) was assessed and recorded as standard in 109 units (69%), the pain of non-communicative patients (NCP) in 84 (53%), sedation/agitation in 111 (70%), and delirium in 39 units (25%). There was recorded use of PR in 39 units (25%). Validated scales were used to assess the pain of CP in 139 units (88%), of NCP in 102 (65%), sedation/agitation in 145 (92%), delirium in 53 units (34%). In 33 units (21%) pain, sedation/agitation and delirium of PC and NPC was assessed, and in 8 of these units there was a specific PR protocol and register. Among the patients who could be assessed, an absence of pain was reported in 57%, moderate pain in 27%; 48% were calm and collaborative, and 10% agitated; 21% had PR, and 12.6% of the patients had delirium. CONCLUSIONS: The assessment of pain, sedation and delirium is demonstrated, and low percentages of agitation and delirium achieved. We observed a high percentage of patients with pain, and moderate use of PC. We should generalise the use of protocols to assess, prevent and treat pain and delirium by appropriately managing analgesia, sedation, and individual and well-considered use of PC.

Analysis of a nurses' knowledge survey on the use of physical restraint in intensive care units. / Análisis de una encuesta sobre conocimientos en contenciones mecánicas de las enfermeras de unidades de críticos.

OBJECTIVES: To determine nurses' knowledge level regarding physical restraint use in intensive care units and its associated factors. METHOD: A cross-sectional multicentre study was carried out in 12 critical care units of 8 hospitals in Spain (n=354 nurses). An 'ad-hoc' knowledge survey was developed, and their content was validated by experts. The survey obtained a test-retest stability of ICC=.71 (95% CI: .57-.81) in a previous pilot study. A final 8-item tool was designed. Sociodemographic and professional variables from the participants were collected; as well as structural and clinical variables from the units analyzed. A descriptive and association analysis between variables was performed. A p-value <.05 was deemed statistically significant. RESULTS: Two hundred and fifty nurses answered the survey (70.62%). Mean age of the participants was 36.80 (SD 9.54) with 10.75 (SD 8.38) years of professional experience in critical care. Seventy-three point six percent had never received previous training about physical restraints. Knowledge mean value was 4.21 (SD 1.39) (range 0-8). Knowledge level was associated with the referral hospital (p<.001). Nurses with a higher knowledge level are more likely to work in units with informed consent sheets for physical restraint use (p<.001); flexible family visiting (p<.001); analgo-sedation protocol (p=.011), and units in which nurses had autonomy to manage analgo-sedation (p<.001). Individual sociodemographic and professional data was not associated with knowledge level. CONCLUSIONS: Further training regarding physical restraint use is needed for critical care nurses. The work environment where nursing care is given has a great influence on nurses' knowledge level about this intervention.

Effect of a training programme on blood culture contamination rate in critical care. / Efecto de una acción formativa en cuidados intensivos sobre la tasa de contaminación de hemocultivos.

Blood culture contamination can occur from extraction to processing; its rate should not exceed 3%. OBJECTIVE: To evaluate the impact of a training programme on the rate of contaminated blood cultures after the implementation of sample extraction recommendations based on the best evidence. METHOD: Prospective before-after study in a polyvalent intensive care unit with 18 beds. Two phases were established (January-June 2012, October 2012-October 2015) with a training period between them. Main recommendations: sterile technique, surgical mask, double skin disinfection (70° alcohol and 2% alcoholic chlorhexidine), 70° alcohol disinfection of culture flasks and injection of samples without changing needles. Including all blood cultures of patients with extraction request. VARIABLES: demographic, severity, pathology, reason for admission, stay and results of blood cultures (negative, positive and contaminated). Basic descriptive statistics: mean (standard deviation), median (interquartile range) and percentage (95% confidence interval). Calculated contamination rates per 100 blood cultures extracted. Bivariate analysis between periods. RESULTS: Four hundred and eight patients were included. Eight hundred and forty-one blood cultures were taken, 33 of which were contaminated. In the demographic variables, severity, diagnosis and stay of patients with contaminated samples, no differences were observed from those with uncontaminated samples. Pre-training vs post-training contamination rates: 14 vs 5.6 per 100 blood cultures extracted (P=.00003). CONCLUSION: An evidence-based training programme reduced the contamination of samples. It is necessary to continue working on the planning of activities and care to improve the detection of pollutants and prevent contamination of samples.

Ecchymosis and/or haematoma formation after prophylactic administration of subcutaneous enoxaparin in the abdomen or arm of the critically ill patient. / Formación de equimosis y/o hematoma tras la administración profiláctica de enoxaparina subcutánea en abdomen o brazo en pacientes críticos.

INTRODUCTION: Ecchymosis and/or haematoma are the most common adverse events after subcutaneous administration of low molecular weight heparin. There is no strong recommendation as to the puncture site. OBJECTIVE: To evaluate the adverse events, ecchymosis and/or haematoma after the administration of prophylactic subcutaneous enoxaparin in the abdomen vs the arm in the critically ill patient. METHODOLOGY: A randomised, two-arm clinical trial (injection in the abdomen vs the arm), performed between July 2014 and January 2017, in an 18-bed, polyvalent intensive care unit. Patients receiving prophylactic enoxaparin, admitted >72h, with no liver or haematological disorders, a body mass index (BMI) >18.5, not pregnant, of legal age and with no skin lesions which would impede assessment were included. We excluded patients who died or who were transferred to another hospital before completing the evaluation. We gathered demographic and clinical variables, and the onset of ecchymosis and/or haematomas at the injection site after 12, 24, 48 and 72hours. A descriptive analysis was undertaken, with group comparison and logistic regression. The study was approved by the ethics committee with the signed consent of patients/families. RESULTS: 301 cases (11 excluded): 149 were injected in the abdomen vs 141 in the arm. There were no significant differences in demographic and clinical variables, BMI, enoxaparin dose or antiplatelet administration [ecchymosis, abdomen vs arm, n(%): 66(44) vs 72(51), P=.25] [haematoma abdomen vs arm, n(%): 9(6) vs 14(10), P=.2]. Statistical significance was found in the size of the haematomas after 72h: [area of haematoma (mm2) abdomen vs arm, median (IQR): 2(1-5.25) vs 20(5.25-156), P=.027]. CONCLUSIONS: In our patient cohort, prophylactic subcutaneous enoxaparin administered in the abdomen causes fewer haematomas after 72hours, than when administered in the arm. The incidence rate of ecchymosis and haematoma was lower than the published incidence in critically ill patients, although patients receiving anti-platelet agents present a higher risk of injury. No relationship was observed in relation to BMI.

Psychometric validation of the behavioral indicators of pain scale for the assessment of pain in mechanically ventilated and unable to self-report critical care patients.

OBJECTIVE: To assess the psychometric properties of the behavioral indicators of pain scale (ESCID) when applied to a wide range of medical and surgical critical patients. DESIGN: A multicentre, prospective observational study was designed to validate a scale measuring instrument. SETTING: Twenty Intensive Care Units of 14 hospitals belonging to the Spanish National Health System. PARTICIPANTS: A total of 286 mechanically ventilated, unable to self-report critically ill medical and surgical adult patients. PROCEDURE: Pain levels were measured by two independent evaluators simultaneously, using two scales: ESCID and the behavioral pain scale (BPS). Pain was observed before, during, and after two painful procedures (turning, tracheal suctioning) and one non-painful procedure. MAIN VARIABLES: ESCID reliability was measured on the basis of internal consistency using the Cronbach-α coefficient. Inter-rater and intra-rater agreement were measured. The Spearman correlation coefficient was used to assess the correlation between ESCID and BPS. RESULTS: A total of 4386 observations were made in 286 patients (62% medical and 38% surgical). High correlation was found between ESCID and BPS (r=0.94-0.99; p<0.001), together with high intra-rater and inter-rater concordance. ESCID was internally reliable, with a Cronbach-α value of 0.85 (95%CI 0.81-0.88). Cronbach-α coefficients for ESCID domains were high: facial expression 0.87 (95%CI 0.84-0.89), calmness 0.84 (95%CI 0.81-0.87), muscle tone 0.80 (95%CI 0.75-0.84), compliance with mechanical ventilation 0.70 (95%CI 0.63-0.75) and consolability 0.85 (95%CI 0.81-0.88). CONCLUSION: ESCID is valid and reliable for measuring pain in mechanically ventilated unable to self-report medical and surgical critical care patients. CLINICALTRIALS.GOV: NCT01744717.

[Validating the Spanish version of the Nursing Activities Score]. / Validación de la versión en castellano del Nursing Activities Score.

INTRODUCTION: Validating workload scores ensures that they are appropriate for the purpose for which they were developed. OBJECTIVE: To validate the Nursing Activities Score (NAS) Spanish version. METHODOLOGY: Observational and prospective study. 1,045 patients who were admitted to a medical-surgical unit and a serious burns unit in 2006 were included. The nurse in charge assessed patient workloads by Nine Equivalent of Nursing Manpower use Score and NAS. To assess the internal consistency of the measurements of NAS, item-test correlations, Cronbach's α and Cronbach's α corrected by omitting each of the items were calculated. The intraobserver and interobserver reliability were assessed with the intraclass correlation coefficient by viewing recordings and Kappa (interobserver reliability) was estimated. For the analysis of internal validity, a factorial principal components analysis was performed. Convergent validity was assessed using the Spearman correlation coefficient values obtained from the Nine Equivalent of Nursing Manpower use Score and Spanish-NAS scales. RESULTS: For internal consistency, 164 questionnaires were analysed and a Cronbach's α of 0.373 was calculated. The intraclass correlation coefficient for intraobserver reliability estimate was 0.837 (95% IC: 0.466-0.950) and 0.662 (95% IC: 0.033-0.882) for interobserver reliability. The estimated kappa was 0.371. For internal validity, exploratory factor analysis showed that the first item explained 58.9% of the variance of the questionnaire. For convergent validity 1006 questionnaires were included and a Spearman correlation coefficient of 0.746 was observed. CONCLUSIONS: The psychometric properties of Spanish-NAS are acceptable.

[Interobserver reliability of the Glasgow coma scale in critically ill patients with neurological and/or neurosurgical disease]. / Fiabilidad interobservador de la escala del coma de Glasgow en pacientes críticos con enfermedad neurológica o neuroquirúrgica.

INTRODUCTION: The Glasgow coma scale (GCS) is a common tool used for neurological assessment of critically ill patients. Despite its widespread use, the GCS has some limitations, as sometimes different observers may value differently the same response. OBJECTIVE: To evaluate the interobserver agreement, among intensive care nurses with a minimum of 3 years experience, both in the overall estimate of GCS and for each of its components. METHODS: Prospective observational study including 110 neurological and/or neurosurgical patients conducted in a critical care unit of 18 beds, from October 2010 until December 2012. Registered variables: Demographic characteristics, reason for admission, overall GCS and its components. The neurological evaluation was conducted by a minimum of 3 nurses. One of them applied an algorithm and consensual assessment technique and all, independently, valued response to stimuli. Interobserver agreement was measured using the intraclass correlation coefficient (ICC) for a confidence interval (CI) of 95%. The study was approved by the Ethics Committee for Clinical Trails. RESULTS: The intraclass correlation coefficient (confident interval) for scale was: Overall GCS: 0.989 (0.985-0.992); ocular response: 0.981 (0.974-0.986); verbal response: 0.971 (0.960-0.979); motor response: 0.987 (0.982-0.991). CONCLUSION: In our cohort of patients we observed a high level of consistency in the application of both the GCS as in each of its components.

Adaptación transcultural al castellano del Nursing Activities Score / Transcultural adaptation into Spanish of the Nursing Activities Score

Introducción La valoración de las cargas de enfermería es práctica habitual en el trabajo diario de los cuidados enfermeros, y normalmente se hace utilizando escalas ajenas al medio hispanoparlante, sin tener en cuenta las características de los distintos entornos que difieren de un país a otro. Entre los instrumentos utilizados para la valoración de las cargas de trabajo en enfermería en unidades de cuidados intensivos, Nursing Activities Score (NAS) ha sido descrito como un instrumento útil para medir dichas cargas en estas unidades. Objetivo Adaptar al castellano el NAS para su uso en unidades de cuidados intensivos. Material y métodos Adaptación por el método de traducción-retraducción del NAS mediante traductores de idioma materno inglés y bilingüe (castellano), y traductores con el castellano como idioma materno y alto nivel de inglés, trabajando los traductores por separado. Se obtuvo una versión única en castellano con la que se realizó una prueba piloto en la Unidad de Cuidados Intensivos y Grandes Quemados del Hospital Universitario de Getafe (Madrid, España) con 30 pacientes y 30 enfermeros durante su turno habitual de trabajo. Se consultó, también, con el autor principal del NAS los ítems que supusieron algún tipo de conflicto. Resultados Entre la escala original y la resultante de las retrotraducciones en inglés se obtuvo una buena correspondencia en el 73% de los ítems y una correspondencia apropiada en el restante 27%; ningún ítem fue considerado con correspondencia mala. Conclusión Se ha obtenido una versión adaptada en castellano del NAS (AU)

Introduction Assessment of nursing workload is a common practice in the daily work of nursing care. This is usually done using scales that were not designed for Spanish-speaking countries, which may not take into account the characteristics of the environments that differ from one country to another. The Nursing Activities Score (NAS) has been described as being a useful tool for measuring nursing workload among the instruments used for this measurement in intensive care units. Objective It was aimed to adapt the NAS into Spanish for its use in Spanish intensive care units. Material and methods The NAS was adapted using translation-back translation method with the participation of both native English speakers who were bilingual in Spanish, and Spanish translators with a high level of English. All of the translators worked individually. A single Spanish version of the scale was obtained, after which a pilot test was made in an Intensive Care Major Burns Unit of the University Hospital of Getafe (Madrid, Spain) with 30 patients and 30 nurses during their regular work shift. We also consulted the primary author of the original description of the NAS regarding items that caused some kind of conflict. Results Between the original scale and the result of the back-translations to English, we obtained agreement ratings of good in 73%, and appropriate in the remaining 27%. No item was considered to have bad correspondence. Conclusion We have developed a Spanish translation of the NAS that appears well matched to the original English version (AU)

[Establishment of a nursing-driven sedation protocol: effect on the sedation level and accidental withdrawal of tubes and catheters]. / Implementación de un protocolo de sedación dirigido por enfermería: efecto sobre el nivel de sedación y la retirada accidental de tubos y catéteres.

INTRODUCTION: Mechanically ventilated patients require sedation during ventilatory support. Our study has aimed to determine if the effects on the sedation level of a nursing-driven sedation protocol has any influence in the accidental removal of tubes and catheters. MATERIAL AND METHODS: A quasi-experimental intervention study was performed in a medical-surgical intensive care unit. A 17-month pre-intervention observational period was followed by a 17-month intervention period where a nursing-driven sedation protocol based on the Glasgow Coma Score modified by Cook and Palma was implemented. In both periods, we registered the accidental removals of endotracheal tube, nasogastric tube, urinary catheter and intravascular catheters. RESULTS: A total of 176 patients (age: 65 +/- 17 years; SAPS II: 43 +/- 14) were included in the observation period and 189 patients (age: 65 +/- 15 years; SAPS II: 40 +/- 13) in the intervention period. In second period, the percentage of patients excessively sedated decreased (20% vs. 41%; p = 0.001) and the percentage of patients with optimal sedation increased (53% vs. 35%; p < 0.001). The rate of accidental removals of enteral tubes in the first period was 15.8 per 1,000 tube-days vs. 5.6 in the second period (p = 0.001). No accidental removal of intravascular catheters was found in the second period vs. a rate of 2.6 central venous catheters per 1,000 catheter-days and a rate of 3.4 intra-arterial catheters per 1,000 catheter-days during the first period. CONCLUSIONS: Implementation of a nursing-driven sedation protocol increases the percentage of patients with an optimal sedation and decreases the incidence of accidental removal of tubes and catheters.

[Reliability of the measurement of glucose at the bedside of critical patients]. / Fiabilidad de la determinación de la glucemia a la cabecera del paciente en pacientes críticos.

INTRODUCTION: The objective of this study is to measure the reliability of three measurement methods at the bedside of the patient, of glucose in the critical patient compared with the measurement of glucose in the central laboratory. MATERIAL AND METHODS: Observational, perspective study developed in a polyvalent unit of 18 beds for four months. Patients who had arterial catheter were included. Eight samples obtained at the patient's bedside were compared with the plasma glucose (gold Standard): three in capillary blood, four in arterial blood and one in arterial blood gases from a syringe. The measurements at bedside were conducted with reactive strips MediSense Optium Plus and glucometer MediSense Optium. A comparison was made of the means used in the Student's T test and Bland and Altman analysis. RESULTS: We obtained 630 samples in 70 patients. Mean glucose (SD) in mg/dl was: a) capillary samples: 149 (38), 149 (35), 147 (37); b) arterial samples: 140 (34), 142 (35), 143 (35), 142 (34); arterial gas sample syringe: 143 (33); c) plasma glucose: 138(33). There were significant differences (p < 0.001) between plasma glucose and capillary samples but not with arterial samples (p=0.2). In the arterial samples, the presence of some factors, such as vasoactive drugs, glycated solution perfusion, insulin perfusion and plasma concentration of hemoglobin, increase error and dispersion regarding the gold standard. CONCLUSIONS: The measurement of glucose at bedside in critical patients is more reliable in arterial samples than in capillary ones.

Introducción. El objetivo de este estudio es determinar la fiabilidad de tres métodos de determinación, a pie de cama, de la glucemia en el paciente crítico comparados con la determinación de glucemia en el laboratorio central. Material y métodos. Estudio observacional prospectivo desarrollado en una Unidad polivalente de 18 camas durante 4 meses. Se incluyeron pacientes que portaban catéter arterial. Se compararon con la glucemia plasmática (patrón oro) 8 muestras obtenidas a la cabecera del paciente: tres en sangre capilar, 4 en sangre arterial y una de sangre arterial en jeringa de gases. Las determinaciones a la cabecera fueron realizadas con tiras reactivas MediSense® Optium™ Plus y glucómetro MediSense® Optium™. Se realizó una comparación de medias mediante la prueba de la «t» de Student y análisis de Bland y Altman. Resultados. Obtuvimos 630 muestras en 70 pacientes. La glucemia media (desviación estándar [DE]) en mg/dl fue: a) muestras capilares: 149 (38), 149 (35), 147 (37); b) muestras arteriales: 140(34), 142 (35), 143 (35), 142 (34); muestra arterial en jeringa de gases: 143 (33); c) glucemia plasmática: 138 (33). Hubo diferencias significativas (p < 0,001) entre la glucemia plasmática y las muestras capilares, pero no con las muestras arteriales (p = 0,2). En las muestras arteriales la presencia de algunos factores, como fármacos vasoactivos, perfusión de soluciones glucosadas, perfusión de insulina y concentración plasmática de hemoglobina, aumenta el error y la dispersión respecto al patrón oro. Conclusiones. En enfermos críticos la medida de la glucemia a pie de cama es más fiable en muestras arteriales que en muestras capilares

A comparison was made of the means used in the Student's T test and Bland and Altman analysis. Results. We obtained 630 samples in 70 patients. Mean glucose (SD) in mg/dl was: a) capillary samples: 149 (38), 149 (35), 147 (37); b) arterial samples: 140 (34), 142 (35), 143 (35), 142 (34); arterial gas sample syringe: 143 (33); c) plasma glucose: 138(33). There were significant differences (p < 0.001) between plasma glucose and capillary samples but not with arterial samples (p=0.2). In the arterial samples, the presence of some factors, such as vasoactive drugs, glycated solution perfusion, insulin perfusion and plasma concentration of hemoglobin, increase error and dispersion regarding the gold standard. Conclusions. The measurement of glucose at bedside in critical patients is more reliable in arterial samples than in capillary ones

Linfangiectasia intestinal, enfermedad de Waldmann y gestación / Intestinal lymphagiectasis- Waldmann disease and pregnancy

La enfermedad de Waldmann o linfangiectasia intestinal primitiva es una enteropatía exudativa producida por anomalía de los canales linfáticos de la pared intestinal. Existen formas familiares de transmisión autosómica dominante. El tratamiento dietético que aporta triglicéridos de cadena media ha modificado su evolución. Esta afección aparece en la primera infancia, pero observaciones de alteración más precoz han sido publicadas, entre ellas un caso diagnosticado prenatalmente. Aportamos un caso de paciente afectada de enfermedad de Waldmann que tuvo una gestación a término sin mayores complicaciones, lo que confirma que el embarazo no agrava la evolución de una enteropatía exudativa, como ha sido demostrado por varios autores (AU)
