Incidence of incontinence-associated dermatitis in hospitalised neonates. Adaptation and validation of a severity scale.

INTRODUCTION: Up to 60% of hospitalised neonates may develop incontinence-associated dermatitis (IAD). Our aim was to adapt the Clinical Evaluation Scale for Characterization of the Severity of Diaper Dermatitis to the Spanish population and to find out the nationwide frequency of IAD in hospitalized neonates. METHODS: Cross-cultural adaptation and assessment of content validity of the scale. We carried out a prospective, multicentre observational study of the incidence of nappy rash in postnatal wards and neonatal intensive care units in 6 Spanish hospitals. RESULTS: We obtained a content validity index of 0.869 for the total scale (95% CI, 0.742-0.939). The sample included 196 neonates. The cumulative incidence of IAD was 32.1% (9.1% mild-moderate, 8% moderate and 1.6% severe). The incidence rate was 2.2 IAD cases per 100 patient days. A stool pH of less than 5.5, a greater number of bowel movements a day, a greater daily urine output and the use of oral drugs were among the factors associated with the development of IAD. CONCLUSION: The Spanish version of the Clinical Evaluation Scale for Characterization of the Severity of Diaper Dermatitis had an adequate content validity for the assessment of DAI in the hospitalised neonatal population. Mixed feeding, treatment with oral drugs and the use of medical devices in the perianal area were associated with an increased risk of nappy dermatitis in infants.

An Explanatory Model of Vascular Access Care Quality: Results of a Cross-Sectional Observational Study.

The management of nursing care regarding patients' vascular access is a priority. This study determines the contribution of the variables involved in the quality of care and maintenance of vascular access (VA) devices in admitted patients in the Valencian Community. METHODS: Using the STROBE statement, an observational, cross-sectional study was conducted on 1576 VA devices. Data were collected using the INCATIV Questionnaire. We performed a multivariate analysis of the questionnaire variables. RESULTS: In total, 50% had a good or very good assessment of the VA condition. This was positively correlated with anatomical location, dressing type, dressing date record, use of needle-free connectors (NFCs), date of last dressing change, presence of phlebitis, visibility of the insertion site and characteristics of the dressing's condition (p < 0.001). The model indicated that the presence of phlebitis was the clearest predictor of a poor VA care assessment (OR = 20.579), followed by no visibility of the insertion site (OR = 14.209). Results also indicated that uncovered VA lumens or no NFCs used were related to a negative quality assessment. CONCLUSION: By managing and controlling these variables, the likelihood of providing optimal care is ensured. This enables the establishment of a standardised care approach for all nursing professionals and the building of a new quality indicator.

Considerations about the inhibition of monophenolase and diphenolase activities of tyrosinase. Characterization of the inhibitor concentration which generates 50 % of inhibition, type and inhibition constants. A review.

Tyrosinase is a copper oxidase enzyme which catalyzes the first two steps in the melanogenesis pathway, L-tyrosine to L-dopa conversion and, then, to o-dopaquinone and dopachrome. Hypopigmentation and, above all, hyperpigmentation issues can be originated depending on their activity. This enzyme also promotes the browning of fruits and vegetables. Therefore, control of their activity by regulators is research topic of great relevance. In this work, we consider the use of inhibitors of monophenolase and diphenolase activities of the enzyme in order to accomplish such control. An experimental design and data analysis which allow the accurate calculation of the degree of inhibition of monophenolase activity (iM) and diphenolase activity (iD) are proposed. The IC50 values (amount of inhibitor that causes 50 % inhibition at a fixed substrate concentration) can be calculated for the two activities and from the values of IC50M (monophenolase) and IC50D(diphenolase). Additionally, the strength and type of inhibition can be deduced from these values. The data analysis from these IC50D values allows to obtain the values of [Formula: see text] or [Formula: see text] , or and [Formula: see text] from the values of IC50M. In all cases, the values of the different must satisfy their relationship with IC50M and IC50D.

Quality assessment in initial paediatric trauma care: Systematic review from prehospital care to the paediatric intensive care unit.

BACKGROUND: Trauma is the most common cause of death and disability in the paediatric population. There are a huge number of variables involved in the care they receive from health care professionals. AIM: The aim of this study was to review the available evidence of initial paediatric trauma care throughout the health care process with a view to create quality indicators (QIs). STUDY DESIGN: A systematic review was performed from Cochrane Library, Medline, Scopus and SciELO between 2010 and 2020. Studies and guidelines that examined quality or suggested QI were included. Indicators were classified by health care setting, Donabedian's model, risk of bias and the quality of the publication with the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) assessment. RESULTS: The initial search included 686 articles, which were reduced to 22, with 15 primary and 7 secondary research articles. The snowball sampling technique was used to add a further seven guidelines and two articles. From these, 534 possible indicators were extracted, summarizing them into 39 and grouping the prehospital care indicators as structure (N = 5), process (N = 12) and outcome (N = 3) indicators and the hospital care indicators as structure (N = 4), process (N = 10) and outcome (N = 6) indicators. Most of the QIs have been extracted from US studies. They are multidisciplinary and in some cases are based on an adaptation of the QIs of adult trauma care. CONCLUSIONS: There was a clear gap and large variability between the indicators, as well as low-quality evidence. Future studies will validate indicators using the Delphi method. RELEVANCE TO CLINICAL PRACTICE: Design a QI framework that may be used by the health system throughout the process. Indicators framework will get nurses, to assess the quality of health care, detect deficient areas and implement improvement measures.

Targeting tyrosinase in hyperpigmentation: Current status, limitations and future promises.

Hyperpigmentation is a common and distressing dermatologic condition. Since tyrosinase (TYR) plays an essential role in melanogenesis, its inhibition is considered a logical approach along with other therapeutic methods to prevent the accumulation of melanin in the skin. Thus, TYR inhibitors are a tempting target as the medicinal and cosmetic active agents of hyperpigmentation disorder. Among TYR inhibitors, hydroquinone is a traditional lightening agent that is commonly used in clinical practice. However, despite good efficacy, prolonged use of hydroquinone is associated with side effects. To overcome these shortcomings, new approaches in targeting TYR and treating hyperpigmentation are desperately requiredessentialneeded. In line with this purpose, several non-hydroquinone lightening agents have been developed and suggested as hydroquinone alternatives. In addition to traditional approaches, nanomedicine and nanotheranostic platforms have been recently proposed in the treatment of hyperpigmentation. In this review, we discuss the available strategies for the management of hyperpigmentation with a focus on TYR inhibition. In addition, alternative treatment options to hydroquinone are discussed. Finally, we present nano-based strategies to improve the therapeutic effect of drugs prescribed to patients with skin disorders.

ntroducción: La ventilación mecánica no invasiva es una técnica de amplio uso en las unidades de cuidados intensivos neonatales que ha demostrado su efectividad en la disminución de la mortalidad. Estos sistemas generan una presión prolongada en la zona de la cara del recién nacido que favorece la aparición de lesiones por presión. Se estima que casi la mitad de las lesiones por presión en las unidades de cuidados intensivos neonatales se producen por estos sistemas. Objetivos: Analizar la incidencia y los factores de riesgo de lesiones Por presión en neonatos portadores de ventilación mecánica no invasiva ingresados en la Unidad de Cuidados Intensivos Neonatales del Hospital Clínico Universitario de Valencia. Metodología: Estudio de cohortes, observacional, analítico, longitudinal y prospectivo. Llevado a cabo en la Unidad de Cuidados Intensivos Neonatales del Hospital Clínico Universitario de Valencia entre los meses de febrero y mayo de 2019. Resultados: La muestra del estudio fue de 34 neonatos, de los que 7 (el 20,59%) fueron incidentes de lesiones por presión. Del total de pacientes con lesión, 4 (el 57,1%) eran portadores de vástagos nasales, 3 (el 42,9%) utilizaban cánulas RAM®. Ningún paciente portador de gafas de oxigenoterapia de alto flujo fue incidente de lesiones por presión. Conclusiones: El uso de las gafas de alto flujo y las cánulas RAM® frente a los vástagos nasales fue un método más efectivo en la reducción de la incidencia de lesiones por presión en neonatos portadores de ventilación mecánica no invasiva (AU)

Introduction: Non-Invasive Mechanical Ventilation (NIV) is one of the most widely used clinical devices in neonates in Neonatal Intensive Care Units (NICU). This has shown its effectiveness in reducing the mortality of these children. However, these systems generate a prolonged pressure in certain anatomical parts of the newborn that favors the appearance of pressure injuries (LPP). It is estimated that almost half of pressure injuries in Neonatal Intensive Care Units are caused by these systems. Objectives:To analyze the incidence and risk factors of pressure injury in neonates at the Neonatal Intensive Care Unit of the Hospital Clinico Universitario de Valencia with Non-Invasive Mechanical Ventilation. Methodology: it is a cohort, observational, analytical, longitudinal and prospective study. Carried out in the neonatal ICU of the Hospital Clínico Universitario de Valencia between the months of February and May 2019. Results: The study sample was 34 neonates, of which 7 (20.59%) developed a pressure injury. Of the total number of patients with injury, 4 (57.1%) were carriers of nasal stems. 3 (42.9%) wore RAM cannulas and no one of patients with High Flow Oxygen Therapy Glasses developed a pressure ulcer. Conclusions: The use of High Flow glasses and RAM Cannulas against nasal stems as a method of reducing the incidence of pressure injuries in neonates with Non-Invasive Mechanical Ventilation (AU)

Training, management, and quality of nursing care of vascular access in adult patients: The INCATIV project.

BACKGROUND: More than one billion of peripheral venous catheters are inserted into hospitalized patients every year. This study sought to identify the status of nursing care in vascular accesses in different hospitals and to evaluate the impact of a series of informative and formative interventions aimed at their care. METHODS: Quasi-experimental, multicenter study. A total of 54 nursing professionals of 19 hospitals participated. The intervention consisted of informative talk and three training sessions related to the care and maintenance of vascular accesses and intravenous therapy in the hospital-admitted adult population. This was delivered in four years, with eight periodic cross-sectional assessments conducted before and after each intervention. To assess quality of nursing care in vascular accesses and intravenous therapy, a quality indicator called Standard Variable (VES), was developed and validated with the Delphi methodology. RESULTS: A total of 21,108 patients, aged 64.0 years (SD 18.3), were assessed, of which 78.3% (16,516) had some type of vascular access inserted. An average of 22.1% (95% CI: 21.4-22.7) were classified as optimal. In total, 3218 nursing care professionals took part in the training activities. The VES indicator grew steadily throughout the study, raising from 7.8% to 37.6%. Changes were statistically significant between those time points in which one of the described interventions was delivered; however, there were no significant changes between time points with no intervention. CONCLUSIONS: This study supports that continuous training interventions can produce improvements in the quality of nursing care and reduce complications in patients with vascular accesses. In addition, the VES indicator was a useful and simple tool to measure quality, but the experience with its use suggests continuous research in the search for standardized indicators that objectify the evaluation and evolution of care.

The Relationship between the IC50 Values and the Apparent Inhibition Constant in the Study of Inhibitors of Tyrosinase Diphenolase Activity Helps Confirm the Mechanism of Inhibition.

Tyrosinase is the enzyme involved in melanization and is also responsible for the browning of fruits and vegetables. Control of its activity can be carried out using inhibitors, which is interesting in terms of quantitatively understanding the action of these regulators. In the study of the inhibition of the diphenolase activity of tyrosinase, it is intriguing to know the strength and type of inhibition. The strength is indicated by the value of the inhibition constant(s), and the type can be, in a first approximation: competitive, non-competitive, uncompetitive and mixed. In this work, it is proposed to calculate the degree of inhibition (iD), varying the concentration of inhibitor to a fixed concentration of substrate, L-dopa (D). The non-linear regression adjustment of iD with respect to the initial inhibitor concentration [I]0 allows for the calculation of the inhibitor concentration necessary to inhibit the activity by 50%, at a given substrate concentration (IC50), thus avoiding making interpolations between different values of iD. The analytical expression of the IC50, for the different types of inhibition, are related to the apparent inhibition constant (KIapp). Therefore, this parameter can be used: (a) To classify a series of inhibitors of an enzyme by their power. Determining these values at a fixed substrate concentration, the lower IC50, the more potent the inhibitor. (b) Checking an inhibitor for which the type and the inhibition constant have been determined (using the usual methods), must confirm the IC50 value according to the corresponding analytical expression. (c) The type and strength of an inhibitor can be analysed from the study of the variation in iD and IC50 with substrate concentration. The dependence of IC50 on the substrate concentration allows us to distinguish between non-competitive inhibition (iD does not depend on [D]0) and the rest. In the case of competitive inhibition, this dependence of iD on [D]0 leads to an ambiguity between competitive inhibition and type 1 mixed inhibition. This is solved by adjusting the data to the possible equations; in the case of a competitive inhibitor, the calculation of KI1app is carried out from the IC50 expression. The same occurs with uncompetitive inhibition and type 2 mixed inhibition. The representation of iD vs. n, with n=[D]0/KmD, allows us to distinguish between them. A hyperbolic iD vs. n representation that passes through the origin of coordinates is a characteristic of uncompetitive inhibition; the calculation of KI2app is immediate from the IC50 value. In the case of mixed inhibitors, the values of the apparent inhibition constant of meta-tyrosinase (Em) and oxy-tyrosinase (Eox), KI1app and the apparent inhibition constant of metatyrosinase/Dopa complexes (EmD) and oxytyrosinase/Dopa (EoxD), KI2app are obtained from the dependence of iD vs. n, and the results obtained must comply with the IC50 value.

Anticancer Activity of the Choline Kinase Inhibitor PL48 Is Due to Selective Disruption of Choline Metabolism and Transport Systems in Cancer Cell Lines.

A large number of different types of cancer have been shown to be associated with an abnormal metabolism of phosphatidylcholine (PC), the main component of eukaryotic cell membranes. Indeed, the overexpression of choline kinase α1 (ChoKα1), the enzyme that catalyses the bioconversion of choline to phosphocholine (PCho), has been found to associate with cell proliferation, oncogenic transformation and carcinogenesis. Hence, ChoKα1 has been described as a possible cancer therapeutic target. Moreover, the choline transporter CTL1 has been shown to be highly expressed in several tumour cell lines. In the present work, we evaluate the antiproliferative effect of PL48, a rationally designed inhibitor of ChoKα1, in MCF7 and HepG2 cell lines. In addition, we illustrate that the predominant mechanism of cellular choline uptake in these cells is mediated by the CTL1 choline transporter. A possible correlation between the inhibition of both choline uptake and ChoKα1 activity and cell proliferation in cancer cell lines is also highlighted. We conclude that the efficacy of this inhibitor on cell proliferation in both cell lines is closely correlated with its capability to block choline uptake and ChoKα1 activity, making both proteins potential targets in cancer therapy.

Considerations about the Continuous Assay Methods, Spectrophotometric and Spectrofluorometric, of the Monophenolase Activity of Tyrosinase.

With the purpose to obtain the more useful tyrosinase assay for the monophenolase activity of tyrosinase between the spectrofluorometric and spectrophotometric continuous assays, simulated assays were made by means of numerical integration of the equations that characterize the mechanism of monophenolase activity. These assays showed that the rate of disappearance of monophenol (VssM,M) is equal to the rate of accumulation of dopachrome (VssM,DC) or to the rate of accumulation of its oxidized adduct, originated by the nucleophilic attack on o-quinone by a nucleophile such as 3-methyl-2-benzothiazolinone (MBTH), (VssM, A-ox), despite the existence of coupled reactions. It is shown that the spectrophotometric methods that use MBTH are more useful, as they do not have the restrictions of the L-tyrosine disappearance measurement method, of working at pH = 8 and not having a linear response from 100 µM of L-tyrosine. It is possible to obtain low LODM (limit of detection of the monophenolase activity) values with spectrophotometric methods. The spectrofluorimetric methods had a lower LODM than spectrophotometric methods. In the case of 4-hydroxyphenil-propionic acid, the LODM obtained by us was 0.25 U/mL. Considering the relative sensitivities of 4-hydroxyanisole, compared with 4-hydroxyphenil-propionic acid, LODM values like those obtained by fluorescent methods would be expected.

Evaluation of interface pressure and temperature management in five wheelchair seat cushions and their effects on user satisfaction.

BACKGROUND: Factors such as the manufacturing materials, shape or even the mechanical and thermal response of sitting Pressure Redistribution Support Surfaces (PRSS) can be potential contributors to pressure ulcers. However, few studies have compared a number of characteristics of the most frequently used devices. OBJECTIVE: To compare three potential contributors to pressure ulcers in five commercial PRSS: pressure redistribution, temperature and perceived comfort. METHOD: Study with a cross-over randomized design in healthy volunteer participants. Data was collected in a temperature and relative humidity controlled environment. To assess thermal response, the temperature (Flir-E60) of the region of interest was captured before and after use of each PRSS for further analysis. The region of interest was the gluteal zone. To assess the pressure redistribution a pressure mat (XSensor®) was used between the 5 cushion and each study participant using a standardized method. Finally, a subjective perception questionnaire recorded comfort, adaptability and thermal sensation parameters. Data analysis levels of significance were set at 0.05. RESULTS: A total of 22 participants completed the assessments. There were no statistically significant differences in baseline temperatures between PRSS (>0.05). Pressure redistribution analysis showed significant differences between all PRSS in all variables evaluated except in the maximum and peak pressure index al sacrum. The subjective assessment suggested no major user-perceived differences between PRSS. CONCLUSION: Seat cushions made of open cell polyurethane foam blocks of variable hardness and the horseshoe cushion (also open cell polyurethane foam) seem to provide a more effective pressure relief characteristic than those injected with polyurethane foam and gel in most of the studied pressure variables. However, the cushions provide similar thermal response and perceived comfort.

Psychological Impact on the Nursing Professionals of the Rioja Health Service (Spain) Due to the SARS-CoV-2 Virus.

BACKGROUND: The COVID-19 pandemic is a public health emergency that has affected health professionals around the world, causing physical and mental exhaustion with a greater probability of developing mental disorders in professionals who provide healthcare. OBJECTIVE: The objective of this study was to know the psychological impact of the SARS-CoV-2 virus on the nursing professionals working for the Rioja Health Service. METHODS: We conducted an observational and descriptive cross-sectional study. The nursing staff at the Rioja Health Service were invited to respond to a self-administered questionnaire between June and August 2020. RESULTS: A total of 605 health professionals participated in the questionnaire; 91.9% were women, 63.14% were registered nurses, and 36.28% were auxiliary nurses. Risk factors for mental health professionals were identified in more than 90% of nurses (p = 0.009), affecting their psychological state with feelings of exhaustion, emotional overload (p = 0.002), and less use of coping strategies among women. Younger professionals with less experience had higher levels of stress compared to those with more than five years of experience, who showed a progressive reduction in the impact of stressors (p < 0.001). Professionals with dependent family members presented higher levels of emotional overload and coping problems (p = 0.009). CONCLUSION: The COVID-19 pandemic has had a significant psychological impact on health professionals in terms of stress, emotional well-being, and the use of coping strategies. Female health professionals with dependents, a temporary contract, and less work experience have been more psychologically affected.

Effectiveness of mechanical diagnosis and therapy in patients with non-specific chronic low back pain: a literature review with meta-analysis.

OBJECTIVE: To determine the effectiveness of mechanical diagnosis and therapy (MDT) in patients with chronic low back pain (CLBP) compared to other traditional physical therapy interventions. METHODS: Randomized controlled trials investigating the effect of MDT compared to other traditional physical therapy interventions in individuals with CLBP were considered eligible. For the purpose of this review, MDT was compared to active and passive physical therapy interventions. Independent reviewers assessed the eligibility of studies, extracted data, and assessed the risk of bias. The primary outcomes investigated were pain and disability. RESULTS: Fourteen studies were included in the review. Of these, 11 provided data to be included in the meta-analyses. Our findings showed that MDT was no more effective in decreasing pain (standardized mean difference [SMD]=0.01, 95% confidence interval [CI]: -0.44, 0.46) and disability (SMD=0.08, 95% CI: -0.53, 0.68) than other active treatments. Similar results were found when comparing MDT to other passive treatments for pain (SMD=-0.39, 95% CI: -0.90, 0.11) and disability (SMD=-0.13, 95% CI: -0.29, 0.03). CONCLUSION: There is low to moderate quality evidence that MDT is not superior than other traditional physical therapy interventions in improving pain and disability in people with CLBP.

Prevention of pressure injuries in critically ill children: A preliminary evaluation.

AIMS: To evaluate a prevention strategy implemented to reduce incidence and severity of positioning related pressure injuries affecting pediatric patients in a pediatric critical care unit. Secondary objective was to evaluate compliance with preventive recommendations. BACKGROUND: The skin in infants or children has important physiological and anatomical differences compared with adults. Further, factors such as the immaturity of the skin and limited activity and mobility in pediatric critical care unit, along with the pressure exerted by medical devices, increases the risk of pressure ulcers in infants and children. The most effective preventive measures specific to this intensive care population need to be evaluated. MATERIAL AND METHODS: Quasi-experimental before-after study with consecutive sampling. The effectiveness of the care bundle implementation was evaluated based on the latest evidence (intervention group) versus the application of non-standardized care (control group). Pediatric patients up to 14 years old at risk of suffering from pressure injuries and who were admitted more than 48 h in a pediatric intensive care unit (level III) participated. For the collection of data, two computer programs and the hospital clinical records of each participant were consulted. The data collection period was 6 months per group (pre and post intervention). RESULTS: A sample of 110 patients was obtained (50 control group and 60 intervention group). The cumulative incidence in pediatric patients exposed to the risk of pressure injuries was reduced from 16% to 13.3%; and in the subgroup of patients with prolonged stay (≥28 days), the incidence was reduced from 55.55% to 20%. In the intervention group, category III and IV pressure ulcers were completely reduced. In addition, the total number of pressure injuries decreased by 21.43%. The care bandle recommendations with the highest level of adhesion recorded were: skin inspection, application of hyperoxygenated fatty acids and use of a special support surface. The main risk factor found during the study was the prone position (p < 0.05). CONCLUSIONS: The application of a care bundle for prevention can be an effective solution to reduce the number and severity of LPPs in an intensive care unit. The most vulnerable subgroup of patients may benefit from the application of these resources.

Efectividad de las medidas y estrategias de prevención de úlceras por presión en neonatos / Effectiveness of measures and strategies for the prevention of pressure ulcers in neonates

OBJETIVOS: Analizar la efectividad, en términos de disminución de la incidencia de úlceras por presión (UPP), de las medidas y estrategias preventivas de UPP en neonatos hospitalizados. MÉTODO: La recuperación de estudios se realizó a través de tres bases de datos (Medline a través de PubMed, Scopus y Science Direct) y a partir de un experto. Solamente se incluyeron en esta revisión los estudios publicados del 2007 al 2017 en español o inglés, que de forma directa o indirecta valoraran la efectividad de una medida o estrategia preventiva de UPP en neonatos hospitalizados y que en cuanto al diseño fueran o estudios clínicos controlados o cuasiexperimentales. RESULTADOS: De 100 estudios recuperados se realizó el análisis de cinco; los demás fueron excluidos por no cumplir los criterios de elegibilidad. La mayoría de los estudios analizan la efectividad de una medida preventiva de UPP secundaria al tratamiento con ventilación mecánica no invasiva en neonatos prematuros. Todos ellos tienen limitaciones en la metodología que emplean, lo que hace que la evidencia de sus recomendaciones sea baja-moderada. CONCLUSIONES: Es necesaria la realización de estudios controlados aleatorios de mayor potencia para poder recomendar alguna medida o estrategia preventiva

Objetives: The main objective of this review was to examine the effectiveness, in terms of reducing the incidence of pressure ulcers (PU), of measures and preventive strategies of PU in hospitalized infants. METHOD: The recovery of studies was carried out through three databases (Medline through Pubmed, Scopus and Science Direct), and from an expert. Only studies published from 2007-2017 in Spanish or English were included in this review, which directly or indirectly appreciate the effectiveness of a measure or preventive strategy of PU in hospitalized neonates and that in terms of design were controlled or quasi-experimental trials. RESULTS: From 100 retrieved studies was conducted analysis of 5 studies, others were excluded for failing to meet the eligibility criteria. Most studies analyze the effectiveness of a preventive measure of secondary PU to treatment with Noninvasive mechanical ventilation in preterm infants. All of the studies have limitations in the methodology used, which makes the evidence of its recommendations to be low-moderate. CONCLUSIONS: Is necessary the realization of randomized controlled studies of higher power to be able to recommend any measure or preventive strategy

Prevención de úlcereas por presión en neonatos con ventilación mecánica no invasiva / Prevention of pressure ulcers in neonates with non-invasive mechanical ventilation

OBJETIVO: Determinar el apósito con mayor efectividad (hidrocoloide o espuma de poliuretano) en neonatos ingresados en las unidades de cuidados intensivos neonatal y pediátrica del Hospital Clínico Universitario de Valencia, sometidos a ventilación mecánica no invasiva para la prevención de úlceras por presión nasales y/o faciales. MATERIAL Y MÉTODOS: Proyecto de investigación de tipo observacional, prospectivo y analítico cuya muestra estaba formada por 13 neonatos con ventilación mecánica no invasiva, hospitalizados en la unidad de cuidados intensivos neonatales y pediátrica. Los neonatos fueron divididos en dos grupos: en el grupo A (7 pacientes) se empleó el apósito de espuma de poliuretano y en el grupo B se utilizó el hidrocoloide (6 pacientes). La recogida de datos se realizó durante el período comprendido entre abril y mayo de 2018. RESULTADOS: De los neonatos incluidos en el estudio, 5 (38,5%) presentaron úlceras por presión nasales; el resto (62%) no presentó úlceras. Además, se obtuvo que, del total de pacientes con lesión, un 60% llevaba el apósito hidrocoloide y un 40% el de espuma de poliuretano. CONCLUSIONES: Tras el estudio, se determinó que el apósito de espuma de poliuretano presentaba un menor porcentaje de aparición de UPP en comparación con el hidrocoloide. Sin embargo, sería recomendable valorar la posibilidad de emplear alguno de ellos como medida de protección

MATERIAL AND METHODS: observational, prospective and analytical research project whose sample considered of 13 neonates with non-invasive mechanical ventilation hospitalized in the Neonatal and Pediatric Intensive Care Unit. They were divided into two groups, where group A (7 patients) used the polyurethane foam dressing and group B used the hydrocolloid dressing (6 patients). The data collection was carried out during the period from April to May 2018. RESULTS: Of the neonates included in the study, 5 presented nasal pressure ulcers (38.5%) and the rest did not (62%). In addition, it was obtained that, of the total of patients with injury, 60% wore the hydrocolloid dressing and 40% that of polyurethane foam. CONCLUSIONS: After the study, it was determined that the polyurethane foam dressing had a lower percentage of appearance of pressure ulcers compared to the hydrocolloid. However, it would be advisable to appraise the possibility of using any of them as a protection measure
