[Incidence of pressure ulcers due to prone position in patients admitted to the ICU for Covid-19]. / Incidencia de úlceras por presión secundarias al decúbito prono en pacientes ingresados en unidades de cuidados intensivos por SARS-CoV-2.

The appearance of pressure ulcers (PU) is one of the frequent complications of prone position (PP), due to prolonged pressure and shear forces. Objectives: To compare the incidence of pressure ulcers secondary to prone position and describe their location among four Intensive Care Units (ICU) of public hospitals. Methods: Multicenter descriptive and retrospective observational study. The population consisted of patients admitted to the ICU between February 2020 and May 2021, diagnosed with Covid-19 who required prone decubitus. The variables studied were sociodemographic, days of admission to the ICU, total hours on PP, PU prevention, location, stage, frequency of postural changes, nutrition and protein intake. Data collection was carried out through the clinical history of the different computerized databases of each hospital. Descriptive analysis and association between variables were performed using SPSS vs.20.0. Results: A total of 574 patients were admitted for Covid-19, 43.03% were pronated. 69.6% were men, median age was 66 (IQR 55-74) and BMI 30.7 (RIC 27-34.2). Median ICU stay was 28 days (IQR 17-44.2), median hours on PD per patient 48 h (IQR 24-96). The incidence of PU occurrence was 56.3%, 76.2% of patients presented a PU, the most frequent location was the forehead (74.9%). There were significant differences between hospitals in terms of PU incidence (p = 0.002), location (p < 0.001) and median duration of hours per PD episode (p = 0.001). Conclusions: The incidence of pressure ulcers due to the prone position was very high. There is great variability in the incidence of pressure ulcers between hospitals, location and average duration of hours per episode of prone position.

[Limiting and facilitating factors of changes in the care of families of the critically ill patient]. / Elementos facilitadores y limitadores del cambio en la atención a los familiares del paciente crítico.

INTRODUCTION: Participatory action research (PAR) was conducted in an intensive care unit (UCI), with the general purpose of fostering change in clinical practice so as to improve the care offered to families of critically ill patients. As a result of this process, four change-related initiatives were introduced. One specific additional objective was to explore how the unit's background context limited or facilitated change. This paper presents findings based on this objective. MATERIALS AND METHODS: Qualitative methodology. DESIGN: Participatory-action research (PAR). DATA GATHERING TECHNIQUES: 11 discussion groups incorporating professionals, 5 in-depth interviews with professionals, field diaries kept by the participants, and field diary kept by the lead researcher. Eleven professionals took part in the discussion groups (each one conveyed information made known to them by 3-5 colleagues), 5 professionals were involved in the interviews, and 11 professionals filled in a field diary. A content analysis was performed. RESULTS: Factors limiting change included: 1) Not acknowledging the legitimacy of scientific evidence regarding the families of critically ill patients; 2) Imbalanced power relationships among the members of multi-disciplinary teams; 3) Nurses' lack of involvement in information flow; 4) The organization of time and physical space in the unit. Factors facilitating change: 1) A sense of individual and shared commitment; 2) Leadership in day-to-day matters; 3) A process based on reflection. CONCLUSIONS: A process of participatory action research can lead to change in clinical practice, although this is complex and requires substantial input in terms of personal energy. Contextual factors limiting this change are related to the actual structure of the unit, while factors facilitating it are circumstantial ones and are dependent upon individual people. In this sense, professionals working at the bedside are capable of introducing changes to the context in which they work.

[Physical compatibility of sodium bicarbonate with other drugs often administered in the intensive care unit]. / Compatibilidad física del bicarbonato sódico con fármacos de uso frecuente en la unidad de cuidados intensivos.

INTRODUCTION: Acid-base disorders are associated with many diseases of the critically ill patient. Early treatment with sodium bicarbonate of these metabolic disorders is required for their normalization. This is an alkaline electrolyte solution administered by continuous or intermittent infusion. Its incompatibility due to its alkaline pH has been described, as it produces insoluble carbonate precipitation and causes carbon dioxide gas when mixed with acidic solutions. MATERIAL AND METHOD: An in vitro experimental study was performed. Bicarbonate was mixed with 13 drugs simulating Y-site administration. We combined 5 ml bicarbonate with 5 ml of every drug, at highest daily concentration used. The samples were visually examined to detect color changes, cloudiness, precipitation or gas formation, pH measurement and spectrophotometric analysis at 450 nm and 620 nm. The samples were evaluated at 0, 15, 30, 60 and 120 minutes. The compatibility criteria were absence of visual changes, pH changes<0.5 and variability of absorbance <0.01. RESULTS: We studied each drug individually and mixed with bicarbonate with 27 samples, and 135 measurements were performed. The incompatibilities did not always produce visual changes. Knowing the pH of drugs does not guarantee the compatibility of the mixture. Nitroglycerin with pH 4 is compatible with bicarbonate. Thiopental with pH 11 makes precipitation. Higher absorbances showed color changes, cloudiness and precipitation. CONCLUSIONS: Bicarbonate is physically compatible with esmolol, furosemide, heparin, insulin, morphine, nimodipine, nitroglycerin and urapidil and incompatible with amiodarone, cisatracurium, haloperidol, midazolam and thiopental.

Interprofessional collaboration in joint clinical sessions in an intensive care unit: Perceptions of nurses and physicians. / Colaboración interprofesional en las sesiones clínicas conjuntas en una Unidad de Cuidados Intensivos: percepciones de enfermeras y médicos.

INTRODUCTION: Collaborative practice is an interpersonal process in which different professional disciplines that share objectives interact, participate in decision-making and provide comprehensive and quality care. The joint clinical sessions offer the opportunity to interact and improve communication between professionals and optimise results in practice. AIM: To explore perceptions of nurses and physicians about collaborative practice in joint Intensive Care Unit clinical sessions. METHOD: Critical discourse analysis, through semi-structured interviews and field journals, using as theoretical reference the concepts of Campus, Capital and Habitus by Pierre Bourdieu. PARTICIPANTS: nurses and physicians of the Intensive Care Unit, who were recruited by intentional sampling. Semi-structured interviews were conducted and a discourse analysis was then performed. The interviews were coded by all the researchers, then shared and the data were interpreted in the context in which they were collected. RESULTS: Five categories emerged: 1) Concept: integration and involvement of a team with collective contributions and shared objectives, 2) importance: it increases patient safety, improves professional satisfaction and quality of care, 3) factors: the absence of culture organisations make collaborative practice difficult, 4) role: the nurse perceived that she plays a passive role (listener) during the clinical rounds and the physician an active role (communicator) and, 5) improvement strategies: to establish a schedule and balance interprofessional tasks. CONCLUSIONS: There is a need for empowerment in active participation by nursing staff in joint clinical sessions. The medical group should be more aware of the humanistic perceptions that other professionals can bring. Encouraging active listening in physicians, improving real communication by nursing staff and generating a space where respect and confidence prevail, will favour interprofessional work dynamics.

[Physical compatibility of furosemide in intravenous mixtures for continuous perfusion]. / Compatibilidad visual y física de la furosemida en mezclas intravenosas para perfusión continua.

INTRODUCTION: Patients in the intensive care units simultaneously receive concomitantly many drugs, with limited venous accesses. Thus, several different perfusions must be administered jointly through the same catheter. Furosemide is a solution with no buffer capacity that is easily precipitated. In spite of the recommendation on its data sheet stating that it should not be used with other drugs, studies found in the bibliography suggest that it has physicochemical compatibility with other drugs. However, the concentrations studied do not always coincide with those used in the clinical practice. OBJECTIVES: To study and verify the physical compatibility of furosemide in intravenous mixture. MATERIAL AND METHOD: An experimental study in vitro, in which furosemide was mixed with 12 drugs at a 1:1 proportion was performed. A total of 40 samples were obtained and the following variables were evaluated at different intervals, 0, 15, 30, 60 and 120 min: ph of mixture, color changes, presence of turbidity and precipitation. To do so, visual observation procedures, ph measurements and spectrophotometer absorption at 450 and 620 nm were used. RESULTS: Forty samples, 13 simples, 12 doubles and 15 triples, were obtained. Those mixtures that did not show physical changes, pH variation and absorption variation were considered compatible. CONCLUSION: Furosemide is physically compatible with bicarbonate solution, heparin, insulin, morphine and nitroglycerin and incompatible with amiodarone, cisatracurium, haloperidol, midazolam and urapidil.

Analysis of discarded blood volume for analytical extraction in ICU. / Análisis del volumen sanguíneo desechado para la extracción de analíticas en UCI.

For laboratory sample extraction through catheters, blood volume must be discarded prior to specimen collection to ensure the accuracy of the results. OBJECTIVES: To analyse the discarded blood volume obtained through vascular catheters, according to type of catheter, professional experience in extraction and hospital in Adult Intensive Care Units (ICU) of the Balearic Islands. METHOD: Cross-sectional multicentre descriptive study. Conducted from April to December 2018. Field of study: Adult Intensive Care Units of the Balearic Islands. POPULATION: 296 nurses. SAMPLE: nursing professionals who answered the survey. Data collection instrument: ad hoc, anonymous and voluntary questionnaire. Variables studied: waste volume, type of catheter, sex, professional experience and hospital. Descriptive statistical analysis, standard deviation, coefficient of variation, and non-parametric tests: Kruskal-Wallis and Median test with an CI: 95%, using the SPSS vs20.0 programme. RESULTS: 142 surveys were obtained, 12 hospitals participated: 6 public and 6 private, 72.5% women and 27.5% men. The total mean volume discarded was 5.98ml (± 3.01): peripheral venous catheter (CVP) 5.74ml (± 2.85), arterial cannula 4.37ml (± 2.93), peripheral access central catheter (PICC) 7.34ml (± 3.03) and central venous catheter (CVC) 6.49ml (± 2.99). The medians of waste volume vary greatly between the different ICUs (p <.001). Private hospitals discard larger volumes than public hospitals through CVP: 5.12ml (±2.15) vs. 6.99ml (±2.80) (p=.023), CVC: 5.92ml (±2.58) vs. 7.93ml (±1.71) (p=.026) and PICC: 6.77ml (±2.73) vs. 9.07ml (±2.05) (p=.004). CONCLUSIONS: There is a great variability in the volume of blood discarded, it depends on the hospital. No association was found between the discarded blood and the other variables studied. More conservative extraction techniques should be used.

Blood volume extracted from the critical patient in the first 24 hours after admission. / Volumen de sangre extraído al paciente crítico las primeras 24h de ingreso.

OBJECTIVE: To calculate the number of analytical tests and blood volume drawn during the first 24hours of admission to the Intensive Care Unit (ICU). To analyse values of basal haemoglobin and at 24hours, relate them to blood loss, weight variation, and scoring system. METHOD: An observational descriptive pilot study. Variables studied: age, sex, diagnosis on admission, analytical tests extracted, waste quantity before the extraction of samples, total volume blood extracted in 24hours, weight variation, APACHE, SAPS, basal haemoglobin and at 24hours. Statistical analysis with SPSS vs 20.0. Variables correlation sex, weight variation, the number of analytical tests and haemoglobin change. RESULTS: The study included 100 patients. The average number of extractions per patient/day was 7.2 (±2.6). The average waste quantity was 32.61ml (±15.8). The blood volume used for determinations was 48.18ml / 24h (±16.74). The haemoglobin value decreased in the first 24hours of admission, being higher in men (P<.05). The scoring systems were statistically significant for levels of haemoglobin (Hb1 -0.3; P=.001; Hb2 -0.4; P=.001). CONCLUSIONS: Of the total volume of blood extracted in ICU, 40% belongs to a volume of waste and 60% of blood is used for analytical tests. There is a decrease in haemoglobin exists 24hours after admission of the critical patient. Statistically, it has not been possible to demonstrate its relation with the number of analytical tests.

[Patient safety in antibiotics administration: Risk assessment]. / Seguridad del paciente en la administración de antibióticos: evaluación del riesgo.

OBJECTIVE: To determine the level of risk in the preparation and administration of antibiotics frequently used in the Intensive Care Unit using a risk matrix. MATERIAL AND METHOD: A study was conducted using situation analysis and literature review of databases, protocols and good practice guidelines on intravenous therapy, drugs, and their administration routes. The most used antibiotics in the ICU registered in the ENVIN-HELICS program from 1 April to 30 June 2015 were selected. In this period, 257 patients received antimicrobial treatment and 26 antibiotics were evaluated. Variables studied: A risk assessment of each antibiotic using the scale Risk Assessment Tool, of the National Patient Safety Agency, as well as pH, osmolarity, type of catheter recommended for administration, and compatibility and incompatibility with other antibiotics studied. RESULTS: Almost two-thirds (65.3%) of antibiotics had more than 3 risk factors (represented by a yellow stripe), with the remaining 34.7% of antibiotics having between 0 and 2 risk factors (represented by a green stripe). There were no antibiotics with 6 or more risk factors (represented by a red stripe). Most drugs needed reconstitution, additional dilution, and the use of part of the vial to administer the prescribed dose. CONCLUSION: More than half of the antibiotics studied had a moderate risk level; thus measures should be adopted in order to reduce it. The risk matrix is a useful tool for the assessment and detection of weaknesses associated with the preparation and administration of intravenous antibiotics.

[Perception of privacy in patients hospitalized in an Intensive Care Unit]. / Percepción de la intimidad en pacientes hospitalizados en una Unidad de Cuidados Intensivos.

INTRODUCTION: The Intensive Care Unit (ICU) is an impersonal and technologically invasive setting. The rules and framework of the unit favor a lack of privacy, an inherent fact for every kind of hospitalization. The objectives of the study are to know the experience of patients admitted to the ICU in relation to the perception of privacy and its impact on their own experience. MATERIAL AND METHODS: Phenomenological qualitative methodology. The participants were patients admitted to the ICU of Son Dureta University Hospital in Palma de Mallorca, who were older than 18 with a minimum stay of 48 hours and who had signed an informed consent. Data collection. By exhaustive semi-structured interviews. Content analysis. RESULTS: The perception of privacy in patients admitted to the ICU is described in relationship with surrounding physical space, family setting and privacy autonomy. The patients evaluated the flexibility of rules, professionalism of the nursing staff and the need for family support when the situation is more stable. CONCLUSION: To prevent the quality of nursing cares from only depending on their technological knowledge and ability, but also depends on the humane side of caring, it is extremely important to consider the different elements that mould the experience of being admitted to the ICU and respect of the privacy of each person.
