Short communication: Effect of refrigerated storage on the pH and bacterial content of pasteurized human donor milk.

Once pasteurized donor milk is thawed for its administration to a preterm or sick neonate, and until it is administered, it is kept refrigerated at 4 to 6°C for 24 h. After this time, unconsumed milk is discarded. This time has not been extended, primarily because of the concern of bacterial contamination. The aim of this study was to determine the changes in pH and bacterial count when pasteurized donor milk was kept under refrigeration for a prolonged period (14 d). In this prospective study, 30 samples of pasteurized donor milk from 18 donors were analyzed. Milk was handled following the regular operating protocols established in the neonatal unit and was kept refrigerated after thawing. pH measurements and bacteriology (on blood agar and MacConkey agar plates) were performed on each sample at time 0 (immediately after thawing) and then every day for 14 d. Changes in pH of samples over time were evaluated with linear mixed-effects regression models. A slow but gradual increase in milk pH was observed starting from the first day [mean (±SD) pH of 7.30 (±0.18) at time 0 and 7.69 (±0.2) on d 14]. No bacterial growth was observed in any of the samples throughout the complete trial except in one sample, in which Bacillus flexus was isolated. In conclusion, pasteurized human donor milk maintains its microbiological quality when properly handled and refrigerated (4-6°C). The slight and continuous increase in milk pH after the first day could be due to changes in the solubility of calcium and phosphate during refrigerated storage.

Impact of pharmaceutical validation on prescribing errors in a neonatal intensive care unit. Randomised and controlled study.

Purpose: To compare the frequency of electronic prescription errors when the prescription was validated by the clinical pharmacist vs. when it was not. Methods: This prospective randomised controlled study was conducted in three phases. A randomised phase, in which patients were divided into control and intervention groups, and a pre- and post-intervention phase were consecutively performed to analyse the impact of pharmaceutical validation of prescriptions in a neonatal intensive care unit (NICU). This study was performed at a highly complex NICU at a tertiary hospital. All patients born during the study period who were admitted to the NICU, with a stay lasting ≥24 h, and received active pharmacological treatment were included in the study. Pharmaceutical validation was performed according to the paediatric pharmaceutical care model. A high level of validation was selected for this study. In the intervention group, discrepancies found during the review process were communicated to the medical team responsible for the patients and resolved on the same day. Results: In total, 240 patients were included in this study. Sixty-two patients were allocated to the pre-intervention (n = 38) or post-intervention (n = 24) groups, and 178 patients were randomly sorted into two groups, control (n = 82 newborns) and intervention (n = 96 newborns). During the randomisation phase, the number of prescription errors detected was significantly lower in the intervention group than that in the control group (129 vs. 270; p < 0.001). Similarly, prescription errors reaching the patient were significantly reduced from 40% (n = 108) in the control group to 1.6% (n = 2) in the intervention group. In the pre- and post-intervention periods, the prescription lines containing prescription errors decreased from 3.4% to 1.5% (p = 0.005). Conclusions: This study showed that the pharmaceutical validation process decreased both the number of errors in the electronic prescribing tools and the number of prescription errors reaching the patient.

Age of sitting unsupported and independent walking in very low birth weight preterm infants with normal motor development at 2 years.

AIMS: The aims of this study is to (i) determine the age of sitting unsupported and independent walking in preterm infants with birth weight under 1500 g (very low birth weight, VLBW); (ii) estimate differences between VLBW children and a reference population and (iii) estimate the association between clinical characteristics and late age at sitting and walking. METHODS: A longitudinal study was conducted of a cohort of 876 children with VLBW. The World Health Organization (WHO) motor development study population was used as a reference. Ages for both skills were established by interview with parents. Means were compared with t-test, ANOVA and Bonferroni adjustment where appropriate. RESULTS: The inclusion criteria were complied with 694 patients; 50% of VLBW sat at 7 m corrected age (CA) and walked at 13 m CA. Both motor skills were acquired later (7.3 +/- 1.5 and 13.6 +/- 2.8 m) compared with the control group (6 +/- 1.1 and 12.1 +/- 1.8 m). Weight or head circumference at birth below the 10th percentile or the presence of bronchopulmonary dysplasia were associated with delayed acquisition of both skills. CONCLUSION: Very low birth weight infants typically sit unsupported and walk later than term infants. Tables describing reference values for milestones acquisition for different categories of infants (gestational age, birth weight and other determinants) may contribute to inform the decision making process on access to available resources.

[Retinopathy of prematurity. Prevention, screening and treatment guidelines]. / Retinopatía de la prematuridad. Recomendaciones para la prevención, el cribado y el tratamiento.

ROP screening is carried out at all the Spanish hospitals, but there is little agreement on the criteria used for its screening and other aspects related to its practice. Our aim is to report on recommendations for prevention, screening, treatment and follow-up of the retinopathy of prematurity in Spain. Prevention strategies and recommendations for screening, exploration and treatment of ROP, as well as of the organisation of the services to carry out it are reviewed. The most recent bibliography on the basis of the scientific evidence is considered, taking as reference, the guidelines published by the American Academy of Pediatrics (AAP) in 2006 and the recommendations updated in 2007 in the United Kingdom. The recommended prevention strategies are based on the best neonatal practice. The standards, as far as the screening is concerned, are established by birth weight (< or =1,500 g), gestational age (< or =32 weeks) and unstable neonatal clinical course. Indirect ophthalmoscopy is the standard technique for exploration and laser therapy the treatment of choice.

Comparison of two methods for cleaning breast pump milk collection kits in human milk banks.

BACKGROUND: Appropriate decontamination of breast pump milk collection kits (BPKs) is critical to obtain safe milk for infants and to avoid discarding donor human milk (DHM). AIM: To evaluate two strategies for BPK decontamination by assessing microbial cultures and the proportion of discarded DHM, according to the criteria of the National Institute for Health and Care Excellence for pre-pasteurization cultures. METHODS: Prospective comparative study, allocation ratio 1:1, microbiologist-blind. PARTICIPANTS: 47 new donors in a human milk bank in Madrid. INTERVENTIONS: Study group (N=21): BPKs washed with water and detergent after each use and further steam decontamination within a microwavable bag. Control group (N=26): washing, rinsing and drying only. Five samples: first sample by hand expression and four samples (one per week) collected using the same pump and method. OUTCOMES: Primary: proportion of DHM discarded due to contamination. Secondary: comparison of the microbiota between samples obtained by hand expression and breast pump in both groups. FINDINGS: In total, 217 milk samples were collected: 47 by hand expression and 170 by pump expression (78 from study group). Steam decontamination of BPKs using a microwavable bag after washing resulted in a lower proportion of discarded DHM samples (1.3% vs 18.5%, P<0.001) and samples contaminated with Enterobacteriaceae (1.3% vs 22.8%, P<0.001) and Candida spp. (1.3% vs 14.1%, P<0.05) compared with samples collected with BPKs that were washed but not steam decontaminated. There were no differences in bacterial contamination between samples obtained using steam decontaminated BPKs and those obtained by hand expression. CONCLUSIONS: Steam decontamination of BPKs using a microwavable bag after washing decreases the amount of discarded DHM and the number of samples with potentially pathogenic bacteria.

[Retinopathy of prematurity screening in Spanish neonatal units]. / Cribado de la retinopatía de la prematuridad en las unidades neonatales españolas.

INTRODUCTION: A wide variety of retinopathy of prematurity (ROP) screening criteria exists in the different hospitals. In 1988, the benefits of cryotherapy treatment in severe ROP cases were demonstrated, and since then, some scientific societies have made recommendations on the screening and treatment of ROP. Within the Spanish scientific community, there are no specific recommendations on screening, diagnosis or treatment. OBJECTIVES: To describe the criteria used in the screening of retinopathy in premature newborns by those Spanish hospitals caring for babies with birth weights below 1,500 g. MATERIAL AND METHOD: A cross-sectional study was performed based on a 50 question questionnaire on screening criteria and other related issues. This questionnaire was sent to those public and private neonatal units in Spain caring for babies with birth weights below 1,500 grams. The questionnaire was sent and returned between January 2002 and May 2003. RESULTS: Units in all of the 17 autonomous communities and both autonomous cities in territorial Spain (Ceuta and Melilla) responded. There was a 90% response rate. All the participating hospitals perform ROP screening. Only 62.9% of the hospitals follow a written protocol on screening. A large majority of hospitals (79.8%) perform a retinal eye examination on all newborns below 1500 g at birth. Half of the hospitals included in the study, 51.6%, determine the cut-off point for performing the screening at 32 weeks of gestational age. Around 73% of the hospitals include the administering of oxygen supplements to premature babies as part of the criteria for screening, regardless of the babies' weight and gestational age. Weight, gestational age and oxygen are the only criteria used in 51% of the units. That all hospitals in Spain should establish some screening criteria was suggested by 90% of the responses. Only 10% use analgesia or sedation, other than topical, when examining the retina. CONCLUSIONS: Even though all the hospitals participating in the study screen for ROP, there is little agreement on which criteria should be followed when screening and on other aspects related to its practice.

[Cerebral palsy: the concept and population-based registers]. / Parálisis cerebral: concepto y registros de base poblacional.

INTRODUCTION: Cerebral palsy (CP) is the most common cause of motor disability in the paediatric age. For several decades, a number of developed countries have kept registers that have been used to conduct population-based studies of CP. In Spain, however, little attention has been paid to the epidemiology of CP. AIM: To review the concept of CP today and to stimulate greater interest in researching into CP based on the experience of other countries. DEVELOPMENT: The different definitions of CP cover motor sequelae secondary to an isolated brain injury that occurs in a developing brain. CP registers were started as a means of monitoring the prevalence of CP and planning suitable care for patients. Over the last decade projects have been carried out that involve the coordinated efforts of several centres; this provides a larger population for study and reduces the chances of confusion with respect to the terminology employed. In this regard, one notable line of work is that of the European CP group (SCPE), which gathers information about children with CP in 15 countries. Spain has been taking part in this project since 2003 through a group of researchers from the Hospital 12 de Octubre in Madrid. CONCLUSIONS: From the very definition of the disorder, CP is a complex condition. A population-based study of CP in Spain should help to arouse a renewed interest in this condition in our country.

[Assessment of the new Ballard score to estimate gestational age]. / Valoración del test de Ballard en la determinación de la edad gestacional.

BACKGROUND AND OBJECTIVES: The New Ballard Score (NBS) is commonly used to estimate gestational age (GA) in the newborn. The aims of this study were: a) to determine the reliability of the NBS; b) to estimate the agreement between two methods of GA assessment, NBS and ultrasonography (US) or last menstrual period (LMP); c) to estimate the agreement between NBS and US/LMP in distinct subgroups of neonates. PATIENTS AND METHODS: We performed a prospective, blind study. NBS was performed in neonates born in Hospital 12 Octubre, Madrid before the age of 48 hours. The level of agreement was estimated with two analytical parameters: the intraclass correlation coefficient (ICC) and the mean differences method (MD). RESULTS: Inter-observer agreement was very good (ICC > 0.8). Agreement between US/LMP and NBS was good (ICC = 0.6-0.8). In infants with lower weight or GA, and in those whose mothers had received prenatal corticosteroid therapy, NBS tended to overestimate GA compared with US/LMP (MD = 1.2-2.9). CONCLUSIONS: The agreement between two observers in NBS assessment was very good. The agreement between NBS and US/LMP was good, but differences of more than 2 weeks in GA were frequent. In very preterm newborns and in infants whose mothers had received prenatal corticosteroid therapy, NBS tends to overestimate GA.

[The use of the continuous positive airway pressure for early stabilization in very low birthweight infants]. / Uso de la CPAP en la estabilización inicial de los niños con un peso al nacimiento menor de 1.500 g.

BACKGROUND: The introduction of continuous positive airway pressure (CPAP) in neonatal units provides a new strategy in the management of infants weighing less than 1500 g, and especially in those weighing less than 1000 g, allowing a reduction in the use of surfactant without negatively affecting prognosis. OBJECTIVES: To compare the rate of surfactant use in very low birthweight (VLBW) infants before and after the introduction of CPAP for early stabilization. To compare the frequency of pneumothorax, bronchopulmonary dysplasia (BPD), mortality, severe brain injury, length of hospital stay, and days of intubation in both groups of VLBW infants. METHODS: We performed a before-after study comparing VLBW infants born in a tertiary care hospital in two periods: group 1 consisted of 78 VLBW infants born in 2001 and group 2 consisted of 80 VLBW infants born from June 2003 to February 2004. Group 1 received conventional management (intubation and administration of surfactant in the delivery room). In group 2, CPAP was introduced for early stabilization. RESULTS: The mean weight was 1059+/-309 g in group 1 and 1127+/-295 g in group 2 (p = 0.15). The mean gestational age was 29 +/- 3.3 weeks in group 1 and 29 +/- 2.8 weeks in group 2 (p = 1). Fifty-four percent of the neonates in group 1 were intubated in the delivery room versus 31 % of those in group 2 (p = 0.004). Surfactant was used in 68 % of neonates in group 1 versus 49 % of those in group 2 (RR = 1.34 [1.06-1.83]). The mean number of days of intubation was 4 +/- 11 in group 1 versus 2.7 6 5.8 in group 2 (p 5 0.15). Bronchopulmonary dysplasia at a corrected age of 36 weeks occurred in 19 % of neonates in group 1 and in 14.5 % of those in group 2 (RR = 1.34 [0.63-2.84]). The mean number of days on oxygen was 34 6 47 and 21 6 25 respectively (p = 0.04). Necrotizing enterocolitis occurred in 3.8 % of neonates in group 1 and in 8.7 % of those in group 2 (RR= 0.43 [0.11-1.63]). The mortality rate and frequency of pneumothorax were similar in both groups. In the subgroup of VLWB infants with a gestation age of < 28 weeks, no differences were found between the two periods. CONCLUSIONS: The use of CPAP for early stabilization of VLBW infants is not associated with an increase in neonatal morbidity. This therapy allows the use of surfactant to be decreased, and even allows the number of days on oxygen to be reduced, without adverse effects. However, data on long-term follow-up are not yet available.

[Developmental centered care. Evaluation of Spanish neonatal units]. / Cuidados centrados en el desarrollo. Situación en las unidades de neonatología de España.

INTRODUCTION: Developmental and family centered care (DC) is a framework that aims to enhance the neurodevelopment of the infant. Over the last few years Spanish neonatal units have been working toward introducing this type of care. OBJECTIVE: To evaluate DC in Spanish neonatal units by assessing certain features of the care provided to very low birth weight infants and their families. MATERIAL AND METHOD: Spanish hospitals attending infants under 1,500 g were identified. A cross sectional study was performed using a telephone questionnaire with 25 DC-related items. RESULTS: Of the 100 hospitals attending infants under 1,500 g, 83 hospitals from all the Autonomous Communities in Spain participated in the survey. Of these, 31 % had noise pollution controls, 72 % controlled light intensity, 75 % bound the infants, and 29 % used saccharose as an analgesic. Ten percent allowed unrestricted parental visits. Twenty-two percent used kangaroo care without restriction. Sixty-three percent of the units reported difficulties when introducing DC-related changes. CONCLUSIONS: Practically all neonatal units have some type of DC activity, although in certain areas, such as unrestricted parental visits, the rate of implementation is low.

[Magnetic resonance imaging without sedation in neonates]. / Resonancia magnética sin sedación en recién nacidos.

INTRODUCTION: The ability to perform magnetic resonance imaging (MRI) without sedation in the neonatal period increases patient safety, availability and profitability of the diagnostic tool. The aim in this study was to evaluate a new protocol of MRI without sedation during a 20-month period. In the protocol, the patients are prepared in the neonatal unit. PATIENTS AND METHOD: Prospective descriptive study, from May 2012 to December 2013. Patients included were neonates requiring MRI, clinically stable and not requiring ventilatory support. The method was based on the application of developmental centered care and the use of a vacuum matress to immobilize the baby. The principal outcome parameter of interest was the percentage of succesfully completed MRIs. The duration of the MRI and the number of interruptions, was also studied from October 2012. RESULTS: A total of 43 MRIs without sedation were carried out on 42 patients: 41 cerebral and 2 spinal. The success rate was 97.7% (42/43). The mean MRI time was 26.3 minutes (95% CI 23.3-29.3 mins; range 16-50 mins). MRIs were completed without interruption in 20 of the 34 cases (58%) in which the duration was recorded. The number of interruptions per procedure varied from 0 to 3, with a mean of 0.6 (95% CI 0.3-0.8) and a median of 0. CONCLUSION: The protocol had a success rate of over 90%. Thus MRI without sedation seems applicable in Spanish hospitals, with most of the preparation being performed in the neonatal unit, in order to reduce the occupation of the MRI unit, as well as minimizing stress to the baby.

[Characteristics of immigrant women and their neonates]. / Características de las mujeres inmigrantes y de sus hijos recién nacidos.

BACKGROUND: Immigrant status is frequently assumed to constitute a health risk because migration is inevitably associated with a period of significant adjustment and stress. OBJECTIVE: To compare the social characteristics and perinatal outcomes of mothers who deliver in a third level hospital in Spain according to their socioeconomic level of the country of origin. METHODS: From December 2000 to March 2001, women who delivered were selected according to the socioeconomic status of their birth country. All women from low and middle income countries (immigrant mothers) and a sample (1:2) of those from high income countries (mainly Spanish-born mothers) completed a questionnaire on antenatal care, demographic and social characteristics, and country of birth and were followed-up to monitor neonatal clinical features. RESULTS: During the three months of the study, 203/1352 (15 %, CI 13.2-17.1) of the delivering mothers were immigrants. Most were from Central and South America (56 %, CI 49-62). Prenatal care was appropriate in most of the women (in 92.1 % of immigrant mothers and in 96.8 % of Spanish mothers, p 5 0.01). The proportions of premature births, low birth weight and very-low birth weight showed no statistically significant differences between immigrant and Spanish mothers (15 vs. 10.6, 6.4 vs. 9.4, and 2.1 vs. 1.5, respectively, p > 0.05 in all comparisons). Perinatal complications, including an Apgar score < or = 6, and the need for admission to the neonatal unit or to the intensive or intermediate care units, were not more frequent in the newborns of immigrant mothers. Immigrant women had less social or family support after delivery and maternity leave was much less frequent (62 % vs. 90 %, p < 0.001). CONCLUSIONS: Most of the immigrant women had healthy pregnancies and healthy birth outcomes. Perinatal complications do not seem to be more frequent among immigrant women. Differences were found in social support. To improve the health of these children, social support to immigrant women and their children should be intensified.

[Effect of freezing on the "creamatocrit" measurement of the lipid content of human donor milk]. / Medida por crematocrito del contenido calórico de la leche materna donada congelada.

OBJECTIVE: To determine, by the creamatocrit measurement, the effect on the fat content of raw and pasteurized donor milk of freezing during 3 months at -20 °C. METHODS: The evolution of the creamatocrit measurement (following Lucas technique) on frozen (-20 °C), raw and pasteurized human milk, was analyzed during 3 months. RESULTS: The fat content of raw milk (n=44) was 3.19 g/dl at the beginning and 2.86 g/dl after 3 months frozen (p=0.02). In pasteurized milk (n=36) fat content at the first determination was 2.59 g/dl and 2.20 g/dl after 1 month frozen (p=0.01). Afterwards there were no significant changes up to 3 months frozen. Variability was observed in the intermediate values. CONCLUSIONS: A reduction on the fat content measurement of raw and pasteurized donor human milk after freezing was observed. Freezing does not inactivate the milk lipase but does destroy the fat globule. Creamatocrit measurement may not be the best method to determine the fat content of processed human milk.

[Clinical impact of opening a human milk bank in a neonatal unit]. / Impacto en la práctica clínica de la apertura de un banco de leche en una unidad neonatal.

INTRODUCTION: The benefits of donor human milk compared with artificial formulas have been well demonstrated; nevertheless the impact in the clinical practice of opening a human milk bank within a neonatal unit has not yet been studied. The main aim of this study was to analyze the impact on the clinical practice of opening a human milk bank in a neonatal unit to provide donor human milk for preterm infants ≤ 32 weeks of gestational age. METHODS: A before and after study was designed, with the intervention being the opening a human milk bank. Preterm infants ≤ 32 weeks of gestational age born in the Hospital 12 Octubre from July to December 2005 and January to June 2008 (firsts 6 months after opening the human milk bank) were included. RESULTS: After opening the human milk bank, enteral feedings were started 31h before (P<.001), 100ml/kg/day were achieved 59.5h before (P<.001) and 150 ml/kg/day 52 h before (P=.002). Enteral feedings were never started LM with artificial formula, the exposure to formula in the first 15 days of life was reduced from 50% to 16.6%, and it's consumption during the first 28 days of life was significantly reduced. There was a higher consumption of own mother's milk during the hospital stay, and a higher rate of exclusive breastfeeding at hospital discharge (54% vs 40%). CONCLUSIONS: The availability of donor human milk has led to quicker progression with enteral feedings and earlier withdrawal of parenteral nutrition. It has reduced the exposure to artificial formulas, and has also increased the intake of own mother's milk during the hospital stay and the rate of exclusive breastfeeding at hospital discharge.

[Incidence of unplanned extubations in a neonatal intensive care unit. A before and after study]. / Frecuencia de extubaciones no programadas en una unidad de cuidados intensivos neonatales. Estudio antes y después.

INTRODUCTION: Unplanned extubations (UE) of mechanically ventilated newborns involves an undesirable increase in morbidity and mortality. OBJECTIVE: A 2-stage study compared the frequency of UE in a Neonatal Intensive Care Unit before and after the implementation of a program of preventive measures to decrease UE. PATIENTS AND METHODS: A before and after prospective study included all mechanically ventilated newborns participating in the 2 stage study from May-December 2011 and June-December 2012. In stage 1, the rate of UE per 100 intubated patient days was calculated and the characteristics of unplanned extubated newborns, circumstances of UE occurrence and need for re-intubation were studied. Consequently, a program of preventive measures for UE was designed and implemented, with the same variables being analysed in stage 2. RESULTS: No differences were found in patient characteristics during the two stages. Stage 1, incidence of UE was 5/100 intubated patient days; Stage 2, 4.5 UE/100 intubated patient days (P=.657). In both stages, most UE occurred during patient handling with re-intubation incidence at 77.4% and 67.7%, respectively. The combined rate of both stages during summer months of July, August and September was 6.2 UE/100 intubation days, in contrast with the remaining months of both stages: UE incidence rate, 3.4 UE/100 intubation days (p=.043). CONCLUSIONS: The implementation of a preventive measures program did not significantly reduce the incidence of UE. The summer period showed the highest incidence of UE.

[Profile of human milk bank donors and relationship with the length of the donation]. / Características de las mujeres donantes de un banco de leche materna y relación con el tiempo de donación.

INTRODUCTION: The promotion of Human Milk Banks is an important social service. The Human Milk Banks depend on donors, and knowing the profile of donors seems quite important. OBJECTIVE: To study the demographics and lifestyles of the donors, the reasons or influences for donating, and to associate these variables with the length of the donation. METHODS: This is a descriptive, cross-sectional study conducted on 168 mothers who answered the written questionnaire when they agreed to become donors. 98 (58%) responded to the telephone interview. RESULTS: The mean age was 33.1 ± 4.5 years. Of the total 27.9% lived outside Madrid and 21.4% were immigrants, with 23.7% working full time, 65.3% had a university education, and 96.2% had a stable partner. The main reasons for donating were too much milk (77%), and to help others (75%). The main obstacle was transportation to the Human Milk Bank for 20% of the donors, and for 61% the main reason for terminating donation was due to reaching the end of lactation. A longer donation is associated with: having a term newborn, with birth weight over 1500 g, starting donating early and reconciling the donation to the work situation. CONCLUSION: The most common donor profile was a young woman, with university education and a stable partner. Having a term new born, starting donating early, and the conciliation with work is associated with longer donations. Milk pick-up at home would make donation easier.

[Profile of parenteral nutrition prescription in very low birth weight infants: period 2006 to 2010]. / Perfil de prescripción de nutrición parenteral en recién nacidos de muy bajo peso al nacer: período 2006 a 2010.

INTRODUCTION: Early administration of nutrients in adequate amounts is of vital importance to preterm infants because it decreases the time needed to reach the expected weight and tolerate enteral nutrition as well as reducing their hospital stay. The main objective of this study was to analyze the prescription of parenteral nutrition (PN) in patients weighing less than 1,500 g at birth in their first 7 days of life during the years 2006-2010 in our hospital and the adequacy of those requirements to the recommendations. MATERIALS AND METHODS: Amino acids, glucose, lipids (g/ kg/day) and calories (kcal/kg/day) prescribed in the PN of the first week of life were collected. RESULTS: We studied 1899 parenteral nutrition prescriptions from 2006 to 2010 corresponding to the first week of life of 360 patients weighing less than 1,500 g. The caloric content increased from an average of 41.83 kcal/kg/day (1.89 g/kg/ day of amino acids and 0.69 g/kg/day lipids) on the first day of life to 80.61 kcal/kg/day (3.2 g/kg/day of amino acids and 2.4 g/kg/day of lipids) on the seventh day. About 70% of prescriptions for the children who had PN on the first day of life contained lipids. But when all children who had PN on the fourth day were considered, only 17% of these patients had lipid intake on the first day of life. No prescription exceeded 120 kcal/kg/day. Only 17.9% on the sixth day and 25.5% on the seventh day received more than 90 kcal/kg/day. In our hospital PN is not prepared on Sundays and holidays. 30.1% and 56.9% of children born on weekdays received PN the first and second day versus 11.6% and 38.8% of those born on a holiday or the day before holiday. CONCLUSIONS: A high percentage of premature babies do not get the recommended amounts of nutrients in their first week of life in our hospital.

[Study of anxiety levels in neonatal unit staff]. / Estudio de los niveles de ansiedad en los profesionales de una unidad neonatal.

INTRODUCTION: The professionals who routinely work in neonatal units become under stress due to the working conditions and the nature of the tasks carried out. As a consequence of this, they may have high levels of anxiety. Anxiety is defined as an emotional response or response patterns that include cognitive, physiological and behavioural aspects. METHODS: A prospective cross-sectional study was conducted on all neonatologist, nurses and care assistants who were given two self-administered questionnaires under baseline conditions, to assess Sate Anxiety and Trait Anxiety. (IDDA-EA; STAI, State-Trait Anxiety Inventory). RESULTS: The response rate was 88.5%, and 36% scored between 30 and 70 percentiles on State Anxiety, with 11.8% above the 70 percentile and 51% below the 30 percentile. There were no significant differences in relation to occupation or age. There were also no significant differences between State and Trait Anxiety. Regarding gender, it has obtained A statistically significant difference of 8 points higher was obtained for women. CONCLUSIONS: For the majority professionals everyday situations in which are involved do not significantly raise the burden of anxiety, as half of them have levels below the average. They perceive themselves as competent and able to cope with their tasks. They have a high degree of interest and attention in the activities performed.
