Prospective determination of plasma imipenem concentrations in critically ill children.

Plasma imipenem concentrations were measured in 19 critically ill children (median age, 0.8 year; range, 0.02 to 12.9 years). Wide interindividual variations (2 to 4x at peak and >10x at trough concentrations) resulted in unpredictable plasma levels in several children. To avoid subtherapeutic drug levels, we recommend treatment with at least 100 mg/kg of body weight/day of imipenem-cilastatin for critically ill children requiring such therapy.

Effects of enteral carbohydrates on de novo lipogenesis in critically ill patients.

BACKGROUND: Conversion of glucose into lipid (de novo lipogenesis; DNL) is a possible fate of carbohydrate administered during nutritional support. It cannot be detected by conventional methods such as indirect calorimetry if it does not exceed lipid oxidation. OBJECTIVE: The objective was to evaluate the effects of carbohydrate administered as part of continuous enteral nutrition in critically ill patients. DESIGN: This was a prospective, open study including 25 patients nonconsecutively admitted to a medicosurgical intensive care unit. Glucose metabolism and hepatic DNL were measured in the fasting state or after 3 d of continuous isoenergetic enteral feeding providing 28%, 53%, or 75% carbohydrate. RESULTS: DNL increased with increasing carbohydrate intake (f1.gif" BORDER="0"> +/- SEM: 7.5 +/- 1.2% with 28% carbohydrate, 9.2 +/- 1.5% with 53% carbohydrate, and 19.4 +/- 3.8% with 75% carbohydrate) and was nearly zero in a group of patients who had fasted for an average of 28 h (1.0 +/- 0.2%). In multiple regression analysis, DNL was correlated with carbohydrate intake, but not with body weight or plasma insulin concentrations. Endogenous glucose production, assessed with a dual-isotope technique, was not significantly different between the 3 groups of patients (13.7-15.3 micromol * kg(-1) * min(-1)), indicating impaired suppression by carbohydrate feeding. Gluconeogenesis was measured with [(13)C]bicarbonate, and increased as the carbohydrate intake increased (from 2.1 +/- 0.5 micromol * kg(-1) * min(-1) with 28% carbohydrate intake to 3.7 +/- 0.3 micromol * kg(-1) * min(-1) with 75% carbohydrate intake, P: < 0. 05). CONCLUSION: Carbohydrate feeding fails to suppress endogenous glucose production and gluconeogenesis, but stimulates DNL in critically ill patients.

Pulse oximetry and transcutaneous oxygen tension for detection of hypoxemia in critically ill infants and children.

We tested the performance of transcutaneous oxygen monitoring (TcPO2) and pulse oximetry (tcSaO2) in detecting hypoxia in critically ill neonatal and pediatric patients. In 54 patients (178 data sets) with a mean age of 2.4 years (range 1 to 19 years), arterial saturation (SaO2) ranged from 9.5 to 100%, and arterial oxygen tension (PaO2) from 16.4 to 128 mmHg. Linear correlation analysis of pulse oximetry vs measured SaO2 revealed an r value of 0.95 (p less than 0.001) with an equation of y = 21.1 + 0.749x, while PaO2 vs tcPO2 showed a correlation coefficient of r = 0.95 (p less than 0.001) with an equation of y = -1.04 + 0.876x. The mean difference between measured SaO2 and tcSaO2 was -2.74 +/- 7.69% (range +14 to - 29%) and the mean difference between PaO2 and tcPO2 was +7.43 +/- 8.57 mmHg (range -14 to +49 mmHg). Pulse oximetry was reliable at values above 65%, but was inaccurate and overestimated the arterial SaO2 at lower values. TcPO2 tended to underestimate the arterial value with increasing PaO2. Pulse oximetry had the best sensitivity to specificity ratio for hypoxia between 65 and 90% SaO2; for tcPO2 the best results were obtained between 35 and 55 mmHg PaO2.

Una proposta d’ensenyament aprenentatge basada en l’aprenentatge cooperatiu i el wiki com a eina afavoridora del treball compartit en els estudis de magisteri.

Presentem una experiència que s'ha desenvolupant en la diplomatura de Magisteri de la FPCEE Blanquerna de la URL durant els cursos 2008/09 i 2009/10 en el marc del procés d'implantació dels crèdits ECTS en els futurs graus d'Educació Primària. Aquesta forma part dels projectes seleccionats i finançats per al disseny, la planificació i l’avaluació de mòduls docents i seminaris dels nous plans d'estudis de grau. L'objectiu principal del projecte ha estat organitzar i experimentar l’ensenyament i l’aprenentatge des de dues assignatures de tercer curs de l’especialitat d’Educació Primària amb un enfocament metodològic interdisciplinari basat en l’aprenentatge en equips cooperatius amb el suport TIC. Cada curs han participat uns 60 estudiants distribuïts en 12 grups de treball cooperatiu. Per a l’ elaboració i seguiment del treball, s'ha escollit utilitzar els Wikis com a eina que facilita el treball cooperatiu, i així tant el professorat implicat en el projecte com cada grup ha creat el seu wiki a wikispaces: http://www.wikispaces.com/site/for/teachers i GoogleDocs per a la implementació i recollida d'informació de les tutories de seguiment i avaluació del treball fet pels estudiants. Finalment, hem analitzat i valorat el grau de satisfacció dels estudiants i professorat que ha participat tant en el disseny com en el desplegament de l'experiència i la consecució dels objectius previstos.

Evaluación de los factores de riesgo y los tipos de superficie para el desarrollo de las úlceras por presión en el enfermo crítico = Assessment of risk factors and the types of surface for the development of pressure ulcers on critical ill patients

The main objective of this article is to assess the risk factors and the types of surface for the development of pressure ulcers (PU) on critical ill patients in an Intensive Care Unit (ICU)

Stratégies destinées a optimiser l'utilisation des antibiotiques en réanimation [Strategies targeted at optimising antimicrobial therapy in critically ill patients]

Antibiotics are widely used in critical care and adequate empirical treatments has a significant impact on the outcome of many patients. Most nosocomial infections may be due to multidrug-resistant pathogens and requires empirical borad spectrum coverage before identification of the etiologic agents. This is associated with overuse of antibiotics which contributes to the further increase in multidrug-resistances. In this context, new strategies targeted at antibiotic control, such as guidelines and de-escalation are needed to control this evolution.
