Introduction: Lumbar puncture (LP) is a commonly performed procedure in paediatrics. Performing this technique properly can avoid the most common associated complications., Objective: To assess whether paediatricians and paediatric residents in Spain follow current recommendations for the LP technique., Material and Methods: A cross-sectional study was conducted by sending a questionnaire by mail through the Spanish Society of Paediatric Emergencies, collecting demographic information and responses to multiple choice questions about LP technique., Results: A total of 206 questionnaires were analysed, of which 143 (69.5%) were answered by paediatricians, and 63 (30.5%) by paediatric residents. The majority (128; 62.1%) of physicians did not allow parents to be present during LP, 198 (96.1%) routinely use analgesia and sedation; 84 (42%) only used local anaesthesia. The majority of respondents used standard Quincke needles (126; 62.7%). The bevel was correctly positioned when puncturing the dura mater by 22 residents (36.1%) and 21 paediatricians (15.1%), a variation that was statistically significant (P=.001). For neonatal lumbar punctures, 63 paediatricians (46%) and 19 paediatric residents used a butterfly needle which did not contain a stylet, and this difference was also statistically significant (P=.035). Of those surveyed, 190 (92.2%) re-inserted the stylet when re-orientating the needle, and 186 (93%) re-oriented this when removing it. The recommendation of bed rest was made by 195 (94.7%) physicians., Conclusions: The majority of paediatricians orient the bevel wrongly when inserting the needle during LP, and still use "butterfly" needles in newborns, despite warnings to the contrary. Paediatric residents and less experienced paediatricians follow the recommendations more frequently., (Copyright © 2011 Asociación Española de Pediatría. Published by Elsevier Espana.

Introduction: Bladder catheterization (BC) is frequently performed to diagnose urinary tract infection (UTI) (the most common serious bacterial infection among young children). The purposes of this study were to evaluate performance and complications of BC to obtain a urine specimen., Material and Methods: This was a prospective study conducted in an urban children's hospital on patients who had a urine specimen obtained in the emergency department (ED) by BC between November 1, 2009 and December 15, 2009. Epidemiological data and the medical reasons why the BC was performed were reviewed. Finally, to determine the complications we contacted the family by telephone at least one month after the BC., Results: A total of 126 BC were performed in 124 patients, 45 males (35.7%) and 81 female (64.3%). A urine sample was obtained in all cases. The median age was 7 months (5 days-35 months). Of the 126 urine cultures collected, 34 were positive (26.98%) and 1 was considered contaminated (0.8%). Escherichia coli was the most common pathogen (27, 79.41%). Fever (76.2%) was the main reason why BC was performed in children. Of the 116 patients contacted by telephone, only 5 mentioned complications: genital pain (3), unconfirmed hematuria (1) and UTI 12 days after (1)., Conclusions: BC performed in ED to obtain a urine sample in non toilet-trained children is effective and safe. BC is an invasive method which needs to be quality controlled., (Copyright © 2011 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.)
