Valuation of the effectiveness of the nitrous oxide administration to the paediatric patient during channelling a peripheral venous

Objective: To valuate if the administration of nitrous oxide (Kalinox ) during the technique of channelling a peripheral venous level decreases pain, improves the child′s behavior and facilitates the realization of the technique for the nurse. Experimental, randomized clinical trial. Population: children between 6-12 years old with an indication of peripheral venous channeling and medical approbation for administration of Kalinox to the Pediatric ICU unit of the Hospital in Toledo. Sample: 54 subjects in each group (alpha error of 0.05, with a study power of 90% and expecting a mean effect d/s = 0.5 for reducing pain in the experimental group. Main variables: the administration of nitrous oxide (independent variable) and level of pain, motor behavior, degree of difficulty in performing the technique, and complications (dependent variables), besides, sociodemographic and clinical variables will be measured. It was used differents validated scales (Oucher, VAS y Frankl) and one performed by us. Data will be analyze by SPSS software programme.
