Time-related factors for peripheral intravenous catheterization of critical children

Objective:To verify characteristics related to critical children, the catheter, and the professionals that will influence the time for the success of the puncture Method: Descriptive, prospective, and correlation study, collected with an unique instrument, and a sample consisting of 89 children cared for in the emergency room. Statistical analysis of the association between time and explanatory variables was performed, considering a significance of 5%. Result: The median time for success was 193.4 seconds. Multivariate analysis showed that hypothermic patients (P=0.009) presented prolonged times for success and that the puncture was performed in a shorter time with Vialon (R) 22G catheters (P=0.045). Conclusion: The median time for success was higher than recommended, being influenced by hypothermia and condition of veins the children. The Vialon (R) 22G catheter is the most suitable for puncturing critical patients. Thus, the incorporation of new practices and technologies is necessary for success to occur in less time.
