This research describes a comparative study using convenience sampling on management of intravenous lines in Maternity Neonatal Intensive Care Unit (MNICU), HKL. Questionnaires were answered by nurses and the techniques of anchoring, splinting and maintaining of intravenous lines by nurses in MNICU were observed by the researchers. The study showed that nurses with less than two years experience working in MNICU had significantly less knowledge and skills in the management of intravenous lines and are likely to encounter more difficulties and complications, compared to nurses with more experience.
