Abstract
Aim: To evaluate the effect of 2 catheter materials of peripheral intravenous (PIV) cannulae—polyurethane (PUR) versus polytetrafluoroethylene (PTFE)—on the functional longevity of PIV cannulation in newborns
Materials and Methods: This was a single-center, randomized controlled trial carried out in a level 3 NICU of a tertiary care teaching hospital. It included term and preterm newborns (who were born > 28 wk of gestation; N = 44) who were admitted to the NICU and were anticipated to require PIV cannulation for intravenous (IV) infusion for at least 48 hours. The newborns were randomized to receive cannulation with either the PUR cannula or the PTFE cannula.
The primary outcome measure was functional duration of the IV cannulation, which was measured as the interval between the time of insertion of the cannula to the development of a predefined sign for removal (occurrence of extravasations, blockage, inflammation, or leakage or the PIV line was no longer required).
Results: In the 44 newborns who were enrolled into the study, 64 PIV cannulations were performed (some newborns had more than one PIV cannulations). The baseline characteristics of the 2 study groups were similar. The mean functional longevity of the PIV cannulation was similar in both the groups: the PUR group, 65.59 ± 46.01 hours and the PTFE group, 55.92 ± 32.84 hours (P = .34). The reasons for removal of the PIV cannula were similar in both the groups.
Conclusion: There was no significant difference in the functional longevity of the PIV cannulation between the 2 catheter materials studied (PUR and PTFE).
