Feasibility and Outcomes Associated With the Use of 2.6-Fr Double-Lumen PICCs in Neonates

Peripherally inserted central catheter obstruction in packed red blood cell transfusions in neonates

OBJECTIVES

to estimate incidence and free time of peripherally inserted central catheter obstruction in newborns undergoing red blood cell transfusion in the first 24 hours after the procedure.

METHODS

a longitudinal study, carried out with neonates in Neonatal Intensive Care Unit at a teaching hospital in Paraná, between January and July 2019. The sample consisted of 46 transfusion events performed in neonates through a peripherally inserted central catheter. Analysis performed according to descriptive statistics.

RESULTS

thirty-one catheters were analyzed, inserted in 24 neonates, through which 46 red blood cell transfusions were performed. Most neonates were male, gestational age <32 weeks, weight <1,500 grams, hospitalized mainly for prematurity. Among the 31 catheters, one (3.2%) presented obstruction after transfusion.

CONCLUSIONS

The occurrence of obstructions immediately after transfusion was low and the catheters remained complication free for the next 24 hours.

Obstrução do cateter central de inserção periférica nas transfusões de concentrado de hemácias em neonatos

RESUMO Objetivos: estimar incidência e tempo livre de obstrução do cateter central de inserção periférica em recém-nascidos submetidos à transfusão de hemácias nas primeiras 24 horas após o procedimento. Métodos: estudo longitudinal, realizado com neonatos em Unidade de Terapia Intensiva Neonatal em hospital de ensino do Paraná, entre janeiro e julho de 2019. Amostra foi composta por 46 eventos de transfusões realizadas em neonatos pelo cateter central de inserção periférica. Análise realizada segundo estatística descritiva. Resultados: foram analisados 31 cateteres, inseridos em 24 neonatos, por meio dos quais foram realizadas 46 transfusões de hemácias. A maioria dos neonatos era do sexo masculino, idade gestacional <32 semanas, peso <1.500 gramas, internados principalmente por prematuridade. Dentre os 31 cateteres, um (3,2%) apresentou obstrução após a transfusão. Conclusões: A ocorrência de obstruções imediatamente após transfusão foi baixa e os cateteres permaneceram livres da complicação nas 24h seguintes.

Comparing the use of silicone and polyurethane Peripherally Inserted Central Catheters in newborns: A retrospective study

AIMS AND OBJECTIVES

To compare polyurethane and silicone peripherally inserted central catheters (PICCs) in newborns regarding the success rates of insertion and duration and the reasons for nonelective removal.

BACKGROUND

Previous studies have attempted to identify predictors of PICC complications in newborns, such as lower extremity insertion or femoral catheter insertion, procedures that require 60 minutes or more, duration longer than 30 days and non-central position of the catheter tip. However, there is little evidence on which type of PICC material causes less complications, especially in newborns.

DESIGN

Retrospective cohort, guided by the STROBE tool.

METHODS

We divided the newborns into two groups according to the type of PICC material: polyurethane and silicone. Our sample was composed of 449 PICCs, of which 246 polyurethane PICCs and 203 silicone PICCs, inserted in 294 newborns. Bivariate analysis was performed for data comparison. All statistically significant variables in the bivariate analysis were included in the logistic regression (p ≤ .05).

RESULTS

Of the 449 PICCs that we analysed, the central position of the catheter tip predominated for both types of materials, with a higher prevalence of false passage for the polyurethane group. There was no difference between the average duration. The incidence of nonelective PICC removal was 49.27% for the silicone group, and infiltration/extravasation and rupture were among the reasons for nonelective removal.

CONCLUSION

The overall success rates in the insertion and duration of the PICC were almost identical for both types of material, despite the high incidence of false passage for polyurethane PICCs. Nonelective removals were higher for silicone PICCs, which also had a higher incidence for infiltration/extravasation and rupture.

RELEVANCE TO CLINICAL PRACTICE

Can contribute to the knowledge of the strengths and weaknesses of polyurethane and silicone PICCs, with a view to reduce the incidence of nonelective removals.
