The correlation between weight gain and PICC tip shift in the very low birth weight infants

The relationship between the PICC tip position and weight gain, length growth of premature infants under ultrasonography: a correlation analysis study

Objective

This study aimed to analyze the correlation between PICC tip position and weight/length changes in preterm infants in different positions using ultrasonography.

Methods

The study is a prospective before and after self-control clinical trial. The study analyzed the distance between the PICC tip and the entrance of the heart under ultrasonography for premature infants who underwent PICC insertion. The infants were positioned and tracked weekly, and their weight and length were recorded. The Spearman rank correlation test was used to analyze the relationship between the displacement distance of the PICC tip under ultrasonography in different positions and weight/length changes.

Results

A total of 202 premature infants were included in the study, and 100% of them experienced changes in the PICC tip position. During the first week, 134 (66.33%) cases in a flexed position and 153 (75.74%) cases in a straight position showed displacement of the catheter toward the heart. The displacement distance of the tip during catheter retention was significantly correlated with weight change (r_s = 0.681/0.661, P < 0.05) and length change (r_s = 0.629/0.617, P < 0.05). In the third and fifth weeks, weight increased by 451 ± 178 and 750 (715-975) g, length increased by 1.50 (1.00-2.12) and 3.00 (2.00-3.70) cm, the catheter moved 1.27 ± 0.89 and 2.23 ± 0.95 cm, respectively, in a flexed position.

Conclusion

The PICC tip position in preterm infants is influenced by weight and length changes. It is crucial to use ultrasonography to track and locate the catheter within the first week of placement and to increase the frequency of catheter localization starting from the third and fifth weeks. The flexed position is recommended during catheter localization.

Effect of femoral PICC line insertion in neonates with digestive tract disease

OBJECTIVE

To investigate the clinical effects of various catheterization pathways to guide vein selection in neonates.

METHODS

In this retrospective study, a total of 40 newborns admitted to the Neonatal Surgery Department of Nanjing Children's Hospital who were hospitalized for gastrointestinal diseases and required intravenous nutrition from March 2020 to December 2020 were included. The patients were divided into a control group (basilic vein and superficial temporal vein) and an observation group (femoral vein of the lower extremity) according to the puncture site of the vein. Blood loss, incidences of phlebitis, incidences of catheter dislocation, frequency of dressing replacement, catheter-related blood infection rate, the satisfaction of family members and bacteriological test results of the catheter tip (1-2 cm) after catheter removal were compared between the two groups.

RESULTS

The incidence of phlebitis and catheter dislocation was lower while the satisfaction rate of family members was higher in the observation group as compared with those in the control group (all P<0.05).

CONCLUSIONS

PICC insertion through the femoral vein can effectively reduce catheter-related complications, shorten the days of hospitalization and improve the comfort of children and the satisfaction of their families.

Effects of Peripherally Inserted Central Catheter (PICC) Catheterization Nursing on Bloodstream Infection in Peripheral Central Venous Catheters in Lung Cancer: A Single-Center, Retrospective Study

Background. Peripherally inserted central catheter (PICC), as one of the important intravenous routes for the rescue and treatment of critically ill patients, has been widely used in the fluid resuscitation of critically ill patients in intensive care. In particular, PICC can be widely used in the treatment of cancer patients. With the wide application of peripheral central venous catheterization, the clinical findings of bloodstream infection complications caused by PICC have gradually attracted the attention of doctors and patients. Aims. To investigate the effect of specialized placement and PICC placement care on patients with lung cancer who underwent PICC puncture. Patients were selected and divided into a comparison group and an observation group of 40 patients each according to the randomized residual grouping method. In the comparison group, routine PICC placement and catheter maintenance were performed, while the observation group was provided with specialized placement and PICC placement care. The differences in immune and tumor marker levels and nursing compliance between the two groups were observed and compared before and after nursing care. Results. There was no significant difference in the comparison of tumor marker levels between the two groups of patients before care, while the levels of CYFRA21-1, CA125, and VGEF in the observation group were significantly lower than those in the comparison group after care, and this difference was statistically significant ( $P<0.05$ ). There was no statistically significant difference in the comparison of immune levels between the two groups before care ( $P>0.05$ ), while the comparison of CD4+, CD3+, and CD4+/CD8+ after care was significantly different and higher in the observation group than in the comparison group, and the comparison was statistically significant ( $P<0.05$ ). The compliance rate of 93.8% in the observation group was significantly higher than that of 77.9% in the comparison group, and this difference was statistically significant for comparison ( $P<0.05$ ). Conclusion. PICC placement care is more effective in patients with lung cancer and performing PICC puncture, significantly improves patients’ immune and tumor marker levels, improves patients’ negative emotions, reduces disease uncertainty, and improves nursing compliance.
