# Effect of modified indwelling needle insertion techniques in Chinese children: a systematic review and meta-analysis

## TL;DR

This study reviews modified indwelling needle techniques in Chinese children, finding they improve puncture success, indwelling time, and parental satisfaction.

## Contribution

The paper provides a systematic review and meta-analysis of modified indwelling needle techniques in Chinese pediatric populations.

## Key findings

- Modified indwelling needles had a higher puncture success rate than standard needles.
- Indwelling time was significantly prolonged with the modified technique.
- Parental satisfaction was improved with the modified insertion method.

## Abstract

A comprehensive study evaluated the effect of modified indwelling needle technique on puncture success rate and indwelling time in Chinese children.

Compared with ordinary steel needles, indwelling needles have many advantages. The incidence of complications of an indwelling needle is lower than that of an ordinary steel needle. There are many ways to improve it, such as a modified fixation and liquid connection indwelling needle, and many studies have conducted randomized controlled trials.

meta-analysis

Databases including PubMed, Web of Science, CNKI, Wang Fang, CQVIP, Embase were electronically searched for studies on modified indwelling needle insertion techniques from inception to June 20, 2024. Two authors conducted the article search independently. A third author addressed the inconsistencies that arose between the two authors. Keywords were used for retrieval, and Boolean operators were used accordingly.

A total of 18 randomized controlled (RCT) studies were included. The results showed that the puncture success rate, indwelling time and parent satisfaction of the modified indwelling needle insertion technique were better than the control group. Sensitivity analysis was carried out after each study was excluded one by one, and the results showed that pooled sensitivity and specificity had no significant change, indicating that the stability of the meta-analysis, and no publication bias found.

The modified indwelling needle technique showed increased puncture success rate, prolonged indwelling time and improved parental satisfaction compared with the control group.
