To determine the effect of splint on the dwell time of peripheral intravenous cannula in neonates.
Level II Neonatal Intensive Care Unit (NICU).
Consecutive babies with presumed need of peripheral intravenous access of at least 24 h.
Enrolled subjects were randomized to "splint" or "splint-less" group. Insertion site was cleaned with Isopropyl alcohol and 2% Chlorhexidine and peripheral intravenous catheter was inserted under strict asepsis. Insertion sites was examined regularly for occurrence of complication which necessitated removal of the catheter.
Out of 159 neonates, 80 were allotted to splint group and the rest to splint-less group. Mean dwell time of intravenous line in splint group was 27.68 ± 13.03 h which was significantly less than in splint-less group (32.87 ± 15.79 h, mean difference: 5.11 h, value: 0.03). Subgroup analysis in preterms showed mean dwell time of 28.54 ± 14.86 h in splint group which was less than that of splint-less group (35.10 ± 16.24 h) ( value: 0.03). No such difference was noted in the term neonates. Subgroup analysis for catheters put across joints does not show difference in mean dwell times between splint and splint-less groups. Multivariate regression analysis did not identify any variable which independently affected the outcome.
Use of splint does not prolong the dwell time of the catheter and is probably harmful in some neonates.
确定夹板对新生儿外周静脉留置时间的影响。
二级新生儿重症监护病房（NICU）。
连续需要至少 24 小时外周静脉通路的新生儿。
将纳入的患儿随机分为“夹板”或“无夹板”组。用异丙醇和 2%洗必泰清洁插入部位，严格无菌操作插入外周静脉导管。定期检查插入部位是否发生并发症，需要拔除导管。
在 159 名新生儿中，80 名被分配到夹板组，其余被分配到无夹板组。夹板组的静脉留置时间平均为 27.68±13.03 小时，明显短于无夹板组（32.87±15.79 小时，平均差异：5.11 小时， 值：0.03）。早产儿亚组分析显示，夹板组的平均留置时间为 28.54±14.86 小时，短于无夹板组（35.10±16.24 小时）（ 值：0.03）。足月新生儿则没有这种差异。关节处放置导管的亚组分析显示，夹板和无夹板组的平均留置时间无差异。多变量回归分析未发现任何独立影响结果的变量。
夹板的使用不会延长导管的留置时间，而且在某些新生儿中可能是有害的。
