Nursing observation on effects of different tourniquet durations of pneumatic tourniquet instrument on postoperative complications in pediatric orthopedic surgery
气压止血仪不同止血时长对儿童骨科术后并发症的护理观察

摘要

目的 探究不同止血时长气压止血仪对儿童骨科术后并发症的影响，总结护理方案，为临床安全使用提供参考。方法 选取2024年1月至2025年12月本院60例骨科四肢手术儿童患者，按止血时长均分两组各30例。对照组采用临床常规止血时长，观察组采用缩短止血时长，两组充气压力、基础护理均保持一致。比较两组肢体肿胀、皮肤压伤及神经感觉异常。结果 观察组患儿术后肢体肿胀、皮肤压伤、神经感觉异常各项并发症发生率均低于对照组；其中肢体肿胀对比χ2=2.960，P=0.085＞0.05，组间差异无统计学意义；皮肤压伤、神经感觉异常组间对比差异存在统计学意义（P＜0.05）。结论 合理把控气压止血仪止血时长，配合优质围术期护理，能有效减少儿童患者术后并发症，减轻疼痛，促进患肢功能恢复，提升手术安全性，适宜临床普及应用。

Abstract

Objective To explore the effects of different tourniquet durations of pneumatic tourniquet on postoperative complications in children undergoing orthopedic surgery, summarize the corresponding nursing protocols, and provide references for its safe clinical application.
Methods A total of 60 children who received limb orthopedic surgery in our hospital from January 2024 to December 2025 were enrolled and equally divided into two groups with 30 cases in each group according to tourniquet duration. The control group was treated with conventional tourniquet duration, while the observation group adopted shortened tourniquet duration. The inflation pressure and basic nursing measures were consistent between the two groups. The incidence of limb swelling, skin pressure injury and abnormal nerve sensation was compared.
Results The incidence rates of postoperative limb swelling, skin pressure injury and abnormal nerve sensation in the observation group were all lower than those in the control group. Among them, for limb swelling, χ2=2.960, P=0.085＞0.05, showing no statistically significant difference between the two groups; the differences in skin pressure injury and abnormal nerve sensation between groups were statistically significant (P＜0.05).
Conclusion   Reasonable control of the tourniquet duration of pneumatic tourniquet combined with high-quality perioperative nursing can effectively reduce postoperative complications, relieve pain, promote the functional recovery of affected limbs and improve surgical safety. It is worthy of clinical promotion and application.
