The aim of this study was to evaluate demographics, characteristics, and mechanisms of injuries caused by lawnmowers in children.
Chart review from 1990 to 2010 at a level I pediatric trauma center identified patients younger than 18 years with lawnmower injuries. Demographics and characteristics of the injuries were analyzed by descriptive statistical analysis.
The study identified 88 subjects, with 80% males and 42% of the subjects younger than 5 years. When the lawnmower type was specified, riding lawnmowers caused the majority of injuries (72%). The most common mechanism of injury was related to slipping under lawnmower/being run over (51%). The most common injuries were lacerations (36%), fractures (27%), and amputations (22%); lower extremities were injured more frequently than other body areas (62%). The majority of patients (76%) required hospitalization with a mean length of stay (LOS) of 9.7 days and a mean number of procedures of 4. Complications included 6 infections, 1 tissue necrosis, and 1 death from hemorrhagic shock. Riding-lawnmower injuries were associated with younger children (P < 0.0001). Riding lawnmowers and younger age were associated with longer hospital LOS (P = 0.01, 0.006) and increased number of procedures (P = 0.03, 0.003, respectively).
Lawnmower injuries are still prevalent in children despite national safety recommendations. Injuries seen with riding lawnmowers were associated with younger age, higher number of procedures, longer LOS, and more severe injuries.
本研究旨在评估儿童割草机伤害的人口统计学特征、损伤特点及机制。
对一家一级儿科创伤中心1990年至2010年的病历进行回顾，确定18岁以下因割草机受伤的患者。通过描述性统计分析对损伤的人口统计学特征和特点进行分析。
该研究共纳入88名受试者，其中80%为男性，42%的受试者年龄小于5岁。当明确割草机类型时，乘骑式割草机造成的伤害占大多数（72%）。最常见的致伤机制是在割草机下滑倒/被碾压（51%）。最常见的损伤为撕裂伤（36%）、骨折（27%）和截肢（22%）；下肢受伤比身体其他部位更频繁（62%）。大多数患者（76%）需要住院治疗，平均住院时间（LOS）为9.7天，平均手术次数为4次。并发症包括6例感染、1例组织坏死和1例因失血性休克死亡。乘骑式割草机造成的伤害与年龄较小的儿童相关（P<0.0001）。乘骑式割草机和年龄较小与住院时间延长（P=0.01，0.006）及手术次数增加（分别为P=0.03，0.003）相关。
尽管有国家安全建议，割草机伤害在儿童中仍然很普遍。乘骑式割草机造成的伤害与年龄较小、手术次数较多、住院时间较长及更严重的损伤相关。
