Table saws are associated with more injuries than any other type of woodworking tool. There are no published national epidemiologic studies of table saw-related injuries.
A retrospective analysis was conducted of data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission, 1990 to 2007. Sample weights provided by the National Electronic Injury Surveillance System were used in all analyses to adjust for the inverse probability of case selection and make national projections regarding table saw-related injuries.
An estimated 565,670 (95% confidence interval [CI]: 473,442-657,898) table saw-related injuries were treated in US Emergency Departments from 1990 to 2007. Children (younger than 18 years) were more likely to be injured at school (p < 0.01; relative risk = 68.79; 95% CI: 46.58-101.61), whereas adults were more likely to be injured at home (p < 0.01; relative risk = 2.05; 95% CI: 1.82-2.32). Fingers/thumbs were injured most often (86%; 486,181 of 565,670) and lacerations were the most common type of injury (66%; 373,319 of 565,360). Amputations were associated with 10% (56,848 of 565,360) of the injuries, and most of the amputations involved the finger/thumb (56,817 of 56,848). Eight percent (47,916 of 565,458) of patients were hospitalized.
Most table saw-related injuries result from contact with the saw blade. Passive injury prevention strategies focusing on preventing finger/thumb/hand contact with the blade need to be implemented.
与其他任何类型的木工工具相比,台锯造成的伤害更多。目前尚无已发表的关于台锯相关伤害的全国性流行病学研究。
对美国消费品安全委员会国家电子伤害监测系统1990年至2007年的数据进行回顾性分析。在所有分析中均使用了国家电子伤害监测系统提供的样本权重,以调整病例选择的逆概率,并对台锯相关伤害进行全国性预测。
1990年至2007年期间,估计有565,670例(95%置信区间[CI]:473,442 - 657,898)台锯相关伤害在美国急诊科接受治疗。儿童(18岁以下)在学校受伤的可能性更大(p < 0.01;相对风险 = 68.79;95% CI:46.58 - 101.61),而成年人在家中受伤的可能性更大(p < 0.01;相对风险 = 2.05;95% CI:1.82 - 2.32)。手指/拇指受伤最为常见(86%;565,670例中的486,181例),撕裂伤是最常见的伤害类型(66%;565,360例中的373,319例)。截肢与10%(565,360例中的56,848例)的伤害相关,并且大多数截肢涉及手指/拇指(56,848例中的56,817例)。8%(565,458例中的47,916例)的患者住院治疗。
大多数台锯相关伤害是由于接触锯片所致。需要实施侧重于防止手指/拇指/手部接触锯片的被动伤害预防策略。
