Round-tipped blunt needle (BN) may decrease the risk of needlestick injuries and hand contamination. We prospectively determined the incidence of glove perforations in emergency abdominal procedures and the efficacy of BN in increasing the safety for surgeons.
Two hundred patients were randomized to undergo closure of the abdominal fascia using sharp needle (SN) or BN. Gloves were tested at the end of the procedure.
Surgeons had 14 needlestick injuries and 76 perforations recorded in 69 pair of gloves. Sharp needles were responsible for all injuries and 58 (76%) perforations (P < 0.00004 and P < 0.00001, respectively). This difference was still higher when considering the perforations related to the abdominal fascia closure (BN 7% versus SN 50%; P < 0.0006).
The risk of glove perforation is sevenfold greater if SN are used. Blunt needles reduce sharp injuries and improve safety for surgeons.
圆头钝针（BN）可能会降低针刺伤和手部污染的风险。我们前瞻性地确定了急诊腹部手术中手套穿孔的发生率以及钝针在提高外科医生安全性方面的有效性。
200例患者被随机分为使用锐针（SN）或钝针进行腹部筋膜缝合。手术结束时对手套进行检测。
在69副手套中记录到外科医生发生了14次针刺伤和76次穿孔。所有损伤和58次（76%）穿孔均由锐针导致（分别为P < 0.00004和P < 0.00001）。在考虑与腹部筋膜缝合相关的穿孔时，这种差异仍然更大（钝针7% 对比锐针50%；P < 0.0006）。
如果使用锐针，手套穿孔的风险会高出7倍。钝针可减少锐器伤并提高外科医生的安全性。
