One purpose of this prospective investigation was to assess the frequency of glove perforations and subsequent blood contact associated with selected obstetric procedures. The second purpose was to assess the relative risk of perforation among different members of the surgical team and determine if time of day or urgency of the procedure affected the frequency of perforation.
Over a 3-month period, obstetric personnel were asked to double glove for all surgical procedures. After surgery, they placed their gloves in plastic bags and noted the type of procedure, time of day, and position on the surgical team. They also indicated whether they were aware of a glove tear and, if so, whether blood or fluid was on their hands. Gloves were tested for injury by two methods: by inflating them with air and subsequently immersing them in water to detect air bubbles and by directly filling them with water to observe for leaks.
A total of 540 glove sets (2160 individual gloves) were examined; 407 sets were from cesarean deliveries, 65 from puerperal tubal ligations, and 68 from vaginal deliveries. Sixty-seven of the sets (12.4%, 95% confidence interval 9.6% to 15.2%) had at least one hole; the total number of holes was 78. Sixty-six holes were in the outer glove only, and 7 were in the inner glove only. In five sets (0.9%, 95% confidence interval 0.5% to 1.3%) there were matching holes in the outer and inner gloves. In two of these cases (0.4%, 95% confidence interval 0.1% to 0.7%) the surgeons noted blood on their hands at the conclusion of the procedure. The difference in frequency of injury in outer versus inner gloves was highly significant (p < 0.005). Forty-six of the 78 holes (59%) were on the thumb or first two fingers of the nondominant hand. Only 2 (3%) of the glove tears were recognized by the surgeon. There was no difference in frequency of glove tears when cesarean sections were classified as urgent versus nonurgent. There also was no difference in frequency of glove tears in procedures performed at night compared with those during the daytime. Surgical nurses had 36% of all glove injuries and were more likely than physicians or medical students to sustain perforations (p < 0.005). Primary surgeons and first assistants were more likely than second assistants to sustain glove injuries (p < 0.05). For primary surgeons and first assistants, level of training did not significantly affect the frequency of glove perforations.
Glove perforations occur in approximately 12% of obstetric surgical procedures. Surgical nurses are at greatest risk for perforation. Double gloving reduces the likelihood of penetrating injury to the inner glove and subsequent risk of blood contact.
这项前瞻性调查的一个目的是评估与特定产科手术相关的手套穿孔及随后血液接触的发生率。第二个目的是评估手术团队不同成员之间穿孔的相对风险,并确定手术时间或手术紧急程度是否会影响穿孔发生率。
在3个月的时间里,要求产科工作人员在所有手术中都戴双层手套。手术后,他们将手套放入塑料袋中,并记录手术类型、时间以及在手术团队中的位置。他们还指出是否意识到手套有撕裂,如果有,手上是否有血液或液体。通过两种方法对手套进行损伤检测:向手套中充气,然后将其浸入水中以检测气泡;直接向手套中注水以观察是否漏水。
共检查了540套手套(2160只单只手套);其中407套来自剖宫产,65套来自产后输卵管结扎术,68套来自阴道分娩。67套手套(12.4%,95%置信区间9.6%至15.2%)至少有一个洞;洞的总数为78个。66个洞仅在外层手套上,7个洞仅在内层手套上。5套手套(0.9%,95%置信区间0.5%至1.3%)外层和内层手套有对应的洞。在其中两例(0.4%,95%置信区间0.1%至0.7%)中,外科医生在手术结束时注意到手上有血。外层手套与内层手套的损伤频率差异非常显著(p<0.005)。78个洞中46个(59%)位于非优势手的拇指或前两个手指上。只有2例(3%)手套撕裂被外科医生发现。剖宫产分为紧急与非紧急时,手套撕裂的频率没有差异。夜间进行的手术与白天进行的手术相比,手套撕裂的频率也没有差异。手术护士发生的手套损伤占所有损伤的36%,比医生或医学生更容易发生穿孔(p<0.005)。主刀医生和第一助手比第二助手更容易发生手套损伤(p<0.05)。对于主刀医生和第一助手,培训水平对手套穿孔频率没有显著影响。
在大约12%的产科手术中会发生手套穿孔。手术护士发生穿孔的风险最高。双层手套可降低内层手套被穿透损伤及随后血液接触的风险。
