Routine neonatal circumcision can be a painful procedure. Although analgesia for circumcision has been studied extensively, there are few studies comparing which surgical technique may be associated with the least pain and discomfort when carried out by pediatric trainees.
We studied two commonly used techniques for circumcision to determine which was associated with less pain and discomfort.
In a randomized, prospective, but not blinded study, newborns were circumcised either by Mogen clamp or by PlastiBell. All received dorsal nerve blocks with lidocaine. Fifty-nine well, term, newborn infants at San Francisco General Hospital were studied from 1997 to 1998. Circumcisions were carried out mostly by interns and residents in family practice and pediatrics. Pain was assessed by measuring duration of the procedure and by a simple behavioral score done sequentially.
Dorsal nerve blocks were judged to be fully effective in over 70% of cases. Neither Mogen nor PlastiBell was associated with greater pain per 3-minute time period, but the PlastiBell technique on average took nearly twice as long as the Mogen procedure (20 vs 12 minutes). We judged that 60% of the infants had pain or discomfort associated with the procedure that was excessive. Residents and interns universally preferred the Mogen technique over the PlastiBell because of the former's simplicity.
During the procedure, Mogen circumcision is associated with less pain and discomfort, takes less time, and is preferred by trainees when compared with the PlastiBell.
常规新生儿包皮环切术可能是一种痛苦的手术。尽管针对包皮环切术的镇痛方法已进行了广泛研究,但很少有研究比较儿科实习生采用哪种手术技术时疼痛和不适可能最少。
我们研究了两种常用的包皮环切术技术,以确定哪种技术引起的疼痛和不适更少。
在一项随机、前瞻性但非盲法的研究中,新生儿分别采用莫根夹或包皮环进行包皮环切术。所有新生儿均接受利多卡因阴茎背神经阻滞。1997年至1998年,对旧金山综合医院的59名健康足月新生儿进行了研究。包皮环切术主要由家庭医学和儿科的实习生及住院医师实施。通过测量手术持续时间和依次进行的简单行为评分来评估疼痛程度。
在超过70%的病例中,阴茎背神经阻滞被判定为完全有效。每3分钟时间段内,莫根夹和包皮环引起的疼痛均无明显差异,但包皮环技术平均所需时间几乎是莫根夹技术的两倍(20分钟对12分钟)。我们判定60%的婴儿手术时伴有过度的疼痛或不适。由于莫根夹技术操作简单,住院医师和实习生普遍更喜欢使用该技术而非包皮环。
在手术过程中,与包皮环相比,莫根夹包皮环切术引起的疼痛和不适更少,所需时间更短,且更受实习生青睐。
