Laceration Management.

BACKGROUND: Traumatic lacerations to the skin represent a fairly common reason for seeking emergency department care. Although the incidence of lacerations has decreased over the past decades, traumatic cutaneous lacerations remain a common reason for patients to seek emergency department care. OBJECTIVE: Innovations in laceration management have the potential to improve patient experience with this common presentation. DISCUSSION: Studies have confirmed that delays in wound closure rarely confer increased rates of infection, although comorbidities such as diabetes, chronic renal failure, obesity, human immunodeficiency virus, smoking, and cancer should be considered. Antibiotics should be reserved for high-risk wounds, such as those with comorbidities, gross contamination, involvement of deeper structures, stellate wounds, and selected bite wounds. Topical anesthetics, which are painless to apply, have a role in select populations. In most studies, absorbable sutures perform similarly to nonabsorbable sutures and do not require revisit for removal. Novel atraumatic closure devices and expanded use of tissue adhesives for wounds under tension further erode the primacy of regular sutures in wound closure. Maintaining a moist wound environment with occlusive dressings is more important than previously thought. Most topical wound agents are of limited benefit. CONCLUSIONS: Recent innovations in wound closure are allowing emergency physicians to shift toward painless, atraumatic, and rapid closure of lacerations.

A randomized trial comparing metallic and absorbable staples for closure of a Pfannenstiel incision for cesarean delivery.

OBJECTIVE: The purpose of the study is to compare postoperative pain, cost, speed of closure, and patient satisfaction of Pfannenstiel skin incisions closed with traditional metallic staples vs absorbable staples after cesarean delivery. It is hypothesized that incisions closed with absorbable staples will cause less postoperative pain than traditional metallic staples. STUDY DESIGN: A randomized, controlled trial was conducted from July 2010 through May 2011. Patients undergoing a scheduled cesarean delivery via a Pfannenstiel skin incision were recruited. Patients were randomized into the control group (metallic staples) or the experimental group (absorbable staples). The postpartum nurse and patient were blinded to the type of staples. Postoperative pain was assessed using a visual analog scale on both postoperative day 1 and day of discharge, and the total dose of oral narcotics taken during the postoperative period was assessed. RESULTS: In all, 100 patients enrolled in the study: 50 in each group. Based on visual analog scale scores, there were no significant differences between the 2 groups on postoperative day 1 or day of discharge. There were no significant differences in the total dose of oral narcotics taken or in wound complication rates. The time for skin closure was significantly different: 3.5 ± 1.7 for absorbable and 1.39 ± 0.7 minutes for metallic staples (P < .0001). The calculated cost of each device, including placement and removal, was $285.60 for the absorbable and $150.79 for the metallic staples. CONCLUSION: Postoperative pain is comparable for both devices. The absorbable staple skin closure time, and therefore cost, is significantly greater than for metallic staples.

The Prospects for Biodegradable Zinc in Wound Closure Applications.

Zinc is identified as a promising biodegradable metal along with magnesium and iron. In the last 5 years, considerable progress is made on understanding the mechanical properties, biodegradability, and biocompatibility of zinc and its alloys. A majority of these studies have focused on using zinc for absorbable cardiovascular and orthopedic device applications. However, it is likely that zinc is also suitable for other biomedical applications. In this work, the prospects for zinc in the fabrication of wound closure devices such as absorbable sutures, staples, and surgical tacks are critically assessed, with the aim of inspiring future research on biodegradable Zn for this medical application.

Incidence of wound complications in cesarean deliveries following closure with absorbable subcuticular staples versus conventional skin closure techniques.

OBJECTIVE: To determine if there is a significant difference in composite wound complications among traditional closure techniques versus absorbable subcuticular staple closure. STUDY DESIGN: This study is a retrospective cohort study of cesarean sections performed from January through September of 2014. Composite wound complications included surgical site infection, separation, and fluid collection. Medical records were reviewed and data including the patient demographics, comorbidities, closure type and wound complications were recorded. Patients with incomplete data were excluded. Data were analyzed with ANOVA or Fisher exact test, according to data type. RESULTS: Of the 186 patients identified, 176 patients were included in the data analysis (n=83 suture, n=49 traditional staple, n=44 the absorbable subcuticular staple). The groups were similar in all demographic categories; labor prior to delivery, estimated blood loss, and medical and pregnancy related comorbidities. The overall incidence of wound complications at our institution during this study was 5.7%. The incidence of complications among the suture and subcuticular staple closure was not significantly different (3.6% versus 0%, p=0.3), however there were significantly less complications in the suture and subcuticular staple closure groups when compared to traditional staple closure (14.3%) (p=0.03 and p=0.01, respectively). CONCLUSION: Herein, we report a decreased incidence of composite wound complications with subcuticular staple closure versus traditional staple closure in patients undergoing cesarean section. Absorbable subcuticular staple closure represents a convenient, safe and cost-effective closure technique.
