There is much dogma that has been passed on from generation to generation on how we should manage lacerations in the ED. In this Journal Jam podcast Anton and Justin welcome special guest Dr. Haley Cochrane. We dive deep into the evidence for timing of closure and infection rate, fluid choice, volume and pressure of irrigation of lacerations, glove type and infection rate, how eversion of wound edges effects cosmetic outcomes and much more. You might be surprised to discover that the evidence for many things we do for lacerations that are considered “standard of care”, is either weak or non-existent. But do not fret – we deliver practical bottom line practical recommendations to help improve outcomes, save time and decrease resource utilization…

How late is too late for suturing lacerations? The timing of closure of lacerations

Take home points on timing of closure of lacerations:

  • Whenever possible, close lacerations sooner rather than later as they are likely to heal faster with early closure.
  • It is unclear from the literature if delayed closure increases infection rates or not.
  • The most important management piece when it comes to delayed presentations for lacerations is counseling the patient who presents late after a laceration about what to expect with regards to healing, and taking into account cosmesis and patient preference in deciding whether or not to close the laceration.
  • The usual instructions to return if signs of infection apply regardless of when the laceration is closed.

Wound irrigation: Does it improve outcomes? Fluid type, volume and pressure

Take home points on wound irrigation

  • The evidence for any real benefit of wound irrigation for lacerations is not clear.
  • For visibly dirty wounds and those that were caused by a dirty implement (especially in an immunocompromised patient), irrigation makes intuitive sense and seems reasonable.
  • Irrigation should not be a priority in clean-appearing wounds caused by a clean implement.
  • There is no clinical evidence at all to guide us on the volume of irrigation fluid that is sufficient or necessary.
  • Data on pressure is severely limited and mixed with only one positive trial.
  • Based on a Cochrane Review and double blind RCT it appears that tap water irrigation of lacerations is associated with a lower infection rate compared to saline.
  • There is a suggestion from older literature from the 1980’s that wound irrigation with povidone-iodine decreases infection rates after skin laceration, while there is no data on chlorhexidine; it seems reasonable to irrigate visibly highly contaminated dirty wounds or wounds caused by a very dirty implement (especially in an immunocompromised patient) with povidone-iodine solution.

Are sterile gloves necessary for laceration repair?

  • About 50% of the “non-sterile” clean gloves taken from a box in an ICU were sterile, and when bacteria did grow from the gloves, none of them were significant pathogens in high enough quantity to be of concern for infection.
  • Two RCTs comparing sterile gloves and “non-sterile” clean boxed gloves found no significant difference in the infection rate – 6.1-6.8 % with sterile gloves and 4.4-5.7% with clean gloves.
  • Sterile gloves may be preferred for procedures that require a high degree of tactile response.
  • Out-of-the-box clean gloves are acceptable for the majority of laceration repairs; consider sterile gloves for immunocompromised patients.

Is eversion of skin edges necessary in skin laceration repair?

  • There is only one clinical trial in the dermatology literature comparing eversion of lacerated skin edges during repair to flat closure with simple interrupted sutures and there was no difference in cosmetic outcome at 3-6 months
  • Perhaps more important than skin eversion is minimizing the tension on wound edges by utilizing deep sutures or mattress sutures although there is no data to support this notion
