Evaluation of a stent dressing and abdominal bandage on surgical site infection following emergency equine laparotomy: A randomised controlled trial.

Abstract: Surgical site infection (SSI) is a frequent complication following emergency equine laparotomy, negatively impacting equine welfare, increasing treatment costs and presenting a hospital biosecurity risk. Objective: To determine if a sutured-on stent dressing for incisional protection during anaesthetic recovery reduced SSI following emergency laparotomy. Methods: Randomised controlled trial. Methods: Eligible horses were randomised to a sutured-on stent (intervention) or textile dressing (control) as the primary component of a 3-layer abdominal bandage placed for anaesthetic recovery. Horses were followed up to 90 days postoperatively. Data were analysed according to intention-to-treat principles. Time to SSI (primary outcome) for each group was analysed using a Cox proportional hazard model. Secondary outcomes (SSI and pyrexia during hospitalisation, days hospitalisation and incisional hernia formation at 90 days) were analysed using Chi-squared tests and a univariable logistic regression model (categorical data) or by comparing means between groups (continuous data). Results: Of 352 eligible horses enrolled (167 intervention group, 185 control group), SSI developed in 101 (28.7%) at a mean of 9.7 days (SD 4.6 days). Rate of SSI was not significantly different between groups unadjusted (hazard ratio [HR] 0.83, 95% CI 0.56-1.23, p = 0.4) or adjusted for variables significantly associated with rate of SSI (HR 0.88, 95% CI 0.59-1.30, p = 0.5). There were no significant differences in secondary outcomes between intervention and control groups. Conclusions: Single-centre study evaluating incisional protection from a primary dressing under a secondary adhesive and tertiary fabric abdominal bandage for anaesthetic recovery. Conclusions: Use of a sutured-on stent compared with a textile adhesive dressing as the primary layer of an abdominal bandage for anaesthetic recovery did not reduce the rate of SSI. Further RCT are warranted to investigate efficacy of other interventions on reduction of SSI following emergency laparotomy in horses.

The research article evaluates whether using a sutured-on stent dressing can reduce the occurrence of surgical site infection (SSI) following emergency equine laparotomy, as compared to using a standard textile dressing. The study concluded that there was no significant difference in SSI rates between the two methods.

Research Methodology

  • The research was a randomised controlled trial evaluating the effectiveness of two types of surgical dressings: a sutured-on stent dressing (intervention group) and a standard textile dressing (control group).
  • This was a single-centre study where all horses were undergoing emergency laparotomy. Following surgery, each horse was either treated with the sutured-on stent dressing or the standard textile dressing.
  • A total of 352 horses were included in the trial, with 167 in the intervention group and 185 in the control group.
  • The horses were monitored for up to 90 days post-operatively to observe any occurrence of SSI.
  • The primary outcome measured was time to surgical site infection, while secondary outcomes included SSI and pyrexia during hospitalisation, days of hospitalisation, and incisional hernia formation at 90 days.

Research Findings

  • Overall, SSI developed in 101 out of the 352 horses (28.7%) at an average of 9.7 days post-surgery. The rate of SSI was not significantly different between the two groups.
  • The hazard ratio (HR), which is a measure of the hazard or chance of events occurring in the treatment group as compared to the control group, was 0.83. This means there was no significant advantage of using the sutured-on stent dressing over the standard textile dressing.
  • After accounting for variables that significantly influence the rate of SSI, the adjusted HR was still not significantly different between the two groups (HR 0.88).
  • Secondary outcomes such as SSI and pyrexia during hospitalisation, days of hospitalisation and incisional hernia formation at 90 days also showed no significant differences between the two groups.

Research Conclusions

  • The study found no evidence to suggest that using a sutured-on stent dressing can reduce the rate of SSI following emergency equine laparotomy. The rates of SSI were comparable to those observed in horses treated with a standard textile dressing.
  • The researchers concluded that further randomised controlled trials are needed to investigate other potential interventions that could help reduce the occurrence of SSI following emergency laparotomy in horses.
