Abstract:
REASONS FOR PERFORMING STUDY: Clinicians frequently place post operative abdominal bandages on horses undergoing laparotomies. Presently, no information exists on the amount of incisional support provided by these bandages. Determination of sub‐bandage pressure provides a means of comparing the ability of different bandages to support incisions. OBJECTIVES: Determination of sub‐bandage pressure over a 24 h period using 3 bandaging techniques. STUDY DESIGN: A randomised, crossover design using 9 healthy horses. METHODS: Horses were randomly assigned to a treatment regimen consisting of placement of 3 abdominal bandage types, namely an elastic bandage (ELA), the CMᵀᴹ Hernia Heal Belt (CM) or a nylon binder (NYL). The sub‐bandage pressures for each bandage were measured with the Picopress® compression‐measuring system at 0, 2, 4, 6, 8, 12, 16, 20 and 24 h after application. RESULTS: No time and treatment interactions were observed, and bandage pressures were maintained within each treatment group over the 24 h period. Mean sub‐bandage pressures were different between all treatment groups (P<0.001) at 39 (95% confidence interval, 36.7–40.5 mmHg), 25 (95% confidence interval, 23.9–27.7 mmHg) and 5 mmHg (95% confidence interval, 4.1–7.8 mmHg) for CM, ELA and NYL bandages, respectively. Horses were more likely to lie down with the CM (P = 0.02) and ELA treatments (P = 0.0002) when compared with the NYL treatment. The ELA bandages were more likely to displace caudally compared with both CM and NYL bandages. CONCLUSIONS: The CM bandage was superior to both ELA and NYL bandages with regard to measured sub‐bandage pressure over the 24 h period. The clinical significance of the differences in sub‐bandage pressure between treatments cannot be determined by this study.
