Comparison of the effect on blood flow of two intradermal suture patterns in feline skin: A within animal randomized controlled trial
🔍 Key Findings
- A within-animal randomized controlled trial was performed in 32 adult cats undergoing ovariohysterectomy, allowing direct comparison of two intradermal skin-closure patterns in the same incision.
- Each 4-cm ventral midline incision was divided into cranial and caudal halves, randomly assigned to either a modified Allgower-Donati (mAD) intradermal pattern or a standard intradermal horizontal mattress pattern (SP).
- The modified Allgower-Donati pattern significantly increased wound-edge perfusion, whereas the standard intradermal horizontal mattress pattern decreased perfusion.
- Mean perfusion change was +59.7 ± 124.1 BPU with mAD versus −20.2 ± 119.9 BPU with SP (p < .01), demonstrating improved acute microcirculation with the mAD technique.
- Relative perfusion increased by 115.3% with mAD but decreased by 24.1% with SP, reinforcing the perfusion advantage of the modified pattern.
- The critical technical difference was suture bite orientation: mAD placed dermal bites perpendicular (90°) to the incision, while the standard pattern placed bites parallel and close to the wound edge.
- Both techniques used buried continuous intradermal closure with 4-0 poliglecaprone, maintaining the cosmetic and patient-comfort advantages of intradermal suturing.
- No incisional complications were reported within 30 days, although follow-up relied on re-presentation rather than scheduled examination, limiting detection of minor complications.
