Pneumatic pump reduces leg wound complications in cardiac patients

Area of Science:

• Vascular Surgery
• Postoperative Complication Management
• Medical Device Efficacy

Background:

• Leg wound complications following vein harvest for coronary artery bypass graft (CABG) surgery can lead to significant patient morbidity.
• Pneumatic pressure therapy is established for venous and lymphatic conditions, but its efficacy in the context of leg vein harvest post-CABG was undetermined.

Purpose of the Study:

• To evaluate the effectiveness of sequential pneumatic leg pump therapy in reducing leg wound complications after CABG.
• To assess the impact of this therapy on wound healing, lower limb edema, patient satisfaction, and financial implications.

Main Methods:

• A prospective randomized controlled trial involving 200 patients undergoing CABG.
• The study group received sequential pneumatic leg pump therapy postoperatively, while the control group did not.
• Outcomes measured included wound healing, lower limb edema, patient satisfaction, and hospital stay duration.

Main Results:

• Satisfactory wound healing was observed in 71% of the study group versus 23% in the control group.
• The leg wound infection rate was significantly lower in the study group (3% vs. 15%, p = 0.003).
• Reduced lower limb edema and a 2.6-day shorter hospital stay were noted in patients receiving pneumatic pressure therapy (p < 0.05 and p = 0.003, respectively).

Conclusions:

• Sequential pneumatic leg pump therapy is an effective, inexpensive, and convenient method for reducing leg wound complications post-CABG.
• The therapy demonstrably improves wound healing, decreases infection rates, and shortens hospital stays.
• This intervention offers a valuable addition to postoperative care following vein harvest for CABG procedures.
