一种简易负压引流装置在全扩张法耳再造术后的应用.

Objective To explore the clinical efficacy of a simple negative pressure suction drainage device based on a disposable infusion set and a plastic bottle of normal saline in drainage after auricular reconstruction with expanded method. Methods From March 2020 to September 2021, 23 patients received auricular reconstruction with expanded method. A simple negative pressure suction drainage device based on a disposable infusion set and a plastic bottle of normal saline with air drawn was applied for drainage. The efficacy of negative pressure drainage was observed. The postoperative drainage volume, time to extubation, wound healing, infection and flap survival were observed and recorded. Results This simple negative pressure suction drainage device was always unobstructed for all patients. The flap closely fitted the framework. The substructure of auricle was clear. The average drainage volume of the wound was 11 ml daily, and the time to extubation was from 4 to 7 days, with an average of 5 days. All incisions healed by first intension. No necrosis, infection and hematoma of incisions occurred. The blood supply of flap was good. No flap necrosis or framework exposure occurred. Conclusion This device can maintain appropriate negative pressure, which not only ensures the close fit of flap and framework but also does not affect the blood supply of flap. The efficacy of drainage is good and the substructure of reconstructed auricle is clear. [ABSTRACT FROM AUTHOR]
