Hyperbaric oxygen therapy is a recognised modality of treatment with applications in plastic surgery. This modality of treatment works by providing higher oxygen delivery to tissues. The benefits of this modality of treatment in free flap surgery were studied.
A randomised prospective study was done. Ten patients undergoing free tissue transfer by microvascular technique were studied. These patients were randomised into two groups. In Group 1 the patients were subjected to hyperbaric oxygen therapy postoperatively for seven days. Group 2 served as the control group. Patients in this group were not subjected to hyperbaric oxygen therapy. Patients were evaluated up to 14 days postoperatively. The flaps were evaluated for any flap loss, presence of venous congestion in the flap, flap oedema, and completeness of healing at the flap site.
No significant difference was found in terms of flap survival, time to resolution of venous congestion, resolution of oedema, and period of postoperative recovery.
Routine use of hyperbaric oxygen therapy does not result in better survival of free flaps.
高压氧疗法是一种在整形外科中得到认可的治疗方式。这种治疗方式通过向组织提供更高的氧气输送量来发挥作用。本研究探讨了这种治疗方式在游离皮瓣手术中的益处。
进行了一项随机前瞻性研究。研究了10例接受微血管技术游离组织移植的患者。这些患者被随机分为两组。第1组患者术后接受7天的高压氧治疗。第2组作为对照组。该组患者未接受高压氧治疗。对患者进行术后14天的评估。评估皮瓣是否有皮瓣丢失、皮瓣静脉淤血情况、皮瓣水肿以及皮瓣部位愈合的完整性。
在皮瓣存活、静脉淤血消退时间、水肿消退情况及术后恢复时间方面未发现显著差异。
常规使用高压氧疗法并不会使游离皮瓣的存活率更高。
