Hyperbaric oxygen therapy for treating acute surgical and traumatic wounds

Area of Science:

• Wound Healing Research
• Hyperbaric Medicine
• Regenerative Medicine

Background:

• Hyperbaric oxygen therapy (HBOT) is utilized for acute wound treatment, including surgical and traumatic injuries.
• The precise impact of HBOT on wound healing processes remains incompletely understood.

Purpose of the Study:

• To systematically evaluate the effects of hyperbaric oxygen therapy (HBOT) on the healing of acute surgical and traumatic wounds.
• To synthesize findings from randomized controlled trials (RCTs) investigating HBOT for wound healing.

Main Methods:

• Comprehensive literature search of multiple databases (Cochrane, MEDLINE, EMBASE, CINAHL) up to August 2010.
• Inclusion of randomized controlled trials (RCTs) comparing HBOT with control groups or alternative HBOT regimens.
• Independent data extraction and risk of bias assessment by two reviewers, with discrepancies resolved by a third.

Main Results:

• Three heterogeneous trials with 219 participants were included; meta-analysis was not feasible.
• One trial indicated significantly higher graft survival with HBOT for burn wounds (RR 3.50).
• Another trial showed improved wound healing (RR 1.70) and reduced necrosis (RR 0.13) with HBOT for crush injuries, but results for flap grafting were not significant.

Conclusions:

• A significant lack of high-quality evidence exists regarding HBOT's effects on wound healing.
• Preliminary findings from two small, bias-prone trials suggest potential benefits for skin grafting and trauma.
• Further rigorous, high-quality randomized controlled trials (RCTs) are essential to definitively establish HBOT's efficacy in wound healing.
