BackgroundHyperbaric oxygen therapy (HBOT) is used to treat various wound types. However, the possible beneficial and harmful effects of HBOT for acute wounds are unclear.MethodsWe undertook a systematic review to evaluate the effectiveness of HBOT compared to other interventions on wound healing and adverse effects in patients with acute wounds. To detect all available randomized controlled trials (RCTs) we searched five relevant databases up to March 2010. Trial selection, quality assessment, data extraction, and data synthesis were conducted by two of the authors independently.ResultsWe included five trials, totaling 360 patients. These trials, with some methodologic flaws, included different kinds of wound and focused on different outcome parameters, which prohibited meta-analysis. A French trial (n = 36 patients) reported that significantly more crush wounds healed with HBOT than with sham HBOT [relative risk (RR) 1.70, 95% confidence interval (CI) 1.11–2.61]. Moreover, there were significantly fewer additional surgical procedures required with HBOT (RR 1.60, 95% CI 1.03–2.50), and there was significantly less tissue necrosis (RR 1.70, 95% CI 1.11–2.61). In one of two American trials (n = 141) burn wounds healed significantly quicker with HBOT (P < 0.005) than with routine burn care. A British trial (n = 48) compared HBOT with usual care. HBOT resulted in a significantly higher percentage of healthy graft area in split skin grafts (RR 3.50, 95% CI 1.35–9.11). In a Chinese trial (n = 145) HBOT did not significantly improve flap survival in patients with limb skin defects.ConclusionsHBOT, if readily available, appears effective for the management of acute, difficult to heal wounds.
BACKGROUND: Hyperbaric oxygen therapy (HBOT) is used as a treatment for acute wounds (such as those arising from surgery and trauma). However, the effects of HBOT on wound healing are unclear. OBJECTIVES: To determine the effects of HBOT on the healing of acute surgical and traumatic wounds.SEARCH METHODS: We searched the Cochrane Wounds Group Specialised Register (searched 9 August 2013); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 12); Ovid MEDLINE (2010 to July Week 5 2013); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, August 08, 2013); Ovid EMBASE (2010 to 2013 Week 31); EBSCO CINAHL (2010 to 8 August 2013).SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing HBOT with other interventions such as dressings, steroids, or sham HOBT or comparisons between alternative HBOT regimens.DATA COLLECTION AND ANALYSIS: Two review authors conducted selection of trials, risk of bias assessment, data extraction and data synthesis independently. Any disagreements were referred to a third review author. MAIN RESULTS: Four trials involving 229 participants were included. The studies were clinically heterogeneous, which precluded a meta-analysis.One trial (48 participants with burn wounds undergoing split skin grafts) compared HBOT with usual care and reported a significantly higher complete graft survival associated with HBOT (95% healthy graft area risk ratio (RR) 3.50; 95% confidence interval (CI) 1.35 to 9.11). A second trial (10 participants in free flap surgery) reported no significant difference between graft survival (no data available). A third trial (36 participants with crush injuries) reported significantly more wounds healed (RR 1.70; 95% CI 1.11 to 2.61), and significantly less tissue necrosis (RR 0.13; 95% CI 0.02 to 0.90) with HBOT compared to sham HBOT. The fourth trial (135 people undergoing flap grafting) reported no significant differences in complete graft survival with HBOT compared with dexamethasone (RR 1.14; 95% CI 0.95 to 1.38) or heparin (RR 1.21; 95% CI 0.99 to 1.49).Many of the predefined secondary outcomes of the review were not reported. All four trials were at unclear or high risk of bias.AUTHORS' CONCLUSIONS: There is a lack of high quality, valid research evidence regarding the effects of HBOT on wound healing. Whilst two small trials suggested that HBOT may improve the outcomes of skin grafting and trauma, these trials were at risk of bias. Further evaluation by means of high quality RCTs is needed.
Coronary artery bypass grafting is the most frequently performed cardiac surgical procedure. Despite its benefits on survival and quality of life, it is associated with a considerable financial burden on society including sick leave. Our study aimed to explore the barriers that obstruct return to work after coronary artery bypass grafting. We performed a qualitative study with in-depth interviewing of patients 6 months after their surgery. We included ten working patients and interviewed them and their spouses at home. The interviews were transcribed and two investigators independently searched the transcriptions for barriers that had obstructed return to work. Based on the interviews we were able to distinguish four main groups of barriers: 'personal', 'healthcare', 'work' and 'law & regulation.' The personal barriers were subgrouped in affective, physical, cognitive, social and individually determined factors. Conclusion In a qualitative study we showed that personal barriers as well as barriers regarding healthcare, work and law & regulation, were perceived by patients as important factors obstructing return to work after coronary artery bypass grafting. To overcome the identified barriers, the process of return to work could preferably be initiated during the hospital phase, started during cardiac rehabilitation, and coordinated by a case-managing professional.
