Postoperative Hyperbaric Oxygen Treatments to Reduce Complications in Diabetic Patients Undergoing Vascular Surgery

Phase 2

Withdrawn

• Conditions: Arterial Occlusive Disease; Diabetes; Peripheral Arterial Disease
• Interventions: Procedure: Sham HBO; Procedure: Hyperbaric Oxygen treatment (HBO)

• Registration Number: NCT01002209
• Lead Sponsor: Karolinska Institutet

Brief Summary

This trial aims to evaluate if hyperbaric oxygen treatment (HBO) given postoperatively is effective in reducing healing time and wound complications after lower extremity bypass surgery in patients with diabetes.

Hypothesis: Postoperative HBO treatment is effective in reducing complications in patients with diabetes undergoing peripheral vascular surgery

Primary Outcome Measures

Name	Time	Method
Time to complete healing of operative wounds	7-365 days

Secondary Outcome Measures

Name	Time	Method
Tissue perfusion and oxygenation on dorsum of foot on operated extremity as assessed by Transcutaneous oximetry during normobaric air breathing and after 6 min normobaric 100% oxygen challenge	day 3-5, 7 and 14, 28, 365 (plus minus 3 days)
The severity of wound infection defined as by ASEPSIS score: 0-10= satisfactory healing 11-20= disturbed healing 21-30= minor wound infection 31-40= moderate wound infection >40= severe wound infection.	highest score up to 30 days (plus minus 3 days)
SF-36 score	7, 14, 28, 365 days (plus minus 3 days)
Major amputation or death. This will be assessed as "amputation-free survival". A major amputation is defined as any ipsilateral amputation through or above the ankle.	0-365 days
Number of wound infections at 7 days assessed by ASEPSIS score. A score over 20 will be considered as a wound infection.	7 days (plus minus 3 days)
Number of wound infections at 30 days assessed by ASEPSIS score. A score over 20 will be considered as a wound infection.	30 days (plus minus 3 days)
A combination of any wound infection and/or unhealed wounds at 30 days (combined endpoint).	30 days (plus minus 3 days)
HBO complications (confinement anxiety, barotrauma, oxygen convulsions)	During HBO treatment up to day 6
