'''Clinical bottom line:'''

1. Some weak evidence that suction can be maintained safely for negative pressure dressings during HBOT 2. Authors used suction equipment available within the chamber as commercial NPWD suction was not licensed for use in the chamber.

'''Three-part Clinical Question:'''For patients with chronic wounds being treated with hyperbaric oxygen, can negative pressure wound dressings being maintained during therapy, compared to stopped for therapy, lead to safe and effective wound management? '''Search Terms:''' Chronic wounds, negative pressure wound dressings, pain

'''The Study:'''Single-blinded concealed randomised controlled trial with intention-to-treat. '''The Study Patients:''' Patients with diabetic ulcers on the lower leg for whom both HBOT and negative pressure wound dressings (NPWD) had been prescribed. '''Control group''' (N = 6; 6 analysed): NPWD suspended during a single HBOT session '''Experimental group''' (N = 6; 6 analysed): NPWD maintained using internal suction during a single HBOT session.

'''Comments:''' 1. Very small crossover trial with six patients and two treatments each. 2. Authors stated no difference in pain scores during and after treatment but have not given any of the numerical results. 3. Assessors were blinded.
