Effect of electrical nerve stimulation on healing of ischaemic skin flaps
Abstract
Blood circulation was measured by laser doppler flowmetry in fasciocutaneous flaps of 24 patients who underwent reconstructive surgery for mammary carcinoma. 19 of the 24 patients had clinical signs of deficient circulation in the flaps. 14 patients were treated with electrical nerve stimulation (ENS) and 10 with placebo-ENS. Varying degrees of necrosis developed in 8 of the 10 patients who received placebo stimulation but in none of those treated with ENS. In the 5 patients with good capillary refilling and no signs of stasis or oedema before treatment, only minor increases in blood flow occurred after ENS.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 24 participants or records.
