Effect of Bio-Electro-Magnetic-Energy-Regulation (BEMER) Horse Therapy on Cardiopulmonary Function and Recovery Quality After Isoflurane Anesthesia in 100 Horses Subjected to Pars-Plana Vitrectomy: An Investigator-Blinded Clinical Study.

The use of Bio-Electro-Magnetic-Energy-Regulation (BEMER) therapy during general anesthesia has not previously been reported in horses. This randomized, investigator-blinded, placebo-controlled trial evaluates equine cardiopulmonary function and recovery quality after BEMER therapy application for 15 min in 100 horses during general anesthesia using isoflurane for pars-plana vitrectomy surgery as treatment for recurrent uveitis. Visually identical blankets were used in the two groups (1:1 ratio), one with a functional BEMER module and the other with a placebo module. Arterial blood pressure, blood gas, lactate, and creatine kinase (CK) values were measured at different timepoints, and each timepoint was compared between the groups using paired t-tests. The quality of recovery from anesthesia was assessed by one blinded veterinary surgeon using a 10-category scoring system with scores ranging from 10 (best) to 72 (worst) and compared by an ordinary least squares regression analysis. The placebo group had a significantly better recovery (mean 16.1, standard deviation 7.15) than the BEMER-therapy group (mean 22.4, SD 13.0). Arterial blood pressure and blood lactate were lower in the BEMER-therapy group without reaching statistical significance, while CK and blood gas values were comparable. BEMER-horse therapy showed an effect on the recovery quality of horses undergoing general anesthesia.
