081 ELASTIC EXSANGUINATION RING AS AN ALTERNATIVE TO THE PNEUMATIC CUFF IN ORTHOPAEDIC ONCOLOGY

Abstract

Bloodless field in limb musculoskeletal tumours’ surgery has great value as it facilitates resection and reconstructions without excessive bleeding.

40 large bone or soft tissue tumors located in upper (n=4) and lower limbs (n=36) were resected and reconstructed in bloodless surgical field achieved by a new device, an elastic silicone ring (S-Mart, OHK Medical Device). Proper size of it is chosen between items of different diameter, length and elasticity depending on their measurements and BP. Our goal was safe and sufficient blood pressure for bloodless operation. In tumours, esh-mark and any pressure on the mass results in microscopic spread. We rolled the ring along the limb, starting from digits and exsanguinated the limb raising it above the tumour to avoid crushing it. If tumours extend too proximally to hip and shoulder we cannot use tourniquet because cuffs are wide enough to allow proximal extension of the incision. The elastic ring we used, is too narrow (Φ< 20cm) and proved of utmost importance in large, bleeding growths helping tumour elimination and limb salvaging. The ring was applied from 18–120 minutes created completely bloodless surgical field thus facilitating and speeding up the operation. The time needed for application was shorter than for pneumatic tourniquet (< 10sec). After removing the elastic ring we noticed neither BP drop nor tumour spread or complications of skin and neurovascular elements pressure.

Thus we conclude that limb ischaemia achieved with special elastic rings have benefits and may be considered as safe in oncological surgery.
