Pain and paraesthesia produced by silicone ring and pneumatic tourniquets.
Twenty volunteers were recruited to compare a novel, silicone ring tourniquet (the Hemaclear® tourniquet) with a pneumatic tourniquet. After application of the tourniquets, the pain and paraesthesia experienced by the participants was scored at 1 minute, 5 minutes, and 10 minutes. This was repeated with the tourniquets on the forearm. On the upper arm, the silicone ring tourniquet was associated with a significantly lower pain score than the pneumatic tourniquet. The incidence of paraesthesia was also lower with the silicone ring tourniquet. When applied to the forearm, there was no statistically significant difference in pain scores between the two types of tourniquets. However the incidence of paraesthesia was again lower with the silicone ring tourniquet.
