Objectives/Interrogation: Digital tourniquets are used for undemanding hand surgeries due to its simplicity and efficacy. However, the pressure exerted by digital tourniquet has not precisely validated yet. In the present study, we investigated the digital pressures exerted by T-Ring and conventional surgical gloves.

Methods: Thirty volunteers were enrolled in the study. The digital pressures were measured on the dorsal and volar side of the 1st, 2nd, and 5th fingers. Artificial finger model was manufactured using 3-dimensional printer, which was used to measure the serial pressure change over 24 hours (Figure 1 [Fig. 1]).

Results and Conclusions: The pressure exerted by T-Ring was 154.3 ± 54.9 mmHg on the volar side, compared with 224.7 ± 57.7 mmHg on the dorsal side (p<0.05). Similarly, the pressure exerted by the surgical glove was 162.6 ± 61.0 mmHg on the volar side and 228.8 ± 66.0 mmHg on the dorsal side (p< 0.05). There was no difference between T-Ring and surgical gloves (p >0.05). Also, the pressure was not influenced by the finger circumference (Figure 2 [Fig. 2]).

There was no significant decrease in the pressure over 24-hour measurement.

The digital pressure exerted by finger tourniquet was significantly lower on the volar side compared with the dorsal side, regardless of the tourniquet materials or finger circumferences. Tourniquet pressure was maintained for 24 hours.
