Newman RJ. Muirhead A. Journal of Bone & Joint Surgery - British Volume. 68(4):625-8, 1986 Aug. An unusually wide pneumatic tourniquet has recently become available; we provide a simple formula for its use with a low but effective inflation pressure. A prospective, randomised and controlled trial in 600 lower limb and 150 upper limb operations is reported. The wide tourniquet (12.5 cm) was as effective at low pressure as was a conventional tourniquet (9 cm) inflated to significantly higher pressures. Fewer patients suffered from painful paraesthesiae after operation using the broad, low-pressure tourniquet.
