Bupivacaine leak past inflated tourniquets during intravenous regional analgesia.
A small leak of bupivacaine was detected in 13 out of 52 cases (25%) during intravenous regional analgesia for the upper limb whilst the tourniquet cuff remained properly inflated. The plasma levels of bupivacaine (range 0.2-0.4 microgram/ml) were well below the toxic range, and no adverse sequelae resulted.
