A neuropathic-like pain syndrome was produced in rats following prolonged hindpaw ischemia and reperfusion, creating an animal model of complex regional pain syndrome-Type I (CRPS-I; reflex sympathetic dystrophy) that we call chronic post-ischemia pain (CPIP). The method involves placing a tourniquet (a tight fitting O-ring) on one hindlimb of an anesthetized rat just proximal to the ankle join...

[Purpose] This study compared the analgesic effects of transcutaneous electrical nerve stimulation (TENS) and interferential currents (IFC) on induced ischemic pain in healthy volunteers. [Subjects] The subjects were 36 volunteers (18 male, 18 female) without known pathology that could cause pain. Their mean age was 24.5±2.2 years. [Methods] A single-blind and parallel-group method was used. Su...

The blocking of the posterior tibial, sural, saphenous, superficial peroneal, and the deep peroneal nerves with possible alternative approaches is discussed. Digital blocks, Mayo blocks, and intravenous regional anesthesia are also discussed. The placement of the tourniquet above the ankle but below the calf muscles will avoid deep muscle pain. Lidocaine and bupivacaine cause vasodilatation in ...

OBJECTIVE Baroreceptor activation has been shown to reduce pain, and the accumulation of such pain reduction has been implicated in the operant learning (under certain circumstances) of hypertension. The current study is an examination of differences in the pain dampening effects of baroreceptor activity in patients with symptomatic and asymptomatic myocardial ischaemia. The objective was to de...

The relative importance of ischaemic and direct mechanical injury to nerves compressed by a tourniquet, in the pathogenesis of tourniquet paralysis in man has not been established. To investigate this question, conduction in ulnar or median nerve fibres has been measured in healthy subjects both at the level of the pneumatic tourniquet and distal to the tourniquet. Measurement was prior to, for...

The literature indicates that tourniquet-induced neurological injuries are relatively common and frequently occur at a subclinical level. In order to evaluate the pressure transmitted to the major peripheral nerves of the arm by an externally applied pneumatic tourniquet, a fully implantable biomedical pressure transducer was placed adjacent the radial, median and ulnar nerves in six cadaver up...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013200942 DESCRIPTION A 32-year-old woman presented with a 1-year history of severe paroxysmal pain, point tenderness and sensitivity to cold in her left thumb. On examination, a faint bluish lesion in the middle, radial subungual region of the left th...

Tourniquet-use has been described in litera- ture as a surgical factor leading to increased post-operative hidden blood loss total knee arthroplasty (TKA). The hypothesis for this retro- spective study was that low-pressure tourniquet TKA would offer the benefits of surgery without potential negative effects on late after procedure. Therefore, evaluated (TBL) and (HBL) with or tourniquet. We re...
