Tourniquet Safety: Mechanisms and Prevention of Injuries

To improve tourniquet safety for patients, it is important to know the mechanisms and prevention of tourniquet injuries. Surgical Tourniquet Safety It is reliably estimated that pneumatic tourniquets are used in more than one million surgical procedures annually in North America. The potential for injury is significant, although the use of lower, personalized tourniquet pressure [...]

Tourniquet Cuff Technology

Tourniquet Cuff Technology: What is the purpose of a tourniquet cuff? The purpose of a tourniquet cuff is to safely stop or restrict arterial blood flow into a portion of an extremity by applying a uniform circumferential pressure around the extremity at a desired location. Pneumatic tourniquet cuffs In general, a pneumatic tourniquet cuff is [...]

Tourniquet Cuff Selection

Are you selecting a tourniquet cuff that meets all FDA requirements as a Class I medical device? In the United States, pneumatic tourniquet cuffs are regulated as Class I medical device by the Food and Drug Administration (FDA). Risks of injuries to patients and legal liability for users arise from use of a pneumatic tourniquet [...]

Tourniquet Cuff Application

Proper Tourniquet Cuff Application: After the patient is brought into the OR, apply the tourniquet cuff at the desired location on the limb, pressurized within the appropriate pressure range for an appropriate period of time. The following sections provide a general sequence of events for preparation, cuff application and setting up the tourniquet instrument (Note: [...]

Safety Considerations During Use

The following should be considered during tourniquet use to reduce the risk of tourniquet-related complications: Intraoperative monitoring Tourniquet deflation Bilateral procedures Intravenous Regional Anesthesia procedures Documentation Troubleshooting Intraoperative monitoring Intraoperative monitoring of tourniquet safety parameters reduces the risk of complications. During the procedure, it is important to monitor the patient's blood pressure, tourniquet pressure, and [...]

Preoperative Patient Assessment

Patient Assessment The perioperative staff should assess the patient preoperatively for potential contraindications and risks [1]. The final decision on whether or not to use a tourniquet rests with the attending physician. Potential contraindications for tourniquet use Perioperative staff should screen the patient preoperatively for the following potential contraindications [1]: Venous thromboembolism, Impaired circulation or [...]

Personalized Scalp Tourniquets

Alopecia (hair loss) is a common consequence of cancer treatment known to have a profound impact on quality of life.  Tourniquet technologies have been investigated from the mid-1960s to early 1980s as a strategy for preventing chemotherapy-induced alopecia (CIA) but their ambiguous results precluded incorporation into any standard of treatment [1].  Fundamental advances inherent in [...]

Personalized Blood Flow Restriction (BFR) Rehabilitation

Why is it crucial to use personalized restriction pressures in blood flow restriction (BFR) rehabilitation? Problems in current BFR rehabilitation practice Blood Flow Restriction (BFR) applied to a limb during low intensity exercise has been shown to increase muscle size and strength across different age groups.  However, a review of BFR rehabilitation literature shows that inconsistencies [...]

Personalized BFR Rehabilitation for Patients with Possible Prior Nerve Injury

A question was raised recently as to whether it is safe and reasonable to conduct personalized BFR rehabilitation on a patient who may have a prior nerve injury.  After consideration of the evidence-based clinical literature, and in consultation with experts in neurology and orthopedic/arthroscopic surgery, the following information is provided in response: There is no [...]
