GENERAL INFORMATION
CAUTION: United States federal law restricts this device to sale by, or on the order of a physician.
NOTES: Use this tourniquet system according to the policies in your practice setting. The following information on
intended use, precautions, contraindications, and adverse effects are offered as a guide to assist in this process
INTENDED USE
The Delfi PTS ii Portable Tourniquet System is intended to be used by qualified medical professionals to exert enough
pressure on the arterial blood flow in a limb to produce a bloodless operating field. Tourniquets are generally used for
operations lasting less than 90 minutes. Tourniquets have been found useful in surgical procedures involving the
extremities, such as:
•Reduction of certain fractures
•Kirschner wire removal
•Tumor and cyst excisions
•Knee joint replacements
•Arthroscopy of certain joints
•Replacement of finger joints
•Bone grafts
•Amputations
•Subcutaneous fasciotomy
•Nerve injuries
•Tendon repair
•Total wrist joint replacement
CONTRAINDICATIONS
Refer to the medical literature for possible contra-indications to tourniquet use. A partial list is provided below;
however, in every case the final decision to use a tourniquet rests with the attending physician.
•Open fractures of the leg
•Post traumatic lengthy hand reconstruction
•Severe crushing injuries
•Elbow surgery (where there is concomitant excess swelling)
•Severe hypertension
•Skin grafts in which all bleeding points must be readily distinguished
•Compromised vascular circulation, e.g., peripheral artery disease
•Diabetes mellitus
•Secondary or delayed procedures after immobilization
The presence of sickle cell disease is a relative contraindication (see Precautions in Use under Section 1 General
Information).
WARNINGS
Do not use tourniquet cuffs to control the distal flow of CO2 or any other gases used as a distention media. Tourniquet
cuffs have not been evaluated for safety or effectiveness in controlling gas flow beyond the surgical site during
arthroscopic insufflation procedures. Possible effects of using a tourniquet cuff in this manner include serious
subcutaneous emphysema proximal to the cuff.
The tourniquet instrument should only be connected to a tourniquet cuff known to be in operable condition.

PRECAUTIONS IN USE
System Handling:
•The tourniquet system must be kept well calibrated and in operable condition. Accessories should be checked
regularly for leaks and other defects.
•The tourniquet cuff must never be punctured; therefore, towel clips used near the system must be handled with
special care.
•When cleaning, carefully follow the cleaning and assembly instructions for the tourniquet cuff and instrument,
refer to Section 3 Maintenance.
Patient Considerations:
•When using a tourniquet on patients with sickle-cell disease or trait, severe post-use pain may result in the applied
limb which may be caused by sickling of cells. Test for hemoglobin type and level before using a tourniquet on
patients with sickle cell anemia. When the tourniquet is used for these patients, the limb should be carefully
exsanguinated and the PO2 and pH should be closely monitored.
•Prolonged ischemia may lead to temporary or permanent damage to tissues, blood vessels, and nerves. Prolonged
tourniquet time can also produce changes in the coagulability of the blood with increased clotting time. In severe
cases, pooling of blood in the edemic limb may cause cardiac arrest and death. Rhabdomyolysis may develop in
patients following orthopedic cases where tourniquets have been inflated for extended periods of time (over 90
minutes). Always minimize tourniquet time.
•Tourniquet paralysis may result from excessive pressure. Insufficient pressure may result in passive congestion of
the limb with possible irreversible functional loss. Always use the minimum effective tourniquet pressure, as
described in the medical literature.
The following clinical conditions have been cited in published medical literature as factors that should be carefully
considered before use of a tourniquet during surgical procedures
•Severe atherosclerotic disease and presence of calcified vessels
•Severe brain injury
•Proven or suspected deep vein thrombosis
•Tumor on the surgical site
•Abscess or other limb infections
•Rheumatoid arthritis and other immune disease with vasculitis
•Poor cardiac reserve
•Fragile skin and soft tissue
•Compartment syndrome
•Hemoglobinopathy
•Previous revascularization of the extremity
•Extremities with dialysis access (e.g. arteriovenous grafts, fistulas)
•Acidosis
•Medications (e.g. antihypertensives) and supplements (e.g. creatine)
•History of pain or weakness in muscles or bones in extremities
•Increased intracranial pressure.
Delfi recommends that users regularly review published medical literature for other factors that warrant careful
consideration before use of a tourniquet during surgical procedures.

User Considerations:
•Careful and complete exsanguination reportedly prolongs pain-free tourniquet time and improves the quality of
Intravenous Regional Anesthesia (Bier Block anesthesia). However, partial exsanguination may be desirable in
certain cases where residual blood flow will aid in visualization and identification of vascular structures.
•In the presence of infection and painful fractures, after the patient has been in a cast, and in amputations due to
malignant tumors, exsanguination before tourniquet application may be done without the use of an elastic bandage
by elevating the limb for 3 to 5 minutes.
•Tourniquet users must be familiar with the inflation / deflation sequence when using two tourniquet cuffs and two
PTS ii units together for IVRA (Bier Block anesthesia), so that the wrong tourniquet will not be released accidentally,
which could cause severe injury to the patient or death.
•Whenever infiltration anesthesia is used, it has been suggested in the medical literature that the tourniquet remain
inflated for a minimum of 20 minutes from the time of the injection to ensure that most of the anesthetic agent has
been absorbed into the limb tissue. For a procedure requiring only a few minutes, too rapid a release of the
anesthetic agent can be prevented by quickly deflating and reinflating the tourniquet several times.
•Do not allow preoperative skin preparations to flow and collect under the cuff where they may cause chemical
burns.
•Inflation must be done as rapidly as possible to occlude arteries and veins simultaneously, and to avoid return of
blood into the limb. Quick deflation aids preventing engorgement.
•Heat generated by surgical lights or powered instruments is not dissipated in limbs under tourniquet control and
tissue may be subject to drying or trauma. Frequent irrigation, special draping and low power surgical lights are
recommended to reduce the risk of thermal damage.
Application and Use:
•Select the proper cuff size to allow for the overlap recommended by the manufacturer. Too much or too little
overlap may cause cuff rolling and telescoping, unexpected release of the cuff from the limb, inability to maintain a
bloodless field at normal pressures, and/or undesired pressure distribution on the limb.
•The skin under the tourniquet cuff must be protected from mechanical injury by smooth, wrinkle free application of
the cuff. If the tourniquet cuff is applied over any material that may shed loose fibers (such as Webril) the fibers may
become embedded in the contact closures and reduce their effectiveness. Follow the cuff manufacturer’s
recommendations for limb protection material under the cuff. In general, a limb protection sleeve designed
specifically for the cuff provides the best protection.
•The tourniquet cuff must be applied in the proper location on the limb. Tourniquet pressure and the time the
tourniquet is inflated on the limb should both be minimized. There is additional potential risk to superficial nerves
in unprotected areas; never apply a tourniquet over an area where major nerves may be directly compressed
against bone (e.g. peroneal nerve near the proximal head of the fibula). Never apply a tourniquet over the joints of
the limb. Do not readjust an already inflated cuff by rotating it because this produces shearing forces which may
damage the underlying tissue.
•Do not use an elastic bandage for exsanguination in cases where this will cause bacteria, exotoxins, or malignant
cells to spread to the general circulation, or where it could dislodge thromboemboli that may have formed in the
vessels.
•Observe the cuff during inflation and periodically while inflated to ensure the cuff is not migrating on the patient’s
limb.
•In case of incomplete or improper inflation, the tourniquet cuff must be fully deflated, and the limb exsanguinated
again before cuff reinflation. Reinflation over blood-filled vasculature may lead to intravascular thrombosis.
•If the tourniquet cuff migrates on the limb during surgery, apply a pressure dressing to the wound and exsanguinate
the limb by elevation. Deflate and reapply the cuff. Reinflate the cuff and observe for migration. If migration
persists, replace the cuff.
•Whenever the tourniquet cuff pressure is released, the wound should be protected from blood surging back by
applying pressure dressings and, if necessary, elevating the limb. Transient pain upon tourniquet pressure release
can be lessened by elevation of the limb. If full color does not return within 3 to 4 minutes after release, the limb

should be placed in a position slightly below body level.
•Completely remove the delated cuff, matching Limb Protection Sleeve or any underlying padding immediately
following final cuff deflation. Even the slightest impedance of venous return may lead to congestion and pooling of
blood in the operative field. After the cuff has been fully deflated and removed from the patient, the unit can be set
to STANDBY.
ADVERSE EFFECTS
A dull aching pain (tourniquet pain) may develop throughout the limb following use. Stiffness, weakness, reactive
hyperemia, & skin discolouration may also occur to some degree in all patients after tourniquet use.
Pathophysiologic changes due to pressure, hypoxia, hypercarbia, and acidosis of the tissues occur and become significant
after about 1 1/2 hours of tourniquet use.
Symptoms of tourniquet paralysis are motor paralysis and loss of sense of touch, pressure, and proprioceptive responses.
Intraoperative bleeding may be caused by:
•The slight impeding effect exerted by an unpressurized cuff (and its limb protection material or padding, if used),
which prevents venous return at the beginning of the operation,
•Blood remaining in the limb because of insufficient exsanguination,
•Inadequate tourniquet pressure (between systolic and diastolic blood pressure of the patient), or slow inflation and
deflation, all of which allow arterial blood to enter while preventing venous return,
•Blood entering through the nutrient vessels of the long bones, such as the femur or humerus.
Some other adverse effects of tourniquet use identified in the published medical literature include:
•Cardiovascular, respiratory, cerebral circulatory, and hematological effects related to the metabolic changes that
result from ischemia caused by the pneumatic tourniquet applied to the extremity during surgery.
•Temperature changes
•Prolonged postoperative swelling of the affected limb
•Arterial injury
•Skin injuries (e.g. blistering, bruising, necrosis)
•Compartment syndrome
•Deep Vein Thrombosis
•Rhabdomyolysis
•Skin chemical burns caused by solutions used for operative preparation passed underneath the tourniquet cuff and
remaining there during inflation
•Tissue or muscle injury may occur due to ischemia and local pressure
•Reperfusion injury may occur to the limb and produce systemic effects if the tourniquet inflation is prolonged
•Hematoma
Delfi recommends that users regularly review published medical literature for other adverse effects that warrant
careful consideration before use of a tourniquet during surgical procedures.
