Femoral Artery Block for Reduction of Tourniquet Induced Hypertension

Femoral Artery Block for Reduction of Tourniquet Induced Hypertension: a Randomised Controlled Trial

A randomised controlled trial to assess the impact of femoral artery block on the incidence of tourniquet hypertension in patients receiving cruciate ligament surgery with > 30 minutes of tourniquet under combined anaesthesia (balanced general anaesthesia and femoral nerve blocks).

Inclusion Criteria:

• American Society of Anesthesiologists (ASA) physical status I to III
• Receiving cruciate ligament surgery with > 30 minutes of tourniquet
• Combined anesthesia (balanced general anesthesia and femoral nerve block)

Exclusion Criteria:

• Nerve block contraindications (block site infection, allergic to local anesthetic)
• Tourniquet contraindications (peripheral vascular disease or neuropathy, previous arterial bypass graft)
• Tourniquet inflation time < 30 min
• Patient refusal
• Pregnant patients
• Patients with a active psychiatric disease.
