Summary
Tourniquets are safe for limb surgeries, but can alter physiology. Patients with poor cardiac function may experience adverse effects from these physiological changes.
Area of Science:
- Orthopedic Surgery
- Anesthesiology
- Physiology
Background:
- Tourniquets are commonly used in limb surgeries worldwide.
- Tourniquet application induces physiological changes.
- These changes are generally well-tolerated by healthy individuals.
Approach:
- Systematic literature search of PubMed, MEDLINE, ScienceDirect, and Google Scholar.
- Included randomized controlled trials and systematic reviews.
- Summarized findings on tourniquet use, physiological effects, and safe practices.
Key Points:
- Tourniquet use alters normal physiology.
- Patients with compromised cardiac function may not tolerate these changes well.
- Review provides updates on safe tourniquet practices.
Conclusions:
- Tourniquet use requires careful consideration in patients with poor cardiac function.
- Understanding physiological alterations is crucial for safe application.
- Evidence-based review guides current tourniquet practices.

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.7K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
