This lower dose may decrease the incidence of central nervous system side effects and is more desirable in the ED setting. Bier block is a valuable technique for short procedures, but as the local anesthetic is being injected intravenously, it is important to make sure that the tourniquet is not released for at least forty five minutes which will give local anesthetics enough time to be absorbed slowly and to prevent any systemic toxicity. Plexus blocks - eg, brachial plexus. Nerve blocks - eg, femoral. Intravenous blocks whilst preventing venous flow out of the region - eg, Bier's block.
The wait time and isolation of blood flow from the region is important for avoiding an overdose of the anesthetic agent in the blood which can lead to hypotension, convulsions, arrhythmia and death. Adverse events associated with intravenous regional anesthesia (Bier block): a systematic review of complications Author links open overlay panel Joanne Guay MD, FRCPC ( Clinical Associate Professor )
There were no deaths or major complications identified in our study. Conclusion: Bier's block is a safe technique for reduction of fractures when used in the appropriate population and fracture types, with a low failure rate and no major complications including death. Compared to the ketamine group, it has a shorter length of stay in the emergency department. Bier block is a valuable technique for short procedures, but as the local anesthetic is being injected intravenously, it is important to make sure that the tourniquet is not released for at least forty five minutes which will give local anesthetics enough time to be absorbed slowly and to prevent any systemic toxicity. There were no intraoperative and no postoperative complications.

Severe toxicity may cause seizures, methaemoglobinaemia, cardiovascular and respiratory compromise. Local complications associated with tourniquet use include: Postoperative swelling and stiffness Delay in recovery of muscle power Compression neurapraxia Wound hematoma Wound infection Direct vascular injury Skin abrasions Bone and soft-tissue necrosis Deep vein thrombosis Compartment syndrome For another, significant hematoma formation at the site of the bone fracture was found at the fasciotomy. Because compartment syndrome is a known complication of Colles' fractures, the exact contribution of the Bier block in this specific case is difficult to determine .
