These complications were due to incorrect use of hypertonic saline in flushing the IV catheter, incorrectly prepared solutions, excessively long periods of tourniquet inflation, and Analgesic effect typically remains for up to two hours depending on the dosage and type of anesthetic agent being used. 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.
