GALINDO GUALDRON, Luz Adriana. Test dose in regional anesthesia. Rev. colomb. anestesiol. [online]. 2014, vol.42, n.1, pp.47-52. ISSN 0120-3347.  https://doi.org/10.1016/j.rca.2013.10.003.

Introduction: The use of the test dose in regional anesthesia is not standardized, and there is no consensus regarding what dose it should be or about the anesthetic or type of drug to be used. Moreover, many anesthesiologists do not use it routinely in their practice. Objective: To review the test dose for regional anesthesia, its indications and utility, the drugs used, and positive signs. Methods: A non-systematic search was conducted in medical database publications inclu-ding MedLine, SciELO and Embase. Results:The applicationofthe test dose beforegiving the fullinjectionofthe local anesthetic helps in detecting the inadvertent placement of the needle or catheter in the intravascular or the subarachnoid spaces. Conclusions: The test dose must be used every time critical doses of a local anesthetic are utilized or when normal doses are given to patients with risk factors. The test dose is not necessary in labor analgesia.
