Randomized Controlled Trial Comparative StudyLignocaine is a better analgesic than either ethyl chloride or nitrous oxide for peripheral intravenous cannulation.
Peripheral intravenous (i.v.) cannulation is a painful, frequently performed ED procedure. It is common practice in other medical settings to offer analgesia prior to cannulation. ⋯ The present trial confirms the findings of Harris and colleagues that lignocaine reduces the pain of cannulation in the ED. Lignocaine reduced the pain of i.v. cannulation more effectively than entonox or ethyl chloride.
