Conditions

Scorpion Stings

Brief summary

In scorpion stings, patients mostly apply with the complaint of pain. Emergency physicians need to relieve this pain quickly.

Detailed description

Aim: In this study, the analgesic efficacy of intravenous (IV) paracetamol, IV dexketoprofen trometamol and topical lidocaine will be compared in patients presenting with pain after scorpion sting. Methods: This study is a double-blind, randomized, placebo-controlled study conducted in a tertiary emergency department. Adult patients who applied to the study with no systemic findings after scorpion sting and especially with pain will be randomly assigned to one of 4 groups: IV paracetamol, IV dexketoprofen trometamol, topical lidocaine or placebo. In order to determine the intensity of pain, Visual Analog Pain Score (VAS) will be measured at the time of admission to the emergency department, at the 30th minute and at the 60th minute. Afterwards, the VAS score changes between the groups will be compared.
