Currently, paracetamol, ibuprofen and nonsteroidal antiinflammatory drugs are widely used by emergency physicians in Turkey for the treatment of fever . The objective of the study is compare the efficacy of intravenous ibuprofen and paracetamol in the treatment of patients with upper respiratory tract infections presenting with fever in the emergency department

This is the randomized double blinded clinical trial to compare the efficacy of these two drugs in this clinical setting. A randomized clinical trial was conducted in the Emergency Department (ED) of Pamukkale University Medical Faculty Hospital Study personnel (emergency physicians and emergency service nurses) were trained before the study. When intravenous drugs (Paracetamol and İbuprofen) was being recommended, an eligibility checklist was completed by the attending physician. patients who presented to the emergency department with upper respiratory tract infection and had a temperature above 38.0 ° C were measured by a fever gauge included into the study First Group: 1000 mg of paracetamol ( parol 10mg/ml solution Mefar, Turkey) intravenous (IV) was given 100 patients

Second Group:

Ibuprofen 400 mg ( intrafen 400mg/4ml solution -Gen ilaç san., Turkey) intravenous (IV) was given 100 patients which determined to be applied as a group. Drug packs prepared in 150 ml serum physiology were numbered by an independent nurse, who not involved in the study Randomization was achieved by using computer software to generate random numbers. During the intervention, participants were monitored by an oxygen saturation (SpO2) monitor, an automatic sphygmomanometer (blood pressure), and a rhythm monitor (heart rate and rhythms). Patients in both groups received two types of medication in a similarmanner, thus ensuring double blind.
