This is a double-blinded placebo-controlled interventional study that will performed in emergency department of a teaching hospital. All patients with traumatic hand fingers injuries who needed digital nerve block and older than 15 years will enter the study. Exclusion criteria are pregnancy, allergy to Ketamine or Lidocaine, communication problem and serious cardiovascular problems. Initial pain will be evaluated by Visual Analogue Scale. Patients will be randomly divided to two groups; Intervention group that receives 1cc of Ketamine and control group that receives 1cc of distilled water. The fluid will drop on one of nostrils of patients. 5 minutes later pain will be evaluated again and digital nerve block will be done as an standard and routine manner. The procedure will be performed after 5 minutes. Pain of block and procedure will be evaluated by VAS. Blood pressure and pulse rate will be measured before and right after 30 min after the procedure. Patients will be observed for half an hour for complications of Ketamine such as hallucination, nausea, vomiting, cough and other complications.
