The purpose of this study is to assess Ketamine as an adjuvant to Branchial Plexus Blockade.
After being informed about the study, patients giving written informed consent will undergo anaesthesia using the Ultrasound Guided Axillary Approach to Brachial Plexus Blockade, in order to undergo forearm surgery. The purpose of this study is to assess whether Ketamine as an adjuvant lengthens sensory and motor blockade and whether it has an effect on "rebound pain" when the anaesthetic effect fades. Therefore the study will compare intravenous, regional and no administration of Ketamine as an adjuvant to Branchial Plexus Blockade. Patients will be asked to fill in a Pain VAS (Visual Analog Scale) for 24 hours following the intervention, in order to assess effectiveness of each anaesthetic method. Side effects, onset time, motor blockade score and rescue dose are also recorded.

Side Effects
Dizziness, nausea, vomiting, paraesthesia
Time frame: 24 hours
Motor Blockade Score
0=complete paralysis, 1=partial paralysis, 2=no paralysis
Time frame: 24 hours
Anesthesia Onset time
Time from removal of needle to final motor and sensory blockade result
Time frame: 24 hours
Rescue Dose
Tramadol 100mg intravenously administered only to patients who claim to be in strong pain within the 24 hours after intervention.
Time frame: 24 hours
