Prolongation of Pain Free Time by the Use of Dexamethasone in Peripheral Nerve Blockade

Landesklinikum Sankt Polten109 enrolled

Overview

The main aim of the study is to investigate the proven effect of dexamethsone on the duration of the interscalene block. The investigators try to define optimal dose and volume for ropivacaine, when used together with dexamethsone. The current literature uses often very high volumes of ropivacain when used together with dexamethasone. The investigators try to research the effect of using dexamethsone together with low volume, high concentration ropivacaine for interscalene blockade. The investigators' hypothesis is that dexamethasone has an positive effect on the pain free after used together with ropivacaine at the scalene block.

Outcomes

Primary Outcomes

Pain free time measured by the duration between block and the point at which the patient is asking for painkillers

Time frame: Patients will be followed during their stay at the hospital, which will be normally around 24 to 48 hours.

Secondary Outcomes

Visual Rating Scale for Pain at Movement and Rest

Time frame: Measured 10 hours after the intervention
