Erector Spinae Plane Block
All volunteers will be given the choice of procedural pain relief in the form of rapifen 0,5-1 mg. All volunteers included will receive an unilateral ESPB at the T7 level with 30 ml of 2,5 mg/ml ropivacaine and a total of 0,3 mmol gadolinium. The intervention will be performed by the PhD candidate connected to the study. The ESPB will be performed under ultrasound guidance, where the needle target is the transverse process of the Th7 vertebra, under the musculus (m.) erector spinae. All volunteers will be tested for cold and pinprick sensation 30 minutes after block completion, and the results plotted on a dermatome map before they undergo an MRI.
