Scientific titleComparison of 0.5ml vs. 1.0ml vs. 1.5ml hyperbaric prilocaine 2% for spinal saddle block in patients undergoing perianal surgery in an ambulatory setting
Study objectivesIn 2010 hyperbaric prilocaine 2% was introduced on the German market. There is no evidence based data about dosing of hyperbaric prilocaine 2% for perianal surgery. In this trial we compare the expansion of the saddle block according to three dosages of hyperbaric prilocaine 2%.
Ethics approval(s)Medical Ethics Committee II, Faculty of Medicine, Ruprecht Karl University of Heidelberg (Medizinische Ethikkommission II: MEdizinische Fakultät Mannheim der Ruprecht-Karls-Universität Heidelberg), approved on 21st September 2010 (ref: AZ.: 2010-303N-MA)
Health condition(s) or problem(s) studiedColorectal diseases
InterventionParticipants are randomised (1:1:1) to a dose of either 0.5ml or 1.0ml or 1.5ml of hyperbaric prilocaine 2%. The expansion of anaesthesia is tested with a toothpick and an ice-filled plastic tube.
Intervention typeDrug
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Prilocaine 2%
Primary outcome measure(s)

Expansion of anaesthesia tested with a toothpick and an ice-filled plastic tube. The expansion of anaesthesia is tested at two points of time:
1. After positioning of the patient for operation
2. Directly after the procedure has ended

Key secondary outcome measure(s)

1. Practicability
2. Postoperative analgetic consumption
3. Duration of stay in hospital
