The Effect of Different Doses (Mass) of Local Anesthetic on Duration of Adductor Canal Block in Healthy Volunteers - Part 2
To investigate whether increased dose of local anesthetic (lidocaine) increases duration of peripheral nerve block (adductor canal block) and to develop a model for assessing duration of peripheral nerve blockades. The investigators hypothesize that increasing the dose of lidocaine (by increased concentration) will increase the duration of an adductor canal block.
The study is a follow up on an identical study (SM1-PJ-13, EudraCT number: 2013-001822-24 ) made earlier with different concentrations of lidocaine and a placebo group. For further information see trial registration at European Union Drug Regulatory Authorities Clinical Trial System.
