Clinical Trial Summary

In ambulatory surgery, the choice of the local anesthetic used is essential. The ideal local anesthetic must allow a quick installation of the spinal block, a duration of the sensory block adapted to the surgery with a minimum of side effects. These side effects include bradycardia, hypotension and block failure during the intraoperative period; bladder retention, transient neurological disorders during the post-operative period. The achievement of kinetic objectives associated with a reduction in side effects is related to the choice of local anesthetic and the dose administered. However, there are interindividual pharmacokinetic variations that make it difficult to predict the effective dose and the unfortunate occurrence of side effects.

In this context, the height of the patient is a criterion involved in the level, the duration of the sensitive motor block and therefore the side effects

The local anesthetic of the amino ester family, isobaric 2-chloroprocaine (2-CP) has been successfully used for spinal anesthesia since several decades. With a short duration of action, it is preferred to other anesthetics for the short-term outpatient surgeries. However, the effective dose 95 (ED95) of intrathecal isobaric 2-CP is currently unknown.

The purpose of this prospective study is to determine the ED95 of the spinal 2-CP using the continuous re-evaluation method (Continual Reassessment Method) (CRM) based on patient's height
