| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To compare the performance of 50 mg of Chloroprocaine 1% in intrathecal anaesthesia vs. a gold standard product 10 mg of Bupivacaine 0.5% isobar |
|
| E.2.2 | Secondary objectives of the trial |
| Comparison between test and reference in terms of the following parameters: Time to onset to motor block; the level of motor block is assessed by using the modified Bromages scale Maximum level of sensory block Resolution (Offset) of sensory block to S1 Resolution of motor block (Bromage score = 0) Time to unassisted ambulation Presence of urinary retention requiring catheterisation Time when patient asks the first time for analgesia Time to eligibility for home discharge (for day surgery only) |

| E.4 | Principal exclusion criteria |
| Clinically relevant abnormalities at ECG (12 leads); Clinically relevant abnormal physical findings and clinically relevant abnormal laboratory values indicative of physical illness/es that in the opinion of the Investigator might interfere with the aim of the study Ascertained or presumptive hypersensitivity to the active principle and/or formulations ingredients Ascertained or presumptive hypersensitivity to the amide type of anaesthetics ASA physical status III, IV or V; Patients requiring further anaesthesia (i.e. gas products); Lactating females; Positive pregnancy test at screening History of neuromuscular diseases to the lower extremities, Contraindication to spinal anaesthesia Participation in the evaluation of any drug within 3 months prior to screening; Blood donations during the 3 months prior to this study; History of drug, or alcohol abuse |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| To determine the non inferiority of 50 mg Chloroprocaine 1% versus the 10 mg bupivacaine 0.5% in terms of the onset of surgical anaesthesia, i.e. in terms of the time to achieve the sensory block at T10 (assessed by the loss of pin-prick sensation) |
