SECONDARY outcome

Timeframe: During the first 24 hours after surgery and at the entry and exit of the resuscitation unit

To assess whether the administration of morphine chloride in addition to a low dose solution of local intradural anaesthetic (bupivacaine) improves the mobilization of the patients after surgery more than the single intradural administration of bupivacaine. Total Score in the Bromage Scale goes from 1 to 5, where: 1: complete motor blocking - 2: capable to move the feet - 3: moves the feet and bends the knee - 4: raise the leg straight more or less than 30 degrees but no against resistance - 5: raise the leg straight more than 30 degrees against resistance (no motor blocking)
