Spinal Anesthesia With Articaine and Bupivacaine for Outpatient Lower Limb Surgery
The purpose of the trial is to compare two local anesthetics, articaine and bupivacaine for outpatient lower limb surgery. Onset and recovery times of sensory and motor blockade will be compared.

The purpose of the trial is to compare two local anesthetics, articaine and bupivacaine for outpatient lower limb surgery.
Faster onset and shorter elimination time favours a short-acting local anaesthetic for spinal anesthesia for out-patient lower limb surgery, e.g. knee arthroscopy, foot and varices surgery. Patients will recover faster and less complications will be expected.
Articaine is said to act faster and shorter than a low dose of bupivacaine. There are not enough data available to establish that articaine is as safe as and more effective by outpatient lower limb surgery than bupivacaine.
Spinal anesthesia with articaine will be compared to spinal anesthesia with bupivacaine in a randomized double blind clinical trial.
- onset of sensory and motor block
- maximum spread of sensory level
- recovery from sensory and motor block
- time to micturition
