Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Spinal Anesthesia

Intervention: spinal administration of articaine (Drug); spinal administration of bupivacaine (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Reinier de Graaf Groep

Official(s) and/or principal investigator(s):
Tessa Dijkstra, drs, Principal Investigator, Affiliation: Reinier de Graaf Groep

Summary

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.

Clinical Details

Official title: Spinal Anesthesia With 5% Articaine and 0.5% Bupivacaine for Outpatient Lower Limb Surgery. A Double-Blind Randomised Clinical Trial

Study design: Treatment, Randomized, Double-Blind, Active Control, Parallel Assignment, Safety/Efficacy Study

Primary outcome: recovery time from motor blockade

Secondary outcome:

onset of sensory and motor blockade

maximum spread of sensory blockade (30 min after spinal injection of anesthetic)

spread of sensory blockade after 1,5 hour

recovery time from sensory blockade

time to micturation

complications

Detailed description: 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.

Endpoints are:

- onset of sensory and motor block

- maximum spread of sensory level

- recovery from sensory and motor block

- time to micturition

- complications
