Spinal Anaesthesia—The Current Trend towards Narrow Gauge Atraumatic (Pencil Point) Needles. Case Reports and Review

Their use in all circumstances however, may not be appropriate in light of the problems which may be associated. These problems are illustrated here by four case reports and a review of the literature.
