Active Comparator
Deep serratus anterior plane block
Surgically-placed paravertebral block
Ultrasound-guided deposition of 40mls of 2mg/ kg levobupivacaine into the deep serratus anterior plane space, in the mid axillary line, at the level of the 4th/5th rib. Insertion of a continuous local anaesthetic infusion catheter(Portex™) and continuation of an infusion of 0.125% levobupivacaine at a rate of 8-12mls/ hour for 48 hours.
Surgical placement of paravertebral local anaesthetic infusion catheters (Portex™) prior to closure. Bolus of levobupivacaine as per protocol. Continuation of an infusion of 0.125% levobupivacaine at a rate of 8-12mls/ hour for 48 hours.
