Summary

The investigators aim to compare the quality of pain relief provided by local infiltration analgesia delivered by surgeon and Pecs block delivered by anaesthetist under ultrasound guidance for patients undergoing mastectomy with axillary dissection.

Detailed description

Total breast removal with armpit dissection may be a painful surgery. Pectoral nerve block (Pecs block) is common pain relief method used to reduce pain after breast surgery. The Pecs block is a pain relief method technique at targeted body part. The Pecs block numbs nerves which supply sensation to the upper chest wall, armpit and upper arm. This procedure is only possible under ultrasound guidance and is carried out by the anaesthetist (medical specialist who administers anaesthetics) after patients are put under general anaesthesia. Despite the advantages of Pecs block in pain management, this method is not always available to all patients due to various reasons. These reasons include the availability of ultrasound machine to facilitate the method, presence of anaesthetist to carry out the procedure and additional time required to perform this method in the operating theatre. Another method has been modified by our surgeons (medical specialist who performs surgery, a different specialty from anaesthetist) to achieve pain relief among patients undergoing breast removal surgery. This method is called local infiltration analgesia (LIA). The pain control is achieved by having the surgeons to deliver a pain control drug surgically during the breast removal operation. LIA could be a good pain control alternative when a Pecs block could not be performed. The investigators hope to compare the quality of pain relief provided by local infiltration analgesia delivered by surgeon and Pecs block delivered by anaesthetist under ultrasound guidance. The investigators hope to show that LIA delivered by surgeon is as effective as Pecs block in patients undergoing mastectomy with axillary dissection.

Interventions

Type	Name	Description
PROCEDURE	PECs Block	Regional Anaesthesia Technique ie Pectoralis Nerve Block under ultrasound guidance
PROCEDURE	Local infiltration	LIA will be performed by surgeon during the operation. The upper skin flap will be raised in the standard manner for mastectomy. The lateral border of the major pectoralis muscle will then be visualised. A volume of 10 ml ropivacaine 0.5% will be delivered between the inter-fascial planes of the pectoral muscles. The lower skin flap will then be raised in the standard manner for mastectomy and the breast is raised off the pectoralis muscle exposing the serratus anterior muscle. A volume of 20 ml ropivacaine 0.5% will be delivered between the muscle planes of the serratus anterior and pectoralis minor muscles.
