An interventional study of Ultrasound guided paravertebral block in Regional Anaesthesia, Mastectomy and Breast-Conserving Surgery, sponsored by University College Hospital Galway. Status unknown at 1 site in Ireland. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2015-12-07.
Sponsored by University College Hospital Galway · Not applicable, Interventional, and Supportive care
The aim of this study is to compare conventional and ultrasound guided paravertebral blocks to with respect to efficacy, patient satisfaction and complication rates.
Adequate pain control is important in breast cancer surgery. In addition to benefits to patients, effective pain management strategies also facilitate day case surgery. Regional anaesthetic techniques, and paravertebral blocks in particular, are valuable in this sphere. The conventional method of administering this block is blind and depends on anatomical landmarks for placement. Performing the block under US guidance provides real time imaging while advancing the needle. This might allow for a more accurate placement and hence a more effective block which would enhance pain relief and minimise complications.

Exclusion Criteria:
Patients receiving a conventional paravertebral block of dilute local anaesthetic (eg. 5ml of 0.5% bupivacaine or similar) administered using anatomical landmarks
Procedure: Ultrasound guided paravertebral block
Patients receiving paravertebral block of dilute local anaesthetic (eg. 5ml of 0.5% bupivacaine or similar) administered under ultrasound guidance
Procedure: Ultrasound guided paravertebral block
Paravertebral blocks is a regional anaesthetic technique in which thoracic spinal nerves are inhibited for post operative analgesia in patients undergoing breast surgery. The site of injection can be determined using anatomical landmarks (standard) or using ultrasound guidance.
