Erector Spinae Versus Paravertebral Nerve Blocks for Breast Surgery

Start date: July 12, 2018
Phase: Phase 4
Study type: Interventional

Following painful surgical procedures of the breast, postoperative analgesia is often provided with a paravertebral nerve block (PVB). For intense, but shorter-duration acute pain, a single-injection of local anesthetic is used with a duration of approximately 12 hours. The PVB has several limitations: it can decrease blood pressure, and very rare—but serious—complications have occurred, including neuraxial injection, neuraxial hematoma, and pleural puncture. An alternative block has been described: the erector spinae plane block. The theoretical benefits include ease of administration since it is a plane superficial to the PVB and therefore easier to identify and target with ultrasound (therefore increasing success rate); and an increased safety margin: there are few anatomic structures in the immediate area which could be injured with the needle; and, the target plane is much further from the intrathecal/epidural space relative to the PVB. Lastly, the plane may be easier to catheterize for continuous peripheral nerve blocks relative to the relatively-small volume PVB. There are therefore multiple theoretical reasons to prefer the erector spinae plane block. Unfortunately, it remains unknown if the analgesia provided by this new technique is comparable to that provided with the PVB. The investigators therefore propose to compare these two techniques with a randomized, subject-masked, active-controlled, parallel-arm, human subjects clinical trial.

NCT ID: NCT03344679 Completed - Breast Surgery Clinical Trials

Adenosine and Magnesium Sulphate as Adjuvants for PECS Block.

Start date: February 1, 2015
Phase: N/A
Study type: Interventional

Pectoral nerve block (PECS) has been used for post-operative pain relief in patients undergoing breast surgery. It has been shown that adenosine has an effect on pain modulation. Magnesium sulphate has been used as an adjuvant to local anaesthetics in many nerve block techniques. We hypothesised that adenosine may affect the PECS block quality. We aimed to compare the effect of adding adenosine to the local anaesthetic and compare its effect to magnesium sulphate when used for PECS block.

NCT ID: NCT02250898 Completed - Pain Clinical Trials

Massage for Post Breast Surgery

Start date: September 2014
Phase: N/A
Study type: Interventional

The aims of this study are to determine the effectiveness of myofascial massage specific to the breast/chest/shoulder area in reducing self-reported pain and increasing mobility among patients who have undergone a mastectomy or other breast surgery compared to a control group receiving global relaxation massages.

NCT ID: NCT02222675 Completed - Breast Surgery Clinical Trials

Conserving Breast Surgery - Comparison of Conventional With Sonography

MAC-001
Start date: April 2009
Phase: N/A
Study type: Interventional

Aim of the study is to test whether surgical removal of a tumor under sonographic control as compared to conventional method reduces the rate of resections and local relapse

NCT ID: NCT01993771 Completed - Breast Surgery Clinical Trials

Monitoring of Anaesthesic Depth in the Cerebral Cortex Using Bispectral Bilateral System.

Start date: September 2013
Phase: N/A
Study type: Observational

This is a prospective, observational study, aimed to establish changes of bispectral bilateral system in both cerebral hemispheres during a total intravenous anaesthesia during breast surgery in the woman. By placing two Bispectral bilateral sensors (BIS), one on both frontal lobes, and another on both parietal lobes, we wanted to evaluate differences between frontal and parietal areas, when the patient is awake and during the anaesthetic procedure.

NCT ID: NCT00605670 Completed - Breast Cancer Clinical Trials

Measuring Patient Satisfaction and Quality of Life Following Body Image Altering Surgery

Start date: June 2005
Phase: N/A
Study type: Observational

The goal of this study is to develop a questionnaire to measure patient satisfaction with their breast surgery. This questionnaire will help surgeons better understand how patients feel about their surgical results. We hope that such a questionnaire will improve the understanding of breast surgery results and patient care.
