Filter by:The purpose of the study is to evaluate the effect of continuous pectoral nerve block on postoperative analgesia consumption in breast cancer surgery.
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. Recently an alternative block has been reported: the serratus plane block.2 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 as there are fewer 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, therefore leakage of cerebrospinal fluid or injury to the spinal cord are less likely with the serratus compared to the PVB.3 There are, therefore, multiple theoretical reasons to prefer the serratus over the PVB. Unfortunately, it remains unknown if the analgesia provided by this new technique is comparable to that provided with the PVB.4 The investigators therefore propose to compare these two techniques with a randomized, subject-masked, active-controlled, parallel-arm clinical trial.
The purpose of the study is to evaluate the efficacy of PECS block applied to patients undergoing bilateral breast reduction surgery on postoperative analgesia compared to local infiltration anesthesia.
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.
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.
This study compare the "Serratus block plane" (SPB) and the local infiltration of the tissue in the prevention of acute and chronic pain after breast cancer surgery.
The aim of the study is to determine the effectiveness of serratus place block in the control of post-operative pain following mastectomy. The investigators will compare one group of patients receiving serratus plane block and wound infiltration to a control group receiving a saline injection into serratus anterior and wound infiltration with local anaesthetic only. The investigators will compare our results to the National Mastectomy and Breast Reconstruction Audit's reported rate of 6.2% of patients reporting severe pain following mastectomy to see if there is an improvement of the national standard. In the serratus block group, the investigators expect a 50% decrease in the number of patients who report severe pain day one post operatively.
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.
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
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.
