Locoregional Analgesia in Breast Surgery Clinical Trial
Official title:
A Randomised, Double-blind, Placebo-controlled Study to Assess the effectIveness of Pectoral Nerves Block (PECS) After Breast Surgery on Piritramide Consumption
The aims of this study is to compare the effectiveness of pecs block associated to a general anesthesia in terms of Piritramide consumption compared with a general anaesthesia alone and the chronic pain incidence in patients that undergoing either a lumpectomy or a mastectomy associated with axillary dissection This is a double-blind, placebo controlled study that will randomise breast cancer subjects in 1:1 ratio to receive a "pecs block" of Ropivacaine 3.5 mg/ml and Clonidine 5 µg/ml (arm A) versus placebo (arm B).
This is a double-blind study that will randomise breast cancer subjects in 1:1 ratio to receive a "pecs block" of 10 ml of Ropivacaine 3.5 mg/ml and Clonidine 5 µg/ml injected between pectoral muscles and 20 ml between the muscles pectoralis minor and serratus anterior (arm A) versus 10 ml of placebo (NaCl 0.9%) injected between pectoral muscles and 20 ml between the muscles pectoralis minor and serratus anterior (arm B). The pecs block will inject just before the surgery. Subjects will receive a nausea and vomiting prophylaxy depending on Apfel score After surgery, the two intervention groups will receive before waking a dose of Paracetamol (1 g) and Diclofenac (75 mg), if they present no contraindications and a dose of 0.05 mg/kg Piritramide . In the recovery room the two groups will benefit from a Patient Controlled Intravenous Analgesia (PCIA) pump - Piritramide allowing them to control their analgesia, which will be stopped at 24 hours postoperatively. ;
