Effect of Bilateral Rhomboid Intercostal Block on Postoperative Pain After Breast Implant Surgery

This prospective, randomized, single-center, study aims to evaluate the postoperative analgesic effectiveness of bilateral Rhomboid Intercostal Block (RIB) in patients undergoing elective bilateral breast prosthesis surgery. Effective postoperative pain management is essential to improve patient comfort and reduce opioid consumption. Eligible patients aged 18-65 years with ASA physical status I-II will be randomly assigned to either receive ultrasound-guided bilateral RIB block in addition to standard general anesthesia or undergo surgery without any regional block (control group). All patients will receive standardized general anesthesia and postoperative patient-controlled analgesia (PCA) with intravenous tramadol. The primary outcome of the study is total tramadol consumption within the first 24 postoperative hours. Secondary outcomes include postoperative pain scores at predefined time points, time to first analgesic requirement, need for rescue analgesia, incidence of nausea and vomiting, and block-related complications. The results of this study will help determine whether bilateral RIB block provides superior postoperative pain control compared to standard analgesic management alone in bilateral breast prosthesis surgery.

Post-market Prospective Clinical Study of Nagor Perle Mammary Implants

Patients can undergo breast implant surgery for multiple reasons; cosmetic and reconstructive being the primary indications. In order to confidently state safety and due to strict regulation on medical devices it is important to maintain a record of safety and performance with all medical implants. This study is designed to collect data on a new generation of smooth mammary implants to assess the long term performance and safety data on this type of gel-filled mammary breast implant. The two main complications of breast implants are capsular contracture and rupture; these complications can take years to develop. The study is designed to evaluate the occurrence of these two primary complication as well as other secondary complications over a period of 10 years. Patient follow up will be carried out pre-operatively and post operatively at 12 months and then 3, 5, 8 and 10 years thereafter. The study will be carried out over 10 years to adequately assess complications which may only occur over the lifetime of the device such as systemic complications

Safety and Performance of Motiva® Sizers

The Motiva® Sizer clinical study is a four-year, multicenter, post-marketing, and cohort study, designed to confirm the safety and performance of Motiva® Sizer in breast augmentation or reconstruction procedures. The research will include 330 women, divided into two groups of 165 participants each (150 breast augmentation participants and 15 reconstruction participants). The Motiva® Sizer exposed group will consist of women who will undergo breast augmentation or reconstruction surgery with the use of Motiva® Sizer during the procedure, and a non-exposed group will consist of women who will undergo breast augmentation or reconstruction surgery without the use of Motiva® Sizer. This study will be conducted in Costa Rica. The main goal is to evaluate the safety and the performance of the Motiva® Sizer. To this end, the results of both groups will be compared in terms of surgical complications, surgeon's, and participant's satisfaction level as well as reoperation rates. After the augmentation or reconstruction surgery, participants will be scheduled for the following follow-up visits, (1) between 3 and 7 postoperative days, (2) between 3 and 6 postoperative weeks, (3) at 3 and (4) 6 postoperative months, and (5, 6 and 7) annually thereafter for a period of three consecutive years. In case any participant has an adverse event due to the procedure, and if required by the physician, an additional visit will be made to assess her, and this information as well as that of the scheduled visits should be recorded in the electronic data collection notebook.
