Brief summary

The goal of this clinical trial is to evaluate if CO2 Lift reduces bruising and pain after Liposuction. The study also aims to explore changes in patient satisfaction. The main questions this study seeks to answer are: * Does CO2 lift reduce the extent of bruising at 7 days post-surgery? * How does CO2 lift impact patient-reported pain and satisfaction? In this study, researchers will compare CO2 lift to a placebo (Vaseline) to see if the intervention has a positive effect. The study procedures include: * Baseline data collection of sociodemographic variables. Data collection of surgical variables, adverse events, pain scores, and satisfaction scores. * During the liposuction procedure the patient will receive CO2 Lift application to one arm, and/or one glute, and/or one half of the lower abdomen, and placebo (Vaseline) to the contralateral part. * Apply CO2 lift and Vaseline immediately after surgery, 12 hours later, and then once a day for 3 to 5 days depending of the risk of the flap/skin. * Postoperative follow-up with photos of treated areas at 24 hours, 3 days, and 7 days, with bruising quantified using Image J software.

Detailed description

Study Design: Randomized, controlled, single-blind trial * Allocation: Randomized (one area with CO2 lift treatment, one area with Vaseline control) * Intervention Model: Comparative contralateral randomized clinical trial (each participant serves as their own control, with CO2 lift applied to one area and Vaseline to the contralateral area). * Masking: Single-blind (Participants are blinded to the treatment allocation). Study Locations: * Dhara Clinic, Bogota, Colombia * Private Practice, Sao Paulo, Brazil * Private Practice, Mexico City, Mexico Data Collection: * Photographic analysis with ImageJ, from photo records from days 1, 3, 7 post procedure, to calculate the percentage of the area with ecchymosis. * Pain Assessment: Visual Analogue Scale (VAS) scores recorded at the same time points. * Satisfaction Scores: Global Aesthetic Improvement Scale (GAIS) evaluated at least 3 months postoperatively. Ethical Considerations: * Informed Consent: Participants will be provided comprehensive information about study procedures, risks, and benefits, and written consent will be obtained. * IRB Approval: The study will adhere to the Declaration of Helsinki principles and will be approved by an Institutional Review Board (IRB). * Data Confidentiality: All participant data will be anonymized and securely stored.

Design outcomes

Primary

MeasureTime frameDescription
Ecchymosis of the area - 7 days post procedure7 daysReduction of ecchymosis in each area, measured using Photomicrographic analysis with ImageJ Software. The unit of measurement will me in cm\^2 of the affected area (bruised) normalized to the total area of the area (in cm\^2).

Secondary

MeasureTime frameDescription
Ecchymosis of the area - 24 hours post procedure24 hoursReduction of ecchymosis in each area, measured using Photomicrographic analysis with ImageJ Software. The unit of measurement will me in cm\^2 of the affected area (bruised) normalized to the total area of the area (in cm\^2).
Ecchymosis of the area - 3 days post procedure3 daysReduction of ecchymosis in each area, measured using Photomicrographic analysis with ImageJ Software. The unit of measurement will me in cm\^2 of the affected area (bruised) normalized to the total area of the area (in cm\^2).
Pain Score7 daysPatient-reported pain measured using Pain Visual Analogue Scale (VAS), measured at 24 hours, 3 days, and 7 days post-procedure. In the VAS pain scores, 0 represents no pain, while 10 represents the worst possible pain experienced.
Patient Satisfaction Scores6 monthsPatient reported satisfaction scores measured using Global Aesthetic Improvement Scale (GAIS). The GAIS is a standardized scale used primarily in cosmetic and dermatological treatments to assess the overall aesthetic improvement of a patient after a procedure. It consist of three questions: \* how do you feel about your appearance after surgery? Possible answers: Very much improved, much improved, slightly improved, no change. \* Are you satisfied with the surgery? Very satisfied, satisfied, not satisfied. \* Would you recommend the surgical procedure? Possible answers: Yes, perhaps, no.
