About this study

Official title: Cold Versus Warm Tumescent Solution in Arm Liposculpture: A Double-blind Clinical Study.

The goal of this clinical trial is to evaluate whether the temperature of tumescent solution (cold vs. warm) affects postoperative outcomes in adults undergoing arm liposculpture. The study includes men and women aged 18-60 years with certain body complexity, however no obese patients are allowed to enter the study. All patients are undergoing bilateral arm liposculpture as part of body contouring procedures.

The main questions it aims to answer are:

Read more
  • Does using a cold tumescent solution reduce postoperative bruising compared to a warm solution?
  • Does a cold tumescent solution reduce postoperative inflammation compared to a warm solution?
  • How does solution temperature affect the quality of fat samples collected during liposuction?

Researchers will compare the cold tumescent solution group to the warm tumescent solution group to determine whether a lower temperature provides benefits in terms of reduced bruising, inflammation, and improved fat quality.

Participants will:

  • Receive either a cold (4°C) or warm (room temperature) tumescent solution in each arm before liposuction.
  • Undergo fat emulsification with VASER technology.
  • Have one arm treated with Power-Assisted Liposuction (PAL) and the other with Conventional Suction-Assisted Liposuction (SAL).
  • Have liposuction fat samples collected for analysis of fat content, blood content, and overall fat quality.
  • Be monitored for bruising and inflammation on Days 1, 3, and 7 using an image analyzing software and arm circumference measurements.
  • Complete a satisfaction survey 30 days after surgery.

Safety considerations include monitoring core temperature and using external warming devices if needed to prevent hypothermia.

Study Objective:

To compare the effects of cold (4°C) and warm tumescent solutions in arm liposculpture on postoperative outcomes, specifically in terms of inflammation, bruising, and fat emulsification using different liposuction techniques.

Study Design

  • Type: Interventional (Clinical Trial)
  • Allocation: Randomized
  • Intervention Model: Parallel Assignment
  • Masking: Double-blind (Participants and Surgeon)
  • Primary Purpose: Prevention of complications

Population: Adults aged 18-60 years scheduled for bilateral arm liposculpture together with other body contouring procedures.

Interventions

  1. Cold Tumescent Solution Group (Intervention arm)
  • Infiltration of tumescent solution at 4°C.
  1. Warm Tumescent Solution Group (Control arm) o Infiltration of standard tumescent solution (room temperature).

Tumescent Solution Composition (for both groups):

  • 7 cc of 2% Lidocaine without Epinephrine.
  • 1 mg of Epinephrine.
  • 250 mg of Tranexamic Acid.

Procedure Outline

  1. Infiltration Phase: Each arm is infiltrated with its respective tumescent solution (cold or warm). Allow a 15-minute diffusion period for the tumescent solution to take effect.
  2. VASER Emulsification: Apply VASER technology to both arms at 50% power for fat emulsification.
  3. Liposuction Techniques: Arm A: Liposculpture performed using Power-Assisted Liposuction (PAL). Arm B: Liposculpture performed using Conventional Suction-Assisted Liposuction (SAL).
  4. Fat is collected separately for each arm and stored in individual containers.
  5. Sample Collection for Analysis:
  • Collect a lipocrit sample in a 10 ml syringe from each arm.
  • Send the samples to pathology for analysis of fat content, blood content, and overall quality of the liposuction sample.

Primary Outcome Measures

  1. Postoperative Bruising: Assessed using ImageJ software to quantify areas of bruising at Days 1, 3, and 7 postoperative.
  2. Inflammation: Measured via arm circumference on Days 1, 3, and 7.
  3. Quality of Fat Samples: Pathological evaluation of fat and blood content from the lipocrit samples.

Secondary Outcome Measures

  1. Patient Satisfaction: Surveys conducted 30 days post-procedure.
  2. Complication Rates: Hematoma, seroma, and infection rates evaluated within 30 days post-op.

Safety Considerations:

Surgeons must be cautious when using cold tumescent solutions due to the risk of hypothermia, particularly during extended procedures. Continuous core temperature monitoring and the use of external warming devices are recommended to mitigate the risks of lowering core temperature.

A Phase 4 study testing Cold crystalloid infusions, 0.9%NaCl or Ringer's, Warm saline and Liposuction of the arms in people with Arm Pain and Arm Aesthetics, run by Eternal Beauty SAS at 1 site in Colombia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Colombia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ecchymosis (time frame: 7 days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06865911, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2025.
