Study summary

The aim of this study is to test the effect of Hyperbaric Oxygen Therapy) HBOT (100% oxygen; 2.0 ATA; 90 minute total exposure) and compare against a hyperbaric sham treatment (HBST) (patient's breathing room air; 2.0 ATA; 90 minute exposure) in reducing edema and ecchymosis. HBOT will be applied as a single pre-operative and a single post-operative treatment for patients undergoing eyelid surgery. Briefly, patients will be exposed to HBOT 2-4 hours prior to undergoing surgery, 2-4 hours post-surgery and healing will be assessed at day 3, 10, 21, 30 \& 90 days after surgery. Edema and ecchymosis will be assessed in a time series to determine the extent that HBOT reduces these clinical signs. The primary null hypothesis to test will be that no differences in scores will exist between treatment and control at day 3, 10 \& 21 post-surgery. A secondary null hypothesis to test is the time required to change a score will be no different between the two groups.

HBOT=hyperbaric oxygen therapy; HBST=hyperbaric sham treatment

Inclusion criteria

  • Patients that are able to undergo surgery at the Allure Clinic are capable of undergoing exposure to HBOT, as the of HBOT are similar to eyelid surgery, with few exceptions.

Exclusion criteria

Exclusion Criteria:

  • The investigators will exclude active smokers and those who have quit smoking in the last 12 months, those with known lung disease, seizure disorder, congestive heart failure, known active cancer, previous treatment with specific chemotherapy agents (Doxorubicin, Bleomycin, Disulfiram, Cis-platinum, Mafenide acetate), those who cannot undergo pressurization/ depressurization because of eustachian-tube dysfunction and confinement anxiety.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    Hyperbaric oxygen therapy

    We propose to study the effects of two HBOT treatments (one before and one after surgery) with patients who have undergone upper eyelid surgery. Reduction in swelling and bruising will be assessed at 3, 10, 21, 30 and 90 days post-surgery to determine if healing is accelerated by HBOT. Patients that volunteer to participate in this study will be exposed to two treatments of 100% oxygen at 2.0 atmospheres absolute (ATA) or air (sham) 1.2 ATA inside mono-place chambers for 90 minutes. By comparing oxygen treatment groups with a matched control group, we can accurately assess the effectiveness of this treatment for patients. By participating in this study, patients will help in establishing the best treatment practices of using HBOT to accelerate healing and reduce cost in surgical recovery.

What researchers measure

Primary outcomes

  1. A measureable reduction of ecchymosis grade in treatment group vs. control group

    Ecchymosis will be assessed in a time series to determine the extent that HBOT reduces these clinical signs. The primary null hypothesis to test will be that no differences in scores will exist between treatment and control at day 3, 10 \& 21 post-surgery.

    Time frame: 21 days

Secondary outcomes

  1. A measureable reduction of edema grade in treatment group vs. control group

    Edema will be assessed in a time series to determine the extent that HBOT reduces these clinical signs. The primary null hypothesis to test will be that no differences in scores will exist between treatment and control at day 3, 10 \& 21 post-surgery.

    Time frame: 21 days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 5, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
