Is Pain Ease (New Formula) Safe and Effective in Reducing Pain Associated With Peripheral Intravenous Cannulation (PIV)?

September 10, 2026 updated by: Gebauer Company

Prospective, Randomized, Double-Blinded, Comparative Efficacy Safety and Microbial Limits Clinical Trial of Gebauer's Pain Ease (New Formula) Instant Topical Anesthetic Spray for Peripheral Intravenous Cannulation

The goal of this clinical trial is to learn if Pain Ease (new formula) is more effective than Nature's Tears in reducing pain associated with Peripheral Intravenous Cannulation (PIV), also known as an IV. This clinical trial will also learn if Pain Ease (new formula) increases the germs at the application site. The main questions it aims to answer are:

  1. Will Pain Ease (new formula) reduce the amount of pain when receiving an IV?
  2. Will the microbes increase when Pain Ease (new formula) is applied on cleansed skin?

Participants will:

  1. Either have Pain Ease (new formula) or Nature's Tears sprayed on the skin prior to receiving an IV
  2. Complete questionnaires on how the experience was
  3. Complete the study within 60 minutes after the application of either spray, if no reactions occur

Study Overview

Detailed Description

The primary objective of the study is to demonstrate the superiority of Pain Ease (new formula) versus placebo (Nature's Tears) in reducing pain associated with PIV cannulation. Additionally, the study aims to evaluate the microbial limits of Pain Ease (new formula) by evaluating the number of viable microbes detected on the PIV site when applying Pain Ease (new formula) after Chlorhexidine Gluconate (CHG) cleaning compared to CHG cleaning only. The secondary objective of the study is to evaluate the success rate of PIV cannulation and satisfaction of treated subjects and healthcare providers with Pain Ease (new formula) or placebo.

Description

Inclusion Criteria:

  • Patients needing peripheral intravenous (PIV) cannulation.
  • Adults aged 18 to 75 years.
  • Mentally competent patients able to understand the consent.

Exclusion Criteria:

  • Patients with any allergies to the spray components (e.g., 1-chloro-3,3,3-trifluoro-1-propene or 1,3,3,3-Tetrafluoropropene).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: To study safety and efficacy
Pain Ease (new formula, P/N 0386-0008-13) hereafter referred to as "Pain Ease (new formula)" is a blend of high purity hydrofluoroolefins (HFO)-1233zd (1-Chloro-3,3,3-trifluoroprop-1-ene) and high purity HFO-1234ze (1,3,3,3-Tetrafluoroprop-1-ene). Pain Ease (new formula) is contained in an aerosol packaging consisting of a lined aluminum can, coated aluminum-cup valve with an elastomer stem gasket, plastic dip tube, and a plastic actuator.
The vapocoolant spray is a blend of high purity hydrofluoroolefins (HFO)-1233zd (1-Chloro-3,3,3-trifluoroprop-1-ene) and high purity HFO-1234ze (1,3,3,3-Tetrafluoroprop-1-ene). The vapocoolant is contained in an aerosol packaging consisting of a lined aluminum can, coated aluminum-cup valve with an elastomer stem gasket, plastic dip tube, and a plastic actuator.
Placebo Comparator: To study microbial limits
Nature's Tears Eye Mist® 3 oz can is sterile water, preservative and chemical free, and non-allergenic. Nature's Tears Eye Mist® 3 oz can is contained in an aerosol packaging consisting of an aluminum can which size and nozzle are comparable to Pain Ease (new formula) package.
The sterile water is preservative and chemical free, and non-allergenic. The sterile water can is contained in an aerosol packaging consisting of an aluminum can which size and nozzle are comparable to Pain Ease (new formula) package.
