Is liquid nitrogen or Cryo Professional portable cryosurgical system the best way for clinicians to treat benign lesions or common dermatologic issues? The first consideration for any primary care practice, urgent care, or mobile clinic is choosing a treatment solution that delivers the best clinical outcomes.
Important Risk and Safety Information for Ethyl Chloride:

Published clinical trial results support the use in children 3 years of age and older. Ethyl Chloride is FLAMMABLE and should never be used in the presence of an open flame or electrical cautery equipment. Use in a well-ventilated area. Intentional misuse by deliberately concentrating or inhaling the contents can be harmful or fatal. Do not spray in eyes. Over-application of the product may lead to frostbite and/or altered skin pigmentation. Cutaneous sensitization may occur, but appears to be extremely rare. CAUTION: Federal law restricts this device to sale by or on the order of a licensed healthcare practitioner.

Important Risk and Safety Information for PainEase:

Consult your pediatrician when using on children 4 years old and younger. Do not use on large areas of damaged skin, puncture wounds, animal bites, or serious wounds. Do not spray in eyes. Over-spraying may cause frostbite. Freezing may alter skin pigmentation. Use caution when using product on persons with poor circulation. Apply only to intact oral mucous membranes. Do not use on genital mucous membranes. The thawing process may be painful and freezing may lower resistance to infection and delay healing. If skin irritation develops, discontinue use. CAUTION: Federal law restricts this device to sale by or on the order of a licensed healthcare practitioner.

Important Risk and Safety Information for Cryo Professional:

Cryo Professional is FLAMMABLE. Keep away from open flame and other potential ignition sources, including diathermy or other medical equipment. Use in a well-ventilated area. Consult a pediatrician for use on patients 4 and younger. Do not use if uncertain of diagnosis or if there is a possibility of cancer, or on patients with cryoglobulinemia, circulatory issues, or patients using immunosuppressant medication. Do not spray cryogen directly on skin or when applicator tip is in contact with skin. Avoid eye contact. Use only as a system with the supplied applicators. Freezing may alter skin pigmentation. Avoid freezing on peripheral arteries. Carefully read instructions prior to using this product. CAUTION: Federal law restricts this device to sale by and on the order of a licensed healthcare practitioner.

Is liquid nitrogen or Cryo Professional portable cryosurgical system the best way for clinicians to treat benign lesions or common dermatologic issues? The first consideration for any primary care practice, urgent care, or mobile clinic is choosing a treatment solution that delivers the best clinical outcomes.

Since time, space, and cost are always considerations, the right solution must also be easy to use, portable, and affordable.

This means understanding how both solutions meet clinical efficacy, workflow, storage constraints, staff training, and operational overhead demands.

h2 - Clinical Efficacy and Portability in Practice

(hyperlink example) Studies indicate dimethyl ether and propane and liquid nitrogen have no clinically relevant differences in efficacy when treating benign lesions.

Cryo Professional meets the portability and safety needs of every practice because:

  • It uses a DMEP blend delivered via a handheld, self-contained aerosol with no need for tanks or cords
  • There is no need for refrigeration or special storage requirements, so practices can store it like any other Class II medical device
  • Treatment application is precise, quiet, and non-intimidating for children and nervous adult patients

Whether you’re treating in a clinic, a satellite office, or a standard outpatient suite, this system travels well and delivers consistent results.

h3 - Safe for Patients, Smart for Staff

DMEP systems have a strong safety record and avoid the risks of liquid nitrogen or nitrous oxide cryosurgery. The Cryo Professional system uses dimethyl ether and propane making it safer to store and handle, especially in facilities that restrict gas storage. The aerosol spray-control design makes it ideal for use across a range of skin types, lesion sizes, patient ages, and clinical settings.

h4 - Safe for Patients, Smart for Staff

DMEP systems have a strong safety record and avoid the risks of liquid nitrogen or nitrous oxide cryosurgery. The Cryo Professional system uses dimethyl ether and propane making it safer to store and handle, especially in facilities that restrict gas storage. The aerosol spray-control design makes it ideal for use across a range of skin types, lesion sizes, patient ages, and clinical settings.

h5 - Safe for Patients, Smart for Staff

h2 - IMPORTANT RISK AND SAFETY INFORMATION:

Cryo Professional is FLAMMABLE. Keep away from open flame and other potential ignition sources including diathermy or other medical equipment. Use in a well-ventilated area. Consult a pediatrician before use on patients 4 years old and younger. Do not use if uncertain of diagnosis or if there is a possibility of cancer, or on patients with cryoglobulinemia, circulatory issues, or using immunosuppressant medication.
