Whether it is the eradication of biofilm or treating wounds in locations not conducive to sharp debridement, ultrasonic debridement can be a key tool for promoting improved wound healing.The surgical debridement of nonviable tissue is essential in the wound care process. While sharp debridement with or without pulse lavage is the most common method, the use of an ultrasonic wound debridement machine is a more recent option that one should consider. Physicians originally developed ultrasonic debridement for dentistry in the 1950s and later adapted it for debulking soft tissue and dissecting bone.
Forget about the hassle of ice packs, cold therapy machines are the easiest, most effective way to apply for continuous relief from joint pain and swelling and inflammation. Whether you’re recovering from surgery, recovering from a workout, or simply seeking relief from a painful medical condition, a cold therapy machine can help speed your recovery and ease the pain.
Studies in the early 1970s suggested that wrapped sterilization trays remained sterile for varying periods depending on the type of material used to wrap the trays. Microorganisms were found to penetrate single-wrap muslin as early as three days, and double-wrap muslin and single-wrap two-way crepe paper in 21 to 28 days when stored on open shelves. Based on these studies, the Joint Commission on Accreditation of Hospitals (now Joint Commission of Healthcare Organizations) required that hospitals provide an expiration date on wrapped surgical trays, indicating a time when the trays would no longer be considered sterile. In a 1984 article, Mayworm criticized the scientific basis for dating sterile surgical trays. He noted that "time doesn't contaminate products, events do." He then listed the following factors, which contribute to the contamination of product: bioburden (contamination in the environment), air movement, traffic, location, temperature, humidity, and the barrier properties of the wrap material. He stressed that when the proper wrap materials along with appropriate sterilization techniques were used, surgical trays should remain sterile unless damaged. Subsequent studies demonstrated that the sterile integrity of surgical packs was maintained for at least one year and no trend was found toward increased probability of contamination over time. In this latter study, no differences were observed among the wrapping materials studied (i.e., two-ply reusable, nonbarrier wovens, both new and previously used; disposable, barrier nonwovens; and paper/plastic peel pouches). These studies were conducted under ideal circumstances. Sterility may be more difficult to maintain under actual use conditions where movement and storage conditions may damage wrap materials. |
