Keeping It Sterile Using Bioburden Counts

Keeping It Sterile Using Bioburden Counts Bob Michaels | Jun 03 2014 For information on sterility assurance levels (SALs) see How Can You Ensure that Your Device Is Sterile? When sterilizing medical devices sterilization personnel rely on bioburden counts as part of determining and maintaining the sterilization process In the following QA Martell Winters senior scientist at Nelson

Current preventive measures for health

Healthcare-associated infections (HAIs) continue to be a tremendous issue today It is estimated 1 7 million HAIs occur per year and cost the healthcare system up to $45 billion annually Surgical site infections (SSIs) alone account for 290 000 of total HAIs and approximately 8 000 deaths In today's rapidly changing world of medicine it is ever important to remain cognizant of this matter

The use of enzymatic products should start during the pre-cleaning process at the point of use immediately following procedures Enzymatic foams gels and humectants designed for pre-cleaning aid in loosening soils and keeping instruments moist pending further cleaning until reprocessing begins This discourages soils from drying and forming biofilms After the instruments are transported to

Sterile Products: Advances and Challenges in Formulation

As a process control component bioburden testing is part of the overall quality system for sterile production Components of a parenteral drug solution should be tested as necessary to assure they are not adding an excessive microbial load to the bulk And since the most common component of a parenteral product is water for injection (WFI) it seems reasonable that the other components would

Summary of Procedures Currently Used to Assess

As with the aforementioned methods these involve the use of specific collection materials (cotton swabs or sterile cloths) to sample surfaces followed by immersion of the sampling material in a solution and then sonication subsampling and incubation on petri plates under specified conditions and times Plates are scanned for growth at appropriate intervals and results are expressed as

Water Treatment for Hemodialysis: What You Must Know

Total viable counts must be obtained using the membrane filter technique (where a known volume of water is filtered through a membrane and the membrane is then aseptically transferred to an agar plate) or the spread plate technique (an inoculum of at least 0 1 to 0 3 mL of sample is spread over the agar) Use of a calibrated loop to apply the sample is prohibited this method is not sensitive

Skin Grafting Techniques for Open Diabetic Foot Wounds

Skin graft healing proceeds through a series of phases unique to transplantation of skin (12–16) The initial phase is termed the phase of serum imbibition or "plasmatic circulation" and is an ischemic phase that occurs during the first 24 hours following graft application () During this stage fibrin glue anchors the graft to the recipient bed allowing the graft to passively absorb

Science of Infection Control Principles

Sterile supplies should be separated from non-sterile supplies by a functional barrier such as a drawer bin or shelf This practice prevents the excessive handling of sterile supplies in order to reach non-sterile supplies and minimizes the chances that a non-sterile item will be selected for use when a sterile item is needed Access to storage areas should be restricted to minimize traffic

The acceptable terminal sterilization bioburden level was derived from the Viking pre-sterilization level of 3 10 5 spores per vehicle which was reduced after bake-out by four orders of magnitude to a calculated value of 30 spores per vehicle Such an approach using heat treatment is clearly impracticable in general for Antarctic sampling at present although it may prove possible to apply
