The Impact of Dry Versus Moist Heat
P eripheral IV catheter insertion is a common nursing procedure often required for the administration of chemotherapy, antibiotics, blood products, fluids, and other medical therapies in hematologic patients with cancer. Although necessary and usually brief, IV insertion often is a source of patient anxiety and discomfort and can be extremely difficult to achieve, particularly in individuals re...
متن کاملInactivation of Cryptosporidium parvum Oocysts by Ammonia.
The survival of Cryptosporidium parvum oocysts in soil and water microhabitats may be affected by the environmental production and release of free ammonia. The objective of this study was to determine the effects of increasing free ammonia concentrations and times of exposure on oocyst viability. Wild-type oocysts were obtained from naturally infected calf feces by chemical (continuous-flow) ce...
متن کاملMoist Heat or Dry Heat for Delayed Onset Muscle Soreness
BACKGROUND Heat is commonly used in physical therapy following exercise induced delayed onset muscle soreness (DOMS). Most heat modalities used in a clinical setting for DOMS are only applied for 5 to 20 minutes. This minimal heat exposure causes little, if any, change in deep tissue temperature. For this reason, long duration dry chemical heat packs are used at home to slowly and safely warm t...
متن کاملHow moist heat kills spores of Bacillus subtilis.
Populations of Bacillus subtilis spores in which 90 to 99.9% of the spores had been killed by moist heat gave only two fractions on equilibrium density gradient centrifugation: a fraction comprised of less dense spores that had lost their dipicolinic acid (DPA), undergone significant protein denaturation, and were all dead and a fraction with the same higher density as that of unheated spores. ...
متن کاملEfficacy of chlorine dioxide tablets on inactivation of cryptosporidium oocysts.
The ability of chlorine dioxide (ClO2) to achieve 2-log inactivation of Cryptosporidium in drinking water has been documented. No studies have specifically addressed the effects of ClO2 on C. parvum oocyst infectivity in chlorinated recreational water venues (e.g., pools). The aim of this research was to determine the efficacy of ClO2 as an alternative to existing hyperchlorination protocols th...
