The Patient and Observer Scar Assessment Scale (POSAS) is a questionnaire that was developed to assess scar quality. It consists of two separate six-item scales (Observer Scale and Patient Scale), both of which are scored on a 10-point rating scale. After many years of experience with this scale in burn scar assessment, it is appropriate to examine its psychometric properties using Rasch analysis. ⋯ The Rasch model demonstrated that the POSAS is a reliable and valid scale that measures the single-construct scar quality.

PolyMem(®) Wic(®) Silver(®) Rope: A Multifunctional Dressing for Decreasing Pain, Swelling, and Inflammation.
Choosing the most appropriate dressing to meet the complex needs of patients with narrow deep wounds, such as tunnels, fistulas, and cysts, is a daunting task. Such wounds are difficult to cleanse and tend to be extremely painful. Wound patients need a drug-free dressing that handles exudates, decreases the need for traumatic cleansing during dressing changes, and addresses wound pain, inflammation, and swelling. ⋯ PolyMem dressings enhance autolytic debridement, which often results in production of large quantities of pale yellow enzyme- and nutrient-rich wound fluid during the first treatment week. Extra-absorbent PolyMem Max secondary dressings can contain excess fluid.

Incidence of unanticipated difficult airway in obstetric patients in a teaching institution.
Airway experience was analyzed among patients who had pregnancy-related surgery under general anesthesia from January 2001 through February 2006. A difficult airway was defined as needing three or more direct laryngoscopy (DL) attempts, use of the additional airway equipment after the DL attempts, or conversion to regional anesthesia due to inability to intubate. Airway characteristics were compared between patients with and without a difficult airway. In addition, pre- and postoperative airway evaluations were compared to identify factors closely related to changes from pregnancy. ⋯ Unanticipated difficult airways accounted for 0.56% of all pregnancy-related surgical patients. More than 99.9% of all obstetric patients could be intubated. A difficult airway is more likely to be encountered by anesthesia providers with <1 year of experience. Proper use of airway equipment may help secure the obstetric airway or provide adequate ventilation. Emergency CD did not add an additional level of difficulty over nonemergency CD.
