An interchangeable Mapleson A-E breathing system is practical and cost effective.
In locations where oxygen and anesthesia gas supplies are limited, and where circle systems are not practical, means to reduce fresh gas flow during maintenance of inhalational anesthesia are of potential value. We investigated whether a common transport breathing apparatus could be modified to allow interchange between Mapleson D (Map-D) and Mapleson A (Map A) configurations. ⋯ Cost and resource savings can be realized through the use of a breathing system modification that achieves appropriate ventilation at lower fresh gas flows.

Postoperative outcome among elderly patients after general anesthesia.
Preoperative decision-making for elderly patients requires a long-term perspective. The aim of this study was to identify preoperative risk factors for decreased 1- to 5-year survival rates and to compare the survival rates of stratified risk groups with those of the sex- and age-matched general population. ⋯ In patients 80 years or older who underwent surgery with general anesthesia, independent risk factors for decreased survival are male sex, dependency in daily living and abdominal surgery. Only patients independent in daily living who underwent non-abdominal surgery had survival rates comparable to those of the general population.
