Informative imaging of multiple parameters for the practice of the anesthesiologist.

The development of informative design principles is necessary to permit logical, informative and understandable computer-aided imaging of the flood of measured parameters the practising anesthesiologist is currently confronted with. The computer-assisted workplace, furthermore, can use the computer to close the loop from sensor to therapy through software directed feed back control mechanisms. The general principles of information design should be based on the rule of three derived from the limited visual integration capacity of the human brain. Thus multiple parameters should be logically grouped in blocks of three strictly distinct from each other in the visual display output. Alarm signalisations have to include two senses: visual and audible and should use the large range of variability that is possible to make them distinct from each other. The operational keyboard should be logically designed with grouping in three parts: 1. a group of buttons for activation of operational screen information that appear with never more than three at the same time; 2. buttons for presetting of wanted parameter values, of alarm limits and for introduction of patient data with adjoint but strictly separated OK-mode necessity to alert that change is being made. 3. a row of buttons separated from the normal operational keyboard area for emergency changes and computer feed back mode bypass, for example. The most illogical, unoverseeable and confusing computeraided workplace can be organized to a fully assisting anesthesia workplace if proper design is applied. The use of a users' manual should be rendered unnecessary even to a computer-naive user. This can be achieved through adequate informative design and operational information flow.(ABSTRACT TRUNCATED AT 250 WORDS)

Renal transplantation in a developing country: anesthesia and other considerations.

The Renal Transplant Team at Tulane University Medical Center has been involved in training a multispecialty group of Guatemalan physicians to perform renal transplantations in Guatemala. The purpose is to train the physicians in their own country, using available equipment and personnel so that they can perform successful operations in our absence. This paper is a review of the considerations involved in the initial renal transplantation done in Guatemala by the Tulane Renal Transplant Team. The need for a preliminary site visit was paramount. Personnel, facilities, and both surgical and anesthesia equipment and supplies were carefully evaluated. The recipient was a 22-year-old man with end-stage renal disease due to chronic glomerulonephritis. The donor was a healthy 33-year-old brother. This article is not intended to review renal transplantation in the United States, but to show what is feasible in a developing country where many drugs and equipment are not available.
