At the Iowa State University College of Veterinary Medicine, second year veterinary
students are taught anaesthesia by means of lectures and anaesthesia laboratories. One of
these laboratories in particular teaches the assembly and operation of the anaesthetic
machine and drug calculations for patients. The students assemble the machine, do all the
operational checks and calculate drug rates. In order to improve the students’ ability to
identify components, assemble and operate the anaesthesia machine, an Objective
Structured Clinical Examination (OSCE) was developed, that focused on thirteen critical
aspects of the process.
The OSCE was carried out by means of a Dispomed® complete unused anaesthetic machine
and a RescueCritters® intubation simulator. The thirteen areas were:
* identify anaesthetic machine components
* describe components functions
* identify breathing systems
* calculate reservoir bag size
* assemble rebreathing and non-rebreathing systems
* leak test a rebreathing and non-rebreathing system
* demonstrate gas supply knowledge * calculate fresh gas flow rates
* list breathing system differences
* calculate breathing system time constants
* describe proper intubation protocols
* demonstrate proper tracheal intubation
* demonstrate proper endotracheal tube cuff inflation
All second-year students (n=120) were examined by means of the OSCE. They were graded
on a scale from 5 (superior) to 1 (deficient). Students that scored grades of 1 and 2 were
considered unsatisfactory. Students that scored 3, 4 or 5 passed the examination. Ninety-four
percent (113/120) of students passed the OSCE. In conclusion, the highest scoring focus
areas involved mathematical calculations. The lowest scoring focus areas involved assembly
and functional operation of the machine.
