Abstract

The pain from insertion of two small cannulae was compared in 26 volunteers. Each subject was blindfolded and had both a 22 G and a 20 G cannula inserted in random order. One subject was rejected as cannulation was unsuccessful. Of the remaining 25 subjects, 12 found the 22 G more painful and 13 the 20 G. This difference was not significant (chi squared p > 0.1).
