Central Venous Cannulation and Arterial Line placement
Frequency of central venous cannulation (CVC) was assessed, with 11
individuals performing over 25 cases in the last year, 6 performing
between 0 and 5, and 3 performing between 6 and 10 as well as between 11
and 25 cases (Table 2) . Twelve trainees reported that they were
taught CVC placement from a senior resident, and the rest were taught by
an attending (52.2% vs 47.8%). There was a significant increase in the
standardization of CVC placement (4.17 vs 4.74, p=0.008) as well as
trainee confidence to successfully place an CVC (4.3 vs 4.70, p=0.046)
(Figure 1) . Thirteen trainees had performed over 25 radial
arterial lines and 12 trainees had performed over 25 femoral lines. The
rest of the trainees were similarly distributed with 4 individuals
having between 0 and 5 radial and femoral lines, 3 trainees having
between 6 and 10 radial lines while 4 had between 6 and 10 femoral line
placements. Three trainees had between 11 and 25 radial and femoral line
placements. The instructors for arterial line placements were evenly
split, with 13 trainees being taught by a senior resident and 13 being
taught by an attending. There was a significant increase after the
course in the Likert scores for standardization of arterial line
placement (4.09 vs 4.63, p=0.01) as well as the residents perceived
ability to place an arterial line (4.22 vs 4.68, p=0.02).
