Results
Groups 1 and 2 were similar in age and baseline preoperative variables ( Table 3 ).
Group 1 (n = 115) demonstrated a statistically significant decrease in MAP, HR, and RR in the operating room compared with the measurements in the preoperative holding area (P < .0001) ( Table 4 , Table 5 , Table 6 ).
Group 2 (n = 88) had a statistically significant increase in MAP, HR, and RR in the operating room compared with the measurements in the preoperative holding area. Significance levels were P < .0002 for MAP and P < .0001 for HR and RR ( Table 7 , Table 8 , Table 9 ).
The Figure charts the comparison of the mean values of MAP, HR, and RR between group 1 and group 2.
Individual comparisons of MAP, BP, and RR for Group I (with piano) and Group II (no piano) in holding area and in operating room.
