Acoustical evaluation of auscultatory sounds by auscultation sites in pediatric anesthesia patients - Auscultatory sounds during pediatric anesthesia

The auscultation sound scores are shown in Figure 1. The lung sound score at Sites A,B and C were 8.0 (7.0-9.0), 4.5 (2.9-6.0) and 7.0 (5.5-8.5), respectively (Figure 1b). The heart sound scores at Site A, B and C were 3.5 (2.0-6.0), 6.5 (4.0-8.0) and, 1.0 (0.4-2.0) respectively (Figure 1c). Statistically significant differences were found in all pairs of sites (p<0.0001 except for Site A vs. C of the lung sound [p=0.0107] and Site A vs. B of the heart sound [p=0.0018]).
