ABSTRACT
OBJECTIVES:
Physical examination can identify palpable splenomegaly easily, but evaluating lesser degrees of splenomegaly is problematic. Hand-carried ultrasound allows rapid bedside assessment of patients. We conducted this study to determine whether hand-carried ultrasound can reliably assess spleen size.METHODS:
Patients with varying degrees of splenomegaly were studied. Two sonographers blindly measured spleen size in each patient using either a hand-carried or conventional ultrasound device in random order. Sonographers completed a data sheet indicating the adequacy of the image, clinical measurements of enlargement, and confidence in their observations.RESULTS:
Sixteen patients (10 male and 6 female; mean age ± SEM, 60 ± 4 years) were recruited. Image quality was adequate or better in all scans with conventional ultrasound and in 15 of 16 scans with hand-carried ultrasound. The greatest longitudinal measurement recorded was statistically equivalent across ultrasound techniques, with mean values of 16.4 cm (95% confidence interval, 14.8-18.0 cm) for conventional ultrasound and 15.8 cm (95% confidence interval, 14.1-17.4 cm) for hand-carried ultrasound. The correlation between measurement techniques was r = 0.89 (P < .0001). Sonographers were somewhat or very confident in the outcomes of all scans with conventional ultrasound and in 15 of 16 cases with hand-carried ultrasound. In general, it took longer for sonographers to obtain images with hand-carried ultrasound.CONCLUSIONS:
We have shown that hand-carried ultrasound can be used at the point of care by trained individuals to diagnose splenomegaly. However, hand-carried ultrasound images were less likely to be judged excellent, were accompanied by less diagnostic certainty, and took longer to obtain.Palavras-chave
