ObjectiveFor health professionals, the absence of pulse checked by manual palpation is a primary indicator for initiating chest compressions in patients considered to have cardiopulmonary arrest (CA). However, using a pulse check to evaluate perfusion during CA may be associated with some risks of its own. Our objective was to compare the efficiency of cardiac ultrasonography (CUSG), Doppler ultrasonography (DUSG), and manual pulse palpation methods to check the pulse in CA patients.Material And MethodsThis study was prospectively performed in 137 patients older than 16 years of age who underwent cardiopulmonary resuscitation (CPR). CUSG, DUSG, and manual pulse palpation were practiced simultaneously as suggested in the relevant guidelines. Findings of the patients were recorded at the first min, at min 15 and at the end of CPR. SPSS 18.0 was used for statistical analysis.FindingsA total of 72.3% (n = 99) of the cardiopulmonary arrest incidents occurred out-of-hospital. CUSG (4.76 ± 2.19, 4.33 ± 2.17, and 3.68 ± 2.14 s), DUSG (9.59 ± 2.37, 8.22 ± 2.86, and 7.60 ± 2.83 s), and manual pulse palpation (10.76 ± 1.03, 9.72 ± 3.01, and 9.29 ± 3.36 s) measurements of the first, second, and last inspections were detected, respectively. The false negative rates (100%, 28%, and 0%) and false positive rates (5.3%, 3.5%, and 0%) of manual pulse palpation the first, second, and last inspections were calculated, respectively, as well.ConclusionThe use of real-time CUSG during resuscitation provides a substantial contribution to the resuscitation team. CUSG will allow earlier and more accurate detection of pulse than manual pulse palpation and DUSG.Copyright © 2018 Elsevier B.V. All rights reserved.
