Rc. Prielipp et al., USE OF ESOPHAGEAL OR PRECORDIAL STETHOSCOPES BY ANESTHESIA PROVIDERS - ARE WE LISTENING TO OUR PATIENTS, Journal of clinical anesthesia, 7(5), 1995, pp. 367-372
Study Objective: To ascertain current anesthesia utilization of esopha
geal and precordial stethoscopes in U.S. anesthesia training programs.
Design: Prospective, single-blind, incidence study. Setting: Operatin
g rooms of three tertiary care hospitals with major academic anesthesi
ology departments. Subjects: Anesthesia faculty [MD and certified regi
stered nurse-anesthetist (CRNA) staff] and anesthesia trainees (anesth
esiology residents and student nurse-anesthetists). Interventions: Obs
erve and record the placement (stethoscope device appropriately positi
oned) and utilization (stethoscope in place and connected to the ear p
iece of the anesthesia provider) of the esophageal or precordial steth
oscope during general, regional, and monitored anesthesia care. Measur
ements and Main Results: During 520 anesthetics, an esophageal stethos
cope was inserted in 68% of subjects, a precordial stethoscope was pos
itioned in 16%, and an anesthetic stethoscope was absent in 16% of cas
es. Utilization (stethoscope connected to earpiece) ranged from a low
of 11% of cases to a high of 45%, depending on the institution Overall
, providers were listening via an, anesthetic stethoscope in only 28%
of anesthetics. Conclusions: Our data suggest infrequent utilization,
of esophageal and precordial stethoscopes in anesthesia training insti
tutions. Thus, current anesthesia training may be fostering an environ
ment where providers overlook a valuable minimally invasive, and cost-
effective continuous monitor of patients' dynamic vital organ function
.
