    Study Notes

    Early Stethoscope Use in Anesthesia

    • Robert Kirk (1896) first documented operating room auscultation using a modified stethoscope.
    • Charles K. Teter praised the stethoscope's ability to provide continuous information on heart and respiratory changes, aiding in the prevention of complications.
    • He specifically highlighted the convenience of the flat Kehler stethoscope.

    Blood Pressure Monitoring

    • Harvey Cushing's advocacy for continuous cardiac and respiratory monitoring during anesthesia led to widespread intraoperative auscultation.
    • Cushing's introduction of Riva-Rocci's sphygmomanometer allowed for blood pressure monitoring during anesthesia, initially only systolic pressure due to the radial pulse palpation method. Early cuffs were inaccurate due to design limitations.
    • The development of ultrasound in the 1940s enabled Doppler-based blood flow detection and improved blood pressure measurement, particularly in infants (Arteriosonde).
    • Automated devices like the Dinamap improved the ease and speed of non-invasive blood pressure monitoring.

    Early Anesthesia Monitoring Practices

    • The death of Hannah Greener (1848) highlighted the significance of monitoring vital signs (respiration, pulse, skin color) during anesthesia.
    • Joseph Clover (1864) stressed the importance of continuous pulse observation during anesthesia, recommending cessation of anesthetic if irregularities were detected.
    • Robert Codman (1894), influenced by F.B. Harrigan, encouraged pulse recording during anesthesia. Cushing's 1902 publication of actual patient records further supported this practice. However, some opposed new monitoring devices, fearing the degradation of clinical skills.

    Negligence and Standard of Care

    • Negligent acts in anesthesia care can be acts of commission (doing something wrong) or omission (failing to do something).
    • The "reasonably prudent professional" standard provides an objective measure for evaluating actions within the scope of the individual's training, license, and professional standards.
    • Demonstrating adherence to a standard of care helps reduce the likelihood of malpractice claims.
