The Marie Hanna Lab conducts research on key topics within the field of anesthesiology. Our interests include both regional and obstetric anesthesia as well as patient-controlled analgesia, pain measurement, post-operative pain and acute pain management. Examples of our work include researching whether a surgery patient’s perception of pain control affects his or her satisfaction level and a comparison of air and liquid for use in the loss-of-resistance technique during labor epidurals.
