Intraoperative ultrasound of the liver. An important adjunctive tool for decision making in the operating room.

Forty-nine patients operated on for liver or other pathologic processes were examined intraoperatively with special ultrasound transducers during surgical exploration of the abdomen. Subjects were evaluated because of known or suspected disease of the liver. All patients were examined using sterile technique. Prospective diagnosis and retrospective analysis of data were used. In 55% of subjects, no new information was obtained. In 19%, new information was gathered that changed the surgical approach. In 14% of patients, new information was obtained but it was such that no change in the therapeutic approach was needed. In 12% of patients, although no new information was gathered by the use of intraoperative ultrasound, a change in the surgical approach and management of the patient was still possible because of intraoperative ultrasound. These studies show that the routine use of ultrasound during intraoperative procedures, particularly when involving hepatic structures, is a clinically useful technique. In many instances, it will change the course of management.

Relative value guide basic units in operating room scheduling to ensure compliance with anesthesia group policies for surgical procedures performed at each anesthetizing location.

Many anesthesia groups provide services in a spectrum of anesthetizing locations, including offices, free-standing ambulatory surgery centers, diagnostic clinics, and traditional hospital operating rooms. The use of a uniformly understood measure of case complexity could assist an anesthesia group in ensuring appropriate anesthesia provider expertise and equipment availability at each anesthetizing location. In this article, we show how the American Society of Anesthesiologists' Relative Value Guide (ASA RVG) basic units can be used as a criterion to establish the maximum level of complexity of cases performed at each location by an anesthesia group. By reviewing ASA RVG basic units at several anesthetizing locations in lowa, we found that ASA RVG basic units differ among sites. The ASA RVG basic units can be used to identify cases that are seemingly unexpected for an anesthetizing location. There are several reasonable values that an anesthesia group can use for its maximum number of basic units at an anesthetizing location.
