conclusions both dexmedetomidine and esmolol can be used as agents to control hypotension in patients undergoing lumbar spine decompression and fixation surgery; the dexmedetomidine group, however, was associated with better intraoperative hemodynamic stability and reduced intraoperative analgesic and volatile anaesthetic requirement. results the study results showed that dexmedetomidine had lo...

Background: The touch preparation technique is an accurate and rapid method, and when used as intraoperative consultation examination technique it preserves a good amount of tissue for paraffin embedded sections. This study aimed at examining the accuracy of the touch preparation technique by comparing its diagnosis with that of final pathological diagnosis made by microscopic examinations. ...

Ten patients with prior spinal cord trauma were examined preoperatively by metrizamide computed tomography (CT) and were studied subsequently by intraoperative spinal sonography. On comparing intraoperative sonography with metrizamide CT, it was found that metrizamide CT tends to overestimate the size and number of posttraumatic cysts, that areas of myelomalacia on metrizamide CT correspond to ...

PURPOSE To compare single-site intraoperative sarcomere length values with sarcomere lengths measured from systematic sampling of the entire transferred muscle. METHODS The tendon of the rabbit second toe extensor muscle was transposed to the ankle extensor retinaculum under levels of stretch over the sarcomere length range of about 2.5 microm to about 4.0 microm. Intraoperative sarcomere len...

OBJECTIVES To compare surgeons' interpretations of intraoperative diagnoses with those rendered by the pathologist. METHODS Consecutive intraoperative diagnoses over a nine-month period were retrospectively reviewed. For each case, operative notes were obtained from the hospital information system. The intraoperative diagnoses listed in the final pathology reports were compared with those dic...

BACKGROUND Parathyroid lipoadenoma is an uncommon tumor that may be difficult to diagnose on intraoperative frozen section. Intraoperative parathyroid hormone (PTH) measurement is useful in assessing the adequacy of parathyroidectomy. This case demonstrates the value of intraoperative PTH measurement in recognizing a parathyroid lipoadenoma. METHODS AND RESULTS A case of a 62-year-old woman w...
