Clinical Study on Implant Survival and Graft Resorption Rate After Maxillary Sinus Bone Grafting

Methods for Differentiation of the CSF and Local Anesthetics during Combined Spinal Epidural Anesthesia: A case report / 대한마취과학회지

Combined spinal epidural block with use of the needle-through-needle technique has become increasingly more popular during recent years because it provides rapidity and density of spinal block, combined with the ability to extend the block and provide postoperative analgesia by use of the extradural catheter. However, the combined spinal epidural block has some disadvantages. Since the spinal needle makes a hole in the dura, the accidental migration of an extradural catheter into the dural opening made previously by the spinal needle is thought to be theoretical risk. We report a case during combined spinal epidural anesthesia for a total hip replacement in which the clear fluid in the epidural catheter was found and tested to confirm the nature of fluid and migration of catheter by the dextrostix test and the immunoelectrophoresis test(prealbumin test).

A Study of the Usefluness of Forced Expiratory Spirometry as a Preoperative Laboratory Screeing in the Elderly Patient / 대한마취과학회지

BACKGROUND: Preoperative screening laboratory tests including forced expiratory spirometry (FES) are performed either to determine the progress of a known disease or to detect unsuspected abnormalities in asymptomatic patients. The former is generally accepted, while there is often dispute about the latter indication. But the routine ordering of preoperative screening tests is currently common practice. Age is used as a criterion to select preoperative tests for asymptomatic elderly patinets. FES and arterial blood gas analysis (ABGA) are used currently as a preoperative screening test. The objective of the present study is to assess the value of FES and ABGA as a preoperative screening test in elderly patients undergonig surgery. METHODS: We have done a retrospective review of the medical records to assess the value of FES and ABGA as a routine preoperative screening tests in 94 asymptomatic elderly patients (> or = 65 years) undergoing surgery within 6 months recently. RESULTS: A retrospective review of the medical records was that the results of FES revealed the stage of early aymptomatic obstructive pulmonary disease and those of ABGA were within lower normal limit. CONCLUSIONS: The present study confirms the forced expiratory spirometry is a valuable preoperative screening test in the elderly patients with clinial assessment during the preanesthetic visit.
