Summary
Brief summary
For surgical cases with general anesthesia, components of nonsurgical operating room (OR) time include induction (arrival of patient in the OR until the start of positioning), extubation (dressing on patient to extubation), and OR exit. The interval between the end of surgery and extubation (emergence time) is of special interest to anesthesia care providers and companies because it is affected by anesthetic agents. In Taiwan, a new system of Diagnosis Related Groups (DRG) has taken its part in hospital billing service since 2010. This means that the previous billing system will not be valid for current anesthesia cost in the OR any more. Instead, one sum payment one case, selection of the anesthetic technique has to be determined: cheaper agents and least possible anesthesia-controlled time to remain competitive in the operating field.
Total intravenous anesthesia (TIVA) via target controlled infusion (TCI) system incorporating the combined use of propofol and remifentanil has indeed been shown to provide more rapid emergence than other anesthesia techniques. In our previous study, we found patients undergoing prolonged procedure recover faster after TIVA than after volatile anesthesia. To evaluate potential resources for reducing time in the OR, we performed a retrospective study to compare anesthesia-related times following ophthalmology (OPH) surgery in adult patients who received different anesthesia techniques, TIVA with propofol or desflurane anesthesia.
