Randomized Controlled Trial Clinical TrialEpidural ropivacaine for postoperative analgesia in Taiwanese patients.
Ropivacaine is the latest long-acting amide local anesthetic. As it is less cardiovasculotoxic and neurotoxic than bupivacaine it is an attractive anesthetic agent used in clinical anesthesia and postoperative analgesia. This study was undertaken to seek for a suitable dosage of ropivacaine in postoperative analgesia for Taiwanese patients whose average physicality is not entirely compatible with the pharmacopeially recommended dosage for western people. ⋯ From the results of this study, we are of the opinion that 0.125% ropivacaine could provide a postoperative analgesia in Taiwanese patients to their satisfaction with less adverse effects.

Randomized Controlled Trial Comparative Study Clinical TrialA randomized, prospective comparison of end-tidal CO2 pressure during laparoscopic cholecystectomy in low and high flow anesthetic system.
Low flow anaesthesia has been used in anesthetic practice to prevent operation room pollution and also for econormical reasons. Since the safety of low flow technique has not been clearly determined in previous researches this study was performed to compare the end-tidal CO2 pressure during laparoscopic cholecystectomy in low flow as opposed to high flow anesthesia. ⋯ The result of this study shows that end-tidal CO2 pressure during laparoscopic cholecystectomy using low flow anesthesia system is comparable to that with high flow system. Therefore it can be concluded that low flow anesthesia can be used with relative safety in anesthetic management of patients during laparoscopic cholecystectoy.

Performance evaluation of quality improvement team in an anesthesiology department.
In health care community, quality improvement pathway has always been treated as critical index to control cost, improve efficiency and promote service quality, particularly in the last decade. From theoretical standpoint, clinical practice as well as research data, quality improvement team has been demonstrated to play an important role in the adaptation to the changing health environment and enhancement of the competition through the improvement process. The purpose of this study was to explore members' job satisfaction, morale, organizational commitment and inventory management through quality improvement team intervention in a department of anesthesiology. ⋯ As other previous reports did, the present study also demonstrated that intervention of the quality improvement team improves the nurse anesthetists' job satisfaction, such as promotion of autonomy, organizational policy and positive member interaction. Moreover, it improves work efficiency, service quality as well as control of the stock inventory.

Case ReportsDelayed hypoxemia after bone cement insertion during total hip replacement under spinal anesthesia--a case report.
We report a case of delayed hypoxemia in an aged healthy male patient, which developed 2 hours after cementation of the prosthesis in total hip replacement (THR) under spinal anesthesia. The patient was doing well throughout the operation but unfortunately, progressive tachypnea was noted 1 h after he was transferred to the recovery room (i.e. 2 h after the application of bone cement into the femur). An hour further, distinct wheeze was heard bilaterally on auscultation, which signified bronchospasm. ⋯ Although wheezing soon subsided, tachypnea and desaturation persisted. He was then transferred to the surgical intensive care unit for further management. Ventilation-perfusion lung scan was performed, which was suggestive of multiple pulmonary embolism.

Fluid administration prevents renal dysfunction during hypotension under spinal anesthesia in a rat model.
Severe hypotension deteriorates renal functions and renal hemodynamics especially renal cortical blood flow. Systemic hypotension following high level spinal anesthesia may impair renal functions in spite of the blockade of renal sympathetic nerves that may help prevent vasoconstriction. Fluid loading is clinically applied for preventing hypotension but the effects on the changes of renal functions have not been studied. This study was designed to investigate the effects of fluid loading on systemic hemodynamics, renal hemodynamics and functions especially the blood distribution to renal cortex. ⋯ Fluid administration did not prevent hypotension following high level spinal anesthesia but might have beneficial effects on renal hemodynamics especially on the renal cortical circulation and urine flow rate.
