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.

Case ReportsPostoperative pulmonary edema, transfusion-related?--a case report.
Transfusion-related acute lung injury (TRALI) is a severe reaction between leukocyte antigen and antibody during transfusion of plasma-containing components. Recently, biologically active lipids have been also suggested to cause the disorder. It is a rare, but rather benign pulmonary edema. ⋯ Because the patient received blood products from 3 or 4 donors and the disorder was not recognized right away, the laboratory task for the definite diagnosis was difficult. Nevertheless, the patient had fully recovered in 36 hours after supportive therapies. Without identifying the blood donor implicated in the disorder, transfusion reactions or TRALI will be inevitable.

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.

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.
