Randomized Controlled Trial Clinical TrialEffects of intravenous ketorolac and fentanyl combined with midazolam on analgesia and side effects during extracorporeal shock wave lithotripsy.
Extracorporeal shock wave lithotripsy (ESWL) is usually carried out on ambulatory or outpatient basis, and thus an appropriate anesthesia with minimal side effects is required. This study was to compare the analgesic and side effects of intravenous ketorolac with that of intravenous fentanyl, in combination with midazolam in ESWL. ⋯ Both intravenous ketorolac and fentanyl in combination with midazolam could provide good anesthesia for ESWL. However, ketorolac plus midazolam had less side effects and allowed shorter discharge time from PAR. We suggest that intravenous ketorolac combined with midazolam is a safe and effective anesthetic regiment for ESWL, particularly on ambulatory basis.

Randomized Controlled Trial Comparative Study Clinical TrialA comparative study of the safety and efficacy of 0.5% levobupivacaine and 0.5% bupivacaine for epidural anesthesia in subjects undergoing elective caesarean section.
Levobupivacaine is the S(-)-enantiomer of the racemic bupivacaine. Data of pharmacological studies suggest that levobupivacaine has a lower potential of toxicity for central nervous and cardiovascular systems than does bupivacaine. The present study was undertaken to compare the safety and efficacy between levobupivacaine and bupivacaine in epidural anesthesia for Cesarean delivery. ⋯ The onset and fade-out of sensory and motor blockade, quality of anesthesia, muscle relaxation and overall quality of anesthesia as assessed were comparable between two groups. No significant maternal or neonatal adverse events were found between the treatment groups. In comparison, levobupivacaine had the efficacy and safety profile equivalent to bupivacaine in epidural anesthesia for Caesarean section.

Case ReportsRopivacaine-induced convulsion immediately after epidural administration--a case report.
Ropivacaine is a new long-acting amide-type local anesthetic with less toxic effects compared with bupivacaine. Here, we report a case who sustained convulsion immediately after administration of epidural ropivacaine. A 75-year-old woman was scheduled for total knee replacement. ⋯ During the episode of convulsion sinus tachycardia at a rate of 120 beats/min without the interposal of other form of cardiac arrhythmia was noted, and respiration remained intact. This suggests that ropivacaine offers a good cardiovascular stability. This example serves as another evidence to remind us that even with a negative aspiration following epidural catheter placement and an uneventful test dose injection, inadvertent intravascular injection may still happen, particularly in the elderly.

Evaluation of airway leakage using reinforced laryngeal mask during dental anesthesia with spontaneous breathing.
The purpose of this study was to evaluate whether manipulation or position change of the head during dental procedures for handicapped patients (mentally retarded) using a reinforced laryngeal mask airway for ventilation would lead to air leak. ⋯ The use of a reinforced laryngeal mask airway eliminates the complications due to endotracheal intubation and enhances the progress of the dental procedure. Although leakage may happen during dental manipulation, it usually does not raise serious problem. No serious complications such as aspiration were found in our cases. So a reinforced laryngeal mask airway may be considered to be another safe choice for maintenance of a patent airway in handicapped patients during dental procedures.

Estimation of the depth of left-sided double-lumen endobronchial tube placement using preoperative chest radiographs.
Accurate placement of the double-lumen endobronchial tube (DLETs) is essential for optimal gas exchange during one-lung ventilation. The present study was designed to estimate the insertion depth of left-sided DLET using a preoperative chest radiograph. ⋯ To get the distance from the cephalic edge of the 6th cervical vertebra to the Dc-c from the chest radiograph preoperatively would be helpful for the evaluation of the proper insertion depth of the placement of DLET.
