Randomized Controlled Trial Clinical TrialSupplementing epidural lidocaine with midazolam: effect on sensorymotor block level.
Midazolam, the only clinically available water-soluble benzodiazepine, has been reported to have an antinociceptive effect through neuroaxial pathway. Also it can be used epidurally for postoperative analgesia and chronic pain management. In a recent study it was disclosed that when midazolam was added to intrathecal bupivacaine it improved the duration and quality of the spinal anesthesia. In this study the effects of this drug on intraoperative motor and sensory blocks were evaluated. ⋯ Midazolam can improve the durations of sensory and motor blocks of lidocaine in a single epidural administration. It seems that the 5 mg dosage works better than the lower one.

A survey for prevention and treatment of malignant hyperthermia in Taiwan.
Malignant hyperthermia (MH) is a hypermetabolic disorder with high mortality. Intravenous administration of dantrolene is the specific treatment. However, the only means to lower mortality rate are early detection and suitable treatment. Therefore, properly monitoring and handy availability of dantrolene are essential to lower the mortality of MH. This study was designed to evaluate the capabilities in prevention and treatment of MH of the hospitals in Taiwan. ⋯ This study has revealed that in some hospitals in Taiwan intraoperatively (anesthetic) monitoring is inadequate and there is no stockpile of dantrolene for immediate treatment of MH. We recommend that appropriate anesthetic monitoring equipment should be strictly applied and a stock of initial dose of dantrolene (6 vials) should be kept, which are necessary for early diagnosis and treatment of MH.

Nitrous oxide uptake in man: a new concept of uptake of inhalation anesthetics.
With proper recognition of the functional residual capacity (FRC) and the existence of the alveolar membrane in consideration of gas uptake, the uptake of nitrous oxide does not follow the previously described power function of time, 1,000 ml x t(-1/2). ⋯ In contrast to previous publications, in which the time course of FA/FI was used to express the uptake of nitrous oxide, in spite of the area under the curve of FA/FI should not be used to express uptake, instead, the area above the curve, (1-FA/FI), fits the results and should be considered as representing uptake.

Frequent use of alternative airway techniques makes difficult intubations less and easier.
This study is to evaluate how alternative airway techniques work at different scenarios of difficult airways in our department where those techniques are popularized in daily practice. ⋯ In elective general anesthesia, frequent use of the alternative airway techniques, such as LMA for a surgical procedure of short duration and lighting stylet for a possibly difficult airway, will decrease the events of difficult intubations. Lighting stylet seems more advantageous than laryngoscope in management of difficult intubation caused by poor laryngoscopic view.

Case ReportsOccurrence of the Bezold-Jarisch reflex during Cesarean section under spinal anesthesia--a case report.
We report a 35-year-old parturient with gestational diabetes mellitus (GDM) history who sustained a nearly fatal Bezold-Jarisch reflex during Cesarean section under spinal anesthesia. A high spinal block combined with acute massive hemorrhage may produce life-threatening Bezold-Jarisch reflex which should be treated prophylactically and aggressively during surgery. Additionally, the autonomic disturbance associated with GDM might exaggerate the reflex in this episode. The patient survived after successful resuscitation and was discharged without any sequela.
