Combined administration of local anesthetics and an opioid is frequently used in order to minimize the dose of each drug and to reduce adverse effects. Although fentanyl is commonly administered with local anesthetic, side effects of fentanyl increase in a dose-dependent manner. In this study, we determined the optimal dose of epidural fentanyl after gynecological surgery. ⋯ Ropivacaine alone could not provide sufficient analgesia. Although the addition of 5 microg x ml(-1) fentanyl to 0.2% ropivacaine at a rate of 5 ml x hr(-1) improved postoperative pain, side effects caused by fentanyl increased. Supplementing 2 microg x ml(-1) fentanyl provided sufficient analgesia with the least incidence of side effects.

Neonates with 18-trisomy syndrome have various anomalies including cardiac and facial anomalies. Active treatments for them have not been recommended due to a low survival over one year which is less than 10%. However, the survival over one year in our institute between 1985 and 2003 is higher at 22%, and we had a patient with survival of over 5 years. ⋯ Tracheal intubation was difficult due to small airway and facial anomalies; cleft clip, cleft palate, and macrognathia. Conventional ventilation was ineffective for elimination of carbon dioxide and oxygenation due to pulmonary hypoplasia and intra- and extra-cardiac shunts. A high frequency ventilation improved elimination of carbon dioxide and oxygenation.

Aortic occlusion balloon catheter (AOBC), which occludes the descending aorta without thoracotomy, is expected to prevent further blood loss and raise blood pressure (BP). We investigated the effects of AOBC retrospectively. ⋯ In our experience, AOBC was effective for raising BP in patients in hemorrhagic shock.

We report a case of anesthesia for cesarean section in a schizophrenic patient. Her psychiatric symptoms were well controlled with low doses of risperidone until 35 weeks' gestation, when she suddenly developed psychotic manifestations. Risperidone 6 mg x day(-1) and haloperidol 12 mg x day(-1) PO were given for 3 weeks before delivery. ⋯ The parturient showed good psychiatric condition during and after the surgery. The neonate did not show any symptoms which antipsychotics could have caused. Maternal and umbilical blood concentrations of risperidone and haloperidol are reported.

Randomized Controlled Trial Comparative Study Clinical Trial
[Which is more useful for central venous catheterization? A comparison between a 22 gauge metal needle (Argyle) and a 24 gauge plastic cannula with a metal needle (Insyte)].
Central venous catheterization is commonly performed by puncturing the internal jugular vein. However, placement of central venous catheters is not without risk. We compared the Argyle and the Insyte in terms of usefulness and incidence of complications during central venous catheterization. ⋯ Using the Argyle makes it a little more difficult to place the needle in the appropriate venous lumen. We conclude that central venous catheterization with the Insyte was quicker and safer than with the Argyle.
