Retrospective evaluation of intravenous fentanyl patient-controlled analgesia during labor.
Because the safety of intravenous fentanyl patient-controlled analgesia (iv-PCA) administered during labor remains unclear, we retrospectively examined the labor records from January 2005 to December 2007 in our institution, with a focus on both maternal and neonatal outcomes, as compared to no analgesia. ⋯ As compared to no analgesia, fentanyl iv-PCA appears to be safe and clinically acceptable as analgesia during labor, particularly in nulliparous women.

The effect of cuff pressure on postoperative sore throat after Cobra perilaryngeal airway.
The cuff volume of the Cobra perilaryngeal airway (CobraPLA) is larger than that of other alternative airway devices and makes it difficult to predict the effect of cuff pressure on the perilaryngeal mucosa. We tested the hypothesis that adjustment of the cuff pressure of the CobraPLA could reduce the incidence of postoperative sore throat (POST). ⋯ Adjustment of cuff pressure reduces the incidence of moderate POST after use of the CobraPLA.

Addition of a video camera system improves the ease of Airtraq(®) tracheal intubation during chest compression.
Recent resuscitation guidelines for cardiopulmonary resuscitation emphasize that rescuers should perform tracheal intubation with minimal interruption of chest compressions. We evaluated the use of video guidance to facilitate tracheal intubation with the Airtraq (ATQ) laryngoscope during chest compression. Eighteen novice physicians in our anesthesia department performed tracheal intubation on a manikin using the ATQ with a video camera system (ATQ-V) or with no video guidance (ATQ-N) during chest compression. ⋯ In contrast, all participants successfully secured the airway with the ATQ-V, with or without chest compression. Concurrent chest compression increased the time required for intubation with the ATQ-N (without chest compression 14.8 ± 4.5 s; with chest compression, 28.2 ± 10.6 s; P < 0.05), but not with the ATQ-V (without chest compression, 15.9 ± 5.8 s; with chest compression, 17.3 ± 5.3 s; P > 0.05). The ATQ video camera system improves the ease of tracheal intubation during chest compressions.

The antinociceptive effect of intrathecal tramadol in rats: the role of alpha 2-adrenoceptors in the spinal cord.
The alpha 2 (α(2))-adrenoceptor is highly important in the antinociception of tramadol administered systemically and intrathecally. However, it is unclear whether tramadol at the spinal level exerts an antinociceptive effect by directly binding with α(2)-adrenoceptors in the spinal cord. This study was conducted to investigate the relationship between α(2)-adrenoceptors and the antinociception of tramadol at the spinal level. ⋯ The results suggested that, with very weak binding affinity for α(2)-adrenoceptors, the antinociception of intrathecal tramadol is partially related to α(2)-adrenoceptors, and its intrathecal antinociception may mainly involve its indirect activation of α(2)-adrenoceptors in the spinal cord.
