Randomized Controlled Trial Comparative Study
[Prevention of spinal hypotension associated with cesarean section by aortocaval compression--left 15 degree table tilt vs. uterine displacement by hand].
Women undergoing elective cesarean delivery were randomly assigned to receive a spinal anesthesia in either the semi-lateral (group SL) position or the supine position with uterine displacement (group UD). After spinal injection, group SL patients were turned to a 15 degrees left lateral supine position, and group UD patients had uterine displacement by hand. ⋯ Mean ephedrine requirement was significantly less in the SL group (P < 0.05). Apgar scores did not differ, but umbilical artery pH values were significantly higher in patients of the group SL (P < 0.01).

Randomized Controlled Trial
[Effectiveness of gum elastic bougie for tracheal intubation with Airtraq optical laryngoscope].
Although Airtraq (ATQ) is well accepted as a useful device for tracheal intubation especially in cases of difficult airway management, we sometimes encounter difficulty in insertion of a tracheal tube along the blade of ATQ across the vocal cord in spite of ATQ assistance. Gum Elastic Bougie (GEB) is well known as a practical device for intubation assistance with Macintosh laryngoscope. We studied the efficacy of GEB for intubation with ATQ. ⋯ For the people with less experience of intubation, GEB is useful assistance for intubation with ATQ. It was concluded that the combined use of ATQ and GEB is a simple and effective process for ordinary doctors or paramedics.

Randomized Controlled Trial
[Effect of amino acid and glucose infusion on perioperative body temperature and postoperative infection in patients undergoing total knee arthroplasty].
We investigated whether the perioperative amino acid infusion with glucose is effective for preventing perioperative hypothermia and postoperative infection in patients undregoing total knee arthroplasty (TKA). ⋯ These results suggest that in patients undergoing TKA receiveing amino acid infusion perioperatively, thermogenic effect and prevention of postoperative infection are similar whether exogenous glucose is infused or not.

Randomized Controlled Trial
[Effect of continuous intravenous infusion of flurbiprofen axetil and tramadol hydrochloride for postoperative pain management of laparoscopic colectomy].
In this study, we evaluated the efficacy of continuous intravenous infusion of flurbiprofen axetil (FA) combined with tramadol hydrochloride (TH) for postoperative pain control after laparoscopic colectomy. ⋯ Continuous intravenous injection of FA plus TH is more effective than FA alone for postoperative pain management after laparoscopic colectomy.

Randomized Controlled Trial Comparative Study
[Influence of tidal volume on functional residual capacity during general anesthesia].
Ventilation with lower tidal volume improves outcome in acute respiratory distress syndrome (ARDS). However, it is questionable if ventilation strategy using lower tidal volumes created for patients with ARDS can be transferred to healthy patients undergoing general anesthesia. We assessed the effects of ventilation with lower tidal volumes and conventional tidal volumes on functional residual capacity (FRC) and Pa(O2)/FI(O2) (P/F) ratio in patients undergoing general anesthesia for upper abdominal surgery. ⋯ Lower tidal volumes are better than conventional tidal volumes in view of airway pressure and lung protective strategy during general anesthesia.
