Randomized Controlled Trial
Bispectral index for monitoring anesthetic depth in patients with severe burns receiving target-controlled infusion of remifentanil and propofol.
This study evaluated the feasibility and effectiveness of using the bispectral index (BIS) to monitor anesthetic depth in patients with severe burns receiving intravenous target-controlled infusion (TCI) of remifentanil and propofol. We randomly assigned 80 patients undergoing elective escharectomy (<1 week) to BIS (A) and control (B) groups. All patients received remifentanil and propofol as intravenous TCI anesthesia. ⋯ The time from drug withdrawal to eye opening upon the patient hearing his/her name called and reaching an Aldrete score of 9 points in group A was considerably shorter than that in group B (7.90 ± 0.58 vs 8.35 ± 0.66 min and 9.15 ± 0.69 vs 11.13 ± 0.96 min, respectively; P < 0.01). In both groups, mean arterial pressure and heart rate values at each time point after loss of consciousness were significantly lower than the baseline values (P < 0.05), with the exception of 2 min after intubation. The use of BIS to monitor anesthetic depth in patients with severe burns receiving TCI of remifentanil and propofol during the perioperative period reduces propofol consumption and shortens the consciousness recovery time in patients.

Effects of goal-directed fluid therapy with different lactated Ringer's: hydroxyethyl starch ratios in hemorrhagic shock dogs.
The effects of goal-directed fluid therapy, with lactated Ringer's (LR) and 6% hydroxyethyl starch (HES) solution, on hemorrhagic shock dogs are unknown. We aimed to determine the optimal LR: HES ratio for the resuscitation of hemorrhagic shock dogs. Hemorrhagic shock was induced in 40 ventilated dogs by drawing an estimated 60% blood volume. ⋯ In contrast to the 3:1 group at R24 and baseline, plasma chloride and sodium in the 1:3 and 1:2 groups increased; however, pH, BE, and Clearcrea decreased (P < 0.05). No significant differences were found in the 1:1 and 2:1 groups at R24 compared with baseline (P > 0.05). Resuscitation with LR and HES at 2:1 and 1:1 ratios are superior in maintaining the acid-base, electrolyte, and lung water balances as well as renal function in hemorrhagic shock dogs than at ratios of 3:l, 1:2, and1:3.

Randomized Controlled Trial
Feasibility of comfortable and secure intubation achieved with the Disposcope endoscope or Macintosh laryngoscope for patients in whom glottis viewing is difficult.
We aimed to study the feasibility of a comfortable and secure intubation achieved with the Disposcope endoscope or Macintosh laryngoscope when glottis viewing is difficult. Forty adults scheduled for elective surgery under general anesthesia, in whom glottis viewing was difficult with the Macintosh laryngoscope (classified as Cormack-Lehane Grade III or IV), were randomized into 2 groups (N = 20 each): Disposcope endoscope (Group D) and Macintosh laryngoscope (Group M). We recorded the successful glottis viewing rate; intubation time; successful intubation rate; incidence of systolic blood pressure (SBP) ≥140 mmHg and heart rate (HR) ≥90 bpm from the beginning of intubation to 5 min after intubation; and postoperative sore throat and hoarseness. ⋯ No significant differences were found in other indices (P > 0.05). Better stability of hemodynamics, less intubation time, higher successful first intubation rate, and fewer incidences of postoperative sore throat were achieved in Group D than in Group M. Thus, comfortable and secure intubation can be achieved using the Disposcope endoscope in patients in whom glottis viewing is difficult.

Randomized Controlled Trial
Safety of recombinant human granulocyte-macrophage colony-stimulating factor in healing pediatric severe burns.
We explored the safety of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) for healing burns in children. Subjects were randomly assigned to two groups: the experimental group received external rhGM-CSF gel, and the control group received rhGM-CSF gel matrix components, applied to the burn surface. Neither group was given any other drugs that promote wound healing. ⋯ There were no obvious adverse reactions. There was no significant difference between the blood routine, urine routine, and liver and kidney function in the two groups before the treatment and after 3 days (P > 0.05). Compared with saline treatment of severe burns, rhGM-CSF can effectively shorten the healing time without significant adverse reactions, and is an effective and safe treatment for burns in children.

Randomized Controlled Trial Clinical Trial
A randomized trial to compare pain control using oral analgesia with epidural analgesia after cesarean section following combined spinal-epidural anesthesia.
This study aimed to evaluate whether combined oral oxycodone hydrochloride-controlled release tablets plus paracetamol and tramadol hydrochloride tablets are more effective than epidural analgesia for postoperative pain control and side effects after cesarean section. We randomly enrolled 60 patients scheduled for cesarean section into either: patient-controlled epidural analgesia with 0.1% ropivacaine+0.1 μg/mL sufentanil (for postoperative 48 h)+injected pethidine on demand (E group); or controlled-release oxycodone (2x15 mg for the first postoperative 24 h; 2x10 mg for the second postoperative 24 h)+paracetamol and tramadol hydrochloride tablets (8x1 tablet for the postoperative 48 h) orally+injected pethidine on demand (O group). The E group experienced more evoked pain and uterine cramping pain at all times postoperatively. ⋯ Maternal satisfaction with the analgesia regimen was lower in the E group (P<0.01). The median duration of hospital stay was about 5 days for both groups. Postoperative pain control after cesarean section with oral oxycodone hydrochloride-controlled release tablets plus paracetamol and tramadol hydrochloride tablets is preferable to epidural analgesia, even when side effects and maternal satisfaction are taken into account.
