Randomized Controlled Trial Comparative Study
A comparison of the efficacies of different pre-treatment drugs in resolving the injection pain of rocuronium.
Efficacies of pre-treatment with lidocaine, remifentanil and metoclopramide in the reduction of pain and withdrawal movements induced by rocuronium injection were evaluated. Forty-four adult patients, American Society of Anesthesiologists (ASA) Physical Status I-II, undergoing elective surgery were randomly assigned to four groups. Each patient received intravenously either 10 mg metoclopramide, 50 mg lidocaine, 1 microg/kg remifentanil or 3 ml of 0.9% sodium chloride (control group); followed by occlusion with a tourniquet on the forearm. ⋯ After loss of consciousness with sodium thiopental, 0.6 mg/kg rocuronium was administered for intubation and withdrawal movements were assessed. The number of patients in whom withdrawal movements were lowest was in the lidocaine-treated group. Although there was no difference among the study drugs in the prevention of rocuronium-induced pain, lidocaine and remifentanil seemed to be clinically more effective than metoclopramide.

Randomized Controlled Trial Comparative Study
The effect of pre-operative lornoxicam and ketoprofen application on the morphine consumption of post-operative patient-controlled analgesia.
We compared the efficacy of pre-operative intramuscular lornoxicam and ketoprofen for post-operative analgesia in patients undergoing abdominal hysterectomy. This randomized, double-blind, placebo-controlled, parallel-group study investigated 60 patients who received lornoxicam (group L, 8 mg), ketoprofen (group K, 100 mg) or saline (group C) 60 min before standard anaesthesia. ⋯ Morphine consumption in groups L and K was significantly lower than in group C. Pre-emptive administration of lornoxicam and ketoprofen effectively reduced post-operative pain and morphine consumption, and lornoxicam was more effective than ketoprofen in the early post-operative period.

Randomized Controlled Trial
The maternal and neonatal effects of the volatile anaesthetic agents desflurane and sevoflurane in caesarean section: a prospective, randomized clinical study.
This study compared maternal and neonatal outcomes in women undergoing elective caesarean section under general anaesthesia with desflurane or sevoflurane; the neonatal effects were also compared with those in women undergoing epidural anaesthesia. Fifty women requesting general anaesthesia were randomly assigned to receive either 3% desflurane or 1% sevoflurane. Twenty-five women requesting regional anaesthesia received epidural anaesthesia with ropivacaine. ⋯ Comparing general and epidural anaesthesia, no significant differences were detected in terms of neonatal Apgar scores or neurological adaptive capacity scores. In conclusion, 3% desflurane or 1% sevoflurane for general anaesthesia and ropivacaine for epidural anaesthesia for elective caesarean section had similar effects on neonatal outcomes. In women who received desflurane, blood pressure and heart rate elevation were significantly higher than in the sevoflurane group, though this difference did not have any clinical importance.

Randomized Controlled Trial Comparative Study
Effects of selective brain cooling in patients with severe traumatic brain injury: a preliminary study.
We prospectively investigated non-invasive selective brain cooling (SBC) in patients with severe traumatic brain injury. Sixty-six in-patients were randomized into three groups. In one group, brain temperature was maintained at 33 - 35 degrees C by cooling the head and neck (SBC); in a second group, mild systemic hypothermia (MSH; rectal temperature 33 - 35 degrees C) was produced with a cooling blanket; and a control group was not exposed to hypothermia. ⋯ The percentage of patients with a good neurological outcome 2 years after injury was 72.7%, 57.1% and 34.8% in the SBC, MSH and control groups, respectively. Complications were managed without severe sequelae. Non-invasive SBC was safe and effective.

Randomized Controlled Trial Comparative Study
Comparison of letrozole and clomiphene citrate in women with polycystic ovaries undergoing ovarian stimulation.
Letrozole was compared with clomiphene citrate (CC) as a first-line treatment for ovulation induction in women with polycystic ovaries (PCOs). A total of 106 women with primary infertility and a diagnosis of PCOs were randomized to receive either 100 mg CC (n = 55) or 2.5 mg letrozole (n = 51) daily for 5 days. ⋯ The number of mature follicles was significantly lower, but endometrial thickness and ovulation and pregnancy rates were significantly higher in the letrozole group than in the CC group. In conclusion, letrozole is associated with a higher pregnancy rate than CC in PCO patients and may have a role as a first-line treatment for anovulatory patients with PCOs.
