Randomized Controlled Trial Comparative Study
Comparison of desflurane and sevoflurane anaesthesia in relation to the risk of vagally mediated reflex bradycardia during gastrectomy.
This study compared the risk of clinically significant reflex bradycardia during anaesthesia with sevoflurane or desflurane in patients undergoing gastrectomy. ⋯ Clinically significant reflex bradycardia occurred with a relatively high frequency during gastrectomy. Although desflurane is associated with sympathetic activation, it did not provide a protective effect against vagally mediated reflex bradycardia during gastrectomy compared with sevoflurane.

Randomized Controlled Trial
Efficacy and safety of an intra-operative intra-articular magnesium/ropivacaine injection for pain control following total knee arthroplasty.
Eighty patients with osteoarthritis who underwent unilateral total knee arthroplasty were randomly assigned to two groups: the trial group received an intra-operative intra-articular injection of magnesium sulphate and ropivacaine, and the control group received an injection of normal saline. All patients received patient-controlled analgesia with morphine for 48 h post-operatively. ⋯ The time to be able to perform a straight leg raise and to reach a 90° knee flexion was significantly shorter in the trial group compared with the controls. This study demonstrated that an intra-operative intra-articular magnesium sulphate and ropivacaine injection reduced the use of post-operative morphine.

Randomized Controlled Trial Comparative Study
Response to nonsteroidal anti-inflammatory drugs in African Americans with osteoarthritis of the knee.
This 6-week, randomized, double-blind, parallel-group study compared the analgesic efficacy, tolerability and safety of celecoxib, naproxen and placebo in African Americans with osteoarthritis (OA) of the knee. ⋯ Celecoxib was as effective as naproxen in relieving OA pain in African Americans and was well tolerated. Few significant differences were observed between active treatments and placebo, possibly because of a strong placebo effect.

Randomized Controlled Trial Comparative Study
Dexmedetomidine versus midazolam for conscious sedation in postoperative patients undergoing flexible bronchoscopy: a randomized study.
This prospective randomized study evaluated the efficacy and patient tolerance of dexmedetomidine compared with midazolam for sedation in postoperative patients undergoing flexible bronchoscopy. ⋯ Compared with midazolam, dexmedetomidine provided better oxygen saturation and was equally well tolerated for conscious sedation in postoperative patients undergoing bronchoscopy.

Randomized Controlled Trial Comparative Study
The effects of epidural anaesthesia and analgesia on natural killer cell cytotoxicity and cytokine response in patients with epithelial ovarian cancer undergoing radical resection.
Epidural anaesthesia appears to promote antitumourigenic activity in patients with malignant disease who are undergoing surgery. This study investigated immune function in women with epithelial ovarian cancer undergoing radical resection with either general anaesthesia alone or in combination with epidural anaesthesia. ⋯ Combined general/epidural anaesthesia appeared to promote antitumourigenic NKCC and cytokine responses.
