Randomized Controlled Trial Comparative Study
The postoperative analgesic efficacy of intraperitoneal tramadol compared to normal saline or intravenous tramadol in laparoscopic cholecystectomy.
The aim of this study was to compare the postoperative analgesic efficacy of intraperitoneal tramadol with intravenous tramadol or normal saline in patients undergoing laparoscopic cholecystectomy. ⋯ Intravenous tramadol provides superior postoperative analgesia in the early postoperative period after laparoscopic cholecystectomy compared with an equivalent dose of tramadol administered intraperitoneally and with normal saline in patients undergoing laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative Study
Comparison between dexmedetomidine and remifentanil for controlled hypotension during tympanoplasty.
Controlled hypotension is frequently used for obtaining better exposure during tympanoplasty. The aim of this study was to compare dexmedetomidine, a selective, short-acting, central alpha2-adrenergic agonist with remifentanil, an ultra-short-acting opioid with properties similar to other mu-specific agonists, regarding their effects in achieving controlled hypotension and improving surgical field exposure and surgeon's satisfaction during tympanoplasty. ⋯ Infusion of dexmedetomidine, at the doses used in this study, was less effective than remifentanil in achieving controlled hypotension, good surgical field exposure condition and surgeons' satisfaction during tympanoplasty.

Multicenter Study
Stable plasma concentrations of unbound ropivacaine during postoperative epidural infusion for 24-72 hours in children.
The aim of this open, non-controlled, multi-centre study was to evaluate the pharmacokinetics and safety of a 24-72 h continuous epidural ropivacaine infusion in children aged 1-9 yr. ⋯ Following a 24-72 h epidural infusion of ropivacaine 0.4 mg kg(-1) h(-1) in 1-9-yr-old children, the plasma concentrations of unbound ropivacaine were stable over time with no age-dependency.

Comparative Study
Age-adapted morphine titration produces equivalent analgesia and adverse effects in younger and older patients.
To determine the efficacy and safety of intravenous postoperative morphine titration in the elderly compared with younger patients. ⋯ Using lower bolus doses, pain relief in the immediate postoperative period with morphine was as efficacious and safe in elderly patients as in younger patients. The decrease in renal clearance of morphine in the elderly justifies the reduction of intravenous morphine boluses for the treatment of postoperative pain.
