Randomized Controlled Trial
Use of laryngeal mask airway and its removal in a deeply anaesthetized state reduces emergence agitation after sevoflurane anaesthesia in children.
This study investigated the effect of laryngeal mask airway (LMA) and removal while in a deeply anaesthetized state (deep removal) compared with endotracheal tube and extubation when awake or deeply anaesthetized on the incidence of emergence agitation in children after sevoflurane anaesthesia for subumbilical surgery. Patients (2 - 7 years) were randomly assigned to one of three groups: ET-A group (n = 56, endotracheal tube and extubation whilst awake); ET-D group (n = 56, endotracheal tube and deep extu bation); LMA-D group (n = 56, experienced LMA and deep removal). ⋯ There were no significant differences in the incidence of postoperative emergence agitation or length of stay in the PACU between the ET-A and ET-D groups, or between the ET-D and LMA-D groups. In conclusion, using an LMA and deep removal decreased postoperative emergence agitation compared with using an endotracheal tube and awake extubation after paediatric sevoflurane anaesthesia.

Randomized Controlled Trial
The analgesic effect of dexketoprofen when added to lidocaine for intravenous regional anaesthesia: a prospective, randomized, placebo-controlled study.
This prospective, randomized, placebo-controlled study evaluated the effects of dexketoprofen as an adjunct to lidocaine in intravenous regional anaesthesia (IVRA) or as a supplemental intravenous (i.v.) analgesic. Patients scheduled for elective hand or forearm soft-tissue surgery were randomly divided into three groups. All 45 patients received 0.5% lidocaine as IVRA. ⋯ The times of sensory and motor block onset, recovery time and postoperative analgesic consumption were recorded. Compared with controls, the addition of dexketoprofen to the IVRA solution resulted in more rapid onset of sensory and motor block, longer recovery time, decreased intra- and postoperative pain scores and decreased paracetamol use. It is concluded that coadministration of dexketoprofen with lidocaine in IVRA improves anaesthetic block and decreases postoperative analgesic requirements.

The prevalence of painful diabetic peripheral neuropathy (DPN) was evaluated in type 1 or type 2 diabetes mellitus patients (n = 4097) attending outpatient clinics across the Middle East. Overall, 53.7% of 3989 patients with DN4 data met the criteria for painful DPN (Douleur Neuropathique-4 [DN4] scores ≥ 4). ⋯ The odds of painful DPN were highest among patients with peripheral vascular disease (OR 4.98), diabetic retinopathy (OR 3.90) and diabetic nephropathy (OR 3.23). Because of the high prevalence and associated suffering, disability and economic burden of painful DPN, it is important that diabetic patients are periodically screened, using a simple instrument such as the DN4, and receive appropriate treatment if symptoms develop.

Total intravenous anaesthesia (TIVA) can reduce the risk of postoperative nausea and vomiting (PONV) almost as much as a single antiemetic. This study compared TIVA (using propofol and remifentanil) with prophylactic palonosetron (a 5-hydroxytryptamine type 3 receptor antagonist) combined with inhalation anaesthesia using sevoflurane in 50% nitrous oxide, for the prevention of PONV. ⋯ The incidence of PONV was around 50% in both groups and the severity of nausea was similar in both groups. Prophylactic palonosetron with inhalational anaesthesia using sevoflurane in 50% nitrous oxide reduced the incidence of PONV after gynaecological laparoscopic surgery almost as much as TIVA using propofol and remifentanil.

Randomized Controlled Trial
Reduction of microemulsion propofol-induced injection pain via target-controlled remifentanil infusion.
The intravenous injection of microemulsion propofol to induce anaesthesia causes more intense and frequent pain than lipid emulsion propofol. This study investigated whether different target effect-site concentrations of remifentanil could prevent pain due to microemulsion propofol injection. ⋯ Although no difference in pain reduction between the two remifentanil-treated groups was observed, those receiving a target effect-site concentration of 6 ng/ml exhibited an increased rate of complications, compared with those receiving 4 ng/ml. In conclusion, prior administration of remifentanil at a target effect-site concentration of 4 ng/ml is a useful strategy to decrease the injection pain of microemulsion propofol.
