Review Meta Analysis
Acupuncture and related techniques for postoperative pain: a systematic review of randomized controlled trials.
Postoperative pain management remains a significant challenge for all healthcare providers. The objective of this systematic review was to quantitatively evaluate the efficacy of acupuncture and related techniques as adjunct analgesics for acute postoperative pain management. We searched the databases of Medline (1966-2007), CINAHL, The Cochrane Central Register of Controlled Trials (2006), and Scopus for randomized controlled trials (RCTs) using acupuncture for postoperative pain management. ⋯ Postoperative pain intensity (visual analogue scale, 0-100 mm) was also significantly decreased in the acupuncture group at 8 and 72 h compared with the control group. The acupuncture treatment group was associated with a lower incidence of opioid-related side-effects such as nausea (relative risk, RR: 0.67; 95% CI: 0.53, 0.86), dizziness (RR: 0.65; 95% CI: 0.52, 0.81), sedation (RR: 0.78; 95% CI: 0.61, 0.99), pruritus (RR: 0.75; 95% CI: 0.59, 0.96), and urinary retention (RR: 0.29; 95% CI: 0.12, 0.74). Perioperative acupuncture may be a useful adjunct for acute postoperative pain management.

Randomized Controlled Trial Comparative Study
Comparison of the effects of thoracic and lumbar epidural anaesthesia on induction and maintenance doses of propofol during total i.v. anaesthesia.
In this randomized, double-blind study, the effects of thoracic and lumbar epidural anaesthesia on the induction doses (IDs) and maintenance doses (MDs) of propofol during bispectral index (BIS) guided total i.v. anaesthesia were compared. ⋯ Similar segments blocked with epidural anaesthesia have resulted in similar ID. During maintenance, identical amounts of bupivacaine applied from different levels have resulted in different MD of propofol. The concentration of the epidural anaesthesia appears to play a more important role than the applied amount of the local anaesthetic.

Clinical Trial
Propofol-based sedation regimen for infants and children undergoing ambulatory magnetic resonance imaging.
Propofol is widely used for infants and children requiring sedation for magnetic resonance imaging. However, increased doses of propofol may quickly lead to an unintended deep sedation and respiratory depression. Thus, an appropriate low dosage, which nevertheless ensures sufficient sleep for successful magnetic resonance imaging (MRI) completion, would probably minimize respiratory adverse events. We investigated the safety and efficacy of a low-dose propofol-based sedation regimen in a broad age range of children. ⋯ This sedation regimen provides the shortest induction time so far described, a rare demand for additional sedation, a low incidence of respiratory events, and a rapid recovery.

The right ventricular ejection fraction pulmonary artery catheter (RVEF-PAC) has been widely used to monitor the right ventricular (RV) function during orthotopic liver transplantation (OLT). However, the evaluation of the RVEF during this procedure during propofol anaesthesia has not been described. ⋯ Although the baseline RVEF was decreased, it showed only minor alterations throughout the procedure, suggesting that the RV function is not significantly compromised during OLT under propofol anaesthesia.

Randomized Controlled Trial
Influence of the anaesthetic depth on the inhibition of the oculocardiac reflex during sevoflurane anaesthesia for paediatric strabismus surgery.
It remains controversial whether the anaesthetic depth as assessed by bispectral index (BIS) influences the oculocardiac reflex (OCR) during strabismus surgery. We investigated whether BIS-guided sevoflurane titration may help to optimize the anaesthetic depth for inhibition of the OCR during paediatric strabismus surgery. ⋯ We confirmed that OCR is relevant to the depth of anaesthesia. BIS values of 40-50 seem adequate for the inhibition of OCR. The results suggest that BIS may be a valuable tool during sevoflurane anaesthesia for strabismus surgery in children.
