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.

Controlled Clinical Trial
Contamination of salvaged maternal blood by amniotic fluid and fetal red cells during elective Caesarean section.
Cell salvage in obstetrics is still a controversial subject and has yet to be fully embraced. The aim of this exploratory study was to measure amniotic fluid (AF), heparin, and fetal red cell contamination of washed filtered salvaged maternal blood and to investigate differences based on the number of suction devices used. ⋯ This study adds to the growing body of evidence that there is little or no possibility for AF contamination to enter the re-infusion system when used in conjunction with a leucodepletion filter.

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.

Randomized Controlled Trial
Effect of landiolol on bispectral index and spectral entropy responses to tracheal intubation during propofol anaesthesia.
beta1-Adrenoceptor antagonists suppress the haemodynamic and arousal responses to tracheal intubation. The Entropy Module shows two spectral entropy-based indices, response entropy (RE) and state entropy (SE). The difference between RE and SE (RE-SE) may reflect nociception during general anaesthesia. In the present study, we investigated the effect of landiolol on entropy indices in response to tracheal intubation. ⋯ RE increased in response to tracheal intubation, whereas BIS and SE did not. Landiolol and remifentanil suppressed the increase in RE after tracheal intubation with significant inhibition of RE-SE difference.
