Randomized Controlled Trial Comparative Study
Comparison of desflurane with sevoflurane for the incidence of oculocardiac reflex in children undergoing strabismus surgery.
The oculocardiac reflex (OCR) is frequently observed during strabismus surgery. This study was designed to evaluate and compare the effect of sevoflurane and desflurane on the incidence of OCR. ⋯ Both agents can be used safely during strabismus surgery in paediatric patients.

Review Meta Analysis
Superficial or deep cervical plexus block for carotid endarterectomy: a systematic review of complications.
Carotid endarterectomy is commonly conducted under regional (deep, superficial, intermediate, or combined) cervical plexus block, but it is not known if complication rates differ. We conducted a systematic review of published papers to assess the complication rate associated with superficial (or intermediate) and deep (or combined deep plus superficial/intermediate). The null hypothesis was that complication rates were equal. ⋯ The conversion rate to general anaesthesia was also higher with deep/combined block (odds ratio 5.15, P < 0.0001), but there was an equivalent incidence of other systemic serious complications (odds ratio 1.13, P = 0.273; NS). We conclude that superficial/intermediate block is safer than any method that employs a deep injection. The higher rate of conversion to general anaesthesia with the deep/combined block may have been influenced by the higher incidence of direct complications, but may also suggest that the superficial/combined block provides better analgesia during surgery.

Randomized Controlled Trial Comparative Study
Comparison of two induction regimens using or not using muscle relaxant: impact on postoperative upper airway discomfort.
Intubation without muscle relaxant is associated with greater incidence of sore throat, hoarseness, hypotension, bradycardia and intubation difficulty.

Randomized Controlled Trial
The effect of ephedrine on intubating conditions and haemodynamics during rapid tracheal intubation using propofol and rocuronium.
We compared the effect of pre-treatment with ephedrine 75, 100, 150 microg kg(-1) and saline on intubating conditions and haemodynamics during rapid tracheal intubation using propofol and rocuronium. ⋯ Ephedrine either 75 or 100 microg kg(-1) given before rapid tracheal intubation using propofol and rocuronium bromide improves the intubation conditions. It is not effective in preventing the hypotension which follows ensuing induction of anaesthesia.

Randomized Controlled Trial
Epidural naloxone reduces postoperative nausea and vomiting in patients receiving epidural sufentanil for postoperative analgesia.
Epidural opioids have excellent analgesic properties, but their side-effects limit their use in patient-controlled epidural analgesia. This study was designed to evaluate the effect of epidural naloxone on the side-effects of sufentanil, focusing on postoperative nausea and vomiting (PONV) in patients undergoing total knee replacement (TKR). ⋯ Epidural naloxone was effective in reducing PONV induced by epidural sufentanil and additionally enhanced the analgesic effect. Therefore, concomitant infusion of a small dose of epidural naloxone should be considered to reduce PONV, especially in patients at greater risk for PONV.
