Randomized Controlled Trial Comparative Study
Comparison of the performance of four laryngoscopes in a high-fidelity simulator using normal and difficult airway.
Novel laryngoscopes may demonstrate advantages over the traditional Macintosh laryngoscope for difficult airways. Our study compared Glidescope laryngoscope, Bonfils fibrescope, and CTrach intubating laryngeal mask airway with the Macintosh laryngoscope in a simulated normal and difficult airway, considering the additional effect of previous intubation experience. ⋯ In this study, the Macintosh laryngoscope outperformed the other devices. However, the Glidescope was considered easy to use regardless of previous experience and was the preferred device for the simulated difficult airway.

Randomized Controlled Trial Comparative Study
Comparison of intrathecal fentanyl and sufentanil in low-dose dilute bupivacaine spinal anaesthesia for transurethral prostatectomy.
The administration of low-dose bupivacaine can limit the distribution of spinal block to reduce adverse haemodynamic effects. Intrathecal opioids can enhance analgesia in combination with subtherapeutic doses of local anaesthetics. We aimed at comparing the efficacy of intrathecal fentanyl and sufentanil with low-dose diluted bupivacaine for transurethral prostatectomy (TURP) in elderly patients. ⋯ Low-dose diluted bupivacaine with fentanyl 25 microg or sufentanil 5 microg can provide adequate anaesthesia without haemodynamic instability for TURP in elderly patients. However, sufentanil was superior to fentanyl in the quality of the spinal block produced.

Randomized Controlled Trial
Ultrasound-guided transversus abdominis plane block for analgesia after Caesarean delivery.
The landmark-guided transversus abdominis plane (TAP) block is an effective method of providing postoperative analgesia in patients undergoing lower abdominal surgery. We evaluated the analgesic efficacy of the ultrasound (US)-guided TAP block in patients undergoing Caesarean delivery. ⋯ The US-guided TAP block reduces morphine requirements after Caesarean delivery when used as a component of a multimodal analgesic regimen.

Randomized Controlled Trial Comparative Study
Relative potencies of bupivacaine, levobupivacaine, and ropivacaine for neonatal spinal anaesthesia.
Comparing the relative potency of new local anaesthetics such as levobupivacaine and ropivacaine with bupivacaine by the minimum local analgesic concentration model has not been described for neonatal spinal anaesthesia. This information is important to compare agents and to determine the most effective spinal dose. ⋯ Appropriate doses for infant spinal anaesthesia are 1 mg kg(-1) of isobaric 0.5% bupivacaine and ropivacaine and 1.2 mg kg(-1) of isobaric 0.5% levobupivacaine.

Randomized Controlled Trial Comparative Study
Comparison of sub-Tenon's block with i.v. fentanyl for paediatric vitreoretinal surgery.
Vitreoretinal (VR) surgery is associated with moderate to severe pain and significant postoperative nausea and vomiting (PONV). The study aimed to assess the effectiveness of sub-Tenon's block for providing perioperative analgesia in children undergoing VR surgery. ⋯ Sub-Tenon's block provides more effective analgesia than i.v. fentanyl for paediatric VR surgery.
