Randomized Controlled Trial Clinical Trial
Patient anxiety scores after low-dose ketamine or fentanyl for epidural catheter placement.
To compare the effect of low-dose ketamine with that of low-dose fentanyl on patient anxiety during the identification of the epidural space and catheterization. ⋯ Ketamine, 5 mg iv, is as effective as 50 microg fentanyl, iv, in alleviating patient anxiety and in providing adequate sedation during the procedures necessary for epidural catheter placement, without inducing severe complications.

Randomized Controlled Trial Comparative Study Clinical Trial
The intubating LMA: a comparison of insertion techniques with conventional tracheal tubes.
To compare the performance of the intubating laryngeal mask airway (ILMA) in assisting blind tracheal intubation with conventional tracheal tubes of different curvatures and the frequency of possible associated complications. ⋯ Blind trachea intubation via an ILMA with the conventional curved tracheal tube is feasible and highly successful. Reverse curve direction is preferable at the first attempt of intubation for its higher success rate and lower incidence of complications.

Randomized Controlled Trial Comparative Study Clinical Trial
Optimal dose of intrathecal clonidine added to sufentanil plus bupivacaine for labour analgesia.
The combination of intrathecal (IT) 5 microg sufentanil plus 1.25 mg bupivacaine is useful for inducing labour analgesia, albeit of short duration and slow onset. As a supplementation to this regimen, the effect of IT clonidine on the duration of analgesic action was investigated. ⋯ The optimal dose of intrathecal clonidine to enhance labour analgesia with the current sufentanil-bupivacaine regimen is 15 microg. In view of the side effect profile, doses greater than 30 microg clonidine are unlikely to be useful.

Randomized Controlled Trial Clinical Trial
Intubating laryngeal mask for fibreoptic intubation--particularly useful during neck stabilization.
To assess the ease of fibrescope-assisted tracheal intubation while the patient's head and neck were placed in the neutral or the manual in-line position, and to determine if the intubating laryngeal mask facilitated fibreoptic intubation in these positions. ⋯ Fibreoptic tracheal intubation was more difficult in the manual in-line position than in the neutral position. The intubating laryngeal mask facilitated fibreoptic intubation in both positions.

To compare surface and intramuscular laryngeal electromyography (EMG) with adductor pollicis muscle EMG after 0.1 mgxkg(-1) cisatracurium. ⋯ Surface laryngeal EMG is comparable to intramuscular laryngeal EMG to determine degree and onset of the neuromuscular blockade. Increasing muscle relaxation does not cause the surface electrode to lose contact with the vocal cords and therefore underestimate onset time and peak effect.
