Randomized Controlled Trial Clinical Trial
Performance of bispectral index and auditory evoked potential monitors in detecting loss of consciousness during anaesthetic induction with propofol with and without fentanyl.
To investigate and compare the performance of bispectral index (BIS) and auditory evoked response index (AAI) in detecting the transition from consciousness to unconsciousness during anaesthesia induction by propofol, alone and in combination with fentanyl. ⋯ These results show that a fentanyl bolus is effective in augmenting the hypnotic effect of propofol during anaesthesia induction. AAI appears to be able to measure the transition from consciousness to unconsciousness at similar values, regardless of whether or not fentanyl pretreatment is used whereas the BIS values were not independent of fentanyl pretreatment. This suggests that AAI may be a better indicator of conscious status during propofol/fentanyl anaesthesia, where it appears to be independent of the anaesthesia regimen.

Sufentanil supplementation of sevoflurane during induction of anaesthesia: a randomized study.
The use of opioids with sevoflurane for induction of anaesthesia is associated with fewer reactions to laryngoscopy but increases the risk of apnoea. Thus it is important to search for the optimal opioid dose. The aim of this study was to compare two sufentanil doses during induction with sevoflurane in young adults. ⋯ In current clinical practice during sevoflurane induction, sufentanil 0.30 microg kg(-1) provided a better quality of induction than sufentanil 0.15 microg kg(-1), without significant cardiovascular depression, although the risk of apnoea is increased.

Upper cervical vertebrae movement during intubating laryngeal mask, fibreoptic and direct laryngoscopy: a video-fluoroscopic study.
Minimizing cervical vertebrae motion during endotracheal intubation is important in patients with cervical instability. The aim of this study was to compare upper cervical spine extension during endotracheal intubation using three different techniques. ⋯ We conclude that fibreoptic laryngoscopy is the more suitable intubation technique when cervical spine movement is not desired.

Randomized Controlled Trial Clinical Trial
Ropivacaine 0.1% with fentanyl 2 microg mL(-1) by epidural infusion for labour analgesia.
To evaluate the efficacy of 0.1% ropivacaine with fentanyl 2 microg mL(-1) via epidural for analgesia in labour. ⋯ An epidural infusion of 0.1% ropivacaine with fentanyl 2 microg mL(-1) at 10 mL h(-1) provided adequate analgesia in the first stage of labour. The level of analgesia was similar to that obtained using 0.2% ropivacaine with fentanyl 2 microg mL(-1) and with no differences with regard to motor or sensory block.

In 1991 general anaesthesia was used extensively for emergency Caesarean section at Haukeland University Hospital even in patients with an ongoing epidural infusion. With increased knowledge of the potential safety benefits of regional anaesthesia and increased experience with the technique, we decided to use indwelling epidural catheters for emergency Caesarean section. ⋯ The increase in the use of indwelling epidural catheters for emergency Caesarean section has resulted in a significant increase in the use of regional anaesthesia. A modest increase in time elapsed before start of surgery was observed although there were no significant differences in the number of neonates with low Apgar scores. No major complications were observed, but there was an increased frequency of minor complications in 1997.
