Randomized Controlled Trial Comparative Study Clinical Trial
Assessment of neuromuscular and haemodynamic effects of cisatracurium and vecuronium under sevoflurane-remifentanil anaesthesia in elderly patients.
Neuromuscular block times, quality of muscle relaxation for tracheal tube insertion, and the haemodynamic effects after cisatracurium and vecuronium under sevoflurane-remifentanil anaesthesia were compared in elderly patients. ⋯ In elderly patients, vecuronium has a faster onset time while cisatracurium has a shorter recovery index under sevoflurane-remifentanil anaesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Induced hypotension for tympanoplasty: a comparison of desflurane, isoflurane and sevoflurane.
This prospective, randomized, double-blinded study was designed to compare the effects of desflurane, isoflurane and sevoflurane when combined with remifentanil for induced hypotension on surgical conditions and operative field during tympanoplasty. ⋯ Desflurane, sevoflurane or isoflurane combined with remifentanil provided adequate induced hypotension and similar operating conditions and any of them could be safely and equally used in anaesthesia for tympanoplasty.

Cervical spine movement may be limited for morphological reasons or through injury. The major goal of the present study was to evaluate the three-dimensional cervical spine movement during intubation with a Macintosh or Bullard laryngoscope, a Bonfils fibrescope or an intubating laryngeal mask using an ultrasound-based motion system. ⋯ Our findings suggest that the Bullard laryngoscope may be a useful adjunct to intubate patients with cervical spine injuries. In elective situations when time to intubation is not critical Bonfils as well as intubating laryngeal mask airway should also be considered as serious alternatives to direct laryngoscopy.

Although local anaesthesia is mentioned in historical manuscripts, it is only a hundred years since Bier first reported the intrathecal use of local anaesthetic agents. This has been followed by a rapid progression in the art and science of spinal anaesthesia. Isomerically pure agents with favorable clinical profiles, such as ropivacaine and levobupivacaine are now available. ⋯ In addition to traditional spinal anaesthesia, local anaesthetics are now being evaluated in continuous spinal anaesthesia and combined epidural-spinal anaesthesia. This article reviews clinical experience with levobupivacaine and ropivacaine. Compared with levobupivacaine, ropivacaine generally produces a less intense motor block of shorter duration, which has advantages for earlier mobilization and discharge from hospital and may be particularly useful in obstetrics and ambulatory surgery.
