Preoperative evaluation of the cervical spine in children with trisomy-21: results of a questionnaire study.
Atlantoaxial subluxation (AAS) is a form of cervical spine instability predominantly found in persons with Trisomy-21. Several case reports describe the occurrence of acute AAS in the perioperative period. Some authors have recommended cervical spine radiographs prior to elective surgery in all children with Trisomy-21. ⋯ Approximately half of the respondents would attempt to maintain the head and neck in a neutral position for either asymptomatic (42%) or symptomatic (55%) patients. We conclude that the majority of respondents base their preoperative evaluation of the cervical spine on the signs and symptoms of the patient. This is supported by the literature reviewed, but is contrary to the recommendations made in some case reports.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled analgesia following caesarean section under general anaesthesia: a comparison of fentanyl with morphine.
This prospective, randomised, double-blind study compared PCA fentanyl with PCA morphine for post-Caesarean section analgesia. Following a standardised general anaesthetic, 37 women were allocated to receive either fentanyl (n = 18) or morphine (n = 19). The PCA was commenced after the women had been made comfortable in the postanaesthetic recovery room with the appropriate opioid solution (mean dose required = fentanyl 375 micrograms or morphine 16 mg). ⋯ Both analgesic solutions provided effective analgesia for a mean of 37 hr with high levels of patient satisfaction, and there were no differences in VAS scores for pain and patient satisfaction, or for side effects (nausea, itch, and sleepiness) between fentanyl or morphine. However, more patients in the fentanyl group required supplementary boluses or alterations to the PCA settings (13/18 vs 4/19: P = 0.005), and one patient was removed from the study due to inadequate analgesia. We conclude that fentanyl is not recommended for routine PCA use following Caesarean section.

Randomized Controlled Trial Comparative Study Clinical Trial
The effect of isoflurane versus balanced anesthesia on rocuronium's pharmacokinetics and infusion requirement.
To compare the effects of two anesthetic techniques, balanced and isoflurane anesthesia, on the response to an intubating dose and an infusion of rocuronium, and on rocuronium's pharmacokinetics. ⋯ The similarity of response to an intubating dose and an infusion of rocuronium suggests that clinicians need not alter the dose or rate of rocuronium administration during isoflurane anesthesia with a of duration less than 1 hour. However, the greater clearance of rocuronium, in light of the similarity of infusion requirements, suggests that isoflurane potentiates rocuronium compared with balanced anesthesia.

Randomized Controlled Trial Clinical Trial
The effect of pre-operative oral fluids on morbidity following anaesthesia for minor surgery.
Postoperative morbidity and serum osmolality were studied in 46 patients who were encouraged to drink water until 3 h pre-operatively and 49 receiving the normal fasting regimen prior to minor surgery. There was significantly less thirst in the postoperative period in those patients allowed to drink and subjectively better recovery than after previous anaesthesia. There was no morbidity from ingestion of up to 11 of water 2.5 h pre-operatively. Although there was only a moderate improvement in postoperative recovery we feel that allowing patients to drink water pre-operatively improves patient comfort, especially since patients may have to fast for much longer than guidelines recommend, simply because of the traditional organisation of operating lists.
