Randomized Controlled Trial Comparative Study Clinical Trial
Duration of apnoea with two different intubating doses of remifentanil.
We have studied the apnoea time after induction with two successful drug intubating regimes, both containing remifentanil. Group 1 (n = 20); propofol 2 mg kg-1 and remifentanil 2 micrograms kg-1 and group 2 (n = 20); propofol 2 mg kg-1, remifentanil 1 microgram kg-1 and lignocaine 1 mg kg-1. Intubation was possible in all 40 patients, and regarded as acceptable in 90% and 85% of patients, respectively. ⋯ Similarly, there was a decrease in arterial pressure after induction in both groups (P < 0.05), but this was not deemed to be clinically significant. Only two patients in each group required ephedrine 6 mg before arterial pressure was restored to within 25% of the base-line. Intubating conditions were similar in both groups, but group 2 provided a significantly shorter apnoea time.

Randomized Controlled Trial Comparative Study Clinical Trial
Remifentanil vs. fentanyl during interventional rigid bronchoscopy under general anaesthesia and spontaneous assisted ventilation.
The treatment of tracheo-bronchial diseases with rigid bronchoscopy requires general anaesthesia without tracheal intubation. Spontaneous assisted ventilation is a safe modality of ventilation. In this study the use of remifentanil and fentanyl is compared during rigid bronchoscopy with spontaneous assisted ventilation. ⋯ In conclusion, the use of remifentanil during rigid bronchoscopy under general anaesthesia with spontaneous assisted ventilation is safe and assures good operating conditions. Moreover, remifentanil permits a more rapid recovery than fentanyl. The dose of remifentanil is higher than previously described for spontaneously breathing patients.

Computed tomographic epidurography: an aid to understanding deformation of the lumbar dural sac by epidural injections.
Local anaesthetics injected into the epidural space may deform the dural sac to a variable degree, thereby contributing to variability in the extent of the block. We investigated deformation of the lumbar dural sac after injection into the lumbar epidural space. The subjects were 26 patients with low-back pain who underwent lumbar epidurography and computed tomographic (CT) epidurography, of whom seven also underwent myelography and computed tomographic myelography. ⋯ This line was though to be a manifestation of the dural deformation to the inverted triangle. Dural sac deformation usually shows a specific pattern, although there are individual variations. Dural deformability is an important consideration in any analysis of the spread of epidural block or of the changes of epidural pressure after epidural injection of local anaesthetics.

Randomized Controlled Trial Clinical Trial
An assessment of prochlorperazine buccal for the prevention of nausea and vomiting during intravenous patient-controlled analgesia with morphine following abdominal hysterectomy.
The effectiveness of prochlorperazine buccal as an anti-emetic for the prevention of post-operative nausea and vomiting in patients using intravenous patient-controlled analgesia with morphine following abdominal hysterectomy has been assessed in a randomized, double-blind, placebo-controlled study. Forty-nine female patients participated with 26 allocated to the prochlorperazine buccal group and the remainder to the placebo group. Each received either placebo or prochlorperazine buccal 6 mg, in each case by the buccal route, 1 h prior to anaesthesia with further doses at 6, 18, 30 and 42 h, respectively. ⋯ Intravenous droperidol is the current gold standard prophylactic anti-emetic in post-operative nausea and vomiting associated with intravenous patient controlled analgesia with morphine usage. This study has demonstrated a peri-operative prochlorperazine buccal regimen to be effective in post-operative nausea and vomiting prophylaxis in the use of intravenous patient controlled analgesia with morphine. Prochlorperazine buccal should be considered as an effective, inexpensive option for the prevention of post-operative nausea and vomiting in post-operative intravenous patient controlled analgesia with morphine administration.
