Comparative Study[Course of the neuromuscular block under atracurium. Comparison with alcuronium].
Using a standardized anaesthetic protocol, the continuous monitoring of the twitch height after a 0.1 Hz stimulus was used to follow the evolution of curarization following injection of either atracurium (0.6 mg . kg-1) or alcuronium (0.2 mg . kg-1). The maximum twitch height inhibition was always greater than 99% of the control value and occurred after 107 +/- 50 s with atracurium (n = 30) and 172 +/- 120 s for alcuronium (n = 30) (p less than 0.02). ⋯ The spontaneous return to normal of the train of four was also significantly longer (p less than 0.001) for alcuronium: 118 +/- 23 min (n = 10) versus 69 +/- 7 min for atracurium (n = 10). The recovery index (the time required for twitch height to rise from 25% to 75%) was three times quicker (p less than 0.01) for atracurium (10 +/- 3 min; n = 10) than for alcuronium (30 +/- 13 min; n = 10).(ABSTRACT TRUNCATED AT 250 WORDS)

Intradermal testing is a valid manoeuvre for the determination of the drug responsible for an anaphylactoid reaction during anaesthesia. It does not fill criteria for a screening test and will have limited use in the preoperative diagnosis of anaesthetic allergy unless a high risk group is selected.

[Analgesia with an implanted device for repetitive intrathecal injections of morphine].
The use of intraspinal narcotics has been widely accepted as pain relief treatment for intractable cancer pain. Intraspinal low doses of morphine induce a potent selective long lasting analgesia. To avoid repetitive lumbar puncture, a drug delivery device was surgically implanted in 41 patients. ⋯ CSF leakage was noted in 11 patients; this was a challenge for us, as no other authors reported such a high rate for this complication. Aseptic meningitis was noted three times. In all cases but one, the symptoms resolved with appropriate treatment.

Comparative Study[Is automatic oscillometric measurement of blood pressure reliable in hypotension?].
The reliability of an automatic oscillometric device for measurement of blood pressure (BP) was assessed in a large range of BP values during intraoperative normotension and induced hypotension. Direct BP measurements were carried out with a radial catheter. Data were compared with those obtained with the oscillometric device placed on the opposite arm. ⋯ When BP values lower than 90 mmHg (12 kPa) for Pasys, 60 mmHg (8 kPa) for Padia and 70 mmHg (9,3 kPa) for Pa were considered individually, the correlation coefficients were 0.83, 0.73 and 0.77 respectively. These findings suggested that the oscillometric method can be considered as relatively suitable for monitoring moderate hypotension induced by vasodilators. The invasive technique must however remain the method of choice during profound hypotension.
