Fixed-rate alfentanil infusions for surgery of variable duration.
The continuous infusion of alfentanil with a modified Fresenius-injectomat infusion pump was studied in 27 patients undergoing orthopaedic operations of variable length. Patients were premedicated with diazepam 10 mg orally. Anaesthesia was induced with thiopentone, vecuronium and an anfentanil loading dose delivered by the infusion pump at a rate of 10 micrograms kg-1 min-1 for 10 min. ⋯ Recovery was uneventful in all but one patient, who had ventilatory depression that responded to naloxone. All patients were satisfied with their anaesthesia and recovery. The use of a 10-min, 10 micrograms kg-1 min-1 loading infusion, then a maintenance infusion of 1 microgram kg-1 min-1 delivered by a modified Fresenius-injectomat infusion pump may be the first step in simplifying the continuous infusion of alfentanil.

[Recovery after anesthesia with propofol in otorhinolaryngologic surgery of brief duration].
This study was designed to assess recovery from total intravenous anaesthesia with propofol for short ENT procedures. Twenty-six patients (ASA I and II) were assigned to two groups of thirteen: one breathed air (Laser laryngeal microsurgery), the second N2O-O2 (FIO2 : 0.5) (various ENT procedures). The induction sequence was exactly the same for both groups: oral premedication with 10 mg diazepam one hour before surgery, I mg pancuronium bromide, 2 micrograms X kg-1 fentanyl, denitrogenation within 3 min, after which propofol was delivered (2.5 mg X kg-1). ⋯ Thus, the total dose of propofol was significatively different between the two groups: 24.5 +/- 6.7 mg X kg-1 X h-1 in group "air" versus 16 +/- 3.6 mg X kg-1 X h-1 in group "N2O-O2" (p less than 0.001). Extubation occurred within 16 +/- 8 min in group "air", being more rapid in group "N2O-O2" (11 +/- 9 min; no significant difference). Recovery was assessed with two psychomotor tests: choice reaction time (CRT) and tracing test (TT).(ABSTRACT TRUNCATED AT 250 WORDS)

A number of obstetric fatalities related to epidural anaesthesia have been reported recently. In each case catheter or needle misplacement had resulted in a lethal intrathecal or intravascular injection. In this review these cases and a number of other similar but nonfatal reports are examined. ⋯ A detailed test dose protocol is recommended, which will safely warn of epidural catheter and needle misplacement in the most effective manner possible. If the protocol is used, accidental subarachnoid and intravascular injections can be reduced to a minimum, but they will still occur. It is emphasised that these complications should not cause fatalities if trained personnel and adequate resuscitation facilities are available.
