The ability of alfentanil 15 micrograms kg-1 or 30 micrograms kg-1 to improve intubating conditions was studied in four groups of 25 ASA class 1 patients. Induction of anaesthesia was with thiopentone 5 mg kg-1. Neuromuscular blockade was induced with vecuronium using the priming principle. The priming dose, priming interval and intubating dose were 0.01 mg kg-1, 4 min, and 0.1 mg kg-1, respectively. Intubation was attempted 1 min after the intubating dose. Intubating conditions were judged unacceptable in about 30% of the patients belonging to the control groups. Alfentanil 15 micrograms kg-1, when administered 65 s before intubation, reduced the incidence of coughing and diaphragmatic movement (P less than 0.05) but did not reduce the incidence of overall unacceptable intubating conditions. Alfentanil 30 micrograms kg-1, however, reduced the incidence of vocal cord movement (P less than 0.005) as well as coughing and diaphragmatic movement (P less than 0.002). Alfentanil 30 micrograms kg-1 reduced the incidence of unacceptable intubating conditions from about 30% to 4% (P less than 0.02).

1. The onset of neuromuscular blockade following i.v. injection of atracurium 0.3, 0.4, or 0.5 mg/kg; vecuronium 0.08 or 0.1 mg/kg; and succinylcholine 1.0 mg/kg was studied in 205 adult patients during induction of anesthesia by means of the compound action potential (EMG) of the hypothenar muscle, which was indirectly stimulated via the ulnar nerve above the wrist, using the Datex Relaxograph. At the same time, the intubation conditions at 0.5, 1, 2, or 3 min after injection were assessed using a scoring system (Crul 1983) related to ease of laryngoscopy, movement of vocal cords and coughing, and reflex movements of the extremities. 2. Neuromuscular blockade and intubation conditions 2 min after administration of atracurium 0.3 mg/kg were 60 +/- 10% and 8.7 +/- 0.3; after 0.4 mg/kg 74 +/- 4% and 10.3 +/- 0.3; and after 0.5 mg/kg 86 +/- 5% and 11.8 +/- 0.2. After 0.08 mg/kg vecuronium 76 +/- 3% and 7.4 +/- 0.5 were recorded and after 0.1 mg/kg 85 +/- 6% and 10.5 +/- 0.4. Motor blockade 1 min after succinylcholine was 98 +/- 2% and intubation conditions scored 11.3 +/- 0.3. Relating intubation conditions to neuromuscular blockade yielded a close correlation and surprisingly good or very good intubation conditions (score more than 10) at a motor blockade of 80% (resp. 20% transmission). 3. Although succinylcholine is still the muscle relaxant with the most rapid onset of action, the new drug atracurium seems to satisfactorily facilitate tracheal intubation within an acceptably short time interval of 2 min after injection.(ABSTRACT TRUNCATED AT 250 WORDS)

Using two infusion anaesthesiamethods for laryngomicroscopy in 187 non-selected patients we studied the recovery phase with the aid of a special questionnaire filled in by the recovery room nurse. Premedication was with Thalamonal and atropine. Muscle relaxation was achieved by a succinylcholine drip. Induction doses: fentanyl 0.05-0.1 mg and thiopental 3-5 mg/kg bodyweight (Th-group) or diazepam 10-20 mg and ketamine 1 mg/kg bodyweight (K-group). Infusion doses: Thiopental 11.7 mg/min. (Th-group) or diazepam 0.2 mg/min. and ketamine 2 mg/min (K-group). Anaesthesia lasted for 20-30 min. We observed and noted during recovery: Breathing, cough-frequency and -quality, alertness, reaction to speech and stimulation, orientation, motor behaviour and well-being. Anaesthesia was sufficient in both groups. The patients of the K-group woke up earlier and their laryngeal reflexes seemed to stabilize quicker than in the Th-group. Because of the elevation of blood pressure caused by the stimulation of the laryngoscopy both methods are not recommended for patients at risk from high blood pressure.

We determine the feasibility of using the intubating laryngeal mask airway Fastrach (ILM) as a ventilatory device during emergence from anesthesia after use as an airway intubator in patients undergoing carotid endarterectomy. Thirty-five patients (ASA 2-3, 53-84 yr) were studied. Induction was with midazolam/fentanyl/etomidate and maintenance was with sevoflurane 1-2% in O2 33-50% and N2O. Neuromuscular blockade was with cisatracurium. Tracheal intubation was with a flexible lightwand via the ILM. After successful intubation, the ILM remained in the pharynx, but with the cuff deflated. After surgery, but before anesthesia was discontinued, baseline cardiovascular variables were recorded. The ILM cuff was then reinflated, the tracheal tube removed, the anesthesia breathing system connected to the ILM and anesthesia discontinued. Any changes in the cardiovascular variables greater than +/- 20% baseline values were noted from cuff reinflation to 1 minute after ILM removal. Any adverse respiratory (laryngospasm, coughing, gagging, stridor, SpO2 <94%, end-tidal carbon dioxide >45 mmHg, regurgitation/aspiration) or electrocardiographic (ST segment or rhythm changes) events were also noted. Patients were questioned about postoperative sore throat at 2 and 24 hr. ILM insertion and intubation through the ILM were successful in all patients. Adequate ventilation was achieved in all patients before intubation and after extubation. The mean (range) time taken from cuff reinflation to ILM removal was 9 (5-21) min. The rate pressure product remained within +/- 20% baseline values in all patients. There were no adverse respiratory or electrocardiographic events. There were no adverse neurological events. The surgical field was satisfactory. Postoperative sore throat occurred in 14% at 2 hr and 0% at 24 hr. We conclude that the ILM can be used as a ventilatory device for emergence from anesthesia after use as an airway intubator for carotid endarterectomy.
