Thiopentone 4 mg/kg, Althesin 0.055 ml/kg and ketamine 2 mg/kg were compared in 157 children undergoing minor otolaryngological surgery, mostly adenotonsillectomy. Premedication was with pethidine and atropine and anaesthesia was maintained with nitrous oxide in oxygen and halothane. Tracheal intubation was facilitated with suxamethonium. In each group half of the children received pethidine 0.7 mg/kg after intubation and the remainder received saline. Ketamine increased arterial pressure after induction. The cardiovascular responses to intubation were more obvious after thiopentone and Althesin than after ketamine. Operating conditions, cardiovascular changes during operation and the course of extubation were similar in all groups. The recovery after ketamine was longer than after thiopentone and Althesin. Thiopentone was associated with significantly less vomiting immediately after operation than was Althesin and ketamine. In the period immediately after operation Althesin was associated with a higher need for analgesics compared with thiopentone and ketamine. Pethidine prolonged the recovery after thiopentone, decreased the incidence of vomiting immediately after operation associated with Althesin and increased that associated with ketamine.

Clinical observations during anaesthesia and intubation of emergency patients are presented showing a differentiated impact of etomidate (Hypnomidate) on upper airway reflexes: a blockade of pharyngeal reflexes with sustained but possibly delayed laryngeal reflexes and a certain protection against laryngospasm and vomiting. In addition etomidate enables, preferably in combination, difficult intubation with sustained spontaneous breathing due to its low respiratory depressant effect. These features were confirmed in a small foreshortened clinical study using thiopentone (Trapanal) or etomidate without muscle relaxants, whereby the difference in high risk patients became obvious. The impact of anaesthetics on airway reflexes is generally concealed by muscular relaxants, and observations on this matter are difficult to make subject to quantifiable parameters and controlled studies; accordingly such observations are scarcely found in newer anaesthetic literature. In the development of new techniques for intubation and anaesthesia without muscle relaxation, these methodical problems deserve attention.

Two anaesthetic procedures that did not include nitrous oxide were compared in a randomised study of 50 patients for tympanoplasty and tympanoscopy: propofol given for induction and maintenance, and thiopentone-isoflurane given for induction and maintenance, respectively. Induction in the first group was with a bolus injection of propofol and the same agent was given for the duration of anaesthesia by continuous intravenous administration. Thiopentone was given until loss of the eyelash reflex and anaesthesia maintained with isoflurane 0.4-2.0%. Analgesia was achieved in both groups by fentanyl given intravenously and by local injection of mepivacaine with ornipressin. The two patient groups were analysed for age, sex and weight as well as for side effects during the induction, maintenance and recovery periods, such as coughing, vomiting, venous pain, spontaneous movements, singultus, headaches, dysrhythmias and psychic disorders possibly due to anaesthesia. Side effects were moderate in both groups. Recovery time was statistically significantly shorter in the propofol group and the patients in this group appeared to be much more aware after recovery than those in the thiopentone-isoflurane group.

Propofol anaesthesia may reduce postoperative emesis. The purpose of this study was to compare the incidence of emesis after propofol anaesthesia with and without nitrous oxide, compared with thiopentone and halothane anaesthesia, in hospital and up to 24 hr postoperatively, in outpatient paediatric patients after strabismus surgery. Seventy-five ASA class I or II, unpremedicated patients, aged 2-12 yr were randomly assigned to one of three groups: Thiopentone, 6.0 mg.kg-1 i.v. induction followed by halothane and N2O/O2 for maintenance (T/H); propofol for induction, followed by propofol and oxygen for maintenance (P/O2); and propofol for i.v. induction, followed by propofol infusion and N2O/O2 for maintenance (P/N2O). All received vecuronium, controlled ventilation, and acetaminophen pr. Morphine was given as needed for postoperative analgesia. There were no differences in age, weight, number of eye muscles operated upon, duration of anaesthesia or surgery. The P/N2O group (255 +/- 80 micrograms.kg-1 x min-1) received less propofol than the P/O2 group (344 +/- 60 micrograms.kg-1 x min-1) (P < or = 0.0001) and had shorter extubation (P < 0.001) and recovery (P < 0.01) times. Emesis in the hospital, in both the P/N2O (4.0%) and P/O2 group (4.0%) was less than in the T/H group (32%) (P < 0.01). Antiemetics were required in four patients in the T/H group (16.0%). Overall emesis after surgery was not different among the groups: T/H (48%), P/O2 (28%) and P/N2O (42%). The use of propofol anaesthesia with and without N2O decreased only early emesis. This supports the concept of a short-acting, specific antiemetic effect of propofol.
