Randomized Controlled Trial Clinical TrialIntubating conditions provided by propofol and alfentanil--acceptable, but not ideal.
The use of muscle relaxants to facilitate intubation is associated with several side effects regardless of whether depolarizing or non-depolarizing drugs are used. In the present study we compared the intubating conditions, haemodynamic responses and changes in oxygen saturation following induction with alfentanil and propofol or alfentanil, thiopental and suxamethonium. ⋯ The results show that propofol and alfentanil in combination provides haemodynamic stability and unaltered oxygen saturation but less optimal intubating conditions.

Randomized Controlled Trial Comparative Study Clinical TrialDoes propofol reduce vomiting after strabismus surgery in children?
Previous studies have indicated that propofol anaesthesia may reduce the incidence of postoperative nausea and vomiting after strabismus surgery in children. This study was designed to investigate the incidence of vomiting after strabismus surgery at two different levels of propofol anaesthesia compared to thiopental/isoflurane anaesthesia. ⋯ In the present study, propofol anaesthesia compared to thiopental/isoflurane anaesthesia did not reduce the incidence of vomiting following strabismus surgery in children.

Case ReportsIncidence of awareness in total i.v. anaesthesia based on propofol, alfentanil and neuromuscular blockade.
There is no reliable technique for monitoring drug concentrations in total i.v. anaesthesia (TIVA) with muscle relaxation. An increased risk of awareness with TIVA has been stated as a possible drawback. The present study was conducted in order to assess the incidence of conscious awareness in TIVA based on propofol, alfentanil and neuromuscular blockade. ⋯ If the true incidence of conscious awareness is to be determined, interviews must be extended beyond the first postoperative day. Our study indicates that if appropriate dosing of propofol and alfentanil are adhered to, and proper action is taken in case of haemodynamic alterations suggestive of inadequate anaesthesia, the incidence of conscious awareness in non-cardiac TIVA with neuromuscular blockade is low.

Case ReportsManagement of the difficult airway. A case of failed fiberoptic intubation.
Fiberoptic intubation is the current gold standard for the management of difficult intubation. Nevertheless, in rare circumstances even fiberoptic intubation fails. ⋯ This case illustrates that even awake fiberoptic intubation has its failure rate, due to inability to visualize the larynx, inability to advance the tube over the fiberscope (as in the present case), or inability to direct the tube towards the larynx. Due to the extreme deviation of the larynx other established techniques for difficult intubation were not deemed appropriate in this case. Therefore, weighing the risks and benefits, a decision was made to perform a tracheotomy under local anaesthesia.

Case ReportsAnaphylactic shock following intravenous administration of lignocaine.
A 26-year-old female, presenting for dental surgery, developed anaphylactic shock immediately after intravenous administration of lignocaine without preservative added to the propofol to alleviate pain during intravenous injection. We describe the clinical circumstances, the management and the investigations carried out to detect the cause.
