Historical Article
Oropharyngeal and nasopharyngeal airways: I (1880-1995).
During the past decade the laryngeal mask airway (LMA) has dominated literature about airways for use during general anaesthesia. The LMA addresses clearly defined clinical objectives. The purpose of this study is to determine whether those objectives were described collectively with reference to earlier airway designs. ⋯ The design of airways has been based on clinical circumstances and perceived requirements of the time. In contemporary anaesthetic practice, distinct clinical situations still occur and there is a role for different device designs. Currently for supraglottic airway management during general anaesthesia, four types of airway should be available: a Guedel airway, nasopharyngeal airway, a laryngeal mask airway, and an airway specifically designed to facilitate blind tracheal intubation.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of propofol versus thiopentone with midazolam or lidocaine to facilitate laryngeal mask insertion.
To assess the ease of insertion of laryngeal mask airway (LMA) comparing propofol with lidocaine or midazolam followed by thiopentone and compare the costs with each technique. ⋯ With the above doses, a fentanyl-midazolam-thiopentone combination which is about 35% less expensive than fentanyl-propofol, provides equally good conditions for the insertion of LMA.

Randomized Controlled Trial Comparative Study Clinical Trial
Preoperative ketorolac increases bleeding after tonsillectomy in children.
To compare the incidence of vomiting following codeine or ketorolac for tonsillectomy in children. ⋯ Preoperative ketorolac increases perioperative bleeding among children undergoing tonsillectomy without beneficial effects.
