Randomized Controlled Trial
Systemic administration of lidocaine reduces morphine requirements and postoperative pain of patients undergoing thoracic surgery after propofol-remifentanil-based anaesthesia.
Remifentanil is being increasingly used as an analgesic in fast-track surgery, but severe postoperative pain may happen occasionally. In this study, we evaluated the effects of systemic administration of lidocaine on postoperative pain and morphine requirements after propofol-remifentanil-based anaesthesia. ⋯ Systemic administration of lidocaine could reduce morphine requirements, postoperative pain and intraoperative propofol C(e) of patients undergoing thoracic surgery after propofol-remifentanil-based anaesthesia.

The usefulness of the laryngeal mask airway Fastrach for laryngeal surgery.
Suspension laryngoscopy under general anaesthesia with a tracheal tube has been widely used for laryngeal microsurgery, but it has some limitations such as intense cardiovascular stimulation during anaesthesia of short duration, occasionally a poor surgical field, and the possibility of a mass being hampered by the tracheal tube. The aim of this study was to compare the usefulness of the laryngeal mask airway (LMA) Fastrach and fibreoptic bronchoscope with a conventional suspension laryngoscope in laryngeal microsurgery. ⋯ The LMA Fastrach during fibreoptic bronchoscope-guided laryngeal surgery provided a good surgical field and haemodynamic stability without additional risk compared with the conventional suspension laryngoscope.

The effectiveness of dexmedetomidine infusion for sedating oral cancer patients undergoing awake fibreoptic nasal intubation.
Dexmedetomidine is characterized with effects of sedation, analgesia, amnesia and lack of respiratory depression. Hence, it should be suitable for awake fibreoptic intubation (AFOI). ⋯ Combination of dexmedetomidine loading with topical anaesthesia provides significant benefit for AFOI in intubation condition, patient tolerance, haemodynamic response, amnesia and satisfaction. Dexmedetomidine is effective for AFOI in anticipated difficult airway with only minor and temporary haemodynamic adverse effects.

Learning fibreoptic intubation with a virtual computer program transfers to 'hands on' improvement.
Fibreoptic intubation is an essential skill in anaesthesiology that is challenging to learn in the clinical setting. The goal of this study was to evaluate 'virtual fibreoptic intubation' (VFI) software as an adjunct to the traditional fibreoptic intubation teaching. ⋯ Self-training in fibreoptic intubation with the VFI software may improve the acquisition of fibreoptic intubation skills.

Randomized Controlled Trial
Laryngeal mask airway vs. uncuffed endotracheal tube for nasal and paranasal sinus surgery: paediatric airway protection.
Risks are anticipated for laryngeal mask airway (LMA) anaesthesia during nasal and sinus surgeries because blood can trickle posteriorly into the hypopharynx and contaminate the airway. This study was conducted to determine whether a LMA could provide adequate airway protection from the expected intraoperative bleeding. ⋯ LMA is a suitable method for paediatric patients undergoing sinonasal surgery because it offers airway protection from blood contamination comparable to that of a standard uncuffed ETT with throat pack.
