Morbidly obese patients present with excess fatty tissue externally on the breast, neck, thoracic wall and abdomen and internally in the mouth, pharynx and abdomen. This excess tissue tends to make access (intubation, tracheostomy) to and patency (during sedation or mask ventilation) of the upper airway and the function of the lungs (decreased residual capacity and aggravated ventilation perfusion mismatch) worse than in lean patients. Proper planning and preparation of airway management is essential, including elevation of the patient's upper body, head and neck. ⋯ It is important to ensure sufficient depth of anaesthesia before initiating manipulation of the airway because inadequate anaesthesia depth predisposes to aspiration if airway management becomes difficult. The intubating laryngeal mask airway is more efficient in the morbidly obese patients than in lean patients and serves as a rescue device for both failed ventilation and failed intubation. In the 24 h following anaesthesia, morbidly obese patients experience frequent oxygen desaturation periods that can be counteracted by continuous positive airway pressure, noninvasive ventilation and physiotherapy.

Randomized Controlled Trial Comparative Study
Comparison of sevoflurane volatile induction/maintenance anaesthesia and propofol-remifentanil total intravenous anaesthesia for rigid bronchoscopy under spontaneous breathing for tracheal/bronchial foreign body removal in children.
Foreign body aspiration is a life-threatening condition, with children under 3 years of age most at risk. This study was designed to compare the clinical characteristics of sevoflurane volatile induction/maintenance anaesthesia (VIMA) and propofol-remifentanil total intravenous anaesthesia (TIVA) for children undergoing rigid bronchoscopy under spontaneous breathing for tracheal/bronchial foreign body removal. ⋯ Compared with propofol-remifentanil TIVA, sevoflurane VIMA provides more stable haemodynamics and respiration, faster induction and recovery and higher incidence of excitement in paediatric patients undergoing tracheal/bronchial foreign body removal under spontaneous breathing.

Randomized Controlled Trial Comparative Study
Comparison of TruView EVO2 with Miller laryngoscope in paediatric patients.
Except for neonates and specific malformations in children, management of the paediatric airway is not a major problem for the anaesthetist. Miller laryngoscope was traditionally used for paediatric intubation. The TruView EVO2 system is a recently introduced device with a unique blade that provides a wide and magnified laryngeal view. ⋯ The results suggest that when compared with the Miller laryngoscope, the TruView EVO2 laryngoscope appears to improve the view of the larynx but requires a longer time for tracheal intubation. The IDS scores were similar; thus, the TruView EVO2 laryngoscope can be a good alternative to traditionally used Miller laryngoscope.

Randomized Controlled Trial
Flumazenil expedites recovery from sevoflurane/remifentanil anaesthesia when administered to healthy unpremedicated patients.
To investigate the hypothesis that 0.3 mg flumazenil administered to healthy unpremedicated patients at the end of deep surgical sevoflurane/remifentanil anaesthesia would expedite recovery. Flumazenil, an imidazobenzodiazepine derivative, antagonizes the hypnotic/sedative effects of benzodiazepines on γ-aminobutyric acid receptors. However, endogenous benzodiazepine ligands (endozepines) were isolated in mammalian tissues of individuals who had not received benzodiazepines. ⋯ Administration of a single dose of 0.3 mg flumazenil to healthy unpremedicated patients at the end of sevoflurane/remifentanil anaesthesia results in earlier emergence from anaesthesia and significantly expedites recovery. This could redefine the role of flumazenil in general anaesthesia, implicating endozepine-dependent mechanisms.
