Obesity is an epidemic in much of the Western World. The extent of this problem, combined with the increasing preference for ambulatory surgical procedures, has produced a difficult situation for many anaesthesiologists. ⋯ Patients with OSA are often not ideal candidates for certain day-case procedures, but many outpatient procedures can be performed on patients with OSA as long as attention is paid to anaesthetic technique. Diabetic patients are prone to numerous complications in the perioperative period, including cardiac problems, but with careful management, they are able to undergo day-case surgical procedures safely.

Randomized Controlled Trial Comparative Study
Randomized crossover comparison between the i-gel and the LMA-Unique in anaesthetized, paralysed adults.
The i-gel differs from other supraglottic airway devices, in that it has a softer, non-inflatable cuff. This study was designed to compare the performance of the i-gel and the LMA-Unique (LMA-U) when used during anaesthesia in paralysed patients. ⋯ We found no difference in leak pressures and success rate of first-time insertion between the i-gel and the LMA-U. Time to successful insertion was significantly shorter for the i-gel. We conclude that the i-gel provides a reasonable alternative to the LMA-U for controlled ventilation during anaesthesia.

Randomized Controlled Trial Multicenter Study
Prospective randomized controlled multi-centre trial of cuffed or uncuffed endotracheal tubes in small children.
The use of cuffed tracheal tubes (TTs) in small children is still controversial. The aim of this study was to compare post-extubation morbidity and TT exchange rates when using cuffed vs uncuffed tubes in small children. ⋯ The use of cuffed TTs in small children provides a reliably sealed airway at cuff pressures of

Randomized Controlled Trial
Magnesium sulphate has beneficial effects as an adjuvant during general anaesthesia for Caesarean section.
The use of low concentrations of volatile anaesthetics with avoidance of opioids may induce intraoperative awareness and adverse haemodynamic responses during Caesarean section. Magnesium is well known to reduce anaesthetic requirements and to block noxious stimuli. We investigated whether i.v. magnesium sulphate modulates anaesthetic depth and analgesic efficacy during Caesarean section. ⋯ Preoperative i.v. magnesium sulphate attenuated BIS and arterial pressure increases during the pre-delivery period. Magnesium sulphate can be recommended as an adjuvant during general anaesthesia for Caesarean section to avoid perioperative awareness and pressor response resulting from inadequate anaesthesia, analgesia, or both.

Comparative Study
Determination of serum propofol concentrations by breath analysis using ion mobility spectrometry.
We aimed to measure propofol concentrations in exhaled air with an ion mobility spectrometer coupled to a multicapillary column for pre-separation (MCC-IMS). In addition, we aimed to compare the values of these measurements with serum propofol concentrations, as determined by gas chromatography-mass spectrometry (GC-MS). ⋯ MCC-IMS may be a suitable method to determine propofol concentrations in exhaled air, and may be used to predict propofol concentrations in serum.
