Randomized Controlled Trial
The effects of Valsalva manoeuvres on venepuncture pain.
Stimulating the vagus nerve reduces pain. The purpose of this study was to evaluate the effect of a Valsalva manoeuvre, which stimulates the vagus nerve, on perception of pain during peripheral venous cannulation in adult patients. ⋯ On the basis of data from this study, the Valsalva manoeuvre may be of the value before venous cannulation as a simple and practical method to reduce pain from venous cannulation.

Inaccurate measurements of body temperature following cardiopulmonary bypass may be associated with serious complications. The purpose of this study was to determine whether axillary and tympanic temperature measurements correlate with the urinary bladder temperature in the early postcardiac surgery period. ⋯ The axilla and tympanic membrane are unreliable sites for core body temperature measurement early after cardiopulmonary bypass in adult patients and clinical decisions should be based on more reliable methods.

The GlideScope is a new video laryngoscope. The aim of our study was to assess its use compared to a Macintosh blade in airway scenarios on the Airman airway simulator. The scenarios were: 'normal' or resting state of the manikin, pharyngeal obstruction, cervical rigidity and tongue oedema. ⋯ The GlideScope improved the view in one of three difficult airway situations when used by anaesthetists with no formal training in its use. No single airway device offers a solution to all scenarios, however, we consider that the GlideScope is a useful addition to the range of difficult airway devices available.

Randomized Controlled Trial Comparative Study
Comparison of haemodynamic responses to orotracheal intubation with GlideScope videolaryngoscope and fibreoptic bronchoscope.
The GlideScope videolaryngoscope is a newly developed laryngoscope for tracheal intubation recently introduced into clinical anaesthesia. In this randomised clinical study, we compared the haemodynamic responses to orotracheal intubation using a GlideScope videolaryngoscope and a fibreoptic bronchoscope. ⋯ The orotracheal intubations using a fibreoptic bronchoscope and a GlideScope videolaryngoscope produce similar haemodynamic responses.

Randomized Controlled Trial
The effect of epidural bupivacaine on maintenance requirements of sevoflurane evaluated by bispectral index in children.
Combined (local and general) anaesthesia or Balanced (intravenous analgesics and inhalational hypnotics) anaesthesia are commonly used in paediatrics. The authors have investigated the influence of both types of anaesthesia on the requirements of sevoflurane to maintain an adequate level of hypnosis as measured by Bispectral index (at around 50) monitoring in paediatric orthopaedic patients. ⋯ Combined anaesthesia with epidural bupivacaine maintains the same Bispectral index values as Balanced anaesthesia during orthopaedic surgery in children without fentanyl and with a lower sevoflurane requirement.
