Chronic postoperative pain is a well-recognized problem after various types of surgery such as amputation, thoracotomy, mastectomy, gallbladder surgery and inguinal hernia repair. However, little is known about chronic pain after gynaecologic surgery. Therefore, the aim was to study the incidence of chronic pain after Caesarean section. ⋯ Chronic pain after Caesarean section seems to be a significant problem in at least 5.9% of patients.

Case Reports Clinical TrialReduction in the incidence of awareness using BIS monitoring.
Explicit recall (ER) is evident in approximately 0.2% of patients given general anaesthesia including muscle relaxants. This prospective study was performed to evaluate if cerebral monitoring using BIS to guide the conduction of anaesthesia could reduce this incidence significantly. ⋯ The use of BIS monitoring during general anaesthesia requiring endotracheal intubation and/or muscle relaxants was associated with a significantly reduced incidence of awareness as compared with a historical control population.

Multicenter Study Clinical TrialAge-related effects in the EEG during propofol anaesthesia.
Age-related differences in the spectral composition of the EEG in induction and emergence times, and in drug consumption during propofol anaesthesia were investigated. ⋯ Older patients differ from younger ones regarding the hypnotic effect of propofol and the spectral patterns in the EEG. For an efficient automatic assessment of the EEG during anaesthesia a multivariable approach accounting for age-effects is indispensable.

This editorial accompanied the 2004 study from Ekman, the first published evidence showing a reduction in awareness when BIS monitoring is used to monitor depth of anaesthesia.
Ekman’s findings were shortly after confirmed by Myles et al. in their landmark 2004 B-Aware Trial.
This editorial and the two related studies are well worth reading to give historical context to the emergence of reliable depth-of-anaesthesia monitors.

Randomized Controlled Trial Clinical TrialPropofol and remifentanil for intubation without muscle relaxant: the effect of the order of injection.
Common practice in intubation without muscle relaxant is to inject the opioid drug prior to the hypnotic drug. Because remifentanil reaches adequate cerebral concentration more rapidly than does propofol, we tested the hypothesis that injection of remifentanil after propofol might lead to better intubating conditions. ⋯ We therefore conclude that in premedicated healthy patients with no anticipated risk of difficult intubation, intubating and haemodynamic conditions are better when remifentanil is injected after propofol.
