Randomized Controlled Trial
Intraocular pressure and haemodynamic responses to insertion of the i-gel, laryngeal mask airway or endotracheal tube.
We hypothesised that the effects of insertion of an i-gel supraglottic airway management device on intraocular pressure (IOP) and haemodynamic variables would be milder than those associated with insertion of a laryngeal mask airway (LMA) or an endotracheal tube. ⋯ Insertion of the i-gel device provides better stability of IOP and the haemodynamic system compared with insertion of an endotracheal tube or LMA in patients undergoing elective non-ophthalmic surgery.

Both skin conductance and surgical stress index have been proposed as useful means of assessing pain. Both methods are based on the assessment of the sympathovagal balance, which, according to reports, is influenced by age and sex, and currently neither of the assessments take these factors into account. The aim of this study was to determine the relationship between age, sex, magnitude of acute post-operative pain and haemodynamic and autonomic changes. ⋯ Acute pain influences the sympathovagal balance. This response is significantly influenced by age and sex.
