Observational Study
Cardiopulmonary exercise variables are associated with postoperative morbidity after major colonic surgery: a prospective blinded observational study.
Postoperative complications are associated with reduced fitness. Cardiopulmonary exercise testing (CPET) has been used in risk stratification. We investigated the relationship between preoperative CPET and in-hospital morbidity in major colonic surgery. ⋯ CPET variables are associated with postoperative morbidity. A multivariable model with VO₂ at θ(L) and gender discriminates those with complications after colonic surgery.

Supraglottic airways (SGAs) have an established role in airway management of difficult airways in both adults and children. However, there are limited data regarding the use of SGAs for primary airway management in children. The aim of this study is to assess the success rates and adverse events related to the use of SGAs for primary airway management during anaesthesia in children with difficult airways. ⋯ SGAs can be effectively utilized for airway maintenance in the paediatric difficult airway population.

Observational Study
Age-related changes in EEG power spectra in infants during sevoflurane wash-out.
Few electroencephalography (EEG) data are available in anaesthetized infants. This study aimed to identify EEG characteristics that might warn of awakening (AW) from sevoflurane anaesthesia in infants. ⋯ During sevoflurane wash-out, decreasing P5-20 Hz might warn of impending AW in infants >3 months old, but not in younger infants.

Observational Study
Respiratory stroke volume variation assessed by oesophageal Doppler monitoring predicts fluid responsiveness during laparoscopy.
This study was designed to assess the ability of the stroke volume respiratory variation (ΔrespSV) determined by oesophageal Doppler monitoring (ODM) to predict the response to volume expansion (VE) during pneumoperitoneum. The predictive value of ΔrespSV was evaluated according to the concept of the 'grey zone'. ⋯ ΔrespSV and ΔrespPV predicted fluid responsiveness during laparoscopy under strict physiological conditions. FTc was not predictive of fluid responsiveness during laparoscopy.
