Verification of an intravenous fluid warmer: A prospective, two-center observational trial.

Objectives: Avoiding inadvertent hypothermia during surgery is important. Intravenous fluid warmers used intraoperatively are critical for maintaining euthermia. We sought to prospectively evaluate the performance of the parylene-coated enFlow™ intravenous fluid warmer in patients undergoing surgery.

Reconstruction of missing channel in electroencephalogram using spatiotemporal correlation-based averaging.

Electroencephalogram (EEG) recordings often contain large segments with missing signals due to poor electrode contact or other artifact contamination. Recovering missing values, contaminated segments and lost channels could be highly beneficial, especially for automatic classification algorithms, such as machine/deep learning models, whose performance relies heavily on high-quality data. The current study proposes a new method for recovering missing segments in EEG.

Machine learning suggests sleep as a core factor in chronic pain.

Patients with chronic pain have complex pain profiles and associated problems. Subgroup analysis can help identify key problems. We used a data-based approach to define pain phenotypes and their most relevant associated problems in 320 patients undergoing tertiary pain management.

Validation of EQ-5D and 15D in the assessment of health-related quality of life in chronic pain.

Chronic pain has a significant impact on quality of life. Measurement of health-related quality of life (HRQoL) is essential in the assessment of pain management outcomes, but different instruments have produced varying results. We assessed the validity of 2 HRQoL instruments, EuroQol 5 dimensions questionnaire (EQ-5D) and 15-dimensional health-related quality of life measure (15D), in patients with challenging chronic pain.

Efficacy of thoracic epidural analgesia with or without intercostal nerve cryoanalgesia for postthoracotomy pain.

Background: We evaluated effects of thoracic epidural analgesia combined with intercostal nerve cryoanalgesia or epidural analgesia alone on acute and long-term pain after posterolateral thoracotomy.

Methods: Forty-two elective thoracotomy patients were randomly assigned to two groups, epidural combined with cryoanalgesia or epidural alone. A thoracic epidural catheter was inserted before induction of anesthesia.
