Dexmedetomidine and ketamine may be administered intraoperatively as continuous infusions to provide opioid-sparing anesthesia. Recent evidence has yielded controversial results regarding the impact of opioid-free anesthesia on postoperative complications, and there is a gap in knowledge regarding patient-reported outcomes (PROs). This study aimed to determine the impact of opioid-sparing anesthesia and opioid-based anesthesia on PROs among gynecologic patients within an enhanced recovery after surgery (ERAS) program. ⋯ In this single-center historical cohort study, opioid-sparing anesthesia had no significant or clinically important effects on interference with walking or other PROs in patients undergoing gynecologic surgery compared with opioid-based anesthesia. Opioid-sparing anesthesia was associated with less short-term opioid consumption than opioid-based anesthesia.

Observational Study
Changes in sensory block level during a programmed intermittent epidural bolus regimen for labour analgesia: a prospective observational cohort study.
In the context of a programmed intermittent epidural bolus (PIEB) regimen for labour analgesia, one can identify an upper sensory block level (USBL), defined as the highest dermatome with any altered sensation to cold, and a lower sensory block level (LSBL), defined as the highest dermatome with complete sensory block to cold. This study investigated whether and how these sensory block levels vary within PIEB cycles. ⋯ gov (NCT04716660); registered 21 January 2021.

The prone position can lead to anatomical compression of the thoracic cavity resulting in reduced cardiac output, especially in the context of chest wall deformities commonly present in patients with scoliosis. There are no protocols for using transesophageal echocardiography (TEE) to optimize prone positioning and for safe use of TEE during cases requiring neuromonitoring. ⋯ Patients with compliant chest walls or thoracic deformities are at risk of hemodynamic instability in the prone position. Intraoperative TEE can be used in the supine patient prior to proning to determine optimal longitudinal bolster positioning to minimize cardiac compression. Transesophageal echocardiography used during spine surgery in the prone position with neuromonitoring and motor-evoked potentials requires special considerations for patient safety.

Randomized Controlled Trial
Health economic evaluation alongside the Probiotics to Prevent Severe Pneumonia and Endotracheal Colonization Trial (E-PROSPECT): a cost-effectiveness analysis.
We sought to compare the cost-effectiveness of probiotics and usual care with usual care without probiotics in mechanically ventilated, intensive care unit patients alongside the Probiotics to Prevent Severe Pneumonia and Endotracheal Colonization Trial (PROSPECT). ⋯ gov (NCT01782755); registered 4 February 2013.
