Randomized Controlled TrialThe comparison of the analgesic efficacy of continuous paravertebral block alone compared with continuous paravertebral and intercostal nerve block for thoracotomy in adults: a randomized controlled trial.
The study aims to compare the analgesic efficacy of two analgesic interventions, continuous paravertebral (PVB) nerve block alone with continuous paravertebral and intercostal nerve block (PVB/ICB) in patients undergoing thoracotomy. ⋯ Clinicaltrails.gov NCT04715880.

Randomized Controlled TrialComparison of the effect of sevoflurane and propofol on the optic nerve sheath diameter in patients undergoing middle ear surgery.
During middle ear surgery, the patient's head is turned away from the surgical site, which may increase the intracranial pressure. Anesthetics also affect the intracranial pressure. The optic nerve sheath diameter (ONSD) measured using ultrasonography is a reliable marker for estimating the intracranial pressure. This aim of this study was to investigate the effect of sevoflurane and propofol on the ONSD in patients undergoing middle ear surgery. ⋯ The ONSD was significantly increased during middle ear surgery. No significant difference was observed in the amount of ONSD increase between the sevoflurane and propofol groups.

Effects of the attachment method of the stimulating electrodes Nihon-Kohden NM-345Y™ and changes in forearm position on stimulus current values during calibration in electromyography-based neuromuscular monitoring: a single-center experimental study.
The traditionally recommended method for attaching electromyography (EMG) electrodes (NM-345Y™) during EMG-based neuromuscular monitoring developed by Nihon-Kohden may decrease the monitoring accuracy when forearm limb position changes. This study investigated methods for attaching stimulating electrodes that maintained stable EMG-based neuromuscular monitoring accuracy, regardless of forearm limb position changes. ⋯ Crossing the ulnar nerve with the line connecting the anode and cathode of the stimulating electrodes may stabilize EMG-based neuromuscular monitoring accuracy.

Influence of the Pringle maneuver during partial hepatectomy on the neuromuscular block induced by intermittent and continuous dosing of rocuronium.
The Pringle maneuver (PM) is a common procedure in hepatectomy that is known to interrupt drug elimination. The purpose of this study was to examine the influence of PM on the duration of action of rocuronium administered by intermittent bolus dosing, the continuous rocuronium infusion dose required for maintenance of a moderate neuromuscular block, and changes in plasma concentrations of rocuronium. ⋯ Rocuronium-induced neuromuscular block is significantly augmented during PM. However, the augmentation is not associated with an increase in plasma rocuronium concentration.

Association between Oxygen Reserve index and arterial partial pressure of oxygen during one-lung ventilation: a retrospective cohort study.
We aimed to investigate the association between the Oxygen Reserve index (ORi) and arterial partial pressure of oxygen (PaO2) during one-lung ventilation in patients who underwent non-cardiac thoracic surgery requiring one-lung ventilation. ⋯ This study suggested that ORi could provide useful information on arterial oxygenation even during one-lung ventilation for non-cardiac thoracic surgery.
