Study of penehyclidine for the prevention of postoperative nausea and vomiting following laparoscopic sleeve gastrectomy under general anesthesia: a randomized, prospective, double-blind trial.
To investigate the efficacy of penehyclidine (PHC) for preventing postoperative nausea and vomiting (PONV) after laparoscopic sleeve gastrectomy (LSG) under general anesthesia. ⋯ PHC effectively prevented PONV occurrence and reduced its severity in LSG patients without decreasing postoperative recovery outcomes, particularly in the infusion cohort.

Margin of safety for needle puncture of a radial artery in children: Recommendation for ultrasound-guided cannulation.
The radial artery is commonly selected for arterial puncture and cannulation, but radial nerve palsy may occur. To minimize possible damage to the nerve, needle puncture should be made within the margin of safety (between the wrist to the distal end of the radial artery and the radial nerve running in parallel). In adults, the margin of safety for radial artery puncture is approximately 6.8 cm from the wrist in men and approximately 5.4 cm in women, but the margin of safety is not known in children of different age groups. ⋯ jRCT1032230243.

Ultrasound assessment of the frequency and variation of arteries in the interscalene region.
Given the abundance of arteries in the neck, a significant risk of puncturing arteries exists when performing a brachial plexus block. Therefore, it is important to confirm the presence of arteries when performing a brachial plexus block via the interscalene approach. This study aimed to investigate the frequency and variations of arteries in the interscalene region in healthy Japanese adults using ultrasonography. ⋯ Interscalene observations using ultrasound devices revealed a high artery frequency, with numerous topographic variations.

Preoperative hypoxic biomarkers and postoperative delirium in patients with obstructive sleep apnea.
Postoperative delirium (POD) in patients with obstructive sleep apnea (OSA) is associated with increased mortality and healthcare costs. In this study, we investigated the association of OSA risk, serum biomarkers for central nervous ischemia (S100B and NSE), and POD. ⋯ We found a trend of decreasing POD incidence with increasing OSA risk, which was not robust in a complete case analysis. Our results possibly support the phenomenon of hypoxic preconditioning.
