Effects of depth of neuromuscular block on postoperative pain during laparoscopic gastrectomy: A randomised controlled trial.

Background: Evidence on whether the use of deep neuromuscular block (NMB) influences postoperative pain after laparoscopic surgery is limited, and existing studies have shown conflicting results. We studied the effect of the depth of NMB during laparoscopic gastrectomy on postoperative pain.

Objective: The aim of this study was to evaluate the effect of depth of NMB during laparoscopic gastrectomy on postoperative pain by allocating patients randomly to either deep or moderate NMB with a standard-pressure pneumoperitoneum.

Quantitative analysis of the effect of end-tidal carbon dioxide on regional cerebral oxygen saturation in patients undergoing carotid endarterectomy under general anaesthesia.

Aims: Regional cerebral oxygen saturation (rSO ) is currently the most used measure in clinical practice to monitor cerebral ischaemia in patients undergoing carotid endarterectomy (CEA). Although end-tidal carbon dioxide (P CO ) is known as a factor that influences rSO , the relationship between P CO and rSO has not been quantitatively evaluated in patients with severe arteriosclerosis. This study aimed to evaluate the effect of P CO on rSO in patients undergoing CEA under general anaesthesia.
