Effectiveness of supraglottic ventilation by transtracheal catheter for painless ERCP.

Purpose: This study aimed to investigate the effect of supraglottic ventilation via transtracheal catheter in painless endoscopic retrograde cholangiopancreatography (ERCP).

Methods: Sixty patients with painless ERCP who were treated in our hospital were enrolled as the study subjects and divided into a study group (n=30) and a control group (n=30) according to the method of ventilation during the operation. The control group received ventilation via modified laryngeal mask, while the study group received supraglottic ventilation through a transtracheal tube.

Influence of anesthetic induction of propofol combined with esketamine on perioperative stress and inflammatory responses and postoperative cognition of elderly surgical patients.

Objective: To analyze the influence of anesthetic induction of propofol combined with esketamine on perioperative stress and inflammatory responses and postoperative cognition in elderly surgical patients.

Methods: A total of 80 elderly surgical patients were randomly divided into a control group (n=40) and a study group (n=40). The control group received anesthetic induction with propofol combined with sufentanil, while the study group received anesthetic induction with propofol combined with esketamine.
