En randomiseret kontrolleret undersøgelse af inhalering af penehyclidin til forebyggelse af perioperative respiratoriske bivirkninger hos børn i risiko (PEPSI)

29. september 2026 opdateret af: Xiaoliang Gan, Sun Yat-sen University

Inhalering af penehyclidin for at forhindre perioperative respiratoriske hændelser hos børn i risiko, der gennemgår mindre elektiv kirurgi

This randomized controlled study is to evaluate the effectiveness of inhaling penehyclidine hydrochloride in reducing perioperative respiratory adverse events in children at risk undergoing minor elective surgery.

Studieoversigt

Detaljeret beskrivelse

Children with high risk factors of perioperative respiratory adverse events (PRAEs) remains a challenge for general anesthesia, inhalation of penehyclidine hydrochloride (PHC) has been showed to reduce postoperative pulmonary complications and enhance the recovery in high-risk surgical patients. Thus, prophylactic PHC inhalation might show promising benefits against PRAEs in pediatric anesthesia. This clinical study is designed to test the hypothesis that pediatric patients who exist at least 1 risk factor of PRAEs prophylactically to inhale PHC have a lower prevalence of PRAEs.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: The penehyclidine hydrochloride group

Inhaling penehyclidine hydrochloride (a dose of 0.05 mg/kg, diluted and mixed with normal saline to a total volume of 5 ml) for nebulization therapy within 30 min prior to surgery.

The penehyclidine hydrochloride will be diluted to a total volume of 5 mL with normal saline, added to the nebulizer cup for inhalation. Patients will be asked to inhale the entire volume of nebulized drugs within 30 min prior to surgery. The trial drugs will be administered using a jet nebulizer with compressed air flow. Each child will be intructed to begin the nebulization by using a face mask that covers the nose and mouth while the child is seated upright. Children will be encouraged to take deep and slow breaths, inhaling through the mouth and exhaling through the nose, to ensure the drugs effectively reaches the airway.

Placebo komparator: The normal saline group

Inhaling normal saline in a total volume of 5 ml for nebulization therapy within 30 min prior to surgery.

Foranstaltningsbeskrivelse
Tidsramme
The incidence of PRAEs
Tidsramme: From beginning of anesthesia induction until the completion of postoperative recovery in PACU (including the phases of anesthesia induction, anesthesia maintenance, postoperative emergency and postoperative recovery), assessed up to 24 hours.

PRAEs are subdivided into two types: major (bronchospasm and laryngospasm) and minor (severe coughing, breath holding, desaturation, upper airway obstruction, and stridor) events. The primary outcome is the incidence of PRAEs. Patients will be considered positive for respiratory adverse events if at least 1 of the above adverse events occurs.

From beginning of anesthesia induction until the completion of postoperative recovery in PACU (including the phases of anesthesia induction, anesthesia maintenance, postoperative emergency and postoperative recovery), assessed up to 24 hours.

Tidsramme: From beginning of anesthesia induction until the completion of postoperative recovery in PACU (including the phases of anesthesia induction, anesthesia maintenance, postoperative emergency and postoperative recovery), assessed up to 24 hours.

Laryngospasm will be scored according to its severity as follows: 1=none, 2=partial-reposition airway, 3=partial-continuous positive airway pressure (CPAP), 4=complete-muscle relaxant. Bronchospasm will be scored according to its severity as follows: 1=none, 2= expiration only, 3= expiration and inspiration, 4=difficult to ventilate, require treatment.
