Kokeellinen: neostigmine injection at the acupoints
|
On the basis of standard treatment, neostigmine was injected into the bilateral Zusanli (ST36) acupoints.
The patient was placed in the supine position with knees flexed.
Following routine local disinfection, a 5 mL disposable syringe was used to extract 0.5 mg of neostigmine for vertical subcutaneous needling and injection.
Upon needle withdrawal, the puncture site was compressed with sterile cotton swabs for hemostasis.
The identical procedure was applied to the contralateral Zusanli acupoint.
The intervention period is 1 day, with interventions administered twice daily (bid), 12 hours apart.
|
|
Active Comparator: intramuscular injection of normal saline
|
On the basis of standard treatment, normal saline was injected into bilateral Zusanli (ST36) acupoints.
The patient was placed in the supine position with knees flexed.
After routine local disinfection, a 5 mL disposable syringe was used for vertical needle insertion, and an equal volume of normal saline was injected subcutaneously into each acupoint.
Following injection, the needle was withdrawn, and the puncture site was compressed with sterile cotton swabs for hemostasis.The intervention period is 1 day, with interventions administered twice daily (bid), 12 hours apart.
|
|
Active Comparator: subcutaneous injection of neostigmine
|
On the basis of standard treatment, subcutaneous injection was performed at non-acupoint sites.
A 5 mL disposable syringe was used to aspirate 1 mg of neostigmine injection for single-site injection.
The injection site received routine disinfection beforehand.
Following the injection, the needle was withdrawn, and the puncture site was compressed with sterile cotton swabs for hemostasis.The intervention period is 1 day, with interventions administered twice daily (bid), 12 hours apart.

Remission rate of gastrointestinal symptoms within 24 hours
Aikaikkuna: within 24 hours after treatment
|
Gastrointestinal symptom relief is defined as meeting both recovery of spontaneous defecation (i.e., the first defecation after initial intervention with a defecation volume > 100 mL) and improvement in 24-hour gastric retention (24-hour gastric retention volume ≤ 500 mL).
