A Phase 1 interventional study of full dose of Neostigmine and half dose of Neostigmine in Diaphragm Ultrasound, sponsored by Aswan University Hospital. Not yet recruiting. Open to participants aged 18 Years to 75 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-01-22.

The goal of this Randomized Clinical Trial is to compare the postoperative diaphragmatic excursion between patients receiving half-dose neostigmine (0.04 mg/kg) and those receiving full-dose neostigmine (0.08 mg/kg) for neuromuscular blockade reversal.
The main questions it aims to answer are:
Participants will:
Fifty patients from both genders scheduled for elective laparoscopic cholecystectomy were enrolled in this study to compare diaphragmatic assessment parameters.
Enrolled participants were randomly assigned to group A (patient receiving full dose of Neostigmine (0.08 mg/kg) plus Atropine (20 mic/kg)) or group B (patient receiving half dose of Neostigmine (0.04 mg/kg) plus Atropine (20 mic/kg)).
This is a prospective study that will be conducted at Aswan University Hospital.
Eligible participants will be adult patients (age ≥ 18 years) scheduled for elective laparoscopic cholecystectomy, with American Society of Anesthesiologists (ASA) physical status I or II, and a body mass index (BMI) \< 35 kg/m². Patients with pre-existing diaphragmatic or respiratory disorders, ASA physical status III or IV, BMI > 35 kg/m², chronic opioid use or abuse, pregnancy, or breastfeeding will be excluded.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
