Registration Number
NCT06689124
Lead Sponsor
Bangkok Metropolitan Administration Medical College and Vajira Hospital
Brief Summary

This clinical trial compares three different nebulized fentanyl dosages for older persons experiencing severe musculoskeletal pain at the emergency department.

The main objective is:

Does the effectiveness of nebulized fentanyl at dosages of 2 mcg/kg, 3 mcg/kg, and 4 mcg/kg at 30 minutes differ in older patients who report to the emergency room with pain from musculoskeletal injuries?

Secondary outcome are:

1. Incidence of adverse effects after drug administration at minutes 0, 15, 30, 45, 60, 75, 90, 105, 120

2. Incidence of receiving other pain relief treatments (rescue therapy) in minutes 30, 45, 60, 75, 90, 105, 120 Participants will receive an explanation of the study and possible side effects, which may take approximately 5-10 minutes, without affecting the primary treatment of the patients. Consent will be obtained in this study, along with signing or fingerprinting as evidence in the consent form.

Detailed Description

Participants will receive nebulized fentanyl for pain reduction at the pre-determined randomized dose, then researchers will follow up assessments of pain levels, vital signs, and any side effects at various intervals.

GroupInterventionDescription
Nebulized fentanyl 2 mcg/kgNebulized fentanylThe researcher prepared fentanyl (the researcher informed the in-charge nurse to open the medicine cabinet and double-checked the dosage with the in-charge nurse). The dosage was 2 micrograms per kilogram of body weight (calculated based on the patient's actual weight in kilograms). The medication was contained in a nebulizer. It was then mixed with normal saline (0.9% normal saline) to a total volume of 5 milliliters and administered via nebulization.
Nebulized fentanyl 3 mcg/kgNebulized fentanylThe researcher prepared fentanyl (the researcher informed the in-charge nurse to open the medicine cabinet and double-checked the dosage with the in-charge nurse). The dosage was 3 micrograms per kilogram of body weight (calculated based on the patient's actual weight in kilograms). The medication was contained in a nebulizer. It was then mixed with normal saline (0.9% normal saline) to a total volume of 5 milliliters and administered via nebulization.
Nebulized fentanyl 4 mcg/kgNebulized fentanylThe researcher prepared fentanyl (the researcher informed the in-charge nurse to open the medicine cabinet and double-checked the dosage with the in-charge nurse). The dosage was 4 micrograms per kilogram of body weight (calculated based on the patient's actual weight in kilograms). The medication was contained in a nebulizer. It was then mixed with normal saline (0.9% normal saline) to a total volume of 5 milliliters and administered via nebulization.
Primary Outcome Measures
NameTimeMethod
Efficacy in pain reduction following nebulized fentanyl administration at different dosages.30 Minutes

Efficacy in pain reduction following nebulized fentanyl administration at dosages of 2 mcg/kg, 3 mcg/kg, and 4 mcg/kg in elderly patients presenting to the emergency department with musculoskeletal pain, using verbal numerical rating scale (VNRS) VNRS score ranges from 0 to 10, with a higher score indicating more severe pain. Ten indicates the worst pain, and zero indicates no pain.
