Introduction: This study was designed to compare the effectiveness of intravenous morphine with nebulized morphine in pain relief of patients referring to the emergency setting with traumatic musculoskeletal pain. Methods: This randomized, placebo-controlled and double-blind clinical study evaluated 160 patients 18 to 65 years of age with acute traumatic pain, who attended the emergency department during 2019. Subjects were assessed with Numerical Rating Scale based on inclusion and exclusion criteria and randomly divided into two groups. In one group, 80 patients received IV morphine (0.1 mg/kg+5 mL normal saline) plus an equivalent volume of IV placebo. In the second group, 80 patients received nebulized morphine (0.2 mg/kg+5 mL normal saline) plus nebulized placebo. Pain score was monitored in all patients with Numerical Rating Scale before and after intervention at baseline, 15, 30, 45, and 60-minute intervals. Patients’ vital signs and possible adverse events were evaluated in each observation time points. Finally, all participants were assessed for their satisfaction with pain management. Data were analyzed using repeated measure analysis for continuous variables and Binomial test for categorical variables Results: There was no significant difference between the demographic characteristics of patients in study groups. Pain relief between the two groups was similar during the observation (0, 15, 30, 45, 60 min) (P>0.05). There were no changes in vital signs between two groups, although the nebulized group had lower systolic blood pressure at the time-point of 15 minutes after the treatment initiation (P=0.03). Conclusion: Although Nebulized morphine has similar efficacy in comparison with IV route, nebulization might be considered as the clinically efficacious route of morphine administration with minimal side effects, providing optimal pain relief in patients.

Objective: The present study was conducted to investigate the effect of intradermal administration of sterile water compared to intravenous morphine on patients with renal colic. Methods: This double-blind, randomized clinical trial study was conducted in 2017 to compare the therapeutic effects of intradermal sterile water with those of intravenous morphine on patients with renal colic presenting to the emergency departments (ED) of Imam Khomeini and Golestan Hospitals in Ahvaz, Iran. The first group received 0.5 ml of intradermal sterile water, and the second group 0.1mg/kg of intravenous morphine plus 0.5 ml of intradermal sterile water in the most painful area or the center of the painful area in the flank. The pain severity was measured using a visual analogue scale (VAS), and the medication side-effects were recorded at the beginning of the study and minutes 15, 30,45 and 60. Result: A total of 94 patients were studied in two groups. The mean severity of pain was 2.97 ± 1.51 in the sterile water group and 2.34 ± 1.89 in the morphine group at minute 30 (P=0.042), 2.58 ± 1.43 in the sterile water group and 1 ± 1.23 in the morphine group at minute 45 (p<0.001), and 1.89 ± 1.7 in the sterile water group and 0.52 ± 0.79 in the morphine group at minute 60 (p<0.001). Conclusion: Morphine reduces pain faster and more effectively than intradermal sterile water; nevertheless, treatment with intradermal sterile water can be used as an appropriate surrogate or adjunct therapy for pain control, particularly in special patients or in case of medication scarcity.
