Nebulized Morphine in Chest Trauma Patients: A Prospective Study

"We performed a first nebulization of 10 mg (1mL) of morphine diluted in 4 mL of normal saline using a nebulizer with an oxygen flow rate of 8 L / min. The quality of analgesia was assessed by VAS at rest and cough after 10 minutes. If ≤ 4, we concluded to a success. If VAS was still\> 4, a second nebulization was performed. After 20 minutes, if VAS still higher than 4 we performed a third nebulization. If pain level was ≤ 4, we concluded to a success. After 30 minutes, if VAS still\> 4, we concluded to a failure of morphine nebulization.~The patients were divided into two groups:~morphine (+) group: good response to morphine in nebulization morphine (-) group: failure of morphine in nebulization"
