BACKGROUND: Succinylcholine has a fast onset, short duration of action, and is considered the choice for rapid sequence intubation. However, it produces muscle stiffness and postoperative myalgia (POM) as adverse effects. We hypothesized that the antioxidant selenium might affect POM incidence and severity.  OBJECTIVES: The study aimed to investigate the antioxidant effect of selenium (against free radicals’ release) in minimizing the frequency of succinylcholine-related POM, measured by the 4-point myalgia score. The severity of fasciculations and the postoperative analgesic profile were recorded. The correlation between fasciculations and POM was also observed.  STUDY DESIGN: A prospective randomized controlled double-blind clinical study.  SETTING: Assiut University Hospitals.  METHODS: The current study included 80 adult patients scheduled for sinuscopies and randomly assigned into 2 equal groups. Two hours before the induction of general anesthesia, patients in the control group received oral placebo tablets, while patients in the selenium group received oral selenium 200 µg. The primary outcome of this trial was the POM score at 24 hours. Secondary outcomes included the intensity of fasciculations, Numeric Rating Scale (NRS), rescue analgesic consumption, and adverse effects of the studied drugs.  RESULTS: Myalgia scores were significantly decreased after selenium administration throughout the follow-up period (P = 0.023). No significant difference was reported regarding the incidence or degree of fasciculations (P = 0.511). A mild correlation was noticed between fasciculations and POM with r = 0.176 and P &lt; 0.061. The NRS values were significant between groups at 6 hours after the procedure. There were significant differences (P &lt; 0.05) regarding postoperative supplement analgesia, time to the first rescue analgesia, and the mean total number of analgesic claims. Significant differences were recorded for potassium levels only 30 minutes and creatine kinase levels at 6 and 24 hours postoperatively.  LIMITATIONS: This study was applied on a single surgical category and other types of surgical procedures may have an effect on outcomes. Additional larger sample size studies and various doses of selenium may help to validate our results. Selenium is quite a significant element of the enzymatic antioxidant process through glutathione peroxidase. We did not measure the glutathione peroxidase level in blood.  CONCLUSIONS: Oral selenium effectively reduced the succinylcholine-induced postoperative myalgia. It prolonged the time to first required analgesia and decreased the analgesic consumption throughout the whole study period without affecting the hemodynamics or any serious adverse effects.
