The study sample was 60 and divided into two equal groups. All data entered in MS-Excel Sheet and Wilcoxon signed-rank test were done for nonparametric data and one-way ANOVA for the parametric data. The normal distribution of the study sample was tested by the Shapiro - Wilk test.</p><p><strong>Results: </strong>The fasciculations in the test group were much less than in the control group with <i>P</i> < 0.00001. The results for the incidence of myalgia in the two groups were as follows: <i>P</i> value at 24 h was 0.00018 and at 48 h was 0.0028, respectively. Creatine kinase levels at preoperative and 24 h postoperative periods were 49.47 ± 7.24 in Group D, 53.30 ± 7.98 in Group B and 87.38 ± 15.16 in Group D, and 188.41 ± 33.27 in Group B, respectively.</p><p><strong>Conclusion: </strong>Succinylcholine-induced myalgia has a complex pathophysiology. However, the preemptive use of diclofenac in combination with precurarization can alleviate the incidence and severity of succinylcholine-induced myalgia. Therefore, its use may be considered in routine cases for induction of anesthesia for facilitating laryngoscopy and endotracheal intubation.</p>","PeriodicalId":7798,"journal":{"name":"Anesthesia, Essays and Researches","volume":"16 1","pages":"89-93"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9558659/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33544728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
