Introduction       High dose of ketamine is administered in general anesthesia and low dose is used to induce analgesia. Intravenous ketamine is usually used for hernia repair as well as cutaneous interventions in general surgery, for dilatation and curettage in gynecology, and hydrocele repair in urology. Materials and Methods       This study reports the outcomes of 49 patients who had been operated by volunteering surgical team of Doctors Worldwide in Sierra Leone during 10th to 16th of March 2014. Demographic features of all patients and surgical methods were recorded. All patients were operated on under ketamine anesthesia. Results       Five female and 44 male patients with mean age of 36.8+17.8 were operated. One patient had umbilical, 1 had epigastric, and 35 had giant inguinal hernias. Umbilical and epigastric hernias underwent primary repair. Inguinal hernias were right sided in 19, and left sided in 16 patients. Twenty-eight patients had indirect hernias, while 6 had direct and 1 had bilateral hernias. None of the patients appeared with either obstruction or strangulation. Four patients in pediatric age with hernia underwent high ligation. In adult age group, 28 patients were operated by wall darn repair, and 3 had Bassini repair. Four patients had been diagnosed with right sided, and 4 left sided giant hydroceles all of which underwent Winkelmann procedure. One patient had orchiectomy for a right sided testicular mass; 1 had resection of an inguinal tumor; 1 excision of lipoma in the neck, and 1 excision of a solid mass in the left labium majus. None of the patients had complications related to anesthesia. Conclusion       Safe and effective sedation by low dose intravenous administration of ketamine and midazolam is beneficial in surgical procedures, especially in field conditions where general anesthesia is not applicable.
