Comparison of patients with and without intellectual disability under general anesthesia: A retrospective study

Background and Purpose: We analyzed and retrospectively compared patients with and without intellectual disability (ID) who underwent oral surgery under general anesthesia at Istanbul University, Faculty of Dentistry, Department of General Anesthesia, between October 2012 and June 2013 with regard to the following categories: Demographic features, American Society of Anesthesiologists (ASA) classification, Mallampati score, type of anesthetic drug used during the operation, type of intubation used, any difficulties with tracheal intubation, presence of systemic diseases, and recovery times after ending general anesthesia. Materials and Methods: A total of 348 patients were selected from the Department of Maxillofacial Surgery and the Department of Pedodontics who underwent surgery with general anesthesia. Medical histories of all patients were taken, and their electrocardiography, chest X-rays, complete blood count, and blood clotting tests were checked during a preoperative assessment. Mallampati evaluations were also performed. Patients were grouped into ASA I, II, or III according to the ASA classification and were treated under general anesthesia. Results: There was no significant difference between normal and intellectually disabled patients in terms of gender, Mallampati scores, intubation difficulties, mean anesthetic period, time to discharge, or postoperative nausea and vomiting. Epilepsy and genetic diseases in intellectually disabled patients were significantly more common than in non-ID (NID) patients. However, the frequency of diabetes and chronic obstructive pulmonary disease in NID patients was significantly higher than in the intellectually disabled patients. Conclusion: Dental treatment of intellectually disabled patients under general anesthesia can be performed just as safely as that with NID patients.
