Postoperative discomfort of dental rehabilitation under general anesthesia

OBJECTIVE To find out postoperative discomfort in children undergoing dental rehabilitation under general anesthesia (DRGA). METHODS This study involved 78 (4 to 10 year-old) healthy patients who were scheduled for DRGA and were needed extensive dental treatment because of severe caries, and showed high dental fear and/or behavioral management problems. The children had to be fit for DRGA administration by fulfilling the American Society of Anesthesiologists physical status I or II and no associated mental health or communication problems. Data were collected by structured interview either face to face (immediately post operation) or using a telephone (post operation after discharge). One of the study's investigators recorded all data related to the immediate postoperative period during the child's stay in the post-anesthesia care unit (PACU). The questionnaire consisted of questions related to postoperative problems experienced by the patient in the period after their day-stay attendance. The questionnaire, consisting of questions regarding and generally related to the child's activities. In addition, pain was assessed using the face, legs, activity, cry, consolability (FLACC) scale. RESULTS The prevalence of postoperative problems was 46 out of 78 (59%). The mean FLACC score was 1.8 (SD=2.1). Some of the patients having more than one reported problem. Forty-one percent of the children showed nasal discomfort (P<0.01). Thirty-three percent and 43% of the children experienced throat or mouth discomfort. The most common experienced postoperative symptom after DRGA was bleeding. Nasal bleeding, however, was an uncommon complication and did not cause serious morbidity or mortality in children intubated nasotracheally. In addition, postoperative discomfort was related to number of the extractions. Children who had 4 or more extractions were more likely to experience pain. Findings associated with other bodily functions were assessed. Nausea and vomiting were reported in 20.5% of children. Twenty-six children (18%) had a fever. Thirty-nine (50.0%) parents reported that their children had problems eating. CONCLUSION Post-operative discomfort was more with 4 or more extraction done under DRGA and that nasal bleeding was noted a uncommon post-operative symptom.
