BackgroundPremedication is the most common way to minimize distress in children entering the operating room and to facilitate the smooth induction of anesthesia and is accomplished using various sedative drugs before the children are being transferred to the operating room. The aim of this study was to compare the effect of oral dexmedetomidine (DEX) and oral midazolam (MID) on preoperative cooperation and emergence delirium (ED) among children who underwent dental procedures at our hospital between 2016 and 2017.Patients and methodsThe medical records of 52 children, who were American Society of Anesthesiologists I, aged between 3 and 7 years, and who underwent full-mouth dental rehabilitation under general anesthesia (GA), were evaluated. Twenty-six patients were given 2 µg/kg of DEX, while another 26 patients were given 0.5 mg/kg of MID in apple juice as premedication agents. The patients’ scores on the Ramsay Sedation Scale (RSS), Parental Separation Anxiety Scale (PSAS), Mask Acceptance Scale, Pediatric Anesthesia Emergence Delirium Scale (PAEDS), and hemodynamic parameters were recorded from patients’ files. The level of sedation of children had been observed just before premedication and at 15, 30, and 45 min after premedication. The data were analyzed using a chi-square test, Fisher’s exact test, Student’s t-test, and analysis of variance in SPSS.ResultsThe Mask Acceptance Scale and PSAS scores and RSS scores at 15, 30, and 45 min after premedication were not statistically different (p>0.05) in both groups, whereas the PAEDS scores were significantly lower in the DEX group (p<0.05).ConclusionOral DEX provided satisfactory sedation levels, ease of parental separation, and mask acceptance in children in a manner similar to MID. Moreover, children premedicated with DEX experienced lesser ED than those premedicated with MID.

BackgroundPediatric dental procedures are performed under anesthesia because children may be uncooperative in the dental clinic due to their young age. Emergence delirium (ED), which involves a variety of behavioral disturbances that are frequently observed in children following emergence from general anesthesia, remains an unclear phenomenon. The aim of this randomized controlled trial is to compare the incidence of ED in children who underwent full mouth dental rehabilitation under either sevoflurane (SEVO) anesthesia or propofol-based total intravenous anesthesia (TIVA).Patients and methodsOne hundred and twenty children with American Society of Anesthesiologists status I–II, aged ≥3 and ≤6 years, undergoing dental rehabilitation were assigned to receive either TIVA or SEVO. ED and postoperative pain were evaluated by a blinded investigator using the Pediatric Anesthesia Emergence Delirium scale and the Face, Legs, Activity, Cry, Consolability scale every 5 min. The recovery time, satisfaction levels of parents or guardians, extubation time, duration of the operation, and type of dental procedure were also recorded.ResultsData of 116 subjects were analyzed. The incidence of ED was higher after SEVO than after TIVA (65.5 vs 3.4%, P=0.00). Greater postoperative pain was observed in the SEVO group (median 3 vs 1, P=0.000). A statistically significant, moderate correlation (rs=0.46, P<0.0001) was found between the Face, Legs, Activity, Cry, Consolability and Pediatric Anesthesia Emergence Delirium scores. A higher parental satisfaction level was observed in the TIVA group.ConclusionA lower incidence of ED and a higher parental satisfaction level were observed after TIVA. Moreover, TIVA resulted in a more comfortable postoperative period due to reduced postoperative pain, and the extubation time and recovery time were not increased.

Introduction The aim of this study was to detect the effect of 1 μg/kg of oral dexmedetomidine (DEX) as premedication among children undergoing dental procedures. Materials and Methods The study involved 100 children between 2 and 6 years of age, ASA I, who underwent full-mouth dental rehabilitation. The DEX group (n = 50) received 1 μg/kg DEX in apple juice, and the control group (n = 50) received only apple juice. The patients' scores on the Ramsay Sedation Scale (RSS), parental separation anxiety scale, mask acceptance scale, and pediatric anesthesia emergence delirium scale (PAEDS) and hemodynamic parameters were recorded. The data were analyzed using chi-square test, Fisher's exact test, Student's t-test, and analysis of variance in SPSS. Results RSS scores were significantly higher in the DEX group than group C at 15, 30, and 45 min (p < 0.05). More children (68% easy separation, 74% satisfactory mask acceptance) in the DEX group showed satisfactory ease of parental separation and mask acceptance behavior (p < 0.05). There was no significant difference in the PAEDS scores and mean hemodynamic parameters of both groups. Conclusions Oral DEX administered at 1 μg/kg provided satisfactory sedation levels, ease of parental separation, and mask acceptance in children but was not effective in preventing emergence delirium. The trial was registered (Protocol Registration Receipt NCT03174678) at clinicaltrials.gov.

The risk limit for PONV was determined to be ≥5.5 years for children who underwent dental procedures under general anesthesia. Postoperative pain and rescue analgesia constituted risks for PONV.
