We investigated changes in plasma glial fibrillary acidic protein concentration during sevoflurane anesthesia induction in children < 3 years old and determined the effect of co-administering dexmedetomidine. This preliminary randomized trial included 60 pediatric patients who received sevoflurane anesthesia for >3 h. Patients were assigned to dexmedetomidine or control groups at a 1:1 ratio. The primary outcome was changes in plasma glial fibrillary acidic protein concentration of dexmedetomidine and control groups over time. Fifty-five patients were included in the final analysis. The median (interquartile range (IQR)) of the plasma glial fibrillary acidic protein level was 387.7 (298.9–510.8) pg·mL−1 immediately after anesthetic induction, 302.6 (250.9–412.5) pg·mL−1 at 30 min, and 321.9 (233.8–576.2) pg·mL−1 at 180 min after the first sample. These values did not change over time (p = 0.759). However, plasma glial fibrillary acidic protein increased after 180 min of infusion of dexmedetomidine compared with values at 30 min infusion (p = 0.04, mean difference and 95% confidence interval of 221.6 and 2.2 to 441.0 pg·mL−1). In conclusion, three hours of sevoflurane anesthesia in pediatric patients < 3 years old did not provoke neuronal injury assessed by the plasma biomarker. Further studies regarding the effect of prolonged dexmedetomidine infusion on anesthetic neuronal injury are required.

OBJECTIVES: Emergence agitation (EA) is a common and troublesome problem in pediatric patients recovering from general anesthesia. The incidence of EA is reportedly higher after general anesthesia maintained with sevoflurane, a popular inhalational anesthetic agent for pediatric patients. We conducted this prospective, randomized, double-blind study to test the effect of an intravenous ultra-short–acting barbiturate, thiamylal, administered during induction of general anesthesia on the incidence and severity of EA in pediatric patients recovering from Sevoflurane anesthesia. METHODS: Fifty-four pediatric patients (1 to 6 years of age) undergoing subumbilical surgeries were randomized into 2 groups. Patients received either intravenous thiamylal 5mg/kg (Group T) or inhalational Sevoflurane 5% (Group S) as an anesthetic induction agent. Following induction, general anesthesia was maintained with Sevoflurane and nitrous oxide (N2O) in both groups. To control the intra- and post-operative pain, caudal block or ilioinguinal/iliohypogastric block was performed. The incidence and severity of EA were evaluated by using the Modified Objective Pain Scale (MOPS: 0 to 6) at 15 and 30 min after arrival in the post-anesthesia care unit (PACU). RESULTS: Fifteen minutes after arrival in the PACU, the incidence of EA in Group T (28%) was significantly lower than in Group S (64%; p = 0.023) and the MOPS in Group T (median 0, range 0 to 6) was significantly lower than in Group S (median 4, range 0 to 6; p = 0.005). The interval from discontinuation of Sevoflurane to emergence from anesthesia was not significantly different between the 2 groups. CONCLUSIONS: Thiamylal induction reduced the incidence and severity of EA in pediatric patients immediately after Sevoflurane anesthesia.

Abstract Background: Inhalational anesthetic effects on upper airway muscle activity in children are largely unknown. The authors tested the hypothesis that phasic inspiratory genioglossus and palatoglossus activity increases during recovery from sevoflurane anesthesia in a dose-dependent manner in children. Methods: Sixteen children, aged 2.0 to 6.9 yr, scheduled for elective urological surgery were studied. Electromyogram recordings were acquired using intramuscular needle electrodes during spontaneous ventilation. After a 15-min period of equilibration, electromyogram activity was recorded over 30 s at each of three end-tidal concentrations, 1.5, 1.0, and 0.5 minimum alveolar concentration (MAC), administered in sequence. Results: Phasic genioglossus activity was noted in four children at 1.5 MAC, five at 1.0 MAC, and six children at 0.5 MAC sevoflurane. Phasic palatoglossus activity was noted in 4 children at 1.5 MAC, 6 at 1.0 MAC, and 10 children at 0.5 MAC sevoflurane. Both the proportion of children exhibiting phasic activity, and the magnitude of phasic activity increased during recovery from anesthesia. For the genioglossus, decreasing the depth of sevoflurane anesthesia from 1.5 to 1.0 MAC increased phasic activity by approximately 35% and a further decrease to 0.5 MAC more than doubled activity (median [range] at 1.5 and 0.5 MAC: 2.7 μV [0 to 4.0 μV] and 8.6 μV [3.2 to 17.6], respectively; P = 0.029). A similar dose-related increase was recorded at the palatoglossus (P = 0.0002). Conclusions: Genioglossus and palatoglossus activity increases during recovery from sevoflurane anesthesia in a dose-dependent manner over the clinical range of sevoflurane concentrations in children.

OBJECTIVES : To study the role of dexmedetomidine on emergence agitation and its effect on extubation in paediatric adenotonsillectomy. Our study involves the assessment of postoperative pain by Objective Pain Scale and need for rescue analgesia and other untoward events in PACU. The study also included the comparision of post operative recovery time by Modified Aldrete Recovery Score using dexmedetomidine and normal saline in adenotonsillectomy for pediatric patients. METHODS : After induction of general anesthesia patient was put on controlled ventilation and maintained on sevoflurane 1.5-2% with 66% O2 and 33% N2O. At the end of surgery patients received either dexmedetomidine or normal saline over a period of 5 minutes, sevoflurane and nitrous oxide were discontinued, and residual muscle relaxation was reversed. Tracheal extubation time (time from anesthetic gas discontinue to tracheal extubation) and emergence time (time from anesthetic gas discontinue to eye opening on command) were recorded. Incidence of untoward airway events after extubation were also noted. The subject’s postoperative behaviour was assessed using Pediatric Anesthesia Emergence Delirium (PAED). In PACU, the intensity of pain was assessed by using an observational pain score (OPS). Any untoward events were noted and patient was shifted as per modified PACU score. RESULTS: In this randomized comparative study, single dose of dexmedetomidine (0.5mcg/kg) was found to be associated with a statistically significant decrease in the incidence of emergence agitation along with smooth extubation in pediatric patients undergoing adenotonsillectomy with sevoflurane anesthesia. In addition, lower incidence of post-operative nausea and vomiting, lower pain score and shorter duration of stay in post-anesthesia care unit were observed. Although it was seen that the extubation was prolonged in the dexmedetomidine group in comparison to the placebo. CONCLUSION: Dexmedetomidine reduces emergence agitation and provides smooth extubation in pediatric adenotonsillectomy patients on sevoflurane anesthesia.

INTRODUCTION: Oculocardiac reflex (OCR) activation is common during the strabismus surgery. As a result of the OCR, sinus bradycardia, atrioventricular block, ventricular fibrillation and even asystole may occur. Pediatric patients are also more vulnerable to harmful effects of this reflex. The aim of this study was to determine the possible risk factors affecting the incidence of OCR in pediatric patients undergoing strabismus surgery. METHODS: The medical records of the pediatric patients who underwent strabismus surgery between January 2015 and September 2018 were retrospectively reviewed. Operations performed by only one surgeon. OCR was defined as a more than 20% reduction in HR induced by the extraocular muscle (EOM) manipulation. Demographic data, duration of surgery, history of any previous strabismus surgery and possible development of OCR, anesthesia management, neuromuscular blocker and anesthetic drugs used for the anesthesia induction and maintenance as well as the airway management, the number of operated eyes, and also the muscle types of the patients were all recorded. Risk factors for OCR were evaluated by logistic regression analysis. RESULTS: Out of 92 pediatric patients who were initially evaluated, six were excluded from the study because their files were missing. A total of 86 patients were included in the study. During surgery, OCR occurred in 29 (33.7%) patients. The absence of administering benzodiazepine for premedication (p=0.03) and neuromuscular blocker after induction (p=0.046) in pediatric patients are specified as independent risk factors. We found that the use of a neuromuscular blocker and benzodiazepine in premedication reduced the risk of OCR by 3.64 and 3.11 times, respectively. DISCUSSION AND CONCLUSION: The incidence of OCR may decrease with preventive measures such as neuromuscular blocker application, premedication with benzodiazepine in strabismus surgeries.
