RESUMO
INTRODUCTION: The goal of this study was to identify the etiology of events and demographics of patients that experience complications requiring activation of the Rapid Response Team (RRT) during the first 24 h following anesthetic care. METHODS: We performed a retrospective review of the Quality Improvement database from the Department of Anesthesiology & Pain Medicine at Nationwide Children's Hospital. The database was searched to identify those patients who had a RRT evaluation activated within 24 h of receiving anesthesia or procedural sedation. These patients' charts were reviewed to obtain demographic information, etiology of the RRT call, and outcomes. RESULTS: The study cohort included 106 RRT calls that were made over a 3-year period. Six patients were excluded from analysis due to incomplete datasets. One hundred patients remained for analysis including 60 males and 40 females. Patients ranged in age from 0.08 to 31.21 years (7.8 ± 7.7 years, median 5.3 years). Seventy-one patients were American Society of Anesthesiologists' (ASA) status 3 or 4 and 29 patients were ASA status 1 or 2. Five calls were made for patients who had undergone procedural sedation while the other 95 were on patients who received general anesthesia. The average time to the RRT call after the end of anesthetic care was 11.4 ± 6.6 h. Respiratory concern was the most common reason for RRT initiation, accounting for 71 of the 100 calls. Forty-nine patients had a recent respiratory illness, chronic respiratory-related disease, or history of preterm birth. Fifty patients (50%) were transferred to a higher level of care following the RRT consult. There was no significant difference between age, gender, ASA status, or etiology of the event for patients transferred vs. those who were not. A significant difference was noted in the Pediatric Early Warning Score of patients transferred to a higher level of care in comparison to patients who remained on the floor (4 ± 2 vs. 3 ± 2, P = 0.0097). CONCLUSION: RRT calls were most common for respiratory concerns. High ASA status, general anesthesia administration, and the presence of acute or chronic conditions prior to anesthetic administration predispose a patient to perioperative complications resulting in the need for an RRT call.

BACKGROUND: Functional magnetic resonance imaging (fMRI) has been used to evaluate the long-term consequences of early exposure to neurotoxic agents. fMRI shows that different patterns of brain activation occur in ethanol-exposed subjects performing a go/no-go response inhibition task. Pharmacologically, ethanol and general anesthetics have similar receptor-level activity in the brain. This study utilizes fMRI to examine brain activation patterns in children exposed to general anesthesia and surgery during early brain development. METHODS: After obtaining Nationwide Children's Hospital IRB approval, a surgical database was utilized to identify children aged 10-17 years with a history of at least 1 h of exposure to general anesthetics and surgery when they were between 0 and 24 months of age. Age- and gender-matched children without anesthesia exposure were recruited as a control group. All subjects were scanned while being presented with a go/no-go response inhibition task. Reaction time and accuracy data were acquired, and the blood-oxygen-level-dependent (BOLD) fMRI signal was measured as a biomarker for regional neuronal activity. RESULTS: There were no differences in terms of performance accuracy and response time. The analysis did not reveal any significant activation differences in the primary region of interest (prefrontal cortex and caudate nucleus); however, activation differences were seen in other structures, including the cerebellum, cingulate gyrus, and paracentral lobule. CONCLUSIONS: Early anesthetic exposure and surgery did not affect accuracy, response time, or activation patterns in the primary region of interest during performance of the task. Intergroup differences in activation patterns in other areas of the brain were observed, and the significance of these findings is unknown. fMRI appears to be a useful tool in evaluating the long-term effects of early exposure to general anesthesia.

OBJECTIVES: We compared three primary outcomes of pausing the magnetic resonance imaging (MRI) scan, emergence quality and respiratory complications. AIM: To measure and compare the quality between sevoflurane and propofol in children undergoing MRI scans. BACKGROUND: No randomized controlled trial exists comparing the quality between sevoflurane and propofol for MRI. METHODS/MATERIALS: Two hundred unpremedicated children (18 months to 7 years) scheduled for brain MRI scans were recruited. After induction with sevoflurane, children were randomized to receive sevoflurane [general anesthesia with sevoflurane (GAS)] via laryngeal mask airway (LMA) or propofol [general anesthesia with propofol (GAP)] bolus and infusion for their scan. The three primary outcomes of pausing the MRI scan (P), agitation (A), and respiratory complications (R) were compared. Timeliness of care was also measured. RESULTS: No MRI scan pauses were found in 92% and 80% in the GAS and GAP groups. The median and interquartile A scores were 3 (0, 7) in GAS and 0 (0, 4) in GAP groups respectively. There was no difference in respiratory complications between GAS and GAP (P = 0.62). The median and interquartile postanesthesia care unit (PACU) times were 25 (18, 34) for GAS and 31 (25, 44) for GAP (P = 0.0001). The median and interquartile total times were 78 (69, 90) for GAS and 88 (78, 100) for GAP (P = 0.0002). CONCLUSION: Our study compared the three primary outcomes of pausing, agitation, and respiratory complications between the two groups, and we found no difference in respiratory complications. However, the GAP group had more pausing and less agitation than the GAS group.
