ABSTRACT

INTRODUCTION: Anti-N-methyl-D-aspartate receptor encephalitis is caused by auto-antibodies that target the N-methyl-D-aspartate receptor. Autonomic instability is a hallmark of the disease. The objective of this case series is to examine how anesthesia affects pediatric patients with this disease. METHODS: We performed a retrospective chart review of 28 records in 17 patients who underwent anesthesia. Our primary outcomes were hemodynamic changes during the perioperative period. Heart rate, systolic and diastolic blood pressures, respiratory rate, and oxygen saturation comprise our endpoints. A subgroup of patients, who underwent imaging with anesthesia, was then compared to controls. RESULTS: In anti-N-methyl-D-aspartate receptor encephalitis cases, there were significant percent changes from baseline in heart rate; median = -14.3%, 95% CI (-19.3, -9.0), p < .01 at 30 min and -15.7%, (-21.1, -9.8), p < .01 at 60 min; in systolic blood pressure, -19.4%, (-23.7, -14.8) at 30 min, p < .01, and -14.8%, (-19.7, -9.5) at 60 min, p < .01; in diastolic blood pressure, -41.9%, (-46.9, -36.3), p < .01 at 30 min, and -37.5%, (-43.4, -30.9), p < .01 at 60 min. When compared to controls, there were no significant differences between the two groups across time of anesthesia (baseline to 60 min) in heart rate (p = .24), systolic blood pressure (p = .30), and diastolic blood pressure (p = .11). No patients experienced hemodynamic lability under anesthesia. One patient, with severe symptoms, died within 24 h of anesthesia. CONCLUSION: Although pediatric patients with anti-N-methyl-D-aspartate receptor encephalitis experienced vital sign changes with anesthesia, they were not clinically significant and they behaved similarly to controls. Disease severity may be a risk factor for perioperative complications.

ABSTRACT

Lidocaine infusion is often used as part of a perioperative, multimodal pain management plan. We present its use to treat an 8-year-old child with devastating headaches. His symptoms stemmed from an inoperable supratentorial ependymoma that was causing thalamic bleeding and increased intracranial pressure. Many commonly used pain medications are associated with deleterious side effects such as bleeding and excessive sedation. These effects prevent lucidity for interactions, confound neurologic examination. A lidocaine infusion resulted in significant pain relief without these negative side effects. We discuss lidocaine infusion use and considerations for children suffering from intractable headaches.

ABSTRACT

INTRODUCTION: Propofol is an effective sedative for magnetic resonance imaging. Nevertheless, it may cause hemodynamic and respiratory complications in a dose dependent fashion. We investigated the role of low-dose dexmedetomidine (0.5 µg/kg) as an adjuvant to propofol sedation for children undergoing magnetic resonance imaging. We hypothesized that dexmedetomidine would decrease the propofol dose required, airway complications, and hemodynamic instability. METHODS: We performed a retrospective chart review of patients' age of 1 month to 20 years. Children were divided into 2 groups; group P received only propofol; group D + P received intravenous bolus of dexmedetomidine (0.5 µg/kg) and propofol. RESULTS: We reviewed 172 children in P and 129 in D + P (dexmedetomidine dose, median: 0.50 µg/kg (IQR: 0.45-0.62). An additional dexmedetomidine bolus was given to 17 children for sedation lasting longer than 2 hours. Total propofol dose (µg/kg/min) was significantly higher in group P than D + P; 215.0 (182.6-253.8) vs 147.6 (127.5-180.9); Median Diff = -67.8; 95%CI = -80.6, -54.9; P < .0001. There was no difference in recovery time (minutes); P: 28 (17-39) vs D + P: 27 (18-41); Median Diff = -1; 95%CI = -6.0, 4.0; P = .694. The need for airway support was significantly greater in P compared to D + P; 15/172 vs 3/129; OR = 0.25; 95%CI = 0.07 to 0.90; P = .02 (2-sample proportions test). Mean arterial pressure was significantly lower in P compared to D + P across time over 60 minutes after induction (coef = -0.06, 95%CI = -0.11, -0.02, P = .004). DISCUSSION & CONCLUSION: A low-dose bolus of dexmedetomidine (0.5 µg/kg) used as an adjuvant can decrease the propofol requirement for children undergoing sedation for magnetic resonance imaging. This may decrease the need for airway support and contribute to improved hemodynamic stability without prolonging recovery time.
