Randomized Controlled Trial
Electroencephalographic features of elderly patients during anesthesia induction with remimazolam: a sub-study of a randomized controlled trial.
Although remimazolam is used as a general anesthetic in elderly patients due to its hemodynamic stability, the electroencephalogram characteristics of remimazolam are not well known. The purpose of this study was to identify the electroencephalographic features of remimazolam-induced unconsciousness in elderly patients and compare them with propofol. ⋯ Both regimens showed a greater decrease in feedback connectivity compared to a decrease in feedforward connectivity after loss of consciousness, leading to a disruption of asymmetry between the frontoparietal connectivity.

Randomized Controlled TrialINJEX50 could improve the success rate of local anesthesia for arterial cannulation in the pediatric intensive care unit: A randomized, double-blind, single-center study.
Quick arterial cannulation is required in pediatric emergency situation, which require effective local anesthesia to avoid withdrawal movement. However, pediatric local anesthesia could be difficult because of withdrawal movement. Jet injectors, which are needleless and provide local anesthesia quickly, could be helpful for pediatric local anesthesia during arterial cannulation. ⋯ Seventy patients were randomly assigned to groups C and I. The local anesthesia success rate in group I (30/35 [86%]) was significantly higher than that in group C (15/35 [43%], odds ratio, 8.00; 95% confidence interval, 2.51-25.5; p = .0005). In conclusion, INJEX50 could improve success rate of local anesthesia for arterial cannulation in pediatric intensive care unit compared with 26-gauge needle.

ReviewKeeping patients in the dark: perioperative anesthetic considerations for patients receiving 5-aminolevulinic acid for glioma resection.
5-Aminolevulinic acid hydrochloride (5-ALA), available under the trade name Gleolan, is an orally administered fluorophore drug used to enhance visual differentiation of cancerous tissue from healthy tissue, primarily during surgical resection of high-grade gliomas. Although given preoperatively, 5-ALA has important implications for anesthetic care throughout the perioperative period. This article reviews pharmacology, safety concerns, and perioperative considerations for patients who receive oral 5-ALA. ⋯ Mitigating the possible side effects of 5-ALA requires an understanding of its basic mechanism as well as focused perioperative planning and communication. Administration of this medication may result in nausea, vomiting, photosensitivity, increase in serum concentration of liver enzymes, and hypotension. Patients who receive 5-ALA must be protected from prolonged light exposure during the first 48 h after consumption and administration of other photosensitizing agents should be avoided (Supplemental Video File/Video abstract).

Although effects of general anesthesia on neuronal activity in the human neonatal brain are incompletely understood, electroencephalography provides some insight and may identify age-dependent differences. ⋯ Although evidence gaps were identified, both increasing sevoflurane concentration and decreasing temperature are associated with increasing discontinuity.

Randomized Controlled Trial Comparative StudyComparison of automated and manual control methods in minimal flow anesthesia.
New-generation anesthesia machines administer inhalation anesthetics and automatically control the fresh gas flow (FGF) rate. This study compared the administration of minimal flow anesthesia (MFA) using the automatically controlled anesthesia (ACA) module of the Mindray A9 (Shenzhen, China) anesthesia machine versus manual control by an anesthesiologist. ⋯ The ACA mode was more advantageous than the MCA mode, reaching target AA concentrations faster and requiring fewer adjustments to achieve a constant depth of anesthesia.
