Meta Analysis Comparative StudyComparison between hemodynamic effects of remimazolam and propofol during general anesthesia: a systematic review and meta-analysis.
The need for safe anesthetic agents with minimal side effects has led to the development of remimazolam, a new benzodiazepine designed to be an alternative to the commonly used drug propofol, which has significant hemodynamic effects. This study aims to compare the hemodynamic effects of remimazolam with propofol during general anesthesia. ⋯ This study provides evidence that remimazolam induces fewer cardiorespiratory depressant effects and has a more favorable side effect profile compared to propofol during general anaesthesia.

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.

Investigating the effect of magnesium sulfate (MS) on emergence agitation (EA) in adult surgical patients following general anesthesia (GA). ⋯ Limited available evidence suggests that MS was associated with a lower incidence of EA. Nevertheless, further high-quality studies are warranted to strengthen and validate the effect of MS in preventing EA in adult surgical patients.

Three linked clinical observations prompted our current understanding of perioperative heat balance. The first was the extraordinarily rapid decrease in core temperature after induction of general anesthesia which led to an understanding of redistribution hypothermia. The second was the linear reduction in core temperature during the subsequent 2-3 h which led to an understanding of anesthetic effects on metabolic heat production and factors that influence cutaneous heat loss. And the third was the observation that core temperature reaches a plateau at about 34.5 °C which led to the understanding that thermoregulatory vasoconstriction re-emerges when patients become sufficiently hypothermic, and that arteri-venous shunt constriction constrains metabolic heat to the core thermal compartment.
