Our goal was to evaluate how dental treatments under general anesthesia (GA) affect the quality of life by a prospective pair-matched design. Pediatric patients, who had received dental treatments under GA, were enrolled and were asked to complete the Early Childhood Oral Health Impact Scale (ECOHIS) before the treatment and 1 month after the treatment. To shield the observed impacts, a pair-ma...

BACKGROUND Effects of hypothermia on arterial baroreflex function during, and on its recovery after, general anesthesia were examined in humans. METHODS Twenty healthy volunteers were randomly assigned to a normothermic group (n = 10 each, active forced-air warming) or to a hypothermic group (no active warming) during anesthesia. Measurements of R-R intervals and systolic blood pressure were ...

Memory for words presented during general anesthesia was studied in two experiments. In Experiment 1, surgical patients (n = 80) undergoing elective procedures under general anesthesia were presented shortly before and during surgery with words via headphones. At the earliest convenient time after surgery (within 5 h) and 24 h later, memory was tested by asking patients to complete auditorily p...

BACKGROUND There is a considerable rate of fertility failure and this causes a great burden of untoward effects for patients. Usually a considerable number of these patients undergo anesthesia for their treatment. OBJECTIVES This study was designed to compare the effects of general and spinal anesthesia on these patients. PATIENTS AND METHODS In a randomized clinical trial, after taking inf...

Although generally safe and effective, severe perioperative complications, including cardiac arrest, may occur during general anesthesia in infants. With the emergence of evidence that specific anesthetic agents may affect future neurocognitive outcomes, there has been an increased focus on alternatives to general anesthesia, including spinal anesthesia. We present a case of cardiac arrest duri...

The aim of this article is to give an overview of recent developments in the field of general anesthesia monitoring. We measure different physiological signals related to the functioning of several nervous systems. Using statistical or signal processing methods, monitors are derived and correlated to the dosage of anesthetic agents and to the status of the patient. Comparisons among existing mo...

THEORIES of general anesthetic mechanism have evolved from the unitary hypothesis of Claude Bernard in the nineteenth century to our current understanding of the multiple receptors and neural systems affected by anesthetic agents. As the scientific study of general anesthesia has progressed, it has become clear that early unifying theories of anesthetic mechanism, although elegant, do not accou...

Regional anesthetic techniques in children have become more popular in the past decade. This is in part because of recent research indicating biobehavioral changes associated with untreated pain in children.2, 86 Most regional techniques in children are performed under heavy sedation or general anesthesia. Concerns regarding safety and the medicolegal liability of performing regional blocks und...
