The Utility of BIS™ Monitoring in Anesthesia for Elderly Patients.

Aging leads to anatomic and physiologic changes in the brain, making it more sensitive to the depressant effects of anesthetic medications and increasing the risk of postoperative neurocognitive complications such as postoperative delirium and postoperative cognitive dysfunction. This article explores the implications of anesthesia on elderly patients' brain health, emphasizing the heightened risk of postoperative neurocognitive disorders, and describes the BIS™ Monitoring System as a neuromonitoring tool for anesthesia professionals to assess the depth of anesthesia. The integration of the BIS Monitoring System into clinical practice can contribute to a more tailored and patient-centered approach to anesthesia management, ultimately improving perioperative outcomes and safety.

Calcinosis Universalis: Cause for a Hard Airway.

Calcinosis universalis is a rare subtype of connective tissue diseases known as calcinosis cutis. The disease is described as diffuse calcium salt deposits in subcutaneous, fibrous muscle structures, and tendons. Calcinosis cutis typically occurs secondary to a tissue damaging disease such as dermatomyositis, systemic lupus erythematosus, and Sjogren syndrome, presenting before age 20 and predominantly affecting women. Calcinosis universalis presents challenges for anesthesia providers as joint calcification can make positioning difficult, vascular access becomes increasingly difficult over time as iatrogenic calcifications limit access sites, and pharyngeal and epiglottic structures can be involved leading to obstruction of the airway. However, anesthesia management of these patients has rarely been reported in the literature. We present a patient with calcinosis universalis with reported difficult airway who was scheduled for endoscopic ultrasound guided biopsy necessitating general anesthesia.

A Randomized Controlled Trial of Anesthesia Guided by Bispectral Index Versus Standard Care: Effects on Cognition.

Postoperative cognitive dysfunction, a subtle deterioration of cognitive function after exposure to anesthetics, is reported in 10% to 50% of surgical cases. Delivery of excessive inhalation anesthetics based on minimum alveolar concentration produces greater deep hypnotic times, which may contribute to postoperative cognitive dysfunction. This study tested the impact on cognitive function of balanced anesthetic using electroencephalographic (EEG) guidance vs usual anesthesia. We studied 88 surgical patients: 45 randomly assigned to balanced anesthetic technique with EEG guidance and 43 to standard treatment. Cognitive function was evaluated with the Cambridge Neuropsychological Test Automated Battery-Mild Cognitive Impairment at 3 intervals (preoperatively, 3-5 days postoperatively, and 3-5 months postoperatively). Additionally, 37 age- and sex-matched individuals not undergoing surgery or anesthesia were evaluated at the same intervals. Better outcomes were seen in the intervention group compared with usual care in the short-term/visual memory cognitive domain (P = .02) at 3 to 5 days, but not at 3 to 5 months. Delivery of anesthesia using EEG monitoring systems can reduce cumulative deep hypnotic time without negatively affecting patient physiologic stress, surgical conditions, or cognitive function. Our findings provide data to support optimal anesthetic approaches to improve cognitive function after anesthesia with volatile anesthetics.

Postdischarge nausea and vomiting: management strategies and outcomes over 7 days.

PURPOSE: The purpose of this study is to determine patient management strategies and outcomes for self-care of postdischarge nausea and vomiting (PDNV). DESIGN: Prospective, comparative, descriptive, and longitudinal study. METHODS: The sample consisted of 248 patients aged 18 years or older undergoing a procedure requiring general anesthesia. Patients recorded incidence and severity of nausea and vomiting, the impact of symptoms, and actions taken to alleviate symptoms for 7 days postdischarge. FINDINGS: The prevalence of PDNV was 56.9%. The methods used to relieve symptoms included antiemetic use by a minority and nonpharmacologic techniques of self-management by some. The effect of nausea on QOL, patient functioning, and patient satisfaction was significantly worse for those who experienced postdischarge nausea on all days. CONCLUSION: Patients with PDNV use minor self-care strategies to manage symptoms. The presence of PDNV affects overall quality of life, patient functioning, and patient satisfaction.
