Review Case Reports
Postoperative hypotonia in a patient with stiff person syndrome: a case report and literature review.
Stiff person syndrome (SPS), an autoimmune disease that manifests with episodic muscle rigidity and spasms, has anesthetic considerations because postoperative hypotonia may occur. This hypotonia has been linked to muscle relaxants and volatile anesthetics and may persist in spite of neostigmine administration and train-of-four (TOF) monitoring suggesting full reversal. We present a patient with SPS who experienced hypotonia following total intravenous anesthesia (TIVA), which was promptly reversed with sugammadex. These observations are considered in light of the relevant medical literature. ⋯ Patients with SPS may show hypotonia regardless of general anesthetic technique (TIVA vs inhalational anesthesia), which can persist despite recovery of the TOF ratio and may be more effectively reversed by a chelating agent than with an anticholinesterase. If general anesthesia is required, we suggest a cautious approach to administering muscle relaxants including using the smallest dose necessary, considering the importance of clinical assessment of muscle strength recovery in addition to TOF monitoring, and discussing postoperative ventilation risk with the patient prior to surgery.

SARS-CoV-2 vaccines have been proven effective at preventing poor outcomes from COVID-19; however, voluntary vaccination rates have been suboptimal. We assessed the potential avoidable intensive care unit (ICU) resource use and associated costs had unvaccinated or partially vaccinated patients hospitalized with COVID-19 been fully vaccinated. ⋯ Unvaccinated patients with COVID-19 had substantially greater rates of ICU admissions, ICU bed-days, and ICU-related costs than vaccinated patients did. This increased resource use would have been potentially avoidable had these unvaccinated patients been vaccinated against SARS-CoV-2.

Individuals in late pregnancy are at risk of significant hemodynamic variations, especially during Cesarean delivery. Although non-invasive monitoring might enable the early detection of variations in cardiac output (CO), clinical validation is lacking. ⋯ gov (NCT03735043); registered 8 November 2018.

Wait list times for total joint arthroplasties have been growing, particularly in the aftermath of the COVID-19 pandemic. Increasing operating room (OR) efficiency by reducing OR time and associated costs while maintaining quality allows the greatest number of patients to receive care. ⋯ Spinal anesthesia in the context of a dedicated block room reduced both anesthesia-controlled time and total OR time. This did not translate into a reduction in incremental cost in the spinal anesthesia group.
