Ten Years Later, Alarm Fatigue Is Still a Safety Concern.

Ten years after the publication of a landmark article in AACN Advanced Critical Care, alarm fatigue continues to be an issue that researchers, clinicians, and organizations aim to remediate. Alarm fatigue contributes to missed alarms and medical errors that result in patient death, increased clinical workload and burnout, and interference with patient recovery. Led by the American Association of Critical-Care Nurses, national patient safety organizations continue to prioritize efforts to battle alarm fatigue and have proposed alarm management strategies to mitigate the effects of alarm fatigue. Similarly, clinical efforts now use simulation studies, individualized alarm thresholds, and interdisciplinary teams to optimize alarm use. Finally, engineering research efforts have innovated the standard alarm to convey information more effectively for medical users. By focusing on patient and provider safety, clinical workflow, and alarm technology, efforts to reduce alarm fatigue over the past 10 years have been grounded in an evidence-based and personnel-focused approach.

Angioedema: Perioperative management.

OBJECTIVE: To describe the perioperative management of a patient with acquired angioedema (AAE). METHODS: A 66-year-old Caucasian male presented from an outside hospital with a history of acquired angioedema and gastrointestinal stromal tumor-related intractable urticaria and mastocytosis. He was admitted for urgent laparoscopic partial gastrectomy, secondary to gastric outlet obstruction symptomatology. Previous combined attacks were characterized by a widespread rash, abdominal pain and respiratory distress resulting in hospitalization. Following preoperative consultation with the patient's allergist and a hospital pharmacist, he was treated preoperatively with fresh frozen plasma and his home prednisone dose. C1-inhibitor (Berinert®) was on standby along with epinephrine, given that the underlying etiology (C1- inhibitor deficiency vs histaminergic) was not known. RESULTS: There were no intraoperative complications, and the patient was discharged home 3 days after the procedure. CONCLUSIONS: Optimization of perioperative outcomes in patients, especially during urgent or emergent surgery, with a history of angioedema requires the development of a patient-specific perioperative plan, including prophylaxis, rescue therapies and opioid-sparing strategies.

Cryoamputation as a temporizing measure in severe burn injury.

Cryoamputation, or physiologic amputation, is a well-described procedure typically used to amputate gangrenous lower extremities. In such cases the patient is too unstable for transport to the operating room, so cryoamputation using dry ice or other refrigerant allows for immediate bedside intervention and later operative amputation when the patient is more stable. In this study the authors describe the use of cryoamputation to stabilize a burn patient with a nonviable upper extremity considered to be contributing significantly to his metabolic acidosis. This experience suggests that cryoamputation may be a reasonable technique to consider when a burn patient presents with a nonviable extremity but is too unstable for immediate operative amputation.
