A&A practice

A 60-year-old woman with a 5-year history of anxiolytic use, a diazepam-equivalent daily dose of 15 mg, was scheduled for esophageal stent removal. She was given remimazolam (0.5 mg/kg) but remained fully alert. She only lost consciousness with propofol (40 mg). ⋯ He was given remimazolam (0.3 mg/kg) but remained fully alert. He only lost consciousness after desflurane inhalation. In a patient with a history of long-term benzodiazepine use, anesthetic or sedative agents aside from remimazolam should be considered.

Recent studies have demonstrated that vasopressors can be delivered safely through peripheral intravenous lines. While norepinephrine is usually delivered at a concentration of 16 to 32 μg/mL, out of concern for extravasation and interstitial necrosis, some patients receive more dilute norepinephrine solutions through peripheral intravenous catheters. ⋯ After the incident, the institutional policy changed to recommend normal saline as the default diluent for peripheral norepinephrine, with a more concentrated option available. The incident also informed similar guidelines at other hospitals.

Neonatal airways present unique management challenges that can be compounded by limitations of an underresourced facility. While little clinical data exist on the safety and efficacy of stylet use, they are commonly utilized to facilitate endotracheal intubation in neonates and anticipated difficult airways. As pediatric airway equipment is often understocked in hospitals, innovative thinking can provide creative solutions to these shortages. We present the use of a 16-gauge intravenous catheter as an intubating stylet for a 2.0-millimeter endotracheal tube in the management of a difficult airway in the neonatal intensive care unit.

Celiac plexus neurolysis has been associated with orthostatic hypotension but has not been quantified prospectively or evaluated for persistence after the immediate postprocedural period. Our objective was to quantify persistent hemodynamic changes induced by celiac plexus neurolysis. In this case series of 16 patients with cancer, 8 (50%) had orthostatic hypotension alone, 3 (18.75%) developed an exaggerated postural heart rate increase (>30 beats per min), and 1 (6.25%) had both orthostatic hypotension and an increased heart rate. While the analgesic benefit of celiac plexus neurolysis is clear, the observed hemodynamic changes may be poorly tolerated in some individuals.

A 6-year-old male undergoing bilateral hydrocelectomy was to receive caudal analgesia after induction of general anesthesia. After insertion of the caudal needle, cerebrospinal fluid was unexpectedly aspirated and the caudal was abandoned. The surgeon performed bilateral ilioinguinal nerve blocks just before incision. ⋯ A lumbosacral magnetic resonance imaging (MRI) revealed a sacral meningocele. By the next morning, quadriceps function had returned, and he was ambulating normally. The ilioinguinal block was most likely deep to the internal oblique muscle and produced femoral nerve dysfunction.
