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.

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.

A proof of concept study was conducted to implement an automated preoperative triage and preparation service with 2 components: (1) triage between preoperative visits and phone screens, and (2) delivery of preoperative instructions to patients. The study enrolled 2604 patients, of whom 75.7% completed the preoperative triage questionnaire and 47.6% were triaged to preoperative phone screens. For the preoperative preparation component, 90.8% of patients viewed surgery preparation instructions, and average patient satisfaction score was 9.3/10. An automated preoperative triage and preparation service can facilitate preoperative triage using patient self-reported information and guide patient preparation with instructions delivered at relevant times.

Lean Six Sigma (LSS) is a process improvement strategy used in many industries. Its goal is to improve performance and quality by eliminating waste, optimizing flow, and reducing variability. ⋯ Incorporating LSS-driven changes resulted in a revised workflow, which decreased personnel workload and significantly reduced delivery time. We hope this article will encourage other health care institutions to integrate LSS strategies into their workflows.
