Orthopaedic Residents' Transfer of Knee Arthroscopic Abilities from the Simulator to the Operating Room.

INTRODUCTION: The ultimate goal for any surgical simulation program is to prove the capability of transferring the skills learned to real-life surgical scenarios. We designed an arthroscopic partial meniscectomy (APM) training program and sought to determine its ability to transfer skills to real patients. METHODS: Eleven junior orthopaedic residents and three expert knee surgeons were included. A low-fidelity knee simulator was used. Trainees had two baseline assessments of completing APM on a supervised real patient and on the simulator, measured using the Arthroscopic Surgical Skill Evaluation Tool (ASSET). After baseline, the trainees completed an APM training program and had a final evaluation of proficiency on the simulator and in real patients. Experts were also assessed for comparison. Statistical analysis was performed, assuming nonparametric behavior of variables. RESULTS: All trainees improved from a base score of 14 points in real patients and 10 points on the simulator to a final score of 39 points and 36 points, respectively (P < 0.01). The final trainee simulator score did not differ from experts on the simulator and was lower in real patients (36 versus 39 points, respectively, P ≤ 0.01), which resulted in a 92% transfer ratio for the simulator. DISCUSSION: Simulated training of APM in orthopaedic residents using a low-fidelity knee simulator proved to not only improve simulated proficiency but also successfully transfer skills to a real clinical scenario with a high model transfer ratio. LEVEL OF EVIDENCE: Level II (Prospective Cohort Study).

Postoperative Anticholinergic Poisoning: Concealed Complications of a Commonly Used Medication.

BACKGROUND: Scopolamine is a potent anticholinergic compound used commonly for the prevention of postoperative nausea and vomiting. Scopolamine can cause atypical anticholinergic syndromes due to its prominent central antimuscarinic effects. CASE REPORT: A 47-year-old female presented to the emergency department (ED) 20 h after hospital discharge for a right-knee meniscectomy, with altered mental status (AMS) and dystonic extremity movements that began 12 h after her procedure. Her vital signs were normal and physical examination revealed mydriasis, visual hallucinations, hyperreflexia, and dystonic movements. Laboratory data, lumbar puncture, and computed tomography were unrevealing. The sustained AMS prompted a re-evaluation that revealed urinary overflow with 500 mL of retained urine discovered on ultrasound and a scopolamine patch hidden behind her ear. Her mental status improved shortly after patch removal and physostigmine, with complete resolution after 24 h with discharge diagnosis of scopolamine-induced anticholinergic toxicity. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although therapeutically dosed scopolamine transdermal patches rarely cause complications, incomplete toxidromes can be insidiously common in polypharmacy settings. Providers should thoroughly evaluate the skin of intoxicated patients for additional adherent medications that may result in a delay in ED diagnosis and curative therapies. Our case, as well as rare case reports of therapeutic scopolamine-induced anticholinergic toxicity, demonstrates that peripheral anticholinergic effects, such as tachycardia, dry mucous membranes, and hyperpyrexia are often not present, and incremental doses of physostigmine may be required to reverse scopolamine's long duration of action. This further complicates identification of the anticholinergic toxidrome and diagnosis.
