A Survey of Ski Patrols in the United States Comparing Medical Direction, Patroller Training, and Patient Care.

INTRODUCTION: Ski patrols are tasked with substantial challenges: distance from definitive care, complex extrications, and winter environments. Rules for US ski patrols stipulate that ≥1 persons be trained in basic first aid, but no further regulations regarding the specifics of provided medical care exist. This project investigated patroller training, patient care, and medical direction of US ski patrols through a survey of ski patrol directors and medical directors. METHODS: Participants were contacted via email, phone, and personal contacts. After consultation with known ski patrol directors and medical directors for question guidance, 2 separate institutional review board-approved surveys were designed: 1 for ski patrol directors and 1 for ski patrol medical directors, containing 28 and 15 qualitative questions, respectively. The surveys were distributed with a link to the encrypted Qualtrics survey platform. After 2 reminders and 4 mo, results were downloaded from Qualtrics into an Excel spreadsheet. RESULTS: Twenty-two responses from patrol directors and 15 from medical directors were received. The response rate is unknown. Outdoor emergency care certification was the minimum medical training required by 77% of the study participants. Twenty-seven percent of surveyed patrols belonged to an emergency medical service agency. Fifty percent of 11 surveyed ski patrols had a medical director, 6 of whom were board certified in emergency medicine. All surveyed medical directors stated that they assisted with patroller education, and 93% assisted with protocol development. CONCLUSIONS: The surveys demonstrated variability in patroller training, protocols, and medical directorship. The authors questioned whether ski patrols would benefit from increased standardization of care and training, quality improvement programs, and medical directorship.

Efficacy of Topical Treatments for Chrysaora chinensis Species: A Human Model in Comparison with an In Vitro Model.

OBJECTIVES: This study sought to create a model for testing topical treatment of jellyfish stings. It sought to determine which treatments 1) stimulate/inhibit nematocyst discharge; 2) decrease pain; and 3) decrease skin inflammation; it also sought to discover whether there is a clinical correlation between stimulated nematocyst discharge observed in vitro to the pain and erythema experienced by humans stung by a particular species of jellyfish, C chinensis. METHODS: Chrysaora chinensis stung 96 human subjects, who were then treated with isopropyl alcohol, hot water, acetic acid, papain meat tenderizer, lidocaine, or sodium bicarbonate. Pain and erythema were measured. In a separate experiment, nematocysts were examined microscopically after exposure to the same topical treatments used in the human experiment. RESULTS: Forearms treated with papain showed decreased mean pain over the first 30 minutes after being stung, relative to placebo, although only by a small amount. The other topical treatments tested did not reach statistical significance. Sodium bicarbonate may reduce erythema after 30 minutes of treatment; sodium bicarbonate and papain may reduce erythema at 60 minutes. The other topical treatments tested did not reach statistical significance. Nematocyst discharge in vitro occurred when tentacles of C chinensis were exposed to acetic acid or isopropyl alcohol. Sodium bicarbonate, papain, heated water, and lidocaine did not induce nematocyst discharge. CONCLUSIONS: Papain-containing meat tenderizer used as a topical treatment for C chinensis stings may decrease pain. Although there is published experimental support for the concept that in vitro nematocyst discharge correlates with in vivo human pain perception, no definitive randomized controlled trial, including ours, has yet provided incontrovertible evidence of this assertion. Despite this study's limitations, it presents a viable basis for future human studies looking at the efficacy of topical treatments for jellyfish stings.
