Loten C, Stokes B, Worsley D; m.fl. (2006). «“A randomised controlled trial of hot water (45°C) immersion versus ice packs for pain relief in bluebottle stings”.184: 329-333.». Med J Aust.CS1-vedlikehold: Eksplisitt bruk av m.fl. (link)CS1-vedlikehold: Flere navn: forfatterliste (link)In a comparison test of hot versus cold therapy conducted at Surf lifesaving first aid facilities at two beaches in eastern Australia from 30 December 2003 to 5 March 2005, they found that immersion in water at 45°C for 20 minutes is an effective and practical treatment for pain from bluebottle stings. An amount of 49 patients received hot water immersion and 47 received ice packs. The two groups had similar baseline features, except patients treated with hot water had more severe initial pain (VAS [mean ± SD]: 54 ± 22 mm versus 42 ± 22 mm). After 10 minutes, 53% of the hot water group reported less pain versus 32% treated with ice (21%; 95% CI, 1%–39%; P = 0.039). After 20 minutes, 87% of the hot water group reported less pain versus 33% treated with ice (54%; 95% CI, 35%–69%; P = 0.002). The trial was stopped after the halfway interim analysis because hot water immersion was shown to be effective (P = 0.002). Hot water was more effective at 20 minutes in nematocyst-confirmed stings (95% versus 29%; P = 0.002). Radiating pain occurred less with hot water (10% versus 30%; P = 0.039). Systemic effects were uncommon in both groups.
«A Randomized, Controlled Field Trial for the Prevention of Jellyfish Stings With a Topical Sting Inhibitor 13: 166-171». J Travel Med. 2006.The effectiveness has also been studied in a controlled field study by the University of Minnesota, Minneapolis, USA. The topical jellyfish sting inhibitor is effective at preventing jellyfish stings in the setting of a field trial in the Gulf of Mexico and Caribbean. The field efficacy of the sting inhibitor was similar to the prior laboratory established efficacy; thus, laboratory studies are comparable to real world results. The results from a field efficacy study demonstrates a relative risk reduction of 82% (95% confidence interval: 21% – 96%; p = 0.02).[død lenke]
