Their demographic, consumption and clinical history characteristics are summarised in <a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>.

Regarding the differences between the cases with a single visit and the repeaters, the latter consumed more toxic substances (p = 0.01), specifically more tobacco (p = 0.01) and more cocaine (p = 0.031) (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>).</p><p id="par0065" class="elsevierStylePara elsevierViewall">The drugs used as initial treatment for CHS were the antiemetics ondansetron (52.5%) and metoclopramide (40.7%), omeprazole (30.5%), analgesics such as paracetamol (22%) and metamizole (5.1 %), spasmolytics (scopolamine butylbromide 10.2%) and opiates –tramadol (8.5%), pethidine (6.8%) and fentanyl (3.4%)–. Droperidol was used in 8.5%, haloperidol in 6.8%, and benzodiazepines in 10.2%. Capsaicin was applied in 74.6% of the visits and was not necessary in the rest due to resolution of the clinical symptoms with the previous drugs.</p><p id="par0070" class="elsevierStylePara elsevierViewall">With regard to complementary tests (<a class="elsevierStyleCrossRef" href="#tbl0010">Table 2</a>), fewer abdominal X-rays, ultrasounds and CT scans were requested in repeat patients, although this difference was not significant. Treatment began on average at 173 min, with no differences between the first and successive visits, although this data was only recorded in 83% of the patients. Time to capsaicin application was 254 min. Capsaicin was used less in the repeat group (p = 0.015). The mean time to resolution of vomiting after capsaicin was 17.87 min, ranging from 13.73 for visit zero to 27 for repeaters, although without statistical significance. Conversely, when calculating the overall length of stay in the Emergency Department, repeat patients spent an average of 114.62 min less than the first episodes, although without statistical significance. One case of adverse reaction to capsaicin was recorded, consisting of erythema and intense burning sensation in the area of application (abdomen). Finally, no association was found between the time-course of care for patients with CHS over the 2 years of the study and the decrease in treatment times, nor in the application of capsaicin.</p><elsevierMultimedia ident="tbl0010"></elsevierMultimedia></span><span id="sec0020" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0080">Discussion</span><p id="par0075" class="elsevierStylePara elsevierViewall">This paper presents the first case series of CHS in an ED in Spain.

Furthermore, it was not possible to standardise the dose of capsaicin, nor the area and site of application. Thirdly, as it is a single-center study and in an ED with a clinical toxicology area, it is possible that the data do not represent the reality of the rest of the Spanish or European EDs.</p><p id="par0105" class="elsevierStylePara elsevierViewall">CHS has a low incidence in EDs but has probably been under-diagnosed and should be considered in patients with abdominal pain and vomiting, especially in cannabis users.
