Efficacy of ginger as antiemetic in children with acute gastroenteritis: a randomised controlled trial

BACKGROUND

Ginger is a spice with a long history of use as a traditional remedy for nausea and vomiting. No data on the efficacy of ginger are presently available for children with vomiting associated with acute gastroenteritis (AGE).

AIM

To test whether ginger can reduce vomiting in children with AGE.

METHODS

Double-blind, randomised placebo-controlled trial in outpatients aged 1 to 10 years with AGE-associated vomiting randomised to ginger or placebo. The primary outcome was the occurrence of ≥1 episode of vomiting after the first dose of treatment. Severity of vomiting and safety were also assessed.

RESULTS

Seventy-five children were randomised to the ginger arm and 75 to the placebo arm. Five children in the ginger arm and 4 in the placebo arm refused to participate in the study shortly after randomisation, leaving 70 children in the ginger arm and 71 in the placebo arm (N = 141). At intention-to-treat analysis (N = 150), assuming that all children lost to follow-up had reached the primary outcome, the incidence of the main outcome was 67% (95% CI 56 to 77) in the ginger group and 87% (95% CI 79 to 94) in the placebo group, corresponding to the absolute risk reduction for the ginger versus the placebo group of -20% (95% CI -33% to -7%, P = 0.003), with a number needed to treat of 5 (95% CI 3 to 15).

CONCLUSION

Oral administration of ginger is effective and safe at improving vomiting in children with AGE.

Vomiting Children: It's Not Always Gastroenteritis

Emesis is a common presentation in children. Many diagnostic considerations need to be made in a child with emesis and no diarrhea, particularly if lasting longer than 24 hours. The differential diagnosis includes trauma, increased intracranial pressure, obstruction, and metabolic abnormalities such as diabetic ketoacidosis. Prompt recognition with appropriate testing and management is needed. [Pediatr Ann. 2020;49(5):e233-e241.].

Intestinal ascariasis at pediatric emergency room in a developed country

Ascaris lumbricoides infection is rare among children in developed countries. Although large numbers of adult Ascaris in the small intestine can cause various abdominal symptoms, this infection remains asymptomatic until the number of worms in the intestine considerably increases in most cases. Ascaris causing bilious vomiting suggesting ileus is rare, especially in developed countries. A 6-year-old boy who lived in Japan, presented with abdominal colic, bilious vomiting at the pediatric emergency room. He appeared pale, and had no abdominal distention, tenderness, palpable abdominal mass, or findings of dehydration. He experienced bilious vomiting again during a physical examination. Laboratory tests showed mild elevation of white blood cells and C-reactive protein levels. Antigens of adenovirus, rotavirus, and norovirus were not detected from his stool, and stool culture showed normal flora. Ultrasonography showed multiple, round-shaped structures within the small intestine, and a tubular structure in a longitudinal scan of the small intestine. Capsule endoscopy showed a moving worm of Ascaris in the jejunum. Intestinal ascariasis should be considered as a cause of bilious vomiting in children, even at the emergency room in industrial countries. Ultrasound examination and capsule endoscopy are useful for diagnosis of pediatric intestinal ascariasis.
