The Glasgow Coma Scale, being inappropriate for use in children (especially below the age of 5) as they are unable to elicit the verbal response as per the adult GCS. Therefore, GCS for the paediatric age group was modified to Adelaide coma scale (ACS), which is stated as follows:Best Eye Response (as in adult scale):Spontaneous – 4To speech – 3To pain – 2No response – 1Best Verbal Response:Oriented – 5Words – 4Vocal sounds – 3Cries – 2No response – 1Best Motor Response (as in adult scale):Obeys commands – 5Localises pain – 4Flexion to pain – 3 Extension to pain – 2No response – 1 The described child scores:Eye response – 1; Verbal response – 3; Motor response – 4Thus, bringing the total ACS score to 8.

NICE guidelines suggest that when a child’s single risk factor is 2 vomits, the child should be observed for 4 hours from the time of the injury, instead of having a CT.

Pupils are dilated in patients with amitriptyline overdose.Tricyclic antidepressants have a narrow therapeutic index, and thus, small doses can be fatal in children. Deaths from tricyclics are more common than other antidepressants. Bimodal incidence with toddlers (accidental) and teenagers (deliberate) most commonly affected.Symptoms: They occur within 6 hours of ingestion.- Nausea, vomiting, and headache- Elevated body temperature- Agitation, sleepiness, confusion, coma- Dry mouth, blurred vision, urinary retention (anticholinergic)- Dilated pupils- Seizures- Hypotension, tachycardia, conduction disorders, and cardiac arrest- Respiratory depressionManagement:Treatment focuses on supportive care. This includes airway protection, ventilation and oxygenation, intravenous fluids, and cardiac monitoring.Other measures include:- Activated charcoal within 2 hours- Hypotension is treated with IV fluids and adrenaline- Cardiac monitoring- Sodium bicarbonate in acidosis or if there are wide QRS complex (> 100 ms)- Convulsions may require diazepam or lorazepam.

In children, food-induced anaphylaxis is the most common trigger and accounts for 37 %-85 % of cases, whereas insect bites/stings account for 5 %-13 % and medications account for 5 %-12 % Despite differences between studies, food allergy is clearly the most common cause of anaphylaxis in children

Any 2-month-old child presenting with any of the above signs, should be assessed and have a history taken and physical examination made before discharge. As these may all be signs and symptoms for a condition requiring hospitalisation.

Diazepam given rectally may be helpful in treating prolonged convulsions outside and within hospital when intravenous injection is not possible. A rectal dose of 0.5 mg/kg (maximum 10 mg) of injectable diazepam, undiluted or diluted with a 50% propylene glycol solution, can stop seizures in up to 80% of children. There are few adverse reactions. Seizures in children usually cease spontaneously within 5-10 minutes and are rarely associated with significant sequelae. The chance of a seizure stopping spontaneously decreases significantly after 10-15 minutes. Similarly, the efficacy of anticonvulsant medication decreases after 10-15 minutes of fitting and the risk of adverse effects increases. Convulsive seizures lasting longer than 30 minutes constitute status epilepticus and may be complicated by cardio respiratory depression and brain injury. Diazepam or clonazepam, given intravenously, is generally the drug of choice for the emergency treatment of convulsive status epilepticus. Intravenous diazepam may be difficult to administer to the young convulsing child and, because of the need for intravenous access, is not ideal for rapid treatment in the community by non-medical carers.

Meckel’s diverticulum is a true diverticulum and is the most common congenital anomaly of the GI tract, occurring in about 2% of people. It is caused by incomplete obliteration of the vitelline duct and consists of a congenital sacculation of the antimesenteric border of the ileum. Symptoms are uncommon but include lower GI bleeding, bowel obstruction, and inflammation (diverticulitis). Causes of upper GI bleeding in neonates:Swallowed maternal bloodCoagulopathies including haemorrhagic disease of the new-bornStress gastritis & stress ulcersDrugs (NSAIDs, heparin, indomethacin used for patent duct closure, dexamethasone)Causes of upper GI bleeding in children 1 month to 1 year:GORDGastritis (with or without Helicobacter pylori infection)Crohn diseaseDrugs (NSAIDs)Zollinger-Ellison syndromeCauses of upper GI bleeding in children 1 -2 years:Peptic ulcer diseaseZollinger-Ellison syndromeBurns (Curling ulcer)Head trauma (Cushing ulcer)SepsisCauses of upper GI bleeding in older than 2 years:Oesophageal varices secondary to portal hypertension (most commonly portal vein thrombosis and biliary atresia)Duodenal ulcersOesophagitisGastritisMallory-Weiss tears

Intussusception is one of the common causes of intestinal obstruction in children, resulting from the invagination or telescoping of one segment of the bowel into the other distal segment. It may induce bowel ischemia and necrosis, as well. It can occur as a complication of Meckel’s diverticulum. It usually occurs proximal to the ileocecal valve, and the most common presentation is ileocecal. Early signs and symptoms include cramping abdominal pain, nausea, vomiting, and pulling legs up to chest area. First line treatment includes resuscitation with IV fluids and nasogastric tube. It responds well to air-enema, which is also diagnostic.

The most appropriate step in this patient would be to admit the patient for enteral rehydration via a nasogastric tube.Enteral rehydration:Oral rehydration is the most preferred way of rehydrating children. If a child is not tolerating small-frequent-feeds, then nasogastric rehydration is an underused next best step. The fluid can be run through a continuous pump so that it is better tolerated. Note:Intravenous fluids are effective but can have profound effects on the serum electrolyte balance if not monitored closely. Most children will tolerate fluids in an emergency department, but failure to take fluids orally is not an indication for intravenous therapy.

Intussusception is the invagination of one segment of the intestine within a more distal segment. It presents with vomiting, abdominal pain, and a palpable abdominal mass.Intussusception usually affects infants between 6-18 months old. Boys are affected twice as often as girls
