This clinical presentation is highly suggestive of choking. According to the BLS algorithm, the next step in managing a case of choking in a conscious child with an ineffective cough is five back blows.Other options:- Adrenaline intramuscularly: The history is similar to anaphylaxis, but the absence of a rash or oedema and the acute onset make choking more likely in this situation. Thus, adrenaline will not be of use in this patient.- CPR at a ratio of 15:2: Since the child is conscious, it is not advised. If the child were unconscious, you would commence basic life support.- Five abdominal thrusts: In the given scenario, the child is an infant. Abdominal thrusts are avoided in infants due to the risk of intra-abdominal injury.

All of the presenting features of the child are suggestive raised intracranial pressure. Thus, urgent treatment with 20% Mannitol can improve the child’s condition. Mannitol is an osmotic diuretic that is used in the treatment of raised intracranial pressure. It should be avoided in hypovolaemia because of its diuretic effects. Other options:- Head up at 15°: Keeping the head up at 20° in the midline will aid venous drainage. – Maintain CO2 at 5 kPa: If there is an acute rise in intracranial pressure, then lowering the CO2 to 4–4.5 kPa as a temporary measure can be beneficial. However, this must be only short-lived since it causes vasoconstriction and can impair cerebral blood flow. – 10% glucose bolus: Maintaining normoglycemia in traumatic brain injury is important. – 0.9% saline infusion: Hypertonic saline infusion of 3% can reduce intracranial pressure. 0.9% saline as a bolus could be beneficial if there were hypotension.

Cushing reflex is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing’s triad of increased blood pressure, irregular breathing, and bradycardia. It is usually seen in the terminal stages of acute head injury and may indicate imminent brain herniation. It can also be seen after the intravenous administration of epinephrine and similar drugs.

McBurney’s point is found 2/3rds of the way along an imaginary line that runs from the umbilicus to the anterior superior iliac spine on the right-hand side. On examination, features of generalised peritonitis can be observed if the appendix has perforated.Retrocecal appendicitis may have relatively fewer signs.Digital rectal examination may reveal boggy sensation if a pelvic abscess is present.Diagnosis is typically based on raised inflammatory markers coupled with compatible history, and examination findings.Ultrasound is useful in females where pelvic organ pathology can be a close differential diagnosis. Although it is not always possible to visualise the appendix on ultrasound, the presence of free fluid (always pathological in males) should raise suspicion. Ultrasound examination can also show evidence of luminal obstruction and thickening of the appendix.Management: Definitive management of appendicitis and appendicular perforation is appendicectomy which can be performed via either an open or laparoscopic approach.Simultaneous administration of metronidazole reduces wound infection rates. Patients with perforated appendicitis require copious abdominal lavage. Patients without peritonitis who have an appendix mass should receive broad-spectrum antibiotics and consideration given to performing an interval appendicectomy.

Neurogenic shock is a devastating consequence of spinal cord injury (SCI), also known as vasogenic shock. Injury to the spinal cord results in sudden loss of sympathetic tone, which leads to the autonomic instability that is manifested in hypotension, bradyarrhythmia, and temperature dysregulation. Spinal cord injury is not to be confused with spinal shock, which is a reversible reduction in sensory and motor function following spinal cord injury. Neurogenic shock is associated with cervical and high thoracic spine injury. Early identification and aggressive management are vital in neurogenic shock to prevent secondary spinal injury.

The clinical scenario provided is highly suggestive of third-degree burns (or full-thickness burns) that may have invaded the deeper levels up to dermis, evident from the insensate nature of the lesion.Degrees of Burns:- First degree burns are superficial second-degree burns.- Second-degree burns are just deeper than that of first-degree burns but vary enormously in other properties.- Third-degree burns are full-thickness burns which are leathery in consistency, and insensate. These burns do not heal on their own. The sensory neurons present in the skin at the deeper levels are destroyed completely and hence provide a paradoxical lack of pain.- Fourth-degree burns involving the subcutaneous tissues, tendons, and bones are very difficult to manage.Assessment of the extent of the burns for the treatment employs specialized charts, such as Lund and Browder charts and Wallace rule of nines.The Lund and Browder chart is, however, considered the most accurate.Wallace’s Rule of Nines can be used for children >16 years: – Head + neck = 9%- Each arm = 9%- Each anterior part of leg = 9%- Each posterior part of leg = 9%- Anterior chest = 9%- Posterior chest = 9%- Anterior abdomen = 9%- Posterior abdomen = 9%

The Five P’s: pain, pulselessness, paraesthesia, paralysis, and pallor, are the most common symptoms of compartment syndrome. However, late signs of the condition include the absence of distal pulses.

People aged 16 or over are entitled to consent to their own treatment. This can only be overruled in exceptional circumstances. Children under the age of 16 can consent to their own treatment if they’re believed to have enough intelligence, competence and understanding to fully appreciate what’s involved in their treatment. This is known as being Gillick competent.Otherwise, someone with parental responsibility can consent for them.This could be:the child’s mother or fatherthe child’s legally appointed guardiana person with a residence order concerning the childa local authority designated to care for the childa local authority or person with an emergency protection order for the child.Giving the blood transfusion is therefore both clinically and ethically the right course of action.Jehovah’s Witnesses frequently carry a signed and witnessed Advance Decision Document listing the blood products and autologous procedures that are, or are not, acceptable to them It is appropriate to have a frank, confidential discussion with the patient about the potential risks of their decision and the possible alternatives to transfusion, but the freely expressed wish of a competent adult must always be respected.

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.

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

In an acute and severe asthma attack the child cannot complete sentences in one breath because they are too breathless. The O2 saturation is less than 92% and PEF is between 33-50% best or predicted. In children that are 2-5 years old, HR is more than 140 bpm and more than 125 bpm in those older than 5 years old. The RR in children between 2-5 years old is more than 40/min, and more than 30/min in those older than 5 years old.

Sepsis is a medical emergency that describes the body’s systemic immunological response to an infectious process that can lead to end-stage organ dysfunction and death. The fever, alongside the clinical presentation, make sepsis the likely diagnosis. A temperature >38 degrees in an infant <3months of age warrants investigation.

Possible complications include:- Hearing loss (which may be partial or total)- problems with memory and concentration- problems with coordination and balance- learning difficulties (which may be temporary or permanent)- epilepsy (Seizures)- cerebral palsy- speech problems- vision loss (which may be partial or total)As hearing loss is the most common complication of meningitis people recovering from the condition are usually given a hearing test to assess their hearing.

Answer: Curling’s ulcersCurling’s ulcer is an acute gastric erosion resulting as a complication from severe burns when reduced plasma volume leads to ischemia and cell necrosis (sloughing) of the gastric mucosa. The most common mode of presentation of stress ulcer is the onset of acute upper GI bleed like hematemesis or melena in a patient with the acute critical illness. A similar condition involving elevated intracranial pressure is known as Cushing’s ulcer. Cushing’s ulcer is a gastro-duodenal ulcer produced by elevated intracranial pressure caused by an intracranial tumour, head injury or other space-occupying lesions. The ulcer, usually single and deep, may involve the oesophagus, stomach, and duodenum. Increased intracranial pressure may affect different areas of the hypothalamic nuclei or brainstem leading to overstimulation of the vagus nerve or paralysis of the sympathetic system. Both of these circumstances increase secretion of gastric acid and the likelihood of ulceration of gastro-duodenal mucosa.Mallory-Weiss syndrome is characterized by upper gastrointestinal bleeding secondary to longitudinal mucosal lacerations (known as Mallory-Weiss tears) at the gastroesophageal junction or gastric cardia. However, Mallory-Weiss syndrome may occur after any event that provokes a sudden rise in the intragastric pressure or gastric prolapse into the oesophagus, including antecedent transoesophageal echocardiography. Precipitating factors include retching, vomiting, straining, hiccupping, coughing, primal scream therapy, blunt abdominal trauma, and cardiopulmonary resuscitation. In a few cases, no apparent precipitating factor can be identified. One study reported that 25% of patients had no identifiable risk factors.

Internal abdominal bleeding is most probably the cause of the child’s shock, especially unresponsive to fluid boluses.

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

Febrile seizures are convulsions that can happen when a child, most often between the ages of six months and three years, has a fever. They usually last for less than five minutes and although the child may lose consciousness, they are relatively harmless. However, sometimes they can last for up to 15 minutes and when they are termed complex febrile seizures.

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.

The most appropriate imaging modalities to be used in this child would be CT Head, C-spine and Abdomen/Pelvis and chest X-ray (CXR).The C-spine cannot be cleared, this alongside a multi-trauma presentation means a CT C-spine is indicated rather than X-rays alone. The imaging modality for blunt trauma to the chest is CXR| if this shows significant thoracic trauma, a CT chest should be considered. Other options:- CT Head and Abdomen/Pelvis with CXR and X-ray C-spine: This child is at risk of C-Spine injury following the mechanism of trauma. He had a reduced GCS, has undergone a multi-region trauma and is now intubated. NICE head injury guidelines, therefore, recommend using CT.- CT Head, C-spine and Abdomen/Pelvis X-rays: Imaging of the chest is required following blunt trauma and for endotracheal tube position.- MRI Head: If there were concerns of abnormal neurology, then spinal MRI could be considered.- Whole-body CT: It is not recommended in children in view of the high radiation doses.

Answer: Oculogyric crisisOculogyric crisis is an acute dystonic reaction of the ocular muscles characterized by bilateral dystonic elevation of visual gaze lasting from seconds to hours. This reaction is most commonly explained as an adverse reaction to drugs such as antiemetics, antipsychotics, antidepressants, antiepileptics, and antimalarials. Metoclopramide is a benzamide selective dopamine D2 receptor antagonist that is used as an antiemetic, with side effects that are seen frequently in children.1 The most common and most important side effects of metoclopramide are acute extrapyramidal symptoms, which require immediate treatment. Acute dystonic reactions occur as contractions of the muscles, opisthotonos, torticollis, dysarthria, trismus, and oculogyric crisis.
