Disease Management
A week after an elective colectomy, a 70yr old man developed septic shock and multiorgan failure secondary to anastomotic breakdown. He was managed according to surviving sepsis guidelines with source control, early antibiotics, fluids and noradrenaline. The patient remained hypotensive and refractory to noradrenaline therapy, and had vasopressin and low dose hydrocortisone infusion commenced.

A 47-year-old male was admitted to the intensive care unit (ICU) following a high-speed motorcycle accident. He had a number of injuries including bilateral pneumothoraces, multiple spinal fractures, an open-book pelvis fracture, and a brachial plexus injury. Bilateral chest drains were inserted and external fixation of the pelvis was performed. The patient was extubated eventually at day 15 but required reintubation within 12 hours because of a poor cough and sputum retention

A 54 year old man with a history of alcohol excess was admitted under the medical team with an upper gastro-intestinal bleed. He had a background of pulmonary fibrosis that limited his exercise tolerance to 30 yards. Antibiotics, terlipressin and fluid resuscitation, including blood, were given. An oesophago-gastro-duodenoscopy demonstrated severe portal gastropathy but no active bleeding or varices. An abdominal ultrasound demonstrated cirrhosis and some moderate ascites. On day two of the patient’s hospital admission he was admitted to the intensive care unit (ICU) with respiratory failure and non-invasive ventilation was started. Over the next few days his condition deteriorated and he required vasopressor support. By day 6 the patient was oliguric, and his creatinine had risen from 102 to 155 µmoles/l.

A 40 year old lady was admitted under the medical team with pneumonia. She was normally well with no history of respiratory illnesses. On day two of her hospital admission she became more hypoxic necessitating continuous-positive-airway-pressure. Her condition rapidly worsened and her chest x-ray showed diffuse bilateral infiltrates. An echocardiogram demonstrated normal systolic function. She was intubated and ventilated. Despite sedation, ARDSnet ventilation, paralysis and then proning her, she remained severely hypoxaemic. A therapeutic bronchoscopy was performed prior to proning but did not improve her condition.
Should she be referred for consideration of ECMO and was is this evidence to support it’s use?
A patient with polytrauma develops compartment syndrome with an ischaemic leg 24hrs into his admission. He undergoes revascularisation and fasciotomies, but develops rhabdomyolysis and acute kidney injury with a CK that peaks at over 100,000.
Is there a role for mannitol and bicarbonate in the management of his rhabdomyolysis and AKI?Read More »
A 65 year old woman developed a left lower lobe hospital acquired pneumonia following a elective laparoscopic procedure for which she was ventilated for 4 days. Twenty four hours post extubation, she developed hypoxic respiratory failure with bilateral patchy shadowing on chest X-ray. She was reintubated and subsequently grew Pseudomonas aeruginosa from tracheal aspirate.

A young woman was admitted with respiratory failure requiring invasive ventilation. She had bilateral lobar consolidation and positive urinary pneumococcal antigen. She was ventilated with protective lung strategies but required FiO2 of between 0.8-1.0. A PEEP of 18 was set. She was ventilated for over 2 weeks, and was tracheostomised but was discharged from the ICU after 3 weeks.

A cardiovascularly fit 65 year old man was admitted with septic shock secondary to community acquired pneumonia, which progressed to multi-organ failure. During his recovery it was noted that he had generalised weakness with no focal neurology. He underwent respiratory weaning, and rehabilitation therapy over the next 4 weeks but had persistent weakness at his ICU discharge.

A 28 year old male presented to the Emergency Department with an upper gastrointestinal bleed. This was managed with resuscitation and endoscopic diathermy and adrenaline injection This was his first presentation to secondary care with complications from his significant alcohol intake. He reported drinking at least 50 units of alcohol per week. Ultrasound examination demonstrated an enlarged liver with changes consistent with steatosis. On day 3 of his admission, he became tachycardic, tachypnoeic and increasingly lethargic. Examination revealed jaundice, bi-basal lung crepitations and mild confusion. Investigation confirmed an acute hepatitis by blood chemistry and repeat ultrasound. In the absence of any other cause, a diagnosis of acute alcoholic hepatitis was considered.

A 55 yr old man developed severe necrotizing pancreatitis with multiorgan failure. One week into his illness he had developed multiple intra-abdominal collections and had high intra-abdominal pressures. Initial conservative management failed, percutaneous drainage of his collections failed to reduce the abdominal pressures, and he underwent decompressive laparotomy.
What is the evidence behind the current guidelines for the measurement of intra-abdominal hypertension and the use of decompressive laparotomy in the management of Abdominal Compartment Syndrome?Read More »
