Tranexamic acid and rFVIIa in Major Obstetric Haemorrhage

Tranexamic acid and rFVIIa in Major Obstetric Haemorrhage

ICM Case SummariesLeave a comment

A 40yr old multiparous woman required an emergency Caesarean section, during which she had a 3.5L blood loss requiring a B-Lynch suture, a Rusch balloon and 4 units of packed red cells. She suffered a further 1.5L postpartum vaginal bleed, returned to theatre and underwent a subtotal hysterectomy during which she received a massive transfusion. Postoperatively, she had a further 1.5L bleed and had a Rusch balloon reinserted. She was given recombinant Factor VIIa and regular tranexamic acid. Haemostasis was achieved and she left hospital with her healthy baby boy 8 days later.

Critical Care Echocardiography

Critical Care Echocardiography

ICM Case SummariesLeave a comment

A 34 year old IV drug abuser was admitted with respiratory failure, bilateral patchy changes on chest X-ray, raised inflammatory markers and septic shock. She was intubated and commenced on antibiotics and noradrenaline. An in-house Focussed Intensive Care Echo was performed to guide fluid resuscitation. This was suggestive of hypovolaemia, but a large mobile mass was also observed in the left ventricular chamber. A departmental echo the next day confirmed the presence of a large vegetation on the anterior mitral valve leaflet with severe mitral regurgitation. She underwent a further period of stabilisation and underwent a mitral valve replacement.

Glycaemic Control on the ICU

Glycaemic Control on the ICU

ICM Case SummariesLeave a comment

A 76 year old man with no comorbidities was admitted to the intensive care unit following an oesophagectomy. During routine blood sugar monitoring, his blood glucose was found to be just over 10 for two consecutive readings so he was commenced on a variable rate insulin infusion. Six hours later, despite hourly monitoring, he had a blood sugar of 3.6. The insulin infusion was stopped and his blood sugar rose back to normal levels. He suffered no apparent ill effects from his hypoglycaemic episode.

Neuroprognostication after Cardiac Arrest

Neuroprognostication after Cardiac Arrest

ICM Case SummariesLeave a comment

A 30 year old man suffered a 30 minute cardiorespiratory arrest secondary to an asthma attack. He was resuscitated, had his severe bronchospasm managed and he was treated with therapeutic hypothermia at 33 degrees. Once rewarmed, his neurology was assessed over several days. He was ventilated on a spontaneous mode, but his pupils remained fixed and dilated and there was no higher motor function seen. A CT brain was consistent with severe hypoxic ischaemic injury. After discussion with the family, treatment was withdrawn.

How reliable is neuroprognostication after cardiac arrest? What modalities are tested? Is there a difference in patients treated with therapeutic hypothermia?

Enteral vs Parenteral Feeding on ICU

Enteral vs Parenteral Feeding on ICU

ICM Case SummariesLeave a comment

A middle aged woman presented with an acute abdomen. At laparotomy she was found to have generalised peritonitis secondary to small bowel perforation due to adhesional obstruction. She remained ventilated and on noradrenaline support for several days post-op. Trophic enteral feeds were introduced at 24hrs post-op, but NG aspirates remained high for a further 48 hours despite prokinetics. The decision was made to institute parenteral nutrition if no improvement at day 5 post-op, but was never commenced as NG aspirates improved and enteral nutrition was gradually increased.

What is the evidence for enteral versus parenteral feed as a source of nutrition in critical ill patients?Read More »

Necrotising Fasciitis - Advances in diagnosis and management

Necrotising Fasciitis – Advances in diagnosis and management

ICM Case SummariesLeave a comment

A 40 year old man underwent a minor elective day case lower limb soft tissue operation. 72 hrs later he began to feel unwell and developed fevers and rigors. He was seen first thing in the morning with increasing pain and inflammation extending up from the foot to the knee. Intravenous antibiotics were started on admission. He was in theatre having a debridement by late morning, by which time the inflammation had spread to the inner thigh. He was in profound septic shock with disseminated intravascular coagulopathy. During the debridement, it was noted that the inflammation had spread to his pelvis. He had a laparotomy and it was determined that the resection he would require was unsurvivable. Treatment was withdrawn and he died on the operating table.

Vasopressin in Septic Shock

Vasopressin in Septic Shock

ICM Case SummariesLeave a comment

An elderly man presented with an acute abdomen. At operation, he was found to have four-quadrant peritonitis due to a perforating sigmoid tumour. He underwent a hemicolectomy and had a defunctioning stoma formed. Postoperatively, he required 0.7mcg/kg/min noradrenaline to maintain a MAP 65mmHg. A vasopressin infusion was commenced and his noradrenaline requirements decreased. However, he developed acute kidney injury and subsequent multiorgan failure. Treatment was withdrawn around 48 hours post-operatively.

Therapeutic Hypothermia after Cardiac Arrest (Peri-TTM)

Therapeutic Hypothermia Post-Cardiac Arrest (Peri-TTM)

ICM Case SummariesLeave a comment

An elderly man was resuscitated from out-of-hospital VF cardiac arrest. He remained deeply comatose post ROSC and was ventilated on the intensive care. His temperature control was not actively managed unless hyperthermia developed. 24 hours post admission he started to have myoclonic jerks and his pupils were fixed and dilated. CT brain showed evidence of severe hypoxic ischaemic injury. Treatment was withdrawn at 72 hours after discussion with family.

ICU Admission with Haematological Malignancy

Outcomes of ICU Admission with Haematological Malignancy

ICM Case Summaries5 Comments

An middle aged woman presented with a blast crisis following acute transformation of preexisting chronic myelomonocytic leukaemia. She failed to respond to several cycles of chemotherapy and underwent allogeneic bone marrow transplant. She subsequently developed neutropaenic septic shock and was found to have fungal pulmonary abscesses. Her sepsis was aggressively managed on ICU and she made steady progress and eventually recovered, and was discharged from hospital 5 weeks after her ICU admission.

What is the current evidence related to the mortality and morbidity associated with admission to intensive care for patients with haematological malignancy?Read More »

ECMO for Severe Refractory Hypoxaemia

ECMO for Severe Refractory Hypoxaemia

ICM Case SummariesLeave a comment

An 60 year old woman developed ARDS secondary to pneumococcal meningitis. Despite optimal ventilatory management and restrictive fluid intake her oxygenation remained severely impaired. She was referred to the regional respiratory failure unit who established her on mobile ECMO for retrieval. She remained on ECMO for five days, weaned off the ventilator after three further days and made a full neurological recovery leaving hospital two weeks later.

Is there sufficient evidence to promote the use of Extracorporeal Membrane Oxygenation (ECMO) for the management of severe refractory hypoxia in the United Kingdom?Read More »
