Declining Admission to Intensive Care

An 86 year-old man was referred to ICU because of oliguria, acidaemia and decreased conscious level. He had originally been referred by the general practitioner to the acute general medicine team with unexplained weight loss, malaise and reduced mobility, 19 days previously. He had a longstanding history of bronchiectasis and COPD. He had been able to mobilise independently around his house and garden until suffering a pneumonia several months before this admission, and since required a four-times-daily care package.

During the current admission the patient had been treated for a further pneumonia on the basis of new chest x-ray changes, breathlessness and raised inflammatory markers. He had also undergone a CT chest/abdomen/pelvis for the unexplained weight loss. This was consistent with chronic COPD and bronchiectasis but no other positive findings. A week prior to ICU referral he was found to have acute kidney injury (creatinine 280 µmol/mL, baseline 90 µmol/mL) which had failed to improve. In the 24 hours prior to referral had become progressively drowsy and oliguric.

The patient appeared frail, cachectic and oedematous. He groaned in response to voice and could not follow commands. He had Kussmaul breathing at a rate of about 18 breaths per minute with SaO2 of 91% on 35% oxygen via facemask. Arterial blood gas showed pH 7.09, pCO2 7.1 kPa, pO2 9.1 kPa, base excess -9.3 mEq/L, lactate 1.3 mmol/L, glucose 8.7 mmol/L, creatinine 294 µmol/mL. His chest x-ray showed persistent bilateral patchy consolidation. He had a blood pressure of 98/55 mmHg with a pulse of 110 beats/min and cool peripheries. ECG showed sinus tachycardia. He was afebrile. Abdomen was soft and a urinary catheter had drained only 25 mL in the last 4 hours. Other than reduced responsiveness, neurological survey was non-diagnostic.

Evaluation of this patient revealed an elderly man who was severely unwell with acute kidney injury, probable sepsis, and a poor response to treatment to date. This was on the background of chronic suppurative lung disease, and diminished health for several weeks. No specific treatment limitations were in place. His next-of-kin was unaware of any prior expressed wishes and was under the impression that the patient would prefer active treatment. The referring team were of the opinion that intensive care should be considered.

Although no unifying diagnosis for this gentleman’s kidney injury had been identified, a single, rapidly-reversible condition was not apparent. The principal indication for intensive care was for renal replacement therapy for an unknown duration. In view of the status of his neurological, respiratory and cardiovascular systems, it was deemed that airway protection, invasive respiratory support and vasopressor treatment would almost certainly be required. His overall health status made the prospect of survival from a prolonged period of multi-organ support on intensive care highly unlikely. After discussion with the intensive care consultant and the referring consultant it was decided to withhold admission to the intensive care unit. Appropriate family discussions were held. The patient was actively managed on the ward for a further 12 hours, after which fluid management, antimicrobials and further investigation were ceased. He died the following day.

Organ Donation After Cardiac Death

DCD Organ Donation: Eligibility and Contra-indications

A 35 year old man sustained a severe penetrating traumatic brain injury. His injuries were deemed to be unsurvivable, but he was not brainstem dead. He was on the organ donor register, and his family were keen to proceed with donation. He was admitted to the ICU to manage his end of life care and facilitate organ donation after circulatory death.
