CT abdomen

You decide to obtain a CT of Charlie’s abdomen to better identify the cause of her pain. You contact the radiologist and they agree to do the imaging in the evening, when there has been a cancellation. They ask that you keep Charlie ‘nil by mouth’ until then, and suggest that you site a naso-gastric tube.

You explain the plan to the nursing staff and to the mother. Charlie’s mother is pleased that this problem is being taken seriously but wants to take her home as soon as she is better. Charlie is admitted to the ward and intravenous 0.9% NaCl with 5% glucose is started. A naso-gastric tube is inserted and large amounts of green fluid is aspirated.

Intermittently Charlie appears to develop spasms of pain that last for 5-10 minutes before abating. At one stage the nurses ask you if they need to call the arrest team again because she has become so pale and lifeless, but she has a good pulse and when you see her she has recovered. You prescribe some intravenous paracetamol.

In the evening you review her. She has not yet had the CT scan. The nurses say that she has passed a blood, mucousy stool. Charlie is now less alert than before and not interested in her surroundings. She is pale with a capillary refill time of 3-4 seconds. HR is 185/min, RR 45/min.

Meanwhile some more results have come back, sent by a colleague earlier.

When you contact the CT scanning room, you find out that they are running behind schedule and will not be able to scan her until the morning. They suggest an ultrasound instead.
