Intravenous fluid resuscitation keeping in mind that blood loss should preferably be replaced with blood. Always insert two wide bore IV cannulae in these patients.
Appropriate use of blood and blood products. Think about activating the Major Haemorrhage Protocol (MHP).
Insert a chest drain, connecting the drain to a cell salvage/saver machine for autotransfusion purposes (image right – Fig 10: Cell salvage/saver machine). If a cell saver is not readily available then prepare the usual drainage apparatus, but prime the underwater seal with saline not sterile water. The saline/blood collection can still be run through a cell saver later.
Occasionally a massive haemothorax may be well tolerated, typically in young patients with a chest stabbing. Delaying chest drain insertion until reaching thoracic theatre, where cell salvage exists, is an option.
Whilst a guideline for thoracotomy exists (see table below), have a low threshold for engaging thoracic surgeons early.
ATLS indications for thoracotomy [2]
Prompt drainage of 1500 ml blood, or a third of the patient’s circulating volume
