Contusions May Coalesce To Form An Intracerebral Hematoma. TBI/ICH - HTML

This document discusses several medical topics: 1) Intracerebral hematomas can form when brain contusions merge together. 2) Narrowed pulse pressure is not seen in neurogenic shock. 3) Escharotomy surgery divides nonviable burned skin to relieve burn-induced compartment syndrome and prevent tissue death. 4) Multilumen esophageal airways can provide airways when definitive airways aren't possible, but must be removed after assessment. 5) Diagnostic peritoneal lavage may show false negatives for diaphragmatic injuries if bleeding is isolated in the lesser sac.

Escharotomy is the surgical division of the nonviable eschar, which allows the cutaneous
envelope to become more compliantFull-thickness circumferential and near-
circumferential skin burns result in the formation of a tough, inelastic mass of burnt tissue
(eschar). The eschar, by virtue of this inelasticity, results in the burn-induced compartment
syndrome. This is caused by the accumulation of extracellular and extravascular fluid
c within confined anatomic spaces of the extremities or digits. The excessive fluid causes the
intracompartmental pressures to increase, resulting in collapse of the contained vascular
and lymphatic structures and, hence, loss of tissue viability. The capillary closure pressure
of 30 mm Hg, also measured as the compartment pressure, is accepted as that which
requires intervention to prevent tissue deat .

Multilumen Esophageal Airway Multilumen esophageal airway devices are used by some prehospital personnel to achieve an
airway when a definitive airway is not feasible (n FIGURE 2-9). One of the ports communicates with the esophagus and the
other with the airway. The personnel who use this device are trained to observe which port occludes the esophagus and which
provides air to the trachea. The esophageal port is then occluded with a balloon, and the other port is ventilated. A CO2 detector
improves the accuracy of this apparatus. The multilumen esophageal airway device must be removed and/or a definitive airway
provided after appropriate assessment.
When diagnostic peritoneal lavage (DPL) is used to detect diaphragmatic injury, a false-negative result may occur
An isolated penetrating injury from the chest can cause bleeding into the lesser sac, which may not communicate with
the rest of the peritoneal cavity. A DPL in this situation would show no evidence of bleeding.
Drainage of lavage fluid from the chest tube has been reported and is a positive result.
