Trocar chest drains consist of a plastic drain with a radio-opaque
stripe along their length surrounding a metal rod with a sharp end.
They are available in a variety of sizes.
Seldinger (Figure 17.3) chest drains are usually smaller drains
which are inserted by advancing the drain over a guidewire. Studies
have shown that smaller chest drains (10-14F) are often as effective
as larger-bore drains and are better tolerated by patients.
Large-bore drains are recommended for acute haemothorax to
monitor blood loss and may also be necessary if a pneumothorax
has failed to resolve despite a smaller drain.

Ultrasound guidance
Recent research regarding the morbidity and mortality of chest
drain insertion strongly recommends insertion of chest drains
under ultrasound guidance. The ultrasound training required for
this is beyond the scope of this text, but healthcare professionals
who intend to perform this procedure should familiarise them-
selves with this.
Anatomy and positioning of patient
Step-by-step guide: insertion of a Seldinger chest
Chest drains should be inserted within the 'triangle of safety' which
has the following borders (see Figure 17.4):
anteriorly - anterior axillary line, lateral border of pectoralis major
posteriorly - anterior border of latissmus dorsi
Give a full explanation to the patient in simple terms and
inferiorly - at the level of the nipple.
ensure they consent to the procedure.
Set up your trolley (Box 17.1 and Figure 17.5).
Ideally the patient should be positioned on the bed at 45° with
their arm held behind their head to expose the axillary area.
Alternatively, the patient could be sitting forwards and leaning over
a table.
Prepare your trolley as a sterile fi eld. Wear a plastic
disposable apron and sterile gloves, and take alcohol hand
rub with you.
