Lung cancer

• Small cell
• Non small cell
• Squamous
• Adeno
• Large cell
• Undifferentiated

12
Lung cancer

• Except for small cell carcinoma of the lung it is
  generally accepted that surgery is the most
  effective therapy for lung carcinoma

Assessment of Patient

• Fitness for surgery
• Operability of the tumour - Staging

15
Staging

• TNM
• T size and position of tumour
• N lymph node status
• M metastasis

16
Stages

• Stage GroupingTNM Subsets
• Stage 0 (TisN0M0)
• Stage IA (T1N0M0)
• Stage IB (T2N0M0)
• Stage IIA (T1N1M0)
• Stage IIB (T2N1M0, T3N0M0)
• Stage IIIA (T3N1M0), (T(13)N2M0)
• Stage IIIB (T4, Any N, M0) (Any T, N3M0)
• Stage IV (Any T, Any N, M1)

Chest drains

• What are they ?
• Why use them ?
• Suction and its role
• What drain do you take out MARK IT

47
(No Transcript)
48
Function

• Conduit to remove fluid or air from the pleural
  or pericardial spaces
• The fluid may be blood, pus or pleural effusion
• Allow the lungs and heart to work unrestricted

49
Spaces That Need Draining Following Thoracic
Surgery

• Only a single pleural cavity opened
• Air and blood may collect in the space
• Two drains
• Apical drain Air
• Basal drain Blood
• Traditionally apical drain is placed anteriorly
  and basal drain at the back

50
Chest Drain
51
Suction

• What does it do?
• Makes the external pressure negative
• Air or blood drains more easily out of chest
• Dangers
• If on to high tissues may get sucked into the
  drain damaging them
• If connected but not on similar effect to
  clamping the drains
• BEWARE PNEUMONECTOMY

52
Does and Donts of Chest Drains

• Do not clamp a functioning drain as this can lead
  to a tamponade or a tension pneumothorax
• If becomes disconnected, reconnect and ask
  patient to cough
• Always keep drain below level of patient
• If raised above patient the contents may siphon
  back into the chest

53
Drain Removaland Timing of Drain Removal
54
On Expiration

• Pleural pressures at their highest
• But still less than atmospheric pressure
• Difficult to hold breath at full expiration
• Natural reaction to pain is to take a deep breath
  in

55
On Inspiration

• Easy to hold breath on maximal inspiration
• Pleural pressure most negative therefore air more
  likely to move into pleural space

56
Valsalva Manoeuvre

• Forced expiration against a closed glottis
• Creates a positive intrapleural pressure
• Easy for patient to hold

57
Post operative care

• Blood pressure
• Blood gases / saturation
• Urine output
• Bleeding
• Sputum
• Analgesia
