The IAB Counter pulsation system

A flexible catheter -2 lumen bull first - for distal aspirationflushing or pressure monitoring bull second - for the periodic delivery and removal of helium gas to a

closed balloon

17

HEMODYNAMIC EFFECTS mdash Inflation and deflation of the balloon

bull Blood is displaced to the proximal aorta by inflation during bull diastole

bull Aortic volume ( afterload) is reduced during systole through a

vacuum effect created by rapid balloon deflation

18

Expected changes with IABP support in hemodynamic profile in patients with Cardiogenic shock

- Decrease in SBP by 20

- Increase in aortic Diastolic Press by 30 ( raise coronary blood flow)

- Increase in MAP

- Reduction of the HR by 20

-Decrease in the mean PCWP by 20

- Elevation in the COP by 20

IABP catheter

10-20 cm long polyurethane bladder

25cc to 50cc capacity

Optimal 85 of aorta occluded (not 100)

The shaft of the balloon catheter contains 2 lumens - one allows for gas exchange from console to balloon - second lumen - for catheter delivery over a guide wire

- for monitoring of central aortic pressure after installation

STEP BY STEP- IABP insertion

27

Before taking the Catheter out of Tray

28

Take the entire catheter and T handle as one unit

(DO NOT disconnect one-way valve when removing the extracorporeal tubing from the tray)

Pull out the T- handle only as shown

29

bull Remove styletaspirateFlush

bull Insert the balloon only over the guide wire

bull Hold the catheter close to skin insertion point

bull Advance in small steps of 1 to 2 cm at a time and stop if any resistance

bull The IABP should advance freely

Inserting the Balloon catheter

- Many vascular complications occur during insertion itself

- Resistance during insertion either indicates PVOD or dissection

- Kinking of IABP raquo improper inflationdeflation

30

- The end of the balloon should be just distal (1-2 cm) to the takeoff of the left subclavian artery

- Position should be confirmed by fluoroscopy or chest x-ray

Positioning

31

Connecting to console - Connect helium gas tube to the console via a long extender - Open helium tank

- The central lumen of the catheter is flushed and connected to pressure

tubing with 3 way and then to a pressure transducer to allow for monitoring of central aortic pressure

- Zero the transducer

Initial set-up- Once connected properly the console would show ECG and pressure waveforms- Check Basal mean pressure- Make sure the setting is at ldquoautordquo- Usually IABP started at 11 or 12 augmentation- Usually Augmentation is kept at maxim

32

33

Trigger modesTrigger - Event the pump uses to identify the onset of cardiac cycle (systole) - Pump must have consistent trigger in order to provide patient assist - If selected trigger not detected counter pulsation will interrupted

1ECG - uses the slope of QR segment to detect triggering point

2 AP(Arterial pressure wave) - Systolic upstroke of the arterial pressure wave form is the trigger

3 IN(Internal trigger)

34

ECG signal ndash most common bull Inflation - middle of T wave bull Deflation ndash peak of R wave

Factors affecting diastolic augmentationPatient

- Heart rate- Mean arterial pressure- Stroke volume- Systemic vascular resistance

Intra aortic balloon catheter- IAB in sheath- IAB not unfolded- IAB position- Kink in the IAB catheter - IAB leak- Low helium concentration

Intra aortic balloon pump- Timing- Position of IAB augmentation control

Late Inflation Inflation of the IAB markedly after closure of the aortic valve Waveform Characteristics

bull Inflation of IAB after the dicrotic notchbull Absence of sharp V

Sub optimal diastolic augmentation

50

Early Deflation Premature deflation of the IAB during the diastolic phase

51

Late Deflation Late deflation of the IAB during the diastolic phase

Waveform Characteristicsbull Assisted aortic end diastolic pressure may be equal to the

unassisted aortic end diastolic pressurebull Rate of rise of assisted systole is prolongedbull Diastolic augmentation may appear widened

52

Once Arterial waveform is ok check balloon waveform

Normal Balloon Pressure Waveform

53

54

Variation in balloon pressure wave forms

Increased duration ofplateau due to longer

diastolic phase

Decreased durationof plateau due to

shortened diastolicphase

55

Variation in balloon pressure wave forms

Varying R-R intervalsresult in irregularplateau durations

56

Variation in balloon pressure wave forms

Increased heightor amplitude ofthe waveform

Decreased heightor amplitude of thewaveform

57

Variation in balloon pressure wave forms

Gas leak

Leak in the closed system causing theballoon pressure waveform to fall belowzero baseline

- due to a loose connection- a leak in the IAB catheter- H2O condensation in the external tubing- a patient who is tachycardiac and febrile which causes increased gas diffusion through the IAB membrane

58

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

62

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

bull Hold the catheter close to skin insertion point

bull Advance in small steps of 1 to 2 cm at a time and stop if any resistance

bull The IABP should advance freely

Inserting the Balloon catheter

- Many vascular complications occur during insertion itself

- Resistance during insertion either indicates PVOD or dissection

- Kinking of IABP raquo improper inflationdeflation

30

- The end of the balloon should be just distal (1-2 cm) to the takeoff of the left subclavian artery

- Position should be confirmed by fluoroscopy or chest x-ray

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

58

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

Inserting the Balloon catheter

- Many vascular complications occur during insertion itself

- Resistance during insertion either indicates PVOD or dissection

- Kinking of IABP raquo improper inflationdeflation

30

- The end of the balloon should be just distal (1-2 cm) to the takeoff of the left subclavian artery

- Position should be confirmed by fluoroscopy or chest x-ray

31

Connecting to console - Connect helium gas tube to the console via a long extender - Open helium tank

- The central lumen of the catheter is flushed and connected to pressure

tubing with 3 way and then to a pressure transducer to allow for monitoring of central aortic pressure

- Zero the transducer

Initial set-up- Once connected properly the console would show ECG and pressure waveforms- Check Basal mean pressure- Make sure the setting is at ldquoautordquo- Usually IABP started at 11 or 12 augmentation- Usually Augmentation is kept at maxim

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

62

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

58

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

62

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

58

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

62

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

58

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

62

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

58

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

bull Insert the balloon only over the guide wire

bull Hold the catheter close to skin insertion point

bull Advance in small steps of 1 to 2 cm at a time and stop if any resistance

bull The IABP should advance freely

Inserting the Balloon catheter

- Many vascular complications occur during insertion itself

- Resistance during insertion either indicates PVOD or dissection

- Kinking of IABP raquo improper inflationdeflation

30

- The end of the balloon should be just distal (1-2 cm) to the takeoff of the left subclavian artery

- Position should be confirmed by fluoroscopy or chest x-ray

Positioning

31

Connecting to console - Connect helium gas tube to the console via a long extender - Open helium tank

- The central lumen of the catheter is flushed and connected to pressure

tubing with 3 way and then to a pressure transducer to allow for monitoring of central aortic pressure

- Zero the transducer

Initial set-up- Once connected properly the console would show ECG and pressure waveforms- Check Basal mean pressure- Make sure the setting is at ldquoautordquo- Usually IABP started at 11 or 12 augmentation- Usually Augmentation is kept at maxim

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

62

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

62

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

- due to a loose connection- a leak in the IAB catheter- H2O condensation in the external tubing- a patient who is tachycardiac and febrile which causes increased gas diffusion through the IAB membrane

58

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Patient Management During IABP support

63

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

Catheter Kink

Rounded balloon pressure waveform- Loss of plateau resulting from a kink or obstruction of shuttle gas

- Kink in the catheter tubing- Improper IAB catheter position- Sheath not being pulled back to allow inflation of the IAB- IAB is too large for the aorta- IAB is not fully unwrapped- H2O condensation in the external tubing

Patient Management During IABP support

Anticoagulation-- maintain apTT at 50 to 70 seconds

CXR daily ndash to RO IAB migration

Check lower limb pulses - 2 hourly - If not palpable raquo - vascular obstruction - thrombus embolus or dissection (urgent surgical consultation)

Prophylactic antibiotics --

Hip flexion is restricted and the head of the bed should not be elevated beyond 30deg

61

Never leave in standby by mode for more than 20 minutes gt thrombus formation

Dailyndash Haemoglobin (risk of bleeding or haemolysis)ndash Platelet count (risk of thrombocytopenia) ndash Renal function (risk of acute kidney injury secondary to distal

migration of IABP catheter)

Wean off the IABP as early as possible as longer duration is associated with higher incidence of limb complications

Weaning of IABP

Timing of weaning

- Patient should be stable for 12 ndash 24 hours - Decrease inotropic support - Decrease pump ratio

ndash From 11 to 12 or 13 - Decrease augmentation - Monitor patient closely

ndash If patient becomes unstable weaning should be immediately discontinued

64

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved

IABP Removal

- Discontinue heparin six hours prior to removal

- Disconnect the IAB catheter from the IAB pump

- Patient blood pressure will collapse the balloon membrane for withdrawal

- Withdraw the IAB catheter through the introducer sheath until resistance is met- NEVER attempt to withdraw the balloon membrane through the introducer sheath- Remove the IAB catheter and the introducer sheath as a unit

- Check for adequacy of limb perfusion after hemostasis is achieved
