The role of prophylactic intra-aortic balloon pump counterpulsation (IABP) in emergency non-cardiac surgery.

Patients with recent myocardial infarction (MI), congestive heart failure, severe angina, or uncorrected multivessel coronary artery disease are at increased risk of cardiac complications after urgent major non-cardiac surgery. Although invasive haemodynamic monitoring and preoperative optimization of cardiac status may lead to some reduction in the rate of perioperative cardiac events, the mortality from such events still remains high. The use of an intra-aortic balloon pump (IABP) may play a role in such patients by improving the function of the injured heart. We report our experience with the use of perioperative IABP in a patient with unstable angina and recent MI who underwent urgent cholecystectomy. There were no perioperative cardiac events while the IABP was in place. The anaesthetic concerns, intraoperative and postoperative monitoring and care and usefulness of IABP will be discussed.

[Liver circulation during acute cardiac insufficiency and the use of intra-aortic balloon counterpulsation].

Liver hemodynamics was experimentally studied in a model of acute heart failure caused by successive ligation of coronary artery branches and the following cardiogenic shock and during assisted circulation using intraaortic balloon contrapulsation. It has been established that intraaortic balloon contrapulsation promotes to the elimination of hemodynamic liver disturbances, however no final recovery of the organ hemodynamics was observed after 2 hours of contrapulsation. The method of intraaortic balloon contrapulsation is recommended at early stages of acute heart failure prior to the onset of profound ischemic changes in the liver.

Percutaneous cardiopulmonary bypass and innovations in clinical counterpulsation.

This report points out the progress that has been made with cardiac support devices since they were first clinically applied in the mid-1960s. Advances in technology have allowed the development of PBY. Innovatively applied modifications of existing support systems have allowed patient survival when conventional systems could not be utilized. Continued refinements in design, materials, and power sources will allow circulatory assistance to progress as an extremely useful clinical tool for the treatment of patients with acute and chronic ventricular failure.

Abdominal binding and counterpulsation in cardiopulmonary resuscitation.

During the past 15 years, many different studies have documented improved blood pressure and blood flow above the diaphragm when some type of abdominal compression was added to conventional CPR, either in animals or in humans. Rhythmically interposed abdominal compressions seem to provide even greater hemodynamic benefit than continuous abdominal binding. Both total flow and the distribution of flow to vital organs above the diaphragm are improved, while the chances of liver entrapment and damage during chest compression are reduced. The technique of interposed abdominal compression can be performed with the bare hands of a second or third rescuer. It requires no special equipment, and could be easily incorporated into existing training programs for basic rescuers. In this sense the technique may constitute a logical evolution in basic life support, if subsequent clinical research confirms that it improves outcome.
