A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally-invasive procedure performed during resuscitation of critically-injured trauma patients. Originally developed as a less invasive alternative to emergency thoracotomy with aortic cross clamping, REBOA is performed to gain rapid control of non-compressible truncal or ...
A Foley catheter can also be used to ripen the cervix during induction of labor. When used for this purpose, the procedure is called extra-amniotic saline infusion . [ 9 ] In this procedure, the balloon is inserted behind the cervical wall and inflated, for example with 30-80 mL of saline. [ 9 ]
Diagram of a Foley catheter. Foley first described the use of a self-retaining balloon catheter in 1929, to be used to achieve hemostasis after cystoscopic prostatectomy. [2] He worked on development of this design for use as an indwelling urinary catheter, to provide continuous drainage of the bladder, in the 1930s.
The intra-aortic balloon pump (IABP) is a mechanical device that increases myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction. It consists of a cylindrical polyurethane balloon that sits in the aorta , approximately 2 centimeters (0.79 in) from the left subclavian artery . [ 1 ]
In anaesthesia and advanced airway management, rapid sequence induction (RSI) – also referred to as rapid sequence intubation or as rapid sequence induction and intubation (RSII) or as crash induction [1] – is a special process for endotracheal intubation that is used where the patient is at a high risk of pulmonary aspiration.
Symptoms usually present in individuals with severe aortic stenosis, though they may also occur in those with mild to moderate aortic stenosis. The three main symptoms of aortic stenosis are loss of consciousness , anginal chest pain and shortness of breath with activity or other symptoms of heart failure such as shortness of breath while lying ...
Levine's sign is a clenched fist held over the chest to describe ischemic chest pain. [1]It is named for Samuel A. Levine (1891–1966), an influential American cardiologist, who first observed that many patients with chest pain made this same sign to describe their symptoms.
