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.
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 ]
Perhaps the most common indication for tracheal intubation is for the placement of a conduit through which nitrous oxide or volatile anesthetics may be administered. General anesthetic agents, opioids, and neuromuscular-blocking drugs may diminish or even abolish the respiratory drive.
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 typical presentation of takotsubo cardiomyopathy is chest pain with or without shortness of breath and associated electrocardiogram (ECG) changes mimicking a myocardial infarction of the anterior wall. During the course of evaluation of the patient, a bulging out of the left ventricular apex with a hypercontractile base of the left ...
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.
The balloon, when inflated, causes the catheter to "wedge" in a small pulmonary blood vessel. So wedged, the catheter can provide an indirect measurement of the pressure in the left atrium of the heart, showing a mean pressure, in addition to a, x, v, and y waves which have implications for status of the left atria and the mitral valve.
The area of the chest wall near the contusion may be tender [13] or painful due to associated chest wall injury. Signs and symptoms take time to develop, and as many as half of cases are asymptomatic at the initial presentation. [5] The more severe the injury, the more quickly symptoms become apparent.
