Paracentesis is known to be a safe procedure when ascitic fluid is readily visible, so complications are typically rare. Possible complications following or during the procedure involve infection, bleeding, the leakage ascitic of fluid, or bowel perforation .
Intraperitoneal injection or IP injection is the injection of a substance into the peritoneum (body cavity). It is more often applied to non-human animals than to humans. In general, it is preferred when large amounts of blood replacement fluids are needed or when low blood pressure or other problems prevent the use of a suitable blood vessel for intravenous injection.
Patients with a high water permeability (UF-coefficient) of the peritoneal membrane can have an increased reabsorption rate of fluid from the peritoneum by the end of the dwell. The ability to exchange small solutes and fluid in-between the peritoneum and the plasma can be classified as high (fast), low (slow) or intermediate.
MasSpecPen. The MasSpec Pen is a mass spectrometry (MS) based cancer detection and diagnosis system that can be used for ex vivo [1] and in vivo [2] tissue sample analysis. The system collects biological molecules from a tissue sample surface via a solid-liquid extraction mechanism and transports the molecules to a mass spectrometer for analysis.
This procedure is performed when intra-abdominal bleeding (hemoperitoneum), usually secondary to trauma, is suspected. [2]In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for ...
The patient undergoing pericardiocentesis is positioned supine with the head of the bed raised between a 30- and 60-degree angle. This places the heart in proximity to the chest wall for easier insertion of the needle into the pericardial sac. [5] [7] For patients that are awake, a local anaesthetic is applied. [8]
Apart from bladder drainage, it also has various other uses for which it has not actually been designed, such as thoracostomy [3] and paracentesis. [ 4 ] The drain consists of a straight metal trocar, which serves as a core and guide for a plastic tube with a curved end that is kept straight while the trocar is inside.
Some practitioners prefer it for lumbar puncture in obese patients, where lying on their side would cause a scoliosis and unreliable anatomical landmarks. However, opening pressures are notoriously unreliable when measured in the seated position. Therefore, patients will ideally lie on their side if practitioners need to measure opening pressure.
