The Valsalva maneuver may help check for a dural tear following certain spinal operations, such as a microdiscectomy. An increase in intra-spinal pressure will cause cerebral spinal fluid (CSF) to leak out of the dura, causing a headache. [citation needed] The Valsalva maneuver has been associated with transient global amnesia. [17] [18] [19 ...
The Trendelenburg position may be used for drainage images during endoscopic retrograde cholangiopancreatography. [10] The Trendelenburg position is reasonable in those with a cord prolapse who are unable to achieve a knee-to-chest position. [11] It is a temporary measure until a cesarean section can be performed. [11]
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...

Thyroidectomy is the removal of all or part of the thyroid gland. Tonsillectomy is the removal of the tonsils. Trabeculectomy is the removal of part of the eye's trabecular meshwork as a treatment for glaucoma. Tumorectomy is the surgical removal of a tumor. Turbinectomy is the removal of the turbinate bones in the nasal passage.
In a Valsalva test, the patient is asked to pinch their nostrils together and open their mouth and then blow gently through the nose. The clinician must observe if there is passage of air or bubbling of blood in the post-extraction alveolus , as the trapped air from closed nostrils is forced into the mouth through an oroantral communication.
Both Valsalva maneuver and standing decrease venous return to the heart thereby decreasing left ventricular diastolic filling and causing more laxity on the chordae tendineae. This allows the mitral valve to prolapse earlier in systole , leading to an earlier systolic click (i.e. closer to S 1 ), and a longer murmur.
The lower teeth, and in particular the lower wisdom teeth, can therefore be in close proximity to this nerve. Damage to the inferior alveolar nerve is a risk of lower wisdom tooth removal (and other surgical procedures in the mandible). [20]
