The Trendelenburg position is used in surgery, especially of the abdomen and genitourinary system. It allows better access to the pelvic organs as gravity pulls the intra-abdominal organs away from the pelvis. Evidence does not support its use in hypovolaemic shock, with concerns for negative effects on the lungs and brain. [2]
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 ...
Skin grafting is a surgical procedure where a piece of healthy skin, also known as the donor site, is taken from one body part and transplanted to another, often to cover damaged or missing skin. [12] Before surgery, the location of the donor site would be determined, and patients would undergo anesthesia. [13]
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 ...
In addition, "pharyngo" means pharynx, "laryngo" means larynx, "esophag" means esophagus. Thus, "pharyngolaryngoesophagectomy" refers to the surgical removal of the three. The field of minimally invasive surgery has spawned another set of words, such as arthroscopic or laparoscopic surgery. These take the same form as above; an arthroscope is a ...
Sometimes leakage of fluid from the cervical opening can be seen when the person coughs or performs a valsalva maneuver. [ 9 ] Nitrazine test: A sterile cotton swab is used to collect fluid from the vagina and place it on nitrazine (phenaphthazine) paper.
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.
The eyelids and surrounding skin are swabbed with a disinfectant, such as 10% povidone-iodine, and topical povidone-iodine is put in the eye. The face is covered with a cloth or sheet with an opening for the operative eye. The eyelid is held open with a speculum to minimize blinking during surgery. [3]
