Anterior and posterior nostril blockage

1. After the nasal cavity is blocked, there is still blood flowing from the posterior nostril, and bleeding cannot be controlled. 2. After surgery for nasopharyngeal angiofibroma or nasopharyngeal carcinoma, the operation cavity is blocked and hemostasis. 3. In order to prevent the general anesthesia from descending the nasal cavity or sinus surgery, the blood flows into the lower respiratory tract, and the nasal nodule can be temporarily blocked during the operation. If the operation is finished without bleeding, the blocked yarn ball can be taken out. Treatment of diseases: nasopharyngeal carcinoma hemangioma Indication 1. After the nasal cavity is blocked, there is still blood flowing from the posterior nostril, and bleeding cannot be controlled. 2. After surgery for nasopharyngeal angiofibroma or nasopharyngeal carcinoma, the operation cavity is blocked and hemostasis. 3. In order to prevent the general anesthesia from descending the nasal cavity or sinus surgery, the blood flows into the lower respiratory tract, and the nasal nodule can be temporarily blocked during the operation. If the operation is finished without bleeding, the blocked yarn ball can be taken out. Preoperative preparation 1. Understand the bleeding situation, pay attention to the general condition, do a blood test and measure blood pressure, etc., in order to prevent hemorrhagic shock or collapse during surgery. 2. Prepare the blockage, usually with iodoform gauze or disinfected Vaseline gauze, the latter is a little longer and easy to smell, so it can be prepared by using dry gauze with antibiotic ointment or paraffin oil plus antibiotic solution. It is based on the principle that it is less irritating to tissues and has antiseptic and hemostasis effects. 3. The obstruction also needs a round pillow shape (about 3cm in length, 2.5cm in diameter) or a gauze ball that is blocked by the nose after the taper. Surgical procedure 1. Insert the anterior nostril of the catheter on the side of the occlusion, and pull it out of the oropharynx with a vascular clamp. The other end remains outside the anterior nares, and the two fixation lines of the posterior nostril are bound to the catheter. On the tube. 2. The left hand pushes the catheter outward, so that the yarn ball fixing line leads out the front nostril, and continues to pull out. The patient is opened, the assistant presses the tongue with the tongue depressor, and the operator holds the vascular clamp (or the finger). The ball is sent to the nasopharynx through the oropharynx, so that it is properly fixed to the posterior nostril. 3. The nasal cavity is blocked. 4. Place a small gauze roll in front of the nostrils, and fix the two fixed lines of the posterior nostril ball to the upper part. The lead at the back of the ball is taken out from the mouth and fixed on the cheek with a twisted cloth.
