Mean burst pressure for 9 suture anastomoses was 326 mm mercury. The highest pressure recorded when the anastomosis ruptured was taken to be the anastomotic burst pressure. The digital readout from the transducer accurately expressed the pressure on the anastomosis.
The catheter was tied into position with 6-0 suture, constructing a water-tight balloon of tissue inclusive of the repair site around the tubing, then attached via a "Y" adapter to a pressure transducer with a digital readout and to a saline filled syringe in an infusion pump. After 6 min of leak-free blood flow, the vessels were ligated and cannulated with PE 50 tubing. Rat femoral arteries underwent standard microsurgical anastomoses and sham surgeries. I have to take children's cough syrup because whatever they put in the adult varieties knocks me out and makes me jittery at the same time.An in vivo system was developed which allows researchers to determine the intraluminal pressures necessary to burst anastomosed blood vessels. I didn't think it was permanent, but it still made me feel better to hear it from the doctor. I went to the doctor and he said the vessels popped from the force of my coughing, and they would heal in a couple of days. I had coughed through most of the night, and when I got up the next morning, my left eye had about three popped blood vessels! It looked terrible, like I'd been in a fight or something. I had this happen when I had bronchitis the first time. I did my best with concealer when I went back to work, but I still looked like a zombie. I was so sick that the vomiting made capillaries in my face rupture, too. That happened to me the last time I had a stomach virus. The capillaries underneath her eyes - on her cheekbone will also pop, giving her skin a mottled or bruised look. Her migraines tend to make her very nauseated and the force of the vomiting causes the blood vessels in her eyes to pop. A co-worker gets these when she gets a migraine.
