This discharge may pass through the ganglia and the sympathetic trunk to the postganglia fibers arriving at the target organ, such as the vertebral artery and the blood vessels and subsequently induce hypertension. Among other things, high levels of ADH can cause cells to swell by altering the fluid-electrolyte balance, including sodium. I had really low pressure post op surgery too, but I lost little blood during the surgery (as it was minimally invasive fusion surgery). The administration of anesthesia causes dilation of blood vessels, which in turn, leads to a drop in the blood pressure levels. Low blood pressure has 3 main causes: decreased volume of blood, heart problems, and dilated blood vessels. The cervical decompressive surgery will be done with one of the following four operating methods: international standard anterior cervical discectomy and fusion (standard Smith-Robinson technique, intervertebral disc incised and removed to reduce pressure, interbody fusion by implanting cervical interbody fusion cage), anterior cervical corpectomy and fusion (cervical corpectomy decompression, interbody fusion by implanting titanium cage), posterior bilateral open-door decompression (modified Hemo anchored method) or one-side open door decompression (modified Hirobayashi anchored method). Therefore, a substantial number of patients with both hypertension and cervical spondylosis may benefit from this approach as the decrease in the quantity and/or dose of antihypertensive drugs would subsequently lead to fewer side effects from them. One of these risks is increased blood pressure. Background. Lancet. Treatment Primary outcome analyses will be carried out using analysis of covariance, as well as the first secondary endpoint.
