A review of the causes of postoperative hypoxia.
نویسنده
چکیده
ARTERIAL OXYCEN TENSIONS are reduced in the postoperative patient breathing air. This was studied by Gordh in 19581 and by Nunn and Payne in 1962 -0 and was found to occur, despite normal ventilatory volumes and arterial carbon dioxide tensions, in patients whose preoperative cardiorespiratory status was normal. The purpose of this review is to outline the physiological components and discuss the aetiological factors that may be important in a decreased postoperative Po2. The extent of the decreased arterial oxygen tension varied in different studies with the time of sampling and other conditions as shown in Table I. z-7 TABLE I EXAMPLES OF POSTOPERATIVE PO2 IN PATIENTS BREATHING AIR

Human activated macrophages and hypoxia: a comprehensive review of the literature
Macrophages accumulate in poorly vascularised and hypoxic sites including solid tumours, wounds and sites of infection and inflammation where they can be exposed to low levels of oxygen for long periods. Up to date, different studies have shown that a number of transcription factors are activated by hypoxia which in turn activate a broad array of mitogenic, pro-invasive, pro-angiogenic, and pro...
متن کاملPhysiological role of adenosine and its receptors in tissue hypoxia-induced
It is well known that the metabolic factors play an important role in the regulation of angiogenesis. Increased metabolic activity leads to decreased oxygen levels and causes tissue hypoxia. Hypoxia starts different signals to stimulate angiogenesis and promotes oxygen delivery to tissues. It has been suggested that released adenosine from hypoxic tissues plays a vital role in angiogenesis. ...

Background: Brown-Sequard syndrome (BSS) is a rare neurological condition resulting from a hemisection injury to or unilateral compression on the spinal cord. The most common causes of BSS that are amenable to be treated surgically can be divided into traumatic and non-traumatic injuries. Traumatic injuries are often reported as the main cause of BSS. However, non-traumatic injuries of the spin...
متن کاملBlockade of Hypoxia: The Impact on Tumor Growth in an Experimental Tumor Model
Background: Tumor microenvironment is an active factor participating in immunoregulation, thereby preventing immunosurveillance and limiting the efficacy of anticancer therapies. Hypoxia as a major characteristic of solid tumors causes the expression of Hypoxia-Inducible Factor-1α (HIF-1α). This is a transcription factor that mediates hypoxic responses of tumor cells and involves in the express...
متن کاملA Review of the Effects of Various Venotonics on Improvement of Postoperative Symptoms
There are evidences on the efficacy of several venotonics in improving postoperative symptoms, including bleeding, pain, etc. A thorough search was conducted in Google Scholar, PubMed, and Cochrane Library covering the articles published in 2000–2020. We included trials assessing the efficacy of phlebotonics in patients with chronic venous insufficiency and other venous diseases or traumas. Fin...
