Hypovolemia

Hypovolaemia


Presentation

  • A 50-year-old man presented with a 1-year history of paroxysmal ataxia of gait and short attacks of blurred vision when he stood up from a recumbent position and began to walk. Orthostatic headache was not a feature of his clinical presentation.[ncbi.nlm.nih.gov]
  • This review presents specific situations that are common in daily clinical practice and require targeted infusate therapy in patients with reduced volume status.[ncbi.nlm.nih.gov]
  • Data are presented as mean SE. PPI underwent log transformation and is presented as median (25th-75th). Of the 25 subjects, one did not complete the study because of cardiovascular collapse.[ncbi.nlm.nih.gov]
  • The medical problems presented by an 83-yr-old man with hepatic amyloidosis complicated by massive ascites and a right hydrothorax are described.[ncbi.nlm.nih.gov]
  • We discuss possible explanations and present evidence that the pulmonary capillary wedge pressure does not always accurately reflect volume status.[ncbi.nlm.nih.gov]
Anemia
  • In the laboratory tests minimal normocytic anemia, mild leukopenia, polyclonal hypergammaglobulinemia and antinuclear antibodies (ANA), anti-double-stranded DNA antibodies (dsDNA), antibodies against extractable nuclear antigens (ENA) type SSA-Ro, anti-Smith[ncbi.nlm.nih.gov]

  • Each may have a subtle initial presentation of restlessness, tachycardia, and pallor with a sense of impending doom/anxiety but with further mechanism of injury clarified and assessment usually clarifies the situation before a catastrophic event occurs[allnurses.com]
  • And that's actually known as conjunctival pallor. Paleness of the conjunctiva. Okay, so what do we do to diagnose and treat this? The diagnosis you're going to use your different shock labs. Of course serum lactate and ABG to assess oxygenation.[khanacademy.org]
  • These include: Excessive bleeding Sweating Vomiting Diarrhea Donating blood Hypovolemia Signs and Symptoms The symptoms of decreased blood volume include: Pallor of skin Pale skin is one of the main symptoms of lowered blood volume.[hxbenefit.com]
Hypotension
  • Although hypovolemia may intuitively seem a likely cause for hypotension in intensive care patients, its role in the pathogenesis of intradialytic hypotension may be overestimated.[ncbi.nlm.nih.gov]
  • Non-hypotensive hypovolemia, observed during mild haemorrhage or blood donation leads to reflex readjustment of the cardiac autonomic tone.[ncbi.nlm.nih.gov]

Tachycardia
  • Class I hemorrhage (loss of 0-15%) In the absence of complications, only minimal tachycardia is seen. Usually, no changes in BP, pulse pressure, or respiratory rate occur.[emedicine.medscape.com]
  • One of the signs and symptoms of hypovolemia is tachycardia (Nursing, 2000). Tachycardia is the medical term for rapid heartbeat (Mayo Clinic).[brighthub.com]
  • Tachycardia is sensitive but not specific indicator. Prolonged capillary refill ( 2 seconds) , especially when combined with tachycardia, is more specific, although it may be difficult to measure. Cold skin and decreased urine output may be present.[openanesthesia.org]
  • Usually chest pain and tachycardia are also present. Hypovolemia is insufficient amounts of intravascular fluid. Symptoms can be tachycardia, tachypnea, low blood pressure, poor perfusion, slow cap refill, and signs of dehydration.[allnurses.com]
  • Fluid resuscitation with crystalloid (Saline solution or Lactated Ringer's solution) and blood transfusion are usually necessary. * Systolic blood pressure falls to 100mmHg or less * Classic signs of hypovolemic shock * Marked tachycardia 120 bpm (heart[sphynxcatvp.nocturna.org]

Narrow Pulse Pressure
  • A narrow pulse pressure in a hypovolemic shock patient indicates a decreasing cardiac output and an increasing peripheral vascular resistance.[ems1.com]
  • Class IV hemorrhage (loss of 40%) Symptoms include the following: marked tachycardia, decreased systolic BP, narrowed pulse pressure (or immeasurable diastolic pressure), markedly decreased (or no) urinary output, depressed mental status (or loss of consciousness[emedicine.medscape.com]
  • These circulation changes include tachycardia, narrowing pulse pressure, possible systolic hypotension, capillary refill time 2 seconds, cool/pale skin, weak to absent peripheral pulses, reduced urine output.[acls-algorithms.com]

Blurred Vision
  • A 50-year-old man presented with a 1-year history of paroxysmal ataxia of gait and short attacks of blurred vision when he stood up from a recumbent position and began to walk. Orthostatic headache was not a feature of his clinical presentation.[ncbi.nlm.nih.gov]

  • Postoperative organ dysfunction severely affects the prognosis of surgical patients. Despite several trials evaluating restrictive or liberal fluid strategies, the ideal fluid replacement strategy remains controversial.[clinicaltrials.gov]
  • Elderly have a poor prognosis compared to young adults.[howshealth.com]
  • Once they appear, you know the prognosis is poor unless you act quickly. Meet your patients Knowing which patients are at risk can be tricky -- hypovolemic shock can occur for so many reasons.[163.178.103.176]

Etiology

  • We should always take the etiology of CSF hypovolemia into consideration, and especially pay attention in patients with pneumocephalus and subdural fluid collection alongside brain sag on computed tomography.[ncbi.nlm.nih.gov]

  • The pathophysiology of orthostatic hypertension has not been elucidated. It is believed it involves activation of the sympathetic nervous system [1], vascular adrenergic hypersensitivity and diabetic neuropathy [2].[biology.stackexchange.com]

Prevention

  • HUT was performed without ELC (control model), with ELC inflated before HUT (prevention model) and after HUT (restore model). The decrease in stroke volume (SV) during the prevention model versus control model was 17 3% versus 27 3%.[ncbi.nlm.nih.gov]
  • The analysis of these curves can be used to re-assess "dry" weights, prevent intradialytic hypovolemia and decrease the use of antihypertensive agents.[ncbi.nlm.nih.gov]
  • This should allow timely intervention and prevent the development of symptomatic cerebral hypoperfusion.[ncbi.nlm.nih.gov]
  • In all 3 cases of chronic subdural hematoma, its recurrence was prevented. In 1 patient, the orthostatic headache disappeared completely, and it was relieved in the other 4 patients.[ncbi.nlm.nih.gov]
  • These observations may help preventing pulmonary fluid overloading.[ncbi.nlm.nih.gov]
