May also penetrate into the submucosa and cause significant gi bleeding. Physiologically stressful situations that lead to srmd include sepsis, organ failure, prolonged mechanical ventilation, thermal injury, and surgery. Critical care patients with the specific characteristics listed above are at highest risk. 9 zollinger–ellison syndrome zollinger–ellison syndrome (zes) is caused by a gastrin-producing tumor called a gastrinoma. The resulting gastric acid hypersecretion causes diarrhea and malabsorption. Ulcers tend to be numerous and have a high risk of perforation and bleeding. 10 treatments include surgical resection when feasible and highdose oral proton pump inhibitor (ppi) therapy. Other causative factors cigarette smoking is associated with a higher prevalence of ulcers in h. Pylori-infected patients. 2 the detrimental effects of smoking on the gastric mucosa may involve increased pepsin secretion, duodenogastric reflux of bile salts, elevated levels of free radicals, and reduced prostaglandin-2 (pg2) production, resulting in decreased mucus and bicarbonate secretion. 11 although psychosocial factors such as life stress, personality patterns, and depression may influence pud prevalence, a clear causal relationship has not been demonstrated.

Case study 10 the final patient is a 23-year-old woman who was admitted 6 hours ago for diabetic ketoacidosis. With appropriate therapy, her hyperglycemia has improved and her serum ketones are clearing. Because she continues to feel poorly, repeat blood work is obtained. Studies show a ph of 7. 15, a paco2 of 15 mm hg (2. 0 kpa), an hco3 – of 5 meq/l (5 mmol/l), a sodium concentration of 140 meq/l (140 mmol/l), and a chloride level of 110 meq/l (110 mmol/l). What is the primary acid–base disorder?. Is there a mixed disorder?. Given the clinical history, what is the most likely explanation for the abg findings?. Clinically acceptable range. This agent results in gradual changes in the serum hco−3  and is not used to acutely correct a patient’s acid– base status. If alkalosis is profound and potentially life threatening (due to seizures or ventricular tachyarrhythmias), hemodialysis or transient hcl infusion can be considered. The hydrogen ion deficit (in milliequivalents or millimoles) can be estimated from the current bicarbonate concentration (hco−3 curr), the desired bicarbonate concentration (hco−3 post), and the body weight (in kilograms) as follows. H+ deficit = 0. 4 × weight × (hco−3 curr – hco−3 post) after estimating the h+ deficit, 0. 1 to 0. 2 n hydrochloric acid (hcl) is infused at 20 to 50 meq/hour (20–50 mmol/hour) into a central vein. Arterial ph must be monitored at least hourly and the infusion stopped as soon as clinically feasible. Ammonium chloride and arginine hydrochloride, agents that result in the formation of hcl, are not commonly prescribed because they may lead to significant toxicity. Ammonium chloride may cause accumulation of ammonia leading to encephalopathy while arginine 448  section 4  |  renal disorders table 28–5  table 28–6  common causes of metabolic alkalosis common causes of respiratory acidosis urine cl– < 10 meq/l (10 mmol/l) urine cl– > 10 meq/l (10 mmol/l) alkali administration   iv bicarbonate therapy   oral alkali therapy parenteral nutrition with acetate “contraction alkalosis” postdiuretic use decreased chloride intake loss of gastric acid  vomiting   nasogastric suction posthypercapnia villous adenomas (some) drugsa   corticosteroid therapy  diuretics hypokalemia mineralocorticoid excess  hyperaldosteronism   bartter syndrome   cushing syndrome cns disease   brainstem lesions   central sleep apnea  infection   intracranial hypertension  trauma  tumor  vascular drugsa  aminoglycosides  anesthetics  β-blockers   botulism toxin  hypnotics  narcotics  neuromuscular blocking agents  organophosphates  sedatives neuromuscular disease   guillain-barré syndrome   muscular dystrophy   myasthenia gravis  polymyositis pulmonary disease   lower airway obstruction  chronic obstructive pulmonary disease   foreign body   status asthmaticus may be observed with therapeutic doses or overdoses. A hydrochloride can induce life-threatening hyperkalemia through unclear mechanisms. Respiratory acidosis respiratory acidosis is characterized by a reduced arterial ph, a primary increase in the arterial paco2 and, when present for sufficient time, a compensatory rise in the hco−3  concentration. Because increased co2 is a potent respiratory stimulus, respiratory acidosis represents ventilatory failure or impaired central control of ventilation as opposed to an increase in co2 production.

Although an association with vitamin d deficiency is uncommon, an assessment of both maternal and neonatal serum 25(0h)d level may be warranted.
