transient increase in end tidal carbon dioxide [ Time Frame: 4-12 seconds ]
Once sodium bicarbonate is injected the measured end-tidal carbon dioxide will transiently increase by at least 10% of baseline

  • Change in venous blood pH [ Time Frame: 10-20 minutes ]
    Blood pH and will be measured prior and ten minutes after the injections
  • Subjective adverse symptoms associated with injection of sodium bicarbonate [ Time Frame: 1 minute ]
    The subjective symptoms as well as hemodynamic changes associated with the injection of sodium bicarbonate will be recorded
  • change in venous blood sodium [ Time Frame: 10- 20 minutes ]
    blood sodium level will be measured before and 10-20 minutes after the end of the injections.
  • change in venous blood bicarbonate level [ Time Frame: 10-20 minutes ]
    blood level of bicarbonate will be measured before and 10-20 minutes after the injection.

Intravenous Sodium Bicarbonate Verifies Intravenous Position of Catheters in Spontaneously Breathing Adult Volunteers
Intravenous Sodium Bicarbonate Verifies Intravenous Position of Catheters in Spontaneously Breathing Adult Volunteers

Vascular access in patients carries a significant risk of accidental extravasation of intravenous (IV) fluids and medications with the potential for tissue injury. This prospective controlled study assessed the diagnostic utility of using intravenous diluted sodium bicarbonate to confirm placement of IV catheters in volunteers . Diluted sodium bicarbonate or 0.9% normal saline, will be injected in a randomized order while end-tidal carbon dioxide in the exhaled air will be monitored. The investigators hypothesize that the injected bicarbonate will dissolve into carbon dioxide and water and cause a transient increase in the measured exhaled CO2.

The effect is unique to bicarbonate and will not appear once normal saline is injected. the safety of the administration of bicarbonate on the metabolic profile of the volunteers will be assessed by measurement of venous blood pH and electrolytes.

The investigators hypothesize that the injected bicarbonate will dissolve into carbon dioxide and water and cause a transient increase in the measured exhaled CO2. Arbitrary increase of more than 10%in end-tidal carbon dioxide is considered as a positive response.
