Evaluation of Blood Sampling From a Pre-existed Peripheral Intravenous Catheter Line

Study Overview
=================
Brief Summary
-----------------
Background: Peripheral Intravenous catheter (PIVC) is a frequently used device for intravascular access. It is usually indicated to administer intravenous fluid and medications. However, the investigators could possibly utilize this line for blood sampling even after using it as a fluid port.

Detailed Description
-----------------
Aims: To investigate the quality of previously flushed PIVC sample and the effectiveness of the withdrawal technique. Methodology: Study will be held in King Fahad University Hospital during a year after obtaining the IRB approval. Selection of study participants will be depending on their health status and the investigators will exclude pediatric participants. Two blood samples will be collected from participants. First one is after the insertion of the intravenous peripheral line. The second is after fluid infusion through the same line. Samples will be sent to the laboratory then. Results will be collected and analyzed. The importance of the research: If this type of sampling can be standardized , this means there will be less insertions to the patients, less adverse effects in relation to the number of insertions, fast and preexisted intravascular access for sampling so the time can be saved in critical conditions.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Comparison of pCO2, pO2 (mmHg) Before and After IV Fluid Infusion in Healthy Adults | Blood samples will be analyzed using a venous blood gas (VBG) machine to assess pCO2, pO2 (mmHg). We will measure these values both before and after IVF infusion. The comparison of results aims to detect any statistically significant changes. This approach prioritizes patient comfort by utilizing the same catheter and requiring only a minimal blood discard. | 1 year | 
| Comparison of PH Before and After IV Fluid Infusion in Healthy Adults | Blood samples will be analyzed using a venous blood gas (VBG) machine to assess PH. We will measure these values both before and after IVF infusion. The comparison of results aims to detect any statistically significant changes. This approach prioritizes patient comfort by utilizing the same catheter and requiring only a minimal blood discard. | 1 year | 
| Comparison of ctHb (g/dL) Before and After IV Fluid Infusion in Healthy Adults | Blood samples will be analyzed using a venous blood gas (VBG) machine to assess ctHb (g/dL) . We will measure these values both before and after IVF infusion. The comparison of results aims to detect any statistically significant changes. This approach prioritizes patient comfort by utilizing the same catheter and requiring only a minimal blood discard. | 1 year | 
| Comparison of SO2, FO2Hb, FCOHb, FMetHb (%) Before and After IV Fluid Infusion in Healthy Adults | Blood samples will be analyzed using a venous blood gas (VBG) machine to assess SO2, FO2Hb, FCOHb, FMetHb (%). We will measure these values both before and after IVF infusion. The comparison of results aims to detect any statistically significant changes. This approach prioritizes patient comfort by utilizing the same catheter and requiring only a minimal blood discard. | 1 year | 
| Comparison of cBase(Ecf)c, cHCO,-(P.st)c, cNa, cK, cCl, cCa (mmol/L) Before and After IV Fluid Infusion in Healthy Adults | Blood samples will be analyzed using a venous blood gas (VBG) machine to assess cBase(Ecf)c, cHCO,-(P.st)c, cNa, cK, cCl, cCa (mmol/L). We will measure these values both before and after IVF infusion. The comparison of results aims to detect any statistically significant changes. This approach prioritizes patient comfort by utilizing the same catheter and requiring only a minimal blood discard. | 1 year |
