PEMERIKSAAN RETRAKSI BEKUAN

Summary

This video demonstrates a laboratory procedure for observing blood clot retraction. The process starts with extracting blood and placing it in a tube, then waiting for an hour while monitoring the retraction of the clot. After one hour, the clot is carefully examined on a Petri dish for its consistency, which is found to be elastic. The results are compared by calculating the clot retraction percentage, with the final outcome being 26.6%. This procedure helps in understanding the blood clotting mechanism in patients.

Takeaways

• 😀 Blood sample is collected and placed into a tube for analysis.
• 😀 The sample undergoes retraction, which is then observed through the wall of the tube.
• 😀 The sample is allowed to rest for one hour to observe the clotting process.
• 😀 After one hour, the blood clot is carefully lifted and placed on a petri dish for inspection.
• 😀 The consistency of the clot is checked, and it is noted to be elastic.
• 😀 The clot's reaction is compared by measuring the volume difference between the original blood and the blood clot.
• 😀 The volume of the retracted clot is calculated by comparing it to the initial blood volume.
• 😀 For the specific case, the retracted clot volume is found to be 0.8 mL.
• 😀 The initial blood volume used for the sample is 3 mL.
• 😀 The retraction percentage is calculated as 26.67%, which is determined by dividing 0.8 mL by 3 mL and multiplying by 100.

Q & A

What is the first step in the procedure described in the transcript?

The first step is to take a sample from the patient, which is then placed into a tube.

What is done after the blood is placed into the tube?

After the blood is placed into the tube, it is subjected to retraction.

How long should the sample be left for after pouring it into the tube?

The sample should be left for one hour after being poured into the tube.

What is done after the one-hour wait?

After one hour, the blood clot is carefully lifted and placed in a petri dish.

What is observed once the blood clot is placed on the petri dish?

The consistency of the clot is observed, and in this case, it is described as being elastic.

What is compared during the reaction test?

The formation of the clot (after the blood clot is removed) is compared with the initial blood volume.

What is the volume of the clot retraction observed in this case?

The clot retraction observed in this case is 0.8 milliliters.

How is the percentage of clot retraction calculated?

The percentage of clot retraction is calculated by dividing the retraction volume (0.8 milliliters) by the initial blood volume (3 milliliters), then multiplying by 100%.

What is the result of the clot retraction calculation in this case?

The result of the clot retraction calculation is 26.67%.

What is the final action described in the transcript after the clot retraction calculation?

The final action is the mention of the pause, indicating a break in the procedure or observation.
