Arterial blood gases and some blood parameters in Tetralogy of Fallot patients

Abstract EN

The present study was done to assess the effect of the tetralogy of Fallot (TOF) on some arterial blood measurements including pH, the partial pressure of carbon dioxide (PaCO2), the partial pressure of oxygen (PaO2), Base excess (BE), Red blood cells (RBC), Packed cell volume (PCV), and Hemoglobin (Hb) concentration in the Erbil City of Iraq.

For this purpose 80 (40 males and 40 females) patients with (TOF) and aged between 3-33 years were used in this study.

This retrospective cohort study was conducted from March /2018 to October 2020 and carried out in the Surgeries Hospital Specialist - Cardiac Center in Erbil city.

The studied parameters were estimated before and two to three weeks after postoperative correction of TOF.

A dependent t- test was used for data analysis.

The results showed that males and females with (TOF) after surgical correction have significantly p≤ 0.001 lower PaCO2, RBC, PCV, and Hb concentration, while the concentration of PaO2 and the value of BE were significantly p≤ 0.001 higher after surgical correction in comparison with the value before surgery.

Moreover, males showed a significantly higher concentration of RBC, PCV, and hemoglobin than females after surgical correction.

Conclusions: Surgery repair of (TOF) restore the arterial blood measurements PaCO2, PaO2, BE, RBC, PCV, and Hb concentration to the normal value in males and females.
