Summary
Objectives

This study was undertaken to evaluate whether the surgeons’ oxygen saturation of hemoglobin was affected by the surgical mask or not during major operations.

Methods

Repeated measures, longitudinal and prospective observational study was performed on 53 surgeons using a pulse oximeter pre and postoperatively.

Results

Our study revealed a decrease in the oxygen saturation of arterial pulsations (SpO2) and a slight increase in pulse rates compared to preoperative values in all surgeon groups. The decrease was more prominent in the surgeons aged over 35.

Conclusions

Considering our findings, pulse rates of the surgeon's increase and SpO2 decrease after the first hour. This early change in SpO2 may be either due to the facial mask or the operational stress. Since a very small decrease in saturation at this level, reflects a large decrease in PaO2, our findings may have a clinical value for the health workers and the surgeons.

Resumen
Objetivos

Este estudio se realizó para determinar si la saturación de oxígeno del cirujano se afectaba por el uso de la mascarilla, durante intervenciones de larga duración.

Métodos

Se hizo un estudio longitudinal y prospectivo en 53 cirujanos con medidas de la hemoglogina realizadas con un oxímetro para medir la saturación del pulso arterial. Se hicieron estudios antes y después de la operación.

Resultados

Nuestro estudio puso de manifiesto una disminución de la saturación de oxígeno de las pulsaciones arteriales (SpO2) y un ligero aumento de las pulsaciones en comparación con el estado preoperatorio en todos los grupos de cirujanos. La disminución era mayor en el grupo de edad superior a los 35 años.

Conclusiones

Según nuestros hallazgos, el ritmo del pulso aumenta y la concentración de SpO2 disminuye después de la primera hora de la operación. Este cambio temprano de SpO2 puede deberse a la mascarilla o al estrés de la intervención. Puesto que un ligero descenso en la saturación a este nivel refleja una mayor disminución de la PaO2, nuestros datos pueden tener un valor clínico para la salud del personal sanitario y para los cirujanos.
