Eficacia de la detección percutánea de oxígeno como guía terapéutico-quirúrgica en lesionados medulares con úlceras por presión crónicas: Estudio preliminar

Abstract

In this clinical study the detection of transcutaneous oxygen has been performed (TcpO2) to 11 consecutive patients with spinal cord injury chronic paraplegics (more than 1 year of evolution) with chronic pressure ulcers grade IV (more than 6 months). In all patients were analyzed preoperative and postoperative TcpO2 values, with the following results. In the pre-operative position 1 (P1-pre: to 1 cm of the ulcer edge) values obtained are of 27.28 ± 13.83 mm Hg, while in P1 postoperative were 34.96 ± 19.06 (p <0.05). The average value of the reference electrode (no 1) preoperative (51.63 ± 12.53 mm Hg) is statistically significant (p <0.05) when compared with the value obtained with the electrode no1 (38.60 ± 14, 63 mmHg) in the postoperative state. The average value of the reference electrode (no 1) preoperative (50.07 ± 13.54 mm Hg) is statistically significant (p <0.05) when compared with the average values of the positions (P1, P2, P3) obtained of TcPO2 electrode no 2 (29.17 ± 15.03 mm Hg), no 3 (34.51 ± 13.15 mm Hg) and no 4 (30.37 ± 17.81 mm Hg) analyzed preoperatively. With these findings, we demonstrate hypoxemic levels to 1 cm of chronic pressure ulcers edge grade IV and postoperative progress. Thus, the technique of transcutaneous oxygen detection can be considered as a therapeutic guide in the detection and monitoring of pressure ulcers treatment with the possibility of establish therapeutic interventions to improve the oxygen levels detected in them.
