ABSTRAKTWstęp: Terapeutyczne fale ciśnieniowe są często stosowane w leczeniu różnych schorzeń układu mięśniowo-szkieletowego, niemniej jednak efekt biologiczny ich odziaływania wciąż nie został w pełni poznany. W przedstawionych badaniach oceniono wpływ fal dźwiękowych o różnej sile bodźca stosowanych w terapii falą ultradźwiękową (ultrasound therapy – UST) i pozaustrojową radialną falą uderzeniową (radial extracorporeal shockwave therapy – rESWT) na wysycenie tlenem tkanki mięśniowej i temperaturę powierzchniową w kontekście potencjalnego efektu troficznego przy użyciu spektroskopii bliskiej podczerwieni (near-infrared spectroscopy).Materiały i metody: Badaniem objęto 41 zdrowych ochotników, w tym 27 poddanych UST i 14 rESWT, w wieku 22–48 lat. Pomiar saturacji tkankowej i temperatury powierzchni obszaru mięśnia podgrzebieniowego wykonano 4-krotnie: bezpośrednio przed (T0) i po (T1) oraz 15 (T2) i 30 min po aplikacji bodźca (T3). Saturacje mięśni zmierzono na 2 głębokościach: 20 mm (czujnik 1 – S1) i 12,5 mm (czujnik 2 – S2).Wyniki: Wartość regionalnej perfuzji tkankowej (rSO2 [%]) istotnie zmniejszyła się natychmiast oraz po 15 i 30 min od UST. Wartości początkowe, wynoszące 71,26 ±5,47% (S1) i 88,26 ±2,89% (S2) dla odpowiednich głębokości, znacząco spadły po bodźcowaniu odpowiednio do 68,89 ±5,26% (T2) i 68,93 ±5,12% (T3) na głębokości 20 mm i 86,63 ±5,37% (T1) i 86,52 ±3,38% (T2) na głębokości 12,5 mm.Wnioski: Uzyskane wyniki wskazują, że tylko leczenie za pomocą UST ma znaczący wpływ na zmiany oksymetrii regionalnej, co tłumaczy się ich działaniem przekrwiennym i termicznym w tkankach głębokich, które z kolei indukują dysocjacje tlenu z hemoglobiny do tkanek i efekt troficzny.

Public Health Importance

Shock in children remains public health importance and causes significant morbidity and mortality worldwide. Hypoperfusion in shock results in decreased oxygen delivery to the tissues, causing a shift from more efficient aerobic pathways to anaerobic metabolism, which results in lactate as the end product. Unlike blood lactate measurement, near-infrared spectroscopy (NIRS) monitoring system is safe and easy to use in measuring tissue oxygenation non-invasively. However, NIRS monitoring has yet to be validated against a standard measure of regional oxygenation. The primary objective of this article is to review the role of cerebral oxygen saturation (rSO2) measured by NIRS in evaluating the outcome of pediatric shock resuscitation.

Regional Oxygen Saturation

Up to now, it is still unknown whether microcirculation of deeper peripheral tissue (knee) can be modulated by acupuncture or acupressure on a meridian acupoint. The goal of this pilot study was to investigate possible effects of acupressure at the Xiyangguan acupoint (GB33) on the regional oxygen saturation of the deeper knee tissues by near-infrared spectroscopy (NIRS). Twelve healthy volunteers with a mean age of23.8±1.6years were investigated. Acupressure stimulation was performed for 5 minutes at the Xiyangguan acupoint. The results of the controlled study showed a significant increase of the values of regional oxygen saturation on the stimulated side of the knee (P=0.033), whereas the opposite side on the same knee showed insignificant changes. These results may serve as a valuable basis for monitoring a possible therapeutic effect (e.g., after Khalifa therapy) in patients with knee problems.

Objective: Venoarterial extracorporeal membrane oxygenation is an effective mechanical circulatory support that is used to rescue critically ill patients after congenital heart surgery. As there was still no recommended guideline for monitoring parameters during extracorporeal membrane oxygenation (ECMO), this study aimed to investigate the role of near-infrared spectroscopy (NIRS) in the early period of venoarterial (VA)-ECMO.Method: This study enrolled patients with NIRS monitoring during ECMO after pediatric cardiac surgery at Shanghai Children's Medical Center (2018–2020). The information obtained from the retrospective, the observational dataset included the demographic information, diagnoses, baseline characteristics, procedural details, ECMO data, monitoring data, in-hospital mortality, and complications of the patients.Results: The overall mortality rate was 43.6%. Lactate was significantly higher in non-survivors compared to survivors at 12 h (11.25 ± 7.26 vs. 6.96 ± 5.95 mmol/l, p = 0.022) and 48 h [2.2 (0.7, 20) vs. 1.4 (0.7, 5.8) mmol/l, p = 0.008] after initiation of ECMO. The cranial regional oxygen saturation (CrSO2) was significantly higher in survivors compared to non-survivors at 24 h (62.5 ± 14.61 vs. 52.05 ± 13.98%, p = 0.028), 36 h (64.04 ± 14.12 vs. 51.27 ± 15.65%, p = 0.005), and 48 h (65.32 ± 11.51 vs. 55.00 ± 14.18%, p = 0.008). Multivariate logistics regression analysis of the hemodynamic and laboratory parameters revealed that the CrSO2 at 36 h (OR = 0.945, p = 0.049) and 48 h (OR = 0.919, p = 0.032) was related to mortality. The use of continuous renal replacement therapy (OR = 14.940, p = 0.039) was also related to mortality. The optimal cutoff values for CrSO2 for predicting mortality after weaning off ECMO at 36 and 48 h were 57% (sensitivity: 61.5%, specificity: 80%) and 56% (sensitivity: 76.9%, specificity: 70%), respectively. The risk of mortality was higher among patients with a CrSO2(36h) < 57% (p = 0.028) by Kaplan-Meier analysis.Conclusion: Near-infrared spectroscopy may be a useful tool for monitoring the hemodynamic stability during the early period of ECMO, while CrSO2 can predict the in-hospital mortality after ECMO.
