Abstract

Background and aims

Ventilatory function may be impaired in postoperative hospitalized patients due to anesthesia, pain, and prolonged bed rest. Such alterations impact metabolic and muscular homeostasis. Blood lactate and muscle oximetry are key indicators of tissue oxygenation, while the Kinesiological Ventilatory Workload Index (IKCTV) provides an objective assessment of respiratory effort. This study aimed to determine the relationship between ventilatory workload, blood lactate levels, and muscle oximetry in adults hospitalized after digestive or thoracic surgery.

Material and methods

Exploratory study including 42 adult patients in Valdivia, Chile. IKCTV, blood lactate (Accutrend Plus®), muscle oximetry (Moxy®), clinical parameters, and body composition were assessed. Spearman correlation coefficients were calculated and Wilcoxon tests for supine-standing differences were performed.

Results

Median age was 56 years and 81% of the participants underwent digestive surgeries. Ventilatory workload was mild in 32 patients and moderate in 10. Lactate correlated positively with IKCTV (rho = 0.443; P = .003) and with heart rate variation from supine to standing (rho = 0.341; P = .031). Muscle oximetry was not associated with IKCTV but correlated negatively with bed rest days (rho = −0.556; P < .001). Muscle mass showed inverse associations with glycemia and hemodynamic changes.

Conclusions

Integrating ventilatory workload, lactate, and muscle oximetry provides a novel approach to monitoring postoperative patients. These complementary measures may enhance functional and metabolic evaluation in the hospital setting.

住院术后患者呼吸、乳酸和肌肉氧合之间的关联：一项探索性研究

背景和目的术后住院患者的呼吸功能可能因麻醉、疼痛和长时间卧床而受损。这种改变影响代谢和肌肉稳态。血乳酸和肌肉氧饱和度是组织氧合的关键指标，而运动通气负荷指数（IKCTV）提供了呼吸功的客观评估。本研究旨在确定消化或胸外科手术后住院的成人通气工作量、血乳酸水平和肌肉血氧饱和度之间的关系。材料与方法在智利瓦尔迪维亚进行了一项包括42名成年患者的探索性研究。评估IKCTV、血乳酸（Accutrend Plus®）、肌氧饱和度（Moxy®）、临床参数和体成分。计算Spearman相关系数，并进行仰卧-站立差异的Wilcoxon检验。结果中位年龄为56岁，81%的参与者接受了消化手术。32例患者呼吸负荷为轻度，10例为中度。乳酸与IKCTV呈正相关（rho = 0.443; P = 0.003），与仰卧位到站立位心率变化呈正相关（rho = 0.341; P = 0.031）。肌氧饱和度与IKCTV无相关性，但与卧床休息天数呈负相关（rho = - 0.556; P < .001）。肌肉质量与血糖和血流动力学变化呈负相关。结论综合通气负荷、乳酸和肌肉血氧测量为术后患者监测提供了一种新的方法。这些补充措施可以增强医院环境中的功能和代谢评估。
