摘要

Background and aims: Managing pain therapy plays a major role in postoperative care. Although blood pressure (BP) and heart rate (HR) are influenced by sympathetic activity, to evaluate a patient's condition, face-to-face contact and the patient's ability to communicate are inevitable. Recently, new approaches to monitor pain have been investigated. Skin conductance variation is based on sweat gland filling. For its evaluation, numbers of fluctuations (NFSC) and area under the curve (AUC) have been studied. The surgical pleth index (SPI) combines assessment of peripheral and cardiac sympathetic tone by taking into account amplitude and interval of the plethysmographic curve. The study aims to investigate feasibility and validity of NFSC and SPI in objective monitoring of postoperative recovery.Methods: Postoperative patients were treated and monitored according to internal hospital standards. Each 15 minutes, pain level was requested (NRS), BP, HR, Aldrete score and levels of vigilance, well-being, energy, nausea and agitation were recorded. Additionally, patients were contacted, when NFSC exceeded a predefined level. In cases of NRS>5, pain relief was achieved. Spearman-Rho correlation was calculated with SPSS.Results: 22 Patients underwent the study. Correlations were found between NFSC and Aldrete-Score, Vigilance, level of energy, as well as between SPI and NRS. Interestingly, NFSC and SPI did not present a correlation.Conclusions: SPI and NFSC failed to differentiate pain from other stressors. Since sympathetic activity is affected by various reasons, in sedated patients more success can be assumed. Further research is needed to develop more sophisticated compound parameters and algorithms. ^g>Acute pain therapy; post anaesthesia care unit; pain intensity measurement; skin conductance; surgical pleth index.
