“…The areas of cold hypoesthesia were tested using ice, which relies mainly on the patient's own judgment of cold rather than an objective judgment criterion. Indeed, changes in skin blood flow can be monitored by photoplethysmography or laser Doppler during a nerve block, which is a more reliable and sensitive technique than a subjective assessment of skin temperature changes (27). Second, the areas of cold hypoesthesia were tested at different time points after ESPB, but the area of sensory loss was not tested, and the recovery of postoperative sensation was not recorded.…”

BACKGROUND: The erector spinae plane block (ESPB) is gaining popularity in lumbar fusion for postoperative pain management. OBJECTIVES: The aim of this study was to investigate the changes of opioid consumption after surgery, the range of cold temperature sensory blockade, pain, and safety. STUDY DESIGN: Randomized controlled study. SETTING: Single center. METHODS: Patients who were randomized to ESPB with 0.375% ropivacaine (ropivacaine group) and mock ESPB with saline (saline group) and underwent posterior lumbar fusion surgery. The primary endpoint was the total dosage of oxycodone. Secondary endpoints included remifentanil consumption, postoperative pain scores, postoperative adverse events, safety, and range of cold hypoesthesia. RESULTS: Oxycodone consumption in the first 48 hours after surgery was significantly lower in the ropivacaine group than in the saline group (P < 0.05). Remifentanil consumption was significantly lower in the ropivacaine group compared with the saline group during the surgery (0.69 ± 0.03 mg vs. 0.85 ± 0.04 mg, P < 0.05). The areas of cold hypoesthesia were identified in the ropivacaine group after the block, but not in the saline group. Rest and exercise pain scores after surgery were significantly lower in the ropivacaine group than in the saline group (P < 0.05). The overall safety of the ropivacaine group were generally comparable to that of the saline group. LIMITATIONS: The areas of cold hypoesthesia were tested at different time points after ESPB, but the area of sensory loss was not tested, and the recovery of postoperative sensation was not recorded. In addition, we tested only temperature sensation, but not acupuncture pain. CONCLUSIONS: Ultrasound-guided lumbar ESPB reduces the amount of analgesics required during and after lumbar fusion and reduces the postoperative Visual Analog Scale pain score.

“…Firstly, we only observed temperature fluctuations at the waist after taping. As a core region of the human body, the temperature of the waist is relatively high with little fluctuation, while the temperature of the distal extremities may be more susceptible to external intervention (Hermanns et al, 2018). Secondly, it has been reported that skin temperature distribution is influenced by the subcutaneous fat of each body segment.…”

Background: There were limited studies on the effect of skin temperature and local blood flow using kinesio tape (KT) adhered to the skin in different taping methods. This study aimed to determine the short-term effect of KT and athletic tape (AT) on skin temperature in the lower back and explore the possible effect of different taping methods (Y-strip and fan-strip taping) on local microcirculation. Materials and Methods: Twenty-six healthy participants completed the test-retest reliability measurement of the infrared thermography (IRT), intraclass correlation coefficient (ICC), and standard error of measurement (SEM) were calculated to evaluate the reliability. Then, 21 healthy participants received different taping condition randomly for 5 times, including Y-strip of kinesio taping (KY), fan-strip of kinesio taping (Kfan), Y-strip of athletic taping (AY), fan-strip of athletic taping (Afan), and no taping (NT). Above taping methods were applied to the participants' erector spinae muscles on the same side. Skin temperature of range of interest (ROI) was measured in the taping area through IRT at pre taping and 10 min after taping. Additionally, participants completed self-perceived temperature evaluation for different taping methods through visual analog scaling. One-way repeated-measured analysis of variance was used to compare the temperature difference among different taping methods. Bonferroni test was used for post hoc analysis. Results: There was a good test-retest reliability (ICC = 0.82, 95% CI = 0.60-0.92; SEM = 0.33; and MD = 0.91) of the IRT. Significant differences were observed in the short-term effect on skin temperature among all different taping methods (p = 0.012, F = 3.435, and η p 2 = 0.147), post hoc test showed a higher significantly skin temperature difference in Kfan taping compared to no taping (p = 0.026, 95% CI = 0.051-1.206); However, no significant differences were observed among self-perceived temperature (p = 0.055, F = 2.428, and η p 2 = 0.108).

“…This type of temperature change can be detected by infrared thermography. Infrared thermography has been successfully applied in predicting the effectiveness of various regional blocks including upper and lower extremity block, epidural and spinal anesthesia [12]. However, its usefulness in TPVB has not been determined.…”

Background: There was no “gold standard” to assess the success or failure of thoracic paravertebral block (TPVB). Measurement of skin temperature with infrared thermography (IT) would be a reliable method to evaluate the effectiveness of regional blocks. This study aimed to explore the feasibility of using skin temperature difference (Td) determined by IT between the blocked and unblocked side to predict the outcome of TPVB. Methods: Sixty-one patients undergoing elective unilateral breast or thoracoscopic surgery were enrolled in this prospective observational study. TPVB was performed at T4 and T5 under real-time ultrasound guidance with 10 mL of 0.4% ropivacaine for each patient, respectively. Td between the blocked and unblocked side were measured with IT from T2 to T10 at the anterior chest wall before TPVB and 5 min, 10 min, 15 min and 20 min after TPVB. Pinprick test was performed at 20 min after TPVB. Successful TPVB was defined as no sensation to pinprick in 3 or more adjacent dermatomes corresponding to the site of injection at 20 min after TPVB. Td was compared to pinprick test for evaluating its effectiveness in predicting the success of TPVB. The sensitivity, specificity, and cut-off value of Td for predicting successful TPVB were determined by receiver operator characteristic (ROC) curve analysis.Results: Compared with the baseline value before block, Td from T2 to T10 were significantly increased at each time point in successful blocks. In failed blocks, Td was not increased in any dermatome. The increase of Td at T4-T7 was more than 1℃ 20 min after successful TPVB. Fifteen minutes after block, Td increase at T4 had the greatest potential to predict block success. The area under the ROC curve was 0.960 at a cut-off value of 0.63℃ with a sensitivity of 83.3% and a specificity of 100.0%.Conclusions: This study suggested that the increase of Td at T4 dermatome determined by IT between the blocked and unblocked side is an early, quantitative, and reliable predictor of successful TPVB.
