Global Joint Entropy Algorithm-Based Evaluation of Dexmedetomidine Combined Local Anesthetics in Brachial Plexus Block from Ultrasound Images

This paper aimed to explore dexmedetomidine combined local anesthetics in brachial plexus block through ultrasound imaging (UI) under global joint entropy algorithm. Patients who underwent upper limb surgery and brachial plexus block were selected as research objects. Patients in group A were given...

Patients who underwent upper limb surgery and brachial plexus block were selected as research objects. Patients in group A were given 0.375% ropivacaine and normal saline, and patients in group B were given 0.375% ropivacaine and 1.0 μg/kg dexmedetomidine. The results of UI were analyzed by global joint entropy-based K-means clustering (GKC) algorithm, and the use effects of the two methods were compared in combination with other postanesthesia manifestations. The results were as follows. The segmentation accuracy (96.21% and 83.52%) of GKC was higher than 82.21% and 70.52% of the local joint entropy-based K-means clustering (LKC) (P<0.05). The duration of sensory and motor block (352.78 ± 45.89 min and 324.38 ± 41.29 min) in group B was significantly longer than 292.28 ± 35.69 min and 256.58 ± 42.76 min in group A (P<0.05). Compared with 84.91 ± 8.77 beats/min and 89.58 ± 7.62 beats/min in group A, mean arterial pressure (70.24 ± 9.77 beats/min and 69.89 ± 8.97 beats/min) in group B was lower at T1 and T2 (P<0.05). The duration of postoperative pain (582.70 ± 51.89 min) in group B was longer than 372.89 ± 49.89 min in group A (P<0.05). The postoperative pain score (2.98 ± 1.08) in group B was significantly lower than 4.48 ± 2.19 in group A (P<0.05). Therefore, dexmedetomidine combined local anesthetics could prolong the duration of sensory and motor nerve block. Besides, dexmedetomidine had sedative and analgesic effects, so as to prolong postoperative pain time and reduce pain degree of patients.Xiujuan GeXiaopeng SongLinyan LiHindawi LimitedarticleComputer softwareQA76.75-76.765ENScientific Programming, Vol 2021 (2021)
