To study the ultrasound guiding by methylenum coeruleum thoracic paravertebral block analgesia effect and promote healing of herpes zoster.
A total of 87 patients with herpes zoster were randomly divided into an observation group and a control group, and the two groups received the same treatment including antiviral drug, nerve nutrition, in order to increase the body's resistance. The observation group were given thoracic paravertebral block with methylenum coeruleum guided by ultrasound, recorded visual analogue scale (VAS) of the two groups of patients for their hypersensitivity to pain 1d, 3d, 1 week, 2 weeks, 1 month after treatment, skin lesion healing time, incidence of postherpetic neuralgia (PHN), patients’ satisfaction, etc.
After administration of thoracic paravertebral block with methylenum coeruleum, VAS of the observation group expectedly decreased. At the same time, the VAS in the observation group was significantly lower than that in the control group, the skin healing time in the observation group was obviously shorter, and the incidence of PHN was lower than that in the control group. The satisfaction of observation group patients was higher than that in the control group (P<0.05).
To implement thoracic paravertebral block with methylenum coeruleum guided by ultrasound can help reduce the degree of hypersensitivity to pain, promoting the healing of herpes zoster could reduce the incidence of PHN, greatly improving patients’ satisfaction.Le texte complet de cet article est disponible en PDF.
