摘要:

目的 探究一种新型智能型可穿戴式经皮胫神经刺激器在不同刺激参数下对猫生理性膀胱反射的抑制作用。

方法 18只猫分为强度组、频率组和波形组,将胫神经刺激器穿戴在猫的内踝处,分别采用不同阈值(T)强度(1/2 T、1 T、3/2 T、2 T)、刺激频率(5 Hz、10 Hz、15 Hz、30 Hz)和波形(波形A、波形B)行胫神经刺激(TNS)。麻醉后,向猫的膀胱缓慢灌注生理盐水,诱发膀胱反射,同时进行膀胱压力容积测定。比较各组膀胱测压图。

结果 不同强度刺激后,膀胱容量无显著性差异(F = 1.997, P = 0.126),其中3/2 T和2 T刺激时,膀胱容量高于基础膀胱容量(P < 0.05)。不同频率刺激后,膀胱容量有显著性差异(F = 3.894, P = 0.014),5 Hz、10 Hz和15 Hz刺激后,膀胱容量高于基础膀胱容量(P < 0.05)。不同波形刺激后,膀胱容量有显著性差异(F = 5.184, P = 0.019),波形A刺激后,膀胱容量高于基础膀胱容量(P < 0.05)。

结论 新型智能型可穿戴式经皮胫神经刺激器能有效抑制猫生理膀胱反射,抑制效果与刺激强度、频率和波形有关。

Abstract:

Objective To observe the inhibitory effects of a novel wearable transcutaneous tibial nerve stimulator on bladder reflex in cats under different stimulation parameters.

Methods A total of 18 cats were divided into intensities, frequencies and waveforms groups, which wore the stimulator on the ankles and stimulated in different threshold (T) intensities (1/2 T, 1 T, 3/2 T and 2 T), frequencies (5 Hz, 10 Hz, 15 Hz and 30 Hz) and waveforms (A and B). The cats were anesthetized and infused normal saline to induce bladder reflex, while the bladder capacity was measured. Cystometrograms were compared among stimulation parameters.

Results The bladder capacity was not significantly different among the intensities (F = 1.997, P = 0.126), while the bladder capacity was more after TNS of 3/2 T and 2 T than baseline (P < 0.05). The bladder capacity was significantly different among the frequencies (F = 3.894, P = 0.014), while the bladder capacity was more after 5 Hz, 10 Hz and 15 Hz of TNS (P < 0.05). The bladder capacity was significantly different between the waveforms (F = 5.184, P = 0.019), while the bladder capacity was more after waveform A of TNS than baseline (P < 0.05).

Conclusion The novel wearable transcutaneous tibial nerve stimulator can effectively inhibit the physiological bladder reflex in cats, which associates to the intensity, frequency and waveform of stimulation.
