摘　　要：目的:观察低频脉冲治疗防治胸腔镜术后患者不良反应的效果。方法:采用工作频率为15 Hz,最大输出电流在500Ω负载电阻下≤50 mA,输出电流稳定度在500Ω负载电阻上下波动±10%时变化率≤10%,脉冲宽度为25~30μs(半高宽)的低频脉冲治仪对胸腔镜术后患者进行术后恶心呕吐(PONV)不良反应防治干预。选取在医院行胸腔镜肺叶切除术的400例患者,采用随机数表法将其分为对照组和观察组,每组200例,对照组采用常规护理,观察组在常规护理基础上采用低频脉冲治疗,比较两组患者术后呕吐发生率和恶心呕吐干呕指数(INVR)评分。结果:观察组患者恶心、呕吐和干呕的INVR评分分别为(8.25±3.58)分、(6.365±1.96)分和(10.52±1.33)分,均低于对照组,两组比较差异有统计学意义(t=8.25,t=20.61,t=17.51;P<0.05);观察组呕吐发生率为8.5%,低于对照组,两组比较差异有统计学意义(χ^(2)=4.251,P<0.05)。结论:低频脉冲治疗防治胸腔镜术后患者不良反应中的恶心呕吐效果明显,利于胃肠功能恢复,具有较高的临床应用价值。Objective:To observe the effect of low-frequency pulse therapy on the prevention and treatment of postoperative adverse reactions in patients after thoracoscopic surgery.Methods:A low-frequency pulse therapy instrument with working frequency of 15 Hz,maximum output current of≤50 mA under load resistance of 500Ω,change rate of≤10%when the output current stability fluctuates±10%under a 500Ωload resistance,and pulse width of 25 to 30 us(half height width)was used for prevention and treatment of postoperative nausea and vomiting(PONV)adverse reactions in patients after thoracoscopic surgery.A total of 400 patients undergoing thoracoscopic lobectomy in the hospital were selected and divided into control group and observation group by random number table method,with 200 patients in each group.The control group adopted conventional nursing,the observation group adopted low-frequency pulse therapy on the basis of conventional nursing.The incidence of postoperative vomiting and the score of Index of Nausea and Vomiting and Retching(INVR)were compared between the two groups.Results:The INVR scores of nausea,vomiting,and retching in the observation group were(8.25±3.58),(6.365±1.96),and(10.52±1.33),respectively,all of which were lower than those in the control group,and the differences between the groups were statistically significant(t=8.25,t=20.61,t=17.51,P<0.05).The incidence of vomiting in the observation group was 8.5%,which was lower than that in the control group,and the difference between the groups was statistically significant(χ^(2)=4.251,P<0.05).Conclusion:Low frequency pulse therapy is effective in the prevention and treatment of nausea and vomiting in patients with adverse reactions after thoracoscopic surgery,which is beneficial to the recovery of gastrointestinal function and has high clinical application value.
