过度换气治疗腰椎穿刺术后头痛的临床研究

Clinical Study on the Therapy of Hyperventilation in Patients with Puncture Headache

目的:探讨腰椎穿刺术后头痛的护理方法。方法:通过对56例腰穿剌后头痛患者经颅多普勒观察,发现腰穿后头痛与脑血管扩张有关。采用过度换气方法即让患者平卧位或侧卧位,过度换气3min,每分钟呼吸约40次,于3min后测定PaCO2。结果:有效42例,有效率75%。结论:腰穿后头痛患者采用过度换气方法,可造成轻度碱中毒,使脑血管收缩,纠正代偿性脑血管扩张,缓解头痛。该方法简便易行,见效快,护理中易实施。

abstract:To study the nursing methods to the patients with puncture headache after lumbar puncture. Methods:After recognizing the relationship between puncture headache and cerebrovascular dilation in 56 patients by Doppler's technique,hyperventilation was used to treat the headache patients with a respiratory rate of 40 times per minute for 3 minutes,and then CO pressure in blood was measured.Results:42 patients (75%) were recorded effective with the hyperventilation .Conclusions:Hyperventilation can induce a slight alkali poisoning and cerebrovascular contraction.This simple therapeutic method can effectively remedy the compensatory cerebrovascular dilation and to release headache symptom in lumbar puncturing patients.
