電針療法對於體外授精的麻醉有效


Oct. 20, 2003--電針療法對於體外受精卵子蒐集的傳統麻醉顯然是有效的選擇!來自丹麥Skive Viborg 醫院的Peter S. Humaidan博士在美國德州聖安東尼奧舉行的美國生殖醫學協會的第59屆年會上口頭發表他們的研究發現。
  
  根據研究人員表示,早期電針療法的使用比傳統麻醉更費時,作者在研究摘要中提到,在現今的研究中,電針療法被應用於卵子收集前數分鐘,而使它在臨床使用上更具吸引力。
  
  在這項前瞻性隨機試驗中,Humaidan醫生和同事比較電針療法及傳統麻醉的期間的費用、病患的抱怨和麻醉或止痛的功效。
  
  共有200位進行體外授精和卵子收集的病患隨機分配到以電針療法和穿刺術組或是以麻醉前給藥、靜脈注射及子宮頸旁的傳統麻醉組。
  
  以目視疼痛評分表測量接受手續之前、期間和之後的焦慮與疼痛程度,在離開診所之後,病患持續在24小時內每六小時評估其疼痛狀況。
  
  以VAS測量的焦慮、預期的痛苦和手續前的疼痛程度在二組間是類似的,同樣地,手續後的痛苦程度,在診所和家中兩者皆類似。
  
  相較之下,在評估卵子收集期間的疼痛時,接受電針刺療法組比起傳統麻醉組有顯著較高的VAS疼痛評分,不過,有87%的病患對於卵子收集寧可再次選擇電針刺療法。
  
  一般而言,病患非常肯定電針刺療法,因為在卵子收集期間感覺較不困惑且更難忘,在當天休息時不會感到疲勞和昏昏欲睡。
  
  另外,使用止痛劑追加的準備及手續時間在二組間是類似,此外,在兩組中也發現每胚胎移入的高懷孕比例,然而,實行的費用和時間在電針刺療組較低。
  
  研究人員做出結論,由病患的高度評價,電針刺療法對於在卵子收集期間的傳統麻醉是一項很好的選擇。

Electro-Acupuncture Effective<

Oct. 20, 2003 — Electro-acupuncture appears to be an effective alternative to conventional anesthesia during egg collection (ovum pickup) for in vitro fertilization.

Peter S. Humaidan, MD, from the Viborg Hospital in Skive, Denmark, and colleagues presented their findings in an oral presentation at the 59th annual meeting of the American Society of Reproductive Medicine in San Antonio, Texas.

According to the researchers, previous use of electro-acupuncture suggests that it is more time-consuming than conventional anesthesia. In the current study, electro-acupuncture was applied a few minutes before ovum pickup, "making it more attractive for clinical use," the authors note in the study abstract.

In their prospective, randomized trial, Dr. Humaidan and colleagues compared duration, costs, patient compliance, and anesthetic/analgesic efficacy of electro-acupuncture to that of conventional anesthesia.

A total of 200 patients undergoing in vitro fertilization and ovum pick-up were randomized to receive electro-acupuncture and paracervical block or to conventional aesthesia with premedication, intravenous alfentanil, and paracervical block.

Anxiety before and pain level before, during, and after the procedure were measured using a visual analog scale (VAS). After leaving the clinic, patients continued to rate their pain every six hours for 24 hours.

Anxiety, expected pain, and pain levels before the procedure, as measured by VAS, were similar between the two groups. Likewise, pain levels after the procedure, both at the clinic and at home, were similar.

In contrast, when pain was assessed during the ovum pickup procedure, the group receiving electro-acupuncture had significantly higher VAS pain scores compared with the conventional anesthesia. "Nevertheless, 87% of patients would prefer electro-acupuncture again for ovum pickup," the researchers note.

"Generally patients were very positive to electro-acupuncture, feeling less confused and more present during the ovum pickup, and without tiredness and drowsiness for the rest of the day," they add.

The use of supplementary painkillers was similar between the two groups as was preparation and procedure time. In addition, high pregnancy rates per embryo transferred were seen in both groups.

However, costs and time to discharge were lower for the electro-acupuncture group.

"Electro-acupuncture is a good alternative to conventional anesthetics during ovum pickup, with a high patient compliance," the researchers conclude.
