[摘要] 目的 探討剖宮產(chǎn)術(shù)中應(yīng)用右美托咪定對(duì)椎管內(nèi)麻醉期間寒顫、牽拉反應(yīng)的預(yù)防效果。 方法 入選2018年1～10月的剖宮產(chǎn)患者80例，隨機(jī)分成對(duì)照組與觀(guān)察組，各40例，兩組患者在分娩中以剖宮產(chǎn)的方式分娩，并在胎兒剖出之后，對(duì)照組給予生理鹽水進(jìn)行靜脈滴注，觀(guān)察組應(yīng)用右美托咪定靜脈滴注，經(jīng)過(guò)不同的干預(yù)治療后比較兩組對(duì)椎管內(nèi)麻醉期間寒顫、牽拉反應(yīng)的預(yù)防效果。 結(jié)果 觀(guān)察組的寒顫發(fā)生率為12.50%，明顯低于對(duì)照組的25.00%，差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。在牽拉反應(yīng)的預(yù)防中，觀(guān)察組的預(yù)防優(yōu)良率為90.00%，明顯高于對(duì)照組的77.50%，差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。觀(guān)察組與對(duì)照組的不良反應(yīng)發(fā)生率分別為7.50%與10.00%，差異無(wú)統(tǒng)計(jì)學(xué)意義（P>0.05）。 結(jié)論 剖宮產(chǎn)術(shù)中應(yīng)用右美托咪定可以對(duì)椎管內(nèi)麻醉期間寒顫、牽拉反應(yīng)起到良好的預(yù)防效果，值得在臨床中廣泛應(yīng)用。

[Abstract] Objective To investigate the preventive effect of dexmedetomidine on chills and traction response during spinal anesthesia in cesarean section. Methods Eighty patients who received cesarean section from January to October 2018 were enrolled and randomLy divided into the control group and the observation group， each had 40 cases. Cesarean section was selected as the delivery method in both groups. After the fetuses were born， the control group was given intravenous infusion of saline and the observation group was given intravenous infusion of dexmedetomidine. After different intervention treatment， the preventive effects on chills and traction response during spinal anesthesia were compared between the two groups. Results The incidence of chills in the observation group was 12.50%， which was significantly lower than the 25.00% in the control group， with statistically significant difference（P<0.05）. In the prevention of traction response， the excellent and good rate of prevention in the observation group was 90.00%， which was significantly higher than the 77.50% of the control group， with statistically significant difference（P<0.05）. The incidences of adverse reactions in the observation group and the control group were 7.50% and 10.00%， respectively， with no statistically significant difference（P>0.05）. Conclusion The use of dexmedetomidine in cesarean section shows a good preventive effect on chills and traction response during spinal anesthesia， which is worthy of wide clinical application.

分娩是胎兒自母體離開(kāi)而獨(dú)立的過(guò)程，是終止妊娠的生理過(guò)程，分娩時(shí)產(chǎn)婦可以通過(guò)產(chǎn)道自然分娩出胎兒，也可經(jīng)腹部切開(kāi)子宮將胎兒分娩出，即在臨床中分娩方式包括自然分娩和剖宮產(chǎn)分娩，雖然自然分娩為有利于胎兒和母體的分娩方式，但是在臨床中剖宮產(chǎn)同時(shí)占有較高的比例[1]。特別是隨著營(yíng)養(yǎng)水平的提高，胎兒過(guò)大的比例在不斷增加，進(jìn)而剖宮產(chǎn)在臨床中的應(yīng)用率不斷增加，剖宮產(chǎn)手術(shù)前麻醉一般采取腰椎管內(nèi)的麻醉，麻醉后患者出現(xiàn)寒顫;牽拉反應(yīng)等并發(fā)癥的情況較多，患者會(huì)出現(xiàn)寒顫，肌肉緊張，牽拉疼痛等，容易增加機(jī)體的耗氧量，影響自身的代謝反應(yīng)，在手術(shù)中出現(xiàn)寒顫直接影響產(chǎn)婦和胎兒的健康，同時(shí)寒顫和牽拉反應(yīng)的發(fā)生對(duì)術(shù)后的身體恢復(fù)造成一定的不良影響，給患者的心理帶來(lái)負(fù)面的影響，容易增加產(chǎn)后抑郁的發(fā)生比例[2-3]。因此，有效的預(yù)防剖宮產(chǎn)患者椎管內(nèi)麻醉期間寒顫、牽拉反應(yīng)很有必要。本研究在剖宮產(chǎn)術(shù)中應(yīng)用右美托咪定對(duì)椎管內(nèi)麻醉期間寒顫、牽拉反應(yīng)進(jìn)行預(yù)防的效果比較突出，現(xiàn)報(bào)道如下。
