[Abstract] Objective To evaluate the effect of Magnesium Sulfate to prevent shivering during cesarean section. Methods Databases including PubMed， The Cochrane Library （Issue 8， 2019）， EMbase， Wanfang Data Knowledge Service Platform （WanFang Data）， China National Knowledge Infrastructure （CNKI）， China Biology Medicine disc （CBM） were searched for computer to collect the randomized controlled trails （RCT） about the effect of Magnesium Sulfate on shivering for cesarean section. The retrieval time limit from repository to August 2019. The literature was tracked based on the references included in the RCT. Meta-analysis was conducted using RevMan 5.3 software， GRADE of evidence quality was used to evaluate the evidence level of meta-analysis results. Results Finally， 15 references were included， including 1043 patients and 532 patients with Magnesium Sulfate. The results of meta-analysis showed that： the incidence of shivering in experimental group was lower than that in control group （RR = 0.48， 95%CI：0.37-0.63， P < 0.000 01）. The incidence of shivering in intravenous subgroup was lower than that in control group （RR = 0.46， 95%CI：0.33-0.66， P < 0.0001）; the incidence of shivering in subarachnoid injection subgroup had no statistically significant difference compared with control group （P = 0.12）; the incidence of shivering in epidural injection subgroup was lower than that in control group （RR = 0.38， 95%CI：0.21-0.67， P = 0.0009）. The incidence of shivering in subarachnoid anesthesia subgroup was lower than that in control group （RR = 0.53， 95%CI： 0.36-0.78， P = 0.001）; the incidence of shivering in combined lumbar and epidural anesthesia subgroup was lower than that in control group （RR = 0.45， 95%CI： 0.29-0.68， P = 0.0002）. Meta-analysis results for different administration subgroups were all evaluated as “Moderate”. Conclusion Intravenous injection and epidural injection of Magnesium Sulfate can prevent shivering in cesarean section， but the effect of subarachnoid injection of Magnesium Sulfate to prevent the occurrence of shivering in cesarean section remains to be evaluated.

蛛網(wǎng)膜下腔麻醉是剖宮產(chǎn)術(shù)常用的麻醉方式，具有起效快、麻醉效果確切等諸多優(yōu)點(diǎn)。硫酸鎂具有抑制子宮收縮、治療胎兒宮內(nèi)窘迫的作用。本研究中有6篇[9，11，13，15-17]經(jīng)蛛網(wǎng)膜下腔注射硫酸鎂，但亞組分析結(jié)果卻顯示，硫酸鎂蛛網(wǎng)膜下腔注射亞組產(chǎn)婦寒戰(zhàn)發(fā)生率與對(duì)照組比較，差異無統(tǒng)計(jì)學(xué)意義（P = 0.12），在預(yù)防剖宮產(chǎn)術(shù)寒戰(zhàn)方面并未體現(xiàn)出明顯優(yōu)勢(shì)。在3種給藥方式中，靜脈注射硫酸鎂能夠使藥物快速發(fā)揮其藥理作用。研究顯示[8，17]，蛛網(wǎng)膜下腔注射、硬膜外注射硫酸鎂具有較高安全性。與蛛網(wǎng)膜下腔注射比較，硬膜外注射后，藥物沿硬膜外間隙上下擴(kuò)散，在此過程中部分藥物經(jīng)毛細(xì)血管吸收入血而發(fā)揮作用，但蛛網(wǎng)膜下腔注射給藥并無上述過程[24]。因此，蛛網(wǎng)膜下腔注射與硬膜外注射的上述區(qū)別可能是導(dǎo)致蛛網(wǎng)膜下腔注射硫酸鎂在預(yù)防寒戰(zhàn)方面效果不佳的原因。

本研究共納入15篇[7-21]RCT，其中7篇[8，11-12，14-15，17-18]采用分配隱藏，納入研究整體質(zhì)量尚可但仍存在局限性。首先，所納入部分研究未報(bào)告研究對(duì)象年齡、各研究間硫酸鎂用藥劑量不同，可能影響本研究結(jié)果的可靠性;其次，15篇[7-21]RCT均為小樣本量，所得結(jié)論仍需進(jìn)一步加以明確;最后，硫酸鎂不同給藥方式的亞組meta分析結(jié)果質(zhì)量等級(jí)均為“Moderate（中）”，故所得結(jié)論仍需更多高質(zhì)量RCT加以驗(yàn)證。

綜上所述，靜脈注射、硬膜外注射硫酸鎂能夠預(yù)防行剖宮產(chǎn)術(shù)產(chǎn)婦寒戰(zhàn)的發(fā)生，但蛛網(wǎng)膜下腔注射硫酸鎂預(yù)防行剖宮產(chǎn)術(shù)產(chǎn)婦寒戰(zhàn)的效果尚待評(píng)估。
