異丙酚 吸脂 甘油三酯 游離脂肪酸
異丙酚是由2,6二異丙基溶解于10%的大豆油、1.2%的軟磷脂及2.25%的甘油組成的水溶性乳劑[1]。異丙酚主要是通過(guò)阻止脂質(zhì)進(jìn)行beta氧化對(duì)脂代謝產(chǎn)生影響[2]。吸脂手術(shù)由于手術(shù)直接吸取脂肪組織,將脂質(zhì)物質(zhì)帶入血循環(huán)而引起血脂變化,在吸脂手術(shù)中靜脈輸注異丙酚是否會(huì)協(xié)同影響脂質(zhì)代謝尚不清楚,本文探討術(shù)中靜脈輸注異丙酚40~60μg/(kg·min)對(duì)吸脂患者的脂質(zhì)代謝的影響。
1.1 一般資料 2015年7 月至2016年10月本院行雙大腿吸脂術(shù)的女性患者60例,年齡18~60歲,體重40~80kg,ASAⅠ~Ⅱ級(jí),無(wú)高血壓和高脂血癥,凝血功能正常。隨機(jī)分為2組,每組各30例。兩組患者均在非插管全身麻醉下行雙大腿吸脂術(shù),患者入手術(shù)室后常規(guī)生命體征監(jiān)測(cè),面罩吸氧,給予咪唑安定2mg,地佐辛5mg,手術(shù)時(shí)間1.5h左右,術(shù)中維持Ⅰ組微泵給予異丙酚40~60μg/(kg·min)和瑞芬太尼0.05~0.10μg/(kg·min);Ⅱ組給予瑞芬太尼0.10~0.16 μg/(kg·min)。手術(shù)部位采取局部腫脹麻醉,配方:利多卡因600mg,腎上腺素1mg,生理鹽水1000ml。術(shù)中保持自主呼吸,手術(shù)結(jié)束停藥。
1.2 方法 記錄手術(shù)時(shí)間,麻醉時(shí)間。分別在術(shù)前(T1),手術(shù)結(jié)束后(T2),術(shù)后2h(T3)取靜脈血2ml,檢測(cè)甘油三酯(TG)和游離脂肪酸(FFA)的濃度。1.3 統(tǒng)計(jì)學(xué)方法 采用SPSS11.5統(tǒng)計(jì)軟件。計(jì)量資料以(x±s)表示,組內(nèi)比較采用重復(fù)測(cè)量設(shè)計(jì)的方差分析,計(jì)數(shù)資料比較采用卡方檢驗(yàn),P<0.05為差異有統(tǒng)計(jì)學(xué)意義。
2.1 兩組患者一般情況比較 見(jiàn)表1。
表1 兩組患者一般情況比較[n=30,(x±s)]
2.2 兩組各時(shí)點(diǎn)血清TG和FFA的濃度比較 見(jiàn)表2。
表2 兩組各時(shí)點(diǎn)血清TG和FFA的濃度比較[n=30,(x±s)]
高脂血癥是指當(dāng)血漿或血清脂質(zhì)高于正常值的上限,血脂包括甘油三酯、膽固醇、膽固醇酯、各種磷脂及游離脂肪酸等。靜脈血液檢查符合以下一項(xiàng)即可診斷為高脂血癥:TG>1.88mmol/dl,F(xiàn)FA>900μmol/dl。
以往研究表明,異丙酚對(duì)術(shù)后脂質(zhì)代謝具有影響[3],主要由于異丙酚是脂溶性溶劑,長(zhǎng)時(shí)間大劑量的應(yīng)用可能會(huì)導(dǎo)致高脂血癥。相關(guān)研究表明,異丙酚能夠阻止脂質(zhì)氧化,對(duì)脂肪代謝產(chǎn)生影響[4]。異丙酚能夠促使氧化呼吸鏈傳導(dǎo)障礙使細(xì)胞紋理喪失,形成空泡,使轉(zhuǎn)運(yùn)脂質(zhì)的過(guò)程受阻,從而形成高脂血癥。本資料顯示,靜脈注射小劑量異丙酚40~60μg/(kg·min)與未使用異丙酚靜脈麻醉對(duì)TG、FFA的代謝無(wú)明顯差異,提示異丙酚靜脈注射在吸脂手術(shù)結(jié)束至術(shù)后2h對(duì)脂質(zhì)代謝無(wú)影響。
吸脂手術(shù)時(shí),吸脂棒打碎的部分脂肪,通過(guò)破裂的血管進(jìn)入全身循環(huán)系統(tǒng),如用超聲乳化技術(shù),將有更多的脂肪被吸收[5]。吸脂術(shù)本身會(huì)導(dǎo)致血脂水平的增高。Vandeweyer[6]對(duì)10例平均吸脂量為1470ml(500~2800ml)的受術(shù)者,分別在術(shù)前,手術(shù)進(jìn)行20min,術(shù)后的1h和4h監(jiān)測(cè)TC、HDL-C、LDL-C、TG、LPa等,發(fā)現(xiàn)在手術(shù)進(jìn)行20min和術(shù)后1h時(shí)各值均有所增高,而在術(shù)后4h恢復(fù)至原值。本資料顯示,吸脂手術(shù)結(jié)束時(shí)患者血中的FFA明顯增高,2h后回落,但也明顯高于正常。TG在手術(shù)結(jié)束時(shí),上升不明顯,2h后逐漸回落至正常水平以下。
綜上所述,小劑量異丙酚靜脈輸注術(shù)后2h對(duì)吸脂患者TG、FFA代謝無(wú)顯著影響。而吸脂術(shù)會(huì)導(dǎo)致患者手術(shù)結(jié)束時(shí)至術(shù)后2h TG先升高再下降,幅度較小,F(xiàn)FA先明顯增高再緩慢下降,兩者在術(shù)后多長(zhǎng)時(shí)間恢復(fù)至正常有待進(jìn)一步研究。

Objective To investigate the effects of less doses infusion of propofol during liposuction on the blood lipidogram. Methods Sixty female patients selected for bilateral thighs liposuction were randomly divided into two groups(n=30),maintenance of anesthesia during the operation,group Ⅰ was
infusion of propofol and remifentani while group Ⅱ with infusion of remifentani.2cc blood samples were taken from vein immediately for determination of triglyeride(TG),free fatty acid(FFA)were recorded before anesthesia induction(T1),at 1,2h after the end of operation(T2),(T3). Results Compared with those at T1,the triglyeride(TG)were increased unconspicuous at T2,and decreased at T3. All the parameters in the 2 groups were in the normal ranges. There was no significant difference between group 1and group Ⅱ. Compared with those at T1,free fatty acid(FFA),concentrations were significantly increased at(T2),and lower at(T3). There was no significant difference between group Ⅰ and group Ⅱ. Conclusion After 2h infused with less doses of propofol to liposuction patient during operation,There is no significant influence with triglyeride(TG)and free fatty acid(FFA).But only liposuction can made the triglyeride(TG) increased unconspicuous after operation.And free fatty acid(FFA),concentrations are significantly increased at 1h after operation,and lower at 2h after operation. Both of them are significant difference.
