【摘要】:目的:本實(shí)驗(yàn)使用小劑量和大劑量右旋美托咪啶泵注用于婦科腹腔鏡手術(shù)術(shù)中維持,對(duì)比觀察其對(duì)術(shù)中七氟烷呼氣末濃度影響,同時(shí)觀察不同劑量右旋美托咪啶靜脈泵注復(fù)合七氟烷吸入麻醉用于婦科腹腔鏡手術(shù)的圍術(shù)期效果。 方法:選擇ASAⅠ~Ⅱ級(jí)擇期婦科腹腔鏡手術(shù)患者120例,年齡18~55歲,體重40-80kg,手術(shù)時(shí)間1-3h之內(nèi),手術(shù)類型為婦科良性疾病行腹腔鏡手術(shù),隨機(jī)雙盲分為S、D1、D2和D3組(n=30),所有患者不使用術(shù)前藥物。入室后監(jiān)測(cè)患者血壓、心率、心電圖、脈搏、SP02、BIS,建立靜脈通路,誘導(dǎo)前10分鐘D1、D2、D3組靜脈泵注1ug/kg右旋美托咪啶,S組輸注等容量生理鹽水,予以丙泊酚1.5mg/Kg、芬太尼5ug/Kg、維庫溴銨0.1mg/Kg全麻誘導(dǎo)插管。插管后D1、D2、D3組分別術(shù)中泵注0.2,0.4,1μg/kg/h右旋美托咪啶維持至手術(shù)結(jié)束,S組輸注等容量生理鹽水至手術(shù)結(jié)束。所有患者插管后機(jī)械通氣,氧流量1L/min,維持呼氣末二氧化碳(PetCO2)35~45mmHg。術(shù)中均復(fù)合七氟烷吸入麻醉至手術(shù)結(jié)束前五分鐘,維持BIS在40~45,術(shù)中間斷追加維庫溴銨,術(shù)畢給予托烷司瓊5mg后送返麻醉復(fù)蘇室。觀察并記錄麻醉前10分鐘(TQ)、氣管插管后即刻(T0)、插管后15分鐘(T1)、30分鐘(T2)、50分鐘(T3)、70分鐘(T4)、拔管即刻(T5)時(shí)間點(diǎn)的MAP、HR、SP02,以及T1、T2、T3、T4時(shí)間點(diǎn)的呼氣末七氟烷濃度,記錄拔管時(shí)間及圍術(shù)期患者不良反應(yīng)發(fā)生情況,并記錄處理措施。 結(jié)果: 1.一般資料比較:四組患者年齡、體重、手術(shù)時(shí)間差異無統(tǒng)計(jì)學(xué)意義(P0.05)。 2.四組患者平均動(dòng)脈壓(MAP)比較:4組患者麻醉前10分鐘比較MAP差異無統(tǒng)計(jì)學(xué)意義(P0.05);在氣管插管后即刻(T0)和拔管即刻(T5)兩時(shí)間點(diǎn)右旋美托咪啶組(D1、D2、D3組)與對(duì)照組(S組)比較,MAP均顯著降低,差異有顯著意義(P0.05),并且在T0、T5兩時(shí)間點(diǎn)S組與同組內(nèi)麻醉前TQ點(diǎn)比較MAP顯著增高,P 0.05;而在插管后15分鐘(T1)、30分鐘(T2)、50分鐘(T3)、70分鐘(T4)右旋美托咪啶組(D1、D2、D3組)與對(duì)照組(S組)比較MAP均顯著降低, P 0.05,并且在T1、T2、T3、T4時(shí)間點(diǎn)右旋美托咪啶組(D1、D2、D3組)與同組內(nèi)麻醉前TQ點(diǎn)比較MAP均顯著降低,差異有顯著意義,P 0.05;所有患者術(shù)中并未發(fā)生因?yàn)檠獕旱陀?0/60mmHg或者低于術(shù)前正常水平的30%而給予血管活性藥物改善的情況。 3.四組患者HR比較:4組患者麻醉前10分鐘比較HR差異無統(tǒng)計(jì)學(xué)意義(P0.05);在氣管插管后即刻(T0)和拔管即刻(T5)兩時(shí)間點(diǎn)右旋美托咪啶組(D1、D2、D3組)與對(duì)照組(S組)比較,HR均顯著降低,差異有顯著意義(P0.05),并且在T0、T5兩時(shí)間點(diǎn)S組與同組內(nèi)麻醉前TQ點(diǎn)比較HR顯著增高,P 0.05;而在插管后15分鐘(T1)、30分鐘(T2)、50分鐘(T3)、70分鐘(T4)右旋美托咪啶組(D1、D2、D3組)與對(duì)照組(S組)比較HR均顯著降低, P 0.05,并且在T1、T2、T3、T4時(shí)間點(diǎn)右旋美托咪啶組(D1、D2、D3組)與同組內(nèi)麻醉前TQ點(diǎn)比較HR均顯著降低,差異有顯著意義,P 0.05;D1和D2組分別有2例,D3組手術(shù)中出現(xiàn)3例,因?yàn)樾穆实陀?5次/分而需要使用阿托品處理。 4.呼氣末七氟烷濃度(ETSEVO):在手術(shù)中T1、T2、T3和T4四個(gè)時(shí)間點(diǎn),右旋美托咪啶組(D1、D2、D3組)與S組比較,呼氣末七氟烷濃度有明顯下降,差異有顯著意義,,P 0.05,其中3組數(shù)據(jù)中呼氣末七氟烷濃度最高下降60%,最低降低了41%(P 0.05);右旋美托咪啶組(D1、D2、D3組)3組組內(nèi)比較,D3組在T3和T4點(diǎn)相對(duì)偏低,但無統(tǒng)計(jì)學(xué)意義。 5.術(shù)后不良反應(yīng):所有患者均未出現(xiàn)呼吸抑制。S組有2例患者出現(xiàn)躁動(dòng)不安,原因?yàn)槟蚬懿贿m和輕度疼痛,右旋美托咪啶組(D1、D2、D3組)未出現(xiàn)躁動(dòng)患者;S組術(shù)后出現(xiàn)了7例寒顫反應(yīng),給予少量曲馬多后均緩解,D1、D2、D3組發(fā)生寒顫者分別為3例、2例和2例,(P 0.05);而D1和D3組均有4例患者術(shù)后口述口干,D2組則出現(xiàn)5例,我們采用蒸餾水濕潤(rùn)嘴唇來緩解癥狀。 結(jié)論: 1.右旋美托咪啶作為一種麻醉輔助用藥,能顯著減少術(shù)中呼氣末濃七氟烷濃度;并且右旋美托咪啶在小劑量0.2和0.4μg/kg/h泵注和大劑量1μg/kg/h泵注時(shí)減少呼氣末七氟烷濃度無明顯差異; 2.術(shù)中泵注右旋美托咪啶可以使圍術(shù)期血流動(dòng)力學(xué)平穩(wěn),降低寒顫發(fā)生率,減少躁動(dòng)發(fā)生,但口干發(fā)生率上升。
[Abstract]:Objective: the effect of small dose and large dose dexmedetomidine pump on the maintenance of gynecologic laparoscopic surgery was used to compare the effect of the seven fluorane end expiratory concentration in the operation, and the perioperative effect of different dosage of dexmedetomipridin combined with seven fluorothane inhalation anesthesia for gynecologic laparoscopic surgery was observed.
Methods: 120 patients with ASA I to second grade gynecologic laparoscopy were selected. The age 18~55 years old, the weight 40-80kg, the operation time within 1-3H, the operation type of gynecologic benign diseases underwent laparoscopic surgery. The patients were randomly divided into S, D1, D2 and D3 group (n=30). All patients were not treated with preoperative drugs. Blood pressure, heart rate, ECG, pulse were monitored after admission. Beat, SP02, BIS, establish venous access, induce D1, D2, D3 group intravenous infusion of dexmedetomidine, S group, S group, S group, S group, S, S group and other volume physiological saline, and give propofol 1.5mg/Kg, fentanyl 5ug/Kg, vecuronium 0.1mg/Kg general anesthesia induction intubation. Bundles, S group infusion of equal volume of normal saline to the end of operation. All patients after intubation mechanical ventilation, oxygen flow 1L/min, maintenance of end expiratory carbon dioxide (PetCO2) 35 ~ 45mmHg. combined with seven fluorothane inhalation anesthesia to five minutes before the end of the operation, maintaining BIS at 40~45, the operation in the middle of the addition of vecuronium, after the operation to the tsutecetron 5mg to return to return. The anesthesia resuscitation room was observed and recorded 10 minutes before anesthesia (TQ), immediately after endotracheal intubation (T0), 15 minutes after intubation (T1), 30 minutes (T2), 50 minutes (T3), 70 minutes (T4), MAP, HR, SP02, and T1, T2, and T1, T2, and 70 minutes (T4) at the time point of T5, recording the time of extubation and the occurrence of adverse reactions in the perioperative patients, and Record treatment measures.
