Methods A total of 60 patients aged from 18 to 65 years, admitted from January to March 2009 and scheduled to undergo elective CO2-LELM under general anesthesia for treatment of vocal cord polyp were randomly assigned to a propofol group, an esmolol group, and a remifentanil group. Anesthesia was induced with midazolam (0.015-0.02 mg/kg), fentanyl (1 μg/kg), and propofol (1 mg/kg). After the patients became unconscious, succinylcholine (1 mg/kg) was given one minute later. Then the patients in the three groups received propofol (2 mg/kg), esmolol (1 mg/kg), and remifentanil (1 μg/kg), respectively. Intubation was performed 30 secconds later. Heart rate (HR) and systolic blood pressure (SBP) were measured noninvasively before general anesthesia induction (baseline, Tb), just before intubation(Ti), and one, three, and five minutes after intubation (T1, T3, T5). Results The demographic data including age, sex and body weight were comparable in the three groups. Tracheal intubation caused significant increases in SBP and HR in all groups compared with Ti (Plt;0.05). After intubation, SBP in the propofol group and the esmolol group were significantly higher than that in remifentanil group (Plt;0.05), and HR in the propofol group was significantly higher than that in the remifentanil group (Plt;0.05). Conclusion In patients with CO2-LELM, remifentanil (1 μg/kg) administrated 30 seconds before intubation is maximal effective compared with propofol (2 mg/kg) or esmolol (1 mg/kg) in attenuating the hemodynamic responses to oraltracheal intubation.
目的 系統評價瑞芬太尼用于全身麻醉下剖宮產時對新生兒的影響。 方法 檢索Cochrane Library、PubMed、OVID、EMbase、CNKI、萬方等中外數據庫，收集1990年－2012年關于瑞芬太尼用于全身麻醉下剖宮產的臨床隨機對照研究。按Cochrane系統評價方法評估文獻質量，用Revman 5.1軟件對提取的數據進行Meta分析。 結果 共納入10項研究，包括342例產婦。與空白對照組相比，瑞芬太尼降低新生兒1 min Apgar評分[WMD=?0.46，95%CI（?0.65，?0.27），P＜0.000 01]，提高出生時臍動脈pH值[WMD=0.01，95%CI（0.00，0.02），P=0.004]，增加出生時窒息發生率[RR=1.76，95%CI（1.06，2.95），P=0.03]；當誘導劑量為1.0～1.5 μg/kg時，對5 min Apgar評分無影響[WMD=?0.14，95%CI（?0.32，0.04），P=0.13]。 結論 瑞芬太尼用于全身麻醉剖宮產可減輕新生兒酸中毒，但是會對新生兒產生一過性的呼吸抑制。
ObjectiveTo evaluate the feasibility and efficiency of patient-controlled analgesia and sedation (PCAS) with propofol and remifentanil for colonoscopy in elderly patients. MethodsSixty elderly patients preparing for painless colonoscopy between May and September 2015 were randomly allocated into PCAS group and total intravenous anesthesia (TIVA) group with 30 patients in each. In the PCAS group, the mixture of remifentanil and propofol at 0.6 mL/(kg·h) was pumped continuously after an initial bolus of 0.05 mL/kg mixture. The examination began three minutes after the infusion was finished. Patients could press the self-control button. Each bolus delivered 1 mL and the lockout time was 1 minute. In the TIVA group, patients received fentanyl at 1 μg/kg and midazolam at 0.02 mg/kg intravenously, and accepted intravenous propofol at 0.8-1.0 mg/kg two minutes later. The examination began when the patients lost consciousness. ResultsA significant decline of mean arterial blood pressure was detected within each group after anesthesia (P < 0.05). The decrease of mean blood pressure in the TIVA group was more significant than that in the PCAS group (P < 0.05). The heart rate, pulse oxygen saturation and respiratory rate decreased significantly after anesthesia in both the two groups (P < 0.05), while end-tidal CO2 increased after anesthesia without any significant difference between the two groups (P > 0.05). The induction time, time to insert the colonoscope to ileocecus, and total examination time were not significantly different between the two groups (P > 0.05). As for the time from the end of examination to OAA/S score of 5 and to Aldrete score of 9, the PCAS group was significantly shorter than the TIVA group (P < 0.05). ConclusionPCAS with remifentanil and propofol can provide sufficient analgesia, better hemodynamic stability, lighter sedation, and faster recovery compared with TIVA.
The present study was to investigate the effects of infusing remifentanil-poly-caprolactone (REM-PCL) through the abdominal aorta on spinal cord ischemia reperfusion injury (SCIRI). The model of SCIRI was created by clamping the infrarenal aortic in thirty-six New Zealand white rabbits, which were randomly divided into sham group (group S), control group (group C), and REM-PCL group (group R) with 12 rabbits in each one. The spinal cord microcirculatory blood flow (SCMBF) and blood flow rate (BFR) were monitored before ischemia, 15 min, 30 min, 60 min and 120 min after reperfusion, respectively. Neurologic Function was evaluated before ischemia, 6h, 12h and 24h after reperfusion. The concentration of serum neuron-specific enolase (NSE), interleukin-lβ (IL-lβ) and interleukin-8 (IL-8) were monitored before ischemia, 45 min after ischemia, 30 min, 60 min, 6 h, 12 h and 24 h after reperfusion. The abnormal rate of motor neuron of spinal cord tissues and the level of superoxide dismutase (SOD), reactive oxygen species (ROS), glutathione peroxidase (GSH-PX), malondialdehyde (MDA), total anti-oxidation capacity (T-AOC) and mitochondrial swelling degree (MSD) in neural mitochondria were determined before ischemia, 45 min after clamping, 60 min and 120 min after reperfusion. As a result, the neural mitochondrial SOD, GSH-PX and T-AOC decreased while ROS, MDA, MSD, IL-lβ, IL-8 and NSE distinctly increased after clamping of the abdominal aorta as compared to the value before ischemia in group C (P < 0.01). Neurologic function scores recovered more rapidly in group R than those in group C during reperfusion (P < 0.01). The neural mitochondrial SOD, GSH-PX and T-AOC were distinctly higher while ROS, MDA, MSD, IL-lβ, IL-8 and NSE were distinctly lower in group R than those in group C (P < 0.01). The abnormal rate of motor neuron was significantly higher in group C during reperfusion than that in group R (P < 0.01). It has been shown that the intra-aortic REM-PCL infusion can alleviate SCIRI by inhibiting inflammatory response and improving mitochondrial anti-oxidation capacity.
目的:比較瑞芬太尼聯合異丙酚或依托咪酯全麻在腹腔鏡婦科手術中的臨床效果。方法:擇期腹腔鏡婦科手術80例,隨機分成瑞芬太尼異丙酚組(RP組)和瑞芬太尼依托咪酯組(RE組),各40例。兩組全麻誘導用藥相同,維持麻醉RP組采用瑞芬太尼聯合異丙酚、RE組采用瑞芬太尼聯合依托咪酯。記錄基礎值、誘導后、插管后1 min、3 min、氣腹時、氣腹后10、20、30、40 min的動脈收縮壓(SBP)、舒張壓(DBP)、心率(HR);記錄停藥至自主呼吸恢復、睜眼、拔除氣管導管、恢復定向能力的時間;記錄清醒即刻及清醒后1、2、4、8、12、16、20、24 h患者疼痛程度,采用VAS評分;記錄24 h內不良反應發生情況。 結果: 兩組SBP、DBP均在誘導后明顯低于基礎值(Plt;001), 插管后恢復,氣腹開始后趨于平穩;兩組HR均在誘導后減慢(Plt;001),插管后及氣腹開始時恢復。RP組自主呼吸恢復、呼之能睜眼、拔除氣管導管及恢復定向能力的時間均明顯短于RE組(Plt;001)。麻醉清醒即刻、清醒后1、2、4、8 h VAS評分RE組明顯低于RP組(Plt;005),12、16、20、24 h VAS評分兩組比較無顯著性差異(Pgt;005)。術后發生惡心嘔吐患者數RP組明顯減少(Plt;005)。 結論:全麻行腹腔鏡婦科手術時,瑞芬太尼聯合異丙酚或依托咪酯都能緩解氣腹及手術引起的血流動力學變化,瑞芬太尼聯合異丙酚術后蘇醒快且能明顯降低術后惡心嘔吐的發生率,但術后疼痛較為嚴重。
ObjectiveTo study the feasibility of using propofol and remifentanil for tracheal intubation in patients who are awake, and investigate the influence of tracheal intubation on such vital signs as blood pressure and heart rates. MethodsEighty ASA I-Ⅱ patients who underwent general anesthesia in our hospital between December 2012 and April 2013 were randomly divided into two groups. Patients in group A received fentanyl-propofol, while patients in group B received remifentanyl-propofol-lidocaine. There was no significant difference between the two groups in gender, age, and body weight (P>0.05). Conventional intubation induction method was used for group A:0.05-0.10 mg/kg midazolam, 4 μg/kg fentanyl, 1.0-1.5 mg/kg propofol, and 0.6-0.9 mg/kg atracurium were given and tracheal intubation was performed after muscle relaxation. Group B patients were treated with remifentanyl propofol-lidocaine compound liquid slow intravenous injection, and compound cricothyroid membrane puncture method before endotracheal intubation. We observed the two groups of patients for vital signs before and after induction, and choking cough reactions. ResultsPatients in both the two groups were all able to complete tracheal intubation. Circulation change and incidence of tachycardia in patients of group A were significantly higher than those in group B (P<0.05). The rates of bradycardia, hypoxemia, and choking cough response were low in both groups with no statistically significant difference (P>0.05). ConclusionRemifentanyl propofol-lidocaine compound liquid can be safely used for implementation of endotracheal intubation in patients who are awake, and the hemodynamic stability can be maintained.
