Background and objectives Postoperative pain after laparoscopic cholecystectomy (LC) is unpredictable, which explains the need for systematic prevention of pain before the patient wakes up from anesthesia. The study was conducted to evaluate the effect of intraperitoneal levobupivacaine with or without sufentanil for postoperative analgesia after LC. Patients and methods Ninety patients who underwent elective LC completed the study. Group C (n=29) received 50 ml of intraperitoneal normal saline, group L (n=31) received 50 ml of intraperitoneal levobupivacaine 0.25%, and group LS (n=30) received 50 ml of intraperitoneal levobupivacaine 0.25% plus 20 μg sufentanil. Visual analog score was recorded immediately postoperatively, and at 4, 8, and 12 h postoperatively. In addition, time to first rescue analgesia (diclofenac), total diclofenac consumption in 12 h, and complications (pruritus, emesis, shoulder pain, bradycardia, and hypotension) were recorded. Results Visual analog score until 8 h postoperatively was significantly higher in group C compared with groups L and LS. However, the difference was nonsignificant between groups L and LS, except at 8 and 12 h postoperatively. Time to first rescue analgesia was significantly longer in group LS (134.16±36.5) compared with group C (11.96±5.92) and group L (114.83±35.49) (P<0.001). Total diclofenac consumption in the first 12 h postoperatively was significantly lower in group L (92.5±32.26) and group LS (82.5±22.88) compared with group C (152.5±13.69). Conclusion Intraperitoneal instillation of levobupivacaine with sufentanil reduces not only the intensity of postoperative pain but also the total rescue analgesic dose consumption after LC.
背景与目的腹腔镜胆囊切除术(LC)术后疼痛是不可预测的,这就解释了在患者从麻醉中醒来之前系统预防疼痛的必要性。本研究旨在评价左布比卡因腹腔内加或不加舒芬太尼用于LC术后镇痛的效果。患者和方法90例接受选择性LC的患者完成了研究。C组(n=29)腹腔注射生理盐水50 ml, L组(n=31)腹腔注射0.25%左布比卡因50 ml, LS组(n=30)腹腔注射0.25%左布比卡因50 ml +舒芬太尼20 μg。术后立即、术后4、8、12小时分别记录视觉模拟评分。此外,记录首次抢救镇痛(双氯芬酸)的时间、12 h内双氯芬酸的总用量、并发症(瘙痒、呕吐、肩痛、心动过缓、低血压)。结果C组术后8 h视觉模拟评分明显高于L组和LS组。然而,除了术后8和12 h外,L组和LS组之间差异无统计学意义。LS组首次抢救镇痛时间(134.16±36.5)明显高于C组(11.96±5.92)和L组(114.83±35.49)(P<0.001)。术后前12 h双氯芬酸总消耗量L组(92.5±32.26)、LS组(82.5±22.88)明显低于C组(152.5±13.69)。结论左布比卡因联合舒芬太尼腹腔注射不仅可减轻术后疼痛强度,而且可减少LC术后抢救镇痛总剂量的消耗。

Background Available medications for the treatment of neuropathic pain, such as steroidal anti-inflammatory drugs and NSAIDs, were shown to be of limited therapeutic benefit. Objectives This study aimed to evaluate the analgesic and anti-inflammatory effects of atorvastatin and pravastatin in acute and neuropathic pain in rats. Materials and methods Acute and neuropathic pains were induced in rat models by means of subplantar carrageenan injection and partial sciatic nerve ligation (PSNL), respectively. The anti-inflammatory effect of statins was assessed by the reduction in plantar edema (at 0, 1, 2, and 3 h) and prolongation of paw withdrawal reaction time in response to thermal stimulation (at 0, 0.5, 1, 2, 3, and 4 h) after carrageenan injection. Atorvastatin (2, 4, or 8 mg/kg) and pravastatin (4, 8, or 12 mg/kg) were administered intraperitoneally 30 min before carrageenan injection. The effect of statins on neuropathic pain was assessed by prolongation of paw withdrawal reaction time in response to thermal stimulation evaluated at 0, 3, 6, 9, 12, 15, and 18 days after PSNL. Atorvastatin (2, 4, or 8 mg/kg) and pravastatin (4, 8, or 12 mg/kg) were administered orally for 18 consecutive days after PSNL. In addition, the effect of atorvastatin and pravastatin on total cholesterol and tumor necrosis factor-α levels was also assessed. Results Both atorvastatin and pravastatin ameliorated carrageenan-induced rat paw edema and prolonged withdrawal time in response to thermal-induced pain. Both statins were also effective in ameliorating neuropathic pain induced by PSNL. These effects were independent of statin-induced hypolipidemic action but were concomitant with reduction of serum tumor necrosis factor-α levels. Conclusion Atorvastatin and pravastatin demonstrated effective therapeutic potentials to reduce acute and chronic pain together with the associated inflammation and hyperalgesia independent of their hypolipidemic effect.
研究背景:用于神经性疼痛治疗的现有药物,如甾体抗炎药和非甾体抗炎药,疗效有限。目的观察阿托伐他汀和普伐他汀对急性和神经性疼痛大鼠的镇痛和抗炎作用。材料与方法采用卡拉胶足底注射法和部分坐骨神经结扎法分别诱导大鼠急性痛和神经性痛。他汀类药物的抗炎作用是通过观察卡拉胶注射后足底水肿(0、1、2和3小时)的减少以及热刺激(0、0.5、1、2、3和4小时)下足部退出反应时间的延长来评估的。阿托伐他汀(2、4或8 mg/kg)和普伐他汀(4、8或12 mg/kg)在卡拉胶注射前30分钟腹腔注射。在PSNL后0、3、6、9、12、15和18天,他汀类药物对神经性疼痛的影响通过延长热刺激下的足部戒断反应时间来评估。PSNL后连续18天口服阿托伐他汀(2、4或8 mg/kg)和普伐他汀(4、8或12 mg/kg)。同时观察阿托伐他汀和普伐他汀对总胆固醇和肿瘤坏死因子-α水平的影响。结果阿托伐他汀和普伐他汀均能改善卡拉胶诱导的大鼠足部水肿,延长热致疼痛戒断时间。这两种他汀类药物在改善PSNL引起的神经性疼痛方面也有效。这些作用与他汀类药物诱导的降血脂作用无关,但与血清肿瘤坏死因子-α水平的降低同时发生。结论阿托伐他汀和普伐他汀可有效减轻急性和慢性疼痛及相关炎症和痛觉过敏,但不影响其降血脂作用。

Background Radiofrequency ablation (RFA) is a minimally invasive and effective method for local tumor destruction in nonsurgical patients with early-stage hepatocellular carcinoma (HCC). General anesthesia (GA) has been used for RFA. GA can decrease the hepatic blood flow and cause more hepatic dysfunction. This study aimed to compare the hemodynamic response, recovery characteristics, and postprocedural analgesia after induction of GA with either sevoflurane–propofol or sevoflurane–ketofol in liver patients undergoing RFA of HCC. Patients and methods Eighty patients with hepatic cirrhosis scheduled for RFA of HCC were randomly allocated into two groups. In group PS, induction of anesthesia was achieved using sevoflurane with propofol (1%). In group KPS, induction of anesthesia was achieved using sevoflurane with ketofol (prepared at a ratio of 1: 2). Results Regarding the induction time, the laryngeal mask airway (LMA) insertion time, the percentage of LMA insertions from the first attempt, time to removal of LMA, and time to emergence were comparable between the two groups. However, the rescue analgesia time was longer in group KPS compared with group PS (P < 0.001). The number of episodes during which blood pressure was below 20% of baseline blood pressure, as well as the highest and the lowest mean arterial pressure, was comparable between the two groups. Postoperative levels of liver enzymes were comparable between the two groups. In the recovery unit, only one patient (2.5%) in group KPS suffered from postoperative emergence agitation, and three patients (7.5%) suffered from nausea. Conclusion Either sevoflurane–propofol or sevoflurane–ketofol may be used as alternatives in liver patients undergoing RFA of HCC as both techniques have favorable anesthetic profiles and provide hemodynamic stability. However, when choosing sevoflurane–ketofol, the advantage of its enhanced analgesic effect must be weighed against the increased risk for postoperative nausea and vomiting.
背景射频消融术(RFA)是一种微创、有效的治疗早期肝细胞癌(HCC)的方法。全麻(GA)已被用于RFA。GA可减少肝血流量,加重肝功能障碍。本研究旨在比较七氟醚-异丙酚或七氟醚-酮酚在肝细胞癌RFA患者中诱导GA后的血流动力学反应、恢复特征和术后镇痛。患者与方法80例肝硬化肝细胞癌RFA患者随机分为两组。PS组采用七氟醚与异丙酚(1%)诱导麻醉。KPS组采用七氟醚与酮酚(按1:2的比例配制)诱导麻醉。结果两组在诱导时间、喉罩气道(LMA)插入时间、第一次喉罩气道插入百分比、喉罩气管取出时间和出现时间方面具有可比性。但KPS组抢救镇痛时间较PS组长(P < 0.001)。血压低于基线血压20%的发作次数以及最高和最低的平均动脉压在两组之间具有可比性。两组术后肝酶水平相当。在恢复单元中,KPS组仅有1例(2.5%)患者出现术后涌现性躁动,3例(7.5%)患者出现恶心。结论七氟醚-异丙酚或七氟醚-酮酚均可作为肝细胞癌RFA患者的替代方案,两种技术均具有良好的麻醉效果和血流动力学稳定性。然而,在选择七氟酮酚时,必须权衡其增强镇痛效果的优势与术后恶心和呕吐风险的增加。

Objectives The aim of this study was to compare the effect of sevoflurane general anesthesia (GA) and sciatic–femoral–obturator blockade as regards analgesia and incidence of postoperative cognitive dysfunction (POCD) in elderly patients undergoing unilateral total knee replacement. Patients and methods The patients were divided in a randomized manner into two groups: the GA group (n=40) received maintenance of anesthesia with inhalational sevoflurane, and the peripheral nerve block (PNB) group (n=40) underwent sciatic nerve block (40 ml), femoral nerve block (20 ml), and obturator nerve block (10 ml) with 0.25% bupivacaine. The following time points were considered: baseline, immediately before induction of anesthesia (T-baseline), immediately after induction of anesthesia (T-induction), at the end of the operation (T-end) and then at 6, 12, 18, and 24 h postoperatively and were represented as T6, T12, T18, and T24, respectively. Results A total of 15 of 40 patients from the GA group developed POCD, whereas six of 38 patients in the PNB group developed POCD at T24. This difference was significant. Moreover, there was a significant decrease in Mini-Mental State Examination score in the GA group after 24 h in comparison with the preoperative value. There was a significantly higher value of Aβ (β-amyloid protein) in the GA group compared with the PNB group 24 h postoperatively. Visual analogue score was significantly lower at T-end, T6, T12, T18, and T24 in the PNB group compared with the GA group. Hemodynamics was significantly lower in the PNB group than in the GA group at T-end, T6, T12, T18, and T24. They were significantly higher in the PNB group than in the GA group at T-induction. Total opioid consumption within 24 h postoperatively and the incidence of nausea were lower in the PNB group compared with the GA group. Induction time was significantly longer in the PNB group than in the GA group. Conclusion The current study demonstrated that PNB with sciatic–femoral–obturator for total knee replacement was accompanied by less POCD, less pain, less nausea, and less opioid consumption within 24 h postoperatively compared with GA with sevoflurane.
目的:比较七氟醚全麻(GA)和坐骨-股-闭孔阻滞对老年单侧全膝关节置换术患者镇痛和术后认知功能障碍(POCD)发生率的影响。患者和方法将患者随机分为两组:GA组(n=40)采用吸入性七氟醚维持麻醉,周围神经阻滞(PNB)组(n=40)采用0.25%布比卡因坐骨神经阻滞(40 ml)、股神经阻滞(20 ml)和闭孔神经阻滞(10 ml)。考虑以下时间点:基线、麻醉诱导前(T-baseline)、麻醉诱导后(T-induction)、手术结束(T-end)和术后6、12、18、24 h,分别用T6、T12、T18、T24表示。结果GA组40例患者中有15例发生POCD,而PNB组38例患者中有6例在T24发生POCD。这种差异是显著的。此外,GA组24 h后精神状态检查评分较术前有显著下降。术后24 h GA组β-淀粉样蛋白含量明显高于PNB组。PNB组t端、T6、T12、T18、T24的视觉模拟评分明显低于GA组。PNB组在t端、T6、T12、T18、T24的血流动力学明显低于GA组。t诱导时,PNB组明显高于GA组。与GA组相比,PNB组术后24 h内阿片类药物总消耗量和恶心发生率均较低。PNB组诱导时间明显长于GA组。结论目前的研究表明,与加七氟醚的全膝关节置换术相比,经坐骨-股-闭孔的PNB术后24 h内POCD、疼痛、恶心和阿片类药物消耗更少。

Background Regional anesthesia is the technique of choice for patients undergoing transurethral resection of the prostate (TURP), but anesthetic management of elderly patients is challenging due to compromised organ function. The present study aimed to evaluate the relative efficacy and safety of dexmedetomidine versus fentanyl in the enhancement of the quality and duration of epidural anesthesia with 0.5% levobupivacaine and hemodynamic stability during TURP in elderly patients. Patients and methods Sixty elderly consented patients were randomized into two equal groups of 30 patients each in a double-blind manner. They were given 15 ml of 0.5% levobupivacaine (75 mg) either with 1 ml (50 μg) dexmedetomidine (group LD) or with 1 ml (50 μg) fentanyl (group LF) using an epidural catheter. The primary endpoints were the onset and duration of sensory and motor blockade, duration of sensory analgesia, hemodynamic variability, respiratory adequacy, and any adverse effect. Results Demographic data were comparable in both groups. Onset of sensory and motor blockade was faster in patients of group LD than in patients of group LF, with a statistically significant difference (P < 0.05). Duration of motor blockade and sensory analgesia was longer in patients of group LD than in patients of group LF (P < 0.05). Intraoperative heart rate and mean arterial blood pressure were significantly lower in patients of group LD, but no intervention was required. Surgical bleeding was reduced in patients of group LD. Conclusion Dexmedetomidine as an adjuvant to epidural levobupivacaine for TURP has shortened onset time of anesthesia and prolonged duration of sensory analgesia. The surgical field vision was improved due to reduced bleeding.
背景区域麻醉是经尿道前列腺切除术(TURP)患者的首选技术,但由于器官功能受损,老年患者的麻醉管理具有挑战性。本研究旨在评价右美托咪定与芬太尼在提高0.5%左布比卡因硬膜外麻醉质量和持续时间以及老年患者TURP期间血流动力学稳定性方面的相对有效性和安全性。患者与方法采用双盲方法,将60例老年患者随机分为两组,每组30例。经硬膜外导管给予15 ml 0.5%左布比卡因(75 mg)与1 ml (50 μg)右美托咪定(LD组)或1 ml (50 μg)芬太尼(LF组)。主要终点是感觉和运动阻断的开始和持续时间,感觉镇痛的持续时间,血流动力学变异性,呼吸充分性和任何不良反应。结果两组人口统计学数据具有可比性。LD组感觉及运动阻滞发作速度快于LF组,差异有统计学意义(P < 0.05)。LD组运动阻滞和感觉镇痛持续时间明显长于LF组(P < 0.05)。LD组患者术中心率和平均动脉血压明显降低,但不需要干预。结论右美托咪定辅助硬膜外左布比卡因治疗TURP可缩短麻醉起效时间,延长感觉镇痛时间。手术视野因出血减少而改善。

Analysis of ventilator graphics is useful in a few situations for detecting ventilator dysfunction. However, there is a paucity of literature as to what sort of dysfunctions can be detected. We report two cases in which the graphics enabled us to identify ventilator dysfunction in patients who were on mechanical ventilation. Analysing the graphics and not looking at numbers alone enabled us to take timely corrective actions, thereby preventing morbidity. Both patients ultimately achieved a complete recovery.
通风机图形分析在检测通风机功能障碍的一些情况下是有用的。然而,关于可以检测到哪种功能障碍的文献很少。我们报告了两个病例,其中图形使我们能够识别机械通气患者的呼吸机功能障碍。分析图表而不是仅仅看数字使我们能够及时采取纠正措施,从而防止发病率。两位病人最终都完全康复了。

Background Septic shock is one of the biggest causes of mortality in intensive care settings, and, despite all the recent advances in pharmacological and mechanical support therapies, is the second leading cause of death among ICU patients. Although vasopressors have been widely used in these situations, where keeping the hemodynamic stability is of utmost importance, a detailed study of their effects is undoubtedly needed. Objective Our study compared the effect of methylene blue (MB) in the vasoplegic situation associated with sepsis with that of vasopressin. Patients and methods We randomized 40 patients into two groups (20 patients each); patients in the first group received MB, whereas patients in the second group received vasopressin as a hemodynamic support. Results In the present study, mean arterial blood pressure was found to be significantly higher in the MB group compared with the vasopressin group, whereas within the MB group, it was significantly higher after 6 h compared with the baseline level. The systemic vascular resistance showed no difference between the two groups at the start but a marked difference only after 2 h, being higher for the MB group — that is, there was a significant decrease in the vasopressors and inotropes needed in the MB group. There was no significant difference between the two groups regarding the ICU length of stay, the central venous pressure, pulmonary artery pressure, and oxygen extraction ratio. Conclusion The use of MB in sepsis-induced refractory vasoplegic situations remains one of the salvage management strategies; however, the practice of its routine use is yet to be established and needs further investigation.
背景:脓毒性休克是重症监护室死亡的最大原因之一,尽管最近在药理学和机械支持治疗方面取得了进展,但它是ICU患者死亡的第二大原因。尽管血管加压剂已被广泛应用于这些情况,在这些情况下,保持血流动力学稳定性是至关重要的,但对其作用的详细研究无疑是必要的。目的比较亚甲基蓝(MB)在脓毒症合并血管瘫痪情况下与加压素的疗效。患者与方法40例患者随机分为两组(每组20例);第一组患者接受MB治疗,而第二组患者接受血管加压素作为血流动力学支持。结果在本研究中,MB组的平均动脉血压明显高于抗利尿激素组,而MB组在6小时后的平均动脉血压明显高于基线水平。两组的全身血管阻力在开始时没有差异,但只有在2小时后才有明显差异,MB组更高-即MB组所需的血管加压剂和肌力明显减少。两组患者在ICU的住院日、中心静脉压、肺动脉压、吸氧率均无显著差异。结论在脓毒症引起的难治性血管截瘫中应用MB仍是抢救治疗策略之一;然而,其常规使用的做法尚未确定,需要进一步调查。

Objective The aim of the present study was to detect the efficacy of early postoperative calf muscle exercise to decrease the risk of deep venous thrombosis achieved by intrathecal 3 ml bupivacaine 0.25% and fentanyl 25 μg instead of 3 ml bupivacaine 0.5%. In total, 40 patients of either sex, aged between 18 and 60 years, with American Society of Anesthesiologists (ASA) I and II were included in the study. Patients and methods A total of 40 ASA I and II patients undergoing elective total hip replacement surgery were randomly assigned to two equal groups of 20 patients each (group A and B). Group A received bupivacaine 0.5% (3 ml) and group B received bupivacaine 0.25% (3 ml)+fentanyl 25 μg. Patients were instructed on how to do cuff muscle exercise once they regained the full strength of the lower limbs muscles postoperatively. Five venous blood samples were taken from each patient for the D-dimer assessment as an indicator for the occurrence of venous thromboembolism. The first sample was taken preoperatively at the time of induction of anesthesia; the rest of samples were then taken at 12, 24, 48 h, and 7 days postoperatively. Results Group B, in which patients received intrathecal bupivacaine 0.25% plus fentanyl, had an earlier recovery of motor power; patients in this group started doing calf muscle exercise earlier than did those in group A, and this group had significantly lower postoperative D-dimer level, denoting less susceptibility to deep venous thrombosis. Conclusion Early postoperative calf muscle exercise decreased the incidence of venous thromboembolism risk as indicated by the results of the D-dimer assessment.
目的观察用0.25%布比卡因3 ml,芬太尼25 μg代替0.5%布比卡因3 ml,术后早期进行小腿肌肉运动对降低深静脉血栓形成风险的效果。共有40名患者,年龄在18岁至60岁之间,均为美国麻醉师学会(ASA) I和II级。患者和方法选择ASA I、II期择期全髋关节置换术患者40例,随机分为两组,每组20例(A组和B组),A组给予0.5%布比卡因(3 ml), B组给予0.25%布比卡因(3 ml)+芬太尼25 μg。指导患者在术后恢复下肢肌肉的全部力量后如何进行袖带肌肉锻炼。从每位患者抽取5份静脉血样本进行d -二聚体评估,作为静脉血栓栓塞发生的指标。第一次取样于术前诱导麻醉时;其余标本分别于术后12、24、48小时和7天采集。结果B组患者鞘内注射0.25%布比卡因加芬太尼,运动能力恢复较早;该组患者开始进行小腿肌肉锻炼的时间较A组早,术后d -二聚体水平明显降低,对深静脉血栓形成的易感性较低。结论d -二聚体评估结果表明,术后早期小腿肌肉运动可降低静脉血栓栓塞的发生率。

Vasopressin, a potent vasoconstrictor, has often been used intramyometrially to prevent blood loss during surgical management of uterine myomas. Various lethal complications reported with its use include bradycardia, unmeasurable blood pressure, loss of palpable peripheral pulse, marked pallor, arrhythmia, pulmonary oedema and cardiac arrest. We herein report a case of uterine myomas in which intramyometrial vasopressin-induced complications such as bradycardia, absent pulse and marked pallor were observed with very low dose and concentration (i.e. 1.5 U and 0.1 U/ml). This could be attributed to the coexistence of hypertension in our patient. Here, we discuss the anaesthetic concerns with the use of intramyometrial vasopressin and reinforce the need for dogmatic guidelines envisaging the recommended safe dose and concentrations of intramyometrial vasopressin and proper patient selection.
垂体后叶加压素是一种有效的血管收缩剂,在子宫肌瘤手术治疗过程中经常被用于子宫肌内防止失血。据报道,使用该药的各种致命并发症包括心动过缓、无法测量血压、周围脉搏消失、明显苍白、心律失常、肺水肿和心脏骤停。我们在此报告一例子宫肌瘤,在子宫内膜内抗利尿激素引起的并发症,如心动过缓,脉搏消失和明显苍白,在非常低的剂量和浓度(即1.5 U和0.1 U/ml)。这可能与患者同时存在高血压有关。在这里,我们讨论了使用子宫内膜内抗利尿激素的麻醉问题,并强调了对子宫内膜内抗利尿激素推荐安全剂量和浓度以及适当患者选择的教条式指导的必要性。

Background The use of magnesium sulfate as an adjuvant in neuraxial block has gained popularity, with the aim of improving and enhancing the quality and duration of anesthesia, delaying the onset of postoperative pain, and thus reducing the demand for postoperative rescue analgesics. However, until today, there has been no consensus as regards the ideal dose of magnesium sulfate as an adjuvant in the subarachnoid block. The present study was designed to examine whether the addition of intrathecal magnesium sulfate (50 and 100 mg) would enhance the analgesic efficacy of intrathecal bupivacaine. We hypothesized that the additive effect of magnesium sulfate as an adjuvant to bupivacaine in subarachnoid block is dose dependent. Materials and methods This study was carried out on 90 American Society of Anesthesiology I and II patients of both sexes in the age group of 20–60 years scheduled for below knee surgeries under subarachnoid block. Group 1 (n = 30) patients received intrathecal 0.5% heavy bupivacaine (2.8 ml) +0.2 ml normal saline; group 2 (n = 30) received intrathecal 0.5% heavy bupivacaine (2.8 ml) +50 mg (0.1 ml) magnesium sulfate +0.1 ml normal saline; and group 3 (n = 30) received intrathecal 0.5% heavy bupivacaine (2.8 ml)+100 mg (0.2 ml) magnesium sulfate. The primary outcome measure was the duration of postoperative analgesia, and secondary outcomes included the number of supplemental analgesic requirements, block characteristics, and hemodynamic stability. Results The onset of sensory and motor block was delayed in the magnesium group (100 mg>50 mg). There was a significant prolongation of postoperative analgesia in the magnesium group in a dose-dependent manner, and total dose of rescue analgesic requirement was found to be significantly delayed in the 100 mg group. Patients in all groups remained hemodynamically stable without any adverse effects. Conclusion Magnesium sulfate (100 mg) as an adjuvant to bupivacaine in subarachnoid block prolongs the duration of analgesia and decreases the demand for rescue analgesics compared with the control and the magnesium sulfate 50 mg group.
背景硫酸镁作为神经轴阻滞的辅助用药已得到广泛应用,其目的是改善和提高麻醉质量和麻醉时间,延缓术后疼痛的发生,从而减少术后抢救镇痛药的需求。然而,直到今天,关于硫酸镁作为蛛网膜下腔阻滞佐剂的理想剂量还没有达成共识。本研究旨在探讨鞘内添加硫酸镁(50和100 mg)是否会增强鞘内布比卡因的镇痛效果。我们假设硫酸镁作为布比卡因在蛛网膜下腔阻滞中的辅助剂的加性作用是剂量依赖性的。材料与方法本研究选取了90例年龄在20 ~ 60岁的美国麻醉学学会I、II级患者,男女均为,拟行蛛网膜下腔阻滞下膝下手术。第一组(n = 30)患者鞘内注射0.5%重布比卡因(2.8 ml) +0.2 ml生理盐水;2组(n = 30)鞘内注射0.5%重布比卡因(2.8 ml) +50 mg硫酸镁(0.1 ml) +生理盐水0.1 ml;第三组(n = 30)鞘内注射0.5%重布比卡因(2.8 ml)+硫酸镁100 mg (0.2 ml)。主要结局指标是术后镇痛持续时间,次要结局包括补充镇痛需求的次数、阻滞特征和血流动力学稳定性。结果镁组(100 mg>50 mg)感觉和运动阻滞的发生时间明显延迟。镁组患者术后镇痛时间明显延长,且呈剂量依赖性,100 mg组患者术后镇痛总需要剂量明显延迟。各组患者血流动力学稳定,无不良反应。结论与对照组和硫酸镁50 mg组相比,硫酸镁100 mg作为布比卡因蛛网膜下腔阻滞的辅助剂可延长镇痛时间,减少对抢救镇痛药物的需求。
