Remifentanil added to sufentanil-sevoflurane anesthesia suppresses hemodynamic and metabolic stress responses to intense surgical stimuli more effectively than high-dose sufentanil-sevoflurane alone.

ABSTRACT:

Background

Even extremely high-doses of the potent opioid, sufentanil, cannot reliably suppress stress responses to intense surgical stimuli such as sternotomy. The chemically related opioid remifentanil with its different pharmacokinetics and binding affinities for delta- and kappa-opioid receptors might be more effective in attenuating these responses.

Methods

ASA I-III patients scheduled for a surgical procedure with sternotomy under balanced anesthesia (sevoflurane and sufentanil 3 ?g.kg(-1) bolus, 0.017 ?g.kg(-1).min(-1) infusion) were randomized into two groups. Patients in the study group were supplemented with remifentanil (2 ?g.kg(-1) bolus, 2-7 ?g.kg(-1).min(-1) infusion) starting ten minutes before sternotomy. Heart rate, arterial blood pressures, cardiac index, ejection fraction, systemic vascular resistance index (SVRI), total body oxygen uptake (VO2) and electric dermal response were measured and compared between the groups.

Results

62 patients were studied (study group 32, control group 30). Systolic and mean arterial blood pressures, SVRI, VO2 and skin conductance increased during sternotomy and sternal spread in the control group but not in the study group. Systolic blood pressure increase: 7.5?±?19 mmHg vs. -3.4?±?8.9 (p?=?0.005); VO2 increase: 31?±?46% vs. -0.4?±?32%; incidence of systolic blood pressure increase greater than 15 percent: 20% vs. 3% (p?=?0.035) (control vs. study group).

Conclusion

High-dose remifentanil added to sevoflurane-sufentanil anesthesia suppresses the sympathoadrenergic response to sternotomy and sternal spread better than high-dose sufentanil alone.

Project description:BackgroundIntravenous use of sufentanil can elicit cough. This study aimed to evaluate the inhibitory effect of pre-injection of a mall dose of remifentanil on sufentanil-induced cough during the induction of general anesthesia.MethodsThis prospective, randomized, controlled trial was conducted from January 10, 2019 to March 01, 2019. A total of 100 patients undergoing elective surgery under general anesthesia were enrolled, and at last 84 patients were included and randomly allocated into two equal size groups (n =?42): Patients in the Remifentanil group (R group) received an intravenous infusion of remifentanil 0.3??g/kg (diluted to 2?ml) 1?min before sufentanil injection; patients in the Control group (C group) received 2?ml of normal saline (NS) at the same time point. Injections of patients in both groups were completed within 5?s. Then, sufentanil 0.5??g/kg was injected within 5?s and the number of coughs that occurred within 1?min after sufentanil injection were recorded. One minute after sufentanil injection, etomidate 0.3?mg/kg and cisatracurium 0.15?mg/kg were given for general anesthesia induction irrespective of the presence or absence of cough. The mean arterial pressure (MAP) and heart rate (HR) at time points just before remifentanil pretreatment administration (T0), 3?min after administration (T1), 1?min after intubation (T2), and 3?min after intubation (T3) were recorded.ResultsThe incidence of cough in patients in the R group and C group was 4.8 and 31%, respectively. Compared with group C, the incidence and severity of cough in group R was significantly lower (P <?0.01). No significant differences were observed in MAP and HR at the time of general anesthesia induction between the two groups (P >?0.05).ConclusionPretreatment with a small dose of remifentanil effectively and safely reduced the incidence and severity of cough induced by sufentanil during anesthesia induction and can be used as an alternative treatment to inhibit coughing caused by sufentanil.Trial registrationChinese Clinical Trial Registry (ChiCTR1900020587, registered date: January 9, 2019), http://www.chictr.org.cn.

Project description:The aim of the present study was to observe whether dexmedetomidine (DEX) combined with sufentanil decreased emergence agitation (EA) in children receiving sevoflurane anesthesia for cleft palate repair surgery. Children undergoing elective cleft palate repair surgery were randomly allocated into the DEX + sufentanil group (group DS; n=50) and the normal saline + fentanyl group (group SF; n=50). Patients in group DS were treated with 0.5 µg/kg DEX prior to induction of anesthesia, whereas patients in group SF received an equal volume of normal saline. Sufentanil (0.2 µg/kg) was administered to induce anesthesia, and 30 min before the end of surgery for patients in group DS. Fentanyl (2 µg/kg) was administered at the same time point for patients in group SF. Mean arterial pressure (MAP), heart rate (HR), duration of surgery and anesthesia, and the dosage of remifentanil were assessed. EA score, Pediatric Anesthesia Emergence Delirium (PAED) score and the Children and Infants Postoperative Pain Scale (CHIPPS) score were documented every 15 min in the post-anesthesia care unit (PACU). The number of cases requiring fentanyl (1 µg/kg) and the recovery profile data were analyzed. Compared with group DS (P<0.05) and the baseline (P<0.05), HR and MAP were significantly increased in group SF immediately following tracheal intubation and extubation. Mean values of maximum EA, PAED and CHIPPS scores were significantly reduced in group DS compared with group SF at 0 (P<0.01), 15 (P<0.05), and 30 min (P<0.05) after arrival at PACU. The incidence of EA in group SF was significantly increased compared with group DS (P<0.05). The dosage of remifentanil during the surgery and the number of cases requiring fentanyl (1 µg/kg) in group DS were significantly decreased compared with group SF (P<0.05). The findings of the present study suggested that DEX combined with sufentanil was able to effectively decrease the incidence of EA in children receiving sevoflurane anesthesia for cleft palate repair surgery.

Project description:OBJECTIVE:The addition of lipophilic opioids to local anesthetics for spinal anesthesia has become a widely used strategy for cesarean anesthesia. A meta-analysis to quantify the benefits and risks of combining sufentanil with bupivacaine for patients undergoing cesarean delivery was conducted. METHODS:A comprehensive literature search without language or date limitation was performed to identify clinical trials that compared the addition of sufentanil to bupivacaine with bupivacaine alone for spinal anesthesia in healthy parturients choosing cesarean delivery. The Q and I2 tests were used to assess heterogeneity of the data. Data from each trial were combined using relative ratios (RRs) for dichotomous data or weighted mean differences (WMDs) for continuous data and corresponding 95% confidence intervals (95% CIs) for each trial. Sensitivity analysis was conducted by removing one study a time to assess the quality and consistency of the results. Begg's funnel plots and Egger's linear regression test were used to detect any publication bias. RESULTS:This study included 9 trials containing 578 patients in the final meta-analysis. Sufentanil addition provided a better analgesia quality with less breakthrough pain during surgery than bupivacaine alone (RR = 0.10, 95% CI 0.06 to 0.18, P < 0.001). Sensory block onset time was shorter and first analgesic request time was longer in sufentanil added group compared with the bupivacaine-alone group (WMD = -1.0 min, 95% CI -1.5 to -0.58, P < 0.001 and WMD = 133 min, 95% CI 75 to 213, P < 192, respectively). There was no significant difference in the risk of hypotension and vomiting between these two groups. But pruritus was more frequentely reported in the group with sufentanil added (RR = 7.63, 95% CI 3.85 to 15.12, P < 0.001). CONCLUSION:Bupivacaine and sufentanil combination is superior to that of bupivacaine alone for spinal anesthesia for cesarean delivery in analgesia quality. Women receiving the combined two drugs had less breakthrough pain, shorter sensory block onset time, and longer first analgesic request time. However, the addition of sufentanil to bupivacaine increased the incidence of pruritus.
