Abstract: Introduction: since ancient times opioids have been part of anesthesia. The development of new drugs based on the piperidine class prototype fentanyl has resulted in more potent and specific opioids. One such example is sufentanil. Sufentanil is presented as a further option for perioperative anesthetic management in different clinical scenarios from general anesthesia to sedation or critical care. Its wide therapeutic range, analgesic potency and predictable adverse effects make it a comparable or superior option to other opioids like fentanyl. The dosage recommended by the FDA and other sources are broad but in a wide variety of situations opting for the minimum effective dosage is the most recommended. Objective: a review of the pharmacokinetic and pharmacodynamic aspects of sufentanil, its applications and recommendations based on literature and clinical practice. To spread knowledge of the clinical use of sufentanil in order to promote a change in the classical paradigm of opioid use in anesthesia. Conclusions: Sufentanil is one of the best options for pain management in different clinical scenarios, from short-term procedures such as sedations to highly complex surgeries, its pharmacokinetic profile very similar to fentanyl, with a wide therapeutic margin and greater analgesic potency, make it a more than adequate option for contemporary anesthetic practice.
ABSTRACT
Objective To compare the application effects of low-dose esketamine and sufentanil on perioperative analgesia in patients undergoing hip arthroplasty(HA).Methods A total of 124 patients who underwent HP in our hospital were divided into the control group and the observation group according to random number table,with 62 cases in each group.Patients in the control group were given sufentanil for analgesia,and patients in the observation group were given low-dose esketamine for analgesia.The hemodynamics changes of the heart rate(HR),respiratory rate(RR),mean arterial pressure(MAP)and oxygen saturation(SpO2)of patients before anesthesia(T1),at the time of incising skin(T2),after 30 minutes of anesthesia(T3)and at the end of surgery(T4)in both groups were observed.The visual analogue scale(VAS)scores of patients in resting state and active state before surgery(T5),6 hours after surgery(T6),12 hours after surgery(T7)and 24 hours after surgery(T8)were recorded.The number of postoperative analgesic pump compression,need of supplemental analgesic drugs and occurrence of adverse reactions during surgery and 24 hours after surgery of patients in the two groups were recorded.Results There was no statistically significant difference in HR,MAP or RR at T1 of patients between the two groups(P>0.05).The levels of HR,MAP and RR at T2,T3 and T4 of patients in the observation group were higher than those in the control group(P<0.05).There was no statistically significant difference in SpO2 at each time points between the two groups(P>0.05).There was no statistically significant difference in the VAS scores at T5 of patients in resting state or active state(P>0.05).The VAS scores at T6,T7 and T8 of patients in resting state and active state in the observation group were lower than those in the control group(P<0.05).The number of postoperative analgesic pump compression and the proportion of patients with the need of supplemental analgesic drugs in the observation group were less/lower than those in the control group(P<0.05).There was no statistically significant difference in the incidence of intraoperative and postoperative adverse reactions of patients between the two groups(P>0.05).Conclusion Compared with sufentanil,low-dose esketamine has better analgesic effect for IA patients,with milder perioperative pain degree,more stable intraoperative hemodynamics,and better safety.
ABSTRACT
Objective To evaluate the effects of ketamine combined with sufentanil on postoperative analgesia and depression in patients undergoing hip arthroplasty.Methods A total of 60 patients who underwent elective hip arthroplasty were selected and divided into the S group,the SK1 group and the SK2 group according to the patient-controlled intravenous analgesia regimen,with 20 cases in each group.Patients in the S group were received 2 μg/kg of sufentanil for postoperative analgesia,patients in the SK1 group were received 1 mg/kg of esketamine and 2 μg/kg of sufentanil for postoperative analgesia,and patients in the SK2 group were received 2 mg/kg of esketamine and 2 μg/kg of sufentanil for postoperative analgesia.At 1,4,24,and 48 hours after surgery,the analgesic effect of patients was evaluated using the numeric rating scale(NRS),and the sedation effect of patients was evaluated using the Ramsay sedation score.Depression of patients before and 48 hours after surgery was assessed by self-rating depression scale(SDS).The adverse reactions such as nausea and vomiting,dizziness and headache,respiratory depression,and mental symptoms within 48 hours after surgery of patients were recorded.Results The NRS scores 1,4,and 24 hours after surgery of patients in the SK1 group and the SK2 group were lower than those in the S group(P<0.05);there was no statistically significant difference in the NRS scores 48 hours after surgery of patients among the three groups(P>0.05);there was no statistically significant difference in the NRS scores at different postoperative points of patients between the SK1 and SK2 groups(P>0.05).The SDS scores 48 hours after surgery of patients in each group were lower than those before surgery(P<0.05).There was no statistically significant difference in the Ramsay scores at different postoperative points of patients among the three groups(P>0.05).The incidence of adverse reactions 48 hours after surgery in the SK2 group was higher than those in the S group and the SK1 group(P<0.05).Conclusion Using 1 mg/kg of esketamine combined with 2 μg/kg of sufentanil after hip arthroplasty has a good analgesic effect without obvious increase of adverse reactions or significant effect on improving depression of patients.
ABSTRACT
Objective To investigate the impacts of Nalbuphine combined with Sufentanil on postoperative analgesia and stress response in patients undergoing laparoscopic colorectal cancer surgery.Methods 86 patients who underwent laparoscopic colorectal cancer surgery from August 2020 to April 2022 were collected and grouped into an experimental group and a control group according to the analgesic plan,with 43 patients in each group.The control group was given Sufentanil after surgery,and the experimental group was given Nalbuphine + Sufentanil.The analgesic and sedative effects at different time points after surgery(1,6,12,24 and 48 h),and the changes in serum pain mediator and stress response indicators were observed and compared.The time of getting out of bed after surgery,the number of patient-controlled analgesia,the number of cases of remedial analgesia,the recovery of gastrointestinal function,and the occurrence of adverse reactions within 48 hours after surgery were recorded in both groups.Results Compared with the control group,the experimental group had a shorter time to get out of bed for the first time after surgery(t = 3.29,P = 0.001),and had fewer instances of patient-controlled analgesia(Z = 4.53,P = 0.000)and cases of remedial analgesia(χ2 = 4.48,P = 0.034);Postoperative 12,24 and 48 h after surgery,the visual analogue scale(VAS)in the experimental group was obviously lower than that in the control group(t = 2.86,t = 2.55,t = 0.10,P<0.05);Postoperative 1 and 6 h,the Ramsay sedation score in the experimental group patients was lower than that in the control group(t = 2.10,t = 2.07,P<0.05);Postoperative 6,12 and 24 h,the serum substance P(SP)(t = 3.63,t = 5.51,t = 3.46,P<0.05)and prostaglandin E2(PGE2)(t = 2.34,t = 3.56,t = 0.33,P<0.05)levels in the experimental group were obviously lower than those in the control group;Postoperative 6,12 and 24 h,the serum cortisol(Cor)level in the experimental group was obviously lower than that in the control group(t = 4.65,t = 6.50,t = 6.52,P<0.05);Postoperative 6,12,24 and 48 h,the serum norepinephrine(NE)(t = 5.49,t = 7.85,t = 7.70,t = 2.18,P<0.05),tumor necrosis factor-α(TNF-α)(t = 5.43,t = 7.83,t = 5.27,t = 2.32,P<0.05),and hypersensitivity C-reactive protein(hs-CRP)(t = 3.39,t = 9.241,t = 4.87,t = 2.37,P<0.05)levels in the experimental group were obviously lower than those in the control group.There was no statistically obvious difference between the two groups in terms of postoperative exhaust time,defecation time,bowel sounds occurrence time,and incidence of adverse reactions(P>0.05).Conclusion Nalbuphine combined with Sufentanil is effective in postoperative analgesia of laparoscopic colorectal cancer patients,and can effectively regulate the post-traumatic stress response of the body after surgery.
ABSTRACT
Objective:To investigate the effects of low-dose ropivacaine combined with sufentanil on the onset time of anesthesia and postoperative rectal traction reflectance in patients undergoing mixed hemorrhoid surgery.Methods:A total of 96 patients who underwent mixed hemorrhoid surgery at the General Hospital of the Southern Theater Command of the Chinese People′s Liberation Army from January 2020 to June 2021 were selected. They were randomly divided into a control group and an observation group using a random number table method, with 48 cases in each group. The control group was anesthetized with low-dose ropivacaine; The observation group was anesthetized with low-dose ropivacaine combined with sufentanil. The anesthesia effect, hemodynamic changes, pain score, bleeding score, postoperative rectal traction reflectance, and incidence of adverse reactions were compared between two groups of patients.Results:Compared with the control group, the observation group had a shorter onset time of anesthesia ( P<0.05) and a longer duration of anesthesia maintenance ( P<0.05). Before surgery, there was no statistically significant difference in heart rate and mean arterial pressure between the two groups of mixed hemorrhoid patients (all P>0.05); After surgery, both groups of patients had an increase in heart rate, a decrease in mean arterial pressure, and a more significant change in the control group (all P<0.05). Before surgery, there was no statistically significant difference in Visual Analogue Scale (VAS) scores and bleeding scores between the two groups of mixed hemorrhoid surgery patients (all P>0.05); After 1 day of surgery, the VAS score and bleeding score of both groups of patients were significantly reduced (all P<0.05), and the observation group showed a more significant decrease (all P<0.05). The postoperative recovery rate of anal contraction in the observation group was higher than that in the control group ( P<0.05), and the rectal traction reflectance was lower than that in the control group ( P<0.05). The total incidence of adverse reactions in the observation group was significantly lower than that in the control group (χ 2=4.667, P<0.05). Conclusions:The combination of low-dose ropivacaine and sufentanil has a definite anesthetic effect on patients undergoing mixed hemorrhoid surgery. It can improve the onset time of anesthesia and postoperative rectal traction reflectivity, alleviate patient pain, and has high safety.
ABSTRACT
Objective:To evaluate the pharmacodynamics of remimazolam tosilate inducing loss of consciousness (LOC) when combined with sufentanil in children.Methods:American Society of Anesthesiologists Physical Status classificationⅠ or Ⅱ pediatric patients of either sex, aged 3-6 yr, undergoing electronic bronchoscopy, were included in this study. ECG monitoring was carried out in all children after admission, sufentanil 0.1 μg/kg was intravenously injected slowly, and 3 min later remidazolam tosilate was intravenously injected. The dose of remimazolam tosilate was determined by the modified Dixon′s up-and-down sequential experiment, and the initial dose of remimazolam tosilate was 0.30 mg/kg. The dose of remimazolam tosilate in the next child was determined according to the the loss of consciousness, and the successive dose gradient was 0.05 mg/kg. Loss of eyelash reflex and Modified Observer′s Assessment of Alertness/Sedation Scale score reaching 0 and the occurrence of 8 crossover points where consciousness transitioned from non-disappearance to disappearance after 1 min of remimazolam tosilate injection were considered to be signs of LOC. The median effective dose (ED 50), 95% effective dose (ED 95), and their 95% confidence interval ( CI) of remimazolam tosilate inducing LOC were calculated using probit method. Results:When combined with sufentanil, the ED 50 and 95% CI of remimazolam tosilate inducing loss of consciousness were 0.461 (0.429-0.493) mg/kg, and the ED 95 and 95% CI were 0.515 (0.487-0.689) mg/kg. Conclusions:When combined with sufentanil, the ED 50 of remimazolam tosilate inducing LOC is 0.461 mg/kg and the ED 95 is 0.515 mg/kg in children.
ABSTRACT
@#Objective To investigate the effect of propofol or different doses of remimazolam on effective dose(ED50)of sufentanil in elderly patients with tracheal intubation response by sequential method.Methods Elderly patients,American Society of Anesthesiologists(ASA)Ⅰ and Ⅱ,aged 65-80 years,undergoing elective surgery under general anesthesia with endotracheal intubation from October to December 2022 were selected and randomly divided into 4 groups:Group P(propofol 2mg/kg)and group R1,R2 and R3(remimazolam 0.2,0.3 and 0.4mg/kg)were administered intravenously.During anesthesia induction,sufentanil was given with the dose set by Dixon sequential method,followed by intravenous injection of propofol or corresponding dose of remimazolam and cisatracurium 0.15mg/kg.Tracheal intubation was performed when train of four(TOF)count was 0.If the tracheal intubation response is positive,the sufentanil dose of the next patient is increased by 1 concentration gradient,otherwise,the sufentanil dose is decreased by 1 concentration gradient,and the ratio between adjacent concentrations is 1∶1.1,until 7 turning points appear and the study is terminated.Probit regression analysis was used to calculate the median ED50 and 95%effective dose(ED95)of sufentanil for suppressing tracheal intubation response in elderly patients,and the corresponding 95%CI.The incidence of hypotension,bradycardia,injection pain and other adverse reactions were recorded.Results A total of 113 elderly patients were included in this study,including 24,28,30 and 31 patients in P,R1,R2 and R3 groups,respectively.The ED50 and ED95 and corresponding 95%CI of sufentanil for suppressing tracheal intubation response in elderly patients with propofol 2 mg/kg or remimazolam 0.2,0.3,0.4mg/kg were:The ED50 and ED95 of group P were 0.236μg/kg(95%CI:0.218-0.256)and 0.266μg/kg(95%CI:0.250-0.398),respectively.The ED50 and ED95 of group R1 were 0.284μg/kg(95%CI:0.265-0.309)and 0.329μg/kg(95%CI:0.306-0.478),respectively.The ED50 and ED95 of R2 group were 0.239μg/kg(95%CI:0.221-0.260)and 0.282μg/kg(95%CI:0.261-0.415),respectively.The ED50 and ED95 of R3 group were 0.198μg/kg(95%CI:0.182-0.211)and 0.231μg/kg(95%CI:0.216-0.303),respectively.The incidence of hypotension,bradycardia and injection pain in R1,R2 and R3 groups were lower than those in P group(P<0.05).The ED50 of sufentanil in group R2 was similar to that in group P,but the incidence of hypotension and injection pain in group R2 was lower than that in group P.Conclusion With the increase of the dose of remimazolam,the ED50 of sufentanil to inhibit tracheal intubation reaction in elderly patients gradually decreased,and in the case of similar ED50,the incidence of hypotension,bradycardia and injection pain induced by remimazolam was lower than that induced by propofol,so remimazolam induction was more advantageous in general anesthesia for tracheal intubation in elderly patients.
ABSTRACT
Objective To investigate different doses of the analgesic effects of dezocine comparing with sufentanil after laryngectomy.Methods A total of 129 patients who underwent elective partial laryngectomy from Feb 2022 to Jan 2023 were randomly assigned to dezocine 0.5 mg/kg group(group D1),dezocine 0.6 mg/kg group(group D2)and sufentanil 2 μg/kg group(group S).Twenty-four hours amount of drugs,the visual analogue scale(visual analogue scale,VAS)and 48 h total pressing times of PCA(patient-controlled intravenous analgesia,PCIA)were compared among the three groups at 6,12,24 and 48 h after operation,and the postoperative adverse reactions(nausea,vomiting,dizziness,urinary retention and respiratory depression)were recorded.Results There was no significant difference in 24 h amount of drugs among the three groups.The VAS score of group D1 was higher than that of group S at 6 h postoperatively(P<0.05),but did not differ significantly among the three groups at 12,24 and 48 h.There was no significant differences in the number of compressions and postoperative adverse reactions among the three groups.Conclusion Compared with sufentanil,0.6 mg/kg dezocine can provide the same degree of analgesic effect.However,no advantage was found to reduce adverse reactions.
ABSTRACT
Abstract Background: Brachial plexus block (BPB) has been accepted as a reliable alternative for general anesthesia in upper limb surgeries. Adding adjuvant drugs like dexmedetomidine and sufentanil has been shown to have clinical and pharmacologic advantages. In this randomized parallel clinical trial, we aim to compare the effects of these two adjuvants for bupivacaine in BPB. Methods: In this double-blinded study, by using computer-assisted block randomization, 40 patients ranged from 20 to 65 years old and scheduled for elective upper limb surgeries were assigned to two equal study groups (n = 20), receiving 1 mL of 5 μg.mL-1 sufentanil (group S) or 1 mL of 100 μg.mL-1 dexmedetomidine (group D) in adjunction to 30 mL of 0.5% bupivacaine for supraclavicular BPB under the guidance of ultrasonography. Characteristics of local anesthesia and postoperative analgesia were evaluated (n = 40). Results: The duration of blocks significantly improved in group S (sensory: estimated median difference (EMD) [95%CI] = 100.0 [70.0~130.0], p < 0.001; motor: EMD [95%CI] = 120.0 [100.0~130.0], p < 0.001). Group S also had significantly longer postoperative analgesia and lower opioid consumption within 24 hours after the surgery (EMD [95%CI] = 4.0 [3.0~7.0], p < 0.001; EMD [95%CI] = -5.0 [-5.0~-5.0], p < 0.001; respectively). None of the patients showed adverse effects concerning vital signs, nausea, or vomiting. Conclusion: Our study showed that during ultrasound-guided supraclavicular BPB, sufentanil is a fairly better choice than dexmedetomidine as an adjuvant for bupivacaine and can provide preferable sensory and motor blocks. No significant side effects were seen in either of the study groups.

ABSTRACT
Abstract Introduction Spinal infusions of either fentanyl or sufentanil have been reported in international reports, articles, and scientific events worldwide. This study aimed to determine whether intrathecal fentanyl or sufentanil offers safety in mortality and perioperative adverse events. Methods MEDLINE (via PubMed), EMBASE, CENTRAL (Cochrane library databases), gray literature, hand-searching, and clinicaltrials.gov were systematically searched. Randomized controlled trials with no language, data, or status restrictions were included, comparing the effectiveness and safety of adding spinal lipophilic opioid to local anesthetics (LAs). Data were pooled using the random-effects models or fixed-effect models based on heterogeneity. Results The initial search retrieved 4469 records; 3241 records were eligible, and 3152 articles were excluded after reading titles and abstracts, with a high agreement rate (98.6%). After reading the full texts, 76 articles remained. Spinal fentanyl and sufentanil significantly reduced postoperative pain and opioid consumption, increased analgesia and pruritus. Fentanyl, but not sufentanil, significantly reduced both postoperative nausea and vomiting, and postoperative shivering; compared to LAs alone. The analyzed studies did not report any case of in-hospital mortality related to spinal lipophilic opioids. The rate of respiratory depression was 0.7% and 0.8% when spinal fentanyl or sufentanil was added and when it was not, respectively. Episodes of respiratory depression were rare, uneventful, occurred intraoperatively, and were easily manageable. Conclusion There is moderate to high quality certainty that there is evidence regarding the safety and effectiveness of adding lipophilic opioids to LAs in spinal anesthesia.

Objective:To determine the 50% effective concentration (EC 50) of ropivacaine plus sufentanil for labor analgesia using the dural puncture epidural technique. Methods:Using the method of prospective study, sixty parturients requiring labor analgesia in Dalian Women and Children′s Medical Group from May 2021 to May 2022 were divided into six groups using a random number table and administered 0.3 mg/L sufentanil and ropivacaine at different concentrations: 0.05% (group D1), 0.06% (group D2), 0.07% (group D3), 0.08% (group D4), 0.09% (group D5), and 0.1% (group D6). A probit model was constructed to compute the EC 50 values and 95% confidence intervals (95% CI) of ropivacaine plus sufentanil in dural puncture epidural analgesia (DPEA) for labor. The pain intensity of uterine contractions before labor analgesia and 30 min after administration was recorded and assessed on a numeric rating scale (NRS), and decreases in blood pressures and heart rates, vomiting and nausea, postpartum headaches, and fetal bradycardia were documented. Results:When using ropivacaine plus sufentanil for labor analgesia via DPE, the EC 50 was 0.061%, and the 95% CI ranged from 0.051 to 0.067; the 90% effective concentration (EC 90) was 0.081%, and the 95% CI was between 0.074 and 0.098. Among the six groups, there was one case of fetal bradycardia in group D3 and one case of decreased heart rates in group D4. No decreased blood pressure, vomiting and nausea, or postpartum headaches were reported. Conclusions:In DPEA for labor, ropivacaine plus sufentanil has an EC 50 of 0.061%, with the 95% CI falling between 0.051 and 0.067, similar to the EC 50 value in epidural analgesia.
ABSTRACT
Objective:To investigate the effect of phloroglucinol combined with sufentanil on catheter-related bladder discomfort (CRBD) during anesthesia recovery in patients undergoing lobectomy for lung cancer under general anesthesia.Methods:A total of 95 lung cancer patients from the Cangzhou Central Hospital from May 2020 to June 2022 were selected as the study subjects and randomly divided into a control group (47 cases) and an observation group (48 cases) using a random number table method. The control group received intravenous injection of sufentanil approximately 15 minutes before the end of the surgery, while the observation group received intravenous injection of phloroglucinol combined with sufentanil. The recovery progress, lung function, relevant serum indicators, and occurrence of CRBD within 4 hours after surgery were compared between the two groups.Results:The observation group had shorter eye opening, free breathing, and extubation times than the control group (all P<0.05). Compared with before surgery, there were significant fluctuations in forced vital capacity (FVC), oxygenation index (OI), and partial oxygen pressure (PaO 2) during anesthesia resuscitation and 1 day after surgery in both groups (all P<0.05); The fluctuation amplitude of FVC, OI, and PaO 2 during anesthesia resuscitation and 1 day after surgery in the observation group was significantly smaller than that in the control group (all P<0.05). Compared with before surgery, hypoxia inducible factor-1α (HIF-1α) increased and brain-derived neurotrophic factor (BDNF) decreased in both groups on the first day after surgery (all P<0.05); The HIF-1α of the observation group was significantly lower than that of the control group on the first day after surgery, and the BDNF was significantly higher than that of the control group (all P<0.05). The comparison of the incidence of CRBD between the two groups at 4 hours after surgery showed that the observation group [12.50%(6/48)] was lower than the control group [31.91%(15/47)] (χ 2=4.286, P<0.05). Conclusions:The combination of phloroglucinol and sufentanil in general anesthesia patients undergoing lobectomy for lung cancer can reduce the occurrence of CRBD during anesthesia recovery, reduce the impact on lung function and serum HIF-1α and BDNF levels, and facilitate patient recovery.
ABSTRACT
Objective:To compare the efficacy of dexmedetomidine combined with sufentanil versus oxycodone for percutaneous transforaminal endoscopic surgery. Methods:Eighty patients with lumbar disc herniation undergoing percutaneous transforaminal endoscopic discectomy, aged 18-65 yr, were selected and divided into 2 groups ( n=40 each) according to the random number table method: dexmedetomidine combined with sufentanil group and dexmedetomidine combined with oxycodone group. Dexmedetomidine was given as a loading dose of dexmedetomidine 0.8 μg/kg (10-15 min) before surgery, followed by an intravenous infusion of 0.4-0.6 μg/kg until 10 min before the end of surgery. At 5 min before surgery, sufentanil was intravenously injected as a bolus of 0.1 μg/kg, followed by an intravenous infusion of 0.1 μg/kg until 10 min before the end of surgery in dexmedetomidine combined with sufentanil group, and oxycodone was intravenously injected as a bolus of 0.05 μg/kg, followed by an intravenous infusion of 0.05 mg/kg until 10 min before the end of surgery in dexmedetomidine combined with oxycodone group. The Ramsay sedation score, mean arterial pressure and heart rate were recorded before administration, before skin incision, at 10 min after the start of surgery, at polishing facet joints and at the end of surgery. Bispectral index value was also recorded before skin incision, at 10 min after the start of surgery, at polishing facet joints and at the end of surgery. The emergence time was recorded, and the emergence quality was evaluated using Steward score. The visual analog scale score was recorded before surgery and at 1, 6 and 24 h after surgery. Peripheral venous blood samples were taken before administration and at 1 h after surgery for determination of concentrations of serum angiotensin Ⅱ and endothelin by radioimmunoassay. The perioperative adverse reactions were recorded. Results:Compared with dexmedetomidine combined with sufentanil group, the Ramsay sedation score before skin incision, at 10 min after the start of surgery, at polishing facet joints and at the end of surgery was significantly increased, and the mean arterial pressure, heart rate and bispectral index value were decreased, and the visual analog scale score at each time point after surgery and serum angiotensin Ⅱ and endothelin concentrations at 1 h after surgery were decreased, the incidence of adverse reactions was decreased( P<0.05), and no significant change was found in Steward score and emergence time in dexmedetomidine combined with oxycodone group( P>0.05). Conclusions:Compared with sufentanil, dexmedetomidine combined with oxycodone has a better analgesia efficacy with fewer adverse reactions in the patients undergoing percutaneous transforaminal endoscopic surgery.
ABSTRACT
Objective:To investigate the effects of dezocine combined with sufentanil on continuous epidural analgesia after cesarean section.Methods:Eighty-six pregnant women who were scheduled for cesarean section in Guoyang Hospital of Traditional Chinese Medicine from February to December 2021 were included in this randomized controlled study. These women were divided into an observation group and a control group ( n = 43/group). The women in the observation group underwent epidural analgesia with dizocine, sufentanil, and ropivacaine, while those in the control group underwent epidural analgesia with dizocine and ropivacaine. The visual analogue score, Ramsay sedation score, Bruggrmann comfort scale score, and the incidence of adverse reactions were compared between the two groups. Results:At 4, 8, 12, 24 hours after surgery, the visual analogue score (VAS) in the observation group was significantly lower than that in the control group ( t = 2.34, 5.89, 15.36, 16.23, all P < 0.05). At 4, 8, 12, and 24 hours after surgery, Ramsay sedation score in the observation group was significantly higher than that in the control group ( t = -6.31, -7.64, -7.49, -7.41, all P < 0.001). At 4, 8, 12, and 24 hours after surgery, Bruggrmann comfort scale score in the observation group was significantly higher than that in the control group ( t = -7.60, -10.40, -14.53, -13.80, all P < 0.001). There was a significant difference in the number of effective analgesic pump compressions between the observation and control groups [(3.00 ± 1.41) times vs. (7.23 ± 1.31) times, t = 14.42, P < 0.001]. No adverse reactions were observed in the observation group within 24 hours after surgery. Conclusion:Dezocine combined with sufentanil for epidural analgesia can effectively improve the analgesic effects after cesarean section and is highly safe.
ABSTRACT
Objective:To investigate the effect of ropivacaine hydrochloride combined with sufentanil for intraspinal patient-controlled analgesia (PCA) in labor analgesia, and its influence on stress response and pregnancy outcome.Methods:The general data of 97 parturients who underwent intraspinal PCA delivery analgesia in Chengdu Seventh People′s Hospital from April 2019 to March 2021 were retrospectively analyzed. They were divided into the observation group (51 cases) and the control group (46 cases) according to different analgesia methods. The observation group parturients were given ropivacaine hydrochloride combined with sufentanil intraspinal PCA, and the control group parturients were given ropivacaine hydrochloride intraspinal PCA. The numerical scoring system (NRS) was used to evaluate the pain degree of the parturient before, 15 minutes after, 30 minutes after, 45 minutes after analgesia and when the uterine orifice was fully opened. The onset time of analgesia, the time of perfection of analgesia, the amount of ropivacaine hydrochloride, sufentanil and the total amount of analgesic drugs were counted. The levels of serum cortisol (COR), adrenocorticotropic hormone (ACTH) and Norepinephrine (NA) were detected by enzyme-linked immunosorbent assay (ELISA). The time of the first stage of labor, the active stage, the second stage of labor, and the third stage of labor, the amount of vaginal bleeding (during labor and within 2 hours after delivery), the proportion of oxytocin application, normal labor, forceps delivery, lateral perineum resection, and caesarean section, the occurrence of adverse reactions (itching, fever, nausea and vomiting, urinary retention, and fetal bradycardia), and the Apgar score of newborns (1 min and 5 min after birth) were counted.Results:There was no statistically significant difference in the onset time and improvement time of analgesia between the two groups of postpartum women, as well as the NRS scores before and after analgesia at 15, 30, and 45 minutes, as well as when the cervix was fully opened (all P>0.05). The dosage of Ropivacaine hydrochloride and the total amount of analgesics in the observation group were significantly less than those in the control group (all P<0.05). After analgesia, the serum levels of COR, ACTH, and NA in both groups decreased significantly compared to before analgesia (all P<0.05); After analgesia, there was no statistically significant difference in serum COR, ACTH, and NA levels between the two groups (all P>0.05). The second stage of labor in the observation group was shorter than that in the control group, the vaginal bleeding volume and the proportion of caesarean section were lower than those in the control group, the proportion of normal delivery and the Apgar score 1 min after birth of the fetus were higher than those in the control group, and the difference was statistically significant (all P<0.05). There was no statistically significant difference in the analgesic effect and total incidence of adverse reactions between the two groups of postpartum women (all P>0.05). Conclusions:Ropivacaine hydrochloride combined with sufentanil intraspinal PCA can effectively alleviate labor pain, reduce the amount of analgesics, and improve maternal and fetal pregnancy outcomes.
ABSTRACT
Objective To compare the sedative efficacy and safety of dexmedetomidine and sufen-tanil combined with propofol in elderly patients undergoing endoscopic retrograde cholangiopancreatography(ERCP).Methods Sixty elderly patients from July to October 2022,aged 65-90 years,BMI 15-33 kg/m2,ASA physical status Ⅰ-Ⅲ,had normal cardiac function or NHYA grade Ⅰ or Ⅱ,underwent ERCP were enrolled.Patients were divided into two groups by random number table method:the dexmedeto-midine group(group D)and the sufentanil group(group S),30 patients in each group.Group D received an intravenous infusion of dexmedetomidine 0.5 μg/kg for 10 minutes followed by intravenous propofol 1 mg/kg for sedation induction.Group S received intravenous sufentanil 0.12 μg/kg followed by intravenous propofol 1 mg/kg for sedation induction.The operation time,total dosage of propofol,incidence of body movement were recorded.The lowest SpO2,use of airway interventions,incidence of hypoxemia were recor-ded.Adverse cardiovascular events(tachycardia,bradycardia,hypertension,hypotension,and arrhythmia)were recorded.Awakening time,VAS pain scores at rest 15 minutes after entering PACU,incidence of mod-erate to severe postoperative pain,and postoperative nausea and vomiting in PACU were recorded.Results Adequate deep sedation was successfully achieved in the two groups(Ramsay scale≥5 scores).Compared with group S,the lowest SpO2 and bradycardia were significantly increased(P<0.05),the use of airway interventions,hypoxemia,tachycardia,and hypotension were significantly decreased in group D(P<0.05).There were no significant differences in operation time,total dosage of propofol,incidence of body movement,hypertension,VAS pain scores at rest 15 minutes after entering PACU,moderate to severe post-operative pain,and postoperative nausea and vomiting in PACU between the two groups.Conclusion Dexmedetomidine or sufentanil combined with propofol can provide adequate deep sedation for ERCP proce-dure.Dexmedetomidine combined with propofol can keep intraoperative cardiovascular function more stable,and reduce the occurrence of intraoperative hypoxemia and cardiovascular adverse events.
ABSTRACT
Objective:To evaluate the optimization efficacy of ropivacaine mixed with nalbuphine for epidural labor analgesia through comparison with ropivacaine mixed with sufentanil in primiparas.Methods:Four hundred and forty primiparas with a singleton fetus in vertex presentation without abnormal fetus, aged 19-36 yr, at 37-42 weeks of gestation, who were suitable and volunteered to receive epidural labor analgesia, were selected and randomly divided into observation group (NR group, n=220) and conventional group (C group, n=220).Epidural labor analgesia solution contained nalbuphine 40 mg and ropivacaine 120 mg in 150 ml of normal saline in group NR.Epidural labor analgesia solution contained sufentanil 50 μg and ropivacaine 120 mg in 150 ml of normal saline in group C. The analgesia pump was set up to deliver a 5 ml bolus dose with a 20-min lockout interval, programmed intermittent bolus 10-15 ml/h and background infusion at 2 ml/h after an initial dose of 15 ml to maintain VAS score <3.The length of labor, adverse reactions during labor analgesia, neonatal Apgar score, parameters of umbilical artery blood gas analysis and neonatal behavioral neurological assessment score were recorded. Results:Compared with group C, the incidence of urinary retention, pruritus, nausea and vomiting and fever at birth was significantly decreased in group NR ( P<0.05).The duration of the first and second stages of labor, neonatal Apgar score, pH value of umbilical artery blood, lactate concentrations, and neonatal behavioral neurological assessment score were within the normal range in both groups, and there was no significant difference between the two groups ( P>0.05). Conclusions:Compared with conventional medication, nalbuphine mixed with ropivacaine has the same efficacy when used for epidural labor analgesia in primiparas, but it has a certain optimization efficacy in terms of safety.
ABSTRACT
Objective:To investigate the efficacy and safety of hydromorphone for postoperative analgesia in children with congenital heart disease, and provide a suitable reference dose for postoperative analgesia in children.Methods:Using a prospective study, 157 patients with congenital heart disease(ASA Ⅱ- Ⅳ) admitted to pediatric intensive care unit at Children′s Hospital of Chongqing Medical University from November 2019 to November 2021 were randomly divided into five groups.Low-dose hydromorphone group (H1 group, 30 cases): hydromorphone dose ≥2 and <3 μg/(kg·h), hydromorphone medium-dose group (H2 group, 30 cases): hydromorphone dose ≥3 and <4 μg/(kg·h), high-dose hydromorphone group (H3 group, 31 cases): hydromorphone dose ≥4 and ≤5 μg/(kg·h), sufentanil group (S group, 36 cases): the dose of sufentanil was 0.08 μg/(kg·h), morphine group (M group, 30 cases): the dose of morphine was 20 μg/(kg·h). The five groups of children received midazolam 2 μg/(kg·min) intravenously at the same time as sedative therapy.Pain score and sedation score were scored at 1 h, 4 h, 8 h, 12 h, and 24 h after operation.Heart rate, mean arterial pressure, blood glucose, lactate, and serum cortisol levels were also monitored and detected, and the occurrence of adverse reactions, the number of cases requiring additional analgesic and sedative drugs, as well as the duration of mechanical ventilation were compared.Results:(1) There were no significant differences regarding the age, body weight, cardiopulmonary bypass time, pediatric critical illness score and ASA score among five groups (all P>0.05). (2) There was no significant difference in the levels of respiration, heart rate, blood sugar, lactate and serum cortisol among five groups after operation.There was no significant difference in preoperative mean arterial pressure among the groups, but there was significant difference in the postoperative mean arterial pressure among the groups at 4 h and 8 h( P<0.05). (3) The analgesic satisfaction of H1 group, H2 group and H3 group at 1 h, 4 h, 12 h and 24 h after operation was significantly higher than that in M group ( P<0.05). There was no significant difference in analgesic satisfaction among H1 group, H2 group and H3 group at each time point.(4) The sedation satisfaction of H1 group, H2 group and H3 group at 4 h and 24 h after operation was significantly higher than that in M group ( P<0.05). There was no significant difference in sedation satisfaction among H1 group, H2 group and H3 group at each time point.(5) There was no significant difference in postoperative analgesia satisfaction and sedation satisfaction between H1 group, H2 group, H3 group and S group.(6) Children in H1 group[1(0, 2)], H2 group[1(0, 2)], H3 group[1(0, 2)] had fewer additional doses within 24 hours than that in M group[2(2, 3)]( P<0.05), and fewer children in H1 group, H2 group and H3 group had been given analgesic sedatives than that in M group ( P<0.05); The extubation time was shortest in H2 group and S group[H2 group(88.3±2.9) h, S group(85.9±3.0) h]. (7) There were no adverse reactions in H1 group, H2 group, H3 group and S group, and there were two cases of apnea in M group. Conclusion:The analgesic effect of hydromorphone in children with congenital heart disease after surgery is better than that of morphine, and the effect of hydromorphone is comparable to that of sufentanil.Hydromorphone 3-4 μg/(kg·h)+ midazolam 2 μg/(kg·min) can achieve satisfactory analgesic and sedative effects in children after congenital heart surgery, with few adverse reactions, safe and reliable, which is an excellent choice for postoperative analgesia and sedation in children.
ABSTRACT
Objective:To investigate the efficacy of subarachnoid anesthesia with low-dose ropivacaine combined with sufentanil in cesarean delivery.Methods:A total of 120 women who were subjected to cesarean delivery in Tongxiang Second People's Hospital from May 2017 to April 2018 were included in this study. They were randomly assigned to undergo subarachnoid anesthesia either with low-dose ropivacaine plus sufentanil (observation group, n = 60) or low-dose ropivacaine alone (control group, n = 60) in cesarean delivery. The anesthesia effects, heart rate, mean arterial pressure, sensory block, 1-minute Apgar score, and the incidence of adverse reactions were compared between the two groups. Results:Time to anesthesia onset and time to pain recovery in the observation group were (2.07 ± 1.24) minutes and (51.29 ± 6.24) minutes, respectively, which were significantly shorter than those in the control group [(4.58 ± 1.69) minutes, (56.70 ± 7.91) minutes, t = 9.28, 4.16, both P < 0.05]. There was no significant difference in the duration of anesthesia between the two groups ( t = 0.76, P > 0.05). The heart rate, mean arterial pressure, and 1-minute Apgar score were (77.64 ± 6.20) beats/minute, (92.23 ± 1.38) mmHg, and (9.68 ± 0.70) points respectively in the observation group, which were significantly lower than those in the control group [(83.40 ± 5.93) beats/minute, (96.54 ± 4.06) mmHg, (7.59 ± 0.64) points, t = 5.20, 7.79, 17.07, all P < 0.05]. Time to onset of sensory block was significantly shorter in the observation group than in the control group [(52.07 ± 8.68) seconds vs. (64.30 ± 9.62) seconds, t = 7.31, P < 0.05]. Duration of sensory and motor block in the observation group were (161.75 ± 28.63) minutes and (86.26 ± 20.03) minutes, respectively, which were significantly longer than those in the control group [(130.29 ± 31.84) minutes, (78.60 ± 16.95) minutes, t = 5.69, 2.26, both P < 0.05]. The incidence of adverse reactions was significantly lower in the observation group than in the control group (5.00% vs. 16.67%, χ2 = 4.23, P < 0.05). Conclusion:Subarachnoid anesthesia with low-dose ropivacaine combined with sufentanil has satisfactory anesthetic effects in cesarean delivery. The combined therapy can stabilize hemodynamics, has little impact on newborns, and is highly safe.
