Sedation and analgesia in gastrointestinal endoscopy: What’s new?

Various types of sedation and analgesia technique have been used during gastrointestinal endoscopy procedures.The best methods for analgesia and sedation during gastrointestinal endoscopy are still debated.Providing an adequate regimen of sedation/analgesia might be considered an art,influencing several aspects of endoscopic procedures: the quality of the examination,the patient’s cooperation and the patient’s and physician’s satisfaction with the sedation.The properties of a model sedative agent for endoscopy would include rapid onset and offset of action,analgesic and anxiolytic effects,ease of titration to desired level of sedation,rapid recovery and an excellent safety prof ile.Therefore there is an impulse for development of new approaches to endoscopic sedation.This article provides an update on the methods of sedation today available and future directions in endoscopic sedation.

Safety of applying midazolam-ketamine-propofol sedation combination under the supervision of endoscopy nurse with patient-controlled analgesia pump in colonoscopy

AIM To compare the results of midazolam-ketaminepropofol sedation performed by an endoscopy nurse and anaesthetist during colonoscopy in terms of patient satisfaction and safety.METHODS American Statistical Association(ASA) Ⅰ-Ⅱ 60 patients who underwent colonoscopy under sedation were randomly divided into two groups: sedation under the supervision of an anaesthetist(SSA) and sedation under the supervision of an endoscopy nurse(SSEN). Both groups were initially administered 1 mg midazolam, 50 mg ketamine and 30-50 mg propofol. Continuation of sedation was performed by the anaesthetist in the SSAgroup and the nurse with a patient-controlled analgesia(PCA) pump in the SSEN group. The total propofol consumption, procedure duration, recovery times, pain using the visual analogue scale(VAS) and satisfaction score of the patients, and side effects were recorded. In addition, the patients were asked whether they remembered the procedure and whether they would prefer the same method in the case of re-endoscopy.RESULTS Total propofol consumption in the SSEN group was significantly higher(P < 0.05) than that in the SSA group. When the groups were compared in terms of VAS score, recovery time, patient satisfaction, recall of the procedure, re-preference for the same method in case of re-endoscopy, and side effects, there were no significant differences(P > 0.05) between the two groups. No long-term required intervention side effects were observed in either group.CONCLUSION Colonoscopy sedation in ASA Ⅰ-Ⅱ patients can be safely performed by an endoscopy nurse using PCA pump with the incidence of side effects and patient satisfaction levels similar to sedation under anaesthetist supervision.

Availability and quality of procedural sedation and analgesia in emergency departments without emergency physicians: A national survey in the Netherlands

BACKGROUND: Emergency physicians have been successful in implementing procedural sedation and analgesia(PSA) to treat emergency department(ED) patients who need to undergo painful procedures.However, 25% of the EDs in the Netherlands are not staffed by emergency physicians.The aim of this study was to investigate PSA availability and quality in EDs without emergency physicians.METHODS: We performed an exploratory cross-sectional study amongst ED nurses and physicians in all 13 EDs without emergency physicians in the Netherlands.Data were gathered using a standardized questionnaire.RESULTS: The response rate was 34.3%(148/432).Of the respondents, 84/148(56.8%) provided adult PSA and 30/148(20.3%) provided paediatric PSA.Main reasons for not providing PSA were insufficient numbers of trained staff to support PSA in the ED and insufficient training and exposure.The providers agreed significantly stronger when reflecting their PSA competencies in adults compared to paediatric patients.CONCLUSION: The key to improve pain management in the ED-setting may lay in investing in continuous training of ED health care professionals and/or acquiring professionals who are both qualified in PSA and available in the ED.

Process Management of Analgesia and Sedation Can Reduce the Incidence of Delirium

Background: Critical patients in ICU have to experience pain, anxiety, and sleep deprivation which always cause delirium, which will prolong the hospital stay and come up with higher mortality. Analgesia based sedation can reduce the accumulation of sedative effects, and shorten ventilator time and ICU length of stay. Process management of analgesia and sedation can reduce the incidence of delirium. Objectives: To explore the clinical benefits of procedural analgesia and sedation for critical ill patients. Methods: This is a prospective, two-phase study that focuses on patients who required mechanical ventilation after surgery. Comparing patients’ pain and agitation scores, the species and dosage of sedative and analgesic, the incidence of delirium in the observation period and intervention period, data in two groups were collected and analyzed. Results: During the observational and interventional periods, we enrolled 213 patients before protocol implantation and 196 patients after protocol implantation. We found that there existed impropriate pain and sedation assessment in patients involved, and after training for procedural protocol, the average dosage of sedatives was decreased (p > 0.05). The percentage of reaching standard COPT score was 73.7% vs 84.1% (p > 0.05) and RASS score was 70.9% vs 79.6% (p > 0.05) in the observation period and intervention period, and the incidence of delirium was significantly reduced (31.9% vs 23.5%, p Conclusion: We concluded that protocol implantation of analgesia and sedation can reduce the incidence of delirium.

End-tidal capnometry during emergency department procedural sedation and analgesia： a randomized, controlled study

BACKGROUND:This prospective,randomized trial was undertaken to evaluate the utility of adding end-tidal capnometry(ETC)to pulse oximetry(PO)in patients undergoing procedural sedation and analgesia(PSA)in the emergency department(ED).METHODS:The patients were randomized to monitoring with or without ETC in addition to the current standard of care.Primary endpoints included respiratory adverse events,with secondary endpoints of level of sedation,hypotension,other PSA-related adverse events and patient satisfaction.RESULTS:Of 986 patients,501 were randomized to usual care and 485 to additional ETC monitoring.In this series,48%of the patients were female,with a mean age of 46 years.Orthopedic manipulations(71%),cardioversion(12%)and abscess incision and drainage(12%)were the most common procedures,and propofol and fentanyl were the sedative/analgesic combination used for most patients.There was no difference in patients experiencing de-saturation(Sa O2<90%)between the two groups;however,patients in the ETC group were more likely to require airway repositioning(12.9%vs.9.3%,P=0.003).Hypotension(SBP<100 mm Hg or<85 mm Hg if baseline<100 mm Hg)was observed in 16(3.3%)patients in the ETC group and 7(1.4%)in the control group(P=0.048).CONCLUSIONS:The addition of ETC does not appear to change any clinically significant outcomes.We found an increased incidence of the use of airway repositioning maneuvers and hypotension in cases where ETC was used.We do not believe that ETC should be recommended as a standard of care for the monitoring of patients undergoing PSA.

Study on Analgesia and Sedation of Butorphanol Tartrate Combined with Dexmedetomidine in Severe Cerebral Hemorrhage for Patients with Mechanical Ventilation

Objective: To analyze the effect and advantages in analgesia and sedation of butorphanol tartrate combined with dexmedetomidine in severe cerebral hemorrhage for patients with mechanical ventilation. Methods: 120 patients with severe cerebral hemorrhage requiring analgesia and sedation were randomly selected and divided into two groups: the control group (dexmedetomidine treatment group) and the test group (dexmedetomidine combined with butorphanol tartrate). Two groups of patients with different drugs were analyzed. Results: The average dose of dexmedetomidine (microgram) and the total adverse events (Times) in the test group were significantly lower than those in the control group within 48 hours (P < 0.05);The dose of Butorphanol in the test group was small, and the patients in the control group used other opioid analgesics to pump more significantly. Conclusion: Using butorphanol tartrate combined with dexmedetomidine can achieve the same sedative effect and enhance the analgesic effect as using dexmedetomidine alone with less dose of dexmedetomidine, and the clinical effect is significant. It also solves the problem that adverse reactions such as blood pressure change and bradycardia are easy to occur when using large dose of dexmedetomidine and the infusion speed is fast in clinical application, and significantly reduces the incidence of adverse reactions. It is worthy of clinical application.

Monitoring salivary amylase activity is useful for providing timely analgesia under sedation

AIM:To detect the criteria and cause of elevated salivary amylase activity(sAMY)in patients undergoing endoscopic submucosal dissection(ESD)under sedation.METHODS:A total of 41 patients with early gastric cancer removed via ESD under deep sedation(DS)were enrolled.The perioperative sAMY,which was shown as sympathetic excitements(SE),was measured.The time at which a patient exhibited a relatively increased rate of sAMY compared with the preoperative baseline level(IR,%)≥100%(twice the actual value)was assumed as the moment when the patient received SE.Among the 41 patients,we focused on 14 patients who exhibited an IR≥100% at any time that was associated with sAMY elevation during ESD(H-group)and examined whether any particular endoscopic procedures can cause SE by simultaneously monitoring the sAMY level.If a patient demonstrated an elevated sAMY level above twice the baseline level,the endoscopic procedure was immediately stopped.In the impossible case of discontinuance,analgesic medicines were administered.This study was performed prospectively.RESULTS:A total of 26 episodes of sAMY eruption were considered moments of SE in the H-group.The baseline level of sAMY significantly increased in association with an IR of>100% at 5 min,with a significant difference(IR immediately before elevation/IR at elevation of sAMY=8.72±173/958±1391%,P<0.001).However,effective intervention decreased the elevated sAMY level immediately within only 5 min,with a significant difference(IR at sAMY elevation/immediately after intervention=958±1391/476±1031,P<0.001).The bispectral indices,systolic blood pressure and pulse rates,which were measured at the same time,remained stable throughout the ESD.Forceful endoscopic insertion or over insufflation was performed during 22 of the 26 episodes.Release of the gastric wall tension and/or the administration of analgesic medication resulted in the immediate recovery of the elevated sAMY level,independent of body movement.CONCLUSION:By detecting twice the actual sAMY based on the preoperative level,the release of the gastric wall tension or the administration of analgesic agents should be considered.

Airway Characteristics and Safe Management of Spontaneously Breathing Patients: Risks of Sedation and Analgesia and Changes in Wakefulness

The goal of safe airway management is to maintain a patent airway. Lack of knowledge of the anatomical morphology and changes that may occur in the upper airway during sedation and unconsciousness may lead to critical incidents and hazardous complications. This review focuses on the risks of sedation and analgesia and changes in wakefulness on airway patency in spontaneously breathing patients. Furthermore, key elements of airway management are presented and discussed.

Sedation in gastrointestinal endoscopy: Current issues

Diagnostic and therapeutic endoscopy can successfully be performed by applying moderate(conscious) sedation.Moderate sedation,using midazolam and an opioid,is the standard method of sedation,although propofol is increasingly being used in many countries because the satisfaction of endoscopists with propofol sedation is greater compared with their satisfaction with conventional sedation.Moreover,the use of propofol is currently preferred for the endoscopic sedation of patients with advanced liver disease due to its short biologic half-life and,consequently,its low risk of inducing hepatic encephalopathy.In the future,propofol could become the preferred sedation agent,especially for routine colonoscopy.Midazolam is the benzodiazepine of choice because of its shorter duration of action and better pharmacokinetic profile compared with diazepam.Among opioids,pethidine and fentanyl are the most popular.A number of other substances have been tested in several clinical trials with promising results.Among them,newer opioids,such as remifentanil,enable a faster recovery.The controversy regarding the administration of sedation by an endoscopist or an experienced nurse,as well as the optimal staffing of en-doscopy units,continues to be a matter of discussion.Safe sedation in special clinical circumstances,such as in the cases of obese,pregnant,and elderly individuals,as well as patients with chronic lung,renal or liver disease,requires modification of the dose of the drugs used for sedation.In the great majority of patients,sedation under the supervision of a properly trained endoscopist remains the standard practice worldwide.In this review,an overview of the current knowledge concerning sedation during digestive endoscopy will be provided based on the data in the current literature.

Effects of DEX on sedation, neurological function and cerebral oxygen metabolism in elderly patients with prostate cancer undergoing LRP

Objective:To study the sedative effect of dexmedetomidine in elderly patients with prostate cancer undergoing three hole LRP,and its effect on nerve function and brain oxygen metabolism.Methods:From August 2016 to December 2019,78 patients with LRP under general anesthesia in our hospital were randomly selected and divided into control group and observation group according to the random number table method,39 cases in each group.During the operation,the observation group was given dextromethoridine,while the control group was given the same amount of normal saline.The changes of cognitive function index(MoCA score,POCD incidence rate),neurological function index(TGF-β1,NSE,IGF-1),brain oxygen metabolism index(PaO2,map,PaCO2,rSO2)before and after operation were compared between the two groups.The visual analogue score(VAS),the amount of analgesic drugs and the times of pressing the analgesic pump were compared between the two groups.The incidence of adverse reactions was compared between the two groups.Results:Before operation,there was no significant difference in cognitive function index,neurological function index and brain oxygen metabolism index between the two groups(P>0.05).On the first and third days after operation,MOCA score of the two groups was significantly lower,MOCA score of the observation group was significantly higher than that of the control group,POCD incidence of the observation group was significantly lower than that of the control group;on the third day after operation,TGF-β1 and IGF-1 of the two groups were significantly lower,TGF-β1 and IGF-1 of the observation group were significantly lower-The NSE in the observation group was significantly lower than that in the control group(P<0.05).In this study,1 hour after the establishment of pneumoperitoneum,PaCO2 and rSO2 in the two groups were significantly increased,6 hours and 12 hours after the operation,the VAS score of the observation group was lower than that of the control group,and the dosage of analgesic pump and the number of times of compression of the analgesic pump were significantly lower than that of the control group(P<0.05).There was no difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusion:DEX has a good sedative effect on the elderly prostate cancer patients undergoing LRP with three hole method.It has little effect on nerve function and brain oxygen metabolism,and has a good safety.

新型药物艾司氯胺酮的特性与效能

氯胺酮最早于20世纪90年代在欧洲国家上市,最初被用作麻醉剂和战争创伤中的麻醉药,后由于其滥用导致精神运动、心血管系统等不良反应的限制,逐渐淡出临床工作中。艾司氯胺酮作为氯胺酮的右旋异构体,与其外消旋混合物相比,保留了药代动力学的特征,静脉注射后1分钟内便可达到峰值浓度,之后艾司氯胺酮及其代谢产物都主要通过肾脏排泄,不同的是艾司氯胺酮拥有更快的清除倾向和更大的总清除率;另外其药效动力学发生了变化,其镇静镇痛效力更强、所需剂量更小,达到相同麻醉效果用量仅为氯胺酮的1/2,且血流动力学变化更加平稳,锥体外系反应及其他不良反应也更加轻微。2019年艾司氯胺酮因其抗抑郁成果取得重大突破获得美国食品药品监督管理局(FDA)批准上市,自此作为一种新型药物重新进入临床麻醉工作视野中。目前艾司氯胺酮可用作麻醉诱导与维持、术后止痛、神经阻滞佐剂和抗抑郁等多种用途,复合用药时可减少丙泊酚和阿片类药物的使用量,更快创造插管条件,逆转阿片类药物的呼吸抑制,也可抑制瑞芬太尼诱发的痛觉过敏,同时具有镇静镇痛、产生意识消失和遗忘、抗炎抗应激、改善情绪等多重效能。本研究就艾司氯胺酮的药理学特性、临床应用等方面作如下综述,以供临床参考。

右美托咪定的中枢神经作用机制研究进展

右美托咪定是一种α_(2)肾上腺素受体激动剂,具有镇静、镇痛、抗焦虑、抗交感神经的作用,目前已经成为临床麻醉和重症监护室广泛应用的药物。相比于麻醉科其他药物,右美托咪定没有明显的呼吸抑制作用且没有明显的血流动力学改变,且与其他麻醉药配伍可明显减少镇静镇痛药物的用量。在临床应用中发现,右美托咪定可以介导可唤醒的镇静效应。传统认为右美托咪定通过α_(2)肾上腺素受体发挥作用,可以发挥降低血压、舒张血管和降低心率的作用,但对于其如何影响脑内神经环路尚不清楚。近年来关于右美托咪定作用机制的研究逐渐增多,证实下丘脑腹外侧视前区(ventrolateral preoptic nucleus,VLPO)、蓝斑核(locus coeruleus,LC)、中脑腹侧被盖区(ventral tegmental area,VTA)等核团参与其介导的镇静作用,背根神经节(dorsal root ganglion,DRG)、颈上神经节(superior cervical ganglion,SCG)参与其介导的镇痛作用,下丘脑视前区(preoptic area,PO)和下丘脑室旁核(paraventricular nucleus,PVN)参与其介导的体温和水电解质平衡的变化,为理解右美托咪定在中枢神经系统的作用机制提供了新的方向。
