Remazolam combined with transversus abdominis plane block in gastrointestinal tumor surgery:Have we achieved better anesthetic effects?

Laparoscopic surgery is the main treatment method for patients with gastrointestinal malignant tumors.Although laparoscopic surgery is minimally invasive,its tool stimulation and pneumoperitoneum pressure often cause strong stress reactions in patients.On the other hand,gastrointestinal surgery can cause stronger pain in patients,compared to other surgeries.Transversus abdominis plane block(TAPB)can effectively inhibit the transmission of nerve impulses caused by surgical stimulation,alleviate patient pain,and thus alleviate stress reactions.Remazolam is an acting,safe,and effective sedative,which has little effect on hemodynamics and is suitable for most patients.TAPB combined with remazolam can reduce the dosage of total anesthetic drugs,reduce adverse reactions,reduce stress reactions,and facilitate the rapid postoperative recovery of patients.

Effect of Subcostal Anterior Quadratus Lumborum Block vs.Oblique Subcostal Transversus Abdominis Plane Block after Laparoscopic Radical Gastrectomy

Objective:To evaluate the analgesic effect of ultrasound-guided subcostal anterior quadratus lumborum block(QLB)for laparoscopic radical gastrectomy surgery.Methods:Patients(aged 20-65 years,ASA Ⅰ-Ⅱ,and weighing 40-75 kg)scheduled for elective laparoscopic radical gastrectomy were enrolled in the current study.Sixty patients were randomly assigned to two groups by computer-generated randomization codes:an ultrasound-guided oblique subcostal transversus abdominis plane block(TAPB)group(group T,n=30)or an ultrasound-guided subcostal anterior QLB group(group Q,n=30).In both groups,bilateral ultrasound-guided oblique subcostal TAPB and subcostal anterior QLB were performed before general anesthesia with 0.25% ropivacaine 0.5 mL/kg.For postoperative management,all patients received patient-controlled intravenous analgesia(PCIA)with nalbuphine and sufentanil after surgery,maintaining visual analogue scale(VAS)scores<4 within 48 h.The intraoperative consumption of remifentanil,the requirement for sufentanil as a rescue analgesic,and the VAS scores at rest and coughing were recorded at 1,6,12,24 and 48 h after surgery.The recovery(extubation time after surgery,first ambulation time,first flatus time and length of postoperative hospital stay)and the adverse events(nausea and vomiting,skin pruritus,respiratory depression and nerve-block related complications)were observed and recorded.The primary outcome was the perioperative consumption of opioids.Results:Compared with group T,the intraoperative consumption of remifentanil,requirement for sufentanil and the frequency of PCIA were reduced in group Q.Meanwhile,VAS scores at all points of observation were significantly lower in group Q than in group T.Patients in group Q were also associated with shorter time to first out-of-bed activity and flatus,and shorter length of postoperative hospital stay than group T(P<0.05).There were no skin pruritus,respiratory depression or nerve-block related complications in both groups.Conclusion:Compared with ultrasound-guided oblique subcostal TAPB,ultrasound-guided subcostal anterior QLB provided greater opioid-sparing effect,lower visual analogue scores,and shorter postoperative hospital stay for laparoscopic radical gastrectomy.

Application of remimazolam transversus abdominis plane block in gastrointestinal tumor surgery

BACKGROUND Transversus abdominis plane block(TAPB)is a block of the abdominal afferent nerve fibers between the internal oblique muscle and the transverse abdominal muscle achieved with local anesthetics.It can effectively block the conduction of the anterior nerve of the abdominal wall and exert a good analgesic effect.However,the effect of combining the block with remimazolam on anesthesia in patients undergoing gastrointestinal tumor surgery is still unclear.AIM To examine the effects of combining TAPB with remimazolam on the stress response and postoperative recovery of gastrointestinal tumor surgery patients.METHODS A retrospective analysis was conducted on the clinical data of 102 individuals diagnosed with gastrointestinal malignancies who underwent laparoscopic surgery under general anesthesia between April 2020 and June 2023.The patients were categorized into a control group(n=51),receiving remimazolam for general anesthesia,and an observation group(n=51),receiving TAPB combined with remimazolam for general anesthesia.A comparison was made between both groups in terms of hemodynamic parameters,stress markers,pain levels,recovery quality,analgesic effects,and adverse reactions during the perioperative period.RESULTS The observation group had significantly higher heart rates at time points 1 min after induction and upon leaving the operating room than the control group(P<0.05).The mean arterial pressure at time point T1 in the observation group was significantly higher than that in the control group(P<0.05).Five minutes after extubation,the levels of the hormones adrenaline and noradrenaline in the observation group were considerably lower than those in the control group(P<0.05).At 12 h,24 h,and 48 h following surgery,the visual analog scale scores of the observation group were considerably lower than those of the control group(P<0.05).The observation group had shorter awakening and extubation times and lower Riker sedation-agitation scale scores than the control group(P<0.05).The observation group exhibited considerably fewer effective pump presses,lower fentanyl dosages,and lower incidences of rescue analgesia within 24 h following surgery than the control group(P<0.05).CONCLUSION The application effect of TAPB combined with remimazolam general anesthesia in anesthesia of patients undergoing gastrointestinal tumor surgery is good,which is helpful to promote faster recovery after operation.

Effect of Ultrasound-Guided Transversus Abdominis Plane Block Combined with Lornoxicam on Pain and Recovery Quality After Abdominal Surgery in Patients with Drug Addiction

Objective:This paper aims to analyze the analgesic effect of ultrasound-guided transversus abdominis plane block(TAPB)combined with non-steroidal anti-inflammatory analgesic drug lornoxicam on abdominal surgery in patients with a history of drug addiction.Methods:32 patients aged 18-60 who underwent lower abdominal surgery in the First People's Hospital of Liangshan Yi Autonomous Prefecture and Butuo County People's Hospital of Liangshan Yi Autonomous Prefecture from January 2022 to March 2023 were selected,the patients must have drug abuse history for more than 1 year,with a history of drug withdrawal and relapse.The patients were divided into observation group and control group by the envelope method,with 16 cases in the observation group and 16 cases in the control group.Two groups of patients underwent ultrasound-guided bilateral transversus abdominis plane block after the operation.The observation group was treated with dexmedetomidine hydrochloride 1μg/kg+0.25%ropivacaine hydrochloride 40ml,and the control group was treated with 40ml 0.9%sodium chloride injection,the two groups of patients returned to the ward after operation and given intravenous infusion of lornoxicam for relieving the pain.The visual analogue scale(VAS)score of postoperative pain,the times of rescue analgesia,the time of postoperative anal exhaust,the time of ambulation,nausea and vomiting,withdrawal symptoms,related adverse reactions,and hospitalization days were compared between the two groups.Results:The VAS score of postoperative pain in the observation group was significantly lower than that in the control group,P<0.05.Patients in the observation group used less postoperative rescue analgesics than those in the control group,P<0.05.For postoperative anal exhaust time,the difference between the two groups of patients was relatively small,and the time in the observation group was shorter,P>0.05.The time to get out of bed and the length of hospital stay were not significantly different between the control group and the observation group,P>0.05.The withdrawal symptoms of the patients in the observation group were better,P<0.05,nausea and vomiting,and other adverse reactions were lower in the control group,P<0.05.Conclusion:Ultrasound-guided transversus abdominis plane block combined with lornoxicam can be used to relieve pain in abdominal surgery for patients with drug addiction,which can effectively improve the therapeutic effect of patients and reduce the number of postoperative rescue analgesia.Thus,it has high clinical application value.

Objective To evaluate the effects of ultrasound-guided transversus abdominis plane(TAP) block on postoperative analgesia and early recovery in patients undergoing retroperitoneoscopic urologic surgeries.Methods This was a randomized,controlled,double-blinded trial.Eligible patients scheduled for retroperitoneoscopic urologic surgeries were randomly assigned to two groups.Group TAP received ultrasound-guided TAP block with 0.5% ropivacaine 20 ml at 30 minutes before surgery,and Group C received TAP sham block with normal saline.All patients received retroperitoneoscopic urologic surgeries under general anesthesia.The primary outcome was the severity of pain after surgery.Secondary outcomes included opioids consumption,analgesics,postoperative nausea and vomiting,time to Foley catheter removal and to passage of flatus,length of post-anesthesia care unit stay and hospital stay.Results Eighty patients completed the study,forty cases in each group.Compared to the Group C,the Group TAP had lower visual analogue scale pain scores within two postoperative days(all P<0.05).They also had less consumption of intraoperative fentanyl(2.0±0.5 vs. 3.8±0.7 μg/kg,P<0.05),reduced incidence of postoperative rescue analgesic usage(12.5% vs. 45.0%,P<0.05),and lower incidence of postoperative nausea and vomiting within postoperative 48 hours(12.5% vs. 25.0%,P<0.05) when compared to the Group C.In addition,Group TAP had a shortened post-anesthesia care unit stay(25±8 vs. 49±12 minutes,P<0.05),and a greater proportion of patients discharged within postoperative three days(57.5% vs. 35.0%,P<0.05).Conclusion Preoperative ultrasound-guided TAP block is an effective technique to improve postoperative analgesia and early recovery in patients undergoing retroperitoneoscopic urologic surgeries.

Analgesic effect of ultrasound-guided bilateral transversus abdominis plane block in laparoscopic gastric cancer

BACKGROUND Postoperative complications are important factors affecting the survival time and quality of life of patients undergoing radical gastrectomy.AIM To investigate and compare the anesthetic effects of intravenous general anesthesia combined with epidural anesthesia or ultrasound-guided bilateral transversus abdominal plane block(TAPB)in gastric cancer patients undergoing laparoscopic radical gastrectomy.METHODS The clinical data of 85 patients who underwent laparoscopic radical gastrectomy in our hospital from December 2020 to January 2023 were retrospectively collected and divided into a TAPB group(n=45)and epidural anesthesia group(n=40)according to the different anesthesia and analgesia programs used.The TAPB group received general anesthesia combined with TAPB,and the epidural anesthesia group received general anesthesia combined with epidural anesthesia.The pain status,cognitive status,intestinal barrier indicators,recovery quality,and incidence of complications were compared between the two groups.RESULTS Compared with the epidural anesthesia group,the TAPB group’s visual analog scale scores were significantly lower 6 h,12 h,24 h and 48 h after surgery(P<0.05).The incidence of postoperative cognitive dysfunction(POCD)in the TAPB group was significantly lower than that in the epidural anesthesia group,and the Mini-mental State Examination score 24 h after surgery was significantly higher in the TAPB group than the epidural anesthesia group(P<0.05).The levels of diamine oxidase and plasma D-lactate were significantly lower in the TAPB group than the epidural anesthesia group 24 h after surgery(P<0.05).The agitation score and the incidence of agitation during recovery were significantly lower in the TAPB group than epidural anesthesia group(P<0.05).The total incidence of postoperative complications in the TAPB group was 4.44%,significantly lower than the 20.00%in the epidural anesthesia group(P<0.05).CONCLUSION Compared with epidural anesthesia combined with general anesthesia,TAPB combined with general anesthesia had a good analgesic effect in laparoscopic radical gastrectomy and can further reduce the incidence of POCD and postoperative complications,improve the levels of intestinal barrier indicators,and improve postoperative recovery quality.

Ultrasound-guided peripheral nerve blocks for anterior cutaneous nerve entrapment syndrome after robot-assisted gastrectomy: A case report

BACKGROUND Anterior cutaneous nerve entrapment syndrome(ACNES)is a condition mani-festing with pain caused by strangulation of the anterior cutaneous branch of the lower intercostal nerves.This case report aims to provide new insight into the selection of peripheral nerve blocks for the ACNES treatment.CASE SUMMARY A 66-year-old woman manifested ACNES after a robot-assisted distal gastrec-tomy.An ultrasound-guided rectal sheath block was effective for pain triggered by the port scar.However,the sudden severe pain,which radiated laterally from the previous site,remained.A transversus abdominis plane block was performed for the remaining pain and effectively relieved it.CONCLUSION In this case,the trocar port was inserted between the rectus and transverse abdominis muscles.The intercostal nerves might have been entrapped on both sides of the rectus and transversus abdominis muscles.Hence,rectus sheath and transverse abdominis plane blocks were required to achieve complete pain relief.To the best of our knowledge,this is the first report on use of a combination of rectus sheath and transverse abdominis plane blocks for pain relief in ACNES.

Effect of Transverse Abdominis Plane Block on Chronic Post-Operative Pain—A Review

Chronic post-operative pain is a recognized adverse consequence of surgery;managing and preventing it are always a better choice. Proper choice of Anesthetic technique, use of combined anesthesia and pre-emptive analgesia may prevent and decrease the incidence of chronic post-operative pain. Transverse abdominis plane block (TAP Block) is a regional anesthesia technique following abdominal surgeries which involve injection of a large amount of local anesthetics in TAP, an anatomical space between the internal oblique and transverse abdominis muscle. The aim of this review is to show the effect and uses of TAP block as a combined anesthesia and multimodal analgesia in preventing chronic post-operative pain.

Focused Review: Efficacy of the Rector Spinae Plane Block

Since the original publication on the erector spinae plane (ESP) block in 2016, the technique of the ESP block has evolved significantly in the last few years. This review highlights recent developments in the technique for administering the ESP block and proposes directions for future research. Continuous efforts are being aimed at improving understanding regarding the administration of the ESP block. Current reports suggest that the ESP block provides effective analgesia in thoracic and abdominal sites in patients of all ages. However, no cohort studies or randomized controlled trials were performed in 2016 and 2017. The ESP block is an effective analgesic tool in a wide range of sites. However. We are uncertain how effective the ESP block is compared to other types of regional anesthesia. Therefore, more research on ESP blocks is required.

The Impact of Single Low Dose IV Magnesium Sulphate Adjuvant to Ultrasound Guided Transverses Abdominis Plain Block for Control of Postcesarean Pain

Objective: The aim of this study is to determine the role of preoperative low dose intravenous MgSO4 when given adjuvant to ultrasound guided transversus abdominis plane (TAP) block in augmenting postcesarean analgesic effects and reducing opioid requirements during the first 24 hours. Subjects and Methods: In this prospective, randomized double blind study, a total of sixty full term pregnant women were recruited for the study underwent caesarean section. Thirty patients were assigned to MgSO4 group (A) and another thirty to placebo group (B). Participants in group (A) received 50 mg/kg MgSO4 in 100 ml isotonic saline intravenous (IV) over 20 minutes prior to induction of general anesthesia by 30 minutes while participants in group (B) received 100 ml isotonic saline (placebo) by the same route and over the same duration as control. Results: Visual Analogue Scale (VAS) was analysed within 24 hours postoperatively. The mean pain score at 6 and 12 hours postoperatively was significantly lower in MgSO4 group compared to control group (40.4 ± 5.12 vs 53.6 ± 4.92;26.1 ± 3.01 vs 35.5 ± 3.98 respectively, p = 0.012, 0.005). Comparing both groups regarding the mean time interval of first rescue analgesia (morphine sulphate) requested by the patients, it was longer in MgSO4 group compared to control group. The total dose of rescue analgesia consumed during 24 hours was analysed and it was significantly higher in control group compared to MgSO4 group (10.1 ± 0.95 vs 6.2 ± 0.87, p = 0.001). Conclusion: We concluded that preoperative low doses (50 mg/Kg) of MgSO4 with general anesthesia combined with ultrasound guided TAP block offer longer postoperative pain free periods thus reducing total opioid consumption. In addition to the safety of the drug to the mother and fetus so we recommend IV MgSO4 as an adjuvant therapy with TAP block.
