Comparative Study of Levobupivacaine Versus Levobupivacaine With Dexmedetomidine as an Adjuvant in Transversus Abdominis Block for Postoperative Pain Relief in Abdominal Hysterectomy Patients: A Randomized, Double-Blind Study.

Background Adjuvants have been discovered to prolong the analgesic impact of local anesthetics (LA), while the transversus abdominis plane (TAP) block offers sufficient postoperative pain relief after various abdominal procedures. Nevertheless, the impact of the given LA will determine the duration of the TAP block. Thus, in this investigation, we aimed to estimate the analgesic impact of combining dexmedetomidine (DEX) with levobupivacaine in the TAP block for patients having an infraumbilical incision for an abdominal hysterectomy while under spinal anesthetic. Aim This study aimed to determine the analgesic effect of DEX (0.5 mcg/kg) to 20 ml of 0.25% levobupivacaine on each side in the TAPblock in patients undergoing total abdominal hysterectomy (TAH). Materials and methods Two groups of 30 patients each, with ASA grades 1 and 2, were randomly selected from patients. Group N, comprising 30 patients, had a bilateral TAP block using 2 mL of normal saline and 20 mL of 0.25% levobupivacaine. Group D (n = 30 patients) was given DEX at a dose of 0.5 mcg/kg (2 mL) in addition to 20 mL of 0.25% levobupivacaine given bilaterally. The TAP block was administered just after skin closure. Time of the initial analgesic dose administration; total fentanyl doses utilized as rescue analgesia; pain scores (numerical rating scale (NRS)) at 2, 4, 6, 8, 12, and 24 hours; and pre- and postoperative cortisol levels were also noted. For each group, 1 gram IV paracetamol was administered every eight hours. Drugs used for rescue analgesia (RA) were diclofenac 75 mg IV stat and fentanyl 1 mcg/kg. Results and discussion In addition to Group N having lower NRS scores at rest, Group D had a considerably longer time for initial rescue analgesia than Group N. There was also a significant decrease in the total fentanyl consumption and postoperative serum cortisol levels in Group D in contrast to Group N. Conclusion Potential adjuvant DEX prolongs postoperative analgesia in patients experiencing abdominal hysterectomy when used alongside LA in TAP.

Analgesic Strategies for Urologic Videolaparoscopic or Robotic Surgery in the Context of an Enhanced Recovery after Surgery Protocol: A Prospective Study Comparing Erector Spinae Plane Block versus Transversus Abdominis Plane Block.

Regional anesthesia in postoperative pain management has developed in recent years, especially with the advent of fascial plane blocks. This study aims to compare the ultrasound-guided bilateral erector spinae plane block (ESPB) versus the ultrasound-guided bilateral transversus abdominis plane block (TAPB) on postoperative analgesia after laparoscopic or robotic urologic surgery. This was a prospective observational study; 97 patients (ESPB-group) received bilateral ultrasound-guided ESPB with 20 mL of ropivacaine 0.375% plus 0.5 mcg/kg of dexmedetomidine in each side at the level of T7-T9 and 93 patients (TAPB-group) received bilateral ultrasound-guided TAPB with 20 mL ropivacaine 0.375% or 0.25%. The primary outcome was the postoperative numeric rating scale (NRS) pain score, which was significantly lower in the ESPB group on postoperative days 0, 1, 2, and 3 (p < 0.001) and, consequently, the number of patients requiring postoperative supplemental analgesic rescue therapies was significantly lower (p < 0.001). Concerning the secondary outcomes, consumption of ropivacaine was significantly lower in the group (p < 0.001) and the total amount of analgesic rescue doses was significantly lower in the ESPB-group than the TAPB-group in postoperative days from 2 to 4 (1 vs. 3, p > 0.001). Incidence of postoperative nausea and vomiting was higher in the TAPB group and no block-related complications were observed. Our data indicate that ESPB provides postoperative pain control at least as good as TAPB plus morphine, with less local anesthetic needed.

A randomized comparative study of transversus abdominis plane block (tap) with 0.25% bupivacaine and 0.375% ropivacaine in the duration of post-operative analgesia in upper abdominal laparoscopic surgeries

Transversus abdominis plane (TAP) block is a successful postoperative analgesia technique in laparoscopic surgeries. This study compared the analgesic efficacy of 0.25% bupivacaine and 0.375% Ropivacaine in TAP block as post-operative analgesia for upper abdomen laparoscopic surgeries.: This randomized, double-blinded comparative study was conducted at the Dr Jeyasekharan Medical Trust and Nursing Home for 18 months. Seventy-one consenting adult patients undergoing upper abdominal laparoscopic surgeries qualifying the inclusion criteria to undergo Bilateral Subcostal TAP Block were included. The patient was labelled group A or B according to a computer-generated randomization list. TAP block was administered using 30 ml (15 ml on each side) of 0.25% bupivacaine (A) or 0.375% ropivacaine (B). Similar premedication and induction were given to all patients. : Among 71 patients in group A, males were 5 (14.7%), and females were 29 (85.3%). In group B, males were 7 (18.9%), and female was 30 (81.1%). There is no significant difference in gender, age, and BMI between groups. The mean duration of analgesia with 0.375% ropivacaine (10.21±3.36 hrs.) was significantly higher than 0.25% bupivacaine (6.38±2.03 hrs.). In the first 24 hours postoperatively, the mean total tramadol consumption was 147.06±11.94 mg in group A and 117.57±31.11 mg in group B, which is statistically significant.: This study concludes that 0.375% 30ml ropivacaine given as a TAP block under ultrasound guidance significantly prolonged the post-operative analgesia duration compared to 0.25% 30ml bupivacaine.

Pre-peritoneal Plus Portal Infiltration Versus Bilateral Transversus Abdominis Plane Block in Laparoscopic Hernia Repair.

Background and objective The role of the pre-peritoneal infiltration of local anesthetic (PILA) in laparoscopic hernia repair has been equivocal. Ultrasound-guided transversus abdominis plane (TAP) block has been extensively studied. However, studies comparing these two methods are very scarce. Hence, this study was undertaken to compare the efficacy of pre-peritoneal plus portal infiltration with TAP block in this population. Materials and methods This double-blinded randomized comparative study was conducted on a total of 32 patients by allotting 16 patients in each group. Group A patients were given pre-peritoneal plus portal infiltration of 15 mL of 0.5% ropivacaine for each technique by the operating surgeon, while Group B patients were administered bilateral TAP block with 0.5% ropivacaine, 15 mL on each side under ultrasound guidance by the anesthesiologist. Results The demographic variables and duration of surgery were comparable between the two groups. Also, the postoperative requirement of fentanyl between the two groups was insignificant. However, the duration of anesthesia was significantly longer in Group B attributing to the extra time taken for the administration of the TAP blocks. Conclusion Both ultrasound-guided TAP block and the PILA plus portal infiltration are effective techniques for pain relief after laparoscopic hernia repair. Either of these two techniques can be chosen depending on the availability of resources, expertise, etc.

Comparison of Dexamethasone Versus Methylprednisolone With Bupivacaine in Transversus Abdominis Plane Block for Attenuation of Chronic Postoperative Abdominal Pain.

Background Opioids, which have well-known adverse effects such as drowsiness paralytic ileus and respiratory depression, were mostly utilised to treat postoperative pain in the past. The increased incidence of side effectshas led to a rise in interest in pain management techniques that spare opioids. Persistent abdominal pain following surgery has a major detrimental effect on patients' quality of life. While epidural analgesia is widely regarded as the gold standard to combat the pain that is present post abdominal surgeries, it is not devoid ofdrawbacks. The transversus abdominis plane (TAP) block has developed as a potentially effective treatment for severe abdominal pain. The TAP block acts on the neuro-fascial plane between the internal oblique and transversus abdominis muscles, which is innervated by spinal nerves from T6 to L1. Studies reveal that the addition of corticosteroids to bupivacaine in TAP blocks provides pain relief and improves the quality of life of the patient. Aims and objectives In this study, the effects ofbupivacaine and corticosteroids, particularly dexamethasone and methylprednisolone, on chronic abdominal pain following surgery are examined. Assessing the quality of pain relief is the primary objective. Methodology Thirty patients who had undergone abdominal surgery and had been having persistent abdominal pain for six to eight months thereafter and had attempted unsuccessfully to treat the pain with alternative pain relief methods participated in the study. They were divided into two groups at random. Dexamethasone and bupivacaine were given to patients in Group D while methylprednisolone and bupivacaine were given to patients in Group M for ultrasonography (USG)-guided bilateral TAP blocks. At various intervals up to 12 weeks after injection, the patient's pain levels were measured using the visual analogue score (VAS), and their quality of life was assessed using the quality-of-life score. Results Patients in Group M experienced significantly less pain than those in Group D at the fourth, sixth, and 12th weeks of treatment. Furthermore, in the fourth, sixth, and 12th weeks, patients in Group M reported a superior quality of life in comparison to those in Group D. Conclusion Patients with persistent postoperative abdominal pain receiving bupivacaine and methylprednisolone in an ultrasonography-guided TAP block experience more effective and long-lasting pain relief than those who receive bupivacaine and dexamethasone. The quality of life for patients may be enhanced by using corticosteroids to optimise postoperative pain management strategies and lessen the need for opioids, as this study highlights.

Comparative study between ultrasound-guided transversus abdominis plane block and spinal morphine for pain relief after an elective cesarean section

Background Severe acute pain occurs in more than 10% of patients within the first 36 h after a cesarean section and can significantly impact women’s satisfaction. The aim of this study was to compare the transversus abdominis plane (TAP) block for postoperative pain relief following cesarean section operations with the most famous analgesia (intrathecal morphine) used for a cesarean section regarding its efficacy and complications. Patients and methods This interventional double-blinded randomized controlled study was carried out on 60 cases, who underwent an elective cesarean delivery. They were randomized into two groups; patients were divided into two equal groups. Group M received intrathecal 150 μg morphine in a 0.5 ml volume, mixed with 10 mg of hyperbaric bupivacaine 0.5% in a 2 ml volume (total volume 2.5 ml). Group B received intrathecal 10 mg hyperbaric bupivacaine 0.5% 2 ml volume+0.5 saline (total volume 3 ml) and at the end of surgery the patient received bilateral TAP block with a 20 ml volume of 0.25% bupivacaine on each side. Results Postoperative heart rate, respiratory rate, oxygen saturation, mean arterial blood pressure, and intraoperative Bromage score were insignificantly different at all-time measurements between both groups. Visual analog score and postoperative Bromage score at 2, 3, and 4 h were higher in group B than group M (P&lt;0.001). Time of rescue analgesia was significantly prolonged in group M than group B (P&lt;0.001). Total paracetamol and morphine doses were significantly lower in group M than group B (P&lt;0.001). Conclusions TAP block is a good alternative technique to intrathecal morphine in reducing postcesarean section pain, with less postoperative nausea and vomiting and pruritus compared with intrathecal morphine (ITM).

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 &lt; 0.05. Patients in the observation group used less postoperative rescue analgesics than those in the control group, P &lt; 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 &gt; 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 &gt; 0.05. The withdrawal symptoms of the patients in the observation group were better, P &lt; 0.05, nausea and vomiting, and other adverse reactions were lower in the control group, P &lt; 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.

FTP7.7 Does bilateral combined Transversus Abdominis Plane (TAP) and rectus sheath block reduce postoperative pain after “hot laparoscopic cholecystectomy” compared to trocar site local anaesthetic infiltration?

Abstract Introduction Post-operative pain is the commonest reason for prolonged hospital stay and readmission following laparoscopic cholecystectomy. We aim to assess whether bilateral transversus abdominis plane (TAP) and rectus sheath block reduces post-operative pain compared to local anaesthetic (LA) wound infiltration following “hot” laparoscopic cholecystectomies. Methods Prospective study involving 15 patients who underwent laparoscopic cholecystectomy in dedicated “hot lists” between October and December 2022. Post-operative pain scores were recorded 4 hours, 3 days, and 5 days post-procedure. Pain scores of patients who received bilateral TAP and rectus sheath blocks were compared with those who received LA wound infiltration with 0.5% Levobupivacaine. Results 9 patients received TAP and rectus sheath blocks, and 6 patients received LA infiltration. The time from start of anaesthesia to start of surgery in the TAP block group was significantly higher than the LA group (P=0.039). There was no statistical difference in pain scores on the pain analogue scale (1-10) between groups at 4 hours (P=0.73), 3 days (P=0.27), or 5 days (P=0.33) post-surgery. There was no statistical difference between the 2 groups in length of hospital stay post-procedure (P=0.75), or in re-admission rates due to poorly controlled post-operative pain (P=0.58). Conclusion Bilateral TAP and rectus sheath blocks do not significantly reduce pain post “hot laparoscopic cholecystectomy” any more than LA wound infiltration. Given the extra time taken to perform TAP and rectus sheath blocks, a larger study population would be required to more reliably assess their benefits, given the importance of avoiding overrunning of the “hot list”.

Transversus abdominis plane block with ropivacaine provides effective analgesiain patients undergoing total abdominal hysterectomy

: Transversus abdominis plane (TAP) block provides a novel approach for analgesia in abdominal surgery by blocking the sensory nerve supply of the anterior abdominal wall. We evaluated the analgesic efficacy of TAP block with ropivacaine in patients undergoing total abdominal hysterectomy (TAH). 60 adult patients of ASA Grade 1 and 2 undergoing elective TAH were randomized into two groups in this double blind study. All patients received a standard general anaesthetic and before the surgical incision, a bilateral TAP block using the landmark technique was performed with 15 to 20 mlof 0.375% ropivacaine (maximum dose 3mg/kg) (Group R) or saline (Group C). Assessment of hemodynamic parameters and requirement of vecuronium and opioids was noted intraoperatively. Postoperative assessment of pain was performed at regular intervals using visual analog scale (VAS) and categorical pain score (CPS), and total analgesics administered over 48 hrs were noted.: Intraoperative hemodynamic parameters showed significantly lower mean values in the ropivacaine group till 50 minutes and from 80 to 120 minutes after the surgical incision. (p value&amp;#60;0.05). Duration of TAP block was significantly longer in the ropivacaine group (383 mins vs 221mins, p=0.000). Mean intraoperative requirement of fentanyl and vecuronium (p=0.000), and postoperative requirement of diclofenac at 24 hrs (p=0.004) and 48 hours (p=0.007) was significantly lower in Group R.VAS and CPS scores were significantly lower in the ropivacaine group till 2 hours postoperatively(p=0.000). : TAP block with ropivacaine provides effective intraoperative analgesia and decreases postoperative analgesic requirement till 48hours in patients undergoing total abdominal hysterectomy.

Efficacy of analgesia using ilioinguinal-iliohypogastric (IIIH) nerve block, transversus abdominis plane (TAP) block and diclofenac after caesarean delivery under spinal anaesthesia: A non-randomised clinical trial.

Our aim was to assess the efficacy of analgesia using ilioinguinal-iliohypogastric (IIIH) nerve block, transversus abdominis plane (TAP) block and diclofenac after caesarean delivery (CD) under spinal anaesthesia (SA).]. A total of 457 healthy parturients undergoing CD under SA were included in this prospective, observational study. Groups differed in the postoperative analgesic strategies received by the parturient at the end of surgery: group D (n = 148) received intramuscular diclofenac sodium, group I (n = 153) received bilateral IIIH block with bupivacaine plus clonidine and group T (n = 156) received bilateral TAP block with bupivacaine plus clonidine. Total duration of postoperative analgesia, numerical pain rating scale (NRS) scores, patient satisfaction score, rescue analgesics in the first 48 h postoperatively and adverse effects were observed. A value of P < 0.05 was taken as significant. Total duration of analgesia was longest (18.2 ± 1.3 h) in group T and shortest in group D (6.3 ± 0.8 h) compared to group I (13.1 ± 1.2 h) (P < 0.001). Total analgesic requirement in postoperative 48 h was lowest in group T (152.1 ± 34.9 mg), highest in group D (355.0 ± 25.6 mg) and intermediate in group I (221.0 ± 30.0 mg) (P < 0.001). Mean NRS scores were lower in group T compared to those in groups D and I. The patients in group T were extremely satisfied, in group I were satisfied and in group D were dissatisfied (P < 0.001). Bilateral TAP block with bupivacaine and clonidine after CD under SA increases the duration of postoperative analgesia.

Bilateral transversus abdominis plane (TAP) block reduces pain and the need for additional analgesics after elective cesarean section under opioid-free spinal anesthesia: findings from a randomized clinical trial

BackgroundCesarean section (CS) is the most frequently performed obstetric procedure globally, and postoperative pain remains a prominent concern. This study aimed to evaluate the effectiveness of the bilateral transversus abdominis plane (TAP) block in addressing this issue.MethodsWe performed a randomized trial in women with term pregnancies who underwent elective CS with spinal anesthesia. The women were randomized (1:1) to receive bilateral TAP or postoperative systemic analgesics (control group). The primary outcome was the effect on postoperative pain assessed using the numeric rating score (NRS) at 2, 6, 12, and 24 h in the postoperative period.ResultsAt 2 and 6 h after the surgical procedure, there was a significant reduction in both resting (rNRS p = 0.004) and movement-related pain (dNRS p = 0.0001, p = 0.001 respectively). However, at 12 h, a reduction of dNRS was demonstrated (p = 0.0001), while no benefit was observed at rest. The percentage of women with NRS ≤ 4 was higher after the block at 2 h for both resting and movement-related pain (rNRS p = 0.010; dNRS p = 0.0001); at 6 and 12 h, it was only significant for dNRS (p = 0.002). Rescue doses of analgesics were significantly higher in the control group at 2, 6, and 12 h (p = 0.01, p = 0.0383, p = 0.0003 respectively). No complications with the procedure were recorded.ConclusionBilateral TAP block has the potential to alleviate postoperative pain and reduce the need for additional analgesics after CS.Trial registrationThis study is registered with ClinicalTrials.gov, number (NCT02801968), registered 28 May 2016, https://clinicaltrials.gov/ct2/show/NCT02801968?term=NCT02801968&draw=2&rank=1

Randomized comparison between transversus abdominis and erector spinae blocks in cesarean section

Introduction: Transversus abdominis plane (TAP) block provides somatic analgesia postoperatively in cesarean sections, however erector spinae plane (ESP) block has shown to provide both somatic and visceral analgesia.&#x0D; Objective: To compare the efficacy of TAP and ESP blocks for pain control after cesarean section under spinal anesthesia.&#x0D; Methods: In a double-blind superiority trial, pregnant patients undergoing cesarean section were randomized into either bilateral TAP or ESP block groups. Primary outcome was total consumption of patient-controlled analgesia (PCA) tramadol in the first 24 hours. Secondary outcomes included time required for first rescue analgesia, post-surgery visual analog score (VAS) for pain, patient satisfaction, and adverse effects.&#x0D; Results: 50 pregnant patients were randomized into TAP and ESP blocks. There was no difference in the amount of PCA tramadol within the first 24 hours between both groups [100mg (63,125) in TAP group vs 75mg (38,100) ESP group]. Pain score at rest and on movement and patient satisfaction were comparable in both groups, with no difference in adverse effects. There was a slight difference in the median time for first rescue analgesia [210min (135,315) in TAP group and 270min (225,405) ESP group] (p=0.03).&#x0D; Conclusion: TAP and ESP blocks provide similar analgesia with comparable consumption of tramadol in the first 24 hours post-cesarean section and no difference in pain scores at rest/on movement.

The Role of Ultrasound-Guided Multipoint Fascial Plane Block in ElderlyPatients Undergoing Combined Thoracoscopic-Laparoscopic Esophagectomy: A Prospective Randomized Study.

We estimated the safety and efficacy of ultrasound-guided multipoint fascial plane block, including serratus anterior plane block (SAPB) and bilateral transversus abdominis plane block (TAPB) in elderly patients who underwent combined thoracoscopic-laparoscopic esophagectomy (TLE). The authors enrolled 80 patients in this prospective study after patient selection using the inclusion and exclusion criteria who were scheduled for elective TLE from May 2020 to May 2021. Patients were randomly assigned to the treated group (group N) or the control group (group C) (n = 40 per group) using the sealed-envelope method. Multipoint fascial plane blocks, including serratus anterior plane block (SAPB) and bilateral TAPB, were performed on patients undergoing TLE using a solution of 60mL 0.375% ropivacaine plus 2.5mg dexamethasone by 3 injections of 20mL each (group N) or no interventions (group C). Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) at T incision and 30min after T incision were significantly higher in group C than in group N, and also significantly higher than at baseline (P < 0.01). Blood glucose at 60min, 2h after T incision, was significantly higher in group C than in group N and significantly higher than at baseline (P < 0.01). Compared to group N, the dosages of propofol and remifentanil used during surgery in group C were more than those in group N (P < 0.01). The time to first rescue analgesic in group C was earlier than in group N. The total postoperative use of sufentanil, and the number of patients requiring rescue analgesics in group C, were more than in group N (P < 0.01). This study showed that applying the multipoint fascia pane block technique in TLE for elderly patients could significantly reduce postoperative pain, decrease the dosages of drugs used in general anesthesia, improve the quality of the awakening, and have no obvious adverse reactions.

Transversus abdominis plane block for anterior lumbar interbody fusion: a randomized controlled trial

BACKGROUND CONTEXTAnterior lumbar interbody fusion (ALIF) is a lumbar arthrodesis technique via an anterior approach that is less invasive than the posterior approaches. However, it is associated with specific pain in the abdominal wall. PURPOSEThe objective of this study was to determine whether performing a bilateral ultrasound-guided Transversus abdominis plane (TAP) block allows a reduction in morphine consumption in the first 24 hours after surgery. STUDY DESIGNThis study is a prospective single-center, randomized, double-blind study. PATIENT SAMPLEPatients undergoing ALIF surgery were included and randomized into two groups. Both groups received a TAP block performed at the end of surgery with either ropivacaine or placebo. OUTCOME MEASURESThe primary outcome measure was morphine consumption in the first 24 hours. The main secondary outcomes were immediate postoperative pain and opioid-related side effects. METHODSIntra- and postoperative anesthesia and analgesia protocols where standardized. A bilateral ultrasound-guided TAP block was performed with 75 mg (in 15 mL) of ropivacaine per side or isotonic saline serum depending on their assignment group. RESULTSForty-two patients were included in the study (21 per group). Morphine consumption at 24 hours (28 mg [18–35] in the ropivacaine group versus 25 mg [19–37] in the placebo group [p=.503]) were not significantly different between the two groups. CONCLUSIONTAP block with ropivacaine or placebo provided a similar postoperative analgesia when associated with a multimodal analgesia protocol for ALIF.

Efficacy of Magnesium Sulfate as an Adjuvant to Bupivacaine in Transversus Abdominis Plane Block for Abdominal Hysterectomy Surgeries.

Background Major abdominal surgeries are often accompanied by excruciating pain, which, if not adequately managed, can reduce patient comfort and satisfaction, delay mobilization, compromise respiratory and cardiac functioning, and increase healthcare costs. The transversus abdominis plane (TAP) block is an efficient and safe complement to multimodal postoperative analgesia for abdominal surgery. This study evaluates the efficacy of combining magnesium sulfate (MgSO4) with bupivacaine for TAP block in patientsposted for total abdominal hysterectomy (TAH). Methodology Seventy female patients between the ages of 35 and 60 who were scheduled to have a TAH under spinal anesthesia were divided randomly into two groups of 35 each: group Bupivacaine (B) and group Bupivacaine-Magnesium sulfate (BM). Group B received 18 milliliters (mL) of bupivacaine 0.25 percentage (%) 45 milligrams (mg) with 2 mL normal saline (NS) whereas group BM received 18 mL of bupivacaine 0.25% (45 mg) with 1.5 mL of 10% weight/volume (w/v) MgSO4 (150 mg) and 0.5 mL NS in the ultrasonography-guided (USG) bilateral TAP block performed after the end of surgery. Groups were compared for the postoperative visual analog scale (VAS) scores, the time required for first rescue analgesia, the number of analgesic rescues at various time intervals, patient satisfaction score, and any side effects. Results Postoperative VAS scores at 4, 6, 12 and 24th hour (hr) (p < 0.05) in group BM were lower compared to group B.Time required for rescue analgesia was significantlyprolonged in group BM (882.94 ± 70.22 minutes) compared to group B (459 ± 100.53 minutes) with minimal usage of rescue analgesia (p < 0.05)up to 12 hr.In group BM, the patient satisfaction score was higher (p = 0.001). Conclusion In addition to a considerable reduction in post operative VAS scores and overall use of rescue analgesia, the addition of magnesium to bupivacaine significantly prolongs the TAP block and increases the initial postoperative period of bearable pain.

Effects of different anesthesia methods on postoperative immune function in patients undergoing gastrointestinal tumor resection

To investigate the effects of different anesthetic methods on postoperative immune function in patients undergoing gastrointestinal tumor resection. Ninety patients undergoing laparoscopic gastrointestinal tumor resection were divided into 3 groups. Patients in the GA group were anesthetized by total intravenous anesthesia. The GE group was anesthetized by general anesthesia combined with epidural anesthesia. The GN group was anesthetized by general anesthesia combined with bilateral Transversus Abdominis Plane block (TAP) and rectus sheath nerve blocks. General anesthesia is total intravenous anesthesia in all three groups. Blood samples were taken to test the changes of peripheral lymphocyte subtype analysis, and levels of plasma cortisol, epinephrine, norepinephrine. Also, the dosage of anesthetic drugs, recovery time, and visual analog scale (VAS) scores were recorded. Postoperative immune indexes, including CD4 count, CD8 count, B, and NK cells, in the GE group were significantly higher than those in NA and GA groups (P < 0.01). Perioperative stress indices, including epinephrine levels, norepinephrine level and aldosterone level, in the GE group were significantly lower than in the GA group and GN group (P < 0.01). The intraoperative/total sufentanil dosage and remifentanil dosage in the GE group were significantly lower than those in the GA and GN groups (P < 0.01). The VAS scores in the GE group were significantly better than those in GA and GN groups (P < 0.01). General anesthesia combined with epidural anesthesia attenuates the increase in inflammatory mediators. Its possible mechanisms include reducing perioperative stress response and reducing perioperative opioid use.

Analgesic efficacy of ultrasound-guided bilateral transversus abdominis plane block in children: retrospective analysis of 97 cases.

Transversus abdominis plane (TAP) block is a method for postoperative pain management. Studies on children are gradually increasing. The aim of this retrospective study was to evaluate effectiveness of TAP block on pain control, its side effects, and parental satisfaction levels in children. Study included patients operated between January 2019 and December 2020 in Gazi University Faculty of Medicine. Total of 97 patients (35 girls, 62 boys) between 5 and 18 years who had an ultrasound guided TAP block for lower abdominal or inguinal surgery were examined retrospectively. TAP block application time, hemodynamic variables, postoperative pain scores, postoperative analgesic requirement, sex, surgical history and satisfaction levels were evaluated. : The average application time of TAP block was 9.48 ± 3.4 and the time between TAP block and surgical incision was 12.06 ± 6.1 min. Pain scores in postanesthesia care unit (PACU) and at the postoperative first hour decreased as the time between TAP block and surgical incision increased (p < 0.05). Girls have higher pain scores at PACU than boys (p < 0.05). Previous surgical history increased postoperative 1st hour pain scores (OR: 13.8; 95% CI 1.7-113.3; p = 0.01). There was a significant negative correlation between pain scores at PACU, postoperative 1st, 2nd, 4th, 6th, 12th and satisfaction levels (r = -0.45, r = -0.56, r = -0.60, r = -0.54, r = -0.52, r = -0,43, respectively, p < 0.05). Ultrasound-guided TAP blocks can be performed safely in children in lower abdominal surgeries. However, the efficacy of TAP block on late term postoperative pain scores is limited. Time interval between the TAP block and the incision, sex, and pain memory, as well as other factors that may improve the quality of TAP block should be considered.

Межфасциальная блокада поперечного пространства живота у пациенток пожилого и старческого возраста в программе ускоренной реабилитации после гинекологических операций

Objective. To study the efficacy of interfascial transversus abdominis plane (TAP) block in elderly and senile patients as an element of complex perioperative anesthesia in a gynecology clinic. Patients and methods. The study enrolled 72 patients aged 61–78 years with benign ovarian tumors classified as anesthesia risk groups 2 and 3 according to the grading system of the American Society of Anesthesiologists (1991). The study group randomly included 35 women and the comparison group included 37 women. In the study group, after induction of anesthesia prior to skin incision, an interfascial injection of 2% ropivacaine solution into the rectus sheath under ultrasound control was performed simultaneously with bilateral subcostal TAP block. A total of 140–180 mg of ropivacaine was used. The abovementioned anesthesia was not administered in the comparison group. Results. Within 2 hours after surgery, the pain score on the visual analogue scale was 1.9 (0.2; 2.7) in the study group and 4.9 (3.3; 5.7) in the comparison group. The situation remained unchanged after 6 hours. In none of the observations in the study group was there an indication for opiates to relieve pain. In the comparison group, 14 patients required opiates once or twice during the first day. Conclusion. The use of interfascial plain block in gynecological practice is a promising element of complex anesthesia in the perioperative period.

Ultrasound-guided Transversus Abdominis Plane Block for Postoperative Analgesia in Patient Undergoing Inguinal Hernia Repair

Background: The Transversus Abdominis Plane (TAP) block technique is one method for inhibiting abdominal pain stimuli by blocking afferent nerves in the abdominal wall via the Petit triangle. TAP block action is frequently performed as a postoperative procedure, such as in the case of hernia repair. The goal of using ultrasound in TAP blocks is to distribute the anesthetic agent accurately in the appropriate neurovascular plane. Case: A 66-year-old male geriatric patient with an incarcerated right inguinal hernia and a history of Hypertensive Heart Disease (HHD) was seen. The patient complained of right groin pain that spread to the right side of the abdomen. Based on the Electrocardiogram (ECG), atrial fibrillation was identified as slow ventricular response and Left Ventricular Hypertrophy (LVH). Chest X-ray revealed cardiomegaly with LVH configuration. ASA III E was assigned to the patient. Regional Anesthesia Subarachnoid Block (RASAB) was used to perform an emergency hernia repair using a regimen of Bupivacaine heavy 0.5% 7.5 mg with adjuvant Fentanyl 50 g. Bilateral TAP block administration using Ropivacaine regimen 0.25% of the total volume of 30 ml was given as postoperative analgesia management. Hemodynamic monitoring, complications and postoperative pain scale were carried out in the High Care Unit (HCU). Hemodynamically stable, pain scale was 1-2 at 24 hours postoperative and no complications. Conclusion: TAP block is provide an effective and safe anti-pain effect in patients undergoing hernia repair with geriatric comorbidities and a history of HHD, as well as to prevent cardiovascular complications and to speed up postoperative patient mobilization.
