Bupivacaine In Transversus Abdominis Plane Block Research Articles

Comparative Study between Fentanyl and Dexmedetomidine as Adjuvants to Bupivacaine 0.5% in Ultrasound-Guided TAP Block for Postoperative Pain Management after Elective Cesarean Section

Abstract Background Analgesia is very important after cesarean section because it improves ambulation and enables the mother to give optimal care for the neonate in the immediate postoperative period. Opioids are widely used, but their side effects limit their application. Transversus abdominis plane (TAP) block has been proved to be a useful and safe alternative technique to provide analgesia following abdominal surgeries. Objective to compare the duration of analgesia produced by two drugs fentanyl and dexmedetomidine as adjuvants to bupivacaine in TAP block under ultrasound-guidance after cesarean section in a randomized controlled trial. Patients and Methods In our study, 40 patients were randomly divided into 2 equal groups. The control group received 50 mcg of fentanyl added to bupivacaine on each side. The study group received 50 mcg of dexmedetomidine added to bupivacaine on each side. All patients received equal volumes. Our study showed that addition of a 50 mcg of dexmedetomidine to bupivacaine in ultrasound-guided TAP block has statistically significant effect on the hemodynamic stability of the patients. In addition, dexmedetomidine prolonged the duration of analgesia significantly, as proved by the time of request of first rescue analgesia. Moreover, in dexmedetomidine group, postoperative analgesic requirements were greatly lesser than that of fentanyl group. This makes dexmedetomidine with bupivacaine more superior than the use of fentanyl with bupivacaine. Results In our study, the total rescue analgesia consumed in 24 h postoperatively which was pethidine was less in the TAP-D group (75 ± 25.6 mg) than in the TAP-F group (112.5 ± 42.5 mg). In this study, regarding the measurement the time to the first dose of analgesic received postoperatively, there was a long duration needed in TAP-D group compared to the TAP-F (control group) with the p- value < 0.0001. The time to the first rescue analgesia in the TAP-D group was (659.7 ± 20.99 min.) and for the TAP-F group, it was (512.75 ± 18.1 min.). Conclusion Dexmedetomidine delayed the time to first rescue analgesia when added to bupivacaine in TAP block using ultrasound-guided technique and improved patients’ outcome with decrease in the total pethidine consumption and more hemodynamic stability in comparison to the addition of fentanyl to bupivacaine.

The Cost-effectiveness of Enhanced Recovery after Surgery Protocols in Abdominally Based Autologous Breast Reconstruction.

The purpose of this study was to conduct a systematic review on the cost-effectiveness of enhanced recovery after surgery (ERAS) protocols in abdominally based autologous breast reconstruction. Further, we reviewed the use of liposomal bupivacaine transversus abdominis plane (TAP) blocks in abdominal autologous reconstruction. PubMed, Embase, Cochrane, and Scopus were used for literature review, and PRISMA guidelines were followed. Included articles had full-text available, included cost data, and involved use of TAP block. Reviews, case reports, or comparisons between immediate and delayed breast reconstruction were excluded. Included articles were reviewed for data highlighting treatment cost and associated length of stay (LOS). Cost and LOS were further stratified by treatment group (ERAS versus non-ERAS) and method of postoperative pain control (TAP versus non-TAP). Incremental cost-effectiveness ratio (ICER) was used to compare the impact of the above treatments on cost and LOS. Of the 381 initial articles, 11 were included. These contained 919 patients, of whom 421 participated in an ERAS pathway. The average ICER for ERAS pathways was $1664.45 per day (range, $952.70-$2860). Average LOS of ERAS pathways was 3.12 days versus 4.57 days for non-ERAS pathways. The average ICER of TAP blocks was $909.19 (range, $89.64-$1728.73) with an average LOS of 3.70 days for TAP blocks versus 4.09 days in controls. The use of ERAS pathways and postoperative pain control with liposomal bupivacaine TAP block during breast reconstruction is cost-effective. These interventions should be included in comprehensive perioperative plans aimed at positive outcomes with reduced costs.

Effectiveness of Liposomal Bupivacaine Transversus Abdominis Plane Block in DIEP Flap Breast Reconstruction: Randomized Controlled Trial.

Transversus Abdominis Plane (TAP) blocks improve pain control and reduce narcotic medication requirements in various surgical procedures. Liposomal bupivacaine may provide more sustained analgesia. This study compares pain related outcomes between standard bupivacaine and liposomal bupivacaine TAP blocks after autologous breast reconstruction. Prospective single-center, single-blinded, randomized controlled trial between March 2021 and December 2022. DIEP flap breast reconstruction patients in a standardized Enhanced Recovery After Surgery (ERAS) pathway were randomized to receive intraoperative TAPs with either bupivacaine / epinephrine (control) or liposomal bupivacaine / bupivacaine / epinephrine (experimental). Primary outcome was postoperative narcotic medication requirements, with secondary outcomes of pain scores, length of stay (LOS), and narcotic medication refills. 117 patients met inclusion criteria (59 control, 58 experimental). Patient demographics, comorbidities, breast pathologic variables, surgery laterality and immediate versus delayed reconstruction status were equivalent between groups. Control group had significantly higher average pain scores postoperatively (4.3 vs. 3.6, p=0.004). However, there were no significant differences in mean narcotic use (66.9 MME vs 60.2 MME, p=0.47). Both LOS and postoperative narcotic prescription refills were equivalent between groups (2.1 vs 2.2 days, p = 0.55, 22% vs 17.2%, p=0.52). Addition of liposomal bupivacaine to standard bupivacaine TAP block mixture in a standardized ERAS protocol did not demonstrate a significant reduction in postoperative narcotic requirements after DIEP flap breast reconstruction compared to standard bupivacaine alone. Patient-reported pain scores, however, were lower among liposomal bupivacaine patients after the initial 24 hours postoperatively and consistent with a longer duration of analgesia.

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.

A comparative study between the use of dexmedetomidine vs. dexamethasone as adjuvants to bupivacaine in ultrasound-guided transversus abdominis plane block for postoperative pain relief in patients undergoing lower abdominal surgeries

Background &amp; objective: Transversus abdominis plane (TAP) block using local anesthetics is associated with relatively shorter duration of action, and thus additional analgesic drugs are required in the postoperative period. We compared the efficacy and duration of postoperative analgesia achieved with using dexmedetomidine or dexamethasone as adjuvants to bupivacaine in TAP block for lower abdominal surgeries.&#x0D; Methodology: We enrolled 45 adult patients aged from 20-60 y, and randomly divided them into three equal groups. Group A received ultrasound guided TAP block with 0.25% bupivacaine 20 ml plus 4 mg dexamethasone on each side. Group B received 0.25% bupivacaine 20 ml plus dexmedetomidine 0.5 µg/kg on each side, and Group C (control group) patients received only 0.25% bupivacaine 20 ml on each side. Postoperative pain was assessed with VAS on arrival in post-anesthesia care unit (PACU), at 2 h, 6 h, 12 h, 18 h, and at 24 h postoperatively. Duration of analgesia was the time from drug injection to the time of first rescue of analgesia was recorded.&#x0D; Results: Mean duration to first dose of rescue analgesia among patients of dexmedetomidine group (Group B) was significantly prolonged as compared to dexamethasone group and bupivacaine only group. Regarding postoperative pain scores there were no statistically significant difference between the three groups; except at 6 h between the A and B groups and the control group. Both dexamethasone group and dexmedetomidine group showed better pain control than bupivacaine only at 6 h interval.&#x0D; Conclusion: Dexmedetomidine added to bupivacaine in ultrasound-guided transversus abdominis plane block for postoperative pain relief in patients undergoing lower abdominal surgeries prolongs the time to initial postoperative pain presented by time to first rescue analgesic demand than dexamethasone added to bupivacaine; the shortest time to first rescue analgesic was observed in bupivacaine alone group.&#x0D; Abbreviations: TAP: Transversus abdominis plane block; LA: Local anesthetic; PACU: Post anesthesia care unit; VAS: Visual Analogue Scale; ASA: American Society of Anesthesiologists; SD: Standard deviation; IQR: Inter quartile range.&#x0D; Citation: Sobhy YS, Gadalla RR, Nofal WH, Saleh MAE, Abdou KM.

Analgesic Efficacy of Dexamethasone and Dexmedetomidine as an Adjuvant to 2% Lignocaine Adrenaline and 0.5% Bupivacaine in Transversus Abdominis Plane Block after Caesarean Delivery

Introduction: The ultrasound-guided Transversus Abdominis Plane (TAP) block is an analgesic technique which involves injection of a local anesthetic between the internal oblique abdominal and the transversus abdominis muscle planes. It provides analgesia to the cranial branches of T10-L1 nerve roots. It has been a practice to provide analgesia in patients following various surgical procedures including the gynecological procedures like hysterectomy and caesarean section. Aim: To assess the analgesic efficacy of dexamethasone and dexmedetomidine as an adjuvant to 2% lignocaine adrenaline and 0.5% bupivacaine in TAP block following caesarean delivery. Materials and Methods: This was a cross-sectional study conducted at Konaseema Institute of Medical Sciences and Research Foundation (KIMS&amp;RF), Amalapuram, Andhra Pradesh, India for a period of one year from January 2021 to December 2021. One hundred patients with an American Society of Anaesthesiologists (ASA) physical scores of I-II, who underwent caesarean section under the Pfannenstiel incision method under subarachnoid anaesthesia with 0.5% heavy bupivacaine, were enrolled in the study. Group I consisted of patients that received an ultrasound-guided bilateral TAP block immediately following surgery with 10 mL of 0.5% bupivacaine, 10 mL of 2% lignocaine with adrenaline, and 20 mcg dexmedetomidine. Group II included patients who received ultrasound-guided bilateral TAP block immediately following surgery with 10 mL of 0.5% bupivacaine, 10 mL of 2% lignocaine adrenaline, and 8 mg dexamethasone. The Electrocardiogram (ECG) recordings and blood pressure were recorded during the block in each patient. This approach enabled a more precise analgesic approach for each individual patient. The patients were assessed for pain up to 12 hours of surgery based on a Visual Analog Scale (VAS), where 0 represented no pain and 10 represented ‘the worst pain ever possible. Results: The patients who received ultrasound-guided TAP block with dexmedetomidine were significantly less on-demand of tramadol (p-value=0.005) and had significantly lower VAS scores at 3 hours (p-value=0,000014), 6 hours (p=0.015) and 12 hours (p-value=0.006), postoperatively. Conclusion: This study proved that dexmedetomidine was more effective when compared to dexamethasone, when added as an adjuvant to 2% lignocaine adrenaline and 0.5% bupivacaine. Ultrasound guided TAP block was a safe and effective postoperative analgesia in cesarean section.

Effect of preoperative versus postoperative use of transversus abdominis plane block with plain 0.25\u2009% bupivacaine on postoperative opioid use: a retrospective study

BackgroundEnhanced recovery protocols optimize pain control via multimodal approaches that include transversus abdominis plane (TAP) block. The aim of this study was to evaluate the effect of preoperative vs. postoperative plain 0.25 % bupivacaine TAP block on postoperative opioid use after colorectal surgery.MethodsA retrospective cohort study comparing postoperative opioid use in patients who received preoperative (n = 240) vs. postoperative (n = 22) plain 0.25 % bupivacaine TAP blocks. The study was conducted in a single tertiary care institution and included patients who underwent colorectal resections between August 2018 and January 2020. The primary outcome of the study was postoperative opioid use. Secondary outcomes included operative details, length of stay, reoperation, and readmission rates.ResultsPatients who received postoperative plain 0.25 % bupivacaine TAP blocks were less likely to require postoperative patient-controlled analgesia (PCA) (59.1 % vs. 83.3 %; p = 0.012) and opioid medications on discharge (6.4 % vs. 16.9 %; p = 0.004) relative to patients who received preoperative TAP. When needed, a significantly smaller amount of opioid was prescribed to the postoperative group (84.5 vs. 32.0 mg, p = 0.047). No significant differences were noted in the duration of postoperative PCA use, amount of oral opioid use, and length of stay.ConclusionsPlain 0.25 % bupivacaine TAP block administered postoperatively was associated with significantly lower need for postoperative PCA and discharge opioid medications. The overall hospital length of stay was not affected by the timing of TAP block. Because of the limited sample size in this study, conclusions cannot be generalized, and more research will be required.

BUPIVACAINE WITH MAGNESIUM SULPHATE VS BUPIVACAINE ALONE IN TRANSVERSUS ABDOMINIS PLANE BLOCK FOR POSTOPERATIVE ANALGESIA IN TOTALABDOMINAL HYSTERECTOMY PATIENTS: A RANDOMISED CONTROL TRIAL.

Background: Postoperative (PO) pain relief following major surgeries had been a challenging task. Adequate pain control is essential for early mobilisation and wellbeing of surgical patients. Incidence of PO pain following abdominal surgeries is higher when transverse lower abdominal incisions are done as in Total Abdominal Hysterectomy (TAH). Performing Transversus Abdominis Plane (TAP) block reduces the PO pain. Various adjuvants like clonidine, epinephrine and magnesium sulphate have been added to local anaesthetics to prolong the duration of TAPblock. The aim of this study was to investigate the effects of adding MgSO4 as an adjuvant to bupivacaine in TAP block for PO analgesia in patients undergoing TAH under spinal anaesthesia. Methods: 100 patients belonging to ASA1 or 2 scheduled for TAH under Sub Arachnoid Block (SAB) were randomly assigned into two groups- BM and B. All patients were given SAB with 15 mg of 0.5% hyperbaric Bupivacaine and TAH was done. USG guided TAPblock was given once SAB sensory level regressed to T8 dermatome. Group BM received 16ml 0.25% Bupivacaine (40mg) with 150 mg magnesium sulphate injected on each side while Group B received 16 ml 0.25% Bupivacaine only. Patients were asked to rate their pain on a 10 cm VAS scale at time 0 (time of completion of TAPblock),2,4,6,12 and 24 hours. Rescue analgesia with Inj. morphine was provided whenever VAS score was &gt; 3. Results: Patients in magnesium sulphate group had prolonged analgesia as compared to the control group. The heart rate and blood pressure response were signicantly lower in that group. Morphine requirement for PO analgesia was also signicantly reduced in group BM. No complications were seen in either group. Conclusion: Adding Magnesium sulphate to Bupivacaine in TAP block in TAH patients prolonged the duration of PO analgesia.

To Compare 0.25% Ropivacaine And 0.25% Bupivacaine In Tap Block For Postoperative Analgesia In Patients Undergoing Abdominal Surgeries.

INTRODUCTION Pain has been defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage.1 Pain is the most dreaded problem which a person fears after any surgery. The transversus abdominis plane (TAP) block is an anaesthesia technique that provides analgesia to the parietal peritoneum as well as the skin and muscles of the anterior abdominal wall.4 Since the thoracolumbar nerves originating from the T6 to L1 spinal roots run into this plane and supply sensory nerves to the anterolateral abdominal wall5, the local anaesthetic spread in this plane can block the neural afferents and provide analgesia to the anterolateral abdominal wall. AIM AND OBJECTIVES Aim of study was to compare 0.25% Ropivacaine and 0.25% Bupivacaine in TAP block for postoperative analgesia in patients undergoing Abdominal Surgeries. The following parameters were compared: A. To study the effectiveness of transverses abdominis plane block for post-operative analgesia in Abdominal Surgeries. B. To compare the duration of analgesia and its effectiveness conferred by 0.25% Ropivacaine and 0.25% Bupivacaine. C. Total requirement of rescue analgesia. D. To watch for occurrence of side effects, if any MATERIALS AND METHODS A comparative clinical study was carried out on 60 adult patients belonging to ASA grade I or II, scheduled for elective Abdominal Surgeries. All patients were administered spinal anaesthesia with bupivacaine heavy 0.5%, 2.0-4.0 ml with 25 G spinal needle at L2-L3 or L3-L4 vertebral interspace. The patients were randomly allocated in two groups and study drug was injected at the end of surgery according to the group. The volume of administered drug kept constant (20 ml). Group I: Patients received TAP BLOCK on each side with 10ml 0.25% Ropivacaine. Group II: Patients received TAP BLOCK on each side with 10ml 0.25% Bupivacaine. CONCLUSION Transversus Abdominis Plane Block (TAP Block) provides better postoperative analgesia in various abdominal surgeries. 0.25% ropivacaine and 0.25% bupivacaine are equally effective in TAP block and provides effective postoperative analgesia but ropivacaine group shown longer duration of action compared to bupivacaine which was statistically significant without causing any increased adverse effects.

The Efficacy of Liposomal Bupivacaine on Postoperative Pain Following Abdominal Wall Reconstruction: A Randomized, Double-blind, Placebo-controlled Trial.

To study the efficacy of liposomal bupivacaine on postoperative opioid requirement and pain following abdominal wall reconstruction. Despite the widespread use of liposomal bupivacaine in transversus abdominis plane block, there is inadequate evidence demonstrating its efficacy in open abdominal wall reconstruction. We hypothesized that liposomal bupivacaine plane block would result in decreased opioid requirements compared with placebo in the first 72 hours after surgery. This was a single-center double-blind, placebo-controlled prospective study conducted between July 2018 and November 2019. Adult patients (at least 18 yrs of age) undergoing open, elective, ventral hernia repairs with mesh placed in the retromuscular position were enrolled. Patients were randomized to surgeon-performed transversus abdominis plane block with liposomal bupivacaine, simple bupivacaine, or normal saline (placebo). The main outcome was opioid requirements in the first 72 hours after surgery. Secondary outcomes included total inpatient opioid use, pain scores determined using a 100 mm visual analog scale, length of hospital stay, and patientreported quality of life. Of the 164 patients who were included in the analysis, 57 patients received liposomal bupivacaine, 55 patients received simple bupivacaine, and 52 received placebo. There were no differences in the total opioid used in the first 72 hours after surgery as measured by morphine milligram equivalents when liposomal bupivacaine was compared with simple bupivacaine and placebo (325 ± 225 vs 350 ± 284 vs 310 ± 272, respectively, P = 0.725). Similarly, there were no differences in total inpatient opioid use, pain scores, length of stay, and patient-reported quality of life. There are no apparent clinical benefits to using liposomal bupivacaine transversus abdominis plane block when compared with simple bupivacaine and placebo for open abdominal wall reconstruction.

Safety and efficacy of dexamethasone as an adjuvant to bupivacaine in bilateral transversus abdominis plane block in children undergoing major abdominal surgery

BackgroundThis prospective randomized controlled double-blind clinical study was conducted on 52 patients of both genders divided into two groups (26 patients each). Local anaesthetic solution of isobaric bupivacaine 0.25% (0.3 ml/kg) was prepared. Group A received bilateral transversus abdominis plane (TAP) block with bupivacaine and dexamethasone (0.3 mg/kg) while group B received bilateral TAP block with bupivacaine and volume of saline equal to the amount of dexamethasone given in group A. Patients were observed for FLACC pain scale at the time of discharge from the post-anaesthesia care unit and then every 2 h for 36 h after the operation. This study was conducted to assess the safety and efficacy of adding dexamethasone to bupivacaine on the quality of bilateral US-guided transversus abdominis plane (TAP) block in children undergoing major abdominal surgeryResultsDexamethasone added to local anaesthetic in ultrasound-guided TAP block significantly decreased FLACC score at 8, 10, and 12 up to 24 h postoperatively, The time to the first requested analgesia was prolonged in the dexamethasone group (P = 0.000). The total dose of acetaminophen consumption over 36 h after surgery was also reduced (P = 0.000), but no difference was found regarding the total dose of rectal diclofenac (P = 0.068).ConclusionAdding dexamethasone to isobaric bupivacaine TAP block reduces postoperative pain and analgesic requirements compared to isobaric bupivacaine TAP block alone in children undergoing major abdominal surgery.

Effect of the Combination of Ketorolac and Bupivacaine on Transversus Abdominis Plane Block for Postoperative Analgesia After Gynecological Laparoscopic Surgery.

BackgroundThis study assessed the additional benefits of bupivacaine when combined with ketorolac for transversus abdominis plane (TAP) block after gynecological laparoscopic surgery.Material/MethodsThis randomized, observer-blind trial recruited 153 patients who underwent gynecological laparoscopic surgery. Patients were randomly assigned to receive bupivacaine combined with ketorolac 15 mg/side for TAP block (TK group), bupivacaine for TAP block and 30 mg postoperative intravenous ketorolac (T group), or 30 mg postoperative intravenous ketorolac alone (C group). The primary endpoints included consumption of sufentanil for 24 h postoperatively, actual press times of the patient-controlled analgesia (PCA) pump, and effective press times of the PCA pump, whereas the secondary endpoints included numerical rating scale (NRS) pain scores at rest and during activity, satisfaction with analgesia, episodes of nausea and vomiting and length of hospital stay.ResultsSufentanil consumption, actual press times of the PCA pump, and effective press times of the PCA pump were lower in the TK and T groups than in the C group. NRS scores at rest and during activity at 1, 2, 4, 6, and 24 hours were significantly lower in the TK and T groups than in the C group. The TK and T groups showed greater satisfaction with analgesia than the C group, while the TK group showed greater overall satisfaction than the C group. Lengths of stay, rates of nausea and vomiting, and venting times did not differ significantly among the three groups.ConclusionsCombined ketorolac and bupivacaine as TAP block improved the effectiveness of analgesia without increasing adverse events.

A Comparative Study Between Magnesium Sulfate Versus Morphine Added to Bupivacaine in Ultra-Sound Guided Transversus Abdominis Plane Block for Post-Operative Analgesia after Inguinal Herniorraphy

Abstract Background Inguinal hernia considered the third common disease in surgeries for adult after acute appendicitis and proctologic disorders. About 20 millions of inguinal hernia repairs are performed globally. Inguinal herniorrhaphy is frequently associated with persistent postoperative pain. A significant proportion of pain experienced by patients undergoing abdominal surgeries is related to somatic pain signals derived from the abdominal wall. Aim of the Work The aim of this study is to assess the postoperative analgesic efficacy of Magnesium sulfate added to Bupivacine verus Morphine to Bupivacaine in ultrasound guided transversus abdominis plane (TAP) block after inguinal herniorraphy regarding the pain relief and the amount of rescue analgesia used postoperative. Patients and Methods The study was conducted on 45 randomly chosen patients in Ain Shams University Hospitals after approval of the medical ethical committee. They were allocated in three groups of 15 patients each: Group - I (B): received TAP block with Bupivacaine only as a “Control Group”. Group - II (B-MO): received TAP Block with Bupivacaine plus Morphine. Group - III (B-Mg): received TAP block with Bupivacaine plus Magnesium Sulfate. The three groups were adequately monitored and assessed intra- and post-operatively and they were compared regarding analgesic outcome by using the visual analogue scaling system, besides, recording time for first call for rescue analgesia and total consumption of it in the 1st 24 postoperative hours. Demographic data and post-operative hemodynamics were also assessed. Results The results of the study revealed that Magnesium added to bupivacaine better than Morphine added to Bupivacaine in transversus abdominis plane block regarding the postoperative analgesia after inguinal Herniorraphy. Conclusion In Conclusion the addition of MgSo4 as an adjuvant to bupivacaine in TAP block has shown superiority over either mono-therapy with bupivacaine or bupivacaine-Morphine combination in many aspects such as postoperative analgesic outcome assessed by VAS score, 1st time of rescue analgesia and without the pronounced side effects of the conventional postoperative opioids and less side effect than Morphine.

Reducing the pain: A cost-effectiveness analysis of transversus abdominis plane block using liposomal bupivacaine for outpatient laparoscopic ventral hernia repair

BackgroundTransversus abdominis plane block with liposomal bupivacaine has been studied as an effective method of reducing the need for postoperative opioids and increasing same-day discharge rates. However, less is known about the cost-effectiveness of this strategy relative to opioids alone for hernia repair. We performed an economic evaluation of these strategies using a computer simulation model. MethodsA decision tree was constructed to determine cost-effectiveness as measured by incremental cost-effectiveness ratios per quality-adjusted life-year. Base-case costs, quality-adjusted life-year values, and probabilities were derived from published studies and Medicare fee schedules. For input parameters for which we could not find values in the published literature, we used expert opinion. A 1-month time horizon was selected to focus on the immediate postoperative period. Finally, we performed 1-way, 2-way, and probabilistic sensitivity analyses. ResultsThe liposomal bupivacaine transversus abdominis plane block was a dominant strategy yielding a $456.75 decrease in cost and an 0.1 increase in quality-adjusted life-years relative to opioids alone. In 1-way sensitivity analysis of cost incremental cost-effectiveness ratio, values were most sensitive to variations in the amount saved by same-day discharge and the cost of bupivacaine. In probabilistic sensitivity analyses, transversus abdominis plane strategy was cost-effective at a willingness-to-pay threshold of $50,000/quality-adjusted life-year in 94.5% of iterations and at a willingness-to-pay threshold of $100,000/quality-adjusted life-year in 97.1% of iterations. ConclusionThe use of liposomal bupivacaine transversus abdominis plane block resulted in cost savings and improved quality-adjusted life-years in base-case analyses and was cost-effective at conventional willingness-to-pay thresholds in the majority of iterations in probabilistic sensitivity analyses.

Analgesic effects of TAP block among open appendectomy patients and the need of postoperative pethidine for Pain Management: A randomised controlled trial

BackgroundThe transversus abdominis plane (TAP) block is an effective method to reduce postoperative pain and need of analgesics following abdominal surgeries. ObjectiveThe aim of this study is to evaluate the effects of Marcaine (0.5% bupivacaine) TAP block on postoperative pain, patient recovery and the need of pethidine as an analgesic, following open appendectomy. MethodIn this randomized blinded study, 96 patients undergoing open appendectomy were randomly divided into two equal groups of 48 patients. Group A received 20 cc of Marcaine (0.5% bupivacaine) under ultrasound guidance as TAP block and group B received 20 cc of normal saline as a control group. Under general anesthesia, patients underwent open appendectomy. The visual analogue scale (VAS) was used to measure postoperative pain along with the patient's need of pethidine, patient's satisfaction, duration of hospitalization, complications and recovery time (time to resume walking). ResultThe two groups were had no statistically significant difference in terms of age, sex and BMI, P < 0.99, respectively. After adjusting the duration of the surgery and incision size, the duration of hospitalization, time of resume walking, patient satisfaction based on postoperative pain and the need of pethidine at 1, 3, 6, 12, 24 and 48 h were significantly different in the two groups, P < 0.001. Additionally, postoperative complications were not significantly different among the two groups. ConclusionThe results of the study indicate that TAP block before open appendectomy with Marcaine (0.5% bupivacaine) is effective to manage postoperative pain and is associated reduced need of postoperative analgesia and hospitalization.

Comparison of Therapeutic Benefit of Bupivacaine HCl Transversus Abdominis Plane (TAP) Block as Part of an Enhanced Recovery Pathway versus Traditional Oral and Intravenous Pain Control after Minimally Invasive Colorectal Surgery: A Prospective, Randomized, Double-Blind Trial

Enhanced recovery pathways (ERPs), when combined with transversus abdominis plane (TAP) blocks, have been proven to reduce the length of stay (LOS) and improve quality outcomes. Nonopioid pain management is an essential component of this pathway, leading to a reduction in immobility, postoperative ileus, and an increase in patient satisfaction. TAP block variations have been studied in general and gynecologic surgery. This study evaluates the effectiveness of laparoscopic TAP blocks in conjunction with the benefit of an ERP. One hundred thirty-seven consecutive laparoscopic and robotic-assisted Colorectal Surgery patients received TAP blocks under laparoscopic guidance while under anesthesia, randomized to a placebo, bupivacaine TAP block, or bupivacaine TAP block with an ERP arm of the trial. Patient demographics, operative techniques, and postoperative outcomes were analyzed using statistical analysis software. Our main objective was to determine short-term benefits of TAP blocks on reducing total narcotic consumption. Secondary objectives included effects of TAP blocks on time to ambulation, time to bowel function, and LOS. To isolate the effect of the TAP blocks, no efforts were made to control nursing or patient education in patients managed without an ERP. Of 137 patients, 14 were withdrawn. All cases were elective, with the main diagnosis colon cancer or dysplastic polyps (47.1%). The median age in each group was comparable (P = 0.12), with female majority in both groups (58.5%). Most procedures were segmental colon resections (74.7%). Thirty-one patients received a placebo, 41 bupivacaine TAP, and 51 bupivacaine TAP plus ERP. In terms of primary endpoints, the bupivacaine plus ERP arm used statistically significant less IV narcotics on postoperative day 1 and in total (P = 0.001, P = 0.008). All patients ambulated on average within the first 24 hours postoperatively, with the TAP plus ERP group approximately 0.5 days sooner (P = 0.001). The TAP plus ERP group also had a return of bowel function and LOS approximately 24 hours early (P = 0.001 and P = 0.001). This study shows that a laparoscopically placed bupivacaine TAP block when used as part of an ERP can reduce LOS, postoperative narcotics, time to ambulation and bowel function, and LOS. Defined pain regimens with auxiliary staff teaching can add to the improvement in quality outcomes in laparoscopic colorectal surgery and, with the addition of the TAP block, can add to patient satisfaction and lower hospital costs.

Transversus abdominis plane block reduces pain and narcotic consumption after robot-assisted distal pancreatectomy

BackgroundMinimizing pain and disability are key postoperative objectives of robot-assisted distal pancreatectomy (RADP). This study tested effects of bupivacaine transversus abdominis plane (TAP) block on opioid consumption and pain after RADP. MethodsRetrospective case-control study (June 2012 -Oct 2017) evaluating bilateral intraoperative bupivacaine TAP block as an interrupted time series. Linear regression evaluated opioid consumption in terms of intravenous (IV) morphine milligram equivalents (MME) and controlled for preoperative morbidity. Secondary outcomes included numerical rating scale (NRS) pain scores. Results81 RADP patients met eligibility, 48 before and 33 after implementation of TAP. Baseline characteristics were equivalent with a trend toward higher age, Charlson comorbidity, and ASA score among the TAP cohort. TAP patients consumed on average 4.52 fewer IV MME than controls during the first six postoperative hours (p = 0.032) and reported lower mean NRS scores at six (p = 0.009) and 12 h (p = 0.006) but not at 24 h (p = 0.129). Postoperative morbidity and lengths of stay (LOS) were equivalent (5 vs. 6 days, p = 0.428). ConclusionBupivacaine TAP block was associated with significant reductions in opioid consumption and pain after RADP but did not shorten hospital LOS consistent with bupivacaine's limited half-life.

Ultrasound-guided transversus abdominis plane block for total abdominal hysterectomy: comparison between magnesium sulfate and dexamethasone as adjuvants

Background Patients undergoing total abdominal hysterectomy (TAH) experience severe pain postoperatively, requiring a multimodal approach to analgesia. The transversus abdominis plane (TAP) block seems to be an ideal approach. This block may be achieved using bupivacaine with adjuvants such as dexamethasone or magnesium sulfate, which were compared in this study. Patient and methods A total of 60 patients subjected to TAH were randomly allocated to receive TAP block using 18 ml 0.25% bupivacaine (45 mg) with 2 ml (200 mg) of magnesium sulfate on either side in group M (n=30), whereas patients in group D (n=30) received 18 ml 0.25% bupivacaine (45 mg) with 2 ml (8 mg) of dexamethasone on either side. The visual analog score was considered as the primary outcome, whereas the secondary outcomes were included time to first analgesic request, the total postoperative opioid consumption, nausea and vomiting score, and patient’s satisfaction. Results Visual analog scores showed significantly higher values at 8 and 12 h in group D. The time to first analgesic request was prolonged with lower opioid consumption and more patient satisfaction in group M. Regarding nausea and vomiting, both groups were comparable. Conclusion Magnesium sulfate as an adjuvant to bupivacaine in TAP block for TAH provided better analgesia compared with dexamethasone.

Dexmedetomidine in a surgically inserted catheter for transversus abdominis plane block in donor hepatectomy: A prospective randomized controlled study.

Background:Transversus abdominis plane (TAP) block is a promising technique for analgesia after abdominal surgery. This prospective, randomized controlled trial assessed the effect of adding dexmedetomidine to bupivacaine in TAP block for donor hepatectomy. We hypothesized that this would improve postoperative morphine consumption and reduce analgesia related complication and inflammation.Methods:A total of 50 donor hepatectomy were enrolled in this study. Patients divided into two equal groups according to drugs used for TAP block. Group (B) received 20 ml of bupivacaine hydrochloride 0.25%, Group (BD) received 20 ml of bupivacaine hydrochloride 0.25% and 0.3 μg/kg dexmedetomidine, on both sides at the end of surgery and every 8 h for 48 h at right side only through inserted catheter. Primary outcome objective was morphine consumption at first 72 h. Secondary outcome objectives were morphine requirement, numbers of intake, time to first intake, pain score numerical analog scale (NAS), postoperative analgesia related complications, recovery of intestinal motility, and inflammatory markers.Results:Data were analyzed, rescue morphine analgesia was significantly lower in (BD) group compared with (B) groups as considering total morphine consumption (B 4 ± 1.9, BD 1.5 ± 0.5, P = 0.03), numbers of morphine intake (P = 0.04), morphine requirement (P = 0.03), and first time of analgesia intake (P = 0.04). NAS was significantly lower in group (BD) compared with group (B) group in the first 12 h (NAS 0 - P = 0.001, NAS 1 - P = 0.03). Adding dexmedetomidine improved gut motility, first oral intake without detectable anti-inflammatory effect.Conclusion:Adding dexmedetomidine to bupivacine in a surgically inserted catheter for TAP block in donor hepatectomy reduced morphine consumption without detectable anti-inflammatory effect.
