Introduction: Ultrasound (USG)-guided Transversus-Abdominis-Plane (TAP) block is recommended due to its safety and reliability. Echogenic needles provide better needle visibility and might result in better postoperative analgesia after USG-guided TAP block. Aim: To compare visibilty and block-characteristics (including postoperative analgesia) of echogenic vs. non echogenic needle for USG-guided TAP block. Materials and Methods: This randomised double-blind study was carried out at King George’s Medical University, Lucknow over a period of one year (November 2018 to October 2019). Seventy patients undergoing abdominal surgeries were enrolled and randomly allocated to one of two groups Group-E (echogenic) and Group-NE (non echogenic). Bilateral TAP block was performed postoperatively in all the patients and 20 mL of 0.25% Bupivacaine was deposited on each side. In Group-E, echogenic needle was used and in Group-NE, non echogenic needle was used for TAP block. Research assistant documented the start and finish time of the block procedure, number of attempts and redirections based on predetermined criteria. Visibility of needle tip and shaft were graded on a 3-point scale based on recorded and de-identified video-clips. Total procedure-time, number of needle redirections and skin punctures, incidence of vascular punctures, Visual Analogue Scale (VAS) scores and rescue analgesia requirement were also noted. Statistical analysis was done using SPSS Version 21.0. Results: Needle visibility on USG was significantly better in Group-E than Group-NE (χ2=57.24, p<0.001). Mean time to reach the TAP plane (t=-16.89, p<0.001) and total procedure time (t=-15.76, p<0.001) were also significantly lesser in Group-E. Mean number of needle redirections (t=-11.21, p<0.001), mean number of skin punctures (t=-2.12, p=0.038) and postoperative VAS scores throughout the study were found to be significantly lesser in group-E as compared to group-NE. Postoperative analgesia required in 24 hour was lesser in group-E and time of first rescue analgesia required was earlier in group-NE (p<0.001). Patients in both the groups were haemodynamically stable throughout the study. Conclusion: Use of echogenic needle for USG-guided TAP block provides much better needle-visibility resulting in better block-performance. It also provided better analgesia in our study as evident by lesser VAS-scores and lesser requirement of rescue analgesia postoperatively. So, use of echogenic needle should be advocated in all the patients undergoing USG-guided TAP blocks provided there are no financial constraints.

Introduction: Transversus abdominis plane (TAP) block is a regional anesthesia that involves the infiltration of local anesthetic in between the internal oblique and transversus abdominis muscle plane. This block provides post-operative analgesia and reduces the requirement of opioids consumption. Objective: To assess the effectiveness of TAP block in providing postoperative analgesia in women undergoing caesarean section. Methodology: This was a hospital based prospective, comparative, cross sectional study conducted in 70 patients from 17th September 2018 to 17th February 2019 undergoing caesarean section under spinal anesthesia. Patients were divided into two groups. Group A patients received TAP block with 0.5% Ropivacaine versus Group B patients received injection paracetamol 1gm intravenous every 8 hourly as a standard and routine analgesic. At the end of the surgery, TAP block was performed by anesthesiologist and assessment of postoperative pain using a visual analogue pain score at every 1 hour, 3 hour, 6 hour, 12 hour and 24 hour by trained staffs at postoperative ward. Then, depending upon the severity of the pain injection fentanyl 1mcg/kg intravenous was given as rescue analgesia. Short assessment of patient satisfaction (SAPS) score was also assessed 24 hours postoperatively. Results: Compared to control group, in women who received TAP block, there was statistically significant reduction in pain at 3 hr, 6 hr, 24 hrs. However at 12 hrs there was no significant difference in the pain score. The cumulative fentanyl requirement was also significantly less in the TAP block group at all the time points.  Conclusion: The TAP block provided highly effective postoperative analgesia following caesarean section and reduces the fentanyl requirement in the first 24 hour.

The Difference

Background: Pain is the commonest symptom encountered postoperatively and hence multimodal analgesia is tried to overcome it. In this study, we have compared bupivacaine and bupivacaine plus clonidine in transversus abdominis plane (TAP) block for postoperative analgesia in patients undergoing lower abdominal surgeries under spinal anaesthesia.Methods: Sixty ASA I and II patients in the age range of 18-60 years undergoing various lower abdominal surgeries were randomly divided into two groups, who were operated after giving spinal block using 2.5 ml of 0.5% hyperbaric bupivacine and 25ug of fentanyl. At the end of surgical procedure tranversus abdominis plane (TAP) block was given by giving 25 ml of injection bupivacaine 0.25% in group I and 25 ml of 0.25% of bupivacaine with 1 ug.kg-1 of clonidine in group II. Quality of analgesia was assessed by visual analogue scale (VAS), categorical pain scoring system and frequency of rescue analgesia given and duration was assessed with the time at which first rescue analgesia was given. Side effects of clonidine such as sedation, bradycardia and hypotension were also noted. The hemodynamic parameters like heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were noted for both the groups.Results: Demographic characteristics like age, weight, sex, ASA class and type of surgeries were comparable in both groups. SBP, DBP and HR were less in group II than in group I and was statistically significant (p-value<0.05). The overall mean VAS score in group I was 3.03 ± 1.57 and group II was 1.72 ± 1.02 with p-value of 0.0005 and hence better quality of analgesia in group II. Categorical pain scoring system also showed statistically better scores in group II than group I. The duration of analgesia which was calculated by mean time for first rescue analgesia in group I was 6.38 ± 2.56 hours and group II was 14.23 ± 4.63 hours with a p-value of <0.0001 and the difference was statistically significant. The mean number of doses of rescue analgesia in group I for the first 24 hours was 1.37 ± 0.89 and in group II was 0.60 ± 0.62 with a p-value of 0.0003 and the difference was statistically significant. Group II patients showed more sedation scores than group I patients (p-value <0.05). None of the patients had any episode of bradycardia or hypotension.Conclusions: Addition of clonidine 1 ug.kg-1 to 25 ml of 0.25% bupivacaine compared to 25 ml of 0.25% bupivacaine alone in tranverse abdominis plane (TAP) block improves quality of analgesia, increases duration of postoperative analgesia and decreases postoperative analgesic requirements with minimal side effects.

AbstractNowadays, there are various methods to manage pain after laparoscopic cholecystectomy. The aim of this study was to compare the effectof preemptive versus postoperative use of ultrasound-guided transversus abdominis plane (USG-TAP) block on pain relief after laparoscopic cholecystectomy. In this single-blinded randomized clinical trial, the patients who were candidates for laparoscopic cholecystectomy were randomly divided into the two groups (n = 38 per group). In the preemptive group (PG) after the induction of anesthesia and in the postoperative group (POG) after the end of surgery and before the extubation, bilateral ultrasound-guided transversus abdominis plane (TAP) block was performed on patients using 20 cc of ropivacaine 0.25%. Both groups received patient controlled IV analgesia (PCIA) containing Acetaminophen (20 mg/ml) plus ketorolac (0.6 mg/ml) as a standard postoperative analgesia and meperidine 20 mg q 4 h PRN for rescue analgesia. Using the numerical rating scales (NSR), the patients’ pain intensity was assessed at time of arrival to the PACU and in 2th, 4th, 8th, 12th, 24th h. Primary outcome of interest is NSR at rest and coughing in the PACU and in 2th, 4th, 8th, 12th, 24th h. Secondary outcomes of interests were the time to first post-surgical rescue analgesic and level of patients’ pain control satisfaction in the first 24 h. The USG-TAP block significantly decreased pain score in the POG compared to the PG, and also the pain was relieved at rest especially in 8 and 12 h (p value ≤ 0.05) after the surgery. Pain score after coughing during recovery at 2, 8 and 12 h after the operation were significantly decreased. (p value ≤ 0.05) The patient satisfaction scores in the POG were significantly higher in all times. There was a statistically significant difference between the two groups in terms of rate of postoperative nausea and vomiting (PONV), indicating that patients in the POG had significantly lower incidences of the PONV compared tothe PG. The time to first analgesic request was significantly shorterin the POG, which was statistically significant (p value = 0.089). There was no statistically significant difference between the two groups in terms of consumption of analgesics. The postoperative TAP block could offer better postoperative analgesia than preepmtive TAP block.

Introduction: Abdominal Hysterectomy (AH) is one of the most common surgeries performed in gynaecology and is associated with a medium to high pain level. Newly discovered peripheral blocks such as Transversus Abdominis Plane (TAP) block and Quadratus Lumborum (QL) block have gained immense popularity as an adjunct to regional and general anaesthesia for postoperative pain management and reducing analgesic requirements. Aim: To compare the analgesic efficacy of QL block with TAP block in patients undergoing total AH. Materials and Methods: This was a double-blinded Randomised Clinical Trial (RCT). The study population comprised of 105 patients posted for elective total AH under spinal anaesthesia. They were randomly allocated into three groups of 35 patients each. Group Q received bilateral QL block with 40 mL of 0.25% bupivacaine divided on either side, Group T received bilateral TAP block with 40 mL of 0.25% bupivacaine divided on either side and in Group C no block was given. Patients were monitored for Visual Analogue Scale (VAS) scores at 0, 15 minutes, 30 minutes, 1st, 2nd, 6th, 12th and 24th hour postoperatively, time for first analgesic requirement, total analgesic requirement in 24 hours and patient satisfaction score after 24 hours and also adverse effects, if any. Data were analysed using Statistical Package For The Social Sciences (SPSS) version 16 (Chicago, IL, USA) with independent t-test and Chi-square test as appropriate. The p<0.05 was considered statistically significant. Results: There were significantly lower VAS scores in group Q than group T at 2nd and 6th hour with p-value of 0.003 and 0.001, respectively. The time for first analgesic was early in group C with mean value of 1.37±0.74 hours and it was 4.63±0.97 hours in group T and 7.77±1.51 hours in group Q. The total analgesic requirement was lesser in group Q when compared to group C and T. Patient satisfaction score was comparable between group Q and T (p=0.97). No significant difference in complications among the three groups was observed (p=0.51). Conclusion: QL block is a better postoperative analgesic technique than TAP block for postoperative analgesia in hysterectomy patients.

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.

Abstract Background Although regional techniques have been suggested more in order to provide postoperative analgesia in inguinal hernia repairs, the ideal method is still controversial. The aim of this study was to evaluate the effect of preemptive transversus abdominis plane (TAP) block, local anesthetic infiltration (LAI) and intravenous dexketoprofen (IVD) on postoperative pain in inguinal hernia repairs. Methods This prospective study included 120 patients with American Society of Anesthesiologists status 1-3 between 18-75 years of age who undergoing elective inguinal hernia surgery under spinal anesthesia. The patients were allocated into three groups: USG-guided TAP block (Group 1, n = 40), USG-guided LAI (Group 2, n = 40) and IVD (Group 3, n = 40) before surgical incision. The mean of tramadol consumption, number of patients in requiring rescue analgesics, duration of postoperative analgesia and complications were recorded for 24 hours postoperatively. VAS scores were evaluated at the 30 minute, 1, 2, 4, 8, 12, 16 and 24th hours. Results There was no significant difference between the postoperative mean tramadol consumption [Group 1: 22.5 mg; Group 2: 20 mg; Group 3: 27.5 (p 0.833)]. The number of patients requiring rescue analgesics was statistically similar (p 0.787). VAS scores at 30. min, 1, 2, 4, 8 and 12 hours were statistically lower in Group 1 than in the other groups (p 0.003, 007, 0013, 0049, 0015, 0021). VAS scores at 30. min and 2. h were lower in Group 1 than Group 2 (p 0.049, 0.037). İn addition, VAS scores at 30 min, 1, 2, 8 and 12 hours were lower in Group 1 than in Group 3 (p 0.003, 0.006, 0.021, 0.017, 0.016). VAS scores at all hours were statistically similar between Group 2 and Group 3. Conclusion This study demonsrated that preemptive transversus abdominis plane block, local anesthetic infiltration or iv dexketoprofen for postoperative analgesia in inguinal hernia repairs had similar effects on postoperative tramadol consumption and number of requiring rescue analgesic patients. However, TAP block provides lower VAS values and excellent analgesia in more patients in the first 24 hours postoperatively.

Abstract Background Inguinal hernia considered the third common disease in surgeries for adults 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. Objectives The aim of this study is to assess the postoperative analgesic efficacy of transversus abdominis plane (TAP) block compared to ilioinguinal/iliohypogastric nerves block after unilateral inguinal hernia repair regarding the pain relief, effect on hemodynamics, requirement of first supplemental doses of analgesia and total number of doses received. Patients and Methods The study was conducted on 70 randomly chosen patients aged 21 to 60 years, American Society of Anesthesiologists (ASA) class I or II scheduled for elective unilateral open inguinal hernia repair under general anesthesia, in Ain Shams University Hospitals after approval of the medical ethical committee. Results The results of the study revealed that there is Patients receiving TAP block had significantly lower pain scores at 4 h and 6 h after operation, delay time for rescue analgesia and decrease total need of analgesic in first 24 h post operative compared with patients who received ilioinguinal/ iliohypogastric nerves block. Conclusion TAP block was effective in reducing postoperative pain scores for 4-6 hours, lowering total 24-h postoperative opioid and analgesic consumption and delaying the need for rescue analgesia after inguinal hernia repair under general anesthesia, compared to ilioinguinal/iliohypogastric nerves block. This technique can be a promising mode of postoperative analgesia when epidural catheter insertion is contraindicated.

Background: The ultrasound guided transversus abdominis plane (TAP) block which provides effective analgesia after lower abdominal surgeries including caesarean section. It is a simple and reliable technique. In this prospective, randomized double-blind study, we determined the efficacy of TAP block using 0.25% Bupivacaine and 0.9N Saline with respect to VAS for pain, postoperative Tramadol consumption and post-operative ondansetron usage.Methods: This study was conducted on 100 adult patients of ASA physical status I and II in the   age group of 18 to 40 years undergoing elective lower segment cesarean section under spinal anaesthesia. Study group received TAP block with 0.25% Bupivacaine and control group received 10 ml of 0.9N saline on each side. Patients were analyzed for postoperative pain by pain score (at rest, on movement, on cough) using VAS was recorded at 0, ½, 1, 2, 4, 6, 12 and 24 hours postoperatively. Need for rescue analgesia was assessed by time to first dose of Tramadol requirement and total dose of Tramadol over 24 hours of postoperative period. Ondansetron (4 mg i.v.) was administered whenever nausea score was more than 2 or the patient vomited. All the data was noted using uniform performs.Results: Patients received TAP block with 0.25% Bupivacaine had better pain scores at first hour of postoperative period during rest, cough and movement which was statistically significant (p<0.0010) in comparison to group B. There was a statistically significant difference (p <0.001) in the requirement of total dose of Tramadol as a rescue analgesia in patients who received transversus abdominis block with 0.25% Bupivacaine (138.77 mg) in comparison with other group(240 mg).The mean time to first request for Tramadol was significantly longer in group A (5.8 hrs)  in comparison to group B (1.93 hrs) with p value <0.001. Patients received TAP block with 0.9N saline needed more dose of Ondansetron, however, the difference was not statistically significant (p >0.001).Conclusions: TAP block using ultrasound provides substantial reduction in Tramadol consumption, time to first dose of rescue tramadol when compared with control group. This study reinforces the recommendation for TAP as a part of multimodal post-operative analgesic regimen.
