246.2: Effect of ultrasound guided erector spinae block for post-operative analgesia in renal transplant recipient.

A Randomized clinical trial comparing the efficacy of ultrasound-guided erector spinae block and paravertebral block in preventing postherpetic neuralgia in patients with zoster-associated pain.

The treatment for postherpetic neuralgia (PHN) continues to be challenging in clinical pain management. Paravertebral block (PVB) and erector-spinae block (ESPB) are two novel techniques for treating this distressing condition. We aimed to assess the effectiveness of PVB and ESPB in preventing the progression to PHN in patients with acute herpes zoster (AHZ). Sixty patients in pain due to AHZ were selected for a prospective randomized control study after approval from Institutional Ethical Committee. Written informed consent was taken. Patients were randomized and allotted into Control-group: standard treatment (oral antivirals, analgesics, neuropathic medicines); PVB-Group: standard treatment with PVB and ESPB- Group: standard treatment with ESPB. Under ultrasound guidance, both blocks were administered with 20 ml of 0.25% bupivacaine + dexamethasone 8 mg. Efficacy was evaluated on the 15th, 30th, and 60th day post treatment. The primary endpoint was the proportion of patients with adequate relief from pain and allodynia post study. The incidence of PHN post study was 45% in the ESPB group and 40% in the PVB group and 80% in the control group (p = 0.022). The proportion of patients with pain relief was higher among the PVB group compared to the ESPB group but not statistically significant (p 0.749). On day 60, the mean pain score was 2.45 (±3.05) and 2.15 (±2.7) in ESPB and PVB groups, respectively, and 4.3 (±2.27) in the control group (p 0.003). PVB and ESPB are effective approaches in treating patients suffering from pain due to acute zoster and help in preventing its progression to PHN.

Changes in motor evoked potentials after erector spinae block in scoliosis surgery-when to take pre-incision baseline recordings?

Multimodal intraoperative neurophysiological monitoring (IONM) is highly valuable in scoliosis surgeries for monitoring spinal cord function, particularly during instrumentation. Accurate timing of baseline recordings of TcMEP and SSEP is crucial, as any changes observed during surgery and instrumentation are compared to these baseline recordings. However, the impact of ultrasound-guided erector spinae block (USG-ESPB) on SSEP and TcMEP is not well-studied in scoliosis surgery. In this report, we present two cases of scoliosis surgery where bilateral two-level USG-ESPB using different concentrations of ropivacaine (0.375% and 0.2%) resulted in a transient and significant deterioration of TcMEP, occurring 3 minutes after the block and lasting for 20 minutes. Remarkably, SSEPs remained unchanged during this period. These findings suggest that USG-ESPB may produce TcMEP changes, highlighting the importance of carefully considering the timing of baseline TcMEP acquisition in scoliosis surgery.

Comparison of analgesic efficacy of ultrasound-guided erector spinae block with port site infiltration following laparoscopic cholecystectomy

ABSTRACT Background One of the foremost common medical reasons for delayed discharge following ambulatory surgery is pain. Erector spinae plane block (ESPB) is a comparatively new technique utilized for intra‑ and post‑operative analgesia. We aimed to compare the analgesic efficacy of ESPB with port site infiltration in laparoscopic cholecystectomy (LC) patients. Methods Forty-four patients 18–60 years old with body mass index (BMI) of 18–35 kg/m2 who were scheduled for laparoscopic cholecystectomy were randomized into two groups (22 patients each) either to obtain an ultrasound‑guided Bilateral ESPB (group A) or port‑site infiltration of local anesthetic (group B) after anesthesia induction. The primary outcome was the total postoperative nalbuphine consumption in the first 24 h. Results The overall amount of rescue analgesia was significantly lower in group A (8.27 ± 1.12 mg for nalbuphine as first-line rescue analgesic and 10 patients needed ketorolac as second line rescue analgesic) than in group B (15.92 ± 2.11 mg for nalbuphine as first-line rescue analgesic and 22 patients needed ketorolac as second-line rescue analgesic) during the first 24 h postoperatively. The time to first analgesic request showed statistically significant difference between the two groups with longer time in group A (p value < 0.001). The numerical rate score at rest and when coughing was significantly lower in group A than group B. Conclusion Erector spinae plane block was superior to port site infiltration regarding decrease in analgesic consumption and prolongation in time of postoperative rescue analgesia in patients undergoing laparoscopic cholecystectomy.

Comparison of Efficacy of Erector Spinae Plane Block with Paravertebral Block for Postoperative Analgesia in Patients Undergoing Breast Cancer Surgery

Background: Patients undergoing modified radical mastectomy (MRM) experience acute pain. Inadequate acute postoperative pain control may lead to anxiety, hemodynamic imbalance and development of chronic pain syndrome. Hence analgesia is extremely important for favourable outcome. This study was undertaken to compare the efficacy of ultrasound guided thoracic paravertebral block (TPVB) versus ultrasound guided thoracic erector spinae plane block (ESPB) with clonidine as an adjuvant to local anaesthetic for post-operative analgesia in modified radical mastectomy. Method: This prospective randomized interventional comparative trial, involving 60 patients were undergoing modified radical mastectomy for breast cancer surgery, was conducted in a tertiary care teaching hospital over 18 months. Sixty patients undergoing MRM for breast cancer under general anaesthesia were enrolled. The patients were randomly allocated into one of the two groups. Group E received ultrasound guided erector spinae block and Group P received Paravertebral block at the level of 4th thoracic vertebra (T4). Both the groups were given 21 mL of 0.5% ropivacaine and 1 μg/kg of clonidine diluted in 1 mL of saline (making total volume of up to 22 mL). Primary outcome measure was to compare duration of analgesia, that is from the time of block administration till the time to first rescue analgesia demanded by the patients. Secondary outcome measures were mean visual analogue scale (VAS) score at rest as well as during abduction of ipsilateral arm at various time points, total intraoperative fentanyl and tramadol requirement up to 24 hours postoperatively; postoperative nausea and vomiting; patients satisfaction at the end of 24 hours postoperatively. Statistical method used: Quantitative variables were compared using Independent t-test/Mann-Whitney Test (when the data sets were not normally distributed). Qualitative variables were compared using Chi-Square test /Fisher’s exact test. A p value of &lt;0.05 was considered statistically significant. Results: Duration of analgesi, that is, time of first rescue analgesia from the administration of the block was comparable between the two study groups. The mean (SD) duration of analgesia in group E was 22.78 (3.31) hours and in group P was 22.88 (3.34) hours (P = 0.914). Both the groups were comparable in terms of fentanyl requirement and total 24 hours tramadol requirement Other parameters like postoperative nausea vomiting, effect on hemodynamic and overall patient satisfaction were also comparable between the two groups. Conclusions: Both ultrasound guided ESPB and TPVB are equally efficacious in providing postoperative analgesia in patients undergoing modified radical mastectomy.

Evaluation of the effect of dexmedetomidine versus magnesium sulphate as an adjuvant to bupivacaine in ultrasound guided erector spinae block; a prospective randomized trial

Background &amp; Objectives: Since the introduction of erector spinae plane block (ESPB) in 2016 it has been used with success in various thoracic, abdominal, and spine surgeries. Spine surgeries result in significant postoperative pain. Postoperative opioids provide adequate pain control in most of the cases, but some patients continue to suffer from uncontrolled pain. Patients receiving multiple doses of opioids suffer from various side effects including postoperative nausea and vomiting, constipation, and delayed ambulation. We aimed to compare effect of dexmedetomidine and magnesium sulfate given as adjuvants with bupivacaine 0.25% for ESPB.&#x0D; Methodology: It was a prospective randomized single-blinded study including 52 patients divided into 2 groups; one receiving ESPB with a combination of bupivacaine 0.25% plus magnesium sulfate and the other receiving the same block with a combination of bupivacaine 0.25% plus dexmedetomidine.&#x0D; Results: The group receiving bupivacaine and dexmedetomidine had a prolonged postoperative analgesia duration as well as a decreased total opioid consumption (P &lt; 0.05) compared to group receiving bupivacaine 0.25% plus magnesium sulfate, but had a significant decrease in intraoperative pulse rate and blood pressure compared to the group receiving bupivacaine 0.25% plus magnesium sulfate (P &lt; 0.05).&#x0D; Conclusion: Although dexmedetomidine results in prolonged postoperative analgesia duration compared to magnesium sulfate when combined with bupivacaine 0.25% in ESPB, its negative effects on hemodynamics should be considered.&#x0D; Trial registration: This trial was registered on clinicaltrials.gov registry (NCT05694897) on 23/1/2023.&#x0D; Abbreviations: ASA: American Society of Anesthesiologist; ESPB: Erector Spinae Block; ERAS: Enhanced recovery After Surgery; SPSS: Statistical Package for Social Sciences; VAS: Visual Analog Score&#x0D; Key words: Erector Spinae Plane Block; Dexmedetomidine; Bupivacaine; Visual Analog Scale&#x0D; Citation: Refaat SA, Abdelmageed WM, Alwedeny HM, Soliman EH, Fouly MA.

Comparative study of the efficacy of ultrasound-guided erector spinae block and oblique subcostal transversus abdominis plane block for postoperative analgesia after laparoscopic cholecystectomy

BackgroundLaparoscopic cholecystectomy has changed the surgical management of cholelithiasis and has become the mainstay of the management of uncomplicated gallstone disease. Adequate postoperative pain relief leading to early ambulation is imperative for patient satisfaction and early discharge of the patient. The use of ultrasound in anesthetic practice has ushered in a new era of ultrasound-guided blocks for postoperative analgesia, replacing the conventional methods. This study compares two modalities of postoperative pain relief, namely the oblique subcostal transversus abdominis plane block and the newer erector spinae plane block for patients undergoing laparoscopic cholecystectomy.ResultsSixty patients between the age group 18 to 75 of ASA grades I, II, and III were enrolled in the study. The erector spinae plane block group showed lower numerical rating scores up to 12 h, a longer time period for the requirement of first rescue analgesic, and lower total analgesic consumption postoperatively compared to the oblique subcostal transversus abdominis plane block group. Both blocks were found to have minimal side effects.ConclusionsThe erector spinae plane block is superior to the oblique subcostal transversus abdominis plane block in that it affords lower pain scores and a longer duration of analgesia and reduces the total analgesic consumption after laparoscopic cholecystectomy.Trial registrationClinical Trials Registry of India/CTRI/2020/10/028603/ registered on 23 October 2020http://ctri.nic.in/Clinicaltrials/rmaindet.php?trialid=47807&EncHid=18303.55562&modid=1&compid=19

Abstract No. : ABS3263: Comparison of efficacy of ultrasound guided pectoral blocks plus serratus anterior plane block versus ultrasound guided erector spinae block with fentanyl group as control for analgesia in patients undergoing off-pump coronary artery bypass Grafting.

Background & Aims:To compare the efficacy of Ultrasound-guided Pectoral block (PECS 1&2) plus Serratus Anterior Plane (SAP) block versusErector Spinae Plane (ESP) block for post-op analgesia in patients undergoing Off-Pump Coronary Artery Bypass Grafting(OPCAB). Postoperative analgesia in terms of Numerical Rating Scale (NRS) pain scores at rest (static) and during movement (dynamic) was taken as the primary outcome. Haemodynamic variations,opioid consumption at 48 hours postoperative, time to mobilisation, level of pain at rest and after mobilisation and complications were noted as secondary outcomes.Methods:81 American Society of Anesthesiologists Grade III and IV patients between 35 -70 years, undergoing off-pump coronary artery bypass grafting were recruited.Patients were randomly allocated into three groups, each with 27 subjects: (Group A: Pectoral +Serratus anterior plane block group; Group B: Erector spinae block group ;Group C: Control group with only intravenous opioids).10 ml of 0.25% Bupivacaine + 1% Lignocaine with adrenaline (1 in 2 Lac)+8 mg dexamethasone was givenultrasound guidedPECS 1 and 2 & SAP- 10 ml; on either side and 30ml on either side for Erector spinae block.Results:ESP block had comparable analgesic profile as PECS +SAPB at rest andduring movement in terms of NRS pain scores. Total perioperative opioid consumption was markedly decreased with the supplementation of newer blocktechniques, and better sedation profile wasobserved. The need for rescue analgesia was markedly reduced in block groups.Haemodynamic variationsduration of postoperative ventilation, ICU and hospital stay were comparable in all the three groups.Conclusion:The study concluded that regional blocks were superior to intravenous fentanyl for postoperative pain relief following cardiacsurgery. The use of narcotics leads to poor pain relief and greater sedation in the postoperative period.

Erector Spinae Plane Block as an Alternative Analgesic Technique in Patients Scheduled for Open Renal Surgery: A Randomized Controlled Study

BACKGROUND: Renal surgeries are accompanied by a moderate to a high degree of intra and postoperative pain. Ultra-sound guided erector spinae plane block (ESPB) represents an alternative method for analgesia in such surgeries as it provides cutaneous and visceral sensory blockade that covers the origin of renal and ureteric pain. Furthermore, it allows the anesthesiologist to limit the use of perioperative opioids and avoiding its possible complications. The use of the ultrasound provides higher safety profile and lower incidence of complication in the block performance. AIM: In this study, the ultrasound-guided ESPB was investigated as an alternative method to decrease the use of perioperative opioids. METHODS: The study was designed to be randomized controlled study. 46 patients undergoing open renal surgeries were included and divided into two groups: The ESPB (E) group and the control (C) group. Each group contained 23 patients. After induction of general anesthesia, all patients received ultrasound guided ESPB. Patients of the E group received 25 ml of bupivacaine 0.25% while patients of the C group received 25 ml of normal saline. For all patients; perioperative opioid consumption, 1st analgesic requirement postoperatively, and post-operative numerical rating scale (NRS) for post-operative pain assessment were recorded and analyzed. RESULTS: As regard the general descriptive data and the duration of surgery, the E and the C groups showed no statistical variations (p ≥ 0.05). The ESPB significantly prolonged the time to the firstly required analgesic medication. The median value was “300 min” in the E group compared to “30 min” the C group” with a highly significant p-value (p &lt; 0.001). The median value of the total morphine consumption in the first 24th h postoperatively was significantly reduced in the E group “9 mg” compared to the C group “18 mg” with p-value (p &lt; 0.001) regarding the median value of the intraoperative fentanyl consumption. Patients of the E group consumed 80 mg of fentanyl compared to 180 mg in the C group with p &lt; 0.001. The NRS showed that the E group had lower degrees of postoperative pain throughout most of the first 24th h postoperatively. This was shown by lower NRS median values in the E group at NRS: 0, 1, and 2 with highly significant p-value (p &lt; 0.001) compared to C group. At NRS (3); there was no statistical significance between the E group and the C group (p &gt; 0.05). Afterward, all the time points showed lower median values of NRS in the E group relative to the C group with a highly significant p-value (p &lt; 0.001) except for the 24th h postoperatively (NRS: 6) which had a p-value (p &lt; 0.05). Furthermore, there were no recorded complications in the two groups. CONCLUSION: Ultrasound-guided erector spinae block prolonged the time of first analgesic requirement by the patient and reduced perioperative opioid consumption. Furthermore, it decreased pain scores in the first 24 h after open renal surgeries and it proved to be a good alternative analgesic technique in open renal surgery.

The Effect of Erector Spinae Block versus Serratus Plane Block on Pain Scores and Diaphragmatic Excursion in Multiple Rib Fractures. A Prospective Randomized Trial.

We aimed to investigate whether ultrasound guided erector spinae plane block and serratus anterior plane block would provide effective and safe analgesia in patients with fracture ribs, and to detect their effects on diaphragmatic excursion in such cases. Prospective double-blind randomized study. Tanta University Hospitals. Fifty adult patients ASA I, II with fracture ribs. Patients were randomized to receive either ultrasound guided erector spinae block (Group I) or serratus plane block (Group II) with injection of 19 ml bupivacaine 0.25% plus 1 ml dexamethasone (4 mg). Pain scores, 24 hour total analgesic requirements, diaphragmatic excursion and incidence of adverse events were recorded. At rest and dynamic pain scores were significantly lower in Group I as compared to Group II from 2 hour up to 24 hour post block [median differences (95% CI): -1 (-0.9999; 0.0002), -1 (-0.9999; 0.0002), -1 (-0.9998; 0.0003), -1(-1.000;-0.000) and -1(-2.0000;-1.0000), -1(-0.9998;-0.0001), -1(-1.0001;-1.0002), -1(-2.000; 0.000), respectively], with a significant reduction in 24 hour opioid consumption in Group I in comparison to Group II (P = .004*). Diaphragmatic excursion showed a significant improvement in Group I when compared to Group II at 2, 6, 12, and 24 hour after the block (P = .024*, .038*, .027*, .042* correspondingly). No adverse events were noted. Both erector spinae block and serratus plane block provided safe and effective pain relief in traumatic rib fractures. Although the erector spinae group displayed significantly reduced pain scores, decreased analgesic needs and improved diaphragmatic excursion as compared to serratus group, nevertheless, this was of no clinical significance.

Clinical efficacy of ultrasound guided bilateral erector spinae block for single-level lumbar fusion surgery: a prospective, randomized, case-control study

BACKGROUND CONTEXTPostoperative experience plays a vital role in patient recovery and does not depend on the type and quality of the surgical procedure alone. Non-opioid therapies have become part of the multimodal analgesic regimen for better pain control and reduced opioid-related side effects. Most recently evolved among these are the regional anesthetic techniques, such as the thoracolumbar interfascial plane (TLIP) block and the erector spinae (ESP) block. PURPOSETo assess the efficacy of ultrasound-guided (US) ESP block for postoperative analgesia after a single level lumbar spine fusion surgery compared with conventional (opioid-based) multimodal postoperative analgesia. STUDY DESIGNA prospective, randomized, controlled, and double-blinded clinical trial. PATIENT SAMPLEA 100 consecutive patients requiring single-level lumbar spinal fusion procedure were randomized into two groups- block (multimodal analgesia with US-ESP) and control (only multimodal analgesia) groups. OUTCOME MEASURESDemographic and surgical data, intra-operative blood loss, duration of surgery, total opioid consumption (TOC) and amount of muscle relaxants used were assessed. Postoperatively, the Numeric pain Rating Scale(NRS), Modified Observer's assessment of Alertness and/or Sedation Scale (MOASS) and Patient satisfaction scores were recorded every 2 hours for the first 6 hours followed by every 6 hours for 24 hours. Continuous variables were analyzed using Student's t-test, and categorical variables were analyzed using either the Chi-square test or Fisher's exact test. p-value < .05 was considered statistically significant. METHODSPatients in both groups underwent the identical protocol for pre-emptive analgesia and induction of anesthesia. Patients in the block group received the US-ESP block after induction and positioning, followed by the multimodal analgesia, while the control group received only the multimodal analgesia. RESULTSBoth groups had identical demographic backgrounds and surgical profile. TOC for 24 hours following induction was significantly lower in the block group than the control group (105.0 ± 15.15 vs 158.00 ± 23.38mcg; p < .001). The total muscle relaxant consumption during surgery was also significantly less in the block group than the control group (51.90 ± 3.17 vs 57.70 ± 5.90; p < .001). The intra-operative blood loss was significantly less (p < .001) in the block group (303.00 ± 86.55 ml) than the control group (437.00 ± 116.85 ml). Compared to the block group, the control group's pain score (NRS) was significantly higher in the first 48 hours following surgery. The MOASS score was significantly lower in the control group (4.46 ± 0.50 vs 3.82 ± 0.82; p < .001) in the immediate postoperative period. The satisfaction score was significantly higher in the block group than the control group (9.52 ± 0.65 vs 8.22 ± 0.79; p < .001). CONCLUSIONThe employed US-ESP block for single-level lumbar fusion surgery is an effective component of multimodal analgesia for reducing blood loss, total opioid consumption, and related side effects with a significant reduction of postoperative pain and higher patient satisfaction.

Efficacy of ultrasound-guided erector spinae plane block following breast surgery - A double-blinded randomised, controlled study.

Background and Aims:Regional anaesthesia has been used to reduce acute post-operative pain as well as opioid-related side effects in breast cancer surgery. Erector spinae plane (ESP) block is a relatively new fascial plane block being tried in various surgical procedures. Our study is a double-blind randomised trial, designed to prove the efficacy of this block in breast surgeries.Methods:Seventy female patients scheduled for unilateral breast surgery were enroled in this prospective, randomised, double-blind study. Patients were randomised to group A and group B. All patients received general anaesthesia while group B received additional ultrasound-guided erector spinae block given at thoracic level—T5 with 20ml of 0.25% bupivacaine. Time to first rescue analgesia was the primary outcome. Secondary outcomes were total intraoperative opioid consumption, pain scores over 24 h, post-operative nausea and vomiting and patient satisfaction score at discharge. The Shapiro–Wilk test was used to check the normality of each variable. A comparison was done using Mann–Whitney test and the level of significance was set at 0.05.Results:The median time to first rescue analgesia in group A versus group B was 1 h (1–12h) versus 8 h (1–26h), respectively, with a P value of 0.044. Group B patients had lower pain scores post-operatively and better satisfaction scores at discharge. There was no statistically significant difference in intraoperative fentanyl consumption.Conclusion:Ultrasound-guided ESP block with general anaesthesia offers superior post-operative analgesia compared to general anaesthesia alone in patients undergoing unilateral nonreconstructive breast cancer surgeries.

BACKGROUND Erector spinae block is a paraspinal, fascial block that targets the ventral, dorsal rami and rami communications of spinal nerves. The present study was conducted to know the efficacy of ultrasound guided erector spinae block (ESP) block in preoperative analgesia among patients with percutaneous nephrolithotomy (PCNL) attending a tertiary care hospital. METHODS The study was carried out on 596 patients from Jan 2015 to Jan 2020 who were indicated for PCNL. They were divided into two groups, group A (ESP = 373) and group B (intravenous-IV analgesia = 273). In the group A (N = 373), after induction of general anaesthesia, ESP block with 0.5 % bupivacaine and 1 / 200,000 epinephrine (single shot) was given at lower thoracic level (T10 - 12) and IV analgesia was given in group B. All patients were monitored for supplemental opioid requirement intraoperatively as assessed by their haemodynamic status (baseline change in heart rate-HR &amp; mean arterial blood pressure-MAP). The primary outcome of the study was consumption of tramadol in 24 hrs. Pain assessment every 2-hour pre- and post-operatively using numerical rating (NR) scale was considered as the secondary outcome. Categorical outcomes were compared between study groups using chi-square test / Fisher's exact test; Pvalue of &lt; 0.05 was considered statistically significant using IBM SPSS. RESULTS Most of them in group A were free of pain for 24 hours postoperatively with numerical rating scale score of &lt; 3 and did not require any postop rescue analgesics. Only 1 patient showed numerical rating scale score of 4 around 16 hrs. after the surgery and was given tramadol. Supplemental opioid analgesic was not required by any of the patients during the entire intraoperative period. CONCLUSIONS ESP block is a favourable technique that results in very good analgesic effect preoperatively and also lessens the use of intravenous opioids and other analgesics.

Study of efficacy of ultrasonography guided erector spinae plane block for abdominothoracic surgeries

Background: Erector spinae block (ESPB) provides analgesia by targeting the dorsal and ventral rami of the spinal nerves,performed in the lumbar region for postoperative analgesia of abdomino-thoracic surgeries. This study was aimed to assess the efficacy of Erector spinae block (ESPB) on postoperative analgesia in patients undergoing abdominothoracic surgeries under general anesthesia. Material and Methods: Present study was prospective, randomized, comparative study, conducted in patients with 18-70 years age, ASA grade- I/II, posted for abdominothoracic surgeries, Mallampatti scores - I and II, consented for participation. 120 patients were randomly assigned into two groups of 60 each, to either Erector spine block group (Group 1) or conventional pain killers (Group 2). Results: General characteristics such as age, height, weight, BMI were comparable in both groups and difference was not statistically significant. The postoperative systolic blood pressure, diastolic blood pressure, heart rate and Mean post-operative VAS score difference was statistically significant, from 30 minutes post-operative to 480 mins (8 hours). Group 1 have significantly less amount opioid requirement as none of the patients required inj tramadol more than 100 mg and only 5 (8.33%) cases required 100 mg whereas in the Group 2 73.33% required inj tramadol more than 100 mg and 8.55% required 175 mg. Group 1 have significantly long period of opioid free time as during first 2 hours none of the patients required inj tramadol whereas in the Group 2 83.33% required inj tramadol in the first 2 hours. Conclusion: In our study we concluded that the analgesic efficacy of Ultrasound guided Erector spinae block is an effective procedure over systemic analgesics and provide better patient satisfaction and compliance

Analgesic efficacy of ultrasound-guided erector spinae block and pectoral nerve block in patients undergoing modified radical mastectomy: A randomized control trial

Background and Aims: Modified radical mastectomy (MRM) is the commonest surgical procedure performed for carcinoma breasts. MRM is associated with considerable postoperative pain. This study was aimed to compare the analgesic efficacy of erector spinae plane (ESP) block and pectoral nerve (PECS) block. Materials and Methods: A total 70 female patients, American Society of Anesthesiologist Physical Status I-II, aged between 18 and 65 years, undergoing MRM surgery. Patients were randomly divided into two equal groups of 35 each, by computer-generated random number table. Group E patients, received ESP block with 20 mL of 0.25% levobupivacaine, and Group P patients, received PECS block with 30 mL of 0.25% of levobupivacaine. The surgical procedure was conducted under general anesthesia in both groups. The primary objective was total morphine consumption in the first 24 h and secondary objectives were intraoperative fentanyl needed, duration of analgesia, numeric rating scale (NRS) score, postoperative complications, and patient's satisfaction. The Statistical Package for the Social Science (SPSS) software version 22.0 used for statistical analysis. Results: Demographic data, hemodynamic parameters, and intraoperative fentanyl consumption were comparable between the two groups (P > 0.05). Postoperative morphine consumed in the first 24 h was less in the Group P compared to Group E (P = 0.018). The duration of analgesia was significantly prolonged in the Group P than Group E (P Conclusion: The PECS block is more effective analgesic modality compared to ESP blocks in patients undergoing MRM surgeries.

Ultrasound-guided erector spinae block versus mid-transverse process to pleura block for postoperative analgesia in lumbar spinal surgery.

In recent years, promising results were achieved with the use of ultrasound (US)-guided interfascial plane blocks for effective postoperative analgesia in several surgeries. Erector spina plane (ESP) block and mid-transverse to pleura plane (MTP) block are the latest techniques in this area. The aim of this prospective and randomized study was to compare the postoperative analgesic efficacy of bilateral ESP and MTP blocks in patients undergoing lumbar spinal surgery under general anesthesia (GA). Atotal of 120 adult patients were included in the study and randomized into 3groups: group ESP (n = 40), group MTP (n = 40) and group Control (n = 40). The patients in the group ESP received abilateral block by injecting 20 ml of 0.25% bupivacaine at avertebrae level in the mid-point of the incision before GA. The same LA was administrated bilaterally at the T12/L1 level in the group MTP. Postoperatively, amultimodal analgesic regimen including an intravenous tramadol patient-controlled analgesia (PCA), paracetamol and dexketoprofen was used in all groups. Postoperative pain was assessed using avisual analogue scale (VAS) during the first 48 postoperative hours. Pethidine was used as arescue analgesic when VAS score was >3. Primary outcome measure was mean pain scores. Secondary outcome measures were consumption of rescue analgesic and the amount of tramadol delivered by PCA. A p < 0.05 was considered statistically significant. Mean VAS scores were significantly higher in the group Control than in the group MTP and group ESP at all-time points during 48 h (Control > MTP > ESP; p < 0.001). Mean VAS scores were lower in group ESP than group MTP in postoperative 12h (p < 0.001). Rescue analgesic consumption, number of bolus demand on PCA, PCA bolus demand dose, total PCA dose, and complications related to opioid consumption were highest in control group and lowest in ESP group (Control > MTP > ESP; p < 0.001). Both ESP and MTP blocks provided effective pain relief after lumbar spinal surgery but the ESP block was superior to MTP block regarding postoperative analgesia in the first 24 h.

Ultrasound-guided erector spinae block for postoperative analgesia in thoracotomy patients: a prospective, randomized, observer-blind, controlled clinical trial

Background and objectivesThoracotomy is considered the most painful of surgical procedures and providing adequate analgesia is the onus for all anaesthesiologists. This study investigated the efficacy of the ultrasound-guided erector spinae plane (ESP) block in analgesia after thoracotomies.Patients and methodsSixty patients with American Society of Anesthesiology physical status (ASA-PS) I–IV, aged more than 18 years were allocated to two groups, ESP group which received the ESP block and C (control) group with no block. Single-shot U/S-guided ESP block with 20 ml 0.25% bupivacaine at the 5th thoracic vertebral level was performed preoperatively in the ESP group. Postoperative 24 h morphine consumption and pain scores were compared between the groups. Also, the side effects of opioid usage were compared.Main resultsPostoperative morphine consumption was 22.06 ± 6.24 mg in the ESP group and 30.6 ± 6.23 mg in the C group (p < 0.001). Results showed that there was a significant difference between both groups in favour of the ESP group regarding visual analogue score (VAS) at rest and with coughing (p < 0.001).ConclusionOur study findings show that US-guided ESP block exhibits a significant analgesic effect in patients undergoing thoracotomy surgery.Trial registrationClinicalTrials.gov, NCT03749395.

Comparison between the ultrasound-guided erector spinae block and the subcostal approach to the transversus abdominis plane block in obese patients undergoing sleeve gastrectomy: a randomized controlled trial.

Pain control in the morbidly obese has presented as an anesthetic challenge. The aim of this study is to assess the analgesic efficacy of ultrasound guided bilateral erector spinae block compared to bilateral subcostal transversus abdominis plane block. A prospective randomized, double-blinded controlled study was conducted at Kasr Alainy Hospital on 66 patients scheduled for laparoscopic sleeve gastrectomy. Patients were randomly allocated into three groups and received general anesthesia: bilateral erector spinae block at the level of T9 or bilateral subcostal transversus abdominis block or opioid analgesia (control group). The primary outcome was pain assessment by Visual Analogue Scale. Visual Analogue Scale was lower in the erector spinae and transversus abdominis groups compared with the control group throughout the first 12 postoperative hours (P≤0.001). Visual Analogue Scale was lower in the erector spinae group in relation to control group at 18 postoperative hours (P=0.034). Visual Analogue Scale in the erector spinae group was significantly lower compared to transversus abdominis at the 12 postoperative hours. Twenty-four-hour postoperative pethidine consumption was higher in the control group (median 150, IQR 100-200) compared to both erector spinae (median 0, IQR 0-50) and transversus abdominis (median 50, IQR 0-100) groups (P<0.001). Erector spinae group showed less pethidine consumption than transversus abdominis group. Ultrasound-guided single-shot T9 erector spinae plane block lowers postoperative pain scores, and reduces intraoperative and postoperative opioid consumption compared with both the subcostal approach transversus abdominis plane block and the control group in obese patients that had undergone sleeve gastrectomy.

Ultrasound-guided erector spinae block for post-thoracotomy pain syndrome in video-assisted thoracic surgery

This article describes our experience with 5 patients with post-thoracotomy pain syndrome after video-assisted thoracoscopic lobectomies, treated with weekly erector spinae plane block. We injected corticosteroid and local anesthetic. At the end of the treatment period, pain scores decreased significantly. Our experience suggests that erector spinae plane block may have a role in the treatment of post-thoracoscopy pain syndrome.
