Serratus Anterior Plane Blocks for Early Rib Fracture Pain Management

Rib fractures secondary to blunt thoracic trauma typically result in severe pain that is notoriously difficult to manage. The serratus anterior plane block (SAPB) is a regional anesthesia technique that provides analgesia to most of the hemithorax; however, SAPB has limited evidence for analgesic benefits in rib fractures. To determine whether the addition of an SAPB to protocolized care bundles increases the likelihood of early favorable analgesic outcomes and reduces opioid requirements in patients with rib fractures. This multicenter, open-label, pragmatic randomized clinical trial was conducted at 8 emergency departments across metropolitan and regional New South Wales, Australia, between April 12, 2021, and January 22, 2022. Patients aged 16 years or older with clinically suspected or radiologically proven rib fractures were included in the study. Participants were excluded if they were intubated, transferred for urgent surgical intervention, or had a major concomitant nonthoracic injury. Data were analyzed from September 2022 to July 2023. Patients were randomly assigned (1:1) to receive an SAPB in addition to usual rib fracture management or standard care alone. The primary outcome was a composite pain score measured 4 hours after enrollment. Patients met the primary outcome if they had a pain score reduction of 2 or more points and an absolute pain score of less than 4 out of 10 points. A total of 588 patients were screened, of whom 210 patients (median [IQR] age, 71 [55-84] years; 131 [62%] male) were enrolled, with 105 patients randomized to receive an SAPB plus standard care and 105 patients randomized to standard care alone. In the complete-case intention-to-treat primary outcome analysis, the composite pain score outcome was reached in 38 of 92 patients (41%) in the SAPB group and 18 of 92 patients (19.6%) in the control group (relative risk [RR], 0.73; 95% CI, 0.60-0.89; P = .001). There was a clinically significant reduction in overall opioid consumption in the SAPB group compared with the control group (eg, median [IQR] total opioid requirement at 24 hours: 45 [19-118] vs 91 [34-155] milligram morphine equivalents). Rates of pneumonia (6 patients [10%] vs 7 patients [11%]), length of stay (eg, median [IQR] hospital stay, 4.2 [2.2-7.7] vs 5 [3-7.3] days), and 30-day mortality (1 patient [1%] vs 3 patients [4%]) were similar between the SAPB and control groups. This randomized clinical trial found that the addition of an SAPB to standard rib fracture care significantly increased the proportion of patients who experienced a meaningful reduction in their pain score while also reducing in-hospital opioid requirements. http://anzctr.org.au Identifier: ACTRN12621000040864.

Use and Clinical Relevancy of Pericapsular Nerve Block (PENG) in Total Hip Arthroplasty: A Systematic Review and Meta-analysis.

Ultrasound-guided pericapsular nerve group (PENG) block is an emerging regional anesthesia technique that may provide analgesia for patients undergoing total hip arthroplasties (THA). There are clinical studies comparing this fascial plane block to other established methods; however, evidence on the actual efficacy of this block for THA continues to evolve. Available clinical studies conducted over the past 4 years were reviewed to evaluate the analgesic efficacy and effectiveness of PENG block in patients undergoing THAs. A meta-analysis of randomized controlled trials (RCTs) in patients undergoing THA, where PENG block was compared to no block, placebo/sham block (injection with saline), or other analgesic techniques including suprainguinal fascia iliaca block (FIB), or periarticular infiltration (PAI) was performed. Our primary outcome was opioid consumption during the first 24 hours. Secondary outcomes were postoperative rest and dynamic pain scores at 6-12, 24 and 48 hours, block performance time, sensory-motor assessment, quadriceps weakness, the incidence of postoperative falls, first analgesic request, block and opioid-related complications, surgical complications, patient satisfaction scores, postanesthesia care unit length of stay, hospital length of stay, and functional and quality of life outcomes. We included 12 RCTs with a total of 705 patients. Data showed that PENG block decreased 24-hour oral morphine milligram equivalent consumption by a mean difference (MD) of 3.75mg (95% CI: -5.96,-1.54; P =0.0009). No statistically significant differences in rest or dynamic pain were found, except for a modest MD reduction in dynamic pain score of 0.55 points (95% CI: -0.98, -0.12; P =0.01), measured 24 hours after surgery in favor of PENG block. Our systematic review and meta-analysis suggest that PENG block provides better analgesia, measured as MME use, in the first 24 hours after THA, with no real impact on postoperative VAS scores. Despite statistical significance, the high heterogeneity across RCTs implies that PENG's benefits may not surpass the minimal clinically important difference threshold for us to recommend PENG as best practice in THA.

A COMPARATIVE STUDY OF EFFECT OF DEXMEDETOMIDINE AND DEXAMETHASONE AS AN ADJUVANT TO 0.2% ROPIVACAINE FOR ULTRASOUND GUIDED TRANSVERSUS ABDOMINIS PLANE BLOCK FOR INFRAUMBILICAL SURGERIES

Background: The relief of pain and suffering is, and always has been, one of the primary concerns of mankind and one of the prime factors that has influenced the course of history of medicine. Transversus abdominis plane (TAP) block is a regional anaesthetic technique which blocks the abdominal neural afferents by introducing local anaesthetic into the neuro-fascial plane between the internal oblique and the transversus abdominis muscle. Aim: To compare the efficacy of Dexmedetomidine and dexamethasone as an adjuvant to 0.2%ropivacaine in ultrasound guided transverses abdominis plane block in infra umbilical surgeries in terms of, 1. Time to initial postoperative pain. 2. Time to initial rescue analgesia. 3. Quality of block.. 4. Total postop analgesic consumption. 5. Patient satisfaction with regard to pain relief. 6. Post-operative nausea and vomiting. Materials And Methods: We included 80 patients of age between 18-60 years of American Society of Anesthesiologists status (ASA)I and II scheduled for elective infraumbilical surgeries in our study. We randomly allotted these patients into two groups namely Group A and Group B of each. Patients in Group APatients who received transversus abdominis plane block with - 18ml Ropivacaine 0.2%+ 2 ml Dexamethasone 8mg. Patients in Group B received transversus abdominis plane block with-18ml Ropivacaine 0.2%+ 2 ml Dexmedetomidine .This TAP block was given soon after the surgery is completed. The duration of block and regression of sensory block, time for rescue analgesia, degree of sedation, hemodynamic parameters, post operative analgesia and adverse effects were noted. Result: The two groups were comparable on the basis of duration of surgery, site of surgery, ASA and BMI. Heart rates and mean arterial pressure were compared and it was found to be significantly lower in group B compared to group A until initial 5 hours. In our study we found that the visual analogue score at rest and on coughing between groups A and B was statistically insignificant. However, the time to first rescue analgesia (330 mins vs 240 mins) and total analgsic consumption in the 24 hours period post operatively was significantly lesser for group A compared to group B. Ramsey sedation score was significantly higher in group B compared to group A until 8 hourspost operatively. Nausea and vomiting in 3 cases of group A , and 2 cases in group B. No other significant side effects were noted. Conclusion: USG-guided TAP block is an effective and safe adjunct for postoperative analgesia in infra umblical surgeries. Addition of dexamethasone as an adjuvant prolongs the duration and reduces post-operative analgesic requirement in patients significantly more than dexmedetomidine whereas dexamethasone provides better control of the heart rate and mean arterial pressure.

The effect of ultrasound-guided rectus sheath block on postoperative analgesia in robot assisted prostatectomy: A randomized controlled trial.

Postoperative pain continues to represent an important problem even after minimally invasive robotic-assisted laparoscopic radical prostatectomy, which results in discomfort in the postoperative period and sometimes prolongs hospital stays. Regional anesthesia and analgesia techniques are used in addition to systemic analgesics with the multimodal approach in postoperative pain management. Ultrasound-guided fascial plane blocks are becoming increasingly important, especially in minimally invasive surgeries. Another important cause of discomfort is urinary catheter pain. The present randomized controlled study investigated the effect of rectus sheath block on postoperative pain and catheter-related bladder discomfort in robotic prostatectomy operations. This randomized controlled trial was conducted from March to August 2022. Written informed consent was obtained from all participants. Approval for the study was granted by the Clinical Research Ethics Committee. All individuals provided written informed consent, and adults with American Society of Anesthesiologists Physical Condition classification I to III planned for robotic prostatectomy operations under general anesthesia were enrolled. Following computer-assisted randomization, patients were divided into 2 groups, and general anesthesia was induced in all cases. Rectus sheath block was performed under general anesthesia and at the end of the surgery. No fascial plane block was applied to the patients in the non-rectus sheath block (RSB) group.Postoperative pain and urinary catheter pain were assessed using a numerical rating scale. Fentanyl was planned as rescue analgesia in the recovery room. In case of numerical rating scale scores of 4 or more, patients were given 50 µg fentanyl IV, repeated if necessary. The total fentanyl dose administered was recorded in the recovery room. IV morphine patient-controlled analgesia was planned for all patients. All patients' pain (postoperative pain at surgical site and urethral catheter discomfort) scores and total morphine consumption in the recovery unit and during follow-ups on the ward (3, 6, 12, and 24 hours) in the postoperative period were recorded. Sixty-one patients were evaluated. Total tramadol consumption during follow-up on the ward was significantly higher in the non-RSB group. Fentanyl consumption in the postanesthesia care unit was significantly higher in the non-RSB group. Total morphine consumption was significantly lower in the RSB group at 0 to 12 hours and 12 to 24 hours. Total opioid consumption was 8.81 mg in the RSB group and 19.87 mg in the non-RSB group. A statistically significant decrease in urethral catheter pain was noted in the RSB group at all time points. RSB exhibits effective analgesia by significantly reducing postoperative opioid consumption in robotic prostatectomy operations.

Evaluation of the effectiveness and safety of erector spinae plane block during coronary artery bypass surgery: a randomized clinical trial

The search for a method of perioperative pain control after coronary bypass surgery is relevant both from the point of view of safety and effectiveness of the methods used.Aim: To evaluate the hemodynamic changes and effectiveness of erector spinae plane block (ESPB) for off-pump coronary artery bypass surgery.Methodology and research methods. The prospective randomized single-center study included 45 patients equally distributed according to the applied methods of perioperative analgesia into 3 groups: general anesthesia with epidural anesthesia (GA + EA group, n = 15), general anesthesia with ESPB (GA + ESPB group, n = 15) and general anesthesia without any regional anesthesia techniques (GA group, n = 15). Assessment of hemodynamics and severity of pain syndrome was performed during the first postoperative day.Results. The intraoperative dose of fentanyl was 0.4 (0.4–0.5) mg in the GA + EA group, and 0.4 (0.3–0.4) mg in the GA + ESPB group that is significantly less than in the GA group – 1.1 (1.0–1.1) mg (p < 0.001). Postoperatively, the dose of fentanyl was 0.10±0.04 mg in the GA + EA group and 0.23±0.05 mg in the GA group (p < 0.001), whereas in the ESPB group fentanyl was not used. The pain level assessed by the numeric rating scale (NRS) was 3.0 (2.0–4.0) points at one hour after tracheal extubation and 3.0 (0.5–3.5) points at the end of the first day of the postoperative period without difference between the groups. The systemic and pulmonary hemodynamics, respiratory and vasopressor support did not differ as well.Conclusion. The use of regional anesthesia (EA and ESPB) provides similar quality of perioperative analgesia like general anesthesia, but leads to reduction in opioid doses. Postoperatively, the use of ESPB does not lead to a deterioration of the hemodynamic status of the patient.

Pecto-intercostal Fascial Plane Block: A Novel Technique for Analgesia in Patients with Sternal Dehiscence.

Sternal wound complications following sternotomy need a multidisciplinary approach in high-risk postoperative cardiac surgical patients. Poorly controlled pain during surgical management of such wounds increases cardiovascular stress and respiratory complications. Multimodal analgesia including intravenous opioids, non-opioid analgesics, and regional anesthesia techniques, like central neuraxial blocks and fascial plane blocks, have been described. Pecto-intercostal fascial plane block (PIFB), a novel technique, has been effectively used in patients undergoing cardiac surgery. Under ultrasound (US) guidance PIFB is performed with the aim of depositing local anesthetic between two superficial muscles, namely the pectoralis major muscle and the external intercostal muscle. The authors report a series of five cases where US-guided bilateral PIFB was used in patients undergoing sternal wound debridement. Patients had excellent analgesia intraoperatively as well as postoperatively for 24 hours with minimal requirement of supplemental analgesia. None of the patients experienced complications due to PIFB administration. The authors concluded that bilateral PIFB can be effectively used as an adjunct to multimodal analgesia with general anesthesia and as a sole anesthesia technique in selected cases of sternal wound debridement.

Comparison of Postoperative Analgesia Between Intrathecal Nalbuphine and Intrathecal Fentanyl in Infraumbilical Surgeries: A Double-Blind Randomized Controlled Trial.

Spinal anesthesia is a widely used regional anesthesia technique for surgeries below the umbilicus, butpostoperative analgesia is of major concern due to the relatively short duration of the local anesthetic. Various drugs were used as an additive to local anesthetic to prolong the duration of postoperative analgesia. This study aims to compare the efficacy ofnalbuphine and fentanyl as an intrathecal additive along with local anesthetic. A total of 166 patients aged between 18 and 65 years belonging to the American Society of Anesthesiologists(ASA) I and II undergoing elective infraumbilical surgeries were included in the prospective double-blind randomized controlled trial. The patients were allocated into two groups of 83 each. Group N was given 2.5 mL of 0.5% bupivacaine + 1 mg of nalbuphine (0.5 mL), and group F received 2.5 mL of 0.5% bupivacaine + 25 mcg fentanyl (0.5 mL). Both groups were compared for postoperative analgesia, onset and duration ofboth sensory and motor blockade, intraoperative hemodynamics, and side effects. All demographic data, hemodynamic parameters, and side effects were not statistically significant among the two groups. However, other parameters, such as the mean duration of analgesia, which was 267.27 ±172.099 minutes in group N and 161.35 ±14.957 minutes in group F; meantime for the onset of sensory blockade, whichwas 3.94 ±1.769 minutes in group N and 5.94 ±0.929 minutesin group F; onset of complete motor blockade, which was 7.10 ±1.858 minutes in group N and 11.61 ±1.218 minutes in group F; duration of motor blockade, which was 182.57 ±13.011 minutes in group N and 112.53 ±7.389 minutes in group F;and mean time taken for two-segment regression, which was 118.20 ±12.61 minutes in group N and 113.72 ±8.84 minutes in group F, were all comparable between the two groups. Nalbuphine was found to be more efficacious for prolongation of postoperative analgesia with better hemodynamic stability.

Perioperative Pain Management for Thoracic Surgery: A Multi-Layered Approach.

Cardiothoracic surgeries frequently pose unique challenges in the management of perioperative acute pain that require a multifaceted and personalized approach in order to optimize patient outcomes. This article discusses various analgesic strategies including regional anesthesia techniques such as thoracic epidurals, erector spinae plane blocks, and serratus anterior plane blocks and underscores the significance of perioperative multimodal medications, while providing nuanced recommendations for their use. This article further attempts to provide evidence for the efficacy of the different modalities and compares the effectiveness of the choice of analgesia. The roles of Acute Pain Services (APS) and Transitional Pain Services (TPS) in mitigating opioid dependence and chronic postsurgical pain are also discussed. Precision medicine is also presented as a potential way to offer a patient tailored analgesic strategy. Supported by various randomized controlled trials and meta-analyses, the article concludes that an integrated, patient-specific approach encompassing regional anesthesia and multimodal medications, while also utilizing the services of the Acute Pain Service can help to enhance pain management outcomes in cardiothoracic surgery.

The Impact of Regional Anesthesia in Masking Acute Compartment Syndrome after Limb Trauma.

Regional anesthesia has shown to be successful in controlling major pain in trauma patients. However, the possibility of masking acute compartment syndrome (ACS) after peripheral nerve blocks for limb injuries is still controversially discussed. Therefore, we aimed to summarize the current literature regarding this topic to shed light on the impact of peripheral regional anesthesia on the diagnosis of ACS in trauma patients. We searched Pubmed, Google Scholar and the Cochrane Library for literature following the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. The analysis of these reports was included in the context of the current literature concerning this topic. We found no (randomized) studies, and only six case reports dealing with the impact of peripheral nerve blocks and ACS in patients after a limb trauma met our criteria and were included in our review. Only one reported a delay in the diagnosis of ACS. In most of the cases (5 of 6), the breakthrough pain, despite the nerve block, proved to be a good indicator of a developing ACS. However, despite some narrative articles about the topic including some recommendations about the possibly safe use of regional anesthesia techniques for limb trauma, there is still no international consensus and only one national guideline focusing on the possibly safe use of peripheral nerve blocks in trauma patients at risk of ACS. After reviewing the respective literature, we consider that intra-articular analgesia, sensory blocks, fascial plane blocks and low-concentration continuous peripheral nerve blocks are effective for analgesia and a low-risk analgesia tool for trauma and postsurgical patients at risk of ACS due to the fact that they do not lead to a dense block. Finally, we summarized suggestions based on the results of the literature for the different regional anesthesia modalities in these patients in a table to facilitate the use of these techniques.

Factors influencing decision-making for the anesthetic technique in molar pregnancy patients for suction curettage: A retrospective study

Anesthetic techniques for suction curettage in molar pregnancy patients described in the literature can be classed into general anesthesia and regional anesthesia techniques. The aim of the present study was to report the factors influencing the decision-making for the choice of anesthetic technique in molar pregnancy patients who underwent suction curettage at Siriraj Hospital. The reported intraoperative and postoperative complications were also analyzed.A retrospective chart review was conducted among pregnant women diagnosed with molar pregnancy who had underwent suction curettage under anesthesia at Siriraj Hospital between January 2007 to September 2021. Overall, 244 patients were diagnosed with molar pregnancy, with 110 of these included for analysis in this study after consideration of the inclusion and exclusion criteria. Quantitative data of the included patients were analyzed by either unpaired t-test or Mann–Whitney U test, while qualitative data were analyzed by the chi-square test. Logistic regression was used to establish the factors influencing the decision-making for the anesthetic technique.General anesthesia was the most preferred anesthetic technique (77.4%) in the molar pregnancy patients who had underwent suction curettage, followed by regional anesthesia (11.3%) and intravenous sedation (11.3%). General anesthesia was likely to be used in patients with an enlarged uterine size ≥ 16 weeks with an adjusted odds ratio of 11.64 (95% CI 1.08–125.72, p < 0.05). Patients with a larger uterine size were associated with higher beta-hCG levels, resulting in more severe medical complications, such as hyperthyroidism and hyperemesis gravidarum (p < 0.05). Intraoperative complications, such as uterine atony (17.7%), massive hemorrhage (7.3%), and pulmonary edema (4.2%), were confined within patients receiving general anesthesia, but there was no statistical significance. None of the patients had anesthesia-related complications. The reported postoperative serious complications, such as pulmonary edema (4.2%), which required postoperative intubation and transferal to the intensive care unit, were all in the general anesthesia group. Patients with higher co-morbidities were advised by anesthesiologists to receive general anesthesia. However, an enlarged uterine size ≥ 16 weeks was the only factor that had an influence on the decisions of the anesthesiologists to provide general anesthesia.

Perioperative pain management with regional analgesia techniques for visceral cancer surgery: A systematic review and meta-analysis

Study objectiveRegional analgesia following visceral cancer surgery might provide an advantage but evidence for best treatment options related to risk-benefit is unclear. DesignSystematic review of randomized controlled trials (RCT) with meta-analysis and GRADE assessment. SettingPostoperative pain treatment. PatientsAdult patients undergoing visceral cancer surgery. InterventionsAny kind of peripheral (PRA) or epidural analgesia (EA) with/without systemic analgesia (SA) was compared to SA with or without placebo treatment or any other regional anaesthetic techniques. MeasurementsPrimary outcome measures were postoperative acute pain intensity at rest and during activity 24 h after surgery, the number of patients with block-related adverse events and postoperative paralytic ileus. Main results59 RCTs (4345 participants) were included. EA may reduce pain intensity at rest (mean difference (MD) -1.05; 95% confidence interval (CI): −1.35 to −0.75, low certainty evidence) and during activity 24 h after surgery (MD -1.83; 95% CI: −2.34 to −1.33, very low certainty evidence). PRA likely results in little difference in pain intensity at rest (MD -0.75; 95% CI: −1.20 to −0.31, moderate certainty evidence) and pain during activity (MD -0.93; 95% CI: −1.34 to −0.53, moderate certainty evidence) 24 h after surgery compared to SA. There may be no difference in block-related adverse events (very low certainty evidence) and development of paralytic ileus (very low certainty of evidence) between EA, respectively PRA and SA. ConclusionsFollowing visceral cancer surgery EA may reduce pain intensity. In contrast, PRA had only limited effects on pain intensity at rest and during activity. However, we are uncertain regarding the effect of both techniques on block-related adverse events and paralytic ileus. Further research is required focusing on regional analgesia techniques especially following laparoscopic visceral cancer surgery.

Advantages of spinal compared to general anesthesia

Spinal anesthesia is a regional anesthesia technique achieved by a local subarachnoid anesthetic injection. Local anesthetic blocks conduct of pain on the spinal level and provides analgesia of the body below the navel. It can be used in a wide array of procedures, including laparoscopy. Inguinal hernia surgery is performed under general or regional anesthesia, depending on the indications and the individual approach of the anesthetist and surgeon. This article brings review of the literature and our experience in advantages and disadvantages of spinal anesthesia in open inguinal hernia surgery. We find that spinal anesthesia is cost effective and has advantages in inguinal hernia surgery when compared with general anesthesia, in terms of better postoperative pain control, and less nausea and vomiting, with minimal effects on hemodynamic stability.

Analgesia-nociception index accurately predicts inadequate pectoralis muscle fascia block (PECS) in patients undergoing breast surgery: A prospective observational study

BackgroundPostoperative opioid administration has been largely replaced by regional anesthesia techniques. We aimed to determine whether intraoperative Analgesia-Nociception Index (ANI) can aid in early evaluation of the effectiveness of regional blocks such as the pectoralis muscle fascia block (PECS, pectoserratus and interpectoral plane blocks) and predicting the need for analgesics postoperatively. MethodsThis prospective observational study enrolled 30 women (age: 20–80 years) undergoing unilateral, non-intubated, breast tumor excision alone or in conjunction with sentinel lymph node biopsy. PECS block was performed following sedation. ANI readings were obtained at 1-min intervals, and polar coordinates were assigned to the distance from the nipple (0.5-cm intervals) and o'clock position (15-min intervals) for each reading. Pain scores were assessed using a numeric rating scale from 0 to 10, and analgesics were administered depending on pain score post-operatively. Results8 (27%), 19 (63%), and 3 (10%) patients received morphine, tramadol, and no analgesics, respectively. In total, 954 ANI measurements were obtained. At the proposed cut-off of 50, the sensitivity and specificity of the ANI nadir for need of post-operative opioids were 0.875 and 0.932, respectively. Block effectiveness was most satisfactory in the upper lateral quadrant of the breast with nipple–areolar complex (NAC) sparing effect. Most average ANI measurements for the NAC were <50. No patient experienced postoperative nausea/vomiting, although one reported dizziness. ConclusionsThe intraoperative ANI nadir <50 was strongly correlated with need for postoperative opioids. The ANI may aid in objectively evaluating the effectiveness of pectoralis muscle fascial blocks and predicting postoperative need for analgesics.

Regional Anaesthesia Techniques for Orthopaedic Surgery at Tertiary Care Teaching Hospital

Background: Regional anaesthesia has found its uses in many aspects of orthopaedic surgery including more recently, spine surgery. Neuraxial or regional anaesthesia are often the preferred techniques for surgical anaesthesia in patients with multiple comorbidities. For instance, osteoporosis-related complications such as hip fractures are common in the growing geriatric population. Orthopaedic surgery aims to recover functional capacity in patients but it carries a specific morbidity and mortality. Orthopaedic surgery conveys several challenges for the anaesthesiologist, including prevention of thromboembolic complications, reduction of peri- and postoperative bleeding and management of autologus blood transfusion and postoperative pain. Material and Methods: This is a prospective study was conducted in the Department of orthopaedic and Anaesthesia at Shadan Institute of Medical Sciences, Teaching Hospital and Research Center. Three hundred and ten consecutive cases posted for orthopaedic surgeries were taken up for study. Anaesthesia technique was decided based on the nature of surgery, willingness and medical status of the patient and experience of the anaesthesiologists. RA was planned whenever possible. In the morning of operation the RA technique was explained to the patients and intravenous (IV) access established. Preoperative medication was given using IV fentanyl and midazolam in titrated doses. Ketamine was used in children and appropriate block given using standard technique. Nerve stimulator was used wherever applicable Results: Age of the patients ranged from three months to 92 years. Maximum number of patients belonged to the age group of 21- 50 years (63.2%). As per the demographic data. In our study, Knee arthroscopy and repair was 28.38%, Femoral was 17.41%, Radius and ulna was 15.16% and least were Ankle and foot, Wrist and hand surgery was 1.93%. In our study Subarachnoid block was 40.96% followed by Combined spinalepidural 17.09%, General anaesthesia 12.90%. Conclusion: In a conclusion, the use of regional anesthesia techniques for postoperative outcomes in orthopedic surgeries has been investigated in lots of clinical studies and case reports. Most of the authors proposed that regional anesthesia in orthopedic patients may be associated with better postoperative pain control and a reduction in intraoperative blood loss when compared with general anesthesia. In the future regional anesthesia techniques will be more preferable anesthetic technique in orthopedic surgeries

Retrolaminar block for opioid-free anaesthesia and enhanced recovery after posterior lumbar discectomy: A randomised controlled study.

Intraoperative regional analgesia and enhanced recovery are standard care models aimed at reducing perioperative opioid use following spine surgeries. This study aimed to examine the analgesic effect of retrolaminar block in promoting recovery and pain relief after posterior lumbar discectomy. The patients undergoing elective posterior lumbar discectomy were randomised into the retrolaminar group (n = 36) (received an intra-operative bilateral retrolaminar block with 15 mL of bupivacaine 0.25%, 2 mL (8 mg) of dexamethasone, and 2 mL of magnesium sulphate 10% (200 mg) on each side) and control group (n = 36) (received standard general anaesthesia). Primary outcomes were recovery time (time from isoflurane discontinuation to the first response to verbal command) and time to discharge (time from admission to the post-anaesthesia care unit (PACU) to discharge from the PACU, when Aldrete score was ≥9). P values < 0.05 were considered statistically significant. The extubation, recovery, and discharge times were significantly shorter in the retrolaminar group compared to the control group (P < 0.001). Postoperative pain scores were significantly lower in the retrolaminar group for up to 8 h compared to only 2 h in the control group (P < 0.001). The time to first administration of ketorolac post-operatively was significantly longer in the retrolaminar group compared to the control group (P < 0.001). The total consumption of ketorolac post-operatively was significantly reduced in the retrolaminar group compared to the control group (P < 0.001). Intra-operative retrolaminar block is an easy and effective opioid-free regional anaesthesia technique that improves recovery after posterior lumbar discectomy.

Spinal Anesthesia with Ultrasonography (USG) Marker in Morbidly Obese Pregnant Women Undergoing Cesarean Section Surgery: A Case Report

Background: Spinal anesthesia is a regional anesthesia technique used to provide analgesia or numbness in the lower part of the body. This technique has long been employed in childbirth and cesarean section surgeries due to its numerous advantages for pregnant women. Obese pregnant patients often have increased adipose tissue in the back area, making it challenging to identify the appropriate interspinous space.&#x0D; Case presentation: A 26-year-old primigravida at 38 weeks of gestation with morbid obesity, standing at 158 cm tall and weighing 140 kg, with a body mass index (BMI) of 56.1 kg/m², underwent cesarean section surgery under spinal anesthesia. The identification of the spinal needle insertion site was performed using pre-procedural ultrasound (USG) marker at the L3-L4 level, with heavy bupivacaine 0.5% 12.5 mg used as the anesthetic agent. The surgery lasted for 1 hour and 20 minutes, with stable hemodynamics and a blood loss of 450 ml. A female infant was delivered, weighing 3080 grams, with a length of 50 cm and an APGAR score of 8-9-10.&#x0D; Conclusion: The use of USG markers can assist in determining the precise location for spinal anesthesia injection, thereby reducing complications from repeated needle insertions.

Non-Neuraxial Chest and Abdominal Wall Regional Anesthesia for Intensive Care Physicians-A Narrative Review.

Multi-modal analgesic strategies, including regional anesthesia techniques, have been shown to contribute to a reduction in the use of opioids and associated side effects in the perioperative setting. Consequently, those so-called multi-modal approaches are recommended and have become the state of the art in perioperative medicine. In the majority of intensive care units (ICUs), however, mono-modal opioid-based analgesic strategies are still the standard of care. The evidence guiding the application of regional anesthesia in the ICU is scarce because possible complications, especially associated with neuraxial regional anesthesia techniques, are often feared in critically ill patients. However, chest and abdominal wall analgesia in particular is often insufficiently treated by opioid-based analgesic regimes. This review summarizes the available evidence and gives recommendations for peripheral regional analgesia approaches as valuable complements in the repertoire of intensive care physicians' analgesic portfolios.

Central Neuraxial Blocks as Surgical Anesthesia in Infants: A Narrative Review

: Perioperative care of neonates/infants is a great challenge for anesthesiologists, regardless of the type of anesthesia chosen. Furthermore, providing regional anesthesia techniques as “surgical anesthesia" in this population is even more difficult. In this review, the merits and demerits of all available techniques of central neuraxial blocks (CNBs) are discussed in detail, and their recent advances are discussed. The “research gaps” on this topic are also highlighted. The author hopes it would be a valuable addition to the literature and lead to further research on this potential topic.
