Peripheral nerve blocks for analgesia following cesarean delivery A narrative review.

Spinal and epidural blocks are commonly employed for pain relief during and following cesarean section. Intrathecal morphine (ITM) has been the gold standard for the same for many years. In recent times, many peripheral nerve blocks (PNBs) have been tried for postoperative analgesia following cesarean delivery (PACD). This article has reviewed the common PNBs used for PACD. The role of PNBs along with ITM has been studied and the current best strategy for PACD has also been explored. Currently, Ilio-inguinal nerve and anterior transversus abdominis plane block in conjunction with intrathecal morphine have been found to be the most effective strategy, providing lower rest pain at 6 hours as compared to ITM alone. In patients not receiving intrathecal morphine, recommended PNBs are lateral transversus abdominis plane block, single shot local anesthetic wound infiltration, or continuous wound infiltration with catheter below rectus fascia. PNBs are recommended for PACD. They have an opioid-sparing effect and are devoid of adverse effects associated with central neuraxial blocks such as hypotension, bradycardia, and urine retention. However, caution must be observed with PNBs for possible local anesthetic toxicity due to the large volumes of drug required.

Comparative evaluation of transsacrococcygeal and transcoccygeal approach of ganglion impar block for management of coccygodynia.

BACKGROUND AND AIMS: Coccygodynia or Coccydynia is pain in the area of coccyx and ganglion impar block is commonly used technique for treatment of coccygodynia. MATERIAL AND METHODS: Forty patients of either sex in the age group of 20-70 years suffering from coccygodynia, who failed to respond to six weeks of conservative treatment were enrolled in the study. All patients were subjected to detailed clinical history, examination in the Pain Management Centre (Pain Clinic) of our Institute and imaging studies were reviewed. The patients were randomly divided into two groups of 20 each by a computer generated randomization number table: Group-TS (n = 20): Patients were administered ganglion Impar block by trans-sacrococcygeal approach Group-TC (n = 20): Patients were administered ganglion Impar block by trans-coccygeal approach with 8 ml of 0.5% bupivacaine plus 2 ml of 40mg/ml methylprednisolone acetate under fluoroscopic guidance. RESULTS: Both the techniques of ganglion Impar block were effective and provided good pain relief to the patients with coccygodynia. There was a statistically and clinically significant improvement in pain score after ganglion Impar block in both the groups at all time intervals during the study period. (p < 0.05). The mean pain score after ganglion Impar block was <2 at all time intervals throughout the three month study period in all patients in the two groups. All patients in both the groups had excellent satisfaction immediately after ganglion Impar block. Five patients each in both groups required second ganglion Impar block during the three months study period. CONCLUSION: Both trans-sacrococcygeal and trans-coccygeal approaches of ganglion Impar block with a combination of local anaesthetic and steroid are safe and effective for management of coccygodynia. Trans-coccygeal ganglion Impar block through the first intra-coccygeal joint is better in terms of improvement in pain score, functional disability, patient satisfaction and ease of administration.

Achieving Surgical, Obstetric, Trauma, and Anesthesia (SOTA) care for all in South Asia.

South Asia is a demographically crucial, economically aspiring, and socio-culturally diverse region in the world. The region contributes to a large burden of surgically-treatable disease conditions. A large number of people in South Asia cannot access safe and affordable surgical, obstetric, trauma, and anesthesia (SOTA) care when in need. Yet, attention to the region in Global Surgery and Global Health is limited. Here, we assess the status of SOTA care in South Asia. We summarize the evidence on SOTA care indicators and planning. Region-wide, as well as country-specific challenges are highlighted. We also discuss potential directions-initiatives and innovations-toward addressing these challenges. Local partnerships, sustained research and advocacy efforts, and politics can be aligned with evidence-based policymaking and health planning to achieve equitable SOTA care access in the South Asian region under the South Asian Association for Regional Cooperation (SAARC).

Comparative Evaluation of Intraarticular Facet Joint Injection Versus Medial Branch Block in Patients With Low Back Pain: A Randomised Controlled Study.

INTRODUCTION: Lumbar facet joint pain may refer to the back, buttocks, and proximal parts of the lower extremities. Intraarticular facet joint injections, facet joint nerve blocks, or facet joint neurolytic procedures are popular for the management of facet joint pain. MATERIAL AND METHODS: In this prospective, randomised study, 60 patients with a medical evaluation and pain pattern consistent with lumbar facet joint pain were randomly allocated to two groups. Group Ⅰ (n=30) patients were administered fluoroscope-guided lumbar facet joint injection, and group Ⅱ (n=30) patients were administered fluoroscope-guided lumbar facet joint nerve block. The primary objective is to compare the efficacy of both in managing facet joint pain in terms of pain and disability improvement. Secondary objectives were to compare the requirement for repeat injections and parameters related to the block, such as ease of administering the block, and to note the side effects pertaining to either of the blocks. RESULTS: There was a statistically significant improvement in pain score after injection in both groups (p>0.05). The mean pain score in both groups remained less than two at all time intervals throughout the study period (p>0.05) Excellent patient satisfaction was reported by the majority of the patients at different time intervals in both groups. CONCLUSION: Both lumbar facet joint injection and lumbar facet joint nerve block are safe and effective techniques for managing lower back pain patients. Both techniques provide adequate pain relief and disability improvement.

Recent trends in chronic pain medicine.

Chronic pain presents as an unequalled challenge for physicians, owing to the complexity of biochemical and biological pathways involved in pain transmission and high variability of pain perception among individuals. Often, there is an inadequate response to conservative treatment, and opioid treatment has its own drawbacks, such as side effects and opioid dependence. Hence, novel strategies have evolved for the effective and safe management of chronic pain. Radiofrequency technique, regenerative biomaterial, platelet-rich plasma, mesenchymal stem cells, reactive oxygen species scavenger nanomaterial, ultrasound-guided interventional pain management procedures, endoscopic spinal procedures, vertebral augmentation therapy, and neuromodulation are some of the promising and upcoming modalities in the armamentarium of pain physicians.

Comparative evaluation of midline versus parasagittal interlaminar epidural steroid injection for management of symptomatic lumbar intervertebral disc herniation.

Background and Aims: Epidural steroid injections (ESIs) with or without local anaesthetics have been used for the past several years for the treatment of back pain, especially for radicular symptoms. The aim of this prospective study was to compare the efficacy of midline with parasagittal approach for interlaminar ESI in the management of symptomatic lumbar intervertebral disc herniation. Methods: Sixty patients (aged 20-60 years) with pain pattern consistent with lumbar radiculopathy caused by lumbar intervertebral disc herniation and who did not respond to conservative treatment were included in the study. They were randomly divided in two groups of 30 each: group I (MILESI, n = 30) consisting of midline interlaminar ESI, and group II (PSILESI, n = 30) consisting of parasagittal interlaminar ESI. They were administered a combination of 80 mg of methylprednisolone acetate (40 mg/ml) and 6 ml of 0.25% bupivacaine (total volume of 8 ml). Pain, patient satisfaction, and the Oswestry Disability Index (ODI) were assessed at different time intervals before and after the procedure for up to six months. Results: The improvement in pain score after ESI was statistically significant in both the groups at all intervals of time, with no significant difference between the two groups. The mean pain score was <3 from two weeks onwards after the injection. The pain score decreased by more than five points and it was around two points at the end of the six-month study period. Around 50% of patients in both groups had excellent satisfaction. Conclusion: Both techniques were effective in providing good analgesia. Pain relief and improvement in disability were clinically better with the parasagittal interlaminar approach.

Breaking barriers to remain healthy and fit during a residency in anaesthesiology.

Anaesthesiology is a high-demand speciality of medicine in terms of long and unpredictable work hours, stressful work requirements, pressure for a cent per cent productivity in academics, clinical work and research.

In the journey as a trainee anaesthetist, vigorous and diligent efforts are needed to gain perfection in knowledge and skills ultimately. While this path is being transversed, it is essential to address physical and mental fitness by exercising it to the recommended benefits, to ward away stress and burnout. In this special article, the authors will discuss the barriers young anaesthesia trainees face to staying healthy and fit during their training and practical and appropriate measures to mitigate the same through intervention at various levels of hierarchy.

Postgraduate examination: How to match your presentation skills with examiner's expectations?

Passing the exit Doctor of Medicine/Diplomate of National Board examination is a significant but challenging milestone in the career of any student. A strong knowledge base is the foundation on which a student can build an impactful performance. Knowledge core is tested in the theory part of the examination and its application to patient care during case presentations and viva in the practical examination. Performance during the practicals has one common denominator: convincing the examiner that the patient during anaesthesia would be safe in the student's hands. The way the student answers, the spontaneity and the confidence that the student exudes in answering, the pointed answers to the questions asked, and setting the priorities right when dealing with a multitude of tasks at hand go a long way in ensuring that. This article describes what examiners expect from students and provides tips to postgraduate students preparing for the examination.

The changing face of postgraduate anaesthesia teaching curriculum: Need of the hour!

The speciality of anaesthesiology is evolving rapidly. The recent pandemic witnessed anaesthesiologists as the front-liners catering not only as critical care physicians but also as trainers and even administrators. Today, anaesthesiologists are required to have not just sound clinical knowledge but also proficiency in skills and techniques and aptitude for leadership. The recently introduced competency-based postgraduate training programme for anaesthesiology in India with its specific learning objectives envisages the creation of competent specialists with a broad range of skills who are competent not only to handle effectively medical problems but also acquire the basic teaching skills, communication skills and leadership qualities. The curriculum marks a paradigm shift from university-based, passive, teacher-centric to student-centric, active teaching-learning methods including problem-based and self-directed learning. The mindset, lack of adequately trained faculty, infrastructure, learning resources and time constraints form the major impediment in the successful implementation of the new curriculum.

Pain medicine as a career.

Pain is one of the most common causes of seeking medical care. In the day to day clinical practice, incidence of pain of some origin is next only to common cold. The average life span of an Indian has also increased and this population is vulnerable to chronic and cancer pain. Anaesthesiologists are well-versed with the art and science of treating pain and their role as pain physician is a natural extension of the professional work. 'Pain Medicine' is growing as a speciality. Last two decades have seen an explosive growth in the scientific study of pain and anaesthesiologists taking up pain medicine as a career. Postgraduate students can certainly adopt this super speciality. This article highlights the merits and depicts various aspects of 'pain medicine' as a career.

Regional anaesthesia practices in India: A nationwide survey.

BACKGROUND AND AIMS: There are no surveys documenting the existing regional anaesthesia (RA) practices in our country. This nationwide survey aims to record the existing RA practices, identify any lacunae that might exist and project the future direction of evolution. METHODS: This online survey consisting of 31 questions was sent to all members of the Indian Society of Anaesthesiologists and addressed participants' demographic features, central neuraxial block and peripheral nerve block practices, drug selection, RA training and safety measures. The data were analysed using Statistical Package for the Social Sciences version 24.0. All categorical variables were expressed as frequencies and percentages. RESULTS: A total of 2141 responses were received, with participants distributed across the country. Forty-two per cent of the respondents reported that more than 60% of surgeries were performed under RA. Most of the participants use 'traditional' test dose for epidural space confirmation. Fifty participants (2.4%) use ultrasound for neuraxial space identification. Twenty per cent of the participants use a checklist for monitoring post-operative epidural analgesia. 6.7% have undergone specialised training in RA. Around 3.5% of the respondents have performed a wrong-side block. 31.4% of the respondents store intralipid in the operating room. CONCLUSION: The current survey highlights the prevailing practices, various deficiencies in monitoring and the need for RA training programmes. The data accrued can serve as a baseline for future comparison.

Telemedicine for chronic pain management during COVID-19 pandemic.

Treatment of chronic pain is an essential service. Due to lockdown, travel restrictions, social and physical distancing requirements or fear that health care facilities may be infected; patients may avoid visiting health care facilities in person. It is also imperative to decrease the risk of exposure of the health care workers (HCWs) to severe acute respiratory syndrome corona virus 2 (SARS CoV2) and to ease the overtly burdened health care system. But any disruption in pain practice will have alarming consequences for individuals, society, and whole of health care system and providers. In the current scenario of COVID-19 pandemic, telemedicine is emerging as a key technology for efficient communication and sustainable solution to provide essential health care services and should be considered for chronic pain patients (CPPs). Recently, Board of Governors in supersession of Medical Council of India along with National Institution for Transforming India (NITI Aayog) released "Telemedicine Practice Guidelines" enabling registered medical practitioners to provide healthcare using telemedicine. This article describes the challenges in CPPs during COVID-19 pandemic and the use of telemedicine as the rescue management vehicle for CPPs in current scenario.

Tough times and Miles to go before we sleep- Corona warriors.

The world has changed due to COVID-19 pandemic. Global spread of COVID-19 has overwhelmed all health systems and has incurred widespread social and economic disruption. The authorities are struggling to ramp up the healthcare systems to overcome it. Anaesthesiologists are facing long duty hours, have fear of bringing disease home to their families, being companion to critically ill patients on long term life support, being on front line of this pandemic crisis, may take toll on all aspects of health of corona warriors- physical, mental, social as well as the emotional.At this juncture, we must pause and ask this question to ourselves, "Buried under stress, are we okay?"

Indian Resuscitation Council (IRC) suggested guidelines for Comprehensive Cardiopulmonary Life Support (CCLS) for suspected or confirmed coronavirus disease (COVID-19) patient.

Management of the recent outbreak of the novel coronavirus disease (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) remains challenging. The challenges are not only limited to its preventive strategies, but also extend to curative treatment, and are amplified during the management of critically ill patients with COVID-19. Older persons with comorbidities like diabetes mellitus, cardiac diseases, hepatic impairment, renal disorders and respiratory pathologies or immune impairing conditions are more vulnerable and have a higher mortality from COVID-19. Earlier, the Indian Resuscitation Council (IRC) had proposed the Comprehensive Cardiopulmonary Life Support (CCLS) for management of cardiac arrest victims in the hospital setting. However, in patients with COVID-19, the guidelines need to be modified,due to various concerns like differing etiology of cardiac arrest, virulence of the virus, risk of its transmission to rescuers, and the need to avoid or minimize aerosolization from the patient due to various interventions. There is limited evidence in these patients, as the SARS-CoV-2 is a novel infection and not much literature is available with high-level evidence related to CPR in patients of COVID-19. These suggested guidelines are a continuum of CCLS guidelines by IRC with an emphasis on the various challenges and concerns being faced during the resuscitative management of COVID-19 patients with cardiopulmonary arrest.

Comparison of efficacy of ketamine versus thiopentone-assisted modified electroconvulsive therapy in major depression.

BACKGROUND: It is well known that depression improves faster with electroconvulsive treatment (ECT) than with antidepressant medications. N-methyl-D-aspartate-receptor antagonists (ketamine) have been shown to have rapid antidepressant effects when given as an intravenous infusion. Faster recovery with ECT is likely when used with ketamine as anesthetic. AIM: The aim of the study is to compare the outcome of modified electroconvulsive therapy (MECT) in major depressive disorder patients undergoing MECT with ketamine versus thiopentone anesthesia. MATERIALS AND METHODS: Sixty hospitalized patients (age: 18-45 years) with major depressive disorder (Diagnostic and Statistical Manual of Mental Disorders-IV Text Revision) were randomly allocated to either of the two MECT groups (30 patients each) receiving ketamine or thiopentone as anesthetic agent. The participants were assessed on a weekly basis on Hamilton Rating Scale for Depression (HAM-D) and Beck Depression Inventory (BDI). RESULTS: Ketamine group required significantly lesser number of MECT sessions for achieving remission and had rapid improvement in HAM-D and BDI scores compared to the thiopentone group. Furthermore, the stimulus intensity required to elicit seizures was significantly less and seizure duration was longer in ketamine group compared to the thiopentone group. CONCLUSION: The use of ketamine for anesthesia led to rapid recovery from depressive symptoms and seems to be a better option for depressive patients, especially when a rapid response is desired.
