Anesthetic Considerations in Multisystem Inflammatory Syndrome in Children: A Case Series

Multisystem inflammatory syndrome in children (MIS-C) is an immune response inciting multiorgan dysfunction and a shock-like state which is typically seen in children 2 to 6 weeks after either a coronavirus disease-19 infection or exposure. When such a child comes for any surgery, perioperative anesthetic management demands multidisciplinary involvement and individualized case-based decision-making. Due to the novelty of the condition, there are limited data on anesthetic implications in these patients. Anesthetic management in the affected children is dynamic depending on the organ systems involved and the progression of the disease state. Though the long-term effects of the syndrome are largely unknown, we hope that awareness of the MIS-C-associated complications may help anesthesiologists involved in childcare. Herein, we put forward challenges and clinical dilemmas we faced during the anesthetic management of three children with MIS-C presenting for emergency and elective surgery.

Ultrasound-Guided Superficial Radial Nerve Block in the Emergency Department for Pain Management following Centipede Bite

Centipede bites are reported in many parts of tropical and subtropical countries, such as India. Centipede envenomation produces significant local symptoms, with pain being the most prominent symptom. The emergency department (ED) plays a crucial role in managing the victims through appropriate pain management and control of other local and systemic symptoms. Nonopioids and weak opioids, along with local measures, are often employed, but the intense pain is often refractory to these conventional techniques. Regional anesthesia has numerous benefits over these traditional measures, such as avoidance of polypharmacy and its consequent systemic adverse effects, excellent quality of pain control, and decreased need or avoidance of hospital admission. The applications of regional anesthesia have recently increased tremendously in the ED but are unreported for the management related to centipede bites. We report a case of centipede bite in which conventional analgesics did not help, and the pain was successfully managed by low-volume selective sensory peripheral nerve block.

Caffeine - Essentials for anaesthesiologists: A narrative review

Caffeine has a multitude of uses in anaesthesia, and numerous studies have evaluated its efficacy and usefulness in various aspects of anaesthesia and medical practice. Its various applications in anaesthesia include its role in awakening from anaesthesia, managing post-dural puncture headache, managing post-sedation paradoxical hyper-activity in children, post-operative bowel paralysis, and apnoea in paediatric populations, that is, apnoea in infancy, paediatric obstructive apnoea, and post-anaesthetic apnoea in pre-mature infants. Though the effects of caffeine on bronchial smooth muscle, neurological, and cardio-vascular systems are well known, the relatively little-known effects on the endocrine and gastro-intestinal (GI) system have been recently taking primacy for eliciting its therapeutic benefits. The literature shows encouraging evidence in favour of caffeine, but unambiguous evidence of caffeine benefits for patients is lacking and needs further investigation. In this narrative review of literature, we summarise the available literature to provide insights into the pharmacokinetics, pharmacodynamics, clinical application of caffeine in modern anaesthetic practice, and evidence available in this field to date. An awareness of the various physiological effects, adverse effects, reported applications, and their evidence will widen the horizon for anaesthesiologists to increase its rational use and advance research in this field. Well-designed randomised controlled trials regarding the various outcomes related to caffeine use in anaesthesia should be planned to generate sound evidence and formulate recommendations to guide clinicians.

Sacral ESP for pain management in transforaminal lumbar interbody fusion cases: A case series

Lumbar erector spinae plane block (ESPB) is effective for spine surgeries but is deep and technically demanding. Sacral ESPB is a novel approach for sacrococcygeal procedures and can potentially cover lumbar dermatomes by the cranial drug spread. This is the first reported case series demonstrating the potential analgesic efficacy of sacral ESPB for lumbar spine surgeries. Five patients with radiculopathy at the lumbosacral area level were scheduled for transforaminal lumbar interbody fusion (TLIF). General anaesthesia was induced as per standard practice. All patients received sacral ESP in a prone position under ultrasound guidance with a needle inserted in-plane while targeting the fascial plane between the S2 median crest and overlying muscles. All the included patients had good analgesia in the postoperative period and required minimal opioid analgesic doses. Sacral ESPB is an easy, effective, and safe technique in the scheme of multimodal analgesia for TLIF surgeries as a component of pre-emptive analgesia, where the main goal is an opioid-sparing effect.

Analgesic efficacy of Clonidine as an adjuvant in ultrasound-guided rectus sheath block for midline incisional hernia repair - A randomized double-blind controlled trial

Background and Aims

Clonidine as an adjuvant has not been evaluated in rectus sheath block (RSB) for postoperative pain management in incisional hernia repair. The study aims to evaluate clonidine as an adjuvant in single-shot RSB along with general anesthesia (GA).

Material and Methods

This randomized, double-blind controlled study was conducted following IEC-Human approval and written informed consent from 30 patients of either sex, aged 16 to 60 years, ASA physical status I or II undergoing midline incisional hernia repair under GA. All patients received ultrasound-guided bilateral RSB following administration of GA. The subjects enrolled in the study were randomly allocated to receive either normal saline 1 mL (group B) or clonidine 1 μg/kg diluted to 1 mL with normal saline (group BC) as adjuvant along with 9 mL bupivacaine hydrochloride 0.25%. Inj. tramadol 1 mg/kg was administered for rescue analgesia. The primary outcome was the time to first request for analgesia, and secondary outcomes were total consumption of rescue analgesic over 24 h, numerical rating score (NRS), patients' satisfaction, hemodynamics, and side effects. Unpaired t-test and Chi-square test were used.

Results

On intergroup analysis, the mean time to first request for analgesia (in min) was significantly higher in group BC i.e., [9.60 (± 5.23) vs 5.33 (± 3.53); (P < 0.034]; whereas, the mean rescue analgesic consumption in 24 h (in mg) was higher in group B i.e., [(88.00 ± 60.97) vs (46.00 ± 48.08)]; (P < 0.045)]. Hemodynamic parameters i.e., mean blood pressure and heart rate were comparable between the two groups, and there were no side effects.

Conclusion

Clonidine as an adjuvant in single-shot ultasonography (USG)-guided RSB along with GA is efficacious for postoperative pain management following midline incisional hernia repair.

Gastrointestinal endoscopy procedures under intravenous sedation in the prone position: keep LMA gastro handy!

Gastrointestinal endoscopies are often done in the prone position and anesthesiologists are needed to provide sedation. Airway access is limited in the prone position and may make timely airway management difficult in case of airway obstruction during sedation. Specialized laryngeal mask airway devices customized for endoscopy procedures like LMA® Gastro™ can be inserted in the prone position and may help anesthesiologists tide over such crisis situations while simultaneously allowing the endoscopy procedures through the dedicated conduit available for inserting the endoscopes. We have described one such case managed successfully by inserting LMA® Gastro™ in the prone position.

COVID-19 associated Mucormycosis (CAM): Implications for perioperative physicians - A narrative review

Mucormycosis once considered a rare disease with an incidence of 0.005 to 1.7 per million, has become one of the greatest menaces during the coronavirus disease (COVID-19) pandemic. India alone has contributed to nearly 70% of the global caseload of COVID-associated mucormycosis (CAM) and it had even been declared as a notifiable disease. Second wave of COVID-19 pandemic saw a steep rise in the incidence of mucormycosis and these patients have been presenting to anesthesiologists for various surgical procedures due to its primary or secondary sequelae. Rhino-orbito-cerebral mucormycosis (ROCM) is the commonest manifestation and is caused by Rhizopus arrhizus. Injudicious use of corticosteroids in vulnerable patients could have been a major contributing factor to the sudden rise in ROCM during the pandemic. Concerns related to anesthetic management include COVID-19 infection and post COVID sequalae, common presence of uncontrolled diabetes mellitus, possibility of difficult mask-ventilation and/or intubation, various drug therapy-associated adverse effects, and interaction of these drugs with anesthetic agents. Thorough preoperative optimization, multidisciplinary involvement, perioperative care, and vigilance go a long way in improving overall outcomes in these patients.

Unilateral sacral erector spinae plane block for lower limb surgery in children

The erector spinae plane block is a versatile regional anaesthesia technique used for a variety of truncal surgeries. A novel variation is the sacral erector spinae plane block which is gaining popularity for perineal and anorectal procedures. Local anaesthetic injected at this level blocks the sacral dermatomes and has the potential for more proximal spread to involve lumbar nerve fibres via spread to the lumbar plexus or the epidural space. The advantage of a sacral erector spinae plane block over a neuraxial block is that it is less invasive and may have a better safety profile: there is a reduced risk of epidural haematoma, epidural abscess, haemodynamic instability and motor weakness of the lower extremities. Until now, this approach has been used for midline surgical procedures when the local anaesthetic was injected bilaterally. Its application for lower limb procedures with a single unilateral injection has not been described. We report the use of a unilateral sacral erector spinae plane block at the level of the S2 median crest in two children undergoing lower limb procedures of the hip and thigh. The block was found to provide effective peri-operative analgesia with minimal need for any opioid analgesics and without any significant adverse effects.

Comparative evaluation of King Vision videolaryngoscope channeled and non-channeled blades with direct laryngoscope for intubation performance and skill retention by medical students: a randomized cross over two period study

PURPOSE

A videolaryngoscope(VL) with an intubation conduit like KingVision channeled(KVC) blade may provide an added advantage over a non-channeled VL like a KingVision non-channeled (KVNC) blade and direct laryngoscope (DL) for acquiring and retention of intubation skills, especially in novices.

METHODS

In this prospective two-period randomized crossover trial, one hundred medical students used three laryngoscopes KVC, KVNC and DL for intubation following standardized training with the study devices using a Laerdal Airway Management Trainer. After one month, all participants attempted intubation, in the same manner, using all devices. The duration of intubation, modified Cormack-Lehane (CL) grade, percentage of glottic opening (POGO) score, first-attempt success, number of attempts, ease of intubation and dental trauma was recorded. The retention of intubation skills after 1 month was also assessed on the same parameters.

RESULTS

Median intubation times of KVC and DL were comparable and significantly better than KVNC (P < 0.001). The median POGO score was better with both videolaryngoscopes when compared with DL. The ease of intubation (P < 0.0012) and first-attempt success rate (P = 0.001) at the time '0' was significantly better with KVC compared to KVNC and DL. KVC fared better with respect to these intubation parameters during intubation after one month as well.

CONCLUSION

KVC performed better in terms of time to intubation, success rate and ease of procedure as compared to KVNC and DL, both for acquisition and retention of skill. Hence, we advocate that KVC should be the preferred device over KVNC and DL for teaching intubation skills to novices.

Rationale for integration of palliative care in the medical intensive care: A narrative literature review

Despite the remarkable technological advancement in the arena of critical care expertise, the mortality of critically ill patients remains high. When the organ functions deteriorate, goals of care are not fulfilled and life-sustaining treatment becomes a burden on the patient and caregivers, then it is the responsibility of the physician to provide a dignified end to life, control the symptoms of the patient and provide psychological support to the family members. Palliative care is the best way forward for these patients. It is a multidimensional specialty which emphasizes patient and family-based care and aims to improve the quality of life of patients and their caregivers. Although intensive care and palliative care may seem to be at two opposite ends of the spectrum, it is necessary to amalgamate the postulates of palliative care in intensive care units to provide holistic care and best benefit patients admitted to intensive care units. This review aims to highlight the need for an alliance of palliative care with intensive care in the present era, the barriers to it, and models proposed for their integration and various ethical issues.

Upper Thoracic Erector Spinae Plane Block-A Win-Win Deal For Polytrauma Victims Undergoing Surgeries in the Shoulder Region: A Case Report

Polytrauma victims are usually in severe pain with difficulty in breathing. There are limited regional analgesia options that cover the shoulder region as well as the rib and other associated fractures. The erector spinae plane block (ESPB) is a versatile block which has established a role in the management of rib fracture pain and has emerging indications for managing pain in the shoulder and upper humerus regions. We examined the efficacy of ultrasound guided ESPB at the T2 level in two polytrauma patients with unilateral scapular, humerus, and rib fractures undergoing surgery in the shoulder region. It provided excellent postoperative analgesia and helped to alleviate pain of associated rib and other fractures, thereby facilitating early postoperative recovery and rehabilitation.

Comparison of C-MAC and McGrathMAC Videolaryngoscopes for Intubation in Patients with Normal Airway by Donned Anaesthesiologists Using an Intubation Box During COVID-19 Pandemic: A Prospective, Randomized Study

Objective:

Intubation is a highly aerosol-generating procedure. Recent airway management guidelines advocate the use of appropriate personal protective equipment, videolaryngoscope, and “intubation box” while intubating a suspected or infected coronavirus patient. We undertook a study to compare C-MAC videolaryngoscope with McGrath videolaryngoscope for tracheal intubation using an intubation box by donned anaesthesiologists.

Methods:

The patients were randomly allocated to 2 groups by computer-generated random numbers, depending upon the videolaryngoscope used. In group C, C-MAC videolaryngoscope (n = 30) was used, whereas McGrath videolaryngoscope was used in group M (n = 30). The primary outcome was the total time required for successful intubation. The secondary outcomes included the number of attempts required, Cormack and Lehane grade, the percentage of glottis opening score, the difficulty faced while using the device, and the user’s preference.

Results:

The time to intubation was 57.17 ± 19.98 seconds with C-MAC videolaryngoscope as compared to 57.93 ± 14.92 seconds with McGrath. Both the devices had a good percentage of glottis opening score. Twelve patients in each group were found to have a Cormack and Lehane grade of 1. The time to glottis visualization was more with McGrath than with C-MAC although not significant (23.8 ± 14.03 vs 20.10 ± 10.78 seconds). Both the devices were easy to use.

Conclusions:

Both C-MAC and McGrath videolaryngoscopes are equally effective devices for intubation by a donned anaesthesiologist using an intubation box. McGrath with a disposable blade should be preferred for intubation in these conditions.

Effect of Intravenous Calcium Gluconate on Prevention of Post Spinal Hypotension during Spinal Anaesthesia for Caesarean Section: A Randomized Double-Blind Controlled Study

BACKGROUND

Calcium, a physiological ion, causes vasoconstriction and has a positive ionotropic action on heart. Its use to prevent post-spinal hypotension has been suggested but never formally evaluated for patients undergoing caesarean section. This study investigated the hemodynamic effects of calcium administration in parturients with the primary aim of comparing the incidence of post-spinal hypotension.

METHODS

Sixty healthy full-term pregnant patients scheduled for caesarean section were randomly allocated to two equal groups to receive either calcium gluconate or normal Saline bolus over 20min by syringe infusion pump under electrocardiography monitoring immediately after the patient was turned supine following spinal anaesthesia. Blood pressure and heart rate were recorded at baseline, and at regular intervals following spinal. Maternal calcium levels were estimated before and after infusion. Neonatal blood gas analysis and calcium level were analyzed. Total mephentermine requirement was recorded in both groups.

RESULTS

The heart rate values remained comparable to baseline value in group calcium gluconate while in group normal Saline, it decreased significantly at 8,12 and 16min. Blood pressure decreased significantly as compared to the baseline value from 4min onwards in both the groups. However, it was comparable in the two groups at all time points(0.622). Nineteen patients(63.33%) required mephentermine infusion in group calcium gluconate as compared to 23 patients(76.6%) in group normal Saline for maintenance of systolic blood pressure.(p=0.791) Umbilical venous pH (p=0.038) and partial pressure of carbon dioxide(p=0.038) were significantly better in group calcium gluconate.

CONCLUSIONS

Calcium used for prophylaxis of hypotension in healthy parturients undergoing caesarean section reduced the vasopressor requirements and total mephenteramine dose, but the difference did not attain statistical significance.

Acute upper gastrointestinal bleeding: A stitch on time saves nine

Upper gastrointestinal bleeding is common and often needs timely intervention for optimal outcomes. Esophageal bleeding may occur due to local advancement of malignancy or bleeding from an arterio-oesophageal fistula. We discuss the management options available for such cases.
