Recent advances in cardiac anaesthesia.

The speciality of cardiac anaesthesia has rapidly evolved over the past few decades with advances in technology, including artificial intelligence (AI), newer devices, techniques, imaging, pain relief and a better understanding of the pathophysiology of disease states. Incorporation of the same has led to improved patient outcomes in terms of morbidity and mortality benefits. With the advent of minimally invasive surgical methods, minimising the dose of opioids and ultrasound-guided regional anaesthesia for pain relief, enhanced recovery after cardiac surgery has been made possible. Perioperative imaging including 3D transoesophageal echocardiography, newer devices and drugs and AI algorithms will play a significant role in cardiac anaesthesia. This review briefly addresses some of the recent advances that the authors believe can impact the practice of cardiac anaesthesia.

Comparison of ultrasonographic anatomy of spine in traditional sitting position versus crossed leg position in term pregnancy: A prospective, observational, crossover study.

Background and Aims: The traditional sitting position (TSP) and crossed leg sitting position (CLSP) are positions used for neuraxial anaesthesia. This study compared the interspinous space (ISS) distance using ultrasound assessment of the spine in these positions in parturients in term gestation. Methods: This prospective, observational study involved ultrasonographic spine assessment in 100 parturients in term gestation with them in either TSP or CLSP. The median sagittal view measured the crescent-shaped hyperechoic reflections of the spinous processes and ISSs in L3-L4, L4-L5 and L5-S1 levels. The paramedian sagittal oblique view showed interlaminar spaces (ILSs). Paired t-test and Chi-square test were used for continuous and categorical variables, respectively. Results: The ISS distance (cm) increased in CLSP compared to TSP at levels L3-L4 (1.44 [0.34] [1.34-1.54] versus 1.22 [0.30] [1.12-1.32], P = 0.04), L4-L5 (1.34 [0.39] [1.20-1.48] versus 1.14 [0.30] [0.96-1.32], P = 0.01) and L5-S1 (1.28 [0.33] [1.17-1.39] versus 1.18 [0.23] [1.11-1.26], P = 0.02). The ILS distance (cm) increased in CLSP compared to TSP at interspaces L3-L4 (1.27 [0.34] [1.18-1.36] versus 1.12 [0.20] [1.08-1.16], P = 0.001), L4-L5 (1.26 [0.33] [1.17-1.35] versus 1.19 [0.32] [1.12-1.26], P = 0.01) and L5-S1 (1.28 [0.33] [1.18-1.38] versus 1.16 [0.27] [1.09-1.23], P = 0.001). Conclusion: Crossed leg sitting position for neuraxial anaesthesia in term pregnancy results in more widening of both interspinous and interlaminar spaces compared to traditional sitting position.

An Observational Crossover Study of N95 Respirator with Surgical Mask and Visor in Various Combinations on Healthy Volunteers and Their Impact on Physiological Variables.

Background and Aim: The COVID pandemic necessitated the use of masks to reduce the propagation of coronavirus by airborne transmission. This research was conducted in healthy volunteers to assess the changes in noninvasive measurable physiological variables over 45 min at rest. Methods: This was a prospective randomized controlled crossover trial. Twenty-one healthy volunteers were monitored for pulse rate (PR), peripheral oxygen saturation (SpO2), systolic blood pressure (SBP), diastolic blood pressure (DBP), respiratory rate (RR), inspired carbon dioxide and expired carbon dioxide (ECO2), inspired (FiO2) and expired oxygen (FeO2), every 15 min for 45 minute (min) with N95 respirator, N95 respirator with surgical mask (SM), N95 with SM and visor (V), SM with N95, and N95 respirator with visor. Results: Repeated measures analysis of variance (ANOVA) of PR, RR, SpO2, SBP, and DBP over time within the group and intragroup was calculated and found statistically insignificant. P value for comparison of mean value within the group was calculated by paired t-test with Bonferroni correction. There was a significant rise in ECO2 in the N95 group over time, and repeated measures ANOVA showed P = 0.04 at 30 min between the N95 + V group and the N95 + SM + V group. Inspired CO2 was statistically significant over time in the N95 + SM + V with P = 0.02. Conclusion: N95 alone or in combination with a SM and visor does not cause any clinically significant measurable physiological derangements. The inspired CO2 may be implicated in the symptoms manifested by individuals.

Cross clamping of the supraceliac aorta is effective for bleeding control in ruptured giant splenic artery pseudoaneurysm when proximal and distal control of the splenic artery is not possible: a case report.

Splenic artery pseudoaneurysm is the most common of all the visceral artery pseudoaneurysms. Presentation is often variable and the condition demands immediate diagnosis and management because pseudoaneurysm rupture increases morbidity and mortality. It is associated with pancreatitis and other conditions like abdominal trauma, chronic pancreatitis, pseudocyst of the pancreas, liver transplantation, and, rarely, peptic ulcer disease. We present a case of a giant splenic artery pseudoaneurysm measuring 14x8 cm. Proximal and distal control of the vessels could not be achieved during the procedure because of local adhesions and inflammation and it was necessary to cross clamp the supraceliac aorta to control bleeding.

O pseudoaneurisma de artéria esplênica é o mais comum entre os pseudoaneurismas de artérias viscerais. A apresentação geralmente varia e requer diagnóstico e tratamento imediatos, pois a ruptura do pseudoaneurisma aumenta a morbimortalidade. Esse tipo de pseudoaneurisma está associado à pancreatite e a outras condições, como trauma abdominal, pancreatite crônica, pseudocisto de pâncreas, transplante de fígado e, raramente, úlcera péptica. Apresentamos um caso de pseudoaneurisma gigante de artéria esplênica, com tamanho de 14x8 cm. Durante o procedimento, não foi possível alcançar controle proximal e distal dos vasos devido a aderências locais e inflamação, sendo necessário o clampeamento da aorta supracelíaca para controle do sangramento.

Comparison of the influence of low dose etomidate and propofol as priming dose on the incidence of etomidate induced myoclonus: a randomised, double-blind clinical trial.

BACKGROUND: Though hemodynamically stable, etomidate is known for its myoclonus side effect following induction. The main aim of this study is an effective attempt to decrease the incidence of myoclonus with a priming agent. METHODS: A prospective, double-blind study was carried out on 50 adults posted for elective surgery. After premedication, priming was done with etomidate 0.03 mg.kg-1 (Group E) and propofol 0.2 mg.kg-1 (Group P), i.e., 1/10th of induction dose. After 60 seconds of priming, patients were induced with etomidate by titrating dose over 60 seconds until loss of verbal command and eyelash reflex. The grading of myoclonus, induction dosage, and hemodynamics for 10 minutes post induction were recorded. RESULTS: In the study, only 4 cases had myoclonus. Grade 1 myoclonus was encountered in three cases of etomidate group, while only one case in the propofol group had grade 2 myoclonus which was not statistically significant (p-value: 0.12). There was a significant reduction in the etomidate induction dosage in both groups. CONCLUSION: Priming with etomidate and propofol is equally effective in reducing myoclonus with the added benefit of hemodynamic stability and reduction of an induction dose of etomidate (> 50%).

Comparison of Postoperative Pain and Analgesia Requirement among Diabetic and Nondiabetic Patients undergoing Lower Limb Fracture Surgery - A Prospective Observational Study.

Background: Diabetic patients usually experience neuropathic pain and have a decreased response to opioids. Fractures are acute conditions and as such, they are very painful. No data is available related to fracture and postoperative pain in diabetics. Aim: This study was conducted to evaluate postoperative pain and analgesics requirement among diabetic and nondiabetic patients undergoing lower limb fracture surgery and the effect of glycosylated hemoglobin (HbA1c) on the postoperative pain. Setting and Design: This was a prospective observational study, conducted on 80 patients comprising of nondiabetic and diabetic, scheduled for elective lower limb fracture surgery under spinal anesthesia. Materials and Methods: HbA1c was done in all the patients who were included in the study. Postoperative Visual Analog Scale (VAS) and analgesic consumption were assessed by an anesthesiologist blinded to the diabetic or nondiabetic status of the patients. VAS was assessed every 2nd hourly, for 24 h and rescue analgesia was given if the VAS was ≥4 and record was maintained. Sedation scores and adverse effects were also recorded postoperatively. Statistical Analysis: The Chi-square test was used for the analysis of categorical variables and Student's t-test was used for continuous variables. Results: Diabetic group of patients had a significantly high VAS score with P ≤ 0.05. Rescue analgesics requirement was significantly different in two groups with diabetic patients requiring more supplementation of analgesia with a P = 0.025. The overall patient satisfaction was lesser in diabetic group (P = 0.004). There was statistically significant correlation between glycosylated hemoglobin and VAS at 2nd, 16th, 18th, 20th, 22nd, and 24th h. Conclusion: Postoperative pain and analgesic requirement was significantly higher in diabetic patients with lower limb fracture. Glycosylated hemoglobin had good correlation with higher VAS.

Sphenopalatine ganglion block: Intranasal transmucosal approach for anterior scalp blockade - A prospective randomized comparative study.

BACKGROUND AND AIMS: Peripheral nerve blocks in neurosurgical practice attenuate most stressful responses like pin insertion, skin, and dural incision. Scalp block is conventionally the blockade of choice. Further studies for less invasive techniques are required. Intranasal transmucosal block of the sphenopalatine ganglion has shown promising results in patients with chronic headache and facial pain. The primary objective of our study was to compare the gold standard scalp block and bilateral sphenopalatine ganglion block (nasal approach) for attenuation of hemodynamic response to pin insertion. Secondary objectives included hemodynamic response to skin and dural incision. MATERIAL AND METHODS: After IRB approval and informed consent, a prospective randomized comparative study was carried out on 50 adult patients undergoing elective supratentorial surgery. The hemodynamic response to pin insertion, skin incision, and dural incision was noted in both the groups. The data was analyzed with NCSS version 9.0 statistical software. RESULTS: The HR and MAP were comparable between the groups. Following dural incision MAP was significantly lower at 1,2,3,4,5 and 10 min in group SPG whereas in group S it was significantly lower at 1 and 2min. (P = 0.02 at T1, P = 0.03 at T2). CONCLUSIONS: Concomitant use of bilateral SPG block with general anesthesia is an effective and safe alternative technique to scalp blockade for obtundation of hemodynamic responses due to noxious stimulus during craniotomy surgeries.

Pain relief following sternotomy in conventional cardiac surgery: A review of non neuraxial regional nerve blocks.

Acute post-operative pain following sternotomy in cardiac surgery should be adequately managed so as to avoid adverse hemodynamic consequences and pulmonary complications. In the era of fast tracking, adequate and efficient technique of post-operative analgesia enables early extubation, mobilization and discharge from intensive care unit. Due to increasing expertise in ultrasound guided blocks there is a recent surge in trial of bilateral nerve blocks for pain relief following sternotomy. The aim of this article was to review non-neuraxial regional blocks for analgesia following sternotomy in cardiac surgery. Due to the paucity of similar studies and heterogeneity, the assessment of bias, systematic review or pooled analysis/meta-analysis was not feasible. A total of 17 articles were found to be directly related to the performance of non-neuraxial regional nerve blocks across all study designs. Due to scarcity of literature, comments cannot be made on the superiority of these blocks over each other. However, most of the reviewed techniques were found to be equally efficacious or better than conventional and established techniques.

A Comparative Study of Periarticular Infiltration with Dexmedetomidine versus Ketorolac as an Additive to Ropivacaine after Total Knee Arthroplasty: A Prospective, Randomized Double-Blind Study.

BACKGROUND: Periarticular infiltration (PAI) analgesia has been found to be an effective analgesia modality after total knee arthroplasty (TKA). Dexmedetomidine has many beneficial effects on postoperative analgesia by different routes, but studies on PAI are lagging. AIMS AND OBJECTIVES: In this study, we compared postoperative analgesia after PAI with dexmedetomidine versus ketorolac as an additive to ropivacaine after TKA. SETTING AND DESIGN: This is a prospective, randomized, double-blind study conducted on 75 patients belonging to American Society of Anesthesiologists I to III, undergoing total knee arthroplasty, of either gender, belonging to American Society of Anesthesiologists I to III. MATERIALS AND METHODS: After institutional ethics committee approval and written informed consent, patients were randomly allocated into three groups. Group C (n = 25) received cocktail of 60 mL ropivacaine (0.25%) infiltration with adrenaline 5 mL (0.1 mg.mL-1), Group D (n = 25) received additive dexmedetomidine 1 ug.kg-1 to above cocktail, and Group K (n = 25) received ketorolac 30 mg. Postoperatively pain by Visual Analog Scale, vitals, total duration of analgesia, need for rescue analgesia, sedation, patient satisfaction, mobilization time, and complications were recorded. STATISTICAL ANALYSIS: The Statistical Package for the Social Sciences version 20 was used for statistical analysis. Analysis of variance has been used to find the significance of study parameters between the three groups of patients. P < 0.05 was considered statistically significant. RESULTS: Postoperative pain score was lesser in the ketorolac group (1.52 ± 0.71, P = 0.001) than the other two groups. Duration of analgesia was more with ketorolac (343.00 ± 144.45, P < 0.001) compared with the other two groups, and epidural activation timings (462 ± 235.84) were significantly delayed in Group K compared to Group C and Group D. There was no significant difference in mobilization time, patient satisfaction, and complications between the three groups. CONCLUSION: Ketorolac was a better additive to ropivacaine than dexmedetomidine for postoperative analgesia after TKA.

A Prospective Observational Study of Rational Fluid Therapy in Asian Intensive Care Units: Another Puzzle Piece in Fluid Therapy.

INTRODUCTION: Fluid therapy in critically ill patients, especially timing and fluid choice, is controversial. Previous randomized trials produced conflicting results. This observational study evaluated the effect of colloid use on 90-day mortality and acute kidney injury (RIFLE F) within the Rational Fluid Therapy in Asia (RaFTA) registry in intensive care units. MATERIALS AND METHODS: RaFTA is a prospective, observational study in Asian intensive care unit (ICU) patients focusing on fluid therapy and related outcomes. Logistic regression was performed to identify risk factors for increased 90-day mortality and acute kidney injury (AKI). RESULTS: Twenty-four study centers joined the RaFTA registry and collected 3,187 patient data sets from November 2011 to September 2012. A follow-up was done 90 days after ICU admission. For 90-day mortality, significant risk factors in the overall population were sepsis at admission (OR 2.185 [1.799; 2.654], p < 0.001), cumulative fluid balance (OR 1.032 [1.018; 1.047], p < 0.001), and the use of vasopressors (OR 3.409 [2.694; 4.312], p < 0.001). The use of colloids was associated with a reduced risk of 90-day mortality (OR 0.655 [0.478; 0.900], p = 0.009). The initial colloid dose was not associated with an increased risk for AKI (OR 1.094 [0.754; 1.588], p = 0.635). CONCLUSION: RaFTA adds the important finding that colloid use was not associated with increased 90-day mortality or AKI after adjustment for baseline patient condition. CLINICAL SIGNIFICANCE: Early resuscitation with colloids showed potential mortality benefit in the present analysis. Elucidating these findings may be an approach for future research.

Enhanced recovery after surgery: An anesthesiologist's perspective.

Enhanced recovery after surgery (ERAS) protocols are a combination of multimodal evidence-based strategies, applied to the conventional perioperative techniques, to reduce postoperative complications and to achieve early recovery. These strategies or protocols, require a dedicated and organized team effort for their implementation to enable early discharge and thus reduce the length of hospital stay. Anesthesiologists play an important role in facilitating these protocols as some of the key elements such as preoperative patient preparation and assessment, perioperative fluid management, and perioperative pain relief are handled by them. This article discusses in detail the various components of ERAS and the anesthesiologist's role in implementing them.

Evaluation of the Effect of Regional Anaesthesia on Microvascular Free Flaps.

OBJECTIVE: Multiple factors influence the success of microvascular free flap surgeries. Anaesthesia is an important factor to maximise the success rate of microvascular free flaps both by controlling haemodynamics and improving the perfusion of free vascularised tissue. The debate on the usefulness of regional and general anaesthesia for free tissue transfer is ongoing. This retrospective study was conducted to evaluate the effects of regional anaesthesia and other perioperative factors on outcomes of microvascular free flaps. METHODS: This retrospective observational study was conducted on 165 patients undergoing microvascular free flap surgeries between January 2014 and December 2015 after obtaining approval from the Institutional Ethics Committee (Nizams Institute Ethics Committee, Nizams Institute of Medical Sciences, India). Perioperative variables analysed included the type of surgery, indication, ASA physical status, type of anaesthesia, perioperative haemodynamics, fluids used, duration of surgery, re-explorations, blood transfusion and duration of hospital stay. The primary outcome measure was to assess the effect of regional anaesthesia on the success of free flap. RESULTS: Multivariate analysis identified the type of anaesthesia and preoperative haemodynamics as independent risk factors for predicting the failure of flap with an odds ratio of 0.208 and 7.469, respectively. A subgroup analysis of 55 acute trauma patients revealed preoperative haemodynamic instability as an individual independent risk factor for graft failure with an odds ratio of 11.90. CONCLUSION: The results of this study emphasise the importance of the choice of anaesthesia and preoperative optimisation in improving the success of free flap surgeries.

Autonomic disturbances in diabetes: Assessment and anaesthetic implications.

Diabetes mellitus is the most common medical condition and with increased awareness of heath and related issues, several patients are getting diagnosed with diabetes. The poor control of sugar and long-standing status of disease affects the autonomic system of body. The autonomic nervous system innervates cardiovascular, gastrointestinal, and genitourinary system, thus affecting important functions of the body. The cardiovascular system involvement can manifest as mild arrhythmias to sudden death. Our search for this review included PubMed, Google Search and End Note X6 version and the key words used for the search were autonomic neuropathy, diabetes, anesthesia, tests and implications. This review aims to highlight the dysfunction of autonomic system due to diabetes and its clinical presentations. The various modalities to diagnose the involvement of different systems are mentioned. An estimated 25% of diabetic patients will require surgery. It has been already established that mortality rates in diabetic patients are higher than in nondiabetic patients. Hence, complete workup is needed prior to any surgery. Diabetic autonomic neuropathy and its implications may sometimes be disastrous and further increase the incidence of in hospital morbidity and mortality. Overall, complete knowledge of diabetes and its varied effects with anaesthetic implications and careful perioperative management is the key guiding factor for a successful outcome.

Prediction of Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) after Thoracic Surgery- The Role of Estimated GFR.

INTRODUCTON: Little is known about the prognostic utility of preoperative estimated GFR (eGFR) on perioperative Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) in apparently lower risk patients undergoing moderate risk surgeries like thoracotomy. AIM: The current study sought to identify a clinically relevant cut-off value of eGFR for identifying thoracotomy patients at higher risk for MACCE. MATERIALS AND METHODS: Between July 2012 and July 2016, 436 consecutive patients were retrospectively studied after elective thoracotomy in a single institution. Patients were classified into six groups according to the calculated Chronic Kidney Disease Epidemiology Collaboration equations (CKD-EPI) eGFR (ml min -11.73 m -2): Stage 1, eGFR >90; Stage 2, eGFR=60-89.9; Stage 3a, eGFR=45-59.9; Stage 3b, eGFR=30-44.9; Stage 4, eGFR=15-29.9; Stage 5, eGFR <15. All the eGFR groups were analysed for perioperative MACCE, length of hospital stay, and mortality. RESULTS: The incidence of perioperative MACCE in our study was 4.24%. The mean eGFR in our study as calculated by the CKD-EPI equation was 83 ml min-11.73 m-2. With the exception of nonfatal cardiac arrest which was not seen in any patient, the incidence of all MACCE increased with progressively worsening preoperative eGFR.It was seen by logistic regression analysis that the occurrence of any perioperative MACCE increased significantly with worsening eGFR (p<0.001). The increase in MACCE was particularly marked from Stage 3b onwards to the later stages (OR 1.9 in 3a vs. 3.6 in 3b). The two mortalities observed in the study were in Stages 4 and 5 with no deaths seen in the better eGFR subgroups. There was also an increased length of hospital stay with declining eGFR. CONCLUSION: Preoperative eGFR is a predictor of perioperative MACCE in homogenous moderate risk elective surgical population like thoracic surgeries. There is an inverse relationship between eGFR and MACCE, particularly manifested at eGFR values <45 ml/min/1.73. Routine use of preoperative eGFR for cardiovascular and cerebrovascular risk assessment in patients undergoing moderate risk surgeries like thoracotomy would be beneficial.

Comparison of volume control and pressure control ventilation in patients undergoing single level anterior cervical discectomy and fusion surgery.

BACKGROUND AND AIMS: Pressure control and volume control ventilation are the most preferred modes of ventilator techniques available in the intraoperative period. The study compared the intraoperative ventilator and blood gas variables of volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV) in patients undergoing single level anterior cervical discectomy and fusion (ACDF). METHODS: After obtaining Institutional Ethical Committee approval and informed consent, sixty patients scheduled for single level ACDF surgery performed in supine position under general anaesthesia were included. Group V (30 patients) received VCV and Group P (30 patients) received PCV. The primary objective was oxygenation variable PaO2/FiO2 at different points of time i.e. T1-20 min after the institution of the ventilation, T2-20 min after placement of the retractors and T3-20 min after removal of the retractors. The secondary objectives include other arterial blood gas parameters, respiratory and haemodynamic parameters. NCSS version 9 statistical software was used for statistics. Two-way repeated measures for analysis of variance with post hoc Tukey Kramer test was used to analyse continuous variables for both intra- and inter-group comparisons, paired sample t-test for overall comparison and Chi-square test for categorical data. RESULTS: The primary variable PaO2/FiO2 was comparable in both groups (P = 0.08). The respiratory variables, PAP and Cdynam were statistically significant in PCV group compared to VCV (P < 0.05), though clinically insignificant. Other secondary variables were comparable. (P > 0.05). CONCLUSION: Clinically, both PCV and VCV group appear to be-equally suited ventilator techniques for anterior cervical spine surgery patients.

Comparison of ease of intubation in sniffing position and further neck flexion.

BACKGROUND AND AIMS: Optimization of patient's head and neck position for the best laryngeal view is the most important step before laryngoscopy and intubation. The objective of this prospective crossover study was to determine the differences, if any, between the gold standard sniffing position (SP) and the further head elevation (HE) (neck flexion) with regard to the incidence of difficult laryngoscopy, intubation difficulty, and variables of the I ntubation Difficulty Scale (IDS) in adult patients undergoing elective surgery under general anesthesia. MATERIAL AND METHODS: In the "SP" the neck must be flexed on the chest by elevating the head with a cushion under the occiput and extending the head at the atlanto-occipital joint. Our study was carried out to evaluate the glottic view in SP compared to further HE by 1.5 inches during direct laryngoscopy in elective surgeries. Patients were randomly assigned to either Group A ("SP" during first laryngoscopy and "HE" during second laryngoscopy) or vice versa in Group B. The effect of patient position on ease of intubation was assessed using a quantitative scale - The intubation difficulty scale (IDS). RESULTS: There were significant differences with regard to glottic visualization (P = 0.00), number of operators (P = 0.001), laryngeal pressure (P = 0.00), and lifting force (P = 0.00) required for intubation and IDS (P = 0.00), thus favoring further HE position. CONCLUSION: We conclude that the HE position is superior to standard SP with regard to ease of intubation as assessed by IDS.
