Use of Pre?Operative Hemoglobin A1c to Predict Early Post?Operative Renal Failure and Infection Risks in Patients who are not Diabetics and Undergoing Elective off Pump Coronary Artery Bypass Graft Surgery

Background: Recent studies have indicated that patients, both with and without diabetes with an increased HbA1c, have a higher rate of adverse outcomes following cardiac surgeries. Our study is focused on to evaluate the prognostic impact of admission value of HbA1c in non?diabetic patients for postoperative renal failure and infections. Materials and Methods: Plasma HbA1c levels were collected from 200 consecutive nondiabetic patients who got admitted for elective off pump coronary artery bypass graft (CABG) procedure over a 2?year period under two groups, Group A whose HbA1c was < 6% at admission and Group B whose HbA1c was ?6% and ?6.4% at admission. After surgery, patients were followed up to see if they have got infection or renal failure as postoperative complication. Student抯 unpaired t test was used to test the significance of difference between the quantitative variables, Yate抯 and Fisher抯 chi square tests were used for qualitative variables. Results: We found early postoperative renal failure in 14 (3/96 in Group A and 11/104 in Group B) out of 200 patients (7%) and infection in 21 (8/96 in Group A and 13/104 in Group B) out of 200 patients (10.5%). After data analysis, it was noted that there is a positive correlation between HbA1c and postoperative renal failure (P = 0.0213) whereas no association was found between HbA1c and postoperative infections (P = 0.175) in patients undergoing off?pump CABG surgery. Conclusion: In patients without diabetes, a plasma HbA1c ?6% was a significant independent predictor for early postoperative renal failure.

Attenuation of hemodynamic responses to laryngoscopy and intubation by pre-operative oral melatonin

Background: Laryngoscopy and endotracheal intubation are usually associated with tachycardia and hypertension. Pre-administration of melatonin has anxiolytic and sedative property which can reduce the tachycardia and hypertension during the surgical procedures. Aims and Objectives: The present study aimed to evaluate the melatonin effect on hemodynamic changes during laryngoscopy and intubation. Materials and Methods: This prospective study was done in the department of anesthesia, Sri Jayadeva Institute of Cardiovascular Sciences and Research, Bengaluru, Karnataka. Total 80 patients were included in the study based on the inclusion and exclusion criteria. Patients were divided into two groups. Group-A treated with placebo and Group-B treated with melatonin (6 mg) and demographic, clinical, and hemodynamic parameters were recorded. The data were analyzed with unpaired t-test with the use SPSS (20.0) version software. Results: Comparison of number and percentage of age, gender, and blood groups between the Group-I and Group-II not showed any significant difference. Group-I and Group-II mean age, height, and weight not showed any significant difference. Mean heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure were compared between the Group-I and Group-II at basal, during, after 1, 3, 5, and 10 min showed significant difference. Conclusion: Pre-administration melatonin showed significant reduction of hemodynamic changes compared to placebo group.

Clinical results of combined penetrating keratoplasty and vitreoretinal surgery / Resultados clínicos da combinação de ceratoplastia penetrante e cirurgia vitreorretiniana

ABSTRACT Purpose: The study aimed to assess the anatomical and functional success rates of penetrating keratoplasty with temporary keratoprosthesis-assisted vitreoretinal surgery. Methods: This retrospective study included 15 eyes of 14 patients, recording demographic characteristics, pre-operative anterior and posterior segment pathologies, intraoperative complications, postoperative graft status, retinal attachment, and complications and evaluating anatomical and functional success rates. Results: The mean follow-up period was 29.8 ± 19.1(6-60) months. The most common pre-operative corneal pathology was graft abscess (7 eyes [46.7%]), and the most common diagnosis of the posterior segment was endophthalmitis (7 eyes [46.7%]). Five (33.3%) cases had visual acuity between 0.001-0.08. Pre-operative endophthalmitis was diagnosed in all five cases with anatomical failure.Conclusion: Temporary keratoprosthesis-assisted vitreoretinal surgery with penetrating keratoplasty is an effective method to treat acute/subacute pathologies of the concomitant anterior and posterior segment. However, results may vary on a case-by-case basis. Pre-operative endophthalmitis is a poor prognostic factor for long-term success.

RESUMO Objetivo: Avaliar as taxas de sucesso anatômico e funcional da ceratoplastia penetrante associada à cirurgia vitreorretiniana assistida por ceratoprótese temporária. Métodos: Foram incluídos neste estudo retrospectivo 15 olhos de 14 pacientes. Registraram-se as características demográficas, as patologias pré-operatórias dos segmentos anteriores e posteriores, as complicações perioperatórias, a condição pós-operatória do implante e a fixação e as complicações da retina. Foram avaliadas as taxas de sucesso anatômico e funcional. Resultados: O período médio de acompanhamento foi de 29,8 ± 19,1(6-60) meses. A patologia corneana pós-operatória mais comum foi o abscesso do implante (7 olhos, 46,7%) e o diagnóstico mais comum no segmento posterior foi a endoftalmite (7 olhos, 46,7%). Cinco casos (33,3%) mostraram acuidade visual entre 0,001 e 0,08. Foi diagnosticada endoftalmite pré-operatória em todos os 5 casos com insucesso anatômico. Conclusão: A cirurgia vitreorretiniana assistida por ceratoprótese temporária associada à ceratoplastia penetrante é um método eficaz de tratamento de patologias agudas e subagudas concomitantes nos segmentos anterior e posterior. Porém, os resultados podem variar de caso a caso. A endoftalmite pré-operatória é um fator de pior prognóstico de sucesso de longo prazo.

Role Of Raised C-Reactive Protein (CRP) As the Indicator for Surgical Intervention in Clinically Diagnosed Acute Appendicitis

Background: The diagnosis of acute appendicitis relies more on the clinical acumen of the surgeon than on the investigations. As the condition is associated with an acute-phase reaction the analysis of WBC, neutrophil percentage and serum level of CRP has been demonstrated to be important diagnostic tools. Surprisingly the level of CRP becomes proportionately raised with increasing severity of the histopathological variety of the appendix. Aim of the study: The aim of this study was to compare the preoperative CRP level with postoperative histological findings and find out a predictive value of CRP as an indicator for surgical intervention in acute appendicitis.Material & Methods:It was a prospective, cross-sectional, observational study executed in the Department of Surgery, Dhaka Medical College Hospital from January to December of 2015 where 107 patients were included in this study. Preoperative level of CRP and WBC count was done in all selected patients. Histopathological severity of the resected specimen of the appendix was determined postoperatively. The correlation between preoperative clinical factors and the actual histological severity and identification of surgical indication markers was assessed to determine whether only the CRP level significantly differs between the surgical treatment necessary group and the possible non-surgical treatment group.Results:54% (58) of the patients were female out of a total of 107. Peak incidence (25.2%) was in the 16-20 years age group. Neither age nor gender had any significance with the type of appendicitis. Among the patients 28.1% (30) had gangrenous appendicitis. In patients with histopathologically proven acute appendicitis, both the WBC count and serum CRP level were raised. But only the CRP level significantly differs between gangrenous appendicitis and uncomplicated appendicitis (p-value<0.0001). The specificity and sensitivity of serum CRP for gangrenous appendicitis were 97% and 71% respectively. The ROC curve indicated that the cutoff value of CRP for gangrenous appendicitis is 6.2 mg/dl. Conclusions:A normal pre-operative serum CRP measurement in patients with suspected acute appendicitis is most likely associated with a normal or uncomplicated inflammation of the appendix. The rate of unnecessary appendectomies would probably reduce in this patient group by deferring surgery. Only the CRP level is consistent with the severity of appendicitis and can be considered to be a surgical indication marker for acute appendicitis.

Incidencia de hipotermia perioperatoria inadvertida, en perros sometidos a anestesia general inhalatoria / Incidence of inadvertent perioperatory hypothermia, in dogs submitted to inhalation general anesthesia

RESUMEN La incidencia de hipotermia perioperatoria inadvertida es una de las principales complicaciones perianestésicas en caninos. El objetivo del presente estudio fue evaluar la incidencia de hipotermia perioperatoria inadvertida en 49 perros sometidos a anestesia general inhalatoria. Al finalizar el periodo preanestésico, transanestésico y postanestésico, se registró la temperatura corporal, de acuerdo con los siguientes rangos: hipertermia (>39,5°C), normotermia (38,5-39,5°C), hipotermia leve (38,4-36,5°C), hipotermia moderada (36,4-34,0°C), hipotermia severa (<34°C). En preanestesia, el 65% de los animales mostraron hipotermia leve y 2% hipotermia moderada. En transanestesia, 55% de los animales tuvieron hipotermia leve, 37% hipotermia moderada y 6,1% hipotermia severa. En postanestesia, 59% de los animales tuvieron hipotermia leve, 29% hipotermia moderada y 6% hipotermia severa. Se encontraron diferencias al comparar la temperatura basal, con la final transanestésica y postanestésica, respectivamente (p<0,001); del mismo modo, se obtuvieron diferencias al comparar la temperatura inicial, con la final del periodo transanestésico (p<0,001). Por otra parte, no hubo relación estadística entre las diferentes clasificaciones ASA, los procedimientos realizados, el sexo y los rangos etarios evaluados, así como tampoco hubo diferencia en el tiempo de extubación frente al tipo de procedimiento realizado. Los resultados de este estudio sugieren que, bajo las condiciones aquí planteadas, la incidencia de hipotermia preanestésica es mínima, mientras la aparición de hipotermia transanestésica y postanestésica de carácter leve, moderada y severa es mayor.

ABSTRACT The incidence of inadvertent perioperative hypothermia is one of the main perianesthetic complications in canines. The objective of the present study was to evaluate the incidence of inadvertent perioperative hypothermia in 49 dogs undergoing inhalation general anesthesia. At the end of the pre-anesthetic, trans-anesthetic, and post-anesthetic periods, body temperature was recorded, according to the following ranges: hyperthermia (>39.5°C), normothermia (38.5-39.5°C), mild hypothermia (38,4-36.5°C), moderate hypothermia (36.4-34.0°C), severe hypothermia (<34°C). In pre-anesthesia, 65% of the animals showed mild hypothermia, and 2% moderate hypothermia. In transanesthesia, 55% of the animals had mild hypothermia, 37% moderate hypothermia, and 6% severe hypothermia. In post-anesthesia 59% of the animals had mild hypothermia, 29% moderate hypothermia, and 6% severe hypothermia. Differences were found when comparing the basal temperature with the final trans-anesthetic and post-anesthetic respectively (p<0.001); Similarly, differences were obtained when comparing the initial temperature with the end of the trans-anesthetic period (p<0.001). On the other hand, there was no statistical relationship between the different ASA classifications, the procedures performed, sex, and the evaluated age ranges; as well as there was no difference in the extubation time compared to the type of procedure performed. The results of this study suggest that, under the conditions outlined here, the incidence of pre-anesthetic hypothermia is minimal, while the appearance of mild, moderate, and severe trans-anesthetic and post-anesthetic hypothermia is higher.

Introduction: The disease by the new coronavirus 2019 (COVID-19) emerged in China and spread globally with sustained worldwide transmission from human to human. The COVID-19 IgM/IgG rapid diagnostic tests performed at the time of hospital admission, before elective surgery, are among the most widely used pre-operative screening methods. Objectives: This study aims to evaluate the role of the rapid test of COVID-19 antibodies as screening in outpatients in aesthetic plastic surgery. Methods: A systematic review was carried out for studies published since December 2019, with several search terms related to the rapid antibody test for COVID-19 and SARS-CoV-2. The relevant articles were selected through the evaluation of titles and abstracts. Relevant articles have been revised. Data on the level of evidence, sensitivity, and specificity were collected. Results: The review strategy produced 409 manuscripts. A total of 357 studies were duplicated or proved to be irrelevant to the research question. Among the remaining articles, 28 were studies without precision information, and 24 were manuscripts describing precision measures. The sensitivity varied from 18.4 to 100%; the positive predictive value between 19.7 and 100%; specificity between 94 and 100%; and the negative predictive value between 20 and 100%. Conclusion: COVID-19 IgM / IgG rapid diagnostic tests may be inaccurate. We found no evidence to support the rapid antibody test COVID-19 or SARS-CoV-2 for outpatients in cosmetic plastic surgery.

Correlation between Surgical Risk Scales with Respiratory Muscle Strength and Functional Independence in Patients Submitted to Coronary Artery Bypass Grafting

Abstract Background The European Heart Surgery Risk Assessment System (EuroSCORE) and InsCor have been used to predict complications of cardiac surgery. However, their application to predict lung function and functionality is still uncertain. Objective To correlate surgical risk scales with functional independence and pulmonary function in patients undergoing coronary artery bypass grafting. Methods This was a prospective cohort study. In the preoperative period, the two surgical scales were applied, the maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and peak expiratory flow (PEF) were measured, and functionality was assessed using the functional independence measure (FIM). On the seventh postoperative day, the pulmonary function and functionality variables were reevaluated, compared with the preoperative values (delta) and correlated with the risk scales. Correlations of pulmonary function, functional independence and muscle strength variables with the surgical scales were made by Pearson correlation test. The significance level adopted was 5%. Results Thirty-one patients were studied; most were male (77%), with a mean age of 56±8 years. Mean EuroSCORE was 2.3±0.5 and mean InsCOR was 1.2±0.5. MIP, MEP, and PEF reduced 30% (p<0.001), 33% (p<0.001) and 10% (p=0.23), respectively. The EuroSCORE correlated with MIP (r-0.78; p = 0.02) and FIM (r-0.79; p <0.01), and the InsCor correlated with MIP (r-0.77), MEP (r-0.73) and MIF (r-0.89; p=0.02). Conclusion The EuroSCORE showed a strong negative correlation with MIP and FIM, while InsCor had a strong negative correlation with MIP, MEP and FIM.

Preoperative Planning of Acetabular Arc Osteotomy Using Finite Element Method / 医用生物力学

Objective In order to simulate different angles of acetabular blocks that need to be adjusted during operation, the optimal angle was determined through analyzing the contact stress and contact area of cartilage around the hip joint, so as to provide an individual scheme for acetabular osteotomy. Methods The finite element models for development dysplasia of hip (DDH) and normal pelvis were established to investigate morphological characteristics of the acetabulum and the causes of stress concentration. To simulate osteotomy for the DDH model, a total of 20 postoperative osteotomy models were obtained through the combination of different angles for anterior rotation and lateral rotation of acetabular blocks, and the differences in optimal results of the models during simulated one legged-standing were compared and analyzed. Results The maximum contact pressure of acetabular cartilage in normal model was 7.85 MPa. The maximum contact pressure of acetabular cartilage in DDH model was 13.42 MPa. The optimal contact pressure after simulated osteotomy decreased to 8.49 MPa, and the contact distribution was improved more significantly. Conclusions Changing the anterior rotation angle can significantly improve the contact pressure distribution and size, as well as stay away from the preoperative lesion area, which has a positive impact on postoperative outcomes. Personalized osteotomy plan based on actual situation of each patient before the operation is crucial for the surgical effect.

Various modalities surgeries have come into place in recent times. However preparing a patient physically and mentally needs a thorough pre-operative preparation. Here in this review, we are exploring the approach to patient with morbid obesity and work up for bariatric surgery from a physician’s point of view.

Evaluation of the role of pre-operative albumin and its post-operative drop in the prediction of outcomes of emergency laparotomy

Background: Laparotomies are commonly performed surgeries in an emergency setting. The complications associated with these are a result of the activation of the surgical stress response, the magnitude and duration of which are proportional to the surgical injury. Albumin is an important negative phase reactant. This study was an attempt to evaluate the effectiveness of measurement of pre-operative albumin and the post-operative drop in albumin levels in the prediction of post-operative morbidity and mortality following laparotomy.Methods: Albumin levels of 50 patients undergoing emergency exploratory laparotomy in Victoria Hospital were measured pre and post operatively. The percentage drop in albumin levels was noted. The outcomes were noted and classified according to Clavein Dindo Classification. Unpaired t-test and ANOVA test was used for statistical analysis. A p value of <0.05 was considered statistically significant.Results: 62% of the patients had hypoalbuminemia preoperatively. 58% of patients had post-operative complications. The mean preoperative albumin levels for patients without complications was 3.83 while that for patients with complications was 2.78 (p<0.05). The mean percentage drop in albumin values was 9.66% for patients without complications while it ranged from 14.79 (Clavein Dindo 1) - 24.27 (Clavein Dindo 5) for patients with complications (p=0.047). A negative correlation was noted between the preoperative albumin values and the duration of hospital stay while the drop in albumin levels showed a positive correlation with the duration of hospital stay.Conclusions: Measurement of albumin levels pre-operatively and in the immediate post-operative period following laparotomy can prove as a useful tool and an early indicator of morbidity and mortality following laparotomy.

Can difficulties in laparoscopic cholecystectomy be anticipated preoperatively: evaluation of a scoring system

Background: Laparoscopic cholecystectomy is often associated with intra operative difficulties leading to increased intra and post-operative morbidity. Accurate prediction of a difficult laparoscopic cholecystectomy can reduce the complication rate, rate of conversion and overall medical cost. This study was an attempt to validate a scoring system developed to predict difficult laparoscopic cholecystectomy.Methods: 100 patients undergoing laparoscopic cholecystectomy were included. Details such as age, sex, BMI, previous surgical history, history of hospitalisation for biliary disease, sonographical wall thickness, pericholecystic collection and presence of impacted stone were noted. With these, pre-operative score was calculated using the scoring system. Intra operative details and complications were noted and were classified as easy, difficult and very difficult. Student t test and chi square test was used to test the difference of significance (p<0.05).Results: Male sex, higher BMI, a history of previous surgery, a history of prior hospitalisation for biliary disease, a palpable gall bladder, a thickened gall bladder wall, impacted stone and pericholecystic collection all had a statistically significant accurate prediction of the difficulty in laparoscopic cholecystectomy. The mean duration of surgery was 62.7±33.15 minutes. The scoring system developed by Randhawa et al predicted difficult laparoscopic cholecystectomy with a sensitivity of 77.8%, specificity of 78.1%, positive predictive value of 66.7% and a negative predictive value of 86.2%.Conclusions: The proposed scoring system predicted difficult laparoscopic cholecystectomy with a sensitivity of 77.8%, specificity of 78.1%, positive predictive value of 66.7% and a negative predictive value of 86.2%.

Pre-Operative Embolisation of Musculoskeletal Tumours - A Single Centre Experience

@#Introduction:The management of musculoskeletal tumours is complex and requires a multi-disciplinary approach. Preoperative embolisation can be often employed to reduce intra-operative blood loss and complication rates from surgery. We report our experience with the safety, technical success and efficacy of pre-operative embolisation in musculoskeletal tumours. Materials and Methods:Thirteen consecutive patients who underwent pre-operative embolisation of a musculoskeletal tumour followed by surgical intervention at our institution from May 2012 to January 2016 were enrolled into the study. Patient demographics, tumour characteristics, embolisation techniques and type of surgery were recorded. Technical success of embolisation, amount of blood loss during surgery and transfusion requirements were estimated. Results: There were five female and eight male patients who underwent pre-operative embolisation during the study period. The age ranged between 16 to 68 years, and the median age was 54. Technical success was achieved in all patients. Mean intra-operative blood loss was 1403ml, with a range of 150ml to 6900ml. Eight patients (62%) required intra-operative blood products of packed red blood cells and fresh frozen plasma. No major complications occurred during embolisation. Conclusion: Pre-operative trans-arterial embolisation is feasible and safe for a variety of large and hypervascular musculoskeletal tumours. Our small series suggests that preoperative embolisation could contribute to the reduction of the intra-operative and post-operative blood product transfusion. It should be considered as a pre-operative adjunct for major tumour resections with a high risk of bleeding. The use of the haemoglobin gap complemented the assessment of perioperative blood loss.

Effect of a Single Pre-Operative Dose of Dexmedotomidine Versus Fentanyl on Anesthetic Requirement and Peri- Operative Hemodynamic Stress Response

Background: Dexmedetomidine has sympatholytic, ant nociceptive, sedative, and anti-sialagogue properties without causing respiratory depression. Dexmedetomidine is the active d-isomer of medetomidine, that is a selective and specific α2-adrenoceptor agonist. It acts by the central sympatholytic action. So it provides haemodynamic stability. It has both analgesic as well as anaesthetic sparing property. Dexmedetomidine is also an effective sedative. Methods: Study Population:- Two groups were included in this study.49 cases were included in group II & 50 cases were included in group II.The duration of study was over a period of 6 month.This study was conducted in the Department of Anesthesia in Carrier Institute of Medical Sciences, Lucknow. Results: This result revealed that adverse effect of bradycardia was seen only in one patient. None of the patients was sedated after discontinuation of anesthesia. Conclusion: This study concludes that, during laryngoscopy and in the perioperative period, a single pre-operative dose of Dexmedetomidine provides better hemodynamic stability in comparison to Fentanyl by attenuation of sympathoadrenal response.

Pre-operative hypertension and its risk factors: A cross-sectional study among patients admitted for surgery at a tertiary health care facility of Eastern India

Background: Hypertension (HTN) is one of the most common diagnoses in a primary health care setting and it is one of the important and preventable contributors to disease and death. HTN is considered as an additional risk factor in anesthesia and HTN is of special importance to the anesthetist for various reasons. Tracheal intubation, surgical incision, recovery from anesthesia, and post-operative pain can increase blood pressure (BP). Objectives: This study aims to find out the burden of pre-operative HTN and its risk factors among patients who were admitted for surgical procedures at a tertiary health care facility of Durgapur, West Bengal, India. Materials and Methods: After obtaining permission from the Institutional Ethics Committee, an institution based, observational, and cross-sectional study was conducted from January 2019 to February 2019. A pre-tested, semi-structured schedule was used to collect Clinic Social data. Anthropometric measurements and BP were taken as per the world health organization STEP-wise approach to surveillance guidelines. BP was classified as per “The eighth joint national committee (JNC-8) guidelines. Results: Data were collected from 150 study subjects and were analyzed using SPSS, version 20.0 for windows. The frequency of pre-operative HTN and pre-HTN was found to be 38.0% and 32.0% respectively. As per JNC-8, 34.7% had Stage-1 HTN followed by 32.0% and 3.3% who had pre-HTN and Stage-2 HTN, respectively. Increasing age, male gender, smoking, increasing body mass index, dyslipidemia, and Type 2 diabetes mellitus (T2DM) were significantly associated with a higher frequency of HTN. Conclusion: There is a very high prevalence of pre-operative HTN and pre-HTN. Increasing age, male gender, smoking, overweight, obesity, dyslipidemia, and T2DM were significant risk factors for HTN. Routine screening of HTN should be done in surgical ward to see if there are cases of “white coat” HTN.

Per speculum examination was done and PAP smear was taken before bimanual examination was done. A complete per vaginum examination was done and the adnexal mass was assessed for its size, side, consistency, laterality and tenderness. Laparoscopy was done to confirm preoperative diagnosis and appropriate procedure done depending on diagnosis.Results: Pain in the lower abdomen was the commonest chief complaint seen in 87.5% cases. 41.67% cases were suspected to have endometriosis while on laparoscopy it was seen in 47.92%, 33.33% were suspected to have ovarian cyst which decreased to 25% on laparoscopy, ectopic pregnancy in 16.67% cases both pre-operative and on laparoscopic examination and tubo-ovarian mass in 8.33% cases pre-operatively and 2.08% on laparoscopy.Conclusions: This study has shown that if proper preoperative evaluation was done, author can select the appropriate patients for laparoscopic approach.
