Dengue and HELLP: Beware of the Masquerade.

HELLP is a syndrome characterized by hemolysis, elevated liver enzymes, and low platelets. It is a rare complication of pregnancy and is usually associated with pre-eclampsia. However, 10-20% cases of HELLP can present without hypertension. Dengue fever is an arboviral-borne tropical illness that is characterized with fever, thrombocytopenia, and bleeding manifestations. We present a case of a primigravida with HELLP syndrome masquerading in the background of dengue fever. Unique features to this case report include delayed presentation of HELLP syndrome with normotension which can have overlapping features with dengue fever, especially in term pregnancy. This case highlights the need of strict vigilance in cases of dengue fever with pregnancy. How to cite this article: Patnaik R, Kulkarni S, Karan N. Dengue and HELLP: Beware of the Masquerade.

Incidence, risk factors and impact of anemia after elective neurosurgery: A retrospective cohort study.

Objectives: Anemia after surgery is common and is associated with adverse clinical outcomes. Understanding the incidence and risk factors for postoperative anemia is important to reduce anemia-related complications and blood transfusion. There is lack of data regarding postoperative anemia and its contributing factors in neurosurgery. This study evaluates the incidence and risk factors of postoperative anemia, and its impact on clinical outcomes. Methods: This was a single centre, retrospective study of patients who underwent elective neurosurgery over seven months. Data regarding age, gender, body mass index, American Society of Anesthesiologists (ASA) physical status, diagnosis, surgery, preoperative hemoglobin, surgery duration, intraoperative blood loss and red blood cell (RBC) transfusion, dose of tranexamic acid, intraoperative fluid balance, years of surgeon's experience, postoperative hemoglobin, postoperative RBC transfusion, Glasgow Coma Scale (GCS) score at hospital discharge, and duration of postoperative intensive care unit and hospital stay were collected. Logistic regression was used to identify predictors of postoperative anemia. Results: The incidence of postoperative anemia was 11.3% (116/1025). On univariate analysis; age, preoperative hemoglobin, surgery duration, gender, ASA grade, surgery type, and surgeon's experience were associated with postoperative anemia. Lower preoperative hemoglobin (p<0.001) and non-tumor surgery (p<0.001) were predictive of postoperative anemia on multivariate analysis. Postoperative anemia resulted in increased RBC transfusion (p<0.001) and lower GCS score at discharge (p=0.012). Conclusions: Atleast one in ten patients undergoing elective neurosurgery develop postoperative anemia. Lower preoperative hemoglobin and non-tumor surgery predict anemia. Anemia results in increased RBC transfusion and lower discharge GCS score.

Postoperative delayed neurocognitive recovery: Evaluation of its incidence and correlation with intraoperative cerebral desaturation - A prospective observational study.

BACKGROUND: Delayed neurocognitive recovery (DNR) is commonly seen in patients in the postoperative period. Literature has shown that monitoring cerebral desaturation intraoperatively can predict the development of DNR in elderly patients undergoing surgery in prone position. This prospective observational study was conducted in patients of all ages, with the primary objective to determine the incidence of DNR and its correlation with cerebral oximetry. The secondary objectives were to determine if intraoperative cerebral desaturation influenced the neuropsychometric variables from preoperative to postoperative period. METHODS: This study included 61 patients, aged > 18 years undergoing spinal surgery in prone position. An evening before surgery and at 48 h postoperatively, patients were subjected to neuropsychological examination; Hindi Mental State Examination, Colour Trail Test 1 (CTT 1), CTT 2, Auditory Verbal Learning (AVLT) tests conducted by principal investigator (PI). DNR was defined as a 20% change in any of the test scores from the baseline. rSO2 was recorded bilaterally every 10 min throughout surgery by an independent person. Cerebral desaturation was defined as a 20% drop in rSO2 from the control value. RESULTS: The incidence of DNR was 24.6%. The duration of anesthesia and cerebral desaturation were found to be independently predictive of DNR, with each hour of anesthesia causing a two-fold increase in the chances of development DNR (P = 0.019) and presence of cerebral desaturation causing a 6-fold increase (P = 0.039). CTT 1 and CTT 2 tests had significantly larger increase in test scores in the postoperative period, in patients with cerebral desaturation. CONCLUSION: Duration of anesthesia and cerebral desaturation were factors predictive of the development of DNR in patients undergoing spine surgery in prone position.

Posterior Reversible Encephalopathy Syndrome After Epilepsy Surgery Alerted by Low-Processed Electroencephalography Levels: A Case Report.

The development of posterior reversible encephalopathy syndrome (PRES) in a patient undergoing epilepsy surgery without perioperative hypertension is uncommon. A young man having epilepsy surgery with normal blood pressures had an unexplained drop in his processed electroencephalogram (pEEG) levels intraoperatively. This alerted and prompted us to search for the cause. A postoperative electroencephalogram (EEG) confirmed a diffuse slowing of cortical waves. The intraoperative findings of pEEG, magnetic resonance imaging (MRI), and EEG postoperatively prompted a diagnosis of PRES. The patient was managed conservatively and had a full recovery. This case report highlights the role of brain electrical activity monitors in PRES.

Access to pain medicines and follow-up consultation after radiofrequency ablation for trigeminal neuralgia during the COVID-19 pandemic.

Background: In the recent coronavirus disease 2019 (COVID-19) pandemic, follow-up of patients with trigeminal neuralgia post radio-frequency ablation (RFA) of the Gasserian ganglion was restricted because of closure of pain clinic services (PCSs) at our institution, travel restrictions, and fear of contracting COVID-19 infection by hospital visit. Periodic follow-ups are a must in this group of patients. Because the access to pain medications and consultations remained restricted, we tried identifying the factors predisposing to these difficulties in patients. Methods: We had contacted patients telephonically, who underwent RFA at our institution in the past 5 years as the PCS had not re-started to follow up with in-person consultation. Demographics, socio-economic factors, clinical factors, literacy status, distance to the health care system, and current health status were noted. Collected data were analyzed descriptively, and correlations were calculated between the predictors for difficulty in follow-up to access the medications and consultations. Results: Out of 121 patients who underwent RFA in the past 5 years, 73 were accessible on phone. Of these, 42.46% (31/73) patients had difficulty in accessing either medications or consultation. The literacy status of the patient was the strongest predictor (0.044) with a negative correlation (-1.216). Difficulty in accessing PCS was associated with a poor health status (p-0.032) and higher pain scores (0.066). Conclusion: Along with the clinical factors, we have to overlook other factors in predicting difficulty to access PCS in trigeminal neuralgia patients post the RFA status. Difficulty in access to pain medicines and/or consultations was associated with a poor health status and higher pain scores.

Electroconvulsive therapy services during COVID-19 pandemic.

The COVID-19 pandemic has hit the electroconvulsive therapy (ECT) services hard worldwide as it is considered an elective procedure and hence has been given less importance. Other reasons include the risk of transmission of infections, lack of resources, and the scarcity of anesthesiologists due to their diversion to intensive care units to manage COVID-19 patients. However, ECT is an urgent and life-saving measure for patients diagnosed with depression and other severe mental illnesses who have suicidality, catatonia, or require a rapid therapeutic response. COVID-19 pandemic is a significant source of stress for individuals due to its impact on health, employment, and social support resulting in new-onset psychiatric illnesses and the worsening of a pre-existing disorder. Hence, a continuation of the ECT services during the COVID-19 pandemic is of paramount importance. In this narrative review, the authors from India have compiled the literature on the ECT practice during the COVID-19 pandemic related to the screening and testing protocol, necessity of personal protective equipment, modification in ECT Suite, electrical stmulus settings, and anesthesia technique modification. The authors have also shared their experiences with the ECT services provided at their institute during this pandemic. This description will help other institutes to manage the ECT services uninterruptedly and make ECT a safe procedure during the current pandemic.

Evaluation and validation of Physiological and Operative Severity Score for the enumeration of mortality and morbidity and Portsmouth-POSSUM scores in predicting morbidity and mortality in patients undergoing head and neck cancer surgeries.

BACKGROUND: Identification of risk factors for perioperative complications helps in the prognostication. We wanted to determine whether Physiological and Operative Severity Score for the enumeration of mortality and morbidity (POSSUM) and Portsmouth-POSSUM (P-POSSUM) can be used in patients undergoing head and neck oncosurgery. METHODS: We conducted a retrospective analysis of 1265 patients after they had major head and neck oncosurgeries. Demographic, surgical and outcome data was collected. We separately analyzed data for patients who had undergone cancer surgery for oral cavity, pharynx, and larynx. We calculated the POSSUM and P-POSSUM scores. RESULTS: POSSUM scoring system had moderate discrimination (AUC = 0.61) and good calibration (P = .36) for the entire study cohort and in the subgroup. Since there were no deaths in the entire cohort, we were not able to check predictive ability of the scores, for mortality. CONCLUSIONS: We found that POSSUM had moderate discrimination and good calibration for morbidity prediction in head and neck cancer surgeries, as well as for the selected subgroup.

Obstructive sleep apnoea and its knowledge and attitude among Indian anaesthesiolgists - A survey study.

BACKGROUND AND AIMS: Obstructive sleep apnoea (OSA) has an estimated prevalence of 2%-4% in adult population and is increasing. Most of these are detected late which is the cause for higher perioperative morbidity. This survey was aimed to seek the level of knowledge and attitude of Indian anaesthesiologists towards OSA. METHODS: The OSA Knowledge and Attitude (OSAKA) questionnaire (23-statements) was distributed to the anaesthesiologists attending the difficult airway conference in December 2017. The first section has 18 statements pertaining to OSA knowledge. The second section consists of five statements to evaluate self-confidence in the management of OSA. Age, gender, professional title, type of hospital, years of experience, and bariatric experience were analysed. RESULTS: 205 out of 350 participants responded. In all, 201 (57.4%) fully completed responses were analysed. The mean ± standard deviation knowledge and attitude scores were 12.01 ± 2.88 (66.72% ± 16%) and 18.16 ± 3.75 (72.64% ± 15%) respectively. On exclusion of junior residents (n = 56), knowledge and attitude scores of qualified anaesthesiologists were 12.7 ± 2.55 (70.55% ± 14.16%) and 18.78 ± 3.91 (75.12% ± 15.64%), respectively. Anaesthesiologists with bariatric experience had a significantly higher attitude score when compared with those who do not practice bariatric surgeries (P < 0.01). There is weak but significant, positive linear correlation between knowledge and attitude score (rs= 0.370, P < 0.01). CONCLUSION: Deficit of adequate knowledge about OSA exists among Indian anaesthesiologists. Experience of managing cases with OSA seems to improve knowledge and attitude towards OSA.
